Coat your slow cooker with cooking spray, butter or coconut oil. Add all the ingredients into slow cooker and mix well.

Cook on low for 6-8 hours. If you have a programmable slow cooker, set it to cook on low for 7 hours and then switch to warm.

In the morning, give the oats a good stir as the oats will settle to the bottom. Portion into a bowl to serve and top with pecans, maple syrup and almond milk.

Let the oatmeal cool and place into a sealed container in the fridge for up to a week. You can reheat the oatmeal on the stovetop or microwave. Just add a little additional milk to loosen the oatmeal, if needed.
