These healthy vegan Overnight Steel Cut Oats Breakfast Jars are versatile and make the perfect grab-n-go meal!
I’ve been eating a lot of oatmeal lately, especially when I’m on the go. I like to switch it up with this Healthy Oatmeal with regular oats, Overnight Steel Cut Oats Oatmeal, or easy small batch Cinnamon Oatmeal.
Sometimes I’ll stop by Starbucks and grab their blueberry oatmeal, which is delicious and always hits the spot. I figured it was time to look into coming up with something that I can make at home and take on the go.
In comes these overnight oats, and not just one serving, but five for the week! I love the idea of having a couple mason jars in the refrigerator ready to grab on the go, or simply take out and eat whenever I’m in the mood.
Cooking the oats for 5 minutes and then letting them sit overnight leaves them a bit softer, chewier and creamier than the no cook version. Top with fresh fruit, nuts, a little maple syrup and plant milk, and you have the perfect steel cut oatmeal breakfast jars!
Ingredients You’ll Need
In this recipe, steel cut oats are simmered with water and spices, then scooped into mason jars and topped with healthy fruits and nuts for a quick and easy breakfast, snack, or to-go meal.
Here is everything you will need:
- Overnight Oats Base: Steel cut oats are the base of this overnight oats recipe and make for a perfect porridge. Full of protein and fiber, this will leave you feeling satisfied and ready to go for a few hours or more.

- Toppings: I love using a variety of toppings for my steel cut oats breakfast jars, it keeps it interesting and versatile. Use any combination of fruits (dried and fresh), and for added protein, nuts, seeds and various nut & seed butters work well.
- Sweetener: Pure maple syrup is my go-to sweetener, but feel free to use organic pure cane sugar, white or brown, to sweeten your overnight oat jars.
- Plant milk: Use your favorite non-dairy milk such as cashew, oat, almond milk, etc., pref. unsweetened.

Rest overnight: Let cool, fill individual mason jars (or other containers), cover and let sit overnight in the fridge. Alternatively, keep it in the pot you cooked it in, cover, and keep in the fridge overnight.
Fill jars: The next day fill your jars with a mix of toppings for grab & go time or simply top each jar when ready to eat.
I prefer to eat my breakfast jars at room temp but you can heat yours either in the microwave for a minute or two, or use a heated pot of water setting the mason jar in the center until warmed.
This will fill 4 – 6 pint sized mason jars with plenty of toppings. Wide mouths are preferred as it’s much easier to spoon out of for eating.
Serves 4 – 6
Store: Keep breakfast jars in the refrigerator for up to 5 days.
I like my porridge on the thicker side, adjust water adding more for a thinner consistency. I prefer to add the non-dairy milk at serving to thin it out a bit.
Adjust the amount of cinnamon and cardamom to suit your taste. I’m in love with cardamom at the moment and find myself using a bit more than suggested here.
