Moules Frites, my Home Recipe for Mussels Belgian Style

In this article, I present my version of moules frites. The original Belgian-style mussels are served with French fries.

I still have very fond memories of Belgian food since my last visit to Brussels. The fresh mussels were a feast for me! I want to have that at home too.

I don’t like deep-frying in my kitchen. That’s why I prepare the potato side dish in the oven. A homemade mayonnaise is a must at this point. I show you the entire preparation with a cooking video and many step-by-step photos.

Let’s start the preparation and conjure up a fine dish! Have fun and good luck. Feel free to write me a cooking question at the end of the article or get in touch for kitchen gossip.

1. Moules frites Recipe

If you have a deep fryer in the house, you can prepare the potato side dish from fresh potatoes as French fries. I opted for a healthier version: oven roasted potatoes. Below are the step-by-step instructions with photos. I wish you good luck!

3. Discover the speciality of moules frites

The sea creatures come to the table in Belgium with freshly prepared chips. The mussel preparation itself is not very different from the well-known mussels in white wine variant from Italian cuisine.

The crispy fries on the side are a hit! I’ve already had the pleasure of enjoying this dish in Brussels and anyone who goes there should find a decent restaurant and order the mussels.

I had the mussels served in a pot, with chips and mayo. Since it’s hard to get beef fat for frying in Germany, I made oven potatoes for my version.

Mussels and crispy potatoes, that tastes wonderful!

Side dish tip from chef Thomas Sixt
French fries are a Belgian invention. Belgian fries are deep-fried in beef fat and taste exceptionally delicious.

4. Mussels cooking tips

To be honest, I prefer to buy the seafood clean. On the mainland, the goods usually arrive in the shops already quite well and appetisingly prepared.

Nevertheless, look a bit and always wash the mussels well in cold water. Scrape the shells with a knife as needed if there are chalky bits (shells) of sea anemones stuck to the mussels.

5. How to recognise good and bad mussels?

Here is some information on how to deal with sea creatures when shopping and in your kitchen

5.1 Odour test

When unpacking, please pay attention to the smell: fresh, live mussels smell gently of the sea and seaweed.

If the mussels smell unpleasant, please do not process them. Mussel poisoning is not funny.

5.2 Shell broken

Put the mussels in cold water and wait a few minutes. Sort out mussels with broken shells immediately. The mussels open and close while lying in the water.

5.3 Mussel knock test

Slightly open (1-2 mm) is OK, the mussels should close again when tapped or when lying in cold water. It is important that the mussel is still alive.

5.4 Closed mussels after cooking

Mussels that present themselves with closed shells after cooking are not to be eaten. Mussels that are closed after cooking are not OK and must not be eaten. Please only eat the wide-open mussels!

Please only eat mussels that have been opened after cooking. Closed mussels are not edible.
