### Step-by-Step Instructions
#### Prepare the Tortellini
Preheat your oven to 375°F (190°C). Grease a 9x13-inch baking dish.
Cook the tortellini according to the package instructions. Drain and set aside.
#### Make the Meat Sauce
In a large skillet, cook the ground beef or turkey over medium heat until browned. Drain any excess fat.
Stir in the marinara sauce, garlic powder, onion powder, and Italian seasoning. Simmer for 5–7 minutes.
#### Prepare the Cream Cheese Mixture
In a mixing bowl, combine the cream cheese, sour cream, and Parmesan cheese. Mix until smooth.
#### Assemble the Casserole
Spread half of the meat sauce in the bottom of the prepared baking dish.
Layer half of the cooked tortellini on top of the sauce.
Spread the cream cheese mixture over the tortellini, followed by the remaining tortellini and meat sauce.
Sprinkle the shredded mozzarella evenly over the top.
#### Bake the Casserole
Cover the dish with foil and bake for 20 minutes.
Remove the foil and bake for an additional 10–15 minutes, or until the cheese is golden and bubbly.
#### Serve
Remove from the oven and let the casserole rest for 5 minutes before serving.
