Instructions

  1. Adjust rack to top position (top and middle for 4 servings) and preheat oven to 450°F. Wash and dry produce.
  2. Trim green beans if needed; toss in one oven-ready tray with a drizzle of oil, salt and pepper. (For 4 servings, divide green beans between two trays, using a drizzle of oil in each.)
  3. In a small bowl, combine panko with a drizzle of oil (large drizzle for 4), salt and pepper.
  4. Pat trout dry with paper towels; season with salt and pepper. Drizzle skin sides with oil and rub to coat.
  5. Place trout skin-side down in remaining oven-ready tray. (For 4, divide between two trays.) Spread tops evenly with Dijon mustard; mound with panko mixture, pressing firmly to adhere. Reserve bowl.
  6. Place trays side by side on top rack (ensure oven is preheated); bake until green beans are tender and trout is cooked through, 10-15 minutes. (For 4, bake trout on top rack and green beans on middle rack, swapping halfway.)
  7. Meanwhile, wash and dry bowl used for panko. Combine smoky mustard and mayonnaise in the bowl; stir in water 1 tsp at a time until drizzling consistency.
  8. When trout has 5 minutes left, halve and toast ciabatta. Spread with half the garlic herb butter. Halve each ciabatta half diagonally. (For 4, halve each of the four halves diagonally.)
  9. Once green beans are done, carefully toss with remaining garlic herb butter.
  10. Divide trout, green beans and garlic bread between plates. Drizzle smoky mustard sauce over trout and serve.

Recipe Tips

For extra crispy panko, press the breadcrumb mixture firmly onto the trout.

If you don’t have an oven-ready tray, use a baking sheet lined with parchment paper.

FAQ

Can I use salmon instead of trout?

Yes, salmon works perfectly as a substitute. Adjust cooking time as needed based on thickness.

What can I use instead of smoky mustard?

Regular Dijon mustard mixed with a pinch of smoked paprika can mimic the smoky flavor.

How do I store leftovers?

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