How long does it take to grill salmon in foil?

Grilling salmon in foil typically takes about 15 to 20 minutes over medium heat. The exact time can vary based on the thickness of the salmon fillet and the grill's temperature. It's best to check for doneness when the salmon flakes easily with a fork and reaches an internal temperature of 145°F (63°C). Wrapping the salmon in foil helps retain moisture and enhances flavor.
