1-Step 1: Prep the seafood and aromatics Start by rinsing the mussels under cold running water. Scrub the shells lightly if needed, then pull off any beards. Discard any mussels that are cracked or already open and do not close when tapped. Pat the shrimp dry with paper towels so they sear better in the pan. Mince the garlic, chop the parsley, and zest and juice the lemon before you turn on the stove.

2-Step 2: Warm the butter and cook the garlic Place a large skillet over medium heat and add the 2 tablespoons of unsalted butter. Let it melt slowly, then add the minced garlic. Stir for about 30 to 60 seconds, just until the garlic smells fragrant. Keep the heat moderate so the garlic does not brown too quickly, since browned garlic can turn bitter.

3-Step 3: Deglaze with white wine Pour in the 1/2 cup of dry white wine and stir, scraping up any bits from the bottom of the pan. These little browned pieces add flavor to the sauce. Let the wine simmer for 2 to 3 minutes so the sharp alcohol flavor cooks off and the liquid reduces slightly. The pan should smell bright and savory at this stage.

4-Step 4: Add the mussels first Add the cleaned mussels to the skillet and cover with a lid. Cook for about 4 to 5 minutes over medium heat, shaking the pan gently once or twice if needed. The mussels should begin to open as they steam in the wine and garlic mixture. If some stay closed after cooking, discard them. This is an important food safety step. Transfer the opened mussels to a bowl if the pan looks crowded, or leave them in the skillet if there is enough room.

5-Step 5: Add the shrimp and cook gently Now add the 500 grams of peeled and deveined shrimp. Cook them for about 2 to 3 minutes total, turning once. The shrimp should turn pink and opaque, but still look juicy. Do not leave them on the heat too long, because shrimp can quickly become tough and rubbery. If you want to double check, cut one shrimp in the middle. It should be just opaque inside, not dry.

6-Step 6: Stir in the cream and seasonings Lower the heat to medium-low and pour in the 1 cup of heavy cream. Stir gently so the sauce turns smooth and coats the seafood. Add salt and black pepper to taste, then stir in the lemon juice and lemon zest. Let the sauce simmer gently for 2 to 4 minutes, but do not let it boil hard. A slow simmer helps the cream stay silky.

7-Step 7: Add parsley and finish the sauce Once the sauce has thickened slightly, sprinkle in the 1/4 cup of chopped fresh parsley. Taste the sauce and adjust the seasoning if needed. If you want a little more brightness, add a tiny squeeze of extra lemon juice. The sauce should taste rich, garlicky, and fresh all at once.

8-Step 8: Serve right away Spoon the shrimp and mussels into warm bowls and ladle the sauce over the top. Serve immediately while everything is hot and the sauce is at its creamiest. This dish pairs nicely with pasta, rice, garlic bread, or even roasted vegetables. The final result should look glossy and inviting, with green parsley and lemon zest adding a fresh finish.
