This weekend, my wife and went camping. I tried to impress her with a surprise meal (much more than the usual smokies or hotdogs roasted on a stick). I went for steak, potatoes, mushrooms, salad and a corn on the cob. Everything turned out great --- except for the potatoes.


Potatoes were only cooked after 4 hours in the coals.


Got the fire food and hot (at least 350F, used an infrared thermometer to check). I put the potatoes (Yellow, baking potatoes if it matters) in the hot coals. I have made them like this before, and it typically took 2 hours. And I rotated them periodically (so as to not let the foil burn from prolonged contact). As I mentioned above, I've made potatoes like this before...but never had them take so long to cook.

By the way the rest of the food turned out just fine (actually better than fine, it was the best back country camping meal I had ever made). We ended up using the potatoes for hashbrowns the next morning because we didn't want to wait for them to finish before making/eating the rest of the dishes.


Given the above technique, why did my potatoes not cook like they should.

  • I'd be tempted to use russet. Were they bigger than usual? I've seen people bury the potatoes in coals, that would make it cook evenly and faster. Aug 27, 2019 at 17:38
  • No they were about the same sized as I use normally, and I go with yellow for the size factor (when backcountry camping) having your eyes trick your belly helps a lot with "feeling full" as well as being full.

  • Were the potatoes maybe a bit older? I always find that potatoes which aren't as fresh tend to need longer cooking to those straight out the ground

  • @Bee not that I could see I bought them literally the morning we left, wrapped them in foil at home and walked out the door with them packed in the pocket that I have essentially dedicated to carrying potatoes.

    Hmm, just ad idea! I like that you have a potato pocket though.

Two likely possibilities:

  1. The potatoes had too much foil surface exposed and not enough in contact with hot coals, and as a result were just not getting hot enough. Maybe it was a colder night (were you hiking at altitude?) maybe the coals had a lot of insulating ash, maybe the coals were already too cool (350F is not particularly hot for coals). This is why burying the potatoes in the coals is more common.
  2. The potatoes you bought were defectively dense. Apparently potatoes can have a growing problem where the core of the potato is extra-dense due to weather changes, and that core takes forever to cook through.
  • Yes, I know 350 isn't too hot. I tossed them on at that point and let them go from there. I use the thermometer as a means of getting a baseline (a handy tool from a past job, why not use it right?). It wasn't particularly cold (lows of around 10C, which isn't unusual for our trips) and the altitude was roughly what we normally do. As a result I am more inclined to lean towards Possibility #2.
