  • 1 tsp olive oil (plus a little extra)
  • 1 white onion, finely diced
  • 1 large green pepper, finely diced
  • 1 red pepper, finely diced
  • A pinch of salt
  • 2 cloves of garlic, finely diced
  • 1 lb extra lean ground beef, shredded
  • 1 tbsp Italian seasoning
  • ½ tsp black pepper
  • ½ tsp red pepper flakes
  • 1 28-ounce can of diced tomatoes
  • 2 cups cooked rice (pre-cooked varieties like Uncle Ben’s can save time)
  • 1 oz soy sauce
  • 1 cup fresh grated Parmesan
  • 2 cups grated Italian mixed cheese


  1. Preheat the Oven: Start by preheating your oven to 375°F (190°C).
  2. Prepare the Vegetables: In a non-stick pan, heat 1 tsp of olive oil over medium-high heat. Add the diced onion, green pepper, and red pepper, along with a drizzle of olive oil and a pinch of salt. Cook for about 5 minutes until softened, not browned.
  3. Add Garlic: Stir in the finely diced garlic and cook for another minute to release its fragrance.
  4. Cook the Ground Beef: Add the shredded ground beef to the pan along with Italian seasoning, black pepper, and red pepper flakes. Stir constantly until all the pink has disappeared from the beef, around 5 minutes.
  5. Mix in Tomatoes and Rice: Pour in the canned diced tomatoes and stir well. Add the cooked rice (ready-made varieties work well here) and soy sauce. Mix thoroughly.
  6. Add Cheese: Stir in the fresh grated Parmesan and continue cooking for 6 minutes to reduce the moisture. Be sure not to skip this step or the casserole may become soggy.
  7. Prepare the Baking Dish: Lightly grease a 9×13 baking dish and pour the mixture into it. Spread the grated Italian mixed cheese evenly on top.
  8. Bake: Cover the dish with tin foil and place it in the preheated oven for 30 minutes.
  9. Final Touch: Remove the tin foil and bake for an additional 10 minutes, or until the cheese is golden brown.
  10. Serve and Enjoy: Once out of the oven, allow the casserole to cool slightly before serving. The tantalizing blend of soft peppers, savory beef, and golden-brown cheese will be a hit with everyone at your table!
