How To Make the Best Garlic Butter Salmon in Foil

A side of salmon cooked in a foil packet with garlic butter is the easiest way to serve salmon for a crowd. Cook this one on the grill or in the oven.

2 cups cold water
1 tablespoon kosher salt
1 (2-pound) side salmon, pin bones and scales removed
6 cloves garlic, minced
4 medium scallions, thinly sliced
2 tablespoons freshly squeezed lemon juice (from 1 lemon), plus 1 medium lemon, thinly sliced
4 tablespoons (1/2 stick) unsalted butter, thinly sliced
Measuring cups and spoons
Aluminum foil
Baking sheet
Small bowl
13x9-inch baking dish
Paper towels

Soak the salmon in salt water for 1 hour. Place the water and salt in 13x9-inch baking dish and stir to dissolve the salt. Place the salmon skin-side up in the brine. Cover and refrigerate for 1 hour. (This step will reduce the white film that comes from baking salmon in a packet.)
Season the salmon. Prepare a large piece of aluminum foil (about 18x18 inches). Remove the salmon from the brine and pat dry with paper towels. Place skin-side down on the foil. Sprinkle evenly with the garlic and scallions. Drizzle the lemon juice over the salmon.
