Moules-frites always brings back memories of dreaming of Parisian cafes with loved ones even when a trip is out of reach. There is something transporting about a big bowl of garlicky steamed mussels with crisp fries on the side especially when you can whip it up in just half an hour at home. The real secret is the lemon-herb aioli for dipping every fry and swipe of mussels through.
My first attempt at moules-frites was a bit intimidating but it instantly became a go-to for dinner parties Once you make it once you realize just how easy and fun it is

- Garlic: infuses the broth with aroma use only fresh not jarred for the truest flavor
- Tomato paste: lends umami and color squeeze-tube paste is convenient and flavorful

Step-by-Step Instructions
- Prepare the Lemon-Herb Aioli:
- Whisk together mayonnaise lemon zest lemon juice black pepper and chopped parsley in a bowl until completely smooth and combined This can be made while the mussels steam and is even better if chilled slightly before serving
- Cook the Aromatics:
- Melt butter in a large skillet over medium heat Add thinly sliced celery and leeks stirring often until they soften and just begin to color about four minutes Stir in fresh garlic and cook until its fragrant for about another minute which sets the foundation for the sauce
- Build the Base and Steam Mussels:
- Add tomato paste to the skillet and stir it well into the aromatics letting it caramelize for about one minute Toss in the cleaned and debearded mussels gently mixing so each shell glistens with flavor Pour in the white wine and seafood broth bringing the pan to a lively simmer Sprinkle in salt pepper and most of the parsley for a burst of herbal freshness
- Steam and Finish:
- Cover the pan tightly with a lid and allow the mussels to steam for five to six minutes Check after five minutes and discard any mussels that stay tightly closed which means they were not alive before cooking Pour any extra broth and cooked vegetables over the mussels after placing them in shallow bowls
- Serve and Enjoy:
- Immediately serve piping hot with a pile of crispy fries on the side and a generous drizzle or dollop of lemon-herb aioli Invite everyone to soak up every last drop of savory broth with fries

My favorite part is always the first dip of super crispy fries in that lemony aioli It reminds me of making this with friends after farmers market trips when we still had sand between our toes and no one wanted to spend all night in the kitchen
Storage Tips
Leftover mussels do not keep long so plan to enjoy fresh If you have extra broth or veggies they can be stored in an airtight container for up to two days Fries lose their crisp quickly so only cook what you will eat
Ingredient Swaps
No leeks on hand Sweet onion works well and maintains a gentle flavor Instead of seafood broth using extra white wine and a splash of water gives a lighter touch For fries both homemade and good frozen varieties work just bake or fry them until deeply golden
Serving Suggestions
For a light meal pair with a crisp green salad and more lemon wedges For a heartier table add crusty warm bread to soak up every bit of broth This dish also loves a glass of chilled white wine something fresh like Sauvignon Blanc

Cultural Note
Moules-frites is the unofficial national dish of Belgium but also adored all across Northern France Often served in big bowls meant for sharing it is both festive and intimate A great reminder that some of the best meals are also the simplest
