There’s nothing like a big, cozy bowl of pasta soup when the weather cools off or you’ve just had one of those days. This version is extra creamy, loaded with cheese tortellini, crumbled Italian sausage, juicy tomatoes, and tender spinach in a rich garlic-parmesan broth.

It tastes like a mash-up of your favorite Italian restaurant pasta and a comforting homemade soup, but it all comes together in one pot on the stovetop. It’s hearty, kid-friendly, and perfect for busy weeknights when you want real comfort food without a mountain of dishes.

Why You’ll Love This The BEST Pasta Soup

This soup is the definition of simple comfort. Most of the ingredients are pantry or fridge staples—broth, canned tomatoes, tortellini, cream, and a handful of fresh spinach—plus a pack of Italian sausage for big flavor with very little effort.

Because everything simmers in one pot, you get layers of flavor in every spoonful: savory sausage, a velvety tomato-cream base, and pockets of cheesy pasta. Leftovers reheat beautifully, so lunch the next day is already sorted.

This recipe is also incredibly flexible. Swap the sausage for ground turkey, skip the red pepper flakes if you’re serving spice-sensitive eaters, or use whatever stuffed pasta you have on hand. It’s easy to adjust but always tastes like you spent way more time on it than you actually did.

What Kind of Pasta Works Best in This Soup?

For that cozy, restaurant-style feel, I love using refrigerated cheese tortellini. It cooks quickly right in the broth and releases a bit of starch, naturally thickening the soup so it turns silky and rich.

If tortellini isn’t available, refrigerated or frozen mini ravioli or small cheese-filled pasta shapes also work well—just keep an eye on the package directions for timing and adjust the simmering time so the pasta turns tender but not mushy.

Dry pasta can be used in a pinch (small shapes like ditalini or mini shells are best), but I find stuffed pasta makes this soup feel extra special and satisfying.

Ingredients for The BEST Pasta Soup

To build deep, cozy flavor in this pasta soup, we’re layering simple ingredients that each bring something important to the pot—richness, body, or freshness at the end.

Italian sausage
- Adds a savory, meaty base and plenty of seasoning so you don’t have to fuss with lots of extra spices.
Olive oil
- Helps brown the sausage and vegetables and prevents sticking if your sausage is on the lean side.
Yellow onion
- Brings sweetness and depth to the broth as it softens and cooks down.
Fresh garlic
- Infuses the soup with that classic garlicky warmth that pairs perfectly with tomatoes and cream.
Italian seasoning
- A handy blend of herbs (like oregano and basil) that gives instant Italian-inspired flavor.
Crushed red pepper flakes (optional)
- A small pinch gives the soup a gentle kick and keeps the creaminess from tasting flat.
Low-sodium chicken broth
- Forms the savory backbone of the soup and lets you control the salt level.
Diced tomatoes with their juices
- Add brightness, acidity, and bits of tomato throughout the bowl.
Heavy cream
- Makes the broth luxuriously smooth and creamy without needing a roux.
Freshly grated Parmesan cheese
- Melts into the soup to thicken slightly and adds salty, nutty richness.
Refrigerated cheese tortellini
- The star of the show—tender pasta pockets filled with cheese that turn the soup into a full meal.
Fresh baby spinach
- Wilts into the hot soup at the end for a pop of color and extra veggies.
Butter
- A small pat stirred in right before serving adds sheen and a restaurant-style finish.
Salt and freshly ground black pepper
- Essential for balancing all the flavors and making everything pop.

How To Make The BEST Pasta Soup

Before you start, grab a large heavy-bottomed pot or Dutch oven so you have plenty of room for the broth and tortellini to simmer.

Step 1: Brown the sausage

Add the Italian sausage to your pot over medium heat, drizzling in a little olive oil if needed. Cook, breaking it up with a spoon, until it’s browned and no pink remains. This step builds a flavorful base with all those tasty browned bits on the bottom of the pan.

Step 2: Soften the aromatics

Stir in the chopped onion and cook until it’s soft and translucent, scraping up any browned bits from the sausage. Add the minced garlic and cook just until fragrant—about 30 seconds—so it doesn’t burn.

Step 3: Season and deglaze

Sprinkle in the Italian seasoning, red pepper flakes (if using), salt, and pepper. Pour in the chicken broth and stir, scraping along the bottom of the pot to release anything stuck on. Add the diced tomatoes with their juices and bring everything to a gentle boil.

Step 4: Simmer with the tortellini

Add the cheese tortellini to the pot and reduce the heat to a lively simmer. Cook according to the package directions, stirring now and then, until the pasta is just tender. The broth will start to thicken slightly as the tortellini cooks.

Step 5: Make it creamy

Lower the heat so the soup is just barely simmering, then pour in the heavy cream and stir in the grated Parmesan. Warm the soup gently, without letting it boil hard, until the cheese is melted and the broth turns silky and creamy.

Step 6: Finish with spinach and butter

Stir in the chopped spinach and cook for 1–2 minutes until it wilts. Add the butter and taste, adjusting with more salt and pepper if needed. Ladle the soup into bowls and serve hot with extra Parmesan on top.

How to Serve and Store This Pasta Soup

This recipe makes a generous pot of soup—about 6 hearty servings—so it’s ideal for feeding a hungry family or saving some for lunch the next day.

Serve the soup piping hot with a shower of extra Parmesan, freshly cracked pepper, and a side of crusty bread or garlic bread for dunking. A simple green salad on the side balances the richness without adding much extra work.

Leftovers keep well in an airtight container in the fridge for up to 3 days. The tortellini will continue to absorb some liquid as it sits, so you may want to thin reheated portions with a splash of broth or milk. Reheat gently over low heat on the stovetop or in the microwave, avoiding a full boil so the cream doesn’t separate.

For best texture, I don’t recommend freezing this soup as the cream and tortellini can become grainy and mushy once thawed.
