Alaska Pollock Fillet Recipe: Flaky White Fish with Lemon-Garlic Butter

Alaska pollock shines as a versatile white fish that cooks into perfectly flaky fillets every time. This method guarantees tender results with minimal effort and maximum flavor.

The secret lies in gentle cooking and a simple lemon-garlic butter sauce that complements the fish’s natural sweetness without overpowering it. Ready in under 20 minutes with basic ingredients.

Ingredients for Alaska Pollock Fillet

Fresh pollock, bright lemon, and rich butter come together for perfectly flaky fillets.

The pollock is the star—look for wild-caught Alaska pollock at Whole Foods or Trader Joe’s (their frozen fillets are excellent). Fresh should smell like the ocean, not fishy. For the butter, Plugrá or Kerrygold give the best flavor. The lemon should be firm with vibrant skin (heavy for its size means more juice). If using frozen fillets, thaw overnight in the fridge—never at room temperature.

No white wine? Substitute chicken broth with a splash of lemon. Shallots can be swapped for red onion at half the amount. If avoiding gluten, cornstarch or almond flour works for dredging. The parsley is optional but adds freshness—dill or chives make great alternatives. For extra richness, add a pat of butter to each fillet just before serving.

Cooked fillets are best served immediately, but leftovers keep 2-3 days in the fridge. Reheat gently in a skillet with a splash of water to prevent drying. The lemon-garlic butter sauce can be made ahead and reheated—store separately for up to 1 week.

Step-by-Step Instructions for Alaska Pollock Fillets

Master these steps to create tender, flaky fish with a bright, aromatic lemon-garlic butter sauce.

Step 1: Prepare and Season the Pollock Fillets

Pat the 1.5 lb Alaska Pollock Fillets completely dry with paper towels. This removes excess moisture, ensuring a golden sear rather than steam. Season both sides evenly with the 1 tsp Kosher Salt and 0.5 tsp Freshly Ground Black Pepper.

Lightly dredge each fillet in the 0.25 cup All-Purpose Flour, shaking off any excess. The flour creates a delicate crust that locks in moisture while providing texture contrast to the flaky fish. Set the fillets aside on a plate while you prepare the pan.

Step 2: Sear the Fillets to Golden Perfection

Heat the 2 tbsp Olive Oil in a large skillet over medium-high heat until it shimmers. Add 2 tbsp Unsalted Butter and let it melt completely. The oil-butter combination gives you the high smoke point of oil with the rich flavor of butter.

Carefully place the floured fillets in the pan. Cook for 3-4 minutes per side until golden brown and crisp. The fillets are ready to flip when they release easily from the pan. Avoid moving them too soon, as this can tear the delicate fish.

Step 3: Build the Lemon-Garlic Butter Sauce

Reduce heat to medium and add the finely diced 1 whole Shallot to the pan. Sauté for 2 minutes until translucent. Add the minced 4 cloves Garlic Cloves and cook for 30 seconds until fragrant but not browned.

Pour in the 0.25 cup Dry White Wine to deglaze, scraping up any browned bits from the bottom. Let it simmer for 2 minutes until reduced by half. This step infuses the sauce with depth while balancing the acidity of the lemon.

Step 4: Finish with Lemon and Herbs

Remove the pan from heat and stir in the remaining 4 tbsp Unsalted Butter, the 3 tbsp Fresh Lemon Juice, and the 1 tsp Lemon Zest. Swirl the pan until the butter melts into a glossy, emulsified sauce.

Return the fillets to the pan, spooning the sauce over them for 30 seconds to heat through. The sauce should coat the fish lightly without overpowering its delicate flavor. Garnish with the 2 tbsp Fresh Parsley before serving.

Dietary Considerations for This Dish

Gluten-Free Option

For a gluten-free version, simply replace the 0.25 cup All-Purpose Flour with an equal amount of cornstarch or almond flour. I’ve tested both, and they create the same light, crispy coating that helps the fish hold its shape during cooking.

Dairy-Free Adaptation

To make this dish dairy-free, swap the 6 tbsp Unsalted Butter for olive oil or a plant-based butter like Miyoko’s. The flavor will still be rich and satisfying, though you may miss some of the buttery depth. The lemon and garlic shine through regardless.

Low-Carb/Keto Friendly

This recipe is naturally low-carb, with only 6 grams of net carbs per serving from the flour. For strict keto, skip the dredging entirely and season the fillets directly with salt, pepper, and a pinch of paprika for color. 💪

Pescatarian Approved

As a pescatarian staple, Alaska pollock is an excellent source of lean protein and omega-3 fatty acids. This dish fits perfectly into a seafood-focused diet, and the light sauce keeps the focus on the fish’s natural flavor.

Allergen Notes

Pollock is not a common allergen, but always check for cross-contamination if serving to someone with seafood allergies. The recipe contains no nuts, eggs, or soy, making it safe for most dietary restrictions. For nut allergies, avoid almond flour as a gluten-free substitute.

Sodium Considerations

To reduce sodium, cut the 1 tsp Kosher Salt in half and use low-sodium butter. The lemon and herbs will still provide plenty of flavor without excess salt. I often use unsalted Kerrygold for better control over seasoning. ✨
