Ingredients
24 jumbo pasta shells
1 pound ground beef
1 tablespoon olive oil
1 small yellow onion, finely diced
3 cloves garlic, minced
3 cups marinara sauce, divided
1 cup ricotta cheese
1 1/2 cups shredded mozzarella cheese, divided
1/2 cup grated Parmesan cheese
1 large egg
1 teaspoon Italian seasoning

1/2 teaspoon onion powder
1/2 teaspoon black pepper
1/2 teaspoon salt, divided
1/4 teaspoon crushed red pepper flakes, optional
2 tablespoons chopped fresh parsley, optional
Choosing the Best Ingredients
Jumbo pasta shells are the main part of this recipe, so choose a box with intact shells whenever possible. A few shells may tear while boiling, so cook a few extra if you have them. This gives you enough good shells to fill the baking dish.
Ground beef with a little fat gives the filling more flavor. Lean ground beef also works well, but you may want to add a splash of sauce or broth if the filling seems dry. Ground Italian sausage can replace half of the beef for a bolder flavor.
Use a marinara sauce that you already enjoy. A good jarred marinara makes this recipe fast and reliable. You can use homemade sauce if you prefer, but it should not be too watery because the shells need a thick sauce to stay nicely layered in the baking dish.
Ricotta creates a soft, creamy filling. Cottage cheese can be used instead if that is what you have. Mozzarella gives the dish its stretchy melted topping, while Parmesan adds a salty, nutty flavor.
How to Make Cheesy Beef Stuffed Shells
Preheat your oven to 375°F. Lightly grease a 9-by-13-inch baking dish with olive oil or cooking spray.
Bring a large pot of salted water to a boil. Add the jumbo pasta shells and cook them for about two minutes less than the package directions. They should be flexible but still firm enough to hold their shape. Drain the shells carefully and place them on a baking sheet or clean towel so they do not stick together.
Heat olive oil in a large skillet over medium heat. Add the diced onion and cook for three to four minutes, until softened. Add the garlic and cook for about 30 seconds, stirring constantly.
Add the ground beef to the skillet. Break it apart with a wooden spoon and cook until browned. Ground beef should reach an internal temperature of 160°F. Drain excess grease if needed.
Stir in 1 cup of marinara sauce, Italian seasoning, garlic powder, onion powder, black pepper, salt, and red pepper flakes if using. Let the mixture simmer for three to five minutes, then remove it from the heat and allow it to cool slightly.
In a medium bowl, combine ricotta cheese, the egg, Parmesan cheese, 1/2 cup mozzarella cheese, and chopped parsley. Stir until smooth. Add the cooled ground beef mixture and stir until everything is evenly combined.
Spread 1 1/2 cups of marinara sauce over the bottom of the prepared baking dish. This layer keeps the shells moist and prevents them from sticking.
Use a spoon to fill each pasta shell with the beef and cheese mixture. Arrange the filled shells in the baking dish with the opening facing upward. Spoon the remaining marinara sauce over and around the shells.
Sprinkle the remaining mozzarella cheese evenly over the top. Cover the baking dish loosely with foil and bake for 20 minutes. Remove the foil and continue baking for another 5 to 10 minutes, until the cheese is melted, bubbly, and lightly golden.
Let the dish rest for five to ten minutes before serving. This helps the sauce thicken slightly and makes the shells easier to serve.
Tips for Perfect Stuffed Shells
Cook the shells only until al dente. Overcooked shells can tear easily and become too soft after baking. Slightly undercooked shells finish perfectly in the oven.
Let the beef filling cool for a few minutes before mixing it with ricotta and egg. Adding very hot beef directly to the cheese mixture can cause the egg to start cooking too early.
Use a spoon or small cookie scoop to fill the shells. This makes the process faster and keeps the filling neat. Do not overfill the shells because they can split while baking.
Keep enough sauce under and around the shells. The sauce prevents dry edges and gives the pasta a tender texture. If the dish looks dry before baking, add a little extra marinara or a small splash of water.
For an extra golden cheese topping, broil the casserole for one or two minutes at the end. Watch it closely, because the cheese can brown quickly.
Easy Variations
For a sausage version, use half ground beef and half Italian sausage. Mild or hot sausage both work well depending on your family’s taste.
For spinach stuffed shells, stir one cup of chopped cooked spinach into the ricotta mixture. Make sure excess moisture is squeezed out before adding it.
For a mushroom and beef version, sauté sliced mushrooms with the onions. Mushrooms add a deep savory flavor that pairs beautifully with tomato sauce and cheese.
For a vegetable version, add finely diced bell peppers, zucchini, or shredded carrots to the beef mixture. Cook the vegetables with the onions until softened before adding the ground beef.
For a spicy version, use hot Italian sausage, extra red pepper flakes, or spicy marinara sauce. You can also top the finished dish with pickled jalapeños or a drizzle of hot sauce.
What to Serve with Stuffed Shells
Garlic bread is a classic choice for cheesy stuffed shells. It is perfect for scooping up the extra marinara sauce from the plate.
A fresh green salad with lettuce, cucumbers, tomatoes, and Italian dressing helps balance the rich pasta and cheese. Caesar salad, roasted broccoli, green beans, or zucchini are also excellent side dishes.
For a larger dinner spread, serve the stuffed shells with antipasto vegetables, olives, roasted peppers, and a simple dessert such as cookies or fruit.
Make-Ahead Instructions
You can assemble the entire casserole up to one day before baking. Prepare the shells, fill them, arrange them in sauce, and cover the dish tightly with foil. Store it in the refrigerator until ready to bake.
When baking a cold casserole, add about 10 extra minutes to the covered baking time. Check that the sauce is bubbling and the shells are hot in the center before removing the foil.
You can also prepare the beef filling ahead of time and refrigerate it separately for up to two days. Cook and fill the shells when you are ready to assemble the dish.
Storing Leftovers
Store leftover Cheesy Beef Stuffed Shells in an airtight container in the refrigerator for up to three days. Keep the sauce with the shells to prevent them from drying out.
To reheat, place a few shells in a microwave-safe dish with a spoonful of marinara sauce. Cover loosely and heat until hot throughout.
For oven reheating, place the shells in a baking dish, add extra sauce if needed, cover with foil, and bake at 350°F for about 15 to 20 minutes.
Can You Freeze Stuffed Shells?
Yes. Stuffed shells freeze very well and are excellent for meal prep. Assemble the shells in a freezer-safe dish with the sauce, but do not bake them. Cover tightly with plastic wrap and foil, then freeze for up to two months.
To bake from frozen, remove the plastic wrap and cover with foil. Bake at 375°F for about 45 to 55 minutes, then uncover, add the cheese if needed, and bake until hot and bubbly.
For best results, thaw the casserole overnight in the refrigerator before baking. This reduces baking time and helps the shells heat more evenly.
Common Mistakes to Avoid
Do not overcook the pasta shells. Soft shells are much more likely to tear when filling them, and they can become mushy after baking.
Avoid using a filling that is too hot. Let the beef cool slightly before combining it with ricotta and egg.
Do not forget the sauce on the bottom of the pan. Without it, the shells can stick or dry out during baking.
Avoid overcrowding the baking dish. Arrange the shells in a single layer when possible. This helps them heat evenly and keeps the topping nicely melted over each shell.
Frequently Asked Questions
Can I use cottage cheese instead of ricotta?
Yes. Cottage cheese is a good substitute for ricotta. For a smoother texture, blend it briefly before mixing it with the beef and seasonings.
Can I use store-bought meat sauce?
Yes. Store-bought meat sauce can save time. If you use it, reduce the amount of plain marinara and adjust the amount of ground beef in the filling.
How many shells should I cook?
Cook about 24 to 28 shells, even if you only need 20 to 24 for the dish. A few can break while boiling, so having extras is helpful.
Can I make this without egg?
Yes. The egg helps bind the ricotta filling, but the dish will still work without it. The filling may be slightly softer, but it will remain delicious.
Can I use another cheese?
Absolutely. Provolone, Monterey Jack, cheddar, fontina, or an Italian cheese blend all work well in this recipe.
