- Aluminum foil
Step 1: Cook the Pasta
Bring a large pot of salted water to a boil.
Cook the pasta shells until just al dente according to package instructions.
Drain and set aside.
Avoid overcooking because the pasta will continue cooking in the oven.
Step 2: Prepare the Rice
Cook rice according to package instructions.
You can also use leftover rice.
Allow it to cool slightly before mixing into the casserole.
Step 3: Brown the Beef
Heat olive oil in a large skillet.
Add:
- Ground beef
- Onion
Cook over medium-high heat for 6–8 minutes.
Break the beef apart as it cooks.
Continue until the meat is browned and onions are softened.
Drain excess grease if necessary.
Step 4: Add Vegetables
Add:
- Green bell pepper
- Red bell pepper
- Garlic
Cook for another 3–4 minutes.
The vegetables should soften slightly while retaining some texture.
Step 5: Build the Flavor Base
Stir in:
- Diced tomatoes
- Tomato paste
- Italian seasoning
- Paprika
- Salt
- Black pepper
Cook for 5 minutes.
This allows the flavors to blend beautifully.
The mixture should become rich and aromatic.
Step 6: Combine Everything
In a large bowl combine:
- Cooked pasta shells
- Cooked rice
- Beef mixture
Mix gently until evenly distributed.
At this stage, every spoonful should contain pasta, rice, vegetables, and beef.
Step 7: First Layer of Cheese
Add:
- 1 cup mozzarella
- ½ cup cheddar
Mix into the casserole.
This creates pockets of melted cheese throughout the dish.
Step 8: Transfer to Baking Dish
Lightly grease a 9×13-inch baking dish.
Spread the mixture evenly.
Press gently with a spoon to create an even layer.
Step 9: Add the Cheese Topping
Sprinkle evenly over the top:
- Remaining mozzarella
- Remaining cheddar
- Parmesan
The thick layer of cheese will become golden and bubbly during baking.
Step 10: Bake
Preheat oven to 375°F (190°C).
Cover with foil.
Bake for 20 minutes.
Remove foil and continue baking for another 10–15 minutes.
