Garlic and butter might be one of the greatest flavor pairings of all time. We’ve added the dynamic duo to bread, potatoes, pasta, meatballs, mushrooms, biscuits—and more. Now, garlic butter is here to save your weeknight dinner with this one-pan salmon & asparagus meal that's ready in as little as 30 minutes!
In this simple sheet-pan supper, salmon teams up with asparagus and onions. Giving the veggies a head start before adding the salmon makes sure that everything is cooked to perfection. The asparagus will be crisp-tender, the red onion wedges will melt down and get a little sweet, and the salmon will be a little browned on the edges, but still tender in the middle.
The garlic butter goes on during the second half of cooking to make sure it doesn’t burn, but this isn’t just straight garlic butter. This amped-up version has a little lemon zest and juice to help cut through the richness and chopped parsley for color and freshness. Spooning the delicious butter over the fish and veggies pulls everything together—and it all comes together in 30 minutes! Talk about a weeknight winner.

Ingredients
- 1
(1-lb.) bunch asparagus, trimmed
- 1
medium red onion, halved, sliced lengthwise into 1/2"-thick wedges
- 2 Tbsp.
extra-virgin olive oil
Kosher salt
- 4
(6-oz.) salmon fillets, skin-on if desired
Freshly ground black pepper
- 1/2 cup
(1 stick) unsalted butter, melted
- 4
large cloves garlic, finely chopped
- 2 Tbsp.
chopped fresh parsley leaves, plus more for serving
- 3
medium lemons, 1 zested and juiced, 1 juiced, 1 cut into wedges
Directions
- Step 1Place a rack in top third of oven; preheat to 400°. Arrange asparagus on one side of a large rimmed baking sheet and onion wedges on the other. Drizzle vegetables with oil; season with salt and toss to coat. Spread vegetables in an even layer, keeping each on their own side of baking sheet. Roast until just softened, about 10 minutes.
- Step 2Meanwhile, season salmon with 1 teaspoon salt and 1/4 teaspoon pepper. In a small bowl, mix butter, garlic, parsley, lemon zest, and 3 tablespoons lemon juice; season with salt and pepper.
- Step 3Remove baking sheet from oven; push onion to one side and asparagus to the other. Arrange salmon skin side down in center of baking sheet. Spoon about three-quarters of butter mixture over salmon. Spoon remaining butter over vegetables.
- Step 4Bake salmon 8 minutes. Turn on broiler and broil on high, watching closely, until salmon is just cooked through and vegetables are tender and browned in spots, 3 to 5 minutes more.
- Step 5Top with parsley. Serve with lemon wedges alongside.
