Stuffed Pepper Casserole is a hearty, one-pan comfort dish that captures all the flavors of classic stuffed peppers — tender rice, savory ground meat, and sweet bell peppers simmered in a rich tomato sauce, topped with melted cheese. It’s easy, family-friendly, and perfect for busy weeknights.

Ingredients

  • 2 tbsp olive oil
  • 1 lb ground beef, turkey, or plant-based ground “meat”
  • 1 yellow onion, diced
  • 3 garlic cloves, minced
  • 3 bell peppers (red, green, yellow), chopped
  • 2 cups cooked rice (white, brown, or long-grain)
  • 1 can (15 oz) tomato sauce or crushed tomatoes
  • 1 can (14 oz) diced tomatoes (optional)
  • 2 tbsp tomato paste
  • 1 tbsp Italian seasoning
  • 1 tsp paprika
  • Salt and black pepper to taste
  • 1 cup shredded cheese (cheddar, mozzarella, or vegan alternative)
  • 2 tbsp chopped fresh parsley (for garnish)

Instructions

  1. Preheat the oven: Set oven to 375°F (190°C).
  2. Cook the base: In a large skillet or oven-safe pan, heat olive oil over medium heat. Add onion and garlic; sauté until fragrant.
  3. Add meat: Stir in ground beef or alternative and cook until browned. Drain any excess fat.
  4. Add vegetables and seasoning: Mix in chopped bell peppers, Italian seasoning, paprika, salt, and pepper. Cook for about 5 minutes until peppers start to soften.
  5. Combine with rice and sauce: Stir in cooked rice, tomato sauce, diced tomatoes, and tomato paste. Mix until evenly combined and heated through.
  6. Transfer to baking dish: If not using an oven-safe skillet, transfer the mixture to a greased casserole dish.
  7. Top with cheese: Sprinkle shredded cheese evenly on top.
  8. Bake: Bake for 20–25 minutes, until the cheese is melted and bubbly.
  9. Serve: Garnish with fresh parsley and serve warm.

Notes

  • Use cooked rice to save time, or add uncooked rice with 1½ cups broth and extend baking time.
  • Make it vegan with plant-based meat and dairy-free cheese.
  • To freeze, cool completely, wrap tightly, and store for up to 2 months.
  • For extra creaminess, mix cheese into the casserole before baking.
  • Double the recipe for a crowd and bake in a 9×13-inch dish.
