Salmon Recipes: One-Pan Lemon Dill Salmon

This one-pan lemon dill salmon dinner pairs tender oven-baked salmon with crisp-edged potatoes and roasted asparagus. Lemon, garlic, and fresh dill keep the flavors bright, while roasting the vegetables and fish on one sheet pan makes a complete meal with straightforward cleanup.

Ingredients

1½ pounds (680 g) baby potatoes, halved or quartered so the pieces are about ½ inch (1.3 cm) thick
2 tablespoons (30 ml) olive oil, for the potatoes
1 teaspoon (5 g) kosher salt, divided
½ teaspoon (1 g) freshly ground black pepper, divided
½ teaspoon (1 g) paprika
1 pound (450 g) asparagus, woody ends trimmed
1 tablespoon (15 ml) olive oil, for the asparagus and salmon
4 skin-on or skinless salmon fillets, about 6 ounces (170 g) each and 1 inch (2.5 cm) thick
2 tablespoons (28 g) unsalted butter
1 tablespoon (15 ml) fresh lemon juice, plus 1 teaspoon (5 ml) finely grated lemon zest
1 small garlic clove (about 3 g), finely minced
1 tablespoon (3 g) finely chopped fresh dill
1 lemon (about 120 g), cut into wedges for serving

Instructions

Heat the oven and prepare the pan. Set a rack in the center of the oven and heat it to 425°F (218°C). Line a large, rimmed sheet pan with parchment paper or foil for easier cleanup. If the pan is crowded, use two pans; vegetables and fish roast more evenly when hot air can circulate around them.
Season and start the potatoes. Pat the potatoes dry, then toss them on the pan with 2 tablespoons (30 ml) olive oil, about ½ teaspoon (2.5 g) salt, ¼ teaspoon (0.5 g) pepper, and the paprika. Arrange them cut-side down in one layer. Roast for 22 minutes, until the edges are beginning to brown and a fork can pierce the pieces with some resistance. Smaller pieces may cook faster, so check them near the end of this first roast.
Prepare the salmon and asparagus while the potatoes roast. Pat the salmon dry, which helps the surface roast instead of steam. Trim the tough ends from the asparagus and cut thicker spears in half if needed to make them cook at roughly the same rate as thinner ones. Toss the asparagus with the remaining 1 tablespoon (15 ml) oil and a pinch of the remaining salt and pepper. Season the salmon on both sides with the rest of the salt and pepper.
Add the fish and asparagus. Take the hot pan out of the oven and turn the potatoes with a spatula. Make space for the salmon fillets and arrange the asparagus in the remaining open areas. If the pan is too full, move the potatoes to a second pan rather than stacking the ingredients. Return the pan to the oven and roast for 10 to 14 minutes. The asparagus should be tender with lightly browned tips. Check the salmon in its thickest part with a food thermometer; USDA FSIS recommends a safe minimum internal temperature of 145°F (63°C) for fish. Thicker fillets can need the full cooking time, while thinner pieces may be ready sooner.
Make the lemon-dill butter. While the pan finishes cooking, melt the butter in a small microwave-safe bowl in short bursts or in a small saucepan over low heat. Stir in the lemon juice, lemon zest, minced garlic, and chopped dill. Taste and add a little more lemon juice or salt if you like. Keep the mixture warm, but do not let it brown.
Finish and serve. Once the salmon reaches 145°F (63°C), remove the pan from the oven. Spoon the lemon-dill butter over the salmon and drizzle a little over the asparagus and potatoes. Serve with lemon wedges. The fish can be rested for a few minutes while you set the table, but it does not need a long rest; a lengthy wait can cool the vegetables.

Tips

Choose evenly sized fillets. Salmon portions that are close to the same thickness finish at about the same time. If one fillet is noticeably thinner, check it early and take it off the pan as soon as it reaches 145°F (63°C), leaving thicker pieces to continue cooking. A thermometer is more dependable than judging doneness by color alone.
Cut the potatoes small and evenly. Pieces around ½ inch (1.3 cm) thick roast in the time allowed here. Larger chunks take longer and can still be firm when the fish is ready. If your potatoes are larger, give them an extra 5 to 10 minutes before adding the salmon and asparagus.
Keep the sheet pan uncrowded. A crowded pan traps steam and makes potatoes softer rather than browned. Use two pans if necessary, and rotate their positions in the oven halfway through the final roast if your oven browns unevenly.
Swap ingredients thoughtfully. Dried dill works if fresh is unavailable; use 1 teaspoon (1 g) in place of 1 tablespoon fresh, since dried herbs are more concentrated. Green beans can stand in for asparagus, though thick beans may need a few extra minutes. If using salted butter, reduce the added salt and taste the sauce before serving.

Serving Suggestions

This recipe already includes a starch and a green vegetable, so it can go straight from the pan to the table as a complete dinner. For a more substantial spread, add a crisp green salad dressed with a simple vinaigrette, or serve warm crusty bread to catch the lemon butter. A spoonful of plain yogurt mixed with lemon and dill is another cool accompaniment, particularly if you prefer a little extra sauce.

For serving, transfer the potatoes and asparagus first, then place a salmon fillet beside each portion. Spoon the buttery pan juices over the fish rather than pouring them all over the vegetables; that keeps the potatoes from losing their browned edges. Offer extra lemon wedges so each person can adjust the acidity. If serving guests, keep the fish on a warm platter and bring it to the table soon after cooking, when its texture is at its best.

Variations

Use another herb. Parsley gives a clean, mild finish, while chives add a gentle onion note. Replace the dill with the same amount of chopped parsley or chives. A little chopped tarragon also works, but its anise-like flavor is more pronounced, so begin with 1 teaspoon (1 g) and add more only if desired.

Try a mustard-lemon finish. Whisk 1 teaspoon (5 g) Dijon mustard into the melted butter with the lemon and garlic. It makes the sauce tangier and slightly more savory without changing the roasting method. For a dairy-free version, use 2 tablespoons (30 ml) olive oil instead of butter; the result will be lighter and less creamy.

Change the vegetables. Broccoli florets, sliced zucchini, or halved cherry tomatoes can replace the asparagus. Broccoli may need to go on the pan at the same time as the salmon if cut small; zucchini and tomatoes cook quickly, so add them during the final 8 to 10 minutes. Avoid assuming every vegetable needs the same time—check tenderness and remove any that finish before the salmon.

Add a gentle chili kick. Stir a pinch of red pepper flakes into the lemon butter, or season the salmon with a small pinch of cayenne along with the paprika. Keep the amount modest so it complements, rather than covers, the fresh lemon and dill.

Storage and Reheating

Refrigerate leftover salmon and vegetables within 2 hours of cooking, packed in a shallow airtight container. They keep for 3 to 4 days in the refrigerator. For the best texture, store the salmon separately from the potatoes and asparagus if convenient, and keep any extra lemon butter in a small covered container. The fish may firm up after chilling, while the vegetables will soften somewhat; that is normal.

For safe reheating, warm leftovers until they reach 165°F (74°C), checking the thickest piece with a food thermometer. In a microwave, cover the salmon loosely and heat in short 30-second bursts, checking between bursts so it does not overcook; add a teaspoon of water or butter to help keep it moist. You can also reheat the vegetables separately on a baking sheet in a 350°F (177°C) oven until hot, then add the salmon for the final few minutes. Freezing is possible for up to 2 months for best quality, though thawed salmon and asparagus will be softer. Thaw overnight in the refrigerator, then reheat to 165°F (74°C).

Frequently Asked Questions

Can I use frozen salmon?
Yes. Thaw it completely in the refrigerator before cooking, then pat it dry so excess surface moisture does not interfere with roasting. If the fillets are still partly frozen, they will cook unevenly and the vegetables may be ready before the centers of the fish. Once thawed, follow the same temperature check and cook to 145°F (63°C).

Should I leave the skin on the salmon?
Either skin-on or skinless fillets work. Skin-on fillets can be placed skin-side down, and the skin helps hold the fish together as it cooks; it may not become crisp on this vegetable-filled sheet pan. If you do not plan to eat the skin, it is easy to lift the cooked salmon away from it when serving.

How can I tell when salmon is done without cutting it open?
A food thermometer is the clearest check: insert it sideways into the thickest part of the fillet and look for 145°F (63°C). Salmon may also look opaque and separate into flakes when gently pressed, but appearance varies with the fish and is less reliable than temperature. Begin checking the thinner fillets at the 10-minute mark.

Can I prepare parts of the recipe ahead?
Yes. Trim the asparagus, cut the potatoes, and mix the salt, pepper, and paprika several hours ahead; refrigerate the prepared vegetables in covered containers. You can also make the lemon-dill butter earlier in the day and chill it, then gently melt it before serving. For the best result, season the salmon shortly before it goes into the oven rather than leaving it salted for a long period.

Can I make this without asparagus?
Yes. Use another quick-cooking vegetable, such as green beans or small broccoli florets, or roast the potatoes and salmon on their own and serve a separate salad. If you choose a vegetable that needs longer than about 10 to 14 minutes, start it with the potatoes or roast it on another pan so the salmon is not left in the oven too long.
