Fried Fish Fillets

Dijon Mustard Sauce


  • In a small, rectangular container, add coconut flour, parmesan cheese and lemon pepper seasoning. Stir well to combine.
  • Spray both sides of fish with cooking spray. Then add to parmesan mixture and coat both sides. Use fingers to press parmesan mixture into fish if necessary.
  • Add to air fryer basket and cook at 400 degrees for 10 minutes or until the fish flakes easily. I stop the air fryer halfway through cooking time to flip the fish. 

Dijon Mustard Sauce

  • In small saucepan over medium heat, add sour cream, heavy whipping cream, dijon and chives. Stir to combine and heat through but do not let it boil.
  • Spoon mustard sauce over cooked fish and serve immediately.


If you do not have an air fryer, you can broil these in the oven for 4-6 minutes. Be sure to flip them halfway through. They are done when they flake easily with a fork.
If you are not concerned with keeping it low carb, use all-purpose flour in place of the coconut flour and milk in place of the heavy whipping cream.
