There's no room for mechanically processed fish burgers here! This burger is made with a fresh cod fillet that has been baked to a crispy perfection with a light and airy batter made with buttermilk and panko. Sandwiched between a brioche bun with lettuce and cheese, these Baked Crispy Cod Burgers are the absolute best!
Preheat your oven to 450 degrees F. Line baking sheet with parchment paper and coat the surface of the paper well with cooking spray. Set aside.
Next, whisk together buttermilk, egg, salt, onion powder, garlic powder, and ground black pepper until combined. Add in the cornstarch and flour. Whisk to form a batter.
Transfer the panko crumbs to a wide shallow bowl and set aside.
Next, pat the fish dry with paper towels.
Working with one dried fish fillet at a time, dip it into the batter. Transfer to the bowl of panko. Lay the fillet flat and spoon the excess panko onto the top. Once covered, gently press the panko into the fillet with your hand. This will ensure that the panko has adhered to the fish. Lay the fillets onto the prepared baking sheet and continue until all fillet have been battered.
Generously spray the top of each fillet with cooking spray.
Place into pre-heated oven and bake for 12 minutes.
Remove from oven and use a spatula to turn the fillets over.
Return to the oven and bake for 3 more minutes. If you want a crispier, browner batter, place the fish under the broiler for a minute, but watch carefully because it will burn quickly.
Prepare the buns by spreading your sauce of choice onto both the top and bottom half of the bun.
Place a fillet of fish onto the bottom bun and immediately top with a slice of cheese, if using.
