Crispy Fish Nuggets

  • Author: Kyndra Holley
  • Total Time: 32 minutes
  • Yield: 4 servings 1x
  • Diet: Gluten Free


These Crispy Fish Nuggets are not the frozen fish sticks of your youth. They are breaded with a low carb, gluten free breading, seasoning with lemon pepper, air-fried until perfectly crispy and then served with a deliciously savory tartar sauce recipe. Best of all, they only have 5 ingredients and can be made in under 30 minutes.

  1. Preheat the air fryer or convection oven to 400°F. Spray a rimmed baking sheet or the tray of your air fryer with spray avocado oil. Alternatively, you can use a paper towel to grease the baking sheet or tray with a little avocado oil. (If you are using an air fryer with a basket, spray both sides of the breaded fish nuggets before putting them into the basket.)
  2. Pat the cod fillets dry and season with the lemon pepper seasoning. Cut into 1 1/2 inch chunks. 
  3. Set up 3 shallow bowls. Add the coconut flour to the first bowl, eggs and water to the second bowl, and the breading to the third bowl. Use a fork to whisk the eggs and water together. 
  4. Coat a piece of cod in the coconut flour, then dredge it in the egg wash, then coat it in the breading mixture. Repeat this process with all of the cod pieces. 
  5. Place the breaded cod on the prepared baking sheet. If you are using the cooking spray, lightly spray the tops of the nuggets. 
  6. Bake at 400°F, on the middle rack for 10 to 12 minutes (if using a convection oven). Cook on broil for an additional 2 minutes or until they are crispy and golden brown. If you are using an air fryer with a basket, gently place the breaded nuggets into the basket and cook for 10 to 12 minutes. If you are using a toaster oven /air fryer combo, place the breaded cod on the prepared air fryer tray and cook for 10 to 12 minutes. 
  7. Serve with tartar sauce and fresh lemon slices.

  • If your oven has a convection setting or a true convection setting, this is the same as air frying. Using one of these settings will get your nuggets nice and crispy. 
  • If you do not like coconut flour, or you are allergic, you can omit it. However, it does help the breading stay on.
