Preheat your oven to 400F.
Place fillets onto a plate and pat each fish fillet dry with a kitchen towel or paper towels. Set aside.
2 large fresh halibut fillets
Line a rimmed baking sheet with, parchment paper, drizzle it with olive oil and place your halibut fillets on it. Make sure to place fish 1-2 inches apart. Sprinkle sea salt and ground black pepper over all of the fillets. Set aside while you make the butter topping.
1/4 teaspoon Sea Salt, 1/4 teaspoon Black Pepper
In a small bowl combine the softened butter with lemon juice, minced garlic and salt. Once it is well mixed, spread evenly over all of the halibut fillets including the side of the fish. Getting it on the sides of the fillet help seal in the moisture. Set aside while you make the almond flour mixture.
1/4 cup butter, 1/2 Tablespoon Lemon Juice, 1/2 Tablespoon fresh Garlic; minced, 1/8 teaspoon salt
In a wide shallow bowl combine the almond flour, salt and pepper, plus paprika. Stir well then gently spoon the almond flour mixture over each filet, being mindful of keeping it on top as best as you can.
5 Tablespoons Almond flour, 1/4 teaspoon Sea Salt, 1/4 teaspoon Black Pepper, 1/4 teaspoon Paprika
Once the fillets are covered in the almond flour mixture completely, bake 5 minutes at 400F.
Now turn the oven to HIGH BROIL and broil fillets for 4 minutes until golden brown. Check the fish at regular intervals while baking to prevent overcooking.
If your halibut fillets are thicker, you may need 5 minutes, but no more or the fish will become tough and ruined. If you find that some fillets are done before the others, remove them from the pan as to not overcook.
A kitchen thermometer should read the internal temperature as 130°F to 135°F. Gently flake with a fork to test for doneness.
Keep any leftover fillets in an airtight container up to 2 days. Reheat in the oven on very low heat 8-10 minutes wrapped in a foil packet or oven-safe frying pan with a lid. Be careful when removing the lid or opening the packet as you let the steam escape.
