Ingredients
- 1 tablespoon unsalted butter softened
- 1 3/4 pounds white fish fillet
- 3/4 teaspoon salt
- 1/2 teaspoon pepper
- 4 teaspoons extra-virgin olive oil divided
- 1 large sweet onion thinly sliced
- 1-2 tablespoons water if needed
- 1/2 teaspoon dry thyme or 1 teaspoon fresh thyme chopped
- nutmeg to taste
- 3/4 cup dry white wine
- 2 slices bread preferably sourdough or multi-grain, crusts removed
- 1/2 teaspoon paprika
- 1/4 teaspoon garlic powder
- 1 cup Emmentaler Gruyere, or Swiss cheese, shredded
Directions
- Preheat the oven to 400 degrees F.
- Grase a 9x13-inch casserole dish with the softened butter.
- Arrange the fish in the prepared dish.
- Sprinkle the fish with the salt and the pepper.
- In a heavy skillet over medium-high heat, heat 2 teaspoons of the oil.
- Add the onion to the oil and cook, stirring often, adding 1-2 tablespoons of the water if needed to prevent the onion from browning too much, until the onion softens, about 6-9 minutes.
- Stir the thyme and the nutmeg into the onion mixture.
- Spread the onion mixture over the fish.
- Pour the wine over the casserole.
- In a food processor, pulse the bread slices until they become coarse crumbs.
- Drizzle the remaining oil over the breadcrumbs and add the paprika and the garlic powder.
- Process the breadcrumbs until the bread is evenly red and moist.
- Sprinkle the crumbs over the onion mixture.
- Evenly sprinkle the casserole with the cheese.
- Bake until the fish's internal temperature reaches 145 degrees F and the crumbs are browned, about 18-22 minutes.
- Serve warm.
