Step 1: Preheat Your Oven

Set your oven to 375°F (190°C). While it heats, grease a 9×13-inch baking dish with cooking spray or a bit of olive oil to prevent sticking.

Step 2: Cook the Cheese Tortellini

• Bring a large pot of salted water to a rolling boil.

• Add the tortellini and cook according to the package instructions (typically 3–5 minutes if fresh, longer if frozen).

• Drain the tortellini and set aside to cool slightly while you prepare the sauce mixture.

Pro Tip: Don’t overcook the tortellini—they’ll continue cooking in the oven, and you don’t want them mushy.

Step 3: Mix the Casserole Base

• In a large bowl, combine:

  • Cooked tortellini

  • Pizza sauce

  • Half of the shredded mozzarella

  • Sliced pepperoni

  • Italian seasoning, garlic powder, and red pepper flakes (if using)

Stir everything together until well mixed and the tortellini are evenly coated.

Step 4: Assemble the Casserole

• Pour the mixture into your prepared baking dish and spread it out evenly.

• Top with the remaining mozzarella cheese and the Italian cheese blend (if using).

Variation Idea: Layer extra pepperoni or mushrooms on top for an extra pizza-like finish.

Step 5: Bake to Perfection

• Place the casserole in the oven and bake for 20–25 minutes, or until the cheese is bubbling and golden brown.

Step 6: Cool and Serve

• Remove the casserole from the oven and let it rest for 5 minutes.

• Garnish with freshly chopped basil or parsley.

• Serve warm, ideally with garlic bread or a crisp green salad.
