💭Tips for Recipe Success
Clean the Fish: Make sure the fish is cleaned and scaled properly. Rinse it well and pat it dry to remove any excess moisture.
Score for Flavor: Lightly score the fish with diagonal cuts on both sides. This helps it cook evenly and soak up the marinade, but don’t cut too deep to keep it intact.
Marinate for Flavor: Let the fish sit with salt, pepper, lemon, and garlic for at least 30 minutes. Rub the seasoning and olive oil into the scored cuts and cavity for even flavor.
Season the Veggies: Toss the potatoes and onions with olive oil, salt, and pepper so they roast perfectly golden and flavorful.
Layer for Flavor: Bake the potatoes and onions first to caramelize them. Then place the fish on top so its juices seep into the potatoes, adding delicious flavor.
Don’t Overcook: Keep an eye on the fish. It’s ready when it flakes easily with a fork and turns opaque.
