- 400 grams of fish fillet
- Salt and pepper to taste
- 1 lemon
- 1 red onion
- 200 grams of shrimp
- 100 grams of yellow cheese
- 1 cup of thick béchamel sauce
- 70 grams of butter
- 70 grams of wheat flour
- 500 ml of milk
- Salt, pepper, and grated nutmeg to taste
Bechamel
Season the shrimp and fish fillets with salt and pepper. For the fish, also add lemon juice. Let them marinate in this mixture for at least 2 hours.
In a deep baking dish, place half of the fish fillets. Layer the thinly sliced onions on top, then add the shrimp, followed by the grated cheese. Cover everything with the remaining fish fillets.
In a saucepan, prepare the béchamel sauce. Melt the butter over low heat, and once it's melted, add the flour. Stir with a wooden spoon and gradually incorporate the milk while continuing to stir to prevent lumps from forming. Season with salt, grated nutmeg, and ground pepper to taste. Keep cooking while stirring until it thickens to the consistency shown in the photo.
Cover the stuffed fish fillets with bechamel sauce. Bake them for 20 minutes at a temperature of 180ºC. If you want to gratin them, add grated cheese and increase the oven temperature to 220ºC during the last 5 minutes.
If you don't want them gratinated, you can finish plating by adding finely chopped parsley.
I hope you enjoy this recipe. Bon appétit!
