Why This Recipe Works
- The ricotta filling is bound with an egg, keeping it creamy yet structured so it doesn’t ooze out while baking.
- Simmering the sausage directly in the marinara builds a deep, savory flavor without extra steps.
- Baking the shells covered first heats the filling evenly without drying it out, then a quick broil browns the cheese and makes it bubbly.
Ingredients & Why They Matter
- Italian Sausage: Adds richness and seasoning to the sauce. Pork sausage delivers the most flavor, but turkey or chicken sausage works for a lighter option.
- Yellow Onion: Adds sweetness and depth to the marinara. If needed, substitute 1 large shallot, finely diced.
- Garlic: Fresh garlic provides the best flavor; avoid jarred if possible. If needed, substitute 1–1½ teaspoons granulated garlic in place of the fresh cloves.
- Marinara Sauce: A high-quality jarred marinara keeps prep quick while still delivering bold flavor.
- Ricotta Cheese: Whole milk ricotta gives the creamiest filling. Cottage cheese is a great substitute if you don’t have ricotta on hand.
- Egg: Helps hold the ricotta filling together so it doesn’t spill out when baked.
- Basil Pesto: Adds another layer of flavor.
- Mozzarella Cheese: Mild and melts beautifully. If you’re in a pinch, provolone is a good substitute.
- Parmesan Cheese: Adds sharp, salty depth to the filling.
- Morton Kosher Salt: All of my recipes are tested with Morton kosher salt unless noted otherwise. It’s the best salt for everyday cooking because of its size and flavor. If using table salt, reduce the amount. I highly recommend picking up some kosher salt next time you’re at the store!
- Jumbo Pasta Shells: Be sure to buy jumbo pasta shells. These are large enough to be easily stuffed compared to regular-sized shells.

Baked Stuffed Shells Step by Step
- Boil the shells: Preheat the oven to 400°F (204°C). Bring a large pot of generously salted water to a boil. Add the jumbo pasta shells and cook until just al dente (1–2 minutes less than package directions; usually about 8 minutes). Drain the shells well and set aside to cool.
- While the shells are boiling, heat a large skillet or Dutch oven over medium-high heat. Add the Italian sausage and cook until mostly cooked through, breaking it apart with a wooden spoon.
- Make the sauce: Add the diced onion to the sausage and sauté 3–4 minutes until softened. Stir in the minced garlic and cook 30–60 seconds until fragrant. Pour in the marinara sauce and water, and reduce heat to low. Let the sauce simmer gently while you prepare the filling, stirring occasionally.
- Mix the filling: In a medium bowl, combine ricotta, egg, basil pesto, 1 cup of the shredded mozzarella, grated Parmesan, and kosher salt. Mix until smooth and evenly combined.
- Assemble the shells: Lightly grease a 9 x 13-inch (or 3.5-quart) oven-safe baking dish. Fill each cooled shell with about 2 heaping tablespoons of the ricotta mixture. Spoon the sausage marinara into the dish. Nestle them in the sauce with the slit side up.
- Bake and broil: Cover the baking dish tightly with foil. Bake for 25–30 minutes, until the filling is heated through. Remove the foil and sprinkle the remaining 1 cup of shredded mozzarella on top. Broil 1–2 minutes, watching closely, until the cheese is golden and bubbly. Let the dish rest a few minutes before serving.
Pro Tips for Perfect Baked Stuffed Shells
- Under-boil the shells: Slightly firm shells are easier to stuff and won’t fall apart. Remember, since they cook more in the oven, they have to be underboiled.
- Simmer the sauce: A gentle simmer thickens the marinara and deepens flavor.
- Use a small spoon: Preferably one that fits in the shell, which makes filling the shells faster and cleaner.
- Broil carefully: Cheese browns fast — keep a close eye on it.
Common Mistakes
- Skipping the egg: Without it, the filling can turn loose and watery, causing it to ooze out of the shells.
- Overcooking the pasta: This causes the shells to become mushy and fall apart.
- Adding cheese too early: Cheese steams under foil and turns gritty — always add it at the end.
Swap It Up: Variations to Try
- Vegetarian: Omit sausage and sauté 8 ounces mushrooms and 5 ounces fresh spinach instead.
- Spicy: Use hot Italian sausage and add a 1/4-1/2 teaspoon of red pepper flakes to the sauce.
- Make it lighter: Use chicken sausage and part-skim ricotta.
- Sun-Dried Tomato Pesto: Swap the basil pesto for sun-dried tomato pesto for a richer, slightly tangy flavor with a deeper savory note.
- Creamy Marinara: Instead of adding ¼ cup water to the sauce, stir in ¼ cup heavy cream for a richer sauce.
What To Serve With This Recipe
These baked stuffed shells pair perfectly with warm, crusty bread. Here are some great options:

Recipe FAQs
What temperature do you cook stuffed shells at in the oven?
Bake stuffed shells at 375°F. It’s the sweet spot for melty, creamy filling and bubbly sauce without drying anything out.
Should stuffed shells be covered when baking?
Covering keeps them moist and prevents the cheese from drying out.
Do you cook shells before stuffing them?
Boil just until al dente, then drain and let them cool slightly so they’re easy to handle and don’t tear.
