Instructions

  1. Preheat oven to 425°F with racks in top and middle positions. Wash and dry produce. Cut red potatoes into ½-inch pieces. On a baking sheet, toss potatoes 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 the lemon. Roughly chop parsley. In a small bowl, combine sour cream with water 1 teaspoon at a time until drizzling consistency. Season with salt and pepper. On a second baking sheet, toss asparagus with a drizzle of oil, garlic powder, salt and pepper. Roast on middle rack until tender, 10-12 minutes.
  3. Pat trout dry with paper towels and 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. Drizzle with olive oil and juice from one lemon wedge. Sprinkle with lemon zest and half the parsley.
  4. In a medium bowl, whisk together remaining parsley, 1 tablespoon olive oil and juice from one lemon wedge. Add roasted potatoes and toss to coat. Season with salt and pepper. Divide potatoes, asparagus and trout between plates. Drizzle everything with sour cream sauce. Serve with remaining lemon wedges on the side.

Recipe Tips

For extra crispy skin, make sure the trout is patted very dry before cooking and don’t move it until it’s ready to flip.

If your asparagus spears are thick, consider halving them lengthwise for even roasting.

The sour cream sauce can be thinned with a little more water if it becomes too thick.

FAQ

Can I substitute another fish for rainbow trout?

Yes, you can use other mild white fish fillets like tilapia or cod. Adjust cooking time as needed based on thickness.

What can I use instead of fry seasoning?

You can substitute with a blend of paprika, garlic powder, onion powder, salt and pepper.

Can I prepare the vegetables ahead of time?

Yes, you can cut the potatoes and trim the asparagus in advance. Store them separately in the refrigerator until ready to roast.
