Rockfish fillets brushed with a savory gochujang mayo glaze, topped with panko and sesame seeds, and broiled until golden and flaky in under 10 minutes.
Set your oven to low broil and position the rack about 6 inches from the broiler.
Pat 6 rockfish fillets completely dry with a paper towel and lay them out on the prepared sheet pan. Don't skip this step -- moisture is what prevents the glaze from adhering properly.
In a small bowl, stir together ⅓ cup mayonnaise, 3 tablespoons gochujang paste, and 1 ½ tablespoon soy sauce or tamari until smooth. Using a pastry brush, spread the glaze evenly over the top of each fillet only. Go all the way to the edges but it's not necessary to get the underside.
Sprinkle 1 cup panko breadcrumbs generously over each glazed fillet, followed by a scatter of 2 tablespoons white sesame seeds. No pressing needed -- the glaze holds everything in place.
Broil on low for 6 to 8 minutes, keeping a close eye after the 5 minute mark. The panko should be golden and the fish should flake easily at the thickest part when done. No flipping needed.
Notes
Storage: Best straight off the pan when the panko is at its crispiest. Leftovers keep in the fridge for up to 2 days. To reheat, use a 375°F oven for 6 to 8 minutes. Helpful Tips:
Broil not bake: Low broil is intentional here. High broil will burn the panko before the fish has a chance to cook through, especially on thin fillets. Keep it low and watch it closely those last few minutes.
Adjust the heat: Gochujang brings real heat at 3 tablespoons. If you're cooking for kids or anyone spice-sensitive, start with 1 to 1 ½ tablespoons. You can always serve extra gochujang on the side for those who want more.
Don't overcook fish: Overcooked fish is dry and rubbery -- pull it the moment it flakes. Thin fillets move fast under a broiler.
