Step-by-Step Instructions to Make Stuffed Pepper Casserole
- Sauté Veggies
In a large oven-safe skillet, heat olive oil. Add chopped onions and bell peppers. Sauté until softened, about 5 minutes. - Brown the Meat
Stir in the ground beef or turkey. Cook until fully browned. Drain excess fat if needed. - Add Garlic & Seasonings
Stir in minced garlic, Italian seasoning, smoked paprika, salt, and pepper. Cook for 30 seconds to bloom the flavors. - Stir in Tomatoes & Rice
Add diced tomatoes, tomato sauce, and uncooked rice. Stir to combine, then pour in broth. Bring to a gentle boil. - Simmer & Cook the Rice
Reduce heat, cover, and simmer for 20–25 minutes until rice is tender and the liquid is absorbed. - Add Cheese & Bake
Stir the mixture, sprinkle cheese evenly on top, and broil (or bake uncovered at 375°F) for 5–7 minutes until melted and bubbly. - Garnish & Serve
Sprinkle with fresh chopped parsley and serve hot. Enjoy!
Expert Tip: To avoid mushy rice, don’t overcook after adding broth. Keep the lid on while simmering and check for doneness at 20 minutes.
