Rolling up your sleeves and diving into this Stuffed Pepper Casserole is easy, thanks to a straightforward sequence of steps. From sizzling aromatic veggies in a skillet to layering rich cheeses in a baking dish, each phase builds flavor and texture. Follow along as we break down the process into clear, manageable actions—no culinary degree required!
1. Preheat your oven to 375°F (190°C) and position a rack in the center to ensure even baking.
2. In a large skillet, heat the olive oil over medium heat. Add the chopped onion and minced garlic, sautéing until the onion turns translucent, about 3–4 minutes, stirring occasionally.
3. Add the lean ground beef to the skillet. Use a wooden spoon to break it apart and cook until fully browned, roughly 5–7 minutes. Drain any excess fat to keep the casserole from becoming greasy.
4. Stir in the diced bell peppers and continue cooking for another 3–4 minutes, until they begin to soften and release their sweet aroma.
5. Add the cooked rice, diced tomatoes with their juices, tomato sauce, Italian seasoning, salt, and black pepper. Stir well to combine, ensuring every grain of rice and piece of meat is coated.
6. Simmer the mixture on low heat for 10 minutes, allowing flavors to meld. Stir occasionally to prevent sticking and encourage even cooking.
7. Remove the skillet from heat and stir in 1 cup of the mozzarella cheese, letting it melt into the warm filling.
8. Transfer the cheesy mixture into a greased 9x13-inch baking dish, using a spatula to spread it evenly.
9. Sprinkle the top with the remaining 1 cup of mozzarella cheese and 1 cup of cheddar cheese, creating a generous, bubbly layer.
10. Cover the dish with aluminum foil and bake for 20 minutes, trapping steam to keep the casserole moist.
11. After 20 minutes, remove the foil and bake an additional 10 minutes, or until the cheese is bubbling and beginning to brown at the edges.
12. Remove from the oven and allow the casserole to sit for about 5 minutes to set, making it easier to serve.
13. Garnish with freshly chopped parsley, if desired, before slicing into squares and serving.
