Get to the Point
Place 2 lb salmon side skin-down on foil; season with salt, pepper, dill.
Dot with 4 tbsp butter and 4 garlic cloves; layer lemon slices across the top.
Fold foil into a sealed tent, bake 20 min at 375°F to 125°F internal.
Open foil, broil 90 sec to color the top, rest 3 min before serving.
Step-by-Step Guided Instructions
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.
Heavy-duty foil is worth the price — regular foil tears when you fold the pouch and floods your oven with butter.
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.
Skin-down means the skin acts as your buffer against the hot pan — the fish above it never touches metal and stays flaky.
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.
Butter 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.
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.
The pouch needs headspace for steam to circulate. A tight-to-the-fish wrap steams unevenly and cooks the top before the middle.
Bake 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).
Salmon 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.
Open 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.
The 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.
The pouch is a portable delivery system — you can slide the whole thing onto a platter to serve, cut it open at the table, and the smell hits the room at once. Presentation for zero effort.
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.

- Roasted asparagus or green beans
- Cucumber-yogurt sauce
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.
