My classic Stuffed Shells are filled with a cheesy mixture of ricotta, parmesan, and melty mozzarella cheese nestled into a boat of marinara sauce. It's comfort food that fills a whole table of hungry friends and family. Stuffed Pasta Shells always disappear fast and reheat well, so you can enjoy it throughout the week.
Cook Pasta: Preheat oven to 375˚F. Cook shells in salted water according to package instructions (stirring several times to keep the pasta from sticking to the pot), then drain and fill pot with cold water to stop the cooking process and keep shells from sticking to each other.
Make the red sauce: In a deep pan over medium-high heat, add 1 Tbsp olive oil and sauté chopped onion until softened and golden (3-5 min). Add minced garlic, 1/2 tsp salt, 1/4 tsp pepper, and 1/4 tsp oregano. Sauté another 1 minute, stirring constantly until garlic is fragrant. Add 3 cups of marinara and bring to a uniform boil, then simmer for 2 minutes, and pour the sauce into the bottom of a 9x13 casserole dish.
Combine cheese filling: In a large bowl, add 15 oz ricotta cheese, 2 cups mozzarella, 1/3 cup parmesan, 1 egg, 1/4 cup parsley, 1/2 tsp salt, and 1/4 tsp black pepper. Stir until well combined.
Stuff the shells: Use about 1/2 ice cream scoop or just until filled (do not overstuff). Place them in the casserole over the marinara sauce in a single layer. Sprinkle the remaining 1 cup of mozzarella cheese over the top.
Bake: Cover with foil and bake for 30 minutes. The sauce should be bubbling at the edges. Remove foil and broil for 2-4 minutes to lightly brown the cheese. Remove from the oven and garnish with parsley to serve.
Notes
*Swap ricotta with drained cottage cheese, if necessary.Storage and Make Ahead
To Refrigerate: Assemble, cover with foil, and refrigerate unbaked stuffed shells within 2 hours for 1-2 days, then bake as directed, adding 5 minutes to the bake time if baking a chilled casserole. You can also refrigerate a fully cooked and cooled casserole.
Freezing: Fully assemble shells in a casseroledish (without baking), cover tightly with foil, and freeze up to 3 months. Bake from frozen (covered with foil) at 375˚F for about 45-55 minutes.
Reheating: Warm portions in the microwave or oven until shells are heated through to 165°F and cheese is melted.
*Reheating tip: Pasta tends to get dry when reheated, but here's a simple trick that could be used to retain moisture: Add a drizzle of water (marinara or broth) over your food before reheating. Also, to prevent splatter, we highly recommend using a plate cover.
