I first had a version of this soup at a small Italian-American diner tucked into a strip mall — the kind of place with checkered tablecloths and bread baskets that never empty. I ordered it on a whim because it was the soup of the day, and I was not prepared for how deeply satisfying it would be. The broth was this gorgeous rusty-orange color, creamy but not heavy, with chunks of sausage that had this slightly fennel-spiced depth to them. The tortellini were soft and cheese-filled, soaking up all that flavor. When I got home I had to recreate it. After a few tries I landed on this version, which I honestly think might even be better. The tomato paste gives it an umami backbone, the cream rounds out the acidity of the tomatoes, and the spinach adds color and a subtle earthiness. It's become one of my most-requested recipes.
Why I love this recipe
What I love most about this recipe is how it manages to feel both effortless and impressive at the same time. You brown the sausage, build the broth, add tortellini and spinach, and you're done — but it tastes like it simmered all day. The combination of textures is what really gets me: tender pasta, meaty chunks of sausage, silky cream, and little pops of tomato. It's one of those soups that doesn't need anything else — it IS the meal. I also love how adaptable it is. Different sausage varieties, different greens, a handful of white beans — it takes every variation in stride. But most of all, I love that every single time I serve it, someone asks for the recipe.
What You Need From Your Kitchen
- Italian Sausage: Remove from casings and crumble into a hot pot, browning until cooked through and slightly caramelized for maximum flavor.
- Cheese Tortellini: Use fresh or refrigerated tortellini and add directly to the simmering broth — they cook quickly and soak up all the flavors.
- Baby Spinach: Stir in at the very end and let it wilt gently — it adds color, nutrients, and a subtle earthy note to the creamy broth.
- Diced Tomatoes: Use the whole can including the juices to build the base of the broth and add brightness and acidity.
- Heavy Cream: Pour in off the heat to create that luscious, velvety broth that makes this soup so irresistible.
- Tomato Paste: Cook it briefly with the aromatics before adding liquids — this step deepens the color and adds a rich umami backbone to the soup.
- Chicken Broth: Use a good-quality broth as the soup base; it carries the flavor of every other ingredient.
Let's Make These Together
- Brown the sausage first
- Start by cooking the Italian sausage in your pot over medium-high heat, breaking it into crumbles as it cooks. Let it get nicely browned — those caramelized bits at the bottom of the pot are pure flavor gold that will infuse your entire broth.
- Build your aromatic base
- Once the sausage is cooked, add your diced onion right into the same pot. Let it soften in the rendered fat, then add garlic and tomato paste. Cooking the tomato paste for a couple of minutes before adding liquid is the secret step that gives this soup its deep, complex flavor.
- Pour in the broth and tomatoes
- Add your chicken broth, canned diced tomatoes with all their juices, Italian seasoning, and red pepper flakes. Bring everything up to a boil and let the flavors start melding together while the soup comes to life.
- Drop in the tortellini
- Add the fresh cheese tortellini directly into the boiling soup. They only take about 5–7 minutes, so watch them closely. They're done when they float to the top and are tender all the way through.
- Finish with cream and spinach
- Turn the heat down to low and pour in the heavy cream slowly, stirring as you go. Then add the baby spinach and let it wilt into the soup. Season with salt and pepper, ladle into bowls, and pile on the Parmesan.

Switch Things Up
One night I had leftover Italian sausage and a bag of cheese tortellini about to expire, and I just threw them together with whatever broth and cream I had. I honestly didn't expect much — but the result was so good my family demanded I write it down. Now I make it intentionally. Sometimes I swap the spinach for kale, or throw in a can of white beans for extra heartiness. You can even use spicy sausage if you want a kick. The base is so forgiving and flavorful that it's hard to mess up.
Perfect Pairings
This creamy soup pairs beautifully with a thick slice of crusty sourdough or warm garlic bread for dipping into that rich broth. A simple arugula salad dressed with lemon and olive oil balances the richness perfectly. For drinks, a light-bodied Italian red like a Chianti or even a sparkling water with lemon keeps things refreshing alongside all that savory depth.

Frequently Asked Questions
- → Can I use frozen tortellini instead of fresh?
Yes! Frozen tortellini works fine in this soup. Just add it to the boiling broth and cook for 1–2 minutes longer than the package directions suggest, since it starts from frozen. The texture is slightly chewier but still delicious.
- → Can I make this soup ahead of time?
You can prepare the soup base (everything except the tortellini, cream, and spinach) up to 2 days ahead. When ready to serve, reheat the base, add the tortellini and cook through, then finish with cream and spinach. This prevents the pasta from getting soggy.
- → How do I store and reheat leftovers?
Store cooled leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over low-medium heat, adding a splash of chicken broth if the soup has thickened too much.
- → Can I substitute the heavy cream for something lighter?
Half-and-half works well and cuts some of the richness while still giving a creamy result. Full-fat coconut milk is a dairy-free option that works surprisingly well. Avoid using regular milk as it may curdle in the hot soup.
- → What type of sausage works best in this recipe?
Sweet or mild Italian sausage is the classic choice and keeps the flavor balanced. Hot Italian sausage is great if you want more heat. You can also use chicken or turkey Italian sausage for a lighter version — it still delivers excellent flavor.
- → Can I add other vegetables to this soup?
Absolutely! Diced zucchini, sliced mushrooms, bell peppers, or white beans are all fantastic additions. Add heartier vegetables when you add the broth, and more delicate ones like zucchini closer to the end to avoid overcooking.
