OVERNIGHT STEEL-CUT OATS OATMEAL
Overnight Steel Cut Oats Oatmeal made in a slow cooker with banana, cinnamon, vanilla, and naturally sweetened with pure maple syrup is a warm and cozy way to start the day! 100% whole food plant based recipe.
- Cook Time: 3 - 8 hours
- Total Time: 57 minute
- Yield: Serves 4 - 6 1x
- Category: Breakfast
- Cuisine: Vegan
- 1 ½ cups steel-cut oats
- 3 cups water
- 3 cups unsweetened almond milk (or your favorite plant milk)
- 1 – 2 ripe bananas (about ¾ – 1 cup), mashed
- ¼ cup pure maple syrup
- 1 ½ teaspoons cinnamon
- 1 teaspoon vanilla extract or vanilla powder
- pinch of mineral salt
- chopped walnuts, almonds or pecans
- banana slices or fresh berries
- goji berries or toasted coconut
Grease bowl: Lightly grease the sides of the insert with oil. This will keep the mixture from sticking to the sides, but can be optional.
Slow cooker: In a 4 – 6 quart crock pot, place oats, water, milk, mashed banana, maple syrup, cinnamon, vanilla and pinch of salt, stir to mix, cover and cook on low for 3 – 5 hours, or up to 8 hours for overnight. If you can, it does help to stir 2 -3 times during cooking, but is not necessary.
Cool down: Once done, give a good stir, and let cool a bit. Oats will thicken upon standing. Add a tad extra non-dairy milk or water as needed to create desired consistency. Adding more liquid will create a creamier consistency.
Serve: Spoon into individual serving bowls and top with any of the optional toppings of choice. Drizzle a little non-dairy milk over top if you like.
Serves 4 – 6
Store: Leftovers can be stored in an airtight container in the refrigerator for 5 – days. Can be reheated with a little milk or water on the stove top over low, or in the microwave for a minute or two.
Make this virtually fat-free by omitting nuts.
Bananas can be mashed smooth or left a little chunky. Also, try subbing the banana with pumpkin puree.
I do not recommend substituting old-fashioned or quick cooking oats in place of the steel-cut oats as regular oats require less liquids.
