Place the cod fillets in a dish and coat with the juice of ½ a lemon. Cover and marinate in the fridge overnight for enhanced flavor.
Set the oven to 375°F (190°C). Line a baking sheet with parchment paper or lightly grease it.
In a medium bowl, whisk together the egg, salt, and pepper. In a separate bowl, place the almond meal.
Dip each cod fillet into the egg mixture, ensuring an even coat. Then, dredge in the almond meal, pressing gently to help it adhere.
Place the coated fillets on the prepared baking sheet and bake for 20 minutes, or until the cod reaches an internal temperature of 145°F (63°C) and flakes easily with a fork.
Remove from the oven and sprinkle with slivered almonds for extra crunch.
Plate with a side of roasted vegetables or a light salad.
Notes
Cooking Tip: For extra crispiness, lightly spray the coated cod with oil before baking or broiling for 1–2 minutes.
Pairing Suggestions: Serve with roasted asparagus, Brussels sprouts, or a fresh lemon-garlic sauce for extra flavor.
