Marinara sauce: Tomato sauce keeps the pasta moist and adds classic Italian-American flavor.

Ingredients
- 20–24 jumbo pasta shells
- 1 pound lean ground beef
- 1 tablespoon olive oil
- 1 small yellow onion, finely diced
- 3 cloves garlic, minced
- 1 teaspoon Italian seasoning
- ½ teaspoon dried oregano
- ½ teaspoon salt
- ¼ teaspoon black pepper
- ¼ teaspoon crushed red pepper flakes, optional
- 1½ cups ricotta cheese
- ½ cup grated Parmesan cheese
- 1 large egg
- 3 cups marinara sauce
- 2 cups shredded mozzarella cheese
- 2 tablespoons chopped fresh parsley
How to Choose the Best Ingredients
Choose jumbo shells that are large enough to hold several spoonfuls of filling. Cook a few extra because occasionally a shell can tear during boiling.
An 85–90% lean ground beef works particularly well. It has enough fat for good flavor without leaving the casserole greasy.
Use a thick marinara sauce rather than a watery pasta sauce. A thicker sauce stays around the shells and creates a richer finished casserole.
Whole-milk ricotta produces the creamiest filling, while freshly shredded mozzarella generally melts more smoothly than pre-shredded cheese.
Prepare the Pasta Shells
Bring a large pot of salted water to a boil.
Add the jumbo shells and cook them approximately 2 minutes less than the package directions. They should be flexible but still slightly firm because they will continue cooking in the oven.
Drain carefully and rinse briefly with cool water.
Arrange the shells separately on a baking sheet or clean surface so they do not stick together.
Prepare the Beef Filling
Heat the olive oil in a large skillet over medium heat.
Add the diced onion and cook for 3–4 minutes until softened.
Add the ground beef and break it into small pieces with a wooden spoon.
Cook until browned and no longer pink.
Drain excess grease if necessary.
Add the garlic, Italian seasoning, oregano, salt, black pepper, and optional red pepper flakes.
Cook for another minute until fragrant.
Remove from the heat and allow the beef to cool slightly.
In a large bowl, combine the ricotta, Parmesan, egg, and approximately 1 cup of the cooked beef mixture.
Fold everything together until evenly combined.
You can also reserve some beef to spoon over the shells before adding the mozzarella.
Step-by-Step Instructions
- Preheat the oven to 375°F.
- Spread approximately 1½ cups of marinara sauce evenly across the bottom of a 9×13-inch baking dish.
- Carefully open each cooked jumbo shell.
- Fill each shell generously with the beef and ricotta mixture.
- Arrange the stuffed shells side by side over the marinara sauce with the openings facing upward.
- Spoon the remaining cooked beef around and over the shells.
- Spoon the remaining marinara sauce around the shells, leaving some of the filling visible.
- Sprinkle the mozzarella evenly over the entire casserole.
- Add a little additional Parmesan if desired.
- Cover loosely with aluminum foil and bake for approximately 20 minutes.
- Remove the foil and bake for another 8–10 minutes until the cheese is completely melted and lightly golden.
- For additional browning, broil for 1–2 minutes while watching carefully.
- Remove from the oven and allow the casserole to rest for 5–10 minutes.
- Sprinkle with fresh parsley and serve warm.
Tips for Best Results
Do not overcook the pasta shells during boiling. Slightly undercooked shells are easier to fill and less likely to tear.
Cook several extra shells in case a few break.
Drain excess grease from the beef before preparing the filling. Too much fat can make the casserole oily.
Keep enough marinara sauce underneath the pasta. This prevents the bottoms of the shells from drying out during baking.
Do not pack the filling excessively tightly. A generous but loose filling creates a better texture.
Allow the casserole to rest briefly after baking. This helps the cheese and sauce settle and makes serving easier.
Flavor Variations
For Italian sausage stuffed shells, replace half or all of the ground beef with mild Italian sausage.
For extra cheesy shells, add shredded mozzarella directly to the beef and ricotta filling.
For spinach beef stuffed shells, fold 1 cup of chopped cooked spinach into the cheese mixture.
For a spicy version, increase the crushed red pepper and use spicy marinara sauce.
For a three-cheese version, combine ricotta, mozzarella, and Parmesan inside each shell before adding the final mozzarella topping.
How to Serve
Serve Cheesy Beef Stuffed Shells hot from the oven with extra marinara sauce available at the table.
Garlic bread is an excellent side because it can soak up the tomato and cheese sauce left on the plate.
A simple Caesar salad, garden salad, roasted broccoli, green beans, or sautéed zucchini can balance the richness of the pasta.
For a family dinner, approximately 3–4 stuffed shells per person usually makes a satisfying serving.
Meal Prep & Storage
This casserole is excellent for meal prep.
Assemble the stuffed shells completely, cover the baking dish tightly, and refrigerate for up to 24 hours before baking.
When baking directly from the refrigerator, allow approximately 5–10 additional minutes of covered baking time.
Store cooked leftovers in an airtight container in the refrigerator for up to 4 days.
Individual portions can be reheated in the microwave, while larger portions reheat well in a covered baking dish at 350°F.
The assembled casserole can also be frozen. Wrap it tightly and freeze for up to 2 months.
Common Mistakes to Avoid
Do not boil the shells until extremely soft. They can tear while filling and become mushy after baking.
Avoid using extremely watery marinara sauce because it can make the bottom of the casserole soupy.
Do not skip draining excess beef fat.
Make sure there is sauce underneath the shells before baking.
Finally, avoid baking uncovered for the entire cooking time because the cheese can brown before the pasta and filling are thoroughly heated.
FAQ
Can I make stuffed shells ahead of time?
Yes. Assemble them up to 24 hours ahead, cover tightly, and refrigerate until ready to bake.

Yes. Ground turkey or chicken can replace the beef.

Yes. Cottage cheese can be substituted, although the texture will be slightly different.
Why did my pasta shells tear?
They were probably overcooked. Cook them slightly less than the package directions and handle them gently.
Can stuffed shells be frozen?
Yes. They freeze particularly well before baking and can be stored for approximately 2 months.
How do I get the browned cheese shown on top?
Bake until the mozzarella is melted, then broil briefly for 1–2 minutes. Watch closely because cheese can brown very quickly.
