I love this pasta because it’s creamy, comforting, and incredibly easy to put together. The combination of Italian sausage, cheese-filled tortellini, and a rich tomato-Alfredo sauce creates a warm and satisfying dish that feels perfect for busy evenings or a cozy weekend dinner. Creamy Italian Sausage Tortellini

Why You’ll Love This Recipe

I love how quickly this dish comes together while still tasting like something I spent much more time on. Browning the sausage with onions and garlic builds a deep, savory base, and the tortellini soaks up the creamy sauce beautifully. I also appreciate how adaptable it is—I can add veggies, make it spicier, or lighten it up depending on what I’m in the mood for.

Ingredients

(Tip: You’ll find the full list of Ingredients and measurements in the recipe card below.)

1 lb Italian sausage
1 chopped onion
1 tablespoon minced garlic
15 oz jar Alfredo sauce
15 oz jar marinara sauce
19 oz frozen cheese tortellini
1 teaspoon Italian seasoning
1/4 teaspoon red pepper flakes (optional)
1 cup shredded mozzarella cheese
Parsley flakes (optional, for garnish)

Directions

Heat a large skillet over medium-high heat. Add the Italian sausage and chopped onion. Cook until the sausage is browned and the onions soften, then drain any excess grease.
Reduce the heat to medium-low and stir in the minced garlic, Alfredo sauce, marinara sauce, Italian seasoning, and red pepper flakes if I want extra heat.
Add the frozen cheese tortellini and stir so the pasta is fully coated. Cover the skillet and cook for about 5 minutes, or until the tortellini is heated through and tender.
Sprinkle the mozzarella cheese on top. I either place the skillet in a 400°F oven for a few minutes to melt the cheese, or simply cover it on the stovetop until the cheese becomes gooey.
Garnish with parsley flakes if I want extra color before serving.

Servings And Timing

Serves 4 to 6 people
Prep time: about 10 minutes
Cook time: about 20 minutes
Total time: around 30 minutes

Variations

I sometimes add fresh spinach, mushrooms, or zucchini for extra flavor and nutrition.
Fresh tortellini works just as well and cooks even faster—perfect when I’m in a hurry.
For a lighter version, I use turkey sausage or a lighter Alfredo sauce.
Spicy Italian sausage or extra red pepper flakes give it a nice kick if I want more heat.

Storage/Reheating

I store leftovers in an airtight container in the refrigerator for up to 3 days.
When reheating on the stovetop, I add a splash of milk, cream, or sauce to loosen it and keep everything creamy.
In the microwave, I heat portions in short intervals and stir between heating to avoid drying out.
Freezing is possible, but the tortellini may soften after thawing, so I use this option only when needed.

FAQs

Can I make this recipe ahead of time?

Yes. I can prepare the sauce and sausage ahead of time, then add the tortellini and cheese right before serving.

Can I use fresh tortellini instead of frozen?

Absolutely. Fresh tortellini cooks quickly, so I watch it closely to avoid overcooking.

What vegetables can I add?

Spinach, mushrooms, or zucchini work wonderfully and blend well with the creamy sauce.

How can I make the dish lighter?

I like swapping in turkey sausage, using light Alfredo sauce, or reducing the cheese.

Can I freeze leftovers?

I can freeze them, but the texture of the tortellini may soften once thawed, so I prefer refrigerating when possible.

Creamy Italian Sausage Tortellini has become one of my favorite quick yet indulgent pasta dishes. I love how rich and comforting it is while still being easy enough for a busy weeknight.
