Equipment You’ll Need
-
Large pot (for boiling tortellini)
-
Large skillet (for sautéing onions and garlic)
-
9×13-inch baking dish
-
Mixing bowls
-
Spatula or wooden spoon
-
Aluminum foil (for baking)
Step-by-Step Instructions
Step 1: Preheat Oven
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch casserole dish and set it aside.
Step 2: Cook the Tortellini
Bring a large pot of salted water to a boil. Add cheese tortellini and cook according to the package directions—typically 3 to 5 minutes if fresh or 8 to 10 minutes if frozen. Drain and set aside.
Tip: Slightly undercook the tortellini by 1 minute since it will finish cooking in the oven.
Step 3: Make the Sauce
In a large skillet over medium heat, add olive oil. Once hot, add chopped onions and cook for 3 to 4 minutes until softened. Add garlic and cook for another 30 seconds.
Stir in marinara sauce, tomato paste (if using), oregano, basil, red pepper flakes, salt, and pepper. Let the sauce simmer for about 5 minutes to deepen the flavor.
Step 4: Combine Pasta and Sauce
Add the drained tortellini to the sauce and toss until everything is well coated. If using any add-ins (like sausage or veggies), stir them in now.
Step 5: Assemble the Casserole
Pour half of the tortellini mixture into the prepared casserole dish. Sprinkle with half of the mozzarella and provolone cheeses. Add a layer of half the pepperoni.
Repeat with the remaining tortellini, cheeses, and pepperoni. Top with grated Parmesan.
Step 6: Bake
Cover the casserole with foil and bake for 20 minutes. Then, uncover and bake for another 10–15 minutes, or until the cheese is melted, bubbly, and golden brown.
Step 7: Garnish and Serve
Remove the casserole from the oven and let it rest for 5 minutes. Sprinkle with chopped fresh basil or parsley for color and flavor. Serve warm and enjoy the ultimate comfort dish!
Make-Ahead and Freezer Tips
Make-Ahead:
You can prepare the casserole up to 24 hours ahead of time. Assemble everything in the baking dish, cover with foil, and refrigerate. When ready to cook, bake as directed—adding 10 extra minutes of baking time if starting from cold.
Freezing Instructions:
Freeze the assembled unbaked casserole wrapped tightly in foil for up to 3 months. To bake from frozen, cover with foil and bake at 375°F for 60–75 minutes, then uncover and bake until the top is golden and bubbly.
