Low Carb Fried Fish with Dijon Mustard Sauce

Sharing is caring!

Last updated on March 30th, 2023

I made this fried tilapia recipe in my air fryer , but it could also be easily be baked in an oven or fried on the stove top! It’s an incredibly versatile recipe that you can tweak until you get your favorite blend of seasonings and cooking method. The dijon mustard sauce has a  mild mustard taste that brings the whole dish together

This was one of those recipes that surprised me with how much I ended up loving it! I originally was just trying to come up with a quick, low-carb fish recipe that I could make in my air fryer. I know most people find tilapia pretty bland, though, so I wanted an easy sauce to serve it with.

For some reason, the combination of milk fish with milk sauce makes for an amazing dish! It really lets the parmesan in the crust shine through, and it all just pairs so perfectly together!

Bonus points because it’s a great low-carb dinner option that’s perfect for people following the keto way of eating or just those who are trying to stay healthy!

How to Make Fried Fish in the Air Fryer

I was a little worried that the fish would cook too quickly in the air fryer and be chewy once I pulled it out. It was perfectly flaky, though, and just exactly how you want your fish to turn it out. Air frying fish was definitely a success!

I started with thawed tilapia fillets that were about 1/2″ thick. You may have to adjust how long you cook it based on how thick your fish fillets are, but it shouldn’t be too big of a difference. I did not test air frying frozen fish fillets, but if you do, leave me a note to let me know how it goes!

In a small rectangular container, add 1/4 cup of coconut flour, 1/4 cup of parmesan cheese, and 1/2 teaspoon of lemon pepper seasoning. Stir it together until it’s well blended.

Using cooking spray, lightly spray both sides of your tilapia fillets to coat them. Then dip in parmesan mixture and flip to coat opposite side as well. You might have to use your fingers to really press the coating on.

Add to air fryer pan and cook for 10 minutes at 400 degrees. You know your fish is done when it flakes easily with a fork.

While your fish is in the air fryer, this is the perfect time to make your Dijon Mustard Sauce!

To serve, plate your fried fish and spoon the dijon mustard sauce over the top. You can sprinkle with additional chives if you want but that’s completely optional.

Tips and Tricks to Making Fried Fish

• If you aren’t concerned with keeping your dinner low carb, there are a couple of substitutions you can make. Use all-purpose flour instead of coconut flour. Use milk instead of heavy whipping cream.
• You can also bake these in the oven if you don’t have an air fryer. Preheat your oven to broil and set the rack to the highest position. Broil the coated fish for about 4-6 minutes depending on the thickness of your fish. Turn over halfway through cooking. Fish is done when it flakes easily.
• If you don’t have lemon pepper seasoning , you can just add salt and pepper to taste to the low-carb breading mix before you coat the fish.
• The Dijon Mustard Sauce works really well with pork chops and chicken as well!
