Instructions
Step 1: Cook the Pasta Shells
Bring a large pot of generously salted water to a rolling boil.
Add the jumbo pasta shells and cook according to the package directions until al dente.
Do not overcook them because they will continue baking in the oven.
Drain carefully and rinse under cold water to stop the cooking process.
Lay the shells on a lightly oiled baking sheet or parchment paper so they don’t stick together.
Step 2: Prepare the Beef
Heat the olive oil in a large skillet over medium-high heat.
Add the diced onion and cook for 3–4 minutes, until softened.
Stir in the minced garlic and cook for another 30 seconds.
Add the ground beef.
Cook for 6–8 minutes, breaking it into small crumbles with a wooden spoon.
Once browned, drain any excess grease.
Season with:
- Italian seasoning
- Oregano
- Garlic powder
- Onion powder
- Paprika
- Salt
- Black pepper
Allow the beef mixture to cool slightly.
Step 3: Make the Cheese Filling
In a large mixing bowl combine:
- Ricotta cheese
- 1½ cups mozzarella
- Parmesan cheese
- Egg
- Chopped parsley
- Italian seasoning
Mix until smooth.
Fold the cooled ground beef into the cheese mixture.
Taste and adjust the seasoning if needed.
Step 4: Prepare the Sauce
In a saucepan combine:
- Marinara sauce
- Tomato paste
- Garlic powder
- Basil
- Red pepper flakes
Simmer gently for 5 minutes, stirring occasionally.
This helps deepen the flavor of the sauce.
Step 5: Assemble the Dish
Preheat the oven to 375°F (190°C).
Spread about 1 cup of the marinara sauce over the bottom of a 9×13-inch baking dish.
Using a spoon or cookie scoop, fill each pasta shell generously with the beef and cheese mixture.
Arrange the stuffed shells in the baking dish in a single layer.
Pour the remaining marinara sauce evenly over the shells.
Top with the remaining mozzarella cheese.
Sprinkle a little extra Parmesan over the top.
Step 6: Bake
Cover the baking dish loosely with aluminum foil.
Bake for 25 minutes.
Remove the foil and continue baking for another 10–15 minutes, or until the cheese is melted, bubbling, and lightly golden.
For an extra crispy cheese topping, broil for 2 minutes at the end.
Watch carefully to prevent burning.
Step 7: Rest
Remove the dish from the oven.
Allow it to rest for 10 minutes before serving.
This helps the filling set and makes the shells easier to serve.
Step 8: Garnish and Serve
Sprinkle with:
- Fresh parsley
- Parmesan cheese
- Fresh basil
Serve hot with garlic bread and a crisp green salad.
Helpful Tips
Cook the Shells Carefully
Slightly undercook the shells so they remain sturdy enough to fill without tearing.
Cool the Beef
Allow the beef to cool before mixing it with the cheese to prevent the egg from cooking prematurely.
Use Freshly Grated Cheese
Fresh mozzarella and Parmesan melt more smoothly and provide better flavor than pre-shredded cheese.
Don’t Overfill the Baking Dish
Arrange the shells in a single layer so they heat evenly and the sauce reaches every shell.

Italian Sausage Shells
Replace half of the ground beef with Italian sausage for extra flavor.
