Preheat oven to 425 degrees F and line a large baking sheet with parchment paper.
Whisk together the egg, water, and stone ground mustard in a bowl until well-combined.
In a mixing bowl, stir together the almond flour, sea salt, dried oregano, and thyme until well-combined.
Dredge each salmon fillet in the egg mixture, then transfer it to the almond-herb mixture. Use your hands to coat the whole surface of the fish in the almond mixture.
Transfer the fillets to the parchment-lined baking sheet and bake in the preheated oven 15 to 20 minutes, or until salmon is cooked through and crispy.
Serve almond crusted salmon with lemon wedges and your choice of side dishes and enjoy.
