Salmon roast with cheese

Ingredients for 4 servings:

Salmon fillet 1 kg

Onion 1 head

Dijon mustard 1 tablespoon

Salt to taste

Mayonnaise 60 g

Lemon juice 2 tablespoons

Garlic 2 cloves

Grated aged cheese 30 g

Mozzarella 120 g

Ground black pepper to taste

Extra Virgin olive oil 1/2 cup

Preparation:

1. Check fish fillets for bones and, if necessary, extract them. Try to use a whole piece of salmon for this recipe.
2. Spread the fish on a baking sheet covered with foil and season with salt and pepper on both sides. Distribute thin rings of onion on top of the fish fillet.
3. In a small bowl, whisk the homemade mayonnaise with pressed garlic and lemon juice. Cover the surface of the onions with a thin layer of the resulting sauce and abundantly cover the dish with grated cheese.
4. Put the fish in a preheated to 200°C oven for 15 minutes, and then under the grill-for 2-3 minutes until a golden crust appears.
