· 2 green bell peppers, diced
· 1 red bell pepper, diced (optional, for color)
· 3 cloves garlic, minced
· 1 can (14.5 oz) diced tomatoes, undrained
· 1 can (8 oz) tomato sauce
· 2 cups beef broth
· 1 cup uncooked long-grain white rice
· 1 cup uncooked medium pasta shells
· 2 cups shredded sharp cheddar cheese (or mozzarella)
· 1 teaspoon Italian seasoning
· 1 teaspoon smoked paprika
· 1 teaspoon salt
· ½ teaspoon black pepper
· 1 tablespoon olive oil
Optional add-ins: 1 can (15 oz) drained corn, 1 can (15 oz) drained black beans, 1 diced jalapeño for heat, ½ teaspoon red pepper flakes, 1 teaspoon garlic powder, 1 tablespoon Worcestershire sauce, ½ cup grated Parmesan cheese.
Note: For a gluten-free version, use gluten-free pasta and ensure beef broth is gluten-free. For a lower-carb option, replace rice with cauliflower rice and pasta with zucchini noodles. Ground turkey or chicken can be substituted for ground beef.
Step-by-Step Instructions
- Preheat and Prepare: Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish with cooking spray or a little oil.
- Brown the Beef and Vegetables: Heat the olive oil in a large skillet over medium-high heat. Add the ground beef, diced onion, and diced bell peppers. Cook until the beef is browned and the vegetables are softened, about 6-8 minutes. Break up the beef with a wooden spoon as it cooks. Drain any excess fat.
- Add Garlic: Add the minced garlic to the skillet and sauté for 1 minute until fragrant. Don’t let the garlic burn—it should just become aromatic.
- Add Liquids and Starches: Stir in the diced tomatoes (with their juices), tomato sauce, beef broth, uncooked rice, uncooked pasta shells, Italian seasoning, smoked paprika, salt, and black pepper. Mix well to combine. Make sure the rice and pasta are evenly distributed.
- Transfer to Baking Dish: Transfer the mixture to the prepared baking dish. Cover tightly with aluminum foil. The foil traps steam, which cooks the rice and pasta perfectly.
- Bake Covered: Bake for 45 minutes. The rice and pasta will absorb the liquid and become tender.
- Add Cheese: Remove the foil and stir the casserole gently to ensure even cooking. Sprinkle the shredded cheese evenly over the top.
- Bake Uncovered: Bake uncovered for an additional 10-15 minutes, until the cheese is completely melted, bubbly, and lightly browned, and the rice and pasta are tender.
- Rest and Serve: Let it rest for 5 minutes before serving. This allows the casserole to set slightly and makes serving easier. Serve hot and enjoy every cheesy, savory bite.
Tips for the Best Cheesy Beef & Pepper Pasta Bake
· Use Long-Grain White Rice: Jasmine or basmati rice works well. Avoid instant rice, which cooks too quickly and becomes mushy. Brown rice requires a longer cooking time and more liquid.
· Don’t Overcook the Pasta: The pasta will continue to cook in the oven. Use uncooked pasta shells—they’ll absorb the liquid and become perfectly tender.
· Cover Tightly with Foil: The foil traps steam, which is essential for cooking the rice and pasta evenly. Don’t skip this step.
· Stir Gently: When removing the foil, stir gently to redistribute the rice and pasta. This ensures even cooking and prevents sticking.
· Use Freshly Shredded Cheese: Pre-shredded cheese contains anti-caking agents that prevent smooth melting. Freshly shredded sharp cheddar melts beautifully and adds superior flavor.
· Let It Rest: The 5-minute rest allows the casserole to set and the flavors to meld together.
· Adjust Consistency: If the casserole seems dry after baking, add a splash of beef broth. If too wet, bake uncovered for a few extra minutes.
Variations & Substitutions
· Mexican-Inspired Version: Add 1 can drained black beans, 1 can drained corn, and 1 teaspoon cumin. Use pepper jack cheese and top with cilantro.
· Italian Version: Use Italian sausage instead of ground beef. Add 1 teaspoon dried oregano and ½ teaspoon dried basil. Use mozzarella and Parmesan cheese.
· Spicy Version: Add 1 diced jalapeño, ½ teaspoon red pepper flakes, and use pepper jack cheese.
· Vegetarian Version: Replace ground beef with plant-based crumbles or extra beans. Use vegetable broth instead of beef broth.
· Chicken Version: Substitute ground chicken or shredded cooked chicken for the beef.
· Low-Carb Version: Replace rice with cauliflower rice and pasta with zucchini noodles. Reduce broth to 1 cup.
Make-Ahead and Freezer Instructions
· Make-Ahead: Assemble the casserole completely (without baking), cover tightly with plastic wrap, and refrigerate for up to 24 hours. When ready to bake, let it sit at room temperature for 15 minutes, then bake as directed, adding 10-15 minutes to the covered baking time.
· Freezer Method: Assemble the casserole in a freezer-safe dish. Cover tightly with plastic wrap and foil, then freeze for up to 3 months. Thaw overnight in the refrigerator, then bake as directed. You can also freeze baked leftovers—let them cool completely, then wrap and freeze. Reheat in a 350°F oven until hot.
Frequently Asked Questions
Can I use a different type of pasta?
Yes! Any small pasta shape works well—elbow macaroni, rotini, penne, or farfalle. Adjust cooking time based on the pasta shape. Smaller shapes cook faster.
Can I use brown rice instead of white rice?
Brown rice requires a longer cooking time and more liquid. If using brown rice, increase the beef broth to 2 ½ cups and bake covered for 60 minutes before adding the cheese.
Why is my casserole dry?
This usually means there wasn’t enough liquid or the casserole baked too long. Make sure to use the full amount of beef broth and cover tightly with foil. If it seems dry after baking, add a splash of broth.
Why is my casserole mushy?
Mushy casserole usually means too much liquid was used or it baked too long. Use exactly the recommended amount of broth and check at the minimum baking time. The rice and pasta should be tender but not overcooked.
How do I store leftovers?
Store in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or reheat the entire dish in a 350°F oven until hot.
Can I freeze this casserole?
Yes! Freeze unbaked or baked casserole for up to 3 months. Thaw overnight in the refrigerator, then bake as directed. Baked leftovers can be frozen and reheated in the oven.
Can I make this in a slow cooker?
Yes! Brown the beef and vegetables on the stovetop, then transfer to a slow cooker with all remaining ingredients except cheese. Cook on LOW for 4-5 hours, then sprinkle cheese on top during the last 15 minutes.
What can I serve with this casserole?
This casserole is a complete meal on its own, but a simple green salad, garlic bread, or roasted vegetables pair beautifully. For a lighter side, serve with steamed broccoli or a cucumber tomato salad.
