Ingredients
  

  • Salmon: 4 skin-on salmon fillets (5–6 oz each)
  • Asparagus: 1.5–2 pounds asparagus, trimmed
  • Fat for cooking: 3 tablespoons olive oil or avocado oil
  • Butter sauce: 3 tablespoons unsalted butter, melted
  • Lemon: Zest of 1 lemon + juice of 1/2 lemon; extra wedges for serving
  • Garlic: 3 cloves, minced
  • Seasoning: 1 teaspoon sea salt, 1/2 teaspoon black pepper
  • Optional flavor boosters: 1 teaspoon smoked paprika or chili flakes; 1 tablespoon fresh dill or parsley, chopped
  • Garnish (optional): 1 tablespoon capers

Method
 

  1. Preheat and prep: Heat the oven to 425°F (220°C). Line a large sheet pan with parchment for easy cleanup.
  2. Season the asparagus: Toss asparagus with 1.5 tablespoons oil, a big pinch of salt, and pepper. Spread in a single layer on the sheet pan.
  3. Start roasting the veg: Roast asparagus for 6–8 minutes to give it a head start, especially if spears are thick.
  4. Prepare salmon: Pat salmon dry with paper towels. Rub with remaining oil and season both sides with salt and pepper. Place skin-side down on the pan, making space between fillets.
  5. Make the lemon-garlic butter: In a small bowl, mix melted butter, lemon zest, lemon juice, and minced garlic. Stir in paprika or chili flakes if using.
  6. Roast to finish: Spoon half the butter mixture over the salmon. Return pan to the oven and roast 8–12 minutes, depending on fillet thickness. The salmon should flake easily and hit 125–130°F in the thickest part for medium.
  7. Final touch: Drizzle the remaining lemon-garlic butter over the salmon and asparagus. Sprinkle with fresh dill or parsley and capers if you like.
  8. Cool before packing: Let everything rest 5–10 minutes so steam escapes. This helps prevent soggy vegetables in your containers.
  9. Portion: Divide into 4 meal-prep containers, adding lemon wedges on the side.
