Ingredient Notes & Details

Cheese Tortellini

Fresh or refrigerated tortellini works best for this recipe. It cooks quickly and stays tender after baking. Frozen tortellini also works — just add a few extra minutes to boiling time.

Ground Beef

Adds hearty, savory flavor. You can substitute ground turkey or Italian sausage for a twist.

Marinara Sauce

Use a high-quality jarred marinara or homemade sauce. A rich tomato base is key to achieving that classic baked pasta flavor.

Ricotta Cheese

Creates creamy layers similar to lasagna. For a smoother texture, mix with a little shredded mozzarella before layering.

Mozzarella Cheese

Freshly shredded mozzarella melts best and gives you that beautiful cheesy pull.

Parmesan Cheese

Adds salty depth and enhances the Italian flavors in this baked tortellini casserole.

Garlic & Onion

Essential aromatics that build the flavor foundation.

Italian Seasoning

Adds herbaceous warmth and enhances the tomato sauce beautifully.

Step-by-Step Instructions

Step 1: Cook the Tortellini

Bring a large pot of salted water to a boil. Cook the cheese tortellini just until al dente (usually 2–3 minutes for fresh). Drain and set aside.

Step 2: Prepare the Meat Sauce

In a large skillet over medium heat, cook the ground beef with diced onion until browned. Drain excess grease.

Add minced garlic and cook for 30 seconds until fragrant. Stir in marinara sauce and Italian seasoning. Simmer for 5–7 minutes to develop flavor.

Step 3: Preheat the Oven

Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.

Step 4: Layer the Casserole

Spread a thin layer of meat sauce on the bottom of the dish.

Add half of the cooked tortellini.

Spoon dollops of ricotta over the pasta.

Top with meat sauce and a generous sprinkle of mozzarella.

Repeat layers, finishing with mozzarella and Parmesan on top.

Step 5: Bake

Cover with foil and bake for 20 minutes.

Remove foil and bake another 10–15 minutes until the cheese is bubbly and lightly golden.

Step 6: Rest Before Serving

Let the casserole sit for 5–10 minutes before serving. This helps the layers set and makes slicing easier.

How do I make this recipe vegetarian?
