Hearty Italian Sausage and Kale Soup

Soup season truly holds a special place in our hearts, and over the years, we’ve perfected countless recipes designed for maximum comfort. From our rich Dutch Oven Beef Stew to this delightful Italian Sausage and Kale Soup, each dish is crafted to bring warmth and satisfaction to your table. This particular recipe embodies everything you desire in a comforting bowl of soup: a harmonious blend of rich flavors, simple, wholesome ingredients, and just the right amount of heartiness to fill you up.

Through extensive testing, we’ve discovered that the choice of pasta significantly impacts the overall experience of soups like this. Our top recommendations are small-shaped varieties such as ditalini or orzo. These pastas are ideal because they maintain their delightful shape and texture, absorbing just enough of the savory broth without becoming overly soft or mushy. This ensures every spoonful is packed with flavor and a pleasant chew. It’s a testament to the fact that exceptional soup doesn’t need to be overly complicated to taste truly incredible.

What truly elevates this Italian Sausage and Kale Soup is the thoughtful layering of flavors. It begins with the robust, savory notes of browned Italian sausage, which forms the foundation of the broth. This is beautifully complemented by a medley of aromatic spices like seasoned salt, celery salt, garlic, and bay leaves, all brought together with a subtle hint of Worcestershire sauce for an added layer of umami. Despite this depth of flavor, the entire recipe comes together effortlessly in four easy steps, making it an incredibly reliable and satisfying option for busy weeknights or relaxed, cozy weekends alike.

Italian Sausage Kale Soup Ingredients

Crafting this flavorful Italian Sausage and Kale Soup requires a thoughtful selection of fresh, high-quality ingredients. Here’s what you’ll need, along with a few notes to help you choose the best for your pot:

• Olive Oil: A good quality extra virgin olive oil forms the base for sautéing our aromatics and browning the sausage.
• Italian Sausage: We recommend a mild or sweet Italian sausage, removed from its casing, for a balanced flavor profile. If you prefer a bit of a kick, spicy Italian sausage works wonderfully too.
• Aromatic Vegetables (Mirepoix):
  • Onions: Diced, they provide a sweet and savory foundation.
  • Carrots: Adds natural sweetness and vibrant color.
  • Celery: Contributes a subtle, earthy flavor and essential texture to the soup base.
• Canned Diced Tomatoes: A 14 oz. can of diced tomatoes adds acidity and a rich tomato base to the broth. Fire-roasted diced tomatoes can introduce a lovely smoky depth.
• Flavor Boosters:
  • Seasoned Salt: A blend of spices that adds comprehensive seasoning.
  • Worcestershire Sauce: A secret weapon for umami and depth of flavor.
  • Celery Salt: Enhances the celery notes and adds an extra layer of savory seasoning.
  • Garlic Powder: Provides a consistent garlic flavor throughout the soup. Fresh minced garlic can also be used.
  • Bay Leaves: Infuses the broth with a subtle, aromatic herbal note, which should be removed before serving.
• Fresh Green Beans: Chopped green beans add a fresh, slightly crisp texture and an additional layer of vibrant green.
• Liquids:
  • Chicken Broth or Stock: The backbone of our soup. Use a good quality, low-sodium broth to control the saltiness. Homemade is always best!
  • Water: Helps to thin the broth to your desired consistency and ensures enough liquid for the pasta.
• Pasta: Small-shaped pasta like ditalini or orzo is ideal as it cooks quickly and is easy to eat with a spoon.
• Fresh Kale: The star green of the soup, providing earthy flavor and a wealth of nutrients.
• Frozen Corn: Adds a pop of sweetness and bright color, best added towards the end.
• Fresh Parsley: Chopped, for a final flourish of freshness and a bright, herbaceous aroma.
• Kosher Salt and Fresh Black Pepper: To taste, for seasoning and balancing the flavors.

Best Kind of Kale for Italian Soup

When it comes to selecting kale for your Italian soup, you have a few excellent options that will all yield delicious results. Lacinato kale, also known as Dinosaur kale, Tuscan kale, or Cavolo Nero, is a fantastic choice. Its dark, sturdy leaves have a slightly sweeter and more tender texture once cooked, making it a favorite for soups. Alternatively, common curly kale works just as wonderfully; its ruffled leaves hold up well to simmering and absorb the flavors of the broth beautifully.

If kale isn’t readily available or if you’re looking to change things up, this recipe is quite flexible. You can easily substitute the kale with other leafy greens such as collard greens, fresh spinach, or Swiss chard. Just note that more tender greens like spinach will cook much faster, so they should be added even closer to the end of the cooking process to prevent them from becoming too wilted or mushy.

How to Make Italian Sausage Kale Soup

This heartwarming Italian Sausage and Kale Soup comes together with surprising ease, making it a perfect meal for any day of the week. Follow these simple steps for a robust and satisfying dish:

1. Brown the Sausage: In a large Dutch oven or a heavy-bottomed pot, heat the olive oil over medium-high heat. Add the Italian sausage (removed from its casing) and cook, breaking it up with a spoon, until it’s no longer pink and is beautifully browned, typically about 5 minutes. The browned bits at the bottom of the pan, known as “fond,” will add immense flavor to your soup.
2. Sauté the Aromatics: Drain off any excess fat from the pot, leaving a little for flavor. Add the diced onions, carrots, and celery to the pot. Cook, stirring occasionally, until the vegetables begin to soften and become translucent, which usually takes another 5 to 7 minutes. This step builds the aromatic foundation of your soup.
3. Simmer the Broth: Pour in the canned diced tomatoes, followed by the seasoned salt, Worcestershire sauce, celery salt, garlic powder, bay leaves, fresh green beans, chicken stock, and water. Stir everything well to combine. Bring the mixture to a gentle simmer, then reduce the heat to medium. Add the small-shaped pasta and continue to simmer, uncovered, for about 15 minutes, or until the pasta is al dente (cooked but still firm to the bite). Remember to taste the soup at this stage and adjust salt and pepper if needed before adding the final greens.
4. Finish with Greens and Garnish: Stir in the chopped kale and frozen corn. Continue to simmer for an additional 7-10 minutes, or until the kale has wilted to your desired tenderness and the corn is heated through. Remove the pot from the heat, carefully take out the bay leaves, and stir in the fresh chopped parsley. Serve immediately and enjoy!

To Make in the Instant Pot

The Instant Pot offers a convenient way to prepare this Italian Sausage and Kale Soup, condensing cooking time while locking in flavors. Here’s how to adapt the recipe for your pressure cooker:

• Sauté: Start by using the “Sauté” function on your Instant Pot. Add the olive oil, then brown the Italian sausage, breaking it apart. Drain any excess fat. Add the diced onions, carrots, and celery, and sauté until softened, about 5-7 minutes.
• Pressure Cook: Pour in the canned diced tomatoes, seasoned salt, Worcestershire sauce, celery salt, garlic powder, bay leaves, green beans, chicken stock, and water. Stir everything together. Secure the lid, ensure the venting knob is sealed, and set to “Manual” or “Pressure Cook” on high pressure for 15 minutes.
• Release Pressure: Once cooking is complete, allow the pressure to naturally release for 10 minutes. Then, carefully perform a quick release of any remaining pressure before opening the lid.
• Finish and Serve: While the soup is pressure cooking, you can cook the small-shaped pasta in a separate pot on the stovetop according to package directions. Alternatively, you can add the pasta directly to the Instant Pot after pressure release and simmer on the “Sauté” setting until tender. Stir in the kale and frozen corn, cooking until the kale is wilted (about 5-7 minutes). Finally, stir in the fresh chopped parsley right before serving.

To Make in the Slow Cooker

For a hands-off approach that allows flavors to deepen beautifully over several hours, the slow cooker is an excellent choice for this Italian Sausage and Kale Soup:

• Initial Sauté: Begin by sautéing the Italian sausage in a skillet on the stovetop over medium-high heat until it’s browned and cooked through. Drain any excess fat. Add the onions, carrots, and celery to the same skillet and cook until softened, about 5-7 minutes. This initial browning step is crucial for developing rich flavors that the slow cooker alone cannot achieve.
• Combine in Slow Cooker: Transfer the browned sausage and sautéed vegetables to the bowl of your slow cooker. Add the canned diced tomatoes, seasoned salt, Worcestershire sauce, celery salt, garlic powder, bay leaves, green beans, chicken broth, and water. Stir all the ingredients well to combine.
• Slow Cook: Cover the slow cooker with its lid and cook on low for 8 hours or on high for 4-6 hours. The longer, slower cooking time allows the flavors to meld and deepen wonderfully.
• Final Steps: About 30-40 minutes before serving, add the small-shaped pasta, kale, and frozen corn to the slow cooker. Stir well and continue to cook until the pasta is tender and the kale is wilted to your liking. Remove the bay leaves before serving. Sprinkle in the fresh chopped parsley right before serving to add a burst of freshness.

Italian Sausage and Kale Soup Substitutions

This Italian sausage and kale soup recipe is wonderfully versatile, allowing for many delicious substitutions and additions to suit your taste, dietary needs, or what you have on hand. Feel free to get creative!

• Sausage Varieties: While we love mild and/or sweet Italian sausage for its balanced flavor, spicy Italian sausage will add a fantastic kick. For a leaner protein option, consider using turkey Italian sausage or even ground chicken or pork seasoned with Italian herbs. For a vegetarian option, skip the sausage entirely and add extra vegetables or plant-based protein.
• Vegetable Swaps & Additions: This soup is a great way to load up on veggies! Besides the core ingredients, consider adding:
  • Leafy Greens: Spinach, collard greens, or Swiss chard are excellent alternatives to kale. Remember that spinach cooks very quickly.
  • Heartier Veggies: Cubed russet or red potatoes (added with the broth), broccoli florets, cauliflower florets, or zucchini (added with the kale and corn) are all great additions. Peas or bell peppers also add color and sweetness.
  • Legumes: For extra protein and fiber, a can of cannellini beans (white kidney beans), chickpeas, or even red kidney beans, rinsed and drained, can be stirred in with the kale.
• Broth Options: The quality of your stock makes a big difference. Whether you opt for homemade chicken stock for the richest flavor or a good-quality store-bought version, ensure it’s low-sodium if you want to control the seasoning. For a vegetarian or vegan version, simply use vegetable broth.
• Pasta Alternatives: Small-shaped pastas like ditalini are perfect, but feel free to use other small varieties such as orzo, elbow macaroni, small shell pasta, or even broken spaghetti. For a gluten-free option, use your favorite gluten-free pasta, ensuring it holds its shape well. To make the soup keto-friendly, omit the pasta entirely or use a low-carb pasta alternative.
• Enhancing Flavor Further:
  • Fresh Herbs: Toss in a few sprigs of fresh thyme, rosemary, or a combination of Italian herbs with the bay leaves for a more complex aroma.
  • Smoky Notes: Replace regular diced tomatoes with fire-roasted diced tomatoes for a subtle smoky flavor.
  • Creaminess: For a richer, creamier soup, stir in a splash of heavy cream, half-and-half, or a dairy-free alternative like unsweetened coconut milk (for a different flavor profile) right before serving.
  • Acidity: A squeeze of fresh lemon juice stirred in just before serving can brighten all the flavors beautifully.
  • Cheese Rind: For an authentic Italian touch and an extra layer of umami, simmer a three-inch piece of Parmesan cheese rind with the broth and remove it before serving.

Expert Recipe Tips for the Best Italian Sausage & Kale Soup

Elevate your Italian Sausage and Kale Soup with these tried-and-true tips and tricks. Whether you’re a beginner or an experienced cook, these insights will help you achieve a truly exceptional bowl of soup tailored to your preferences.

• Brown the Sausage Properly for Deep Flavor: Don’t rush this crucial step! Cook the Italian sausage over medium-high heat until it’s beautifully golden brown and caramelized. This browning creates what’s called “fond” (the flavorful bits that stick to the bottom of the pan), which will deglaze into the broth, giving your soup an incredibly rich and complex flavor base.
• Uniform Vegetable Dicing for Even Cooking: To ensure all your vegetables cook at the same rate and offer a pleasant texture in every spoonful, make sure to cut them into small, even-sized pieces. This also contributes to a more appealing presentation of your finished soup.
• Vegetarian Version Made Easy: To transform this hearty soup into a delicious vegetarian meal, simply substitute the Italian sausage with a plant-based alternative or omit it entirely. Replace chicken broth with a high-quality vegetable broth, and consider adding extra robust vegetables like mushrooms or zucchini for added substance.
• Keto-Friendly Adaptation: For those following a keto diet, this soup can be easily adjusted. Simply omit the pasta or opt for a low-net-carb alternative such as shirataki noodles, zucchini noodles, or cauliflower rice, which can be stirred in towards the end of cooking. Ensure all other ingredients are compliant with your keto plan.
• Prep Ahead for Quick Weeknight Meals: To make cooking this dish even faster on busy days, chop all your vegetables (onions, carrots, celery, kale, green beans) ahead of time. You can store them in airtight containers in the refrigerator for up to 2-3 days, significantly cutting down on active cooking time.
• Boost Flavor with Parmesan Rind: For an authentic Italian touch and an incredible depth of umami, toss in a three-inch piece of Parmesan cheese rind when you add the chicken broth. Let it simmer with the soup, then remove it before serving. It imparts a subtle, cheesy richness that’s truly delicious.
• Brighten with Fresh Lemon Juice: A little acidity can make all the difference. Squeeze some fresh lemon juice into the soup right before serving. This simple addition brightens the overall flavor profile, making the soup taste fresh and vibrant.
• Don’t Overcook the Pasta: Small-shaped pasta cooks quickly. Add it at the suggested time and cook until just al dente to prevent it from becoming mushy. If you anticipate a lot of leftovers, consider cooking the pasta separately and adding it to individual bowls to prevent it from soaking up too much broth.
• Adjust Seasoning Throughout: Taste your soup at various stages of cooking—after browning the sausage, after simmering the broth, and before serving. Adjust the salt and pepper as needed to ensure the flavors are perfectly balanced.

How to Serve Italian Sausage and Kale Soup

This easy Italian Sausage and Kale Soup is a complete meal in itself, but it truly shines when paired with a few complementary sides. The warmth and heartiness of the soup are perfectly balanced by something crisp or absorbent.

For dipping and soaking up every last drop of flavorful broth, a variety of bread options are fantastic. Consider serving it with classic French bread, rustic cornbread, or a simple crusty roll. Some excellent homemade bread accompaniments include Sourdough Garlic Bread, light and airy Cheese Popovers, delicate Parmesan Cheese Crisps, or a savory Gluten-Free Cheese Bread. For a lighter side, a crunchy green salad with a simple vinaigrette provides a refreshing contrast to the rich soup. Don’t forget garnishes! A sprinkle of freshly grated Parmesan cheese, a swirl of extra virgin olive oil, or a pinch of red pepper flakes can elevate each bowl.

How to Store Italian Sausage Kale Soup

One of the best qualities of this Italian Sausage and Kale Soup is that its flavors deepen and meld beautifully over time, often tasting even better the day after it’s made! This makes it an excellent candidate for meal prep or for enjoying as delicious leftovers.

Refrigeration: Allow any leftover soup to cool completely to room temperature before transferring it to an airtight container. When stored properly in the refrigerator, the soup will remain fresh and delicious for up to 3-4 days. We highly recommend using sturdy, leak-proof containers to prevent any spills and maintain freshness.

Freezing: This soup freezes exceptionally well, making it perfect for preparing a double batch to enjoy later. Once cooled, portion the soup into freezer-safe airtight containers or heavy-duty freezer bags. Lay freezer bags flat to freeze, which saves space. The soup can be safely frozen for up to 3 months. We particularly love these specific containers for their freezer-friendly design.

Reheating: To reheat, simply thaw the frozen soup in the refrigerator overnight. Once thawed (or if reheating from the fridge), gently warm it on the stovetop over medium-low heat, stirring occasionally, until it’s heated through. You can also reheat individual portions in the microwave. If the soup appears too thick after reheating, you can add a splash of chicken broth or water to achieve your desired consistency.

Absolutely! Frozen kale works perfectly in this soup. Soups are an excellent way to utilize frozen vegetables as their texture doesn’t need to be perfectly crisp or crunchy. Just add it directly from the freezer; it will thaw and soften beautifully in the hot broth.

Kale cooks quite quickly when submerged in hot soup. If you prefer your kale to be tender and soft, it typically needs about 5 to 7 minutes of simmering. If you enjoy your kale with a little more bite and a slightly firmer texture, simply turn off the heat right after adding it and let the residual heat do the work for a minute or two.

For a deliciously creamy Italian Sausage and Kale Soup, you can easily incorporate a dairy element. Stir in about ½ to 1 cup of heavy cream, half-and-half, or even unsweetened full-fat coconut milk (for a dairy-free option, though it will slightly alter the flavor profile) right before you add the fresh parsley and remove the soup from the heat. Heat gently to warm through without boiling.

Yes, absolutely! To make it vegetarian, simply substitute the Italian sausage with a plant-based sausage alternative or omit it, and use vegetable broth instead of chicken broth. For a vegan version, ensure your plant-based sausage is vegan, use vegetable broth, and omit any creamy additions like heavy cream. You can add extra beans or hearty vegetables for more substance.

Any small-shaped pasta will work wonderfully! Great alternatives include elbow macaroni, small shells, stelline (star-shaped pasta), or even broken pieces of spaghetti or vermicelli. The key is using pasta that is easy to eat with a spoon and cooks relatively quickly.
