Ingredients

For the Casserole

• 1 lb (450 g) ground beef

• 2 cups medium pasta shells, uncooked

• 1 cup cooked rice

• 1 green bell pepper, diced

• 1 red bell pepper, diced

• 1 small onion, finely chopped

• 2 cloves garlic, minced

• 1 can (14 oz / 400 g) diced tomatoes, drained

• ½ cup tomato sauce

• ½ cup beef broth or water

• 1 tablespoon olive oil

• 1 teaspoon Italian seasoning

• 1 teaspoon paprika

• ½ teaspoon salt, or to taste

• ½ teaspoon black pepper

• 1½ cups shredded mozzarella cheese

• ½ cup shredded cheddar cheese, optional

• 1 tablespoon chopped fresh parsley, optional

Instructions

Step 1: Cook the Pasta Shells

Bring a large pot of salted water to a boil. Add the pasta shells and cook according to the package instructions until al dente, meaning they are tender but still slightly firm.

Drain the pasta thoroughly and set it aside. Avoid overcooking the shells because they will spend additional time in the oven. Slightly firm pasta holds its shape better and helps prevent the finished casserole from becoming mushy.

Step 2: Brown the Ground Beef

Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and chopped onion.

Cook for approximately 6–8 minutes, breaking the beef into small pieces with a wooden spoon or spatula. Continue cooking until the beef is browned and the onion begins to soften.

If there is excessive grease in the skillet, carefully drain it before continuing. Return the skillet to the heat.

Step 3: Add Garlic and Bell Peppers

Stir in the minced garlic and cook for approximately 30 seconds, until fragrant.

Add the diced green and red bell peppers along with the drained diced tomatoes. Cook for 3–4 minutes, stirring occasionally, until the vegetables begin to soften.

The peppers add color, flavor, and texture, while the tomatoes provide moisture and a pleasant tanginess.

Step 4: Season the Beef Mixture

Add the Italian seasoning, paprika, salt, and black pepper. Stir thoroughly so the seasonings coat the beef and vegetables evenly.

Taste the mixture and adjust the seasoning if necessary. If your beef broth or tomato sauce contains added salt, you may want to use less salt initially.

Step 5: Combine the Rice and Pasta

Add the cooked rice, drained pasta shells, tomato sauce, and beef broth to the skillet.

Stir gently until the beef, vegetables, rice, and pasta are evenly distributed. Allow the mixture to simmer for 2–3 minutes so the flavors blend together.

If the mixture looks too dry, add a small splash of broth or water. It should be moist but not watery, as excess liquid can make the casserole loose after baking.

Step 6: Prepare the Baking Dish

Preheat the oven to 375°F (190°C).

Lightly grease a medium baking dish with cooking spray or a little olive oil. Transfer the beef, rice, and pasta mixture into the dish, spreading it evenly with a spoon.

Sprinkle the shredded mozzarella cheese across the top. Add the cheddar cheese if desired for a richer flavor and extra cheesy finish.

Step 7: Bake Until Golden and Bubbly

Place the baking dish in the preheated oven and bake uncovered for 10–15 minutes, or until the cheese has melted completely and the casserole is bubbling around the edges.

For a more golden top, switch on the broiler for 1–2 minutes, watching carefully to prevent the cheese from burning.

Because the beef mixture is already cooked before baking, the oven step primarily heats everything through and melts the cheese. Make sure the casserole is hot throughout before serving.

Step 8: Rest and Serve

Remove the casserole from the oven and let it rest for approximately 5 minutes. This helps the mixture settle slightly and makes serving easier.

Sprinkle with chopped fresh parsley if desired. Spoon generous portions onto plates and serve warm while the mozzarella is stretchy and the cheddar is deliciously melted.

Recipe Notes

• Ground beef: Lean ground beef works well and reduces excess grease.

• Pasta shells: Medium shells hold the sauce nicely, but elbow macaroni or rotini can also be used.

• Cooked rice: Use previously cooked rice that has been stored safely. Do not leave cooked rice at room temperature for extended periods.

• Tomatoes: Drain canned tomatoes to avoid adding too much liquid.

• Cheese: Mozzarella gives a stretchy texture, while cheddar adds a stronger flavor.

• Broth: Beef broth adds savory depth; water is a suitable budget-friendly substitute.

• Vegetables: Mushrooms, zucchini, or corn can be added if desired.

• Seasoning: Adjust salt, pepper, and paprika according to taste.

Tips for the Best Casserole

1. Cook the pasta just until al dente to prevent it from becoming too soft.

2. Brown the beef thoroughly for a richer, savory flavor.

3. Drain excess grease before adding the vegetables.

4. Use freshly shredded cheese for a smooth melt.

5. Make sure the rice is fully cooked before adding it.

6. Avoid adding too much broth, which can make the casserole watery.

7. Spread the cheese evenly for a consistent topping.

8. Watch closely if broiling because cheese can brown quickly.

9. Let the casserole rest before serving.

10. Garnish with fresh parsley for extra color and freshness.

Serving Suggestions

This casserole is satisfying on its own, but a few simple sides can make the meal even better.

• Fresh garden salad with lemon dressing

• Steamed broccoli

• Roasted green beans

• Garlic bread

• Roasted carrots

• Sautéed zucchini

• Cucumber and tomato salad

• Steamed mixed vegetables

For a balanced plate, serve a moderate portion of casserole alongside a generous serving of vegetables.

Storage and Reheating

Refrigeration: Allow leftovers to cool slightly and refrigerate them in airtight containers within two hours of cooking. Consume within 3–4 days.

Freezing: Divide the cooled casserole into freezer-safe portions and freeze for up to 2–3 months for best quality. The pasta texture may soften slightly after thawing.

Oven reheating: Place the casserole in an oven-safe dish, cover with foil, and reheat at 350°F (175°C) until hot throughout. Add a small splash of broth if it appears dry.

Microwave reheating: Place an individual portion in a microwave-safe bowl and cover loosely. Heat in short intervals, stirring if possible, until evenly hot.

Reheat leftovers to 165°F (74°C). Refrigerate cooked rice promptly and avoid leaving the casserole at room temperature for extended periods.
