There is something wonderful about opening the oven and finding a pan of glistening salmon, golden potatoes and bright green asparagus all ready at the same moment. The salmon turns tender and flaky, the edges of the potatoes crisp up, and the whole kitchen smells like lemon, garlic and fresh herbs.
This is the dinner I reach for on busy weeknights when I want something that feels special but asks for almost no effort. Everything cooks on a single sheet pan, so there is one dish to wash, and it works just as well for a relaxed Sunday supper or a casual dinner with friends.
SaveI started making this recipe when I was tired of juggling three pots after work. Roasting the potatoes first and adding the salmon later was the trick that finally made everything finish together, and now my family asks for it almost every week.
Sheet Pan Lemon Herb Salmon
Ingredients
Salmon
Vegetables
Lemon Herb Butter
Instructions
- Heat the oven
Place a rack in the center of the oven and heat it to 425°F. Line a large rimmed sheet pan with parchment paper so the potatoes brown nicely and cleanup stays easy.
- Season the potatoes
Add the halved baby potatoes to the pan and toss them with 2 tablespoons of the olive oil, 1/2 teaspoon of the salt and the black pepper for the vegetables. Spread them in a single layer with the cut sides facing down, leaving the center of the pan open.
- Roast the potatoes first
Roast the potatoes for 15 minutes until their cut sides begin to turn golden. Giving them a head start is what lets everything finish at the same time, since potatoes take longer than salmon.
- Make the lemon herb butter
While the potatoes roast, stir together the melted butter, minced garlic, lemon juice, lemon zest, parsley, dill and thyme in a small bowl. The mixture should smell fragrant and look speckled with green herbs.
- Prep the salmon and asparagus
Pat the salmon fillets dry with paper towels and season them with 1/2 teaspoon kosher salt and 1/4 teaspoon black pepper. Toss the trimmed asparagus with the remaining 1 tablespoon olive oil and the remaining 1/4 teaspoon salt on a plate or in a bowl.
- Add the salmon and asparagus
Remove the pan from the oven and push the potatoes toward the edges. Arrange the salmon fillets in the center, skin side down if they have skin, and scatter the asparagus around them in a single layer.
- Spoon on the butter
Spoon about two thirds of the lemon herb butter evenly over the salmon fillets, letting some of it drip onto the vegetables. Top each fillet with 2 lemon slices.
- Roast until flaky
Return the pan to the oven and roast for 12 to 15 minutes, until the salmon flakes easily with a fork and reaches 145°F in the thickest part. The asparagus should be bright green and tender but still slightly crisp, and the potatoes should be golden and soft inside.
- Finish and serve
Drizzle the remaining lemon herb butter over the salmon and vegetables, then let the pan rest for 2 minutes. Serve straight from the pan or move everything to plates, spooning the buttery pan juices over the top.
Substitutions and variations
- Swap the baby potatoes for 1 1/2 pounds of broccoli florets or halved Brussels sprouts, and add them to the pan at the same time as the asparagus since they cook faster.
- Use fresh rosemary or oregano in place of the dill if that is what you have on hand, but chop it finely because it is stronger.
- Replace the butter with extra olive oil for a dairy-free version that is still full of flavor.
- Trout or arctic char fillets work well in place of salmon and cook in about the same time.
Chloe's tips
- Choose fillets of similar thickness so they cook evenly, and let them sit at room temperature for 10 minutes before roasting.
- Cut the potatoes into pieces of the same size so they all turn tender at the same time.
- Pat the salmon very dry before seasoning, because dry fish roasts rather than steams and the butter clings better.
- If your fillets are thin, check them after 10 minutes. If they are thick, they may need a couple of extra minutes.
- Do not crowd the pan. Use two sheet pans if needed so the vegetables roast instead of steam.
How to store it
- Refrigerate leftovers in an airtight container for up to 3 days.
- Reheat gently in a 275°F oven for 10 to 15 minutes, or in the microwave at 50 percent power in short bursts, to keep the salmon from drying out.
- Leftover salmon is delicious cold, flaked over a green salad or stirred into a grain bowl.
- Freezing is not recommended for the full meal because the potatoes and asparagus turn soft, but raw seasoned fillets can be frozen for up to 2 months.
Serving suggestions
This one-pan dinner is complete on its own, but a few simple additions make it even better.
- A squeeze of fresh lemon over the top just before eating
- A crisp green salad with a light vinaigrette
- Warm crusty bread to soak up the garlic butter
- A spoonful of Greek yogurt mixed with dill as a cool sauce
- A glass of chilled sparkling water with lemon or a dry white wine
Frequently asked questions
How do I know when the salmon is done?
The salmon is done when it flakes easily with a fork and turns opaque and light pink in the center. For the most accurate result, use an instant-read thermometer and look for 145°F in the thickest part of the fillet.
Can I use frozen salmon?
Yes. Thaw the fillets overnight in the refrigerator, then pat them very dry with paper towels before seasoning. Cooking salmon straight from frozen on this pan is not ideal because it releases extra water and the vegetables will turn soggy.
Should I cook the salmon with the skin on or off?
Either works. Skin-on salmon helps protect the flesh from drying out, and the skin lifts away easily after roasting. Skinless fillets absorb a little more of the lemon herb butter.
Can I prepare this ahead of time?
You can halve the potatoes, trim the asparagus and mix the lemon herb butter up to a day ahead and store them in the refrigerator. Season and roast just before dinner so the salmon stays moist and tender.
Let's get cooking!
Dinner does not have to be complicated to feel special. With one pan, a handful of fresh ingredients and a little lemony butter, you can put a beautiful, healthy meal on the table tonight, so go ahead and give it a try and enjoy every flaky, golden bite.
