Seafood Baked Pasta
A restaurant-style seafood pasta bake starring shrimp and lump crab in a silky, creamy tomato sauce, finished with a cheesy golden crust. Rich and comforting yet bright from tomato and aromatics, it’s an elegant addition to a baked-pasta lineup and perfect for weeknight dinners or casual entertaining.
Jake Woods's note
"This bake balances decadent cream and cheese with delicate seafood — the crab keeps it special while shrimp adds satisfying texture. It shines for family dinners and small dinner parties when you want something impressive but easy to assemble."
About This Recipe
This seafood baked pasta brings restaurant polish to a weeknight table: sweet lump crab and tender shrimp folded through penne in a silky, creamy tomato sauce and finished under a bronzed blanket of mozzarella and Parmesan. The contrast is what sells it — the gentle brine and flake of crab, the snap of shrimp, and the toothsome penne held together by a sauce that’s rich without feeling heavy because bright tomato and sautéed aromatics keep it lively.
What makes this version reliable at home is the balance of technique and timing: crushed tomatoes give body without stomaching whole tomatoes, heavy cream tempers acidity and yields that glossy finish, and folding the seafood off the heat protects delicate texture. Splitting the cheese between the interior and the top creates a molten, stringy center and a golden, gratinéed crust, so every spoonful has both creaminess and crunch. It’s an excellent choice for family dinners where you want something a little special and for casual entertaining when you want easy make-ahead strategies and an impressive presentation.
Ingredients for Seafood Baked Pasta
- 12 oz Penne rigate (dried)
- 2 tbsp Olive oil
- 2 tbsp Unsalted butter
- 1 medium Yellow onion, finely chopped
- 3 cloves Garlic, minced
- 28 oz Crushed tomatoes
- 3/4 cup Heavy cream
- 12 oz Raw shrimp, peeled and deveined
- 8 oz Lump crab meat (fresh or canned)
- 2 cups Cheese blend (shredded mozzarella + grated Parmesan)
How to Make Seafood Baked Pasta
Step 1: Cook the pasta al dente
Bring a large pot of well-salted water to a rolling boil and cook the penne one minute shy of package directions so it’s slightly underdone. Reserve 1 cup of the starchy pasta water, then drain the pasta and set aside while you make the sauce.For this step
- 12 ozPenne rigate (dried)
Step 2: Sweat the aromatics
Heat the olive oil and butter in a large skillet over medium heat until the butter melts and foams. Add the chopped onion and cook until translucent, 5–7 minutes, then add the minced garlic and cook 30–45 seconds until fragrant, taking care not to brown.For this step
- 2 tbspOlive oil
- 2 tbspUnsalted butter
- 1 mediumYellow onion, finely chopped
- 3 clovesGarlic, minced
Step 3: Build the creamy tomato sauce
Pour in the crushed tomatoes, stir to combine, and bring to a gentle simmer; cook 8–10 minutes to thicken slightly. Stir in the heavy cream, season with salt and freshly ground black pepper to taste, and simmer 2–3 minutes more until the sauce is smooth and glossy.For this step
- 28 ozCrushed tomatoes
- 3/4 cupHeavy cream
Step 4: Combine pasta, seafood and cheese
Off the heat, fold the drained penne into the sauce along with half of the cheese blend, the lump crab meat, and the raw shrimp; toss gently so the crab stays in pieces and the shrimp is coated. Add a splash of the reserved pasta water if the sauce needs loosening, then transfer the mixture to a lightly oiled 9x13-inch baking dish and sprinkle the remaining cheese evenly over the top.For this step
- 12 ozRaw shrimp, peeled and deveined
- 8 ozLump crab meat (fresh or canned)
- 2 cupsCheese blend (shredded mozzarella + grated Parmesan)
Step 5: Bake until bubbly and golden
Bake in a preheated 400°F (200°C) oven for 12–15 minutes until the cheese is melted and edges are bubbling; broil 1–2 minutes if you want a deeper golden crust. Let the bake rest 5 minutes before serving so the sauce sets slightly and plating is tidy.

Seafood Baked Pasta Tips
Undercook the pasta
Boil the penne one minute less than package directions so it finishes cooking in the oven without turning mushy.
Reserve pasta water
Keep 1 cup of cooking water; a splash loosens the sauce and helps it cling to the pasta thanks to the starch.
Protect the seafood
Fold in crab and raw shrimp off the heat so the residual warmth coats but doesn't overcook them before baking.
Split the cheese
Stir half the cheese into the pasta for creaminess and scatter the rest on top for a golden, gratinéed finish.
Watch the broiler
If you broil to brown the top, keep the dish several inches from the element and check constantly to avoid burnt spots.
Seafood Baked Pasta Variations and Substitutions
White wine & lemon
Skip the tomatoes and add 1/2 cup dry white wine and 2 tbsp lemon juice to the cream for a lighter, bracing sauce that highlights seafood.
Gluten‑free option
Use your favorite gluten‑free penne and cook it exactly like the recipe; a corn‑rice blend works best to retain al dente texture.
Scallop and mussel mix
Swap half the shrimp for seared scallops and toss in a handful of cooked mussels for a more varied shellfish bake.
Dairy‑free swap
Replace heavy cream with canned full‑fat coconut milk and the cheeses with a sprinkle of nutritional yeast and a dairy‑free shredded blend, though keep flavors simple to let the seafood shine.
How to Store and Make Seafood Baked Pasta Ahead
Store leftovers in an airtight container in the refrigerator for up to 48 hours; seafood degrades faster than other baked pastas. Reheat gently in a 350°F oven for 12–15 minutes covered with foil, or microwave in short bursts, taking care not to overcook the shrimp. To make ahead, assemble through the sauce-and-pasta stage without the seafood, refrigerate up to 24 hours, then fold in crab and shrimp and bake just before serving.
What to Serve With Seafood Baked Pasta
Serve with a crisp, peppery mixed‑green salad dressed with lemon vinaigrette and a loaf of rustic bread to soak up the sauce. Bright garnishes—lemon wedges, chopped parsley, and a drizzle of good olive oil—cut the richness, while a chilled Vermentino or unoaked Chardonnay pairs beautifully with the briny seafood.
Seafood Baked Pasta FAQs
Can I use frozen shrimp or crab?
Yes—thaw completely in the refrigerator, pat dry to remove excess moisture, and drain any canned crab well; soggy seafood dilutes the sauce and prevents a good crust.
How do I prevent rubbery shrimp?
Undercook pasta intentionally and fold raw shrimp into the warm sauce off the heat so they only finish cooking in the oven; large shrimp can be halved so they heat evenly.
Is it safe to assemble this ahead with seafood inside?
It's safer to assemble without the seafood if you plan to refrigerate more than a few hours; add crab and shrimp just before baking to preserve texture and food safety.
Can I freeze the baked pasta?
I don't recommend freezing after baking—seafood becomes watery and rubbery. You can freeze the pasta and sauce (no seafood) for up to 2 months, then thaw, stir in fresh seafood, and bake.
My sauce is too thin—how do I thicken it?
Simmer longer to reduce it, or stir in a few tablespoons of grated Parmesan which melts and thickens; a small splash of the reserved starchy pasta water will also help bind the sauce.
