Easy Seafood Gratin Recipe

Ingredients

2 tablespoons extra-virgin olive oil, divided
2 medium onions, very thinly sliced
1 cup dry white wine
1 1/4 pounds cod, cut into 4 pieces
2 teaspoons chopped fresh thyme
1/2 teaspoon kosher salt
1/2 teaspoon black pepper
1 1/2 cups finely chopped whole-wheat country bread (about 2 slices)
1/2 teaspoon paprika
1/2 teaspoon garlic powder
1 cup finely shredded Gruyere, or Swiss cheese

Directions

1. Preheat oven to 400°F.
2. Heat 1 tablespoon oil in a large ovenproof skillet over medium-high heat. Add onions and cook, stirring often, until just starting to soften, 5 to 7 minutes.
3. Add wine, increase heat to high and cook, stirring often, until the wine is slightly reduced, 2 to 4 minutes.
4. Place cod on the onions and sprinkle with thyme, salt and pepper. Cover the pan tightly with foil; transfer to the oven and bake for 12 minutes.
5. Toss bread with the remaining 1 tablespoon oil, paprika and garlic powder in a medium bowl. Spread the bread mixture over the fish and top with cheese. Bake, uncovered, until the fish is opaque in the center, about 10 minutes more.

Serves 4.
