Essential Ingredient Notes for Success

Selecting the right ingredients is key to the success of this healthy fish and chips recipe. Here’s a closer look at what you’ll need:

Cod Fillets: High-quality white fish is paramount for authentic flavor and texture. Cod is an excellent choice due to its firm yet flaky texture and mild taste, making it perfect for battering and baking. You can often find great frozen cod fillets at stores like Costco. Alternatively, other flaky white fish such as mahi-mahi, haddock, or even tilapia can be used. Ensure your fillets are thawed thoroughly if frozen and patted very dry to help the batter adhere properly.

Ghee: Clarified butter, or ghee, is a fantastic dairy-free option that provides a rich, buttery flavor with a high smoke point, ideal for pan-frying the fish before baking. If ghee isn’t available or preferred, regular butter works if dairy isn’t an issue. For a strictly vegan option, opt for a high-quality vegan butter. We also use olive oil or avocado oil for roasting the potatoes and light pan-frying, both of which are heart-healthy choices.

Eggs: Essential for creating the base for our gluten-free batter, helping the almond flour mixture stick to the fish fillets and ensuring a crispy crust.

Almond Flour: This provides a wonderful gluten-free, low-carb alternative to traditional wheat flour in the batter, contributing to the dish’s keto and Whole30 compliance. For those with nut allergies, a gluten-free 1:1 all-purpose flour blend can be substituted, though it will alter the carb count and Whole30 compliance. Ensure your chosen blend is suitable for frying/baking.

Garlic Powder & Onion Powder: These pantry staples are crucial for seasoning both the fish batter and the potatoes, adding a savory depth of flavor that elevates the entire dish.

Baby Potatoes: Small, tender baby potatoes (any color) are ideal for roasting, offering a delightful creamy interior and crispy skin. They require minimal prep, often just a quick wash and halving. If you don’t have baby potatoes, russet potatoes cut into uniform 1-inch chunks will also yield excellent results for your homemade chips.

Parsley: Fresh or dried parsley adds a touch of herbaceous freshness to the roasted potatoes, enhancing their overall flavor profile. Fresh parsley also makes for a beautiful garnish.

Important Note on Traditional Ingredients: Many classic fish and chips recipes incorporate beer into the batter for a light, airy texture, and malt vinegar is often drizzled over the finished dish. However, to keep this recipe strictly gluten-free and Whole30 compliant, we omit beer entirely. While gluten-free beer is an option for some, our almond flour batter still achieves an incredibly delicious and crispy result without it. It’s also vital to remember that traditional malt vinegar is NOT gluten-free, as it’s derived from barley. For a gluten-free tang, a squeeze of lemon juice or apple cider vinegar makes a great substitute. See our FAQ section below for more details on gluten-free considerations.

Homemade Tartar Sauce Ingredients

Our homemade tartar sauce is a highlight of this recipe, perfectly balancing the richness of the fish and chips with its tangy, creamy profile. It’s also keto-friendly and incredibly healthy!

• Mayo: Choose an avocado oil mayonnaise for a Whole30 and healthy fat-friendly option. Sir Kensington’s Avocado Oil Mayo is a great choice as it’s now sugar-free.
• Hot Sauce: A dash of hot sauce (like Frank’s Red Hot) adds a subtle kick and depth of flavor, making the sauce more dynamic.
• Pickles: Finely diced pickles provide that essential briny, tangy crunch. Grillo’s pickles are a personal favorite for their crispness and flavor.
• Apple Cider Vinegar: Adds an extra layer of bright acidity, rounding out the sauce’s flavor profile.

How To Craft Your Gluten-Free Fish & Chips

Get ready to create a masterpiece! Here’s a detailed guide to preparing your delicious and healthy fish and chips, including both oven-baked and air fryer methods.

Sheet Pan Oven Method for Crispy Perfection

1. Prepare the Oven and Potatoes: Begin by preheating your oven to a robust 425°F (220°C). While the oven heats, toss your halved baby potatoes (or 1-inch russet chunks) with 1 tablespoon of olive oil or avocado oil, ½ teaspoon sea salt, 1 teaspoon garlic powder, and 1 teaspoon dried parsley until evenly coated. Spread the seasoned potatoes out in a single layer, cut-side down, on a large baking sheet lined with parchment paper. This ensures maximum crispiness. Roast the potatoes for an initial 10 minutes.
2. Prepare the Fish Batter: While the potatoes are roasting, set up your dredging stations for the fish. In a shallow bowl, whisk one egg vigorously with a fork. In a separate shallow, larger bowl, combine ½ cup almond flour, ½ teaspoon sea salt, ¼ teaspoon black pepper, 1 teaspoon garlic powder, and 1 teaspoon onion powder, mixing thoroughly. Ensure your cod fillets are thoroughly patted dry with paper towels; this is a crucial step for the batter to adhere well.
3. Pan-Fry the Fish: Heat 1 tablespoon of olive or avocado oil and 1 tablespoon of ghee in a large skillet (cast iron works wonderfully for this) over medium heat. Once hot, dip each piece of cod fillet first into the beaten egg, allowing any excess to drip off, then transfer it to the almond flour mixture, pressing gently to ensure a full and even coating on all sides. Carefully place the battered fish fillets into the hot skillet. Cook for 2-3 minutes per side, just until they turn beautifully golden brown and start to crisp up. This initial pan-fry locks in flavor and creates a superior crust before baking.
4. Bake Together for a Grand Finish: Remove the potatoes from the oven and reduce the oven temperature to 400°F (200°C). Gently push the partially roasted potatoes to one side of the baking sheet, creating space in the middle for your pan-fried fish fillets. Arrange the fish in a single layer on the cleared section of the baking sheet. Return the entire sheet pan to the oven and bake for an additional 15-20 minutes. The fish is done when it easily flakes with a fork and reaches an internal temperature of 145°F (63°C), and the potatoes should be tender on the inside and wonderfully crispy on the outside.

Air Fryer Fish and Chips: For Extra Crispiness

For an even crispier texture with minimal oil, the air fryer is a fantastic option for the fish fillets.

1. Prepare and Batter the Fish: Follow the same steps as the oven method for patting the fish dry and dipping it first in the egg wash, then coating evenly with the almond flour batter mixture.
2. Air Fry: Lightly spray the air fryer basket with olive or avocado oil spray to prevent sticking. Carefully place your battered fish fillets in a single layer in the basket, ensuring they are not overcrowded for optimal air circulation. You may need to cook in batches.
3. Cook to Golden Perfection: Air fry at 400°F (200°C) for 10-13 minutes, flipping halfway through, or until the fish is golden brown, crispy, and cooked through, reaching an internal temperature of 145°F (63°C).

Whip Up the Homemade Tartar Sauce

This simple yet flavorful homemade tartar sauce is the perfect accompaniment, offering a creamy, tangy, and slightly spicy counterpoint to your crispy fish and chips.

1. Combine Ingredients: In a small bowl, combine all tartar sauce ingredients: ½ cup compliant mayo, 1.5 tablespoons hot sauce, 1 large pickle (finely diced), and 1 teaspoon apple cider vinegar. Mix thoroughly until well combined.
2. Chill and Serve: For best results, allow the tartar sauce to chill in the refrigerator for at least 30 minutes before serving to let the flavors meld. This sauce can be prepared 1-2 days in advance and stored in an airtight container in the fridge for up to 3-4 days.
3. Enjoy! Generously top your freshly cooked fish and chips with this delightful tartar sauce. It’s also fantastic for dipping the crispy potatoes!

Expert Tips & Tricks for Perfect Results

Achieving the best gluten-free fish and chips is easy with these helpful tips:

Flour Alternative for Batter: While almond flour is excellent for Whole30 and keto diets, you can substitute a gluten-free all-purpose flour blend for the almond flour. Be aware that most gluten-free all-purpose flours are not Whole30 compliant and will increase the carbohydrate count, meaning the recipe will no longer be keto-friendly. However, it will remain deliciously gluten-free and dairy-free.

Achieving Crispy Potatoes: For truly crispy chips, ensure your potatoes are spread in a single layer on the baking sheet and not overcrowded. Overcrowding steams the potatoes instead of roasting them. Flipping them once or twice during cooking also helps achieve an even crispness. Don’t be shy with seasoning the potatoes either – a good blend of salt, garlic powder, and parsley makes all the difference.

Selecting the Best Fish: Always opt for fresh or properly thawed and dried fish fillets. Moisture is the enemy of crispiness, so thoroughly patting your fish dry with paper towels before dredging is a non-negotiable step. The thicker the fillet, the longer it might take to cook, so aim for fillets of similar thickness for even cooking.

Storage & Reheating: Leftover fish and chips can be stored in an airtight container in the refrigerator for up to 3 days. While fried/battered fish can sometimes lose its crispness upon reheating, you can largely restore it. For best results, reheat by pan-frying over medium heat for a few minutes per side or baking in the oven at 350°F (175°C) for 15-20 minutes until heated through and crispy. The microwave is a quick option (about 2 minutes) but won’t achieve the same crisp texture.

Transform into Gluten-Free Fish Sticks: This recipe is easily adaptable to make homemade gluten-free fish sticks! Simply cut your cod fillets into uniform stick shapes (about 1×3 inches) before dipping them into the egg and flour mixtures. Adjust cooking times slightly shorter as the pieces will be smaller, ensuring they are golden and cooked through.

Don’t Forget the Lemon: A squeeze of fresh lemon juice over the finished dish adds a bright, zesty counterpoint that perfectly complements the rich flavors of the fish and tartar sauce.
