This dish brings coastal Italian flavors to your kitchen with tender shrimp and a bright lemon garlic white wine sauce. The technique matters as much as the ingredients here.

The shrimp quality is non-negotiable here. Wild-caught Gulf shrimp (16/20 count) give the best texture and flavor. Whole Foods or local seafood markets are ideal sources—avoid pre-frozen shrimp if possible. For the wine, a crisp Pinot Grigio from Trader Joe’s works perfectly (and you’ll have extra to enjoy with dinner). The Parmesan should be Parmigiano-Reggiano, freshly grated from a wedge.

No white wine? Substitute with extra chicken stock plus 1 tbsp lemon juice. Heavy cream can be swapped for half-and-half (slightly less rich) or coconut milk for a dairy-free version. Fresh parsley is ideal, but dried parsley at one-third the amount works in a pinch. If you’re out of shallots, yellow onion at double the quantity is a fine substitute.

The sauce keeps beautifully for 3 days in the fridge—store separately from pasta to prevent absorption. Freeze cooked shrimp in the sauce for up to 1 month. Always bring shrimp to room temperature before cooking (about 15 minutes on the counter).

Step-by-Step Instructions for Shrimp Portofino

Master this restaurant-quality dish with precise technique and perfect timing.

Step 1: Sear the Shrimp to Perfection

Heat the 2 tbsp extra-virgin olive oil in a large skillet over medium-high heat until it shimmers. Add the 1.5 lb large shrimp in a single layer, being careful not to overcrowd the pan. Season immediately with ½ tsp black pepper and ¼ tsp red pepper flakes.

Sear undisturbed for 2-3 minutes per side until the shrimp turn opaque pink with golden edges. The shrimp should curl into a loose “C” shape when done. Remove to a plate and tent with foil to keep warm—the residual heat will finish the cooking.

Step 2: Build the Aromatic Base

In the same skillet, reduce heat to medium and add ¼ cup unsalted butter. When melted, add the 1 whole shallot and 6 cloves garlic cloves. Sauté for 1-2 minutes until fragrant but not browned—the shallots should be translucent.

Pour in the 1 cup dry white wine and scrape up any browned bits from the shrimp. Simmer for 3-4 minutes until the liquid reduces by half. This deglazing step extracts maximum flavor from the pan and creates the foundation for your sauce.

Step 3: Create the Creamy Lemon Sauce

Add the ½ cup chicken stock and ¼ cup fresh lemon juice to the skillet. Simmer for 2 minutes until slightly reduced. Stir in the ½ cup heavy cream and remaining ¼ cup unsalted butter, whisking until the butter melts and the sauce emulsifies.

The sauce should coat the back of a spoon with a velvety texture. Taste and adjust seasoning with the 1 tsp salt if needed. The acidity from the lemon should balance the richness of the cream and butter.

Step 4: Combine with Pasta and Finish

Add the 12 oz linguine pasta (cooked al dente according to package instructions) to the skillet with the sauce. Toss gently to coat every strand. Return the shrimp to the pan along with any accumulated juices.

Sprinkle with the ½ cup parmesan cheese and toss for 1 minute until the cheese melts and everything is well combined. The pasta should glisten with sauce, not appear dry or soupy.

Step 5: Garnish and Serve Immediately

Transfer to serving plates and garnish with the ¼ cup fresh parsley. The parsley adds a pop of color and freshness that cuts through the richness. Serve immediately while the sauce is at its creamiest—the residual heat will continue to meld the flavors.

Each plate should feature tender shrimp nestled among the linguine with a generous coating of the lemon garlic white wine sauce.

Common Mistakes When Making Great macaroni grill shrimp portofino

Overcrowding the Pan

Trying to cook all 1.5 lb large shrimp at once is a recipe for steamed, rubbery seafood. Crowding lowers the pan temperature, causing shrimp to release moisture instead of searing. I cook in batches—2-3 minutes per side—for that perfect golden crust. 🌡️

Skipping the Deglaze

Those browned bits stuck to the pan after searing are pure flavor. Pouring 1 cup dry white wine and scraping with a wooden spoon lifts all that goodness into your sauce. Skipping this step means missing out on depth of flavor.

Overcooking the Shrimp

Shrimp cook fast—2-3 minutes per side max. They continue cooking off the heat, so pull them when they’re just opaque. Overcooked shrimp turn tough and chewy, ruining the dish’s elegance.

Sauce Separation

Adding cold ½ cup heavy cream to hot liquid can cause curdling. Temper the cream by adding a ladle of hot sauce to it first, then whisk into the pan. This keeps your sauce velvety and cohesive.

Underseasoning the Pasta

The pasta water should taste like the sea. Use 1 tsp salt in the boiling water, and

Letting It Sit

This creation is best served immediately. The sauce thickens and the pasta absorbs liquid as it sits. Plate it fresh from the pan for that restaurant-quality texture and presentation. 💫
