Ingredients for Creamy Seafood Stuffed Shells

For the Homemade Sauce (or use 1 cup of your favorite jarred sauce)

• 1 1/2 tablespoons butter (divided: 1 tbsp + 1/2 tbsp)
• 1 tablespoon all-purpose flour
• 1/2 cup heavy whipping cream
• 1/2 cup unsweetened almond milk (or any milk you like)
• 1/4 cup dry white wine (I use Pinot Grigio—substitute broth if you prefer)
• 3 garlic cloves, minced
• 1/2 cup grated Parmesan Reggiano cheese
• 1/2 teaspoon Italian seasoning (start with 1/4 tsp and adjust to taste)
• Salt and pepper to taste

For the Shells and Filling

• 20 jumbo pasta shells (a 12 oz box has more than enough)
• 8 oz raw shrimp, peeled, deveined, chopped
• 8 oz lobster meat (thawed if frozen)
• 8 oz cream cheese
• 8 oz lump crab meat
• 2 cups finely chopped fresh spinach (or use thawed and drained frozen)
• 1 cup shredded mozzarella cheese (divided)
• 1/4 cup grated Parmesan Reggiano cheese
• 1 1/2 teaspoons Old Bay seasoning (or your favorite seafood seasoning)
• Salt and pepper to taste

Step-by-Step Instructions for Creamy Seafood Stuffed Shells

1. Prep Your Pasta Shells

Boil the shells just shy of al dente (about 2 minutes less than the package suggests). This keeps them firm and easy to stuff. Trust me—this step matters. Softer shells = tears and mess.

2. Make the Cream Sauce

• Melt 1 tablespoon butter in a skillet.
• Whisk in flour until it forms a smooth paste.
• Slowly whisk in cream, almond milk, and wine.
• Stir in garlic, Parmesan, and Italian seasoning.
• Keep whisking until creamy and smooth. Taste and adjust!

I always sneak an extra sprinkle of Parmesan here—there’s no such thing as too cheesy in my house.

3. Cook the Seafood

• Heat remaining 1/2 tablespoon butter in the skillet.
• Add shrimp and lobster, cooking just until opaque (about 2–3 minutes per side).

Don’t overcook—the seafood finishes baking in the oven.

4. Mix Up the Filling

• In a large bowl, combine: shrimp, lobster, crab, cream cheese, spinach, 1/2 cup mozzarella, Parmesan, Old Bay, salt, and pepper.
• Mix well and taste. Adjust the seasoning—you want it bold and savory.

This is where I sometimes sneak in a pinch of chili flakes or fresh lemon zest for a twist.

5. Stuff and Bake

• Preheat oven to 375°F.
• Spoon about 1.5 to 2 tablespoons of filling into each shell.
• Spread your sauce in the bottom of a 9×13-inch baking dish.
• Place shells on top of the sauce.
• Sprinkle remaining mozzarella over the shells.
• Cover with foil and bake for 20 minutes.
• Uncover and bake 5–10 more minutes, until cheese is bubbly and golden.

Pro Tips for Perfect Seafood Shells

• Make ahead: Stuff the shells and store them in the fridge a day in advance.
• Freeze-friendly: Freeze prepped shells in a foil tray. Bake from frozen with extra time.
• Use leftovers: Got leftover salmon or scallops? Toss them in the filling.
• Sauce swaps: Try these with seafood stuffed shells with red sauce if you’re a marinara fan.
