Overnight Oats in a Jar

Print Friendly

I am a fan of all things oats.  Loaded with protein and fiber, but relatively low in calories.  The high amount of fiber keeps you with a full feeling for a long time afterward.  Something that boxed cereal could never do.  I often have homemade granola for breakfast.  This is so easy, I wonder why I didn’t try it sooner!

I initially saw a recipe on Food Babe’s blog called, The Perfect Parfait.  Her recipe inspired me to try it.  So good!  I love how this recipe is very adaptable.  You can really add whatever you like and change it up daily so you never get bored. I used a recycled pickle jar to hold my oats, but a mason jar would work well too. This is great for those mornings that you really have to rush.

Overnight Oats in a Jar



  • Rinse your groats beforehand. Throw everything in the jar the night before.  If you like things a little sweet, you could throw in some chopped dates or raisins. 
  • Store in the fridge overnight.  Just pull out and eat in the morning.  Easy as that. This will be a breakfast I will have at least twice a week. I love it and I hope you will too.

  1. I am curious if it makes a difference if I make this in a plastic container instead of glass jar? I know a lot of people don’t use plastics, but I don’t have any glass jars right now and want to try this. Thanks!

  2. Is this dish supposed to be super chewy? I made it last night for this morning and was just surprised at how chewy it was. Thanks!

    1. The groats do have a little crunch to them. If you want them softer, you can soak them overnight, or just use rolled oats next time.

  3. Do you buy the vanilla beans already ground, if so where? Or do you ground them yourself, any instructions would be helpful as this is new for me? Thanks!

  4. I have been making these for over a year now. I find you can freeze them, but i would keep them in there for over a month. Also i have added yogurt in with mine (whatever you prefer) for some extra flavor. And reduce the amont of liqiuds. Also frozen friuts can work great if you have them on hand. I find that the chia seeds are something not to be leftout! Thanx so much for all your different variations, going to try a few out today!

  5. Hi, I love oats and eat porridge made from rolled oats or steel-cut oats nearly daily, made with similar ingredients as your various overnight oat recipes, but I cook mine. I have done overnight oats only once ever, and I did them with rolled oats. I can see that steel-cut oats would be fine as well. But are you sure that whole oats (groats) are OK to be made like this? If you want to cook them, they require 45-60 minutes of cooking on a stove, unlike about 20 minutes for steel-cut. So I am just wondering if the groats would soften enough overnight to become edible, as they are like sealed dense little packages, unlike the steel-cut ones which essentially have ‘windows’ for the liquid to go in.

    Also, have you tried other grains this way? Would wheat and its relatives (kamut, spelt, rye) work if made in this way? I am thinking not, as those grains are harder than oats, and also have gluten which I am sure needs cooking. Otherwise I think wheat and its relatives done overnight would upset the stomach. So which other grains might work with the overnight method? Perhaps barley? Thanks!

    1. The oat groats have a crunch still in the morning. If you want them softer, soak them in water overnight prior to making the overnight oats.

  6. Do you have to use GF oats? I wasn’t sure if this was a lifestyle/health choice or if non-GF would affect the outcome. Thanks!

    1. If you don’t have a problem with regular oats, you can use them. In order to call the recipe gluten free, I need to state gluten free oats. Oats don’t contain gluten, but they are often processed in plants that also process wheat. If you don’t have a problem with gluten, just use regular rolled oats.
