  • 1 cup jumbo oats
    Two piles of oats



    Oats are processed by rolling (steamed and pressed) or steel-cutting (cut into pieces). There is…

  • 4 cups milk (or half milk, half water for a less creamy version), plus a dribble more milk to serve



    One of the most widely used ingredients, milk is often referred to as a 'complete' food…

  • ¼ cup dried fruits (optional)

To serve

  • your favourite toppings - brown sugar or honey, sliced bananas, grated apple, blueberries, pinch of cinnamon, natural yogurt, etc



    Honey is made by bees from the nectar they collect from flowers. Viscous and fragrant, it's…


  1. Heat the slow cooker if necessary. Find a sturdy ceramic bowl that will fit in the cooker. Put the oats in the bowl along with a pinch of salt, then pour over the milk, or a mixture of milk and water. Add the dried fruit, if using. Place the bowl in the slow cooker and put on its lowest setting and cook overnight for 7-8 hours. If anyone’s up in the night, give the porridge a quick stir to scrape up the crustier bits from around the edges and bottom, but don’t worry if not.

  2. In the morning, give the porridge a really good stir – it may have developed a crust on top, but just stir this in to break it up. Add a drop more milk to loosen if necessary, then ladle into bowls and add your favourite toppings.

Yum, this porridge came out super smooth and creamy after about 8 hours. I made it with 2/3 water and 1/3 milk. Really good.

Mix your oats, milk, and/or water together, place in bowl or saucepan. Leave in fridge overnight. Or, if desperate to use your slow cooker, put the bowl in your slow cooker. BUT DON'T TURN IT ON! In the morning heat your oats and in 5 mins you've got your lovely, creamy porridge. Leave your slow cooker for ingredients that need long, slow cooking.

All these reviews where people clearly haven't followed the recipe should be removed. The oats ARE NOT to be cooked directly in the slower cooker bowl! You need to put the ingredients into a separate bowl and put that into the slow cooker so it acts like a bain marie. Cooking oats like this improves the digestibility because the enzymes in the oats can get to work on breaking them down at this low temperature. The consistency is also lovely. Just FOLLOW THE RECIPE PROPERLY peeps! P.s. Anyone interested in optimizing the nutrient content of oats should google 'benefits of soaking oats'.

Or maybe amend the recipe to make it clearer?

This was disgustingly vile! Sorry I don’t know what else to say other than that. I had it on warm instead of low as it was cooking quite fast, left it for 7 hours overnight - prepared it and it looked like gloop (similar consistency to PVA glue). Better off doing it in the microwave, takes literally 3 mins!

So, did you use jumbo oats and put your ingredients in a separate bowl, not directly in the slow cooker bowl?

Clearly states in the instructions that the porridge should be put in a sturdy ceramic bowl which is then placed in the slow cooker a bit like a bain marie without the water. It's not supposed to be cooked directly in your slow cooker bowl. I'm guessing this slows down the cooking process even slower which is why it can be cooked a bit longer. Has ANYONE actually tried cooking it according to these instructions or has everyone just done the complete opposite then complained when surprise surprise it didn't work???

I did exactly what recipe says. I was so disappointed with result in the morning. Porridge was turned it’s colour to orange as if burnt and oats lost its shape completely and became like a lumpy glue. There was no texture. I wouldn’t try this recipe again.

I guess the temperatures of different cookers varies but no way should you cook it all night. We make porridge in a slow cooker every day in winter. No more than 2 hours on low setting. If your cooker has a timer use that. We have a cheap plug in timer that we use to set the cooker to come on 2 hours before we get up. Microwaved porridge, even pre soaked, doesn't come close.

Just awful. I'm up often during the night with new baby, after 4 hours (at 3am) the porridge was already so revoltingly overcooked and welded to the sides of the slow cooker pot that I switched it off and abandoned the attempt. So inaccurate the author can't ever have tried this herself.

Can you make this without a slow cooker? It sounds lovely but we don't have one.

Hi there, yes you can, follow the recipe but then cook covered with foil in a low oven for about an hour, thanks.

Alright, so I'll admit ... I haven't tried this yet. But. The recipe does say to put a sturdy ceramic bowl inside your slow cooker ceramic bowl, so this will avoid the sticking to your slow cooker bowl. After some googling, it seems that rolled oats will turn into a sticky mess if you cook for this long. The oats to use seem to be steel cut oats which are also known as Scottish oats. These are chopped rather than flattened, so need cooking for longer and also keep their texture better. I think they might be difficult to find though. The Scottish oats in the supermarket are still rolled if you read the item description :-(

Put a few centimetres of hot water in the main slow cooker bowl. Put the porridge ingredients in a smaller bowl and then put this bowl in the cooker. If your cooker has a 'keep warm' setting just set the porridge to cook for one hour and then it will keep warm all the rest of the night.
