Steamed Maine Mussels Recipe

Rinse the mussels under cold running water. Discard any with cracked shells or that remain open after a light tap. Place mussels in a large bowl of cold water with 1 tablespoon kosher salt for 10 minutes to purge sand; lift mussels out rather than pouring to avoid reintroducing grit. Using a small knife or your fingers, pull off any beards (byssal threads) and scrub shells as needed. Drain and set aside in the refrigerator until ready to cook.

Prepare aromatics

Pat the cleaned mussels dry briefly. Finely dice the onion, shallot, and celery, mince the garlic, and strip thyme leaves from stems if desired (reserve sprigs for cooking).

In a large, heavy-bottomed pot or Dutch oven with a tight-fitting lid, heat 1 tablespoon olive oil and 3 tablespoons butter over medium heat until butter is foaming. Add the diced onion, shallot, and celery and sweat, stirring occasionally, until softened and translucent, about 5–7 minutes. Do not brown.

Add the minced garlic, thyme sprigs, bay leaf, and crushed red pepper flakes. Cook, stirring, for 30–45 seconds until fragrant.

Pour in 1 cup dry white wine and increase heat to medium-high. Bring to a lively simmer and let the wine reduce slightly, about 2 minutes, to concentrate flavor and burn off some alcohol.

Add 1/2 cup low-sodium stock and the reserved 2 cups cold water if you want extra broth (optional). Return to a simmer.

Carefully add the mussels to the pot in an even layer. Immediately cover with the lid and let steam for 5–7 minutes, shaking the pot gently once or twice during cooking to redistribute mussels. Check after 5 minutes: most mussels should be open. Continue an additional 1–2 minutes if needed but avoid overcooking (mussels that do not open after cooking should be discarded).

Using a slotted spoon or tongs, transfer opened mussels to warmed bowls, leaving broth in the pot.

To finish the broth, reduce heat to low. Stir in 2 tablespoons fresh lemon juice and 2 tablespoons heavy cream (optional) and 1 tablespoon unsalted butter. Taste and season with 1/2 teaspoon kosher salt and 1/2 teaspoon freshly ground black pepper, adjusting to taste. Remove and discard the bay leaf and thyme sprigs (if whole).

Pour hot broth over the mussels in the bowls. Scatter 1/4 cup chopped fresh parsley over each serving and add lemon wedges on the side.

Serve immediately with slices of crusty bread to soak up the flavorful broth. Encourage diners to discard any unopened mussels. Leftover broth can be strained and refrigerated for 1–2 days or frozen for later use.
