How to Cook the Perfect Jacket Potato in a Microwave

How to Microwave a Potato

As this is a good art blog, you might be surprised to know that I do some of my cooking in my microwave (not all – promise!) I’m certainly not one of those people who thinks that a microwave is “cheating” – none of us always have time to cook a gourmet meal!

That that said, there’s a right and wrong way to cook foods in the microwave. And this is especially true with potatoes. While a baked potato can make the perfect snacky-meal, especially topped with chili or vegetables, no-one wants a hard, underdone potato on their plate.

In short, if you want your dinner quickly but want it to be tasty too, then a microwaved potato could be the perfect solution – but you need to do it the right way.

In this post, I’ll go through my simple process for cooking a jacket potato in the microwave. You might need to adjust the timings slightly depending on the size of the potato, but this method should be a good place to start.

How to Cook the Perfect Jacket in a Microwave

  1. The first step is choosing the right potato. Any size can be baked, but add an extra minute on for larger ones. Russet potatoes can do the job, but if you’re cooking more than one try to get them at around the same size.
  2. Now scrub the spuds all over to remove any dirt that might be left on the skin. I use a clean sponge for this, but some kitchen roll can do the job.
  3. Next, use a fork to poke holes in the potato skin. I do this at least four times on each side of all the potatoes. If you forget this, don’t be surprised if trapped steam causes your potato to escape!
  4. Microwave on full power for around four minutes. Then take the potato out, turn it over and cook for another four minutes. This is for a single potato: if you’re cooking more than one, add an extra four minutes for each additional spud.
  5. OPTIONAL: If you have a grill microwave, you can use the grill throughout the cooking to get a crisper skin. Be careful the skin doesn’t burn though. If you like the sound of a grill microwave, I bought mine after reading the excellent reviews on
  6. Remove the potato and use a knife to check it’s cooked all the way through. If it is, slice it down the middle and finish with chilli, beans or any other topping.
  7. Enjoy!

As you can see, this method is as simple as they come, but should give you consistently good potatoes. There’s also the option of finishing the potato off in the oven to give it a crispier skin, but if you’re in a rush the microwave-only method works well.

My personal favourite is baked potato with butter and chili for lunch. It only takes 10 minutes to make and is much nicer than a simple sandwich. You can even make it at work if you have access to a microwave.

If you try this method, I’d love to hear how it goes in the comments! If you have any tips or tricks for cooking a potato in the microwave it would be great to hear them too.
