Crispy Rainbow Trout with Lemon-Parsley and Roasted Vegetables

Dinner5 min2271 cal / serving

This elegant yet simple dish brings together crispy-skinned rainbow trout, bright lemon and parsley and perfectly roasted potatoes and asparagus. A silky sour cream sauce ties everything together, creating a meal that feels special enough for company but easy enough for a weeknight.

The trout is pan-seared until the skin is golden and crunchy, then finished with a squeeze of lemon and a shower of fresh zest and parsley. Roasted red potatoes and tender asparagus round out the plate, all drizzled with a tangy sour cream sauce that adds a creamy finish.

Instructions

  1. Preheat oven to 425°F with racks in top and middle positions. 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 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. 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. Drizzle with olive oil and juice from one lemon wedge; sprinkle with lemon zest and half the parsley.
  4. In a medium bowl, combine remaining parsley, 1 tablespoon olive oil and juice from one lemon wedge; whisk. Add potatoes; toss to coat. Season with salt and pepper. Divide potatoes, asparagus and trout between plates. Drizzle everything with sour cream. Serve with remaining lemon wedges.

Recipe Tips

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

If you don’t have Fry Seasoning, substitute with a blend of paprika, garlic powder, onion powder and salt.

Adjust roasting time for asparagus depending on thickness; thinner spears may cook faster.

FAQ

Can I use a different type of fish?

Yes, you can substitute rainbow trout with other firm white fish like cod or halibut. Adjust cooking time as needed.

Can I make this recipe dairy-free?

Yes, use a dairy-free sour cream alternative or omit the sauce. The dish is still flavorful without it.

How do I store leftovers?

Store leftovers in an airtight container in the refrigerator for up to 2 days. Reheat gently in a skillet or oven to maintain crispiness.
