Homemade Tartar Sauce

My homemade tartar sauce recipe is keto-friendly, healthy, and the perfect sauce for so many fish recipes!

  1. Combine all tartar sauce ingredients and mix well. Can be made 1-2 days ahead of time and will keep well in the fridge for 3-4 days.
  2. Top the fish with the tartar sauce. The potatoes are great with the sauce, too! Enjoy!

Whole30 Compliant “Chips”

  1. Preheat the oven to 425. Toss potatoes with oil and spices. Spread out the potatoes, cut side down, on a parchment-lined baking sheet. Roast for 10 mins.
  2. 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 filets. Add the fish to the pan, 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 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.

FAQs

Can I make this gluten free fish and chips recipe with gluten-free beer batter? Unfortunately, not for this recipe. There are very few beers out there that are celiac safe, and beer is not compliant with Whole30. The almond flour batter I use for this fish and chips recipe is crispy and delicious, and you really won’t miss the beer batter!

Is this gluten free fish and chips recipe keto? The battered fish and tartar sauce are keto-friendly! Simply omit the potatoes in this recipe to keep the carb count low. If you’re looking for a yummy side to replace the “chips” try my keto green bean casserole!

Is fish & chips healthy? Oftentimes, it’s the batter and french fries that get fish & chips in trouble health-wise. This recipe, however, omits the fries and replaces them with roasted potatoes, which is a much healthier swap. It also uses healthier oils like olive or avocado, whereas regular fish and chips is often fried in canola oil. Likewise, the almond flour used in this recipe lowers the carb count and makes the fried fish batter so much healthier than the traditional recipe!

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!
