Creamy Seafood Stuffed Shells

The kitchen still smells like butter and shellfish the morning after I first made these stuffed shells for my sister's birthday dinner. She'd been hinting at something special for weeks, and I wanted to surprise her with a dish that felt fancy without requiring a culinary degree.

I may have gone overboard buying twice the seafood I needed, convinced the filling needed more. Turns out the recipe proportions are perfect, though having extra crabmeat around for impromptu snacks was hardly a tragedy.

Ingredients

• 16 jumbo pasta shells: Buy an extra box because shells always tear or stick together
• 225 g cooked shrimp: Fresh shrimp you cook yourself tastes noticeably better than pre cooked
• 120 g lump crab meat: Pick through carefully for shell fragments
• 225 g ricotta cheese: Whole milk ricotta makes a noticeably creamier filling
• 110 g cream cheese: Let it soften completely at room temperature first
• 60 g grated Parmesan cheese: Use freshly grated for the best melt
• 1 egg: Room temperature eggs incorporate more smoothly
• 2 tbsp fresh parsley: Flat leaf parsley has a cleaner flavor than curly
• 2 tbsp chives or green onions: Chives give a milder onion flavor
• 1 clove garlic: Freshly minced garlic beats garlic powder here
• ½ tsp salt: Adjust based on whether your seafood was preseasoned
• ¼ tsp black pepper: Freshly cracked pepper makes a difference
• ¼ tsp crushed red pepper flakes: Add if you want gentle warmth
• 2 tbsp unsalted butter: Unsalted lets you control the seasoning
• 2 tbsp all-purpose flour: This creates the roux base for the sauce
• 350 ml whole milk: Whole milk creates the richest sauce
• 120 ml heavy cream: This makes the sauce luxurious
• 60 g grated Parmesan cheese: For sauce depth and umami
• 1 tsp lemon zest: Brightens the rich seafood flavors
• 2 tbsp fresh lemon juice: Acid cuts through the creaminess
• ¼ tsp ground nutmeg: Just enough to enhance without dominating
• 50 g shredded mozzarella cheese: Creates that beautiful golden top
• 2 tbsp grated Parmesan cheese: Extra for the finishing layer

Instructions

Get your oven and dish ready:

Preheat oven to 180°C and lightly grease a 22 x 33 cm baking dish with butter.

Cook the pasta shells:

Boil shells in salted water until al dente, then drain and rinse under cold water immediately.

Mix the seafood filling:

Combine shrimp, crab, ricotta, cream cheese, Parmesan, egg, herbs, garlic, and seasonings in a large bowl.

Start the béchamel sauce:

Melt butter over medium heat, whisk in flour for 1 minute, then gradually whisk in milk and cream.

Finish the sauce:

Simmer until thickened, then stir in Parmesan, lemon zest, lemon juice, nutmeg, salt, and pepper.

Layer the foundation:

Spread one third of the sauce across the bottom of your prepared baking dish.

Stuff the shells:

Fill each shell with about 2 tablespoons of the seafood mixture and place open side up in the dish.

Add sauce and cheese:

Pour remaining sauce over shells and sprinkle with mozzarella and extra Parmesan.

Bake until bubbly:

Cover with foil and bake 25 minutes, then uncover and bake 10 more minutes until golden.

Let them rest:

Wait 5 minutes before serving so the filling sets slightly.

Save to Pinterest

My sister took one bite and immediately asked when I was making them again. That's when I knew this recipe had graduated from special occasion to regular rotation.

Make Ahead Magic

You can assemble the entire dish up to 24 hours before baking and refrigerate covered. Just add 5 to 10 minutes to the covered baking time if cooking from cold.

Seafood Substitutions

Lobster or scallops work beautifully here, though they will change the price point dramatically. The cooking time stays the same regardless of your seafood choices.

Serving Suggestions

A crisp green salad with vinaigrette cuts through the richness, and garlic bread is never a mistake. Keep sides simple so the shells remain the star.

• Pinot Grigio or Sauvignon Blanc pair perfectly
• Extra lemon wedges on the side let guests adjust brightness
• Fresh herbs make the final dish look professionally plated
