Ingredients

• 2 pieces White fish fillets (cod or haddock)
• 1 cup Almond flour
• 0.25 cup Parmesan cheese, grated
• 1 teaspoon Garlic powder
• 1 teaspoon Onion powder
• 0.5 teaspoon Salt
• 0.25 teaspoon Black pepper
• 1 large Egg
• 2 tablespoons Olive oil
• 2 slices Cheddar cheese slices
• 0.25 cup Mayonnaise
• 2 tablespoons Pickle relish
• 1 teaspoon Lemon juice
• 0.25 cup Coconut flour
• 1 tablespoon Psyllium husk powder
• 4 tablespoons Water

Directions

Step 1

Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

Step 2

Pat the fish fillets dry with paper towels. Set aside.

Step 3

In a shallow bowl, mix almond flour, grated Parmesan cheese, garlic powder, onion powder, salt, and black pepper.

Step 4

In another shallow bowl, beat the egg with a tablespoon of water.

Step 5

Dip each fish fillet into the egg mixture, allowing excess to drip off, then coat well in the almond flour mixture. Press lightly so the coating adheres.

Step 6

Heat olive oil in a large skillet over medium heat. Cook the fillets for 2-3 minutes on each side until golden and crispy. Transfer to the prepared baking sheet and place a slice of cheddar cheese on top of each fillet.

Step 7

For the low-carb buns, mix coconut flour, psyllium husk powder, a pinch of salt, and the remaining water in a bowl. Shape the mixture into two bun-sized rounds. Place on a separate lined baking sheet.

Step 8

Bake fish and buns in the preheated oven for 10 minutes, until fish is cooked through and cheese is melted, and the buns are firm to the touch.

Step 9

In a small bowl, combine mayonnaise, pickle relish, and lemon juice to make the tartar sauce.

Step 10

Assemble each sandwich by placing a cheesy fish fillet between two low-carb buns, spreading generously with tartar sauce.

Step 11

Serve immediately, enjoying the classic taste with a low-carb twist.
