Preheat your oven to 400°F (200°C). Lightly coat the halibut fillets with olive oil, season with salt and pepper, and arrange on a baking sheet.

In a mixing bowl, combine crushed walnuts and grated Parmesan cheese. Press the mixture onto the top of each fillet.

Place the coated halibut fillets in the preheated oven and bake for 12-15 minutes.

While the halibut is baking, heat a skillet on medium, sauté finely chopped shallots until translucent, then pour in white wine and simmer for about 5 minutes.

Once baked, let the halibut rest for a minute, then plate and drizzle lemon wine sauce over each.
