Creating your delicious Stuffed Pepper Casserole is easy. Just follow these straightforward steps:

1. Preheat your oven to 350°F (175°C).
2. In a large skillet, brown the ground beef over medium heat, breaking it apart with a spoon until fully cooked. Drain excess fat.
3. Add the chopped onion, bell peppers, and minced garlic to the skillet. Sauté until the vegetables soften, about 5 minutes.
4. Stir in the diced tomatoes (with juice), Italian seasoning, salt, and black pepper.
5. Add the uncooked rice and beef broth to the skillet, stirring well to combine all ingredients.
6. Bring the mixture to a gentle boil. Cover with a lid, reduce heat, and simmer for about 10 minutes until rice is partially cooked.
7. Transfer the mixture to a greased 9×13-inch casserole dish, spreading evenly.
8. Cover the casserole with aluminum foil and bake in the preheated oven for 20 minutes.
9. Remove the foil, sprinkle shredded cheddar cheese on top, and bake for an additional 10-15 minutes until the cheese is bubbly and golden.
10. Once done, take the casserole out of the oven and let it sit for a few minutes before serving.
11. Adjust seasoning as necessary and garnish with fresh parsley, if desired.

Enjoying your impressive Stuffed Pepper Casserole is a breeze with these straightforward steps, ensuring a delectable meal every time.
