Moules Frites: A Bistro Classic You Can Master at Home

I can still remember the first time I had Moules Frites. I was backpacking through Belgium, utterly lost in Brussels, when the aroma of the sea, garlic, and perfectly crisp potatoes wafted from a small, unassuming bistro. I ventured inside, and the sight of steaming pots of mussels being ferried to happy patrons sealed the deal. The first bite – the briny, tender mussel, the fragrant broth, and the salty, golden fry – transported me. It was more than just a meal; it was a culinary epiphany, and I’ve been chasing that perfect plate of Moules Frites ever since.

• Dietary Type: Pescatarian

Ingredients

MOULES

• 1 kg fresh mussels
• 1 large onion, peeled and finely chopped
• 1 large shallot, peeled and finely chopped
• 2 fat garlic cloves, peeled and crushed
• 1 teaspoon chopped fresh thyme
• 1 tablespoon chopped fresh flat-leaf parsley
• 1 tablespoon chopped fresh chervil
• 50 ml olive oil
• 150 ml dry white wine, such as Muscadet
• 1 teaspoon Pernod (optional) or 1 teaspoon pastis (optional)
• 2 tablespoons creme fraiche (optional)

FRITES or CHIPS

• 2 large potatoes, peeled and cut into thin strips (about 2mm x 2mm)
• 1⁄4 teaspoon salt
• Oil, for deep frying (sunflower or groundnut oil recommended)

Equipment Needed

• Large bowl
• Saucepan with lid
• Deep fat fryer or large pot for deep frying
• Slotted spoon or spider
• Paper towels
• Serving bowls

Instructions

1. Begin by preparing the frites. Slice the potatoes into thin strips (approximately 2mm x 2mm). Place the cut potatoes in a large bowl and rinse them thoroughly in salted cold water. This helps to remove excess starch, resulting in crispier frites.

2. Heat a deep fat fryer to 325°F/160°C (using sunflower or groundnut oil is preferable for its high smoke point and neutral flavor). Carefully place the frites/chips in the hot oil and cook for 4-5 minutes. They should be slightly softened but not browned. This is the first fry, which cooks the potatoes through.

3. Remove the frites/chips from the heat using a slotted spoon or spider, and place them on a wire rack or paper towels to cool completely. This step is crucial for achieving ultimate crispness. Allowing the frites to cool firms them up internally, so they don’t become soggy during the second fry.

4. While the frites are cooling, prepare the mussels. Tip the mussels into a large bowl of cold water. Rinse them thoroughly, then drain well. Remove any ‘beards’ (the fibrous threads protruding from the shell) by pulling them firmly towards the hinge of the shell.

5. Inspect the mussels carefully. Fresh mussels look black and shiny and should smell pleasantly of the sea. The vast majority should be tightly closed. Discard any mussels that smell strongly ‘fishy’, look dry, or are mostly open and do not close when tapped. These are not safe to eat.

6. In a large saucepan with a lid, place the finely chopped onion, shallot, and crushed garlic with the olive oil. Gently sweat them over a low to medium heat for about 5 minutes, or until they are softened and translucent but not browned. This allows the flavors to meld and develop a sweet, aromatic base for the mussels.

7. Add the chopped fresh thyme, parsley, and chervil to the saucepan with the softened onion mixture. If using, add the Pernod or pastis now. Stir well to combine the herbs and aromatics. The Pernod or pastis adds a subtle anise flavor that complements the mussels beautifully.

8. Add the washed and cleaned mussels to the pan. Cover the mussels with the dry white wine. Increase the heat to medium-high and bring the mixture slowly to a boil.

9. Once boiling, reduce the heat to a gentle simmer and stir occasionally. Continue cooking until the mussels have opened, discarding any that do not open. This process can take between 2 to 5 minutes, depending on the size and freshness of the mussels. Overcooking will make them rubbery, so keep a close watch.

10. If desired, stir in the creme fraiche for a richer, creamier sauce. Mix it gently through the cooked and opened mussels. Cover the pan to keep the mussels warm while you finish cooking the frites.

11. While the moules are simmering, turn up the heat of the deep fryer to 375°F/190°C. Salt the cooled frites/chips generously with salt.

12. Carefully add the frites/chips back to the hot oil for around 1 minute, or until they are golden brown and crispy. This second fry is what gives them their characteristic crunch.

13. Remove the frites from the fryer and drain them on paper towels to remove any excess oil.

14. To serve, divide the moules into deep bowls, spooning plenty of the flavorful broth over the mussels. Serve the frites/chips on the side, either in the same bowl or in a separate dish. Provide plenty of napkins and a large bowl for the discarded shells.

15. Serve immediately and enjoy!

Expert Tips & Tricks

• For extra crispy frites, after rinsing the sliced potatoes, soak them in ice water for about 30 minutes before the first fry. This helps remove even more starch.
• Don’t overcrowd the fryer when cooking the frites. Fry them in batches to maintain the oil temperature and ensure even cooking.
• If you don’t have a deep fat fryer, you can use a large, heavy-bottomed pot filled with at least 3 inches of oil. Use a thermometer to monitor the oil temperature.
• For a richer flavor in the moules, add a knob of butter along with the olive oil when sweating the onions and shallots.
• A squeeze of fresh lemon juice at the end adds a bright, acidic note that balances the richness of the dish.

Serving & Storage Suggestions

Serve Moules Frites immediately for the best flavor and texture. Leftover moules can be stored in an airtight container in the refrigerator for up to 24 hours. Reheat gently in a saucepan over low heat, adding a splash of white wine or water to prevent them from drying out. Leftover frites are best enjoyed fresh, but can be reheated in a hot oven or air fryer to restore some crispness. They will not be as good as freshly fried.

FAQs (Frequently Asked Questions)

Q: How do I know if the mussels are fresh?
A: Fresh mussels should be black and shiny, smell pleasantly of the sea, and be tightly closed. Discard any that are open and do not close when tapped.

Q: Can I use frozen mussels?
A: While fresh mussels are ideal, frozen mussels can be used in a pinch. Thaw them completely before cooking and be sure to drain off any excess liquid.

Q: What if I don’t have Pernod or pastis?
A: The Pernod or pastis is optional, but it adds a subtle anise flavor that complements the mussels well. If you don’t have either, you can omit it altogether or try a splash of anisette liqueur.

Q: How do I prevent the frites from becoming soggy?
A: The key to crispy frites is to remove as much starch as possible from the potatoes by rinsing them thoroughly in cold water. Also, be sure to cool them completely after the first fry before frying them again at a higher temperature.

Q: Can I make this dish ahead of time?
A: The frites are best enjoyed fresh, but the moules can be prepared ahead of time and reheated gently before serving.
