Inspired by classic French and Portuguese cuisines, this easy recipe for Cod with Gratin Garlic Mayonnaise brings together fresh fish, homemade aioli, and a quick gratin finish for a restaurant-quality meal at home.

Equipment
- 1 Oven-safe dish
- 1 Blender
Ingredients
- 4 fillets cod desalted
Garlic mayonnaise
- 2 cloves garlic
- 1 egg
- 1/2 tsp salt
- 1/2 tsp lemon juice
Instructions
- Cut the onion into julienne strips and the potatoes into thin slices.
- Place them in the bottom of the baking dish and drizzle a splash of oil. Then, bake for 20 minutes or until the onion and potatoes are done and golden brown.
- Meanwhile, we prepare the garlic mayonnaise or aioli. Blend slowly the garlics, the egg, the salt and the lemon juice using a blender and keeping the mixer at the bottom of the bowl until the mixture begins to thicken.
- Once the onions and potatoes are ready, put the desalted cod on top of them. Then, spread the garlic mayonnaise over the cod fillets.
- Bake it for 15 minutes at 150 degrees. The trick to obtain the crispy gratin touch is to raise the temperature to 180 degrees with heat on top during the last 5 minutes.
