How to Make Cheesy Stuffed Pepper Pasta Shells Casserole
Making this easy pasta casserole is simple. Prepare the pasta, cook the beef and vegetables, combine the ingredients, add the cheese, and let the oven do the rest.
Step 1: Prepare the Pasta
Preheat your oven to 375°F (190°C).
Bring a large pot of salted water to a boil. Add the large pasta shells and cook according to the package directions until just tender. Avoid overcooking them because they will continue cooking in the oven.
Drain the pasta and set it aside while you prepare the beef mixture.
Step 2: Brown the Ground Beef
Heat the olive oil in a large skillet over medium heat.
Add the ground beef and diced onion. Cook for approximately 5–7 minutes, breaking the beef into small pieces with a wooden spoon as it cooks.
Continue cooking until the beef is browned and fully cooked. If there is excessive grease in the pan, carefully drain it before moving to the next step.
Step 3: Add the Green Bell Pepper and Seasonings
Stir the diced green bell pepper into the skillet with the cooked beef.
Add the garlic powder, Italian seasoning, salt, and black pepper. Cook for another 3–4 minutes, stirring occasionally, until the pepper begins to soften.
The combination of seasoned beef, onion, and green pepper creates the savory base that gives this casserole its classic stuffed pepper flavor.
Step 4: Mix in the Rice and Tomatoes
Add the cooked rice and drained diced tomatoes to the skillet.
Stir everything together until the ingredients are evenly distributed. The rice absorbs some of the savory juices, while the tomatoes add moisture and a delicious, slightly tangy flavor.
If the mixture seems too dry, add a little beef broth or tomato sauce to help keep it moist.
Step 5: Assemble the Casserole
Lightly grease a baking dish with cooking spray or a small amount of oil.
Add the cooked pasta shells and beef mixture to the dish. Gently toss everything together, spreading the ingredients evenly throughout the casserole.
Sprinkle the shredded mozzarella cheese over the top, making sure to cover the surface generously.
Step 6: Bake Until Golden and Bubbly
Cover the baking dish with aluminum foil and bake for 20 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the mozzarella is melted, bubbling, and lightly golden around the edges.
For an extra-golden cheese topping, you can briefly place the casserole under the broiler, watching it carefully to prevent burning.
Step 7: Rest and Serve
Remove the casserole from the oven and let it rest for about 5 minutes before serving.
This short resting period helps the ingredients settle and makes serving easier.
Scoop generous portions onto plates and enjoy the combination of tender pasta, seasoned ground beef, green peppers, tomatoes, rice, and stretchy melted mozzarella.
Serve it while warm for the ultimate comfort food experience!
Tips for the Best Stuffed Pepper Pasta Casserole
A few simple tips can help you get the best results every time you prepare this cheesy ground beef casserole.
Don’t Overcook the Pasta: Cook the pasta shells until just tender. Slightly firm pasta holds its shape better during baking.
Drain Excess Grease: Depending on the fat content of your ground beef, you may need to drain excess grease after browning it. This prevents the casserole from becoming oily.
Keep the Filling Moist: If the beef, rice, and tomato mixture looks dry before baking, add a little beef broth or tomato sauce. This helps the ingredients stay moist as the casserole cooks.
Use Freshly Shredded Cheese: Freshly shredded mozzarella melts beautifully and creates a gooey, cheesy topping.
Let It Rest Before Serving: Allowing the casserole to rest for a few minutes makes it easier to scoop and serve.
Adjust the Seasonings: Taste the beef mixture before assembling the casserole and adjust the salt, pepper, garlic powder, or Italian seasoning to suit your preferences.
What to Serve With Stuffed Pepper Pasta Casserole
This hearty casserole can easily stand on its own, but a few simple side dishes can turn it into a complete family dinner.
Garlic Bread: Serve warm garlic bread alongside the casserole to soak up the flavorful tomato juices and melted cheese.
Fresh Green Salad: A crisp salad with lettuce, cucumber, tomatoes, and a light dressing provides a refreshing contrast to the rich casserole.
Roasted Vegetables: Roasted broccoli, carrots, or green beans make excellent vegetable sides.
Steamed Green Beans: Lightly seasoned green beans are an easy side dish that complements the savory ground beef.
Dinner Rolls: Soft dinner rolls are perfect for a cozy family meal.
Easy Variations to Try
One of the great things about this stuffed pepper pasta casserole is how easily you can customize it.
Use Different Cheese
Mozzarella creates a classic stretchy topping, but you can combine it with cheddar for a richer flavor. Monterey Jack is another delicious option.
Add More Vegetables
If you want to include more vegetables, try adding diced red bell peppers, mushrooms, or zucchini to the beef mixture.
Make It Spicier
Add a pinch of red pepper flakes or a little diced jalapeño if you prefer a spicy casserole.
Try Ground Turkey
Ground turkey can replace ground beef for a different flavor. Cook it thoroughly before combining it with the vegetables, rice, and tomatoes.
Add Extra Tomato Flavor
For a saucier casserole, mix in a little additional tomato sauce before transferring everything to the baking dish.
How to Store Leftovers
If you have leftovers, this cheesy stuffed pepper pasta casserole is easy to store for another meal.
Refrigerator: Allow the casserole to cool slightly, then transfer leftovers to an airtight container. Refrigerate within two hours of cooking and enjoy within 3–4 days.
Freezer: Place cooled portions in freezer-safe containers and freeze for up to 2–3 months for best quality.
Reheating: Reheat individual portions in the microwave until steaming hot throughout. You can also reheat the casserole in an oven-safe dish at 350°F (175°C), covered with foil, until heated through. Add a splash of broth or tomato sauce if it seems dry.
For food safety, reheat leftovers to an internal temperature of 165°F (74°C).
Frequently Asked Questions
Can I Make Stuffed Pepper Pasta Casserole Ahead of Time?
Yes! You can prepare the beef, vegetable, rice, and tomato mixture ahead of time. Store it in the refrigerator, then combine it with the cooked pasta and cheese when you’re ready to assemble the casserole.
You can also assemble the dish ahead of time and refrigerate it before baking. If baking directly from the refrigerator, allow extra cooking time and make sure the center reaches a safe temperature.

Absolutely! Large pasta shells work well, but penne, rotini, or elbow macaroni can also be used. Choose a pasta shape that holds the beef mixture and sauce well.
