Sheet-Pan Garlic Butter Salmon & Asparagus
Equipment
- Rimmed baking sheet/sheet pan
- Parchment paper or aluminum foil (optional, for easier cleanup)
- Small microwave-safe bowl
- Measuring spoons
- Zester or microplane (for lemon zest)
- Knife and cutting board
Ingredients
- 4 salmon fillets about 6 oz each, skin-on or skinless
- 1 pound fresh asparagus woody ends trimmed
- 4 tablespoons unsalted butter
- 4 cloves garlic minced
- 2 tablespoons fresh lemon juice
- 1 teaspoon lemon zest
- 2 tablespoons fresh parsley chopped, divided
- 1 tablespoon olive oil
- 1/2 teaspoon red pepper flakes optional, for heat
- Salt and freshly ground black pepper to taste
- Lemon wedges for serving
Instructions
- Preheat and prep. Set your oven to 400°F (200°C) and line a rimmed baking sheet with parchment paper or foil if you want to make cleanup even easier. Pat the salmon fillets dry with paper towels – this helps them get a nice finish rather than steaming.
- Make the magic butter. In a small microwave-safe bowl, combine butter, minced garlic, lemon juice, lemon zest, half the chopped parsley, and red pepper flakes (if using). Microwave in 20-second intervals until butter is just melted. Stir to combine. Try not to drink this mixture – I know it's tempting.
- Prepare the asparagus. Place the trimmed asparagus on the sheet pan and drizzle with olive oil. Season with salt and pepper and toss to coat. Arrange in a single layer, then push them to create spaces for the salmon fillets.
- Add the salmon. Place the salmon fillets among the asparagus, skin-side down if your fillets have skin. Season generously with salt and pepper.
- Butter everything up. Pour about two-thirds of the garlic butter mixture over the salmon fillets, reserving the rest. Use a spoon to ensure each fillet gets a good coating of buttery goodness.
- Roast to perfection. Pop the sheet pan in the preheated oven and roast for 10-15 minutes, depending on the thickness of your salmon. For medium doneness, look for an internal temperature of 125-130°F (52-54°C). The salmon should flake easily with a fork but still have a slightly translucent center.
- Finish with more butter. Once out of the oven, drizzle the remaining garlic butter over both the salmon and asparagus. Sprinkle with the remaining fresh parsley.
- Serve immediately with lemon wedges on the side for an extra citrus kick. Marvel at how something this delicious came together so quickly.
Notes
- For perfect asparagus: Choose spears of similar thickness so they cook evenly. Very thick spears might need an extra minute or two of cooking time.
- If you’re not a fan of asparagus, green beans or broccoli make excellent substitutes and cook in about the same time.
- The best salmon: Look for center-cut fillets of even thickness for the most consistent cooking. Wild-caught salmon tends to be leaner than farmed, so it may cook slightly faster.
- For a crispier top on your salmon, you can broil it for the final 1-2 minutes of cooking time – just watch carefully to prevent burning!
Common Mistakes to Avoid
- Overcooking the salmon. This is the cardinal sin of salmon preparation! Overcooked salmon is dry and loses its buttery texture. Remember that salmon will continue cooking for a minute or two after you remove it from the oven, so it’s better to err on the side of slightly underdone.
- Not drying the salmon before cooking. Excess moisture will cause the salmon to steam rather than roast. Take a moment to pat those fillets dry with paper towels.
- Crowding the sheet pan. Give your ingredients some space! Overcrowding leads to steaming instead of roasting, which means less flavor development and potentially soggy asparagus.
- Using cold salmon straight from the fridge. Let your salmon sit at room temperature for 15-20 minutes before cooking for more even results. Cold salmon can cook unevenly, with overcooked outsides and undercooked centers.
Variations & Customizations
- Herb Lover’s Version: Add 1 teaspoon each of fresh thyme and dill to the garlic butter mixture for an herby flavor explosion.
- Honey Garlic Twist: Add 1 tablespoon of honey to the garlic butter for a sweet and savory glaze that caramelizes beautifully.
- Mediterranean Style: Top the salmon with thin slices of lemon and a few capers before roasting, then sprinkle with crumbled feta cheese after cooking.
FAQs
Can I use frozen salmon for this recipe?
Yes, but with a few adjustments! First, make sure to thaw your salmon completely in the refrigerator overnight. Then, it’s extra important to pat it very dry before cooking, as frozen salmon tends to release more moisture. You might also need to add 2-3 minutes to the cooking time. One advantage of previously frozen salmon is that it’s often more consistently cut than fresh fillets, which helps with even cooking. Just make sure you’re buying good quality frozen salmon – look for individually vacuum-sealed fillets for the best results.
What’s the best way to tell when salmon is done cooking?
The most reliable method is using an instant-read thermometer inserted into the thickest part of the fillet. For medium doneness (which most people prefer), you’re looking for 125-130°F (52-54°C). If you don’t have a thermometer, gently press the top of the salmon with a fork or your finger – it should be firm but still have some give, and the fish should flake easily while maintaining a slightly translucent center. Remember that carryover cooking will continue after you remove it from the oven, so it’s better to pull it out a minute early than a minute late!
Can I make this recipe ahead of time for meal prep?
While this dish is best enjoyed fresh from the oven, you can certainly prep components ahead of time! Trim the asparagus, mix the garlic butter (but don’t melt it), and have your salmon portioned and ready to go. When you’re ready to cook, it will take just minutes to assemble. If you do want to make the entire dish ahead for meal prep, slightly undercook both the salmon and asparagus, then refrigerate in separate containers. Reheat the asparagus in a hot skillet or in the oven until warm, but enjoy the salmon cold or at room temperature to avoid overcooking it. Cold leftover salmon is actually delicious flaked over a salad or made into a quick salmon salad with a bit of mayo and herbs!
