Oven Fries

• 1 kg russet or Maris Piper potatoes, cut into 1 cm batons
• 2 tbsp neutral oil (sunflower, canola, or grapeseed)
• 1/2–3/4 tsp fine salt, plus extra to taste
• Freshly ground black pepper (optional)

Step-by-Step Instructions

Step 1: Heat the oven and prep the fries

Preheat the oven to 230°C/450°F with a large rimmed baking sheet inside. Cut the potatoes into 1 cm batons. Soak in a large bowl of cold water for 10 minutes to remove excess starch. Drain and dry the fries thoroughly with clean towels—dry fries are crucial for crisping.

Step 2: Roast fries until golden and crisp

Toss fries with 2 tbsp neutral oil and 1/2–3/4 tsp salt. Carefully spread on the hot baking sheet in a single layer. Roast 30–35 minutes, turning and rotating the pan halfway, until deeply golden and crisp at the edges. Keep warm in the switched-off oven with the door slightly ajar.

Step 3: Clean and check the mussels

Rinse mussels under cold running water, scrubbing any grit. Pull off beards by tugging toward the hinge. Discard any with cracked shells and any that stay open after a firm tap on the counter. Keep cleaned mussels chilled under a damp towel while you cook the aromatics. Do not soak in fresh water.

Step 4: Sweat shallots and garlic

In a large heavy pot or Dutch oven (at least 6–7 liters), heat 2 tbsp butter with 1 tbsp olive oil over medium heat. Add shallots, garlic, bay leaf, thyme, a pinch of salt, and red pepper flakes if using. Cook, stirring, until the shallots are translucent and sweet but not browned, about 3–4 minutes.

Step 5: Add wine and steam the mussels

Pour in the white wine and bring to a hard boil for 1 minute to mellow the alcohol. Add the mussels, cover tightly, and cook over high heat for 5–7 minutes, shaking the pot once or twice, until most shells have opened. Remove from heat as soon as the majority open to avoid overcooking. Discard any mussels that remain closed.

Step 6: Finish with butter, cream, and herbs

Off the heat, stir in the remaining 2 tbsp butter until melted and glossy, then the cream. Return to low heat for 30–60 seconds to warm through without boiling. Stir in the chopped parsley and several grinds of black pepper. Taste and add salt if needed—the mussels are naturally briny, so season thoughtfully.

Step 7: Serve with fries, lemon, and bread

Ladle mussels and plenty of broth into warm bowls. Squeeze lemon over the top. Serve immediately with hot oven fries and warm crusty bread for dunking into the buttery, winey broth.

Pro Tips

• Choose small to medium mussels for the sweetest flavor and tender texture.
• Keep heat high while steaming so the shells open quickly without toughening the meat.
• Mount the sauce off heat with butter and cream to keep it silky and emulsified.
• Warm your bowls and bread—this keeps the broth hot and perfect for dipping.
• If your mussels release a lot of liquid, reduce the wine by an extra minute before adding them for a more concentrated broth.

Variations

• Normande: Swap wine for dry hard cider and finish with crème fraîche and a pinch of nutmeg.
• Tomato–Saffron: Add a pinch of saffron and 200 g crushed tomatoes with the wine; finish with olive oil instead of cream.
• Spicy: Stir in 1 tsp harissa or a pinch of Espelette pepper with the aromatics for gentle heat.

Storage & Make-Ahead

Live mussels can be stored up to 24–36 hours in the coldest part of the fridge, in a bowl covered with a damp towel (do not submerge in water or seal airtight). Clean just before cooking. Cooked mussels are best eaten immediately; discard any left at room temperature over 2 hours. If you must save leftovers, remove meat from shells, refrigerate in broth up to 1 day, and reheat gently until just warm—do not boil. Fries and bread are best fresh; if needed, re-crisp fries in a 220°C/425°F oven for 8–10 minutes.
