Ingredients

Vegetables

  • 1 pound baby Yukon Gold potatoes, halved
  • 12 ounces asparagus, trimmed

Protein

  • pounds salmon fillet, skinned and cut into 4 portions

Sauce and Seasoning

  • 2 tablespoons extra-virgin olive oil, divided
  • ¾ teaspoon salt, divided
  • ½ teaspoon ground pepper, divided
  • 2 tablespoons melted butter
  • 1 tablespoon lemon juice
  • 2 cloves garlic, minced
  • 4 tablespoons chopped parsley for garnish

Instructions

  1. Preheat the oven: Preheat your oven to 425°F (220°C) to prepare for baking the salmon and vegetables evenly.
  2. Prepare the potatoes: Toss the halved baby Yukon Gold potatoes with 1 tablespoon of olive oil, half of the salt, and half of the ground pepper. Arrange them on a baking sheet in a single layer.
  3. Start baking potatoes: Place the potatoes in the oven and bake for about 15 minutes to give them a head start on cooking, ensuring they become tender and golden.
  4. Prepare asparagus and salmon: In a bowl, toss the trimmed asparagus with the remaining 1 tablespoon of olive oil, remaining salt, and pepper. In a separate small bowl, mix the melted butter, lemon juice, and minced garlic to create the mustard-garlic sauce.
  5. Arrange the salmon and asparagus: Remove the baking sheet from the oven after 15 minutes. Add the asparagus and salmon portions onto the baking sheet with the potatoes. Brush the salmon generously with the mustard-garlic melted butter mixture.
  6. Bake all together: Return the baking sheet to the oven and bake for an additional 12 to 15 minutes, or until the salmon is cooked through and flakes easily with a fork, and the asparagus is tender but still crisp.
  7. Garnish and serve: Remove from the oven, sprinkle chopped parsley over the salmon and vegetables, and serve immediately for a fresh and vibrant meal.

Notes

  • You can substitute baby Yukon Gold potatoes with fingerling or new potatoes for a similar texture.
  • For an extra tangy flavor, add a teaspoon of Dijon mustard to the butter sauce mixture.
  • If asparagus is not in season, green beans or broccolini make great alternatives.
  • Make sure not to overcook the salmon to keep it moist and flavorful.
