Make sure to carefully follow each step of the instructions for the best results :
Prep the oven and pan:
Preheat the oven to 400°F and line a sheet pan or baking dish with parchment for easier cleanup. Many sheet pan versions of pesto salmon and asparagus start with a hot oven and a single pan so both parts of the meal can roast together.Season the asparagus:
Place the asparagus on one side of the pan and toss it with olive oil, garlic, salt, and black pepper. Roasted asparagus is a common pairing here because it cooks quickly and works well with the fresh flavor of pesto.Prepare the salmon:
Place the salmon fillets on the other side of the pan. Season lightly with salt and pepper, then spoon the pesto over the top of each fillet and spread it evenly. Pesto is usually added directly on top of the salmon before roasting in this style of recipe.Roast until flaky:
Bake for 15 to 18 minutes, or until the salmon flakes easily and the asparagus is tender. Depending on thickness, some recipes suggest checking the salmon a little earlier so it stays moist and doesn’t overcook.Finish and serve:
Remove the pan from the oven and drizzle the salmon with lemon juice just before serving. Serve the salmon and asparagus right away while everything is warm and bright.
