Cheesy Italian Stuffed Shells with Ground Beef Filling

If you love cozy, comforting pasta bakes that feel like a hug in a dish, this Cheesy Italian Stuffed Shells with Ground Beef Filling is exactly what your weeknight dinner routine has been missing. Think jumbo pasta shells, a seasoned ground beef and vegetable filling, creamy ricotta, melty mozzarella, and plenty of bright basil to finish. It’s simple enough for a busy weeknight but special enough to feed a crowd or bring to a potluck.

Why this Cheesy Italian Stuffed Shells with Ground Beef Filling works

This recipe balances texture and flavor: the tender shells hold a creamy, savory filling that’s studded with vegetables for texture and flavor. Ground beef adds heartiness and melts into the sauce so each bite is satisfying without being heavy. Two kinds of cheese—Parmesan folded into the ricotta and mozzarella melted on top—give you that classic Italian baked-pasta pull. Fresh basil at the end adds a fragrant lift so it never feels one-note.

Ingredients

Make sure you have everything prepped before you start—this keeps the process relaxed and streamlined.

• ▢10oz pastashells, large
• ▢½ tsp olive oil
• ▢1 tbsp olive oil
• ▢1 lbs ground beef
• ▢½ onion diced
• ▢½ red pepper diced
• ▢2 tsp garlic minced
• ▢¼ tsp salt
• ▢¼ tsp pepper
• ▢¼ tsp parsley dried
• ▢¼ tsp oregano dried
• ▢1 ½ cups ricotta cheese
• ▢2 tbsp Parmesan cheese grated
• ▢3 cups pasta sauce divided
• ▢½ cup mozzarella cheese
• ▢1 tbsp basil fresh leaves

Make-Ahead & Substitutions

If you want to prep ahead, you can cook the shells and make the filling a day in advance. Assemble the shells in a baking dish, cover tightly, and refrigerate; add the mozzarella and bake just before serving. For a lighter version, use part-skim ricotta and mozzarella. If you prefer a different protein, a ground turkey alternative works well using the same measurements and steps.

Tools you’ll need

• Large pot for boiling pasta
• Large skillet
• Mixing bowl
• Large spoon or spatula
• 9×13-inch baking dish (or similar)
• Spoon or small cookie scoop for stuffing shells

Step-by-step directions

1. Preheat and prepare: Preheat your oven to 350°F (175°C). Lightly oil a 9×13-inch baking dish with the ½ tsp olive oil to prevent sticking.
2. Cook the pasta shells: Bring a large pot of salted water to a boil. Add the 10oz of large pastashells and cook according to package directions until just al dente—still slightly firm since they will finish cooking in the oven. Drain and set aside on a sheet or bowl so they don’t stick together.
3. Cook the aromatics and vegetables: In a large skillet, warm 1 tbsp olive oil over medium heat. Add the diced ½ onion and diced ½ red pepper. Sauté until the onion is translucent and the pepper is softened, about 4–5 minutes.
4. Add the garlic: Stir in 2 tsp minced garlic and cook for 30–60 seconds, until fragrant. Be careful not to burn the garlic.
5. Brown the beef: Add 1 lbs ground beef to the skillet with the onion, pepper, and garlic. Break the meat up with a spoon and cook until it is no longer pink and begins to brown, about 6–8 minutes.
6. Season the meat: Sprinkle in ¼ tsp salt, ¼ tsp pepper, ¼ tsp dried parsley, and ¼ tsp dried oregano. Stir well to combine and allow the spices to bloom with the meat for 1–2 minutes. Remove the skillet from heat and let the mixture cool slightly.
7. Combine the cheese filling: In a mixing bowl, stir together 1 ½ cups ricotta cheese and 2 tbsp grated Parmesan cheese until smooth. Add about half of the cooled beef mixture into the ricotta and mix gently so the beef is evenly distributed through the cheese. If the beef mixture is very wet, drain any excess liquid first to prevent a watery filling.
8. Layer the sauce: Spread 1 cup of the 3 cups pasta sauce across the bottom of the oiled baking dish in an even layer. This creates a saucy base so the shells don’t stick and the bottom doesn’t dry out.
9. Stuff the shells: Using a spoon or small cookie scoop, fill each cooked pasta shell with a generous portion of the ricotta and beef mixture. Place each stuffed shell seam-side up in the prepared baking dish on top of the sauce. Arrange them in a single layer; they should fit comfortably without overcrowding. If you have extra filling, you can spoon it between shells.
10. Top with remaining sauce: Once all shells are stuffed and arranged, spoon the remaining 2 cups of pasta sauce evenly over the tops of the shells. The sauce should cover most of the exposed pasta so it steams and bakes tenderly.
11. Add cheese: Sprinkle ½ cup mozzarella cheese evenly over the top of the sauced shells. This will melt and create a bubbly, golden finish.
12. Bake: Bake the assembled dish in the preheated oven for 20–25 minutes, or until the sauce is bubbling and the mozzarella is melted and golden in spots. If you prefer a deeper browning on the cheese, broil for the final 1–2 minutes but watch carefully to avoid burning.
13. Finish and serve: Remove the baking dish from the oven and let it rest for 5 minutes. Scatter 1 tbsp fresh basil leaves over the top for a bright, fragrant finish. Serve hot, spooning extra sauce from the bottom of the dish over plates as desired.

Troubleshooting & tips

• Shells sticking together: After draining, spread shells on a lightly oiled sheet pan or toss gently with a touch of olive oil so they don’t clump.
• Too-wet filling: If the cooked beef releases a lot of liquid, drain it before adding to the ricotta. Excess moisture can make the filling runny and the final dish watery.
• Even stuffing: A small ice-cream scoop or tablespoon works great for even portions and faster assembly.
• Cheese melt: For creamier top cheese, cover the dish with foil for the first 15 minutes of baking, then remove foil for the last 5–10 minutes to brown the mozzarella.

Serving suggestions

These stuffed shells pair beautifully with a crisp green salad and a simple vinaigrette to cut through the richness. Garlic bread or a warm baguette is perfect for mopping up extra sauce. For a vegetable side, roast asparagus or a quick sauté of spinach with garlic complements the flavors nicely.

Storage and reheating

Refrigerate any leftovers in an airtight container for up to 3 days. To reheat, place in an oven-safe dish, cover with foil, and warm at 350°F (175°C) until heated through, about 15–20 minutes. You can also microwave single portions, covered, in 30-second intervals until hot.

Notes on flavor variations

• Spicy kick: Add ¼–½ tsp crushed red pepper to the beef mixture while cooking for a subtle heat.
• Herb swap: If you like a more herb-forward profile, stir a teaspoon of chopped fresh parsley or a pinch of thyme into the ricotta mixture.
• Vegetarian option: Replace the ground beef with a plant-based ground alternative following the same measurement and cooking method.
