Tools You’ll Need
Large pot (for boiling pasta)
Large skillet (for seafood mixture)

Baking dish
Spoon or piping bag (to fill shells)
Step-by-Step Instructions
Step 1: Cook the Jumbo Shells
Boil the pasta shells in a large pot of salted water, following package directions until al dente (usually 9-11 minutes).
Drain and set aside to cool. Once cooled, gently separate the shells to prevent sticking.
Step 2: Prepare the Seafood Filling
In a large skillet, heat olive oil over medium heat.
Add the garlic and sauté for 1-2 minutes until fragrant.
Add the chopped shrimp and scallops and cook for 3-4 minutes, until the seafood is just cooked through.
Remove from heat and let it cool slightly.
In a mixing bowl, combine the seafood with the ricotta, mascarpone, mozzarella, Parmesan, egg, parsley, lemon zest, salt, and pepper.
Mix thoroughly until the filling is smooth and well-combined.
Step 3: Prepare the Marinara Sauce
In the same skillet, add the marinara sauce along with oregano, basil, and red pepper flakes (if using).
Let the sauce simmer over low heat for 5-7 minutes to allow the flavors to meld together.
Taste and adjust seasoning if needed.
Step 4: Stuff the Shells
Preheat the oven to 375°F (190°C).
Spoon the seafood mixture into each cooked pasta shell, filling them generously.
Place the stuffed shells in a lightly greased baking dish.
Step 5: Assemble & Bake
Pour the marinara sauce evenly over the stuffed shells.
Top with a little extra mozzarella and Parmesan cheese for a cheesy finish.
Cover the baking dish with foil and bake for 25 minutes.
After 25 minutes, remove the foil and bake for an additional 5-10 minutes, until the cheese is golden and bubbly.
Step 6: Garnish & Serve
Once baked, remove from the oven and sprinkle with fresh parsley.
Serve hot, with extra marinara sauce on the side if desired.

Tips for Perfect Seafood Stuffed Shells
Cook Seafood Just Right – Avoid overcooking the shrimp and scallops; they should be tender and juicy.
Don’t Overstuff – While it’s tempting to add more filling, try not to overcrowd the shells for the best texture.
Use Fresh Ingredients – Fresh seafood and quality cheeses will make all the difference in flavor.
Let it Rest – Allow the shells to cool slightly before serving to set the cheese and filling.

Garlic bread – A perfect side to soak up the extra sauce.

Add a side of roasted potatoes or mashed potatoes for a heartier meal.
Pair with a glass of crisp white wine, such as Pinot Grigio or Sauvignon Blanc, for the ultimate dining experience.
