Tyson Steele survived 23 days in subzero temperatures living in a makeshift shelter and rationing cans of beans and jars of peanut butter he salvaged from the fire.
The 30-year-old was picked up by Alaska State Troopers on Thursday at his remote home 20 miles outside of Skwentna - a village with a population of just 35.
A fire in mid-December burned Mr Steele's remote cabin to the ground leaving him with no means of communication. His dog, six-year-old Labrador Phil, was killed in the blaze.
The Utah-native told troopers a large piece of cardboard in his wood stove had led to the fire.
“It started with a pretty hasty mistake," he said.
"My wood stove is very, very old. The mistake I made – sorry, my thoughts are still a little scattered – the mistake I made, I got hasty and I put a big piece of cardboard in the stove to start the fire."
He added: "I grabbed everything that was on my bed. You know, blankets on my bed. I just grabbed some coats, some sleeping bags – whatever – just a bag of something and whatever and wrapped it up in the blanket and I rush outside".
Only after leaving the cabin did Mr Steele notice his dog was still inside.
Mr Steele slept in a snow cave for two nights before creating a tent-like shelter out of tarpaulin and some off cuts.
Family members and friends requested a welfare check be carried out after not hearing from him for several weeks.
The trooper helicopter crew reached the home at around 11am on Thursday - 23 days after the cabin burned down.
Alaskan State Trooper Ken Marsh said the survival was "stunning".
