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

Step 5 -In a heavy skillet over medium-high heat, heat 2 teaspoons of the oil.
Step 6 -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.

Step 8 -Spread the onion mixture over the fish.
Step 9 -Pour the wine over the casserole.
Step 10 -In a food processor, pulse the bread slices until they become coarse crumbs.

Step 12 -Process the breadcrumbs until the bread is evenly red and moist.
Step 13 -Sprinkle the crumbs over the onion mixture.
Step 14 -Evenly sprinkle the casserole with the cheese.
Step 15 -Bake until the fish's internal temperature reaches 145 degrees F and the crumbs are browned, about 18-22 minutes.
Step 16 -Serve warm.
