The Halibut That Changed Everything
I wasn’t always a fish enthusiast. Growing up in the Midwest, our fish came in two varieties: fish sticks or “Friday night special” at the local diner. It wasn’t until a coastal vacation where I tasted properly prepared halibut that my perspective completely changed. The chef had created this parmesan crust that was so divine, I practically begged for the recipe. This keto adaptation has become my go-to impressive-yet-simple dinner party main that never fails to elicit recipe requests.

Ingredients
For the halibut:
- 4 halibut fillets (6 oz each), skin removed
- ¾ cup finely grated parmesan cheese
- 2 tablespoons almond flour
- 1 teaspoon garlic powder
- 1 teaspoon dried dill
- ½ teaspoon paprika
- ½ teaspoon sea salt
- ¼ teaspoon freshly ground black pepper
- 2 large eggs, beaten
- 3 tablespoons olive oil
- 1 tablespoon butter
For the lemon dill sauce:
- ½ cup mayonnaise (full-fat)
- 2 tablespoons sour cream
- 2 tablespoons fresh dill, finely chopped
- 1 tablespoon lemon juice
- 1 teaspoon lemon zest
- 1 small garlic clove, minced
- ¼ teaspoon sea salt
- Pinch of white pepper
For garnish:
- Fresh dill sprigs
- Lemon wedges
- Extra virgin olive oil (optional drizzle)
Instructions
Prep the fish: Pat the halibut fillets completely dry with paper towels. This is crucial for achieving a crispy crust. Season lightly with salt and pepper on both sides.
Make the parmesan coating: In a shallow dish, combine the parmesan cheese, almond flour, garlic powder, dried dill, paprika, sea salt, and black pepper. Mix thoroughly.
Set up your station: Place the beaten eggs in a separate shallow dish. Arrange your workstation in this order: fish fillets, egg wash, parmesan mixture, and finally a clean plate for the coated fillets.
Coat the fish: Dip each fillet into the beaten eggs, allowing excess to drip off, then press into the parmesan mixture, ensuring an even coating on all sides. Place on the clean plate.
Prepare the sauce: While the coated fish rests, combine all sauce ingredients in a small bowl and whisk until smooth. Refrigerate until ready to serve.
Cook the fish: Heat olive oil and butter in a large non-stick skillet over medium-high heat until shimmering but not smoking. Carefully place the coated fillets in the pan, working in batches if necessary to avoid overcrowding.
Achieve the perfect crust: Cook the fillets for 3-4 minutes on the first side without moving them, until the bottom is golden brown and crispy. Carefully flip once and cook for an additional
2-3 minutes until the fish reaches an internal temperature of 135°F (57°C) and flakes easily with a fork.Rest briefly: Transfer the cooked fillets to a paper towel-lined plate and let rest for 1-2 minutes to allow any excess oil to drain.
Serve: Place each fillet on a warmed plate, add a generous dollop of the lemon dill sauce, and garnish with fresh dill sprigs and a lemon wedge. For an extra touch of luxury, drizzle with a small amount of high-quality extra virgin olive oil.
Tips and Variations
For the perfect crust:
- Don’t skip patting the fish dry—moisture is the enemy of crispiness.
- Let the coated fish rest for 5 minutes before cooking to help the coating adhere better.
- Use a fish spatula for flipping to maintain the integrity of the crust.
Fish substitutions:
- This technique works beautifully with other firm white fish like cod, sea bass, or mahi-mahi.
- For a more budget-friendly option, try wild-caught pollock or haddock.
Flavor variations:
- Mediterranean: Add 1 teaspoon of dried oregano to the crust and capers to the sauce.
- Spicy: Incorporate a pinch of cayenne into the parmesan mixture and a dash of hot sauce in the dressing.
- Herb-forward: Use fresh herbs like basil and parsley in addition to dill in both the crust and sauce.
Serving suggestions:
- Pair with roasted asparagus or a simple arugula salad dressed with lemon and olive oil.
- For a complete meal, serve alongside cauliflower rice or mashed cauliflower.
