Baked Flounder with Roasted Tomatoes

Here Dijon mustard serves a dual purpose: It flavors the delicate fish, and helps the bread-crumb coating stay in place as the fish cooks. Tilapia can be used in place of flounder.

Recipe information

  • Yield

    serves 4

Ingredients

6 plum tomatoes, halved lengthwise
2 tablespoons olive oil, plus more for baking sheet
3/4 teaspoon dried tarragon or dried oregano
Pinch of sugar
Coarse salt and freshly ground pepper
1/3 cup mayonnaise
1 tablespoon fresh lemon juice
3 slices white sandwich bread, torn into large pieces
4 flounder fillets (1 1/2 pounds)
2 tablespoons Dijon mustard

Preparation

  1. Step 1

    Preheat oven to 450°F, with racks in upper and lower thirds. Place tomatoes on a rimmed baking sheet. Drizzle with 1 tablespoon oil, and sprinkle with 1/4 teaspoon tarragon and the sugar; season with salt and pepper. Toss to coat. Arrange tomatoes in a single layer, cut sides up. Roast on lower rack until tender, 20 to 25 minutes.

    Step 2

    Meanwhile, make sauce: In a small bowl, whisk together mayonnaise, remaining 1/2 teaspoon tarragon, and the lemon juice; season with salt and pepper.

    Step 3

    Lightly oil another rimmed baking sheet. In a food processor, pulse bread with a pinch each of salt and pepper and remaining tablespoon oil until fine crumbs form.

    Step 4

    Pat fish dry with paper towels, and season both sides with salt and pepper. Place fillets on prepared baking sheet. Dividing evenly, spread mustard on top; sprinkle with bread crumbs, gently pressing to adhere. Bake on upper rack until fish is cooked through and coating is browned, 6 to 8 minutes. Serve with roasted tomatoes and sauce alongside.
