Ingredients
  

  • 4 salmon fillets skin-on
  • 1 lb baby potatoes halved
  • 2 cups broccoli florets
  • 4 tbsp unsalted butter melted
  • Juice and zest of 1 lemon
  • 3 garlic cloves minced
  • 1 tsp Dijon mustard
  • 2 tbsp olive oil
  • Salt and black pepper to taste
  • Fresh parsley or dill optional, for garnish

Instructions
 

  • Preheat oven to 400°F (200°C). Line a large baking sheet with parchment paper or foil for easy cleanup.
  • In a bowl, toss baby potatoes with 1 tablespoon olive oil, a pinch of salt, and pepper. Spread them cut-side down on one side of the sheet. Roast for 15 minutes.
  • While the potatoes roast, make the lemon butter sauce: Combine melted butter, lemon juice and zest, minced garlic, Dijon mustard, salt, and pepper in a small bowl. Mix well.
  • After 15 minutes, remove the tray from the oven. Add the salmon fillets (skin-side down) in the center and broccoli florets to the other side. Drizzle the broccoli with olive oil, salt, and pepper.
  • Spoon or brush the lemon butter sauce over the salmon and drizzle some over the broccoli and potatoes.
  • Return to the oven and roast for 12–15 minutes, until salmon flakes easily and broccoli is slightly crisp.
  • Optional: Broil for 2–3 minutes at the end for extra crispy edges. Watch carefully to avoid burning.
  • Let rest a few minutes. Garnish with chopped fresh parsley or dill and serve with lemon wedges.

Notes

  • Soaking potatoes in cold water for 10 minutes helps make them extra crispy.
  • Fresh lemon juice makes a big difference—skip bottled juice if possible.
  • To store: Refrigerate leftovers up to 3 days. Reheat in a 300°F oven for 10–15 minutes.
