Mussels in Lager

This aromatic dish of mussels in lager offers a refreshing twist on the classic marinière. By swapping traditional white wine for a crisp lager, the broth gains a subtle malty depth that pairs beautifully with the sweetness of the fresh shellfish. The addition of tinned tomatoes and celery creates a savoury, textured base, while a final swirl of double cream and Dijon mustard ensures a rich and silky finish that is perfect for soaking up with crusty bread.

As a high-protein meal, these mussels are as nutritious as they are indulgent, providing a light yet satisfying supper. This recipe is an excellent choice for a quick midweek treat or a relaxed weekend lunch with friends. Ensure you source high-quality, sustainably farmed mussels for the best flavour and texture, and remember to discard any shells that do not open during the steaming process.

How to make Mussels in Lager

Heat butter in a wide 5- to 6-quart heavy pot over moderately high heat until foam subsides, then cook onion, celery, tomatoes, garlic, thyme, bay leaf, salt, and pepper, stirring occasionally, until vegetables are softened, about 4 minutes.

Add beer and bring just to a boil. Add mussels and cook, covered, stirring occasionally, until mussels open wide, 4 to 6 minutes, transferring them to a bowl as they open. (Discard any mussels that remain unopened after 6 minutes.) Remove pot from heat. Stir together mustard and cream in a small bowl, then add mixture along with parsley to hot broth and whisk until combined. Discard bay leaf. Serve sauce over mussels.
