Shells, Filling, and Assembly Ingredients

• ½ pound jumbo pasta shells
• 2 tablespoons olive oil
• 1 small yellow onion, chopped fine
• Salt and pepper, to taste
• 3 garlic cloves, minced
• 1 pound ground beef
• 2 tablespoons Italian seasoning
• 1 cup spaghetti sauce (for the filling)
• 2 cups ricotta cheese
• 1 cup shredded mozzarella cheese, divided
• ½ cup grated Parmesan cheese
• 1 large egg, beaten
• 1 cup spaghetti sauce (for the baking dish)
• Extra mozzarella and Parmesan for topping

Assemble, Fill, and Bake

1. Preheat oven to 350°F (175°C).
2. Bring a large pot of salted water to a boil.
3. Cook jumbo pasta shells until al dente according to package instructions.
4. Drain shells and rinse briefly with cold water to stop cooking.
5. Lay shells out on a baking sheet so they don’t stick while they dry.
6. Heat 2 tablespoons olive oil in a skillet over medium heat.
7. Add 1 small chopped yellow onion, season with salt and pepper, and cook 4–5 minutes until soft and fragrant.
8. Add 3 minced garlic cloves and cook 1–2 minutes.
9. Add 1 pound ground beef, break it up, and cook until browned, about 5–7 minutes.
10. Drain excess fat from the beef.

11. Stir in 2 tablespoons Italian seasoning and 1 cup spaghetti sauce; let the beef mixture cool slightly.

12. Beat 1 large egg.
13. In a large bowl, combine 2 cups ricotta, half the shredded mozzarella, ½ cup grated Parmesan, and the beaten egg.
14. Gently fold the cooled beef mixture into the cheese mixture until evenly combined.
15. Lightly grease a 9×13-inch baking dish.
16. Spread 1 cup spaghetti sauce across the bottom of the baking dish.
17. Fill each pasta shell with the beef-cheese mixture and arrange them open-side up in a single layer in the baking dish.
18. Sprinkle the remaining mozzarella and extra Parmesan over the filled shells.
19. Cover the dish with foil and bake 25–30 minutes.
20. Remove the foil for the last 5–10 minutes to brown and bubble the cheese, then let the baked shells rest for a few minutes before serving.

Cooking and Assembly Tips

• Be sure not to overcook your pasta shells. You want them al dente so they keep their shape when baked.
• Let the beef mixture cool slightly before mixing it with the cheese. This keeps the cheese from melting too soon and helps everything blend better.
• Drain off excess fat from the beef to avoid greasy filling—nobody wants that!
• Fill each shell carefully but firmly to make sure they hold up nicely during baking—see the step-by-step in our Beef Stuffed Shells recipe.
• Cover the dish with foil while it bakes to keep moisture in, then remove it near the end to brown the top beautifully. This cover-then-uncover approach also suits eggplant rollatini with creamy filling.
• If your top cheese starts browning too fast, just tent it loosely with foil for the rest of the cook time.

Flavor Variations and Substitutions

• Vegetarian: Swap out the ground beef for sautéed mushrooms, zucchini, spinach, or a plant-based meat substitute for a veggie-friendly version; for mushroom-forward flavor inspiration, see this oyster mushroom pasta.
• Lean proteins: Use ground turkey or chicken to lighten things up without losing flavor—this healthy ground turkey zucchini casserole shows how to keep lean meat moist and tasty.
• Turn up the heat: Add crushed red pepper flakes or a pinch of cayenne to the beef mixture for a spicy kick.
• Seafood twist: Swap cooked shrimp or crab for ground beef and adjust the Italian seasoning to your taste.
• Cheese options: Mix things up with fontina, provolone, or gouda for different melty, gooey textures and flavors.
• Gluten-free: Use gluten-free jumbo shells and double-check that your sauces don’t contain gluten.

Storage, Make-Ahead, and Reheating

• Refrigerate leftovers: Place any extras in an airtight container and keep them in the fridge for up to 3 days. Reheat covered in a 350°F oven for 15–20 minutes until warmed through.
• Make ahead: You can fully assemble this dish and cover it tightly in the fridge for up to 24 hours before baking. Just add a few minutes to the baking time if it’s cold from the fridge. For an easy make-ahead side that holds well, pair the shells with this Kale Caesar Pasta Salad.
• Freeze for later: Assemble your unbaked shells in a freezer-safe container, cover tightly, and freeze for up to 3 months. When you’re ready, thaw overnight in the fridge and bake as usual—just expect a few extra minutes in the oven.
• Microwave reheating: For small portions, reheat gently in the microwave at medium power in 30- to 60-second bursts to avoid rubbery cheese.

Common Questions Answered

• Can I freeze already baked shells? Absolutely! Just wrap them tightly and freeze for up to 3 months. Reheat covered in a 350°F oven until piping hot. Keep in mind, reheating from frozen will take a bit longer.
• Is the egg necessary in the filling? The egg helps hold everything together and gives the filling a nice texture. If you want to skip it, use a bit more Parmesan or add a tablespoon of breadcrumbs to help bind the filling.
• How many shells should I plan per person? It varies depending on your group, but this recipe usually serves 6 to 8 people comfortably.
• Can this recipe be made dairy-free? Yes! Use dairy-free ricotta alternatives and vegan shredded cheeses, making sure your sauces are dairy-free too. The flavor will be different but still tasty.
• My shells are falling apart—what’s going wrong? Most likely, the pasta is overcooked. Make sure to cook shells just al dente, rinse with cold water afterward, and handle them gently when stuffing. If you’d like a similar, low-fuss stuffed dinner without pasta, try these Ground Beef Zucchini Boats.
