Seafood Pasta Recipe White Sauce: Garlic-Infused Creamy Luxe With Shrimp and Scallops

This seafood pasta delivers a creamy white sauce that perfectly complements tender shrimp and scallops.

I developed this method to ensure the sauce coats every noodle while letting the seafood shine. The garlic-infused base adds depth without overpowering the delicate flavors.

The seafood quality is paramount. Wild-caught shrimp and dry-packed scallops (available at Whole Foods or Trader Joe’s) yield the best texture. Avoid pre-frozen seafood if possible—freshness shines in this dish. The Parmesan should be a Parmigiano-Reggiano wedge; pre-grated varieties lack the necessary melt and depth. For the wine, any crisp dry white works, but avoid cooking wines with added salt.

No white wine? Seafood stock plus a splash of lemon juice creates a similar acidity. Shrimp can be swapped for langoustines or prawns if available. Scallop alternatives include halibut or cod chunks—just adjust cooking time accordingly. For a lighter version, substitute half-and-half for heavy cream, though the sauce will be less luxurious. Always pat seafood completely dry to ensure proper searing.

This dish is best served immediately, but leftovers keep for 2 days refrigerated. Reheat gently to avoid curdling the sauce. The cooked pasta can be stored separately and tossed with fresh sauce when reheating. Never freeze seafood pasta—the texture deteriorates significantly.

Step-by-Step Instructions for Seafood Pasta in White Sauce

This method ensures a restaurant-quality dish with perfectly cooked seafood and a velvety sauce.

Step 1: Cook the Linguine Pasta Al Dente

Bring a large pot of salted water to a rolling boil. Add the 12 oz Linguine Pasta and cook according to package instructions until al dente—about 1 minute less than the suggested time. The pasta should have a slight bite to it, as it will finish cooking in the sauce.

Reserve 1 cup of pasta water before draining. This starchy liquid is essential for adjusting the sauce consistency later. Drain the pasta but do not rinse it—you want to preserve that surface starch for better sauce adhesion.

Step 2: Sauté Aromatics and Deglaze with Wine

In a large, deep skillet, melt ¼ cup of the 0.5 cup Unsalted Butter over medium heat. Add the finely diced 1 whole Shallot and cook for 2-3 minutes until translucent. Stir in the minced 6 cloves Garlic Cloves and 0.25 tsp Red Pepper Flakes, cooking for 30 seconds until fragrant.

Pour in the 0.5 cup Dry White Wine and simmer for 3-4 minutes until the liquid reduces by half. This step builds a flavorful foundation while allowing the alcohol to cook off. The mixture should smell aromatic and look slightly syrupy.

Step 3: Prepare the Seafood

Pat the 0.5 lb Bay Scallops completely dry with paper towels. In a separate large skillet, heat the 1 tbsp Olive Oil over medium-high heat. Add the scallops in a single layer and sear undisturbed for 1-2 minutes per side until golden brown and just cooked through. Transfer the scallops to a plate.

In the same skillet, add the remaining ¼ cup Unsalted Butter. Once melted, add the 1 lb Large Shrimp, seasoned with ½ tsp of the 1 tsp Kosher Salt and the 0.5 tsp Freshly Ground Black Pepper. Cook for 2-3 minutes per side until the shrimp turn opaque and pink. Remove from heat and set aside with the scallops.

Step 4: Create the Creamy Sauce and Combine

Reduce the heat under the skillet with the shallot-garlic mixture to low. Pour in the 1.5 cups Heavy Cream and simmer gently for 3-4 minutes, stirring occasionally. Avoid boiling, as this can cause the cream to separate.

Gradually whisk in the 0.75 cup Parmesan Cheese until fully melted and the sauce is smooth. Stir in the 1 tbsp Lemon Juice. Add the cooked linguine to the sauce, tossing to coat evenly. If the sauce is too thick, add reserved pasta water 1 tablespoon at a time until it reaches a silky consistency.

Step 5: Incorporate Seafood and Finish

Gently fold the cooked shrimp and scallops into the pasta and sauce, being careful not to break up the seafood. Warm everything through for 1-2 minutes on low heat. The sauce should cling beautifully to the pasta, with the seafood glistening and tender.

Taste and adjust seasoning with the remaining ½ tsp Kosher Salt if needed. Garnish with the chopped 0.25 cup Fresh Parsley just before serving. Each plate should showcase the creamy sauce coating every strand of pasta, with the shrimp and scallops distributed evenly throughout.

Flavor Customization for This Dish

🔥 Make it Spicier

For a bold kick, stir in 2 tsp of cayenne pepper or 1 tbsp of crushed red pepper flakes into the white sauce while simmering. This adds a fiery depth that pairs beautifully with the sweetness of shrimp and scallops. Balance the heat with a splash of cream if needed.

Add Sweetness 🍯

Enhance the natural sweetness of the seafood by adding 1 tbsp of honey or 2 tsp of maple syrup to the sauce. This subtle sweetness complements the briny flavors and rounds out the dish’s richness.

Tangy Twist 🍋

A splash of acidity brightens the creamy sauce. Try 1 tbsp of lemon juice or 1 tsp of white wine vinegar stirred in just before serving. The tang cuts through the richness and lifts the seafood flavors.

Extra Smoky 👨‍🍳

For a smoky depth, sprinkle in 1 tsp of smoked paprika or a dash of liquid smoke while sautéing the garlic. This adds a warm, earthy layer that pairs wonderfully with charred or grilled seafood.

Umami Boost ✨

Umami lovers can deepen the flavor with 1 tsp of fish sauce or 1 tbsp of grated Parmesan. These ingredients amplify the savory notes, making every bite of your seafood pasta more complex and satisfying.
