Jacket Potatoes: or, Baked potatoes when you want to run your oven for a very long time

 It's cold out here, which means that we at A Book of Cookrye are getting excited about baked potatoes! I've seen a lot of people rhapsodize about "jacket potatoes," which I had not heard of. I imagined it to be a cute dish of miniature-sized potatoes served in their skins with herbs all over them. I looked them up and found out that the term is simply Britspeak for baked potatoes. However, people across the Atlantic they seem to get a lot more excited about baked potatoes than we do here. This prompted us to ask: do they bake their potatoes differently over there? 

Turns out, they do!

Jacket Potatoes

Heat oven to 400°.
Cut a cross into the top of each potato. Set directly on the oven rack. Bake for about 1½-2 hours. When the potatoes are baked soft and the skin is crackly, remove from the oven and re-cut the slits on top. Bake 10 minutes more. Serve with whatever you like on your baked potatoes.
If desired, rub the skins with cooking oil and salt before baking to make them even crispier.

For obvious reasons, we would not ordinarily fire up the oven to 400 degrees (that's around 205° for all our Celsius friends) for two hours just for some potatoes. It's an energy extravagance that perhaps makes more sense in the UK, where it's apparently chilly enough that trophy kitchens often display a half-ton cast iron stove that's always turned on and heating up the place. 

However, the temperature outside recently dropped to well below freezing, and it seemed like the perfect time to run the oven to unnecessarily high temperatures for far too long a time. Instead of putting the oven in battle against the air conditioning, we would cozy up the kitchen. Also, in Texas you just never know if you'll still have electricity when it snows, so you have to enjoy it while it lasts.

The instructions are very short, but they are a few sentences longer than my customary method of perforating the spud with a fork and then microwaving it. The baked potato is truly one of the simplest foods in existence. Therefore, people can get hilariously religious about the One True Way to make them. 

If you think people get snobby about the correct preparation of things like with extravagantly long French names and corresponding prices, you need to read the surprisingly angry arguments about the correct way to make cheap and easy foods. For example, people get passionate the right and wrong way to make a grilled cheese. The cheddar vs. processed cheese fights can go on for pages, and that's before we get to the bitter dispute on whether an errant slice of tomato turns it into a melt or if it's still grilled cheese. Where I live, people will say they're above such bickering.... and then launch into sermons about proper barbecue techniques. It's almost as fun to read as the everlasting debate on whether a hot dog is a sandwich. 

Bringing this back to today's venture, people can have very passionate feelings about the correct way to insert a potato in the oven. The "floury vs waxy" dispute can go on longer than it takes to actually bake a potato. Indeed, people can argue about correct versus blasphemous spud-baking methods for longer than it takes to bake a potato in a woodstove, and that includes the time required to build the fire yourself.

We are instructed to first cut a cross on top of the potatoes. A paring knife would of course be perfect for this, but I left mine in my other purse. 

We started keeping it in the silverware drawer because it's surprisingly convenient.

Well, that was quick enough! I guess now we merely put them into the oven. Normally I wouldn't heat up an entire oven for a few spuds, but I've been wanting to try this method ever since I read a lot of improbably enthusiastic prose about them. I don't know anyone who gets that excited about a baked potato around here, so perhaps we are doing it wrong. Also if you realize that you're actually excited about a new (to you) way to bake potatoes, you just embrace the fact that your entertainment doesn't cost much sometimes.

If you look very closely, you can see the cuts.

After a very short time, the cuts began to widen as the spuds shrank.

Ever since we found the baking stone and put pita bread on it, we decided to just leave it there.

Don't the potatoes look lonely in such a big, empty oven? It seems foolish to heat up an entire oven for spuds. Even if you have a smaller oven in the wall, it's a lot of empty space to heat up. Baking your potatoes in a more moderate oven, as we generally do on this side of the Atlantic, allows you to put the rest of dinner in there with them. 

One of the spuds started foaming a little. I do find it strange that the others did not.

We are instructed to remove them from the oven when they're practically done, re-cut them, and return them. Which I did, but I don't know if it made any difference. I thought that maybe the starchy interior of the potato melts back shut under the skin or something, but that didn't happen. Nevertheless, the hot cross spuds were crispy and done.


If you're going to do these for yourself, I suggest you cut them from end to end instead of just in the middle like I did with these. However, if we carefully lift up the flaps and pull these open, we are first struck by how the potato skin nearly isn't crispy and crackly but crunchy. Second, I've heard people wax poetic about fluffy baked potatoes, but this is the first time I've seen one.

You can better see the inner fluffiness when you really split the spud open. 

Apparently it's customary to serve these with a lot of butter and suchlike on top. However, on this side of the Atlantic we have invented the loaded baked potato.

There's meat somewhere under all that cheese.

I would only make these in the winter when the oven heat would improve the house. But with that said, I definitely recommend making these! It's so simple but so, so good. We made them again with a bit of oil and salt rubbed on them before baking, and they were even better.


  1. Looks delicious! I have to admit that I'm a little hesitant about the time and temp - I usually bake my potatoes at 350 for around an hour - but I usually have little Yukon Golds, not the big russet ones. I can't deny that these look delightfully fluffy.

    I hope you're staying safe down there - I'm happy that I've escaped this year's winter storms, after last year's utter misery, but I feel bad for everyone stuck with bad infrastructure and cold weather. (Good infrastructure and cold weather is how we do it up here, and I really prefer it. 😂) (And I feel like I should apologize for constantly talking to you like you're an old friend, but your writing voice is so pleasant that it feels like I've gotten to know you from reading your blog.)

    1. I was a bit hesitant too, but I figured that potatoes were so cheap that it wouldn't be the most ruinous culinary mistake I've ever made.
      We're staying inside until the roads get plowed--- or more realistically, when the ice melts. Like a lot of people who are still a bit shaken from the Great Freeze, we have a generator in the yard if things get dire. I do miss living in a state with good infrastructure. It's so much fun to be like "And we'll get hot chocolate and make peanut brittle and put up snowmen and wear the cozy coats and pick out silly winter scarves and---" when you know that your house will still be warm and lit when you come back.
      And you've nothing to apologize for! It's always nice hearing from you.

  2. Those look like the baked potatoes we served in college. I wasn't involved in baking them, I just put them in a bowl and jammed a spikey hunk of metal in the top to cut the cross shape in them after they were baked.

    1. Your school had a dedicated spud-crosser?

    2. Yes, that is all it got used for now that I think of it. It was really nice to be the person assigned to jamming it into potatoes if you were having a bad day. We also had pie markers for differing numbers of slices that we would use before cutting pies. It was a state university, but I guess our food service was pretty fancy (or at least had fun gadgets).

  3. I like doing a lazy hybrid baked potato. If I'm baking something else, I'll microwave the potato to cook it partway, and then throw it into the oven to finish cooking through and crisp up a little in however long it takes the other thing to cook. It takes advantage of the oven being on anyway, so it doesn't waste energy.

  4. I just ate dinner, but now I'm hungry again. Mmm... melty spuds...
