Simple, Classic Ingredients

• 20 jumbo pasta shells, cooked according to package instructions
• ½ medium onion, chopped
• 3 garlic cloves, minced
• 1 tsp salt, divided
• ½ tsp freshly ground black pepper, divided
• ¼ tsp dried oregano
• 3 cups marinara sauce
• 15 oz ricotta cheese*
• 1 large egg
• ⅓ cup parmesan cheese
• 3 cups shredded mozzarella cheese, divided
• ¼ cup fresh parsley, plus more for garnish

Step-by-Step Method

1. Preheat oven to 375°F.
2. Boil jumbo pasta shells in generously salted water according to package instructions until al dente, stirring occasionally; drain and transfer shells to cold water to stop cooking and prevent sticking.
3. Heat 1 tablespoon olive oil in a large pan over medium-high heat and sauté 1/2 chopped onion until soft and golden, about 3–5 minutes.
4. Add 3 minced garlic cloves, 1/2 teaspoon salt, 1/4 teaspoon freshly ground black pepper, and 1/4 teaspoon dried oregano to the pan and cook about 1 minute until fragrant.
5. Stir in 3 cups marinara sauce, bring to a boil, simmer 2 minutes, then pour the sauce into a casserole dish.
6. In a large bowl, mix 15 oz ricotta, 2 cups shredded mozzarella, 1/3 cup Parmesan, 1 large egg, 1/4 cup chopped parsley, 1/2 teaspoon salt, and 1/4 teaspoon pepper until smooth and creamy.

7. Spoon the cheese mixture into each shell about halfway and arrange the stuffed shells in a single layer over the marinara in the casserole dish.

8. Sprinkle the remaining 1 cup shredded mozzarella evenly over the stuffed shells.
9. Cover the dish with foil and bake at 375°F for 30 minutes until the sauce is bubbling at the edges.
10. Remove the foil and broil 2–4 minutes until the cheese is lightly browned, or if using a glass dish, increase the oven to 475°F and bake uncovered an additional 3–5 minutes until bubbly and golden.

Pro Tips for Best Results

For quick portioning, fill a scoop about halfway with the ricotta mixture before stuffing each shell.

Stuffed shells make a lovely vegetarian main dish. For a flavor-forward twist, try Sun-Dried Tomato and Ricotta Stuffed Shells. Top them with fresh parsley and serve with a bright green salad or your favorite veggies on the side.

This is a crowd-pleaser that feeds many and keeps meal prep light and easy. Prep is minimal, then the oven handles the rest. Serve with garlic bread for an extra cozy Italian-inspired dinner everyone will love, and balance the richness with a crisp Peach and Goat Cheese Salad.

Tasty Swaps and Add-Ins

If you want to shake things up a bit, try one of these tasty twists or diet-friendly swaps with no extra fuss:

• Meaty: Brown 1 pound of Italian sausage or ground beef, drain, and stir into either the marinara sauce or cheese filling before stuffing; for a heartier bake, try this stuffed pasta shells with ground beef variation.
• Spinach & Ricotta: Fold 8 ounces of cooked, well-drained spinach into the ricotta cheese for a fresh Florentine-style stuffing.
• Mushroom & Herbs: Sauté sliced mushrooms with a little garlic and thyme, then add them to your cheese filling for a rich, earthy flavor.
• White Version: Swap the marinara for a creamy béchamel or Alfredo sauce, skip broiling if you’re using glass, and top with extra mozzarella and Parmesan.
• Pesto: Stir in ⅓ to ½ cup basil pesto into the ricotta mixture or drizzle some pesto on top once baked for fresh herbal goodness.
• Cheese swaps: Use drained cottage cheese instead of ricotta, or add mascarpone, provolone, or fontina for different textures and extra richness.
• Gluten-free or alternative pasta: Use gluten-free jumbo shells, manicotti tubes, or roll cooked lasagna noodles if jumbo shells aren’t available.
• Individual portions: Assemble stuffed shells in single-serving ramekins or muffin tins for easy freezer-friendly meals.

Make-Ahead and Storage Guide

Here’s how you can store, freeze, and make this meal ahead for super-simple weeknight dinners or lunchboxes; for more packable ideas, browse 15 easy pasta salad recipes you can make in 30 minutes:

• Refrigerate assembled (unbaked): Cover well with foil and refrigerate within 2 hours of assembling for up to 1-2 days. When baking from chilled, add about 5 minutes to the baking time.
• Refrigerate cooked leftovers: Store any cooled, baked stuffed shells in an airtight container for 3-4 days.
• Freeze unbaked: Put together your unbaked shells in a casserole dish, cover tightly with foil and plastic wrap, and freeze for up to 3 months. Bake from frozen (covered) at 375°F for 45-55 minutes until bubbly, then finish as usual. The same method works for our beef stuffed shells recipe.
• Freeze baked: Once fully cooled, wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and reheat in a 350°F oven until warmed through to 165°F.
• Reheating tips: Warm leftovers in the microwave or oven until hot throughout. To keep shells from drying out, add a small drizzle of marinara or water over them and cover while reheating. If using glass bakeware, skip broiling and instead crank up the oven to about 475°F briefly to get the top melty and golden.

Answers to Common Questions

Here are answers to some of the most common questions about making stuffed shells at home:

• Can I assemble the shells ahead of time? Absolutely! You can stuff and refrigerate them unbaked for up to 2 days, or freeze unbaked for up to 3 months.
• Do the shells need to be cooked before stuffing? Yes, cook them al dente so they hold their shape during baking. Overcooking will make them too soft and fall apart.
• How do I keep the filling from getting watery? Use thick ricotta or drain your cottage cheese well. If adding spinach, squeeze out extra moisture first. Also, reduce very watery sauces a bit before assembling. You’ll find these same moisture-control tips in eggplant rollatini with creamy filling.
• Can I skip the egg in the filling? The egg helps the filling stick together, but you can leave it out and add ¼ cup breadcrumbs or some extra grated Parmesan instead.
• Can I use a glass dish if I want a browned top? Yes, just avoid broiling in glass. After baking covered, remove foil and raise oven temperature to around 475°F for a few minutes to brown the cheese instead.
• How long should I reheat leftovers? Reheat in a 350°F oven for 15-25 minutes, depending on the portion size, until hot inside (165°F). Microwaving works well too.
• Is there a gluten-free option? Yes! Gluten-free jumbo shells or other gluten-free pasta shapes work great—just follow package cooking directions. For a pasta-free, naturally gluten-free alternative, try Lasagna Zucchini Boats.
