Ingredients

Instructions

  1. Step 1: Scrub mussels under cold running water, removing beards. Discard any open mussels that don't close when tapped. Place mussels in a large pot with 120 ml dry white wine, 2 minced garlic cloves, and 1/2 tsp salt. Cover tightly and cook over medium-high heat for 5-7 minutes until shells open, shaking the pot occasionally.
  2. Step 2: While mussels cook, trim leeks, slice thinly, and mince 1 garlic clove. Melt 10 g butter in a small saucepan over medium heat, add leeks, and cook for 4 minutes until softened but not browned.
  3. Step 3: Remove mussels from pot with a slotted spoon, discarding any unopened shells. Strain cooking liquid through a fine-mesh sieve into the saucepan with leeks, discarding solids.
  4. Step 4: Add 60 ml heavy cream to the strained liquid, then stir in remaining 10 g butter, 1 tbsp lemon juice, 1/4 tsp black pepper, and 2 tbsp chopped parsley. Simmer for 2 minutes until slightly thickened and heated through.
  5. Step 5: Return mussels to the saucepan and toss gently to coat. Cook for 1 minute more, then serve immediately in a bowl with crusty bread for dipping.

How do I store leftover Brussels-Style Mussels with Leek and White Wine?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep mussels from drying out.

Can I substitute ingredients in Brussels-Style Mussels with Leek and White Wine?

Yes — most ingredients in this recipe have flexible swaps. For oil, use any neutral high-smoke-point oil (avocado, grapeseed, refined coconut). For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Brussels-Style Mussels with Leek and White Wine for a different number of people?

The recipe is written for 2 servings. Multiply each ingredient by (your serving target / 2). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
