- 1 large yellow onion, diced
- 2 carrots, peeled and diced
- 2 celery stalks, diced

Before You Start: Tips & Ingredient Notes
- Choosing your sausage. You can use mild or hot Italian sausage based on your heat preference. If you’re using links, just squeeze the meat out of the casings. The fat rendered from browning the sausage is gold — we’ll use it to cook our vegetables, so don’t drain it!
- Don’t skip the veggie sauté. This step isn’t just about softening the onions, carrots, and celery. Cooking them in the sausage drippings and oil until they’re slightly softened and fragrant is what builds a deep, savory base for the entire soup. You’ll know it’s ready when the onions turn translucent and the whole kitchen smells amazing.
- Prepping the kale. Make sure to remove the tough, fibrous stems from the kale leaves before chopping. They can be a bit bitter and chewy. The leaves will seem like a lot at first, but they wilt down significantly in the hot broth, so don’t worry — it will all fit!
- Broth matters. Since the sausage can be quite salty, I highly recommend using a low-sodium chicken broth. This gives you full control over the final seasoning. You can always add more salt at the end, but you can’t take it out.
How to Make Italian Sausage and Kale Soup
Step 1: Heat the olive oil in a large Dutch oven or heavy-bottomed pot over medium-high heat. Add the Italian sausage (with casings removed) and use your wooden spoon to break it up into crumbles. Cook for about 6-8 minutes, stirring occasionally, until the sausage is nicely browned and cooked through. You’ll notice a good amount of flavorful fat has rendered into the pot — that’s exactly what we want.
Step 2: Add the diced onion, carrots, and celery to the pot with the sausage. Cook, stirring frequently, for about 5-7 minutes, until the vegetables have softened and the onions become translucent. The aroma at this stage is just incredible. Now, add the minced garlic and cook for one more minute until fragrant — be careful not to let the garlic burn.
Step 3: Pour in the chicken broth and the canned diced tomatoes with their juices. Scrape the bottom of the pot with your spoon to lift up all those delicious browned bits — that’s where so much flavor is hiding! Add the cubed potatoes, dried oregano, and red pepper flakes if using. Give everything a good stir.
Step 4: Bring the soup to a boil, then immediately reduce the heat to low, cover the pot, and let it simmer gently for about 15-20 minutes. The potatoes should be tender and easily pierced with a fork. You’ll notice the broth has thickened slightly from the potatoes and the colors have deepened.
Step 5: It’s kale time! Stir in the chopped kale leaves, a handful at a time. They will seem voluminous, but they’ll wilt down into the hot broth within a few minutes. Continue to simmer the soup, uncovered, for another 5-7 minutes, just until the kale is tender and has turned a vibrant green. Taste the soup and season with salt and black pepper as needed.
Step 6: Ladle the hot soup into bowls and top generously with grated Parmesan cheese. The salty, umami punch from the Parmesan is the perfect finishing touch that brings all the flavors together. Serve immediately and enjoy the warmth!
Storage & Freshness Guide
- Fridge: Cool completely and store in an airtight container for up to 4 days.
- Freezer: Freeze before adding kale and potatoes for best texture; thaw, reheat, and add fresh greens/potatoes.
- Reviving: Reheat gently on stovetop, adding a splash of broth if too thick.
Serving Suggestions
Complementary Dishes
- Crusty garlic bread — There’s nothing better than a thick, toasted slice for dipping into that savory broth and scooping up bits of sausage and potato. It’s a textural dream.
- A simple arugula salad — The peppery freshness of arugula dressed with a light lemon vinaigrette provides a bright, crisp contrast to the rich, hearty soup.
- Cheesy polenta — Spooning this soup over a creamy bed of Parmesan polenta turns it into an ultra-comforting, almost stew-like meal that’s incredibly satisfying.
Drinks
- A medium-bodied red wine — A Chianti or Sangiovese has enough acidity to cut through the richness of the sausage and stands up well to the herbal notes in the soup.
- A crisp Italian lager — The light, effervescent quality of a lager cleanses the palate between bites and complements the savory flavors without overpowering them.
- Sparkling water with lemon — For a non-alcoholic option, the bubbles and citrus are wonderfully refreshing and help balance the heartiness of the dish.
Something Sweet
- Lemon ricotta cookies — Their light, cake-like texture and bright, zesty glaze are a perfect, not-too-heavy finish after a savory soup.
- Dark chocolate affogato — A scoop of vanilla gelato drowned in a shot of hot espresso and shaved dark chocolate is a decadent, restaurant-style ending that feels special.
- Almond biscotti — The crunchy, nutty cookies are classic for a reason; they’re perfect for dipping into a post-dinner coffee or dessert wine.
Top Mistakes to Avoid
- Mistake: Overcrowding the pot when browning the sausage. If you add too much sausage at once, it will steam instead of brown, and you’ll miss out on all that delicious, caramelized flavor. Cook it in batches if your pot is on the smaller side.
- Mistake: Adding the kale too early. If you put the kale in at the same time as the potatoes, it will overcook, lose its vibrant color, and become unpleasantly mushy. I’ve messed this up before too — adding it at the end ensures it stays tender but still has a bit of structure.
- Mistake: Not seasoning at the end. Sausage and broth salt levels can vary wildly. Always taste your soup after it’s finished cooking and just before serving to adjust the salt and pepper. It makes a world of difference.
- Mistake: Boiling too vigorously after adding the potatoes. A gentle simmer is all you need to cook the potatoes through without them breaking apart and turning the soup starchy and cloudy.
Expert Tips
- Tip: Brown the sausage well. Don’t just cook it until it’s no longer pink; let it get a proper sear and develop some crispy, browned bits. This Maillard reaction adds a deep, meaty complexity that forms the soul of the soup.
- Tip: Use the sausage fat. That rendered fat from browning the sausage is packed with flavor. It’s the perfect medium for sautéing your aromatic vegetables, so they soak up all that savory goodness.
- Tip: Add a Parmesan rind. If you have a leftover rind of Parmesan cheese in your fridge, toss it into the soup while it simmers. It will melt slightly, adding an incredible layer of umami and richness to the broth.
- Tip: Let it rest. If you have the time, turn off the heat and let the soup sit for 10-15 minutes before serving. This allows the flavors to meld even more and the soup to cool to the perfect eating temperature.
FAQs
Can I make this soup ahead of time?
Absolutely, and it might even be better! This soup is a fantastic make-ahead meal. Let it cool completely after cooking, then store it in an airtight container in the refrigerator for up to 4 days. The kale will soften further, and the flavors will deepen beautifully. Reheat it gently on the stovetop, adding a splash of broth if it has thickened too much.
Can I use a different green instead of kale?
Of course. Swiss chard or escarole would be excellent, straightforward swaps. Spinach will also work, but add it at the very end, just until it wilts, as it cooks much faster than kale. If you’re using a tougher green like collards, you’d want to add them earlier, with the potatoes, so they have time to become tender.
Is it possible to make this soup creamy?
It sure is! For a creamy version, stir in about 1/2 cup of heavy cream or half-and-half during the last 5 minutes of cooking. You could also blend a cup of the finished soup (without kale) and stir it back in to naturally thicken the broth. Both methods add a lovely, rich silkiness.
Can I freeze Italian Sausage and Kale Soup?
You can, but with one caveat: the kale and potatoes can become a bit soft and grainy upon thawing. For best results, freeze the soup before adding the kale and potatoes. When you’re ready to eat, thaw, reheat, and then add freshly cooked potatoes and kale for the last 10 minutes of simmering.
My soup is too thin. How can I thicken it?
A couple of easy fixes! You can mash some of the cooked potatoes against the side of the pot with a fork and stir them in — this will naturally thicken the broth. Alternatively, make a quick slurry by mixing a tablespoon of cornstarch with two tablespoons of cold water, then stir it into the simmering soup and cook for another minute or two until thickened.
