Ingredients

• For the Mussels & Broth:
• 2 lbs fresh mussels (farm-raised, rope-grown are ideal)
• 1 tablespoon unsalted butter
• 1 tablespoon olive oil
• 2 shallots, finely minced (or 1/2 small yellow onion)
• 3-4 cloves garlic, minced
• 1/2 cup dry white wine (such as Sauvignon Blanc or Pinot Grigio; see variations for non-alcoholic swaps)
• 1/2 cup water or low-sodium chicken/seafood stock
• 1/4 cup fresh parsley, chopped (plus more for garnish)
• 1 tablespoon fresh lemon juice (from about half a lemon)
• 1 teaspoon lemon zest
• 1/4 teaspoon red pepper flakes (optional, for a little kick)
• Salt and freshly ground black pepper to taste
• For the Fries & Dip:
• 2 large Russet potatoes (about 1.5 lbs), peeled (or scrubbed well, skins on)
• 4-6 cups neutral high-heat oil (canola, peanut, or avocado) for shallow frying, OR 2-3 tablespoons for oven baking
• 1 teaspoon kosher salt, plus more for finishing
• 1/2 cup good quality mayonnaise
• 1 tablespoon Dijon mustard
• Optional: 1/2 clove garlic, finely minced, and 1 teaspoon lemon juice for a quick aioli-style dip
• Optional But Highly Recommended:
• Crusty baguette or rustic bread, for soaking up the delicious broth

Directions

1. Prep the Potatoes & Start the Fries:
   1. Peel the potatoes (or leave skins on for a rustic touch) and cut them into 1/4 to 1/3-inch thick sticks. Aim for consistent size for even cooking.
   2. Place the cut potatoes in a large bowl and cover with cold water. Let them soak for at least 15-20 minutes (or up to a few hours in the fridge) to remove excess starch, which helps with crispness.
   3. While potatoes soak, begin the cooking method for your fries:
   4. For Oven Fries: Preheat oven to 425°F (220°C). Line a large rimmed baking sheet with parchment paper. Drain potatoes thoroughly and pat very dry with paper towels. Toss with 2-3 tablespoons neutral oil and 1 teaspoon kosher salt. Spread in a single layer, ensuring no overcrowding.
   5. For Shallow-Fried Fries: Heat 1-2 inches of neutral oil in a large, heavy-bottomed skillet or Dutch oven over medium-high heat until it reaches 325-350°F (160-175°C). Drain potatoes thoroughly and pat very dry.
   6. Begin cooking the fries using your chosen method:
   7. Oven: Bake for 20-25 minutes, flipping halfway, until lightly golden and tender. Increase heat to 450°F (230°C) and bake for another 10-15 minutes, or until deep golden brown and crispy.
   8. Shallow-Fried: Fry potatoes in batches (do not overcrowd the pan) for 4-6 minutes, until lightly golden and cooked through but not yet crisp. Remove with a slotted spoon to a wire rack set over paper towels. Let them cool slightly. This is the first fry.
2. Clean & Prep Mussels + Aromatics:
   1. While fries are cooking, prepare your mussels. Rinse them thoroughly under cold running water in a colander.
   2. Inspect each mussel: scrub any dirt or grit from the shells. If you see a "beard" (a fibrous string), pull it firmly towards the hinge end of the mussel to remove it.
   3. Discard any mussels that are cracked, chipped, or don't close tightly when tapped gently. Keep cleaned mussels in a bowl over ice with a damp towel until ready to cook.
   4. Finely mince your shallots and garlic. Chop your parsley and zest/juice your lemon.
   5. Prepare your dipping sauce: whisk together mayonnaise and Dijon mustard. If making the optional aioli-style dip, stir in minced garlic and lemon juice.
3. Finish the Fries & Keep Warm:
   1. Once your oven fries are golden and crispy, remove them from the oven and immediately season with more kosher salt to taste.
   2. If shallow-frying, increase the oil temperature to 375°F (190°C). Fry the potatoes a second time in batches for 2-4 minutes, or until deep golden brown and very crispy. Remove to a clean wire rack set over paper towels and immediately season with salt.
   3. To keep fries warm and crisp while you cook the mussels, place them on a wire rack on a baking sheet in a warm oven (around 200°F/95°C).
4. Make the Aromatic Base for Mussels:
   1. In a large, heavy-bottomed pot or Dutch oven (one with a tight-fitting lid), melt butter with olive oil over medium heat.
   2. Add minced shallots and cook, stirring occasionally, until softened and translucent (about 3-4 minutes). Do not let them brown.
   3. Add minced garlic and optional red pepper flakes, cooking for another minute until fragrant.
   Deglaze & Steam the Mussels:
   1. Pour in the white wine and increase heat to medium-high. Bring to a simmer and let it reduce for 1-2 minutes to cook off the alcohol and concentrate the flavors.
   2. Add the water or stock to the pot.
   3. Add the cleaned mussels to the pot, give them a quick stir to coat with the aromatics and liquid, then immediately cover the pot tightly with the lid.
   4. Steam for 5-7 minutes. Mussels are cooked when most of their shells have opened, and the meat is plump and opaque.
   5. Important: Discard any mussels that remain stubbornly closed after cooking.
5. Finish the Broth & Serve:
   1. Remove the pot from the heat. Stir in the fresh lemon zest, lemon juice, and chopped parsley.
   2. Taste the broth and adjust seasoning with salt and pepper as needed.
   3. Serve immediately: Ladle the mussels and their fragrant broth into large bowls. Pile the belgian french fries high in a separate bowl or a paper cone, with the mayo-Dijon dipping sauce on the side. Don't forget the crusty bread to sop up every last drop of that amazing broth!
