Crispy Fish with Brown Butter Sauce and Kohlrabi Salad

This elegant pan-fried fish dish combines sophisticated textures with vibrant, fresh flavours. The heart-healthy recipe uses sea bass or salmon fillets, paired with a bright kohlrabi and apple salad that provides a refreshing crunch against the richness of the fish. By starting the fish in a cold frying pan, you achieve a perfectly even, gold-standard crispness on the skin without overcooking the delicate flesh beneath.

Suitable for a nutritious midweek meal or a light weekend dinner, this dish is elevated by a simple yet luxurious hazelnut brown butter sauce. The combination of toasted nuts and citrus ensures a well-balanced plate that feels indulgent while remaining light. Serve it with extra lemon wedges to cut through the buttery sauce for a restaurant-quality finish at home.

  • 60ml plus 2 teaspoons fresh lemon juice

  • 45ml extra-virgin olive oil, divided

  • 1 teaspoon kosher salt, plus more

  • 2 small kohlrabi, peeled, halved lengthwise, thinly sliced crosswise

  • 1 large green apple, cut into quarters lengthwise, thinly sliced lengthwise

  • 1/2 red onion, thinly sliced

  • 4 (5–170g ) skin-on Chilean sea bass or salmon fillets

How to make Crispy Fish with Brown Butter Sauce and Kohlrabi Salad

Whisk honey, 60ml lemon juice, 2 tablespoons oil, and 1 teaspoon salt in a large bowl. Add kohlrabi, apple, and onion and toss to coat. Let sit while you cook the fish.

Swirl remaining 1 tablespoon oil in a large nonstick skillet to coat. Season fish generously on both sides with salt and pepper and place, skin side down, in cold skillet. Set over medium heat and cook until fat starts to cook out of fish, about 4 minutes. Gently press on fillets with a spatula so skin makes good contact with pan, then keep pressing, cycling from one fillet to the next every few seconds, until skin starts to crisp. Continue to cook without pressing until skin is super crisp and flesh is mostly opaque, 8–10 minutes total (adjust heat as needed, but don’t rush it). Turn over; cook until completely opaque, about 1 minute. Place skin side up on plates.

Wipe out skillet and return to medium heat. Cook hazelnuts and butter, swirling pan often, until butter foams, then browns, about 4 minutes. Remove from heat and stir in remaining 2 teaspoons lemon juice; season brown butter sauce with salt and pepper.

Toss kohlrabi salad and serve alongside fish fillets, leaving excess dressing behind. Spoon brown butter sauce over fish and salad and serve with lemon wedges for squeezing over.
