Tips for Success
- Cook pasta only until al dente so it doesn’t become too soft while baking
- Drain excess grease from the beef for a cleaner flavor
- Use pre-cooked rice to save time and avoid mushiness

- Let the casserole rest after baking for easier serving
- Cover with foil first to prevent the cheese from burning too quickly

Instructions
Step 1: Preheat the Oven
Preheat your oven to 375°F (190°C). Lightly grease a large 9×13-inch baking dish.
Step 2: Cook the Meat Mixture
Heat olive oil in a large skillet over medium heat. Add the ground beef and cook until browned, breaking it apart as it cooks. Drain excess fat if needed.
Add diced onion, garlic, and bell peppers. Sauté for about 4–5 minutes until softened.
Stir in diced tomatoes, marinara sauce, cooked rice, Italian seasoning, salt, pepper, and optional paprika or chili powder. Let simmer for 5–10 minutes.
Step 3: Combine with Pasta
In a large bowl, combine the cooked pasta shells with the beef and rice mixture. Stir in about 1 cup of shredded cheese.
Step 4: Assemble and Bake
Transfer the mixture into the prepared baking dish. Sprinkle the remaining cheese evenly over the top.
Cover with foil and bake for 20 minutes. Remove foil and bake an additional 10–15 minutes until the cheese is melted, bubbly, and golden.
Step 5: Rest and Serve
Allow the casserole to rest for 5–10 minutes before serving. Garnish with fresh parsley or basil if desired.
