Sausage and Ricotta Stuffed Shells
Ingredients
For the Shells and Filling
- 24-30 jumbo pasta shells
- 1 pound Italian sausage casings removed (sweet or hot, your preference)
- 1 tablespoon olive oil
- 1 medium onion finely diced
- 3 cloves garlic minced
- 2 cups fresh spinach roughly chopped (optional)
- 15 oz ricotta cheese
- 1 large egg
- 2 cups shredded mozzarella divided
- 1/2 cup grated Parmesan cheese divided
- 2 tablespoons fresh basil chopped (or 2 teaspoons dried)
- 1 tablespoon fresh parsley chopped
- 1/2 teaspoon dried oregano
- 1/4 teaspoon nutmeg optional
- Salt and freshly ground black pepper to taste
For the Sauce
- 3 cups marinara sauce homemade or good quality jarred
- 1/2 teaspoon red pepper flakes optional
Instructions
- Preheat your oven to 375°F (190°C).
- Cook the pasta shells according to package directions, but keep them slightly undercooked (very al dente). They'll finish cooking in the oven. Drain and rinse with cool water to stop the cooking process. Set aside on a baking sheet to prevent sticking.
- While the pasta cooks, prepare the filling. Heat olive oil in a large skillet over medium heat. Add the Italian sausage, breaking it into small crumbles as it cooks until browned and no longer pink, about 5-7 minutes.
- Add the diced onion to the skillet with the sausage. Cook until softened, about 3-4 minutes.
- Stir in the minced garlic and cook for another 30 seconds until fragrant. If using spinach, add it now and cook until wilted, about 1-2 minutes.
- Remove from heat and let the sausage mixture cool slightly while you prepare the cheese filling.
- In a large mixing bowl, combine the ricotta, egg, 1 cup of mozzarella, 1/4 cup of Parmesan, basil, parsley, oregano, and nutmeg (if using). Season with salt and pepper to taste.
- Add the cooled sausage mixture to the cheese mixture and stir until well combined.
- Prepare the baking dish by spreading 1 cup of marinara sauce evenly across the bottom.
- Fill each pasta shell with a generous spoonful of the sausage and ricotta mixture. Place the filled shells in the baking dish, open side up.
- Pour the remaining marinara sauce over the stuffed shells. Sprinkle with red pepper flakes if using.
- Top with the remaining mozzarella and Parmesan cheese.
- Cover the dish with aluminum foil and bake for 25 minutes. Then remove the foil and bake for an additional 5-10 minutes until the cheese is bubbly and golden.
- Let the dish rest for 5 minutes before serving. Garnish with additional fresh herbs if desired.
Notes
- Cook a few extra pasta shells as some may tear during boiling.
- For a lighter version, use turkey or chicken Italian sausage.
- The filling can be made a day ahead and refrigerated until you’re ready to stuff the shells.
- Completely assembled shells can be refrigerated (covered) for up to 24 hours before baking. Add 10-15 minutes to the covered baking time if coming straight from the refrigerator.
- This dish freezes beautifully. Freeze before baking, then thaw overnight in the refrigerator and bake as directed, adding about 15 minutes to the cooking time.

Common Mistakes to Avoid
- Overcooking the pasta shells. They should be very al dente as they’ll continue cooking in the oven. Overcooked shells will tear when you try to fill them.
- Not draining the spinach well enough. Excess moisture can make your filling watery. If using frozen spinach, be sure to squeeze out all excess moisture.
- Skipping the cooling step for the sausage. Adding hot sausage to the cheese mixture can cause the eggs to scramble and the cheese to break down.
- Overfilling the shells. This can make them difficult to arrange in the baking dish. Fill them about 3/4 full for best results.
- Not covering with foil for the initial baking period. This helps the filling heat through without the cheese on top burning.
Alternatives & Substitutions
- Meat options: Ground beef or turkey can replace the sausage. For a vegetarian version, use chopped mushrooms sautéed until their moisture evaporates.
- Cheese variations: Cottage cheese (drained) can substitute for ricotta. Add some provolone or fontina to the cheese mixture for added flavor.
- Greens alternatives: Kale, arugula, or thawed frozen spinach (well-drained) all work in place of fresh spinach.
- Sauce options: Use vodka sauce, arrabbiata for a spicier version, or a creamy Alfredo for a completely different take.
- Add more vegetables: Finely diced bell peppers, grated zucchini (moisture squeezed out), or chopped artichoke hearts make delicious additions.
- Gluten-free option: Use gluten-free jumbo shells and ensure your sausage is gluten-free.
FAQs
Can I make this dish ahead of time?
Absolutely! You can prepare the entire dish up to the point of baking, cover it tightly with plastic wrap and then foil, and refrigerate for up to 24 hours. When you’re ready to bake, remove the plastic wrap, keep the foil on, and add about 10-15 minutes to the initial covered baking time.
How do I prevent the shells from tearing?
Don’t overcook them – they should be very al dente. Also, handle them gently when filling. If some tear, don’t worry! Just place them in the baking dish with the tear side down.
What can I serve with stuffed shells?
A simple green salad with a light vinaigrette and garlic bread make perfect accompaniments. For a more substantial meal, add roasted vegetables on the side.
Can I freeze leftovers?
Yes! Leftovers can be frozen in airtight containers for up to 3 months. Thaw overnight in the refrigerator and reheat in a 350°F oven until heated through, about 20-25 minutes.
I don’t have jumbo shells. What else can I use?
Manicotti tubes work well with this filling, as do cannelloni. You could also use the filling to make a lasagna, layering it between the noodles with sauce and cheese.
