Bordeaux-Style Fish Gratin (Poisson à la Bordelaise)

Fish fillets are topped with a mix of parsley, shallots cooked in white wine, lemon and breadcrumbs, and then baked in the oven until crunchy and golden – while the fish remains utterly tender underneath. This quick and simple recipe can be made with any white fish of your liking.

For the backstory, most French people recall the dish being served to them as a kid in their school cantine. The Poisson à la Bordelaise was often frozen and re-heated, and not particularly the best version of this dish.

In my school cantine, I remember the fish to be pretty bland with the crust being more soggy than crunchy. So after my school years, it’s no wonder why I almost completely forgot about this dish.

It isn’t until a few months ago that I decided to give this dish another try – but this time, homemade. I bought fresh and affordable Basa fillets and prepared the crumbly topping from scratch: with homemade breadcrumbs, fresh parsley, lemon juice and shallots cooked in white wine. What a difference!

This dish was nothing like what I remembered it to be. The baked fish remained tender and juicy, while the coarse topping turned crunchy and had fresh and tangy flavors from the parsley, white wine and lemon.

Poisson à la Bordelaise is still today a staple in the frozen aisles of French grocery stores, but I will always opt for the homemade version from now on. This recipe is easy and quick to assemble – about 20 minutes at most. It makes a perfect lunch or dinner any day of the week, accompanied by green beans, rice or potatoes.

Cooking notes:

• This recipe can be made with any white fish of your liking. For the photos here, I used four Basa filets (about 200g each – 800g total). Cod, tilapia, hake are great choices too. Whether you use fresh or frozen (then thawed) filets, make sure you pat them dry well with paper towel. You want to remove any excess moisture, or the fish will render liquid later and you will have a puddle on the bottom of your baking dish.
• Take the fish out of the fridge at least 1 hour before cooking so they warm up to almost room temperature.
• For the breadcrumbs, I like to make my own so they are chunky, as crisp as possible and salt-free. As a substitute you can use store-brought panko breadcrumbs I would avoid using regular breadcrumbs. In comparison to regular breadcrumbs, panko are dryer and have a flakier, coarser consistency. As a result, they will absorb less moisture or oil and give a crunchier crust – which is what we want for Bordeaux-Style Fish.
• For the white wine, I recommend you choose one that is dry and crisp, such as Sauvignon Blanc, Pinot Grigio, Pinot Gris or Pinot Blanc.
• The white wine gets completely evaporated when cooking with the shallots, so no alcohol is left – just flavor. This recipe is perfectly suited for the whole family – kids included.
• The baking dish I used for these photos (4 fillets – 800g total) is 8”x11” and it was perfectly sized.
