01 - Preheat the oven to 400°F. Lightly oil a baking tray or line it with parchment paper.
02 - Pat the hake fillets dry with paper towels and season both sides with salt and pepper.
03 - In a bowl, combine the breadcrumbs, parsley, dill, chives, lemon zest, and garlic. Add olive oil and mix until the crumbs are evenly moistened.
04 - Brush the top of each hake fillet with Dijon mustard, then press the breadcrumb mixture evenly over the top to form a crust.
05 - Place the fillets on the prepared baking tray and bake for 18-20 minutes, or until the crust is golden and the fish flakes easily with a fork.
06 - Serve immediately with lemon wedges.
