Creating Easy One-Pan Beefy Tortellini Bake is straightforward if you follow these steps:

1. Preheat Oven: Preheat your oven to 375°F (190°C).
2. Cook the Beef: In a large oven-safe skillet, brown the ground beef over medium heat. Break it apart with a spatula until it’s fully cooked and no longer pink.
3. Add Onions and Garlic: Stir in the chopped onion and minced garlic. Cook for 3-4 minutes until the onion becomes translucent.
4. Combine Tomatoes and Broth: Add the diced tomatoes (with juice), beef broth, marinara sauce, Italian seasoning, salt, and pepper to the skillet. Stir well.
5. Incorporate Tortellini: Add the cheese tortellini to the mixture, ensuring they are fully submerged in the sauce.
6. Simmer: Allow the mixture to simmer on medium heat for about 5 minutes, letting the tortellini absorb the flavors.
7. Top with Cheese: Sprinkle shredded mozzarella cheese evenly over the top of the tortellini mixture.
8. Bake: Transfer the skillet to the preheated oven and bake for 15-20 minutes, or until the cheese is bubbly and golden brown.
9. Garnish: Remove from the oven and sprinkle fresh basil on top if desired for an extra pop of flavor.

By following these steps, you’ll have a delicious and filling Easy One-Pan Beefy Tortellini Bake that’s perfect for any meal occasion!
