You’ll be amazed by how good Slow Cooker Jacket Potatoes are. You need only 3 ingredients, some kitchen foil and a slow cooker and you’re set to go. It’s so simple you’ll be cooking your baked potatoes in the slow cooker from now on.

I’ve been using a slow cooker for jacket potatoes for many years, starting when we lived in rural France. Our limited electricity supply meant always being aware of how much power we were using at any one time.

A slow cooker was a perfect low wattage solution for cooking whilst using other appliances. Since then, and not just because it’s economical, the slow cooker has become our favourite way to cook jacket spuds.


Visitors to the Kitchen Shed were always amazed to hear I’d cooked their baked potatoes in a slow cooker. But they were even more surprised when I would serve them Slow Cooker Crispy Roast Potatoes.

What Equipment do I need ?

  • A shallow dish for oil.
  • Baking foil – Squares of aluminium foil large enough in which to wrap each potato helps them to cook evenly.
  • 6.5 litre slow cooker for 6 jacket potatoes or 3.5 litre for 4 potatoes.
  • Kitchen roll – you need a couple of large sheets or 4 small sheets. These will absorb condensation so it doesn’t drip down into the slow cooker pot and ‘dampen’ your potatoes. As an alternative to kitchen roll, a clean tea towel works if it’s been washed using unscented detergent. A heavily fragranced tea towel will taint your slow cooker and its contents.

What Ingredients do I need ?

Baking potatoes, rapeseed oil and salt.
  • Large potatoes – a variety like Maris Piper, King Edward, Wilja or Idaho give the best results. I used Maris Piper but any potatoes labelled as ‘baking potatoes’ are usually reliable too.
  • Rapeseed oil / Canola – you can use olive oil if you prefer.
  • Sea salt – adds flavour to the skin but helps draw the moisture out of the potato for fluffier results.

Recipe FAQs

Is it cheaper to cook jacket potatoes in an oven or a slow cooker ?

Using a slow cooker instead of an electric oven for jacket potatoes will save money on energy bills. Even though the cooking time is longer, a slow cooker still consumes considerably less energy than a traditional electric oven.

How many potatoes can you fit in a slow cooker ?

I use a 6.5 litre slow cooker and I can easily cook 6 large potatoes. A 3.5 litre capacity slow cooker will cook 4 jacket potatoes. Just make sure you have a single layer of potatoes so they cook evenly.

Do they get crispy in the slow cooker ?

Not as such – the skin is not as crispy as oven baked but not as soft as when microwave cooked. They are more like the wrapped in foil jacket potatoes you might buy from a hot potato shop. The absorbent kitchen roll placed between the lid and the slow cooker pot helps deliver a more crispy skin.
We prefer jacket potatoes in the slow cooker because you never get overcooked leathery skins. If you really do miss a crispy skin, try popping them in the oven for 10 minutes at 200 C.

Equipment

  • Baking foil / aluminium foil
  • Slow Cooker I used a 6.5 litre slow cooker
  • Kitchen roll or a clean tea towel

Ingredients

  • 6 large baking potatoes
  • 2 tablespoons rapeseed oil
  • 1 teaspoon sea salt

Instructions

  • Scrub and rinse potatoes to remove any dirt.
  • Prick each potato all over with a fork or skewer.
  • Rub the skins with a small amount of oil and then rub in a little salt.
  • Wrap each potato tightly in baking foil. Place potatoes, foil fold down, in a single layer in the bottom of the slow cooker.
  • Place 2 large sheets of kitchen roll over the top of your slow cooker pot and secure in place with the lid. This helps to prevent water dripping down the inside of the slow cooker pot. If using a tea towel instead of kitchen paper, fold the corners back over the slow cooker lid.
  • Cook for 4 hours on high setting or for 8 hours on low.
  • Pierce a potato with a fork or a skewer to check the potatoes are cooked.
  • Cut your potatoes in half and fluff up with a fork before simply adding butter or your favourite topping.

Notes

  • Make sure you have a single layer of potatoes so they all cook evenly.
  • I used a 6.5 litre slow cooker and it easily accepts 6 large potatoes. A 3.5 litre capacity slow cooker will cook 4 large jacket potatoes. The cooking time will be the same regardless of the number of potatoes cooked.
  • Placing the foil packages fold down on the base of the slow cooker helps to protect your potatoes from overcooking.
  • Alternative to kitchen roll, a clean tea towel works if it’s been washed using unscented detergent. A heavily fragranced tea towel will taint your slow cooker and its contents.

The potatoes turn out perfect inside when made like this. Topped with butter and lots of black pepper is how we love them.
