Bring a large pot of salted water to a boil. Add the 9 ounces of cheese tortellini and cook according to package instructions, usually about 3-5 minutes until al dente. Drain well and set aside.
In a large skillet or saucepan, heat 1 tablespoon of olive oil over medium heat. Pour in 1 cup of heavy cream and bring it to a gentle simmer. Gradually stir in 1/2 cup grated Parmesan cheese, 1/2 cup shredded mozzarella, and 1/2 cup ricotta cheese until the cheeses melt and the sauce becomes smooth.
Add 1 teaspoon garlic powder, 1/4 teaspoon onion powder, 1/2 teaspoon black pepper, and 1/4 teaspoon salt. Stir well to incorporate all the spices evenly into the sauce.
Add the cooked chicken (1 cup diced) and 1/2 cup frozen peas directly into the Alfredo sauce. Then gently fold in the cooked tortellini, ensuring everything is coated with the creamy sauce.
Transfer the tortellini mixture into a greased 8x8-inch baking dish. Sprinkle 1/2 cup breadcrumbs evenly over the top to create a crunchy crust during baking.
Preheat your oven to 375°F (190°C). Bake the dish uncovered for 20-25 minutes, or until the top is golden brown and the sauce is bubbling around the edges.
Once baked, remove the dish from the oven and sprinkle 2 tablespoons chopped fresh parsley over the top for a fresh, vibrant finish. Serve hot and enjoy the creamy, cheesy goodness!
