Cooking Steps

Prep & Roast Garlic
1
  • Adjust rack to middle position (middle and top positions for 4 servings) and preheat oven to 450 degrees. Wash and dry produce.

  • Peel garlic. Peel and dice potatoes into ½-inch pieces. Trim green beans if necessary.

  • Place garlic cloves in center of a small piece of foil; drizzle with oil and season with salt and pepper. Cinch into a packet and place on a baking sheet. Roast on middle rack for 10 minutes (you’ll add more to the sheet then).

Cook Potatoes & Make Topping
2
  • Meanwhile, place potatoes in a medium pot with enough salted water to cover by 2 inches. Bring to a boil and cook until tender, 15-20 minutes. Reserve ½ cup potato cooking liquid (¾ cup for 4 servings), then drain. Return potatoes to pot and cover to keep warm.

  • While potatoes cook, in a medium bowl, combine panko, half the Parmesan, 1 TBSP oil (2 TBSP for 4), salt, and pepper.

Bread Trout
3
  • Pat trout* dry with paper towels and season all over with salt and pepper. Place on a plate; drizzle skin sides with oil; rub to coat. Arrange skin sides down on plate.

  • Evenly spread tops of fish with a thin layer of half the mustard. Mound with panko mixture, pressing firmly to adhere.

  • Once garlic has roasted 10 minutes, remove sheet from oven;  carefully add trout to one side (keep garlic packet on sheet).
Roast Fish & Veggies
4
  • Toss green beans on empty side with a drizzle of oil, salt, and pepper. Return to middle rack; roast until veggies are tender and trout is browned and cooked through, 10-12 minutes. (For 4, toss green beans on a second sheet; roast green beans on middle rack and trout and garlic on top rack.)
Make Sauce
5
  • In a small bowl, combine half the vinegar, half the cream sauce, remaining mustard, and 1 tsp sugar (all the vinegar and 2 tsp sugar for 4).

  • Heat a small pan over medium. Add cream sauce mixture. Cook, stirring occasionally, until thickened, 2-4 minutes. Remove from heat; stir in 1 TBSP butter (2 TBSP for 4). Season with salt and pepper. Cover.

Finish Potatoes
6
  • To pot with potatoes, add roasted garlic with its oil, remaining cream sauce base, remaining Parmesan, and 1 TBSP butter (2 TBSP for 4 servings). Mash with a potato masher until smooth and creamy, adding splashes of reserved potato cooking liquid as needed. Season with salt and pepper.

Serve
7
  • Divide trout, green beans, and mashed potatoes between plates. Drizzle trout with creamy mustard sauce and serve. TIP: If sauce has thickened too much, add a splash of water and stir to thin.
