Porridge / Overnight Oats Recipes

Assistant Manager and volunteer at Get Loose Foods, Justine, discusses the recipe, cost and nutritional breakdown of her favourite breakfast. The majority of items can be purchased without packaging at Get Loose. She also blogs as Little Green Duckie on a wide range of sustainability issues. This post has been adapted from her site.


Porridge is my go to breakfast all year round. I mix it up with seasonal fruit, have it hot, or cold, depending on the weather and what I am doing.

My basic mix ideas

  • Jumbo oats

  • Dried fruit: sultanas, sour cherries, cranberries

  • Seeds: pumpkin, chia, sesame, linseeds

  • Nuts: walnuts, cashews, pecan

  • Honey

  • Liquid: I use water, dairy milk, or plant milk if I have any.

  • Fruit: in winter I stew cooking apples or rhubarb in a batch (keeps in the fridge in a tub) and add a couple of spoonfuls per day. In summer I chop up seasonal berries. 

  • Nut butter: for a bit of extra decadence I sometimes add a spoonful of nut butter.

For hot porridge 

  • Mix ingredients together (except honey and any fruit), cover with water, or milk, and leave for 30 mins or more. 

  • I normally mix the dry ingredients together the night before so the seed nutrients are more available. But this isn’t essential if you forget!

  • Put in microwave on full power for 1 min, mix, put on again full power for 1 minute.

  • Add a teaspoon of honey. If available, seasonal fresh or stewed fruit.

For cold porridge (also called overnight oats)

  • Mix ingredients together, in an airtight container, with liquid (water or milk), honey and fruit of your choice. 

  • I find the Klean Kanteen steel containers are a good size and leak proof.

  • I do this the night before so I can grab my container straight from the fridge on the way out the door. 

  • If using water, or plant milk, I don’t need to worry about keeping it cold.
