30-Minute Walnut-Crusted Halibut
Pan-seared halibut fillets encased in toasted walnut crust, finished in the oven and drizzled with a sweet-salty honey-soy reduction. The nutty exterior contrasts with the delicate, flaky white fish, while the glaze adds depth and umami. Elegant enough for entertaining, simple enough for weeknight dinners. This version balances the richness of walnuts with bright soy and clover honey for a restaurant-quality dish.

Tips
Chill coated fillets for 10 minutes before cooking to help the walnut crust adhere better and prevent flaking during the sear.
Don't skip the 5-minute rest after coating; it allows the egg wash to set and secure the walnuts.
Use a non-stick or well-seasoned pan to prevent the walnut crust from sticking; avoid moving the fish until the first side is golden.
Good to Know
Refrigerate coated fillets up to 4 hours before cooking. Store leftover sauce covered for up to 5 days.
Chop walnuts and mix sauce 1 day ahead. Coat fillets up to 4 hours before cooking; keep refrigerated.
Serve immediately while crust is crisp and fish is warm. Pair with roasted asparagus, steamed broccoli, or a light rice pilaf. A crisp Sauvignon Blanc or mineral Pinot Grigio complements the dish well.
Common Mistakes
Overcook fish to avoid dry, flaky texture; remove from oven when thickest part is just opaque (5 minutes is approximate; check for doneness).
Don't skip the flour layer to avoid egg wash dripping off during cooking.
Avoid low heat to prevent the walnut crust from burning before the interior cooks through.

FAQ
Can I make this ahead of time?
Coat the fillets up to 4 hours ahead and refrigerate. Don't cook until just before serving, as the crust loses its crisp texture when stored cooked. The sauce keeps for 5 days refrigerated and can be reheated gently.
What if my fish cooks too quickly or too slowly?
Oven time varies by fillet thickness and oven accuracy. Thinner fillets (under 1 inch) may need only 3-4 minutes; thicker ones up to 7 minutes. Check for opaque flesh at the thickest point. Reduce pan heat slightly if crust browns too fast.
How long can I keep leftover halibut?
Store cooked fish in an airtight container for up to 2 days. The crust will soften; reheat gently in a 300F oven for 5-7 minutes to restore crispness. Sauce lasts up to 5 days refrigerated.
