# How To Make It:

01 - Preheat the oven to 400°F.
02 - Arrange the leeks and red onion in a single layer on a large baking sheet. Drizzle with olive oil, sprinkle with salt and pepper, and toss to coat evenly.
03 - Roast the vegetables for 10 minutes until they begin to soften.
04 - Remove the baking sheet from the oven. Nestle the salmon fillets skin-side down among the vegetables. Arrange lemon slices over the salmon.
05 - Return to the oven and roast for 12–15 minutes, or until the salmon is just cooked through and vegetables are tender.
06 - While the salmon bakes, prepare the parsley dressing: In a small bowl, combine parsley, garlic, Dijon mustard, capers, lemon zest, olive oil, and lemon juice. Stir well. Season with salt and pepper to taste.
07 - Transfer the roasted salmon and vegetables to plates. Spoon the parsley dressing generously over the salmon. Serve immediately.

# Expert Suggestions:

01 -
  • Everything happens on one sheet pan which means almost zero cleanup and more time for actually eating
  • The leeks become sweet and buttery while the salmon stays perfectly tender a combination that just works every single time
02 -
  • Dry your salmon fillets with paper towels before roasting this helps the skin crisp instead of steaming
  • The vegetables will shrink significantly as they roast so do not worry if the baking sheet looks crowded at first
03 -
  • Buy salmon fillets that are roughly the same thickness so they finish cooking at the same time
  • Make extra dressing and keep it in the fridge it is fantastic on salads eggs or grain bowls
