Cook the pasta a la dente according to the package directions; drain and set aside.
Preheat your oven to 350° F and grease a 9x13 baking dish.
In a large skillet, brown the ground beef with your choice of seasonings.
Remove any excess grease from the browned beef and then stir in your tomato sauce along with cubed cream cheese.
Gently toss your cooked tortellini into the sauce mixture before pouring it all into your prepared casserole dish.
Bake uncovered in the center rack of your oven for about 20 minutes.
Enjoy your delicious Cheesy Baked Tortellini Casserole alone or with sides like salad, veggies, or garlic bread!
