Ingredients

  • Lobster meat: select fresh or frozen tails for sweetness and firm texture
  • Lump crab meat: go for jumbo lump or freshly picked for clean flavor without shells
  • Garlic cloves: minced for brightness and bold flavor in the filling
  • All purpose flour: thickens the sauce for that creamy finish use unbleached if possible
  • Salt and pepper: essential to bring balance to the seafood and cheese
  • Shredded mozzarella cheese: divided to bring gooey texture inside and golden top finish look for whole milk mozzarella for better melt
  • Butter: unsalted preferred for control over seasoning adds richness and helps with sautéing
  • Cream cheese: softly whipped ensures a velvety base choose brick style for best texture
  • Heavy whipping cream: gives luscious body and extra silkiness to the sauce
  • Parmesan Reggiano cheese: grated for salty nutty dimension always grate from a block for sharpest flavor
  • Aluminum foil: covers the dish while baking to keep shells tender

Step-by-Step Instructions

Prepare the Seafood:
Start by melting half of the butter in a large skillet over medium heat. Sauté the minced garlic until it is just fragrant and releasing its aroma into the kitchen. Add lobster and crab carefully stir and cook for two to three minutes to warm through without overcooking. Transfer seafood off the heat so it stays moist
Make the Filling:
Combine your cooked seafood mixture with softened cream cheese in a big mixing bowl. Add half the shredded mozzarella and season with a pinch of salt and pepper. Stir until the filling is rich and unified with no streaks of cheese or cream
Cook the Jumbo Shells:
In a large pot of boiling water prepare your pasta shells al dente following the package directions. Drain them gently and let cool just enough to handle so shells remain intact during stuffing
Prepare the Sauce:
Use the same skillet you sautéed seafood in to keep all the flavor. Melt the remaining butter over medium. Sprinkle in flour and stir constantly for about a minute until just cooked. Pour in heavy cream slowly whisk well then add Parmesan and rest of the mozzarella. Stir continually until sauce has no lumps and glides off your spoon
Assemble the Dish:
Preheat your oven to three seventy five degrees. Spoon a thin layer of cheese sauce along the base of your baking dish to prevent sticking. Carefully stuff each pasta shell with seafood mixture nestling them snugly together in the dish. Pour the rest of your cheese sauce generously over the tops
Bake:
Cover the whole dish tightly with aluminum foil and bake twenty minutes. Remove foil and return to oven for another ten minutes or until sauce is bubbling and the tops are beautifully golden
Serve:
Let the pan cool a few minutes before scooping out the shells. Top with a sprinkle of grated Parmesan or some fresh herbs. Serve them steaming warm for the best experience

Parmesan Reggiano is my favorite ingredient here. It just ties the whole sauce together and adds a sharp depth that balances the richness. The first time my daughter tasted this at our holiday table she could not believe how restaurant quality it tasted but with that cozy family dinner feeling

Storage Tips

To store leftovers place them in an airtight glass or plastic container and keep refrigerated. They will stay fresh for up to three days. When you want to reheat just pop the shells into a baking dish cover with foil and warm at three fifty degrees for about fifteen minutes. These also microwave beautifully if you are just reheating one or two

Ingredient Substitutions

You can successfully swap crab for imitation crab if needed though the texture is slightly less delicate. Shrimp or scallops add new dimension if you need to stretch your seafood further or use what is local. Cornstarch works as a substitute for flour if making the dish gluten free and try swapping the cheeses for fontina or Gruyère for a fun twist

Serving Suggestions

Pair the rich shells with a crisp green salad using simple vinaigrette to balance the creamy flavors. Garlic bread is a classic side that soaks up the extra sauce perfectly. For veggies roasted asparagus or sautéed spinach round out the meal without overpowering the seafood
