Ingredients

Instructions

  1. Step 1: Scrub 2 lbs mussels under cold running water, removing any beards and discarding any that are cracked or open. Discard any that don't close when tapped.
  2. Step 2: Heat 3 tbsp olive oil in a large Dutch oven over medium-high heat. Add 2 medium thinly sliced leeks and 3 minced garlic cloves, sautéing for 3 minutes until softened but not browned.
  3. Step 3: Add 1 cup Belgian blonde ale and 1/2 cup dry white wine, bringing to a simmer and scraping up any browned bits. Add 2 lbs cleaned mussels, cover tightly, and cook for 5-7 minutes until all mussels have opened, shaking the pot occasionally.
  4. Step 4: Discard any mussels that remain closed. Stir in 2 tbsp fresh thyme leaves and cook uncovered for 1 minute more until fragrant. Remove from heat and stir in 2 tbsp chopped fresh parsley.
  5. Step 5: Serve immediately in a bowl with toasted baguette slices for dipping.
