Instructions

  1. Adjust racks to top and middle positions and preheat oven to 425°F. Wash and dry produce. Cut potatoes into ½-inch pieces. Toss potatoes on a baking sheet with a drizzle of oil, Fry Seasoning, salt and pepper. Roast on top rack until browned and tender, 20-25 minutes.
  2. While potatoes roast, trim and discard bottom 1 inch from asparagus. Zest and quarter lemon. Roughly chop parsley. Place sour cream in a small bowl. Stir in water 1 teaspoon at a time until mixture reaches a drizzling consistency. Season with salt and pepper. Toss asparagus on a second baking sheet with a drizzle of oil, garlic powder, salt and pepper. Roast on middle rack until tender, 10-12 minutes.
  3. Meanwhile, pat trout dry with paper towels. Season all over with salt and pepper. Heat a large drizzle of olive oil in a large nonstick pan over medium-high heat. Add trout, skin side down; cook until skin is crispy, 3-4 minutes. Flip and cook until opaque and cooked through, 1-2 minutes more. Transfer to a plate. Top trout with a drizzle of olive oil and juice from one lemon wedge. Sprinkle with lemon zest and half the parsley.
  4. To a medium bowl, add remaining parsley, 1 tablespoon olive oil and juice from one lemon wedge; whisk to combine. Add potatoes; toss until evenly coated. Taste and season with salt and pepper. Divide potatoes, asparagus and trout between plates. Drizzle everything with sour cream. Serve with remaining lemon wedges on the side.

Recipe Tips

For extra crispy skin, make sure the trout is patted very dry before cooking.

If you don’t have Fry Seasoning, substitute with a mix of paprika, garlic powder, onion powder and a pinch of cayenne.
