Step by step
Tap a step to cross it offFoil the Sheet Pan
Tear a sheet of heavy-duty foil 6 inches longer than your salmon side. Lay it centered on a half sheet pan, glossy-side down.
WhyHeavy-duty foil is worth the price — regular foil tears when you fold the pouch and floods your oven with butter.
Place Salmon Skin-Down and Season
Pat a 2 lb skin-on salmon side dry with paper towels and lay it skin-down in the center of the foil. Season with 1 tsp kosher salt, 1/2 tsp black pepper, and 1 tbsp fresh dill.
WhySkin-down means the skin acts as your buffer against the hot pan — the fish above it never touches metal and stays flaky.
Butter, Garlic, and Lemon
Cut 4 tbsp cold butter into 8 pats and distribute across the fish. Scatter 4 sliced garlic cloves and lay 1 thin-sliced lemon (about 8 rounds) across the top in an overlapping single layer.
WhyButter melts into a garlic-lemon sauce inside the pouch — the salmon steams and bastes at the same time. Olive oil works but the sauce is thinner and less rich.
Fold the Pouch
Bring the long sides of the foil together above the salmon and fold down in tight 1-inch folds until snug over the fish. Roll the short ends tightly to seal completely. The pouch should have air space above the salmon.
WhyThe pouch needs headspace for steam to circulate. A tight-to-the-fish wrap steams unevenly and cooks the top before the middle.
Bake to 125°F Internal
20 minBake at 375°F for 18-20 minutes. Open one end of the pouch carefully (steam is hot) and insert an instant-read thermometer at the thickest part — pull at 125°F for medium (buttery, moist).
WhySalmon looks cooked at 140°F but is chalky — 125°F is where the fat still glistens and the flakes fall apart when pressed. Use the thermometer.
Broil-Open for Color and Rest
2 minOpen the pouch fully and fold the foil edges down. Broil on high for 90 seconds to blush the top and set the lemon slices. Rest 3 minutes uncovered, then transfer with a fish spatula to a serving platter.
WhyThe broil is optional but adds a hit of char that makes the fish look like it came off a plancha. Watch it — 3 minutes and it burns.

Frequently Asked Questions
Can I use frozen salmon?
Thaw first — 24 hours in the fridge or 30 minutes in a cold water bath. Cooking from frozen in a foil pouch steams the top before the center thaws.
How do I know when it's done without a thermometer?
Poke the thickest part with a fork and gently twist. Cooked salmon flakes cleanly at that point; raw salmon resists and stays translucent.
How do you reheat leftover oven salmon in foil without ruining the texture?
Salmon is best cold or barely warm. To gently warm, place flakes in a covered dish with 1 tsp water and warm at 275°F for 8 minutes. Never microwave — it turns leftover salmon to a fishy sponge.
What is the target internal temperature for this recipe?
Confirm internal core temperature reaches 125°F using an instant-read digital probe thermometer inserted into the thickest part. Allow the meat to rest for 3 minutes before slicing to let carryover heat equalize and lock in juices.
How do I adapt this meal for picky kids or toddlers?
Portion cooked salmon flakes into a bowl with 1 tbsp mayo per portion and a squeeze of lemon. Salmon salad-style beats a whole fillet on the plate for younger kids.
What are the best side dishes to serve with this?
Recommended sides include Rice pilaf or wild rice, Roasted asparagus or green beans, Cucumber-yogurt sauce.
