• 1 1/2 cups cooked white rice
• 1 medium onion, finely chopped
• 1 green bell pepper, diced
• 1 red bell pepper, diced
• 3 garlic cloves, minced
• 1 can (14.5 ounces) diced tomatoes, with juices
• 1 cup tomato sauce
• 1 teaspoon Italian seasoning
• 1 teaspoon paprika
• 1/2 teaspoon garlic powder
• 1/2 teaspoon salt, or to taste

How to Make Cheesy Ground Beef, Rice and Pasta Casserole

Step 1: Cook the Pasta

Bring a large pot of salted water to a boil. Add the pasta shells and cook for approximately 1–2 minutes less than the package instructions recommend. The pasta should be slightly firm because it will continue cooking in the oven.

Drain well and set aside.

Step 2: Brown the Ground Beef

Heat the olive oil in a large skillet over medium-high heat. Add the ground beef and cook for 6–8 minutes, breaking it into small crumbles with a wooden spoon.

Continue cooking until the beef is fully browned and no pink remains. Drain excess grease if necessary.

Step 3: Add the Vegetables

Add the chopped onion, green bell pepper, and red bell pepper to the skillet. Cook for approximately 4–5 minutes, stirring occasionally, until the vegetables begin to soften.

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

Step 4: Build the Flavorful Sauce

Add the diced tomatoes, tomato sauce, Italian seasoning, paprika, garlic powder, salt, and black pepper.

Stir thoroughly and allow the mixture to simmer gently for 5–7 minutes. If the sauce becomes too thick, add a little beef broth to maintain a moist consistency.

Step 5: Combine the Rice and Pasta

Preheat your oven to 375°F (190°C).

Transfer the cooked pasta shells and rice into a large mixing bowl. Add the seasoned beef and vegetable mixture, then gently stir until everything is evenly coated.

Fold in half of the cheddar cheese and approximately half a cup of mozzarella for extra creaminess.

Step 6: Assemble the Casserole

Lightly grease a 9x13-inch baking dish. Spoon the beef, rice, and pasta mixture into the dish and spread it evenly.

Sprinkle the remaining mozzarella and cheddar over the top, covering the casserole with a generous layer of cheese.

Step 7: Bake Until Golden

Cover the baking dish loosely with aluminum foil and bake for 15 minutes. Remove the foil and continue baking for another 10–15 minutes, until the cheese is melted, lightly golden, and the casserole is bubbling around the edges.

The center should reach 165°F (74°C) before serving.

Step 8: Rest and Serve

Remove the casserole from the oven and let it rest for approximately 5 minutes. Garnish with chopped fresh parsley if desired.

Serve warm while the cheese is deliciously melted and stretchy.

Helpful Cooking Tips

• Undercook the pasta slightly: This prevents the shells from becoming mushy during baking.
• Use cooked rice: Uncooked rice will not cook properly with the liquid amounts in this recipe.
• Keep the filling moist: Add a splash of broth if the mixture appears dry before baking.
• Shred your own cheese: Freshly shredded cheese often melts more smoothly.
• Let the casserole rest: A few minutes of resting helps the portions hold together.

Easy Recipe Variations

Spicy Southwest Version

Add diced jalapeños, chili powder, and a pinch of cumin. Replace the mozzarella with Monterey Jack or pepper jack cheese.

Italian-Inspired Casserole

Use marinara sauce instead of plain tomato sauce and add extra oregano, basil, and Parmesan cheese.

Extra Vegetable Version

Mix in sautéed mushrooms, zucchini, spinach, or finely chopped carrots for additional vegetables.

Ground Turkey Alternative

Substitute lean ground turkey for beef and cook it thoroughly to 165°F (74°C) before assembling the casserole.

What to Serve with This Casserole

Because this recipe already includes protein, rice, and pasta, lighter side dishes work particularly well.

• Fresh garden salad with vinaigrette
• Steamed broccoli or green beans
• Roasted zucchini
• Garlic bread
• Cucumber and tomato salad

Storage and Reheating

Refrigerator

Transfer leftovers into airtight containers and refrigerate within two hours of cooking. Store for up to 3–4 days.

Freezer

Allow the casserole to cool, divide it into freezer-safe portions, and freeze for up to 2–3 months for the best quality.

Reheating

Reheat individual servings in the microwave or warm larger portions in a covered baking dish at 350°F (175°C). Add a small splash of broth or water if needed and heat until the center reaches 165°F (74°C).

Frequently Asked Questions

Can I make this casserole ahead of time?

Yes. Assemble the casserole, cover tightly, and refrigerate for up to 24 hours before baking. Allow a little additional baking time if it goes into the oven cold.

Can I use brown rice?

Absolutely. Fully cooked brown rice adds a slightly nutty flavor and firmer texture.

What pasta shapes work best?

Medium shells, elbow macaroni, rotini, and small penne are excellent choices because they hold the sauce and blend easily with the rice.

How can I make the casserole creamier?

Stir in 2–3 tablespoons of cream cheese or a splash of heavy cream before baking for a richer texture.

Can I leave out the rice?

Yes, although the dish will have a different texture. You can replace the rice with additional cooked pasta and adjust the sauce as needed.
