Ingredient Notes

Ingredients for gluten free fish and chips

Cod Fillets: I like to get these frozen from Costco. You can also use mahi mahi for this recipe. Any flaky white fish will work!

Ghee: This is clarified butter. You can also use butter or vegan butter. We also use olive oil for the cooking oil, but avocado oil works, too.

Eggs

Almond flour: For nut free, use a gluten free 1:1 flour.

Garlic powder

Onion powder

Baby potatoes: You can also cut russet potatoes into 1-inch chunks

Parsley: Dried or fresh

Note: Many recipes call for beer for the fish batter, but in order to keep this recipe gluten-free and Whole30, it is omitted. The gluten free fish batter still turns out AMAZING! A gluten-free beer could be used, but for this recipe we omit it completely. Many people add malt vinegar to the finished dish, but beware that malt vinegar is not gluten free. See FAQs below for more details.

Homemade Tartar Sauce

  • Mayo: I like to use Avocado oil mayonnaise!
  • Hot sauce
  • Pickles: love Grillo’s!
  • Apple cider vinegar

How To Make Gluten Free Fish & Chips

Sheet Pan Oven Method

  1. Preheat the oven to 425. Toss potatoes with oil and spices. Spread out the potatoes, cut side down, on a parchment paper-lined large roasting tray or baking sheet. Roast for 10 mins.
  2. Add the egg to a shallow bowl and beat with a fork. Add the dry ingredients: almond flour, sea salt, black pepper, and garlic powder to a separate shallow large bowl and mix well. Pat your fish dry with paper towels.
  3. Heat the 1 tbsp olive oil or avocado oil + 1 tbsp ghee in a large frying pan over medium heat. Dip each piece of cod into the egg to coat, then into the almond flour Place each piece of fish into the pan with the hot oil and cook for 2-3 minutes on each side until browned and golden perfection.
  4. Take the potatoes out of the oven and reduce the oven temperature to 400. Push the potatoes aside on the pan, making room in the middle for the fish fillets. Add the freshly fried fish to the pan in a single layer, then bake for an additional 15-20 minutes until the fish flakes when cut and the potatoes are cooked through and crispy.

Mary’s Tips & Tricks

Flour Alternative for Batter: If you prefer, you may substitute gluten-free all purpose flour for the almond flour in this recipe. Keep in mind that gluten-free flour is not Whole30 compliant. This flour will also raise the carb count, so it will no longer be keto fish & chips, but it will still be gluten-free and dairy-free.

Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, pan fry over medium heat or bake in the oven at 350F for 15-20 minutes. You can also pop it in the microwave for a 2 minutes.

Gluten Free Fish Sticks: To turn these fish fillets into fish sticks, simply cut them into stick shapes before dipping into the egg and flour mixtures. Then you will have homemade gluten free fish sticks!

Recipe FAQ’s

Is fish and chips healthy?

Usually fish and chips is battered with flour and fried in canola oil, which can make it a not-so-healthy option. However, my sheet pan gluten free fish and chips is a very balanced dinner option that is packed with protein. Baking the fish instead of deep frying it helps to cut back on fat and calories.

Can I freeze gluten free fish and chips?

I don’t recommend freezing this recipe, as fish that is battered does not reheat very well. If you have leftover fish, you can definitely freeze that and thaw it overnight in the refrigerator before you batter and fry it for this recipe!

Can Celiacs eat battered fish?

Unless it is a gluten free batter, unfortunately Celiacs cannot eat regular battered fish. Celiacs have to eat food that does not have wheat, barley, or rye.
