Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
24 ounces cheese tortellini (fresh, frozen, or dried)
1 pound Italian-style sausage (beef or chicken)
32 ounces marinara sauce
1/2 cup chopped onion
2 cups grated mozzarella cheese
Directions
Preheat your oven to 375°F (190°C) and lightly grease a large casserole dish or a 9 x 13 baking dish.
Bring a large pot of water to a boil. While waiting for the water, begin preparing the sauce. Heat a large skillet over medium-high heat and cook the sausage with the chopped onion until fully browned and crumbly. Drain any excess grease if necessary.
Add the marinara sauce to the cooked sausage and onion mixture. Stir well and let it simmer for a few minutes to blend the flavors.
Meanwhile, cook the tortellini according to the package instructions, but reduce the cooking time by about 2–3 minutes so it remains slightly firm. Drain the pasta without rinsing.
Combine the cooked tortellini with the sausage marinara sauce, stirring gently to avoid breaking the pasta.
Layer half of the tortellini mixture into the prepared baking dish and sprinkle half of the mozzarella cheese over the top. Add the remaining tortellini mixture and finish with the rest of the cheese.
Bake in the preheated oven for about 20 minutes, or until the cheese is melted, bubbly, and lightly golden on top. Let it rest for a few minutes before serving.
You can easily customize this casserole to suit your taste. Swap the sausage for ground beef or chicken for a different flavor profile. For a vegetarian version, omit the meat and add sautéed vegetables such as mushrooms, zucchini, or spinach.
If you want a richer dish, mix in a bit of cream or add ricotta cheese between the layers. You can also experiment with different cheeses like cheddar, provolone, or a blend of Italian cheeses for extra depth.
For a spicier version, use a spicy sausage or add chili flakes to the sauce.
Storage/Reheating
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To freeze, place the cooled casserole in a freezer-safe container and store for up to 3 months.
To reheat, warm individual portions in the microwave or cover the dish with foil and heat in the oven at 350°F (175°C) until heated through. If frozen, thaw overnight in the refrigerator before reheating for best results.
