Best Overnight Oatmeal

I've been eating overnight oatmeal since before it even became a ''thing" on the internet. It's been my staple work-day breakfast for at least six years now, and here's why:

  • It is deeeelicious.
  • It keeps me full longer than any other healthy breakfast.
  • It has an awesome texture - I really dislike the mushiness of cooked oatmeal.
  • It is SO easy to make! Less than 5 minutes of prep for several days of breakfast. Works for me!
  • It's so easy to take with me to work, so I don't have to spend time on breakfast at home. Extra sleep!
  • I can eat it cold, warm, or hot, depending on my mood for the day. Cold is actually my favorite, but some days I need a little something warm in the morning.
  • It is heart-healthy.
  • Fiber!! I am a big fan of fiber.
  • There are hundreds of combinations of mix-ins to keep me from getting tired of it.

So you can see why I am a fan. I usually make a big batch of it on Sunday night, and that is my breakfast through Thursday (Fridays I work at home so it is less essential to have breakfast ready to go in the morning). Sometimes I make a batch of oatmeal with all the mix-ins added from the start, sometimes I make a batch of ''plain" oatmeal and mix it up every morning. Either way is super easy!

My ''base" recipe for overnight oatmeal has chia seeds and ground flax seeds for some extra energy, fiber, and healthy fats. I also add a bit of agave so that it has a touch of sweetness. After the oatmeal sits overnight I add some mix-ins for just a bit more sweetness, flavor, and crunch.

Here are my favorite mix-ins for overnight oatmeal:

  1. Brown sugar + cinnamon + raisins
  2. Agave syrup + dried cranberries (craisins) + cinnamon
  3. Unsweetened dried coconut + pineapple chunks + coconut extract (like a piña colada!!)
  4. Freeze dried raspberries + sweetened dried coconut
  5. Sliced bananas + maple syrup
  6. Peanut butter (or lately, PB Fit powder) + cocoa powder
  7. Sliced strawberries + condensed milk
  8. Sweetened cacao nibs (Wild Sweet Nibs) + peanut butter
  9. Sliced almonds + honey

If you are trying to find healthy breakfast options and struggle with time in the morning, this is definitely a recipe worth trying. You might need to experiment with the oatmeal-to-milk ratio at first (depending on your preference), but the recipe below should give you a good start.

Little Cooking Tips

Friday 8th of January 2016

We never had overnight oats before:) It's actually the 1st time we read about it, thank you Kate!:) Sounds like a very interesting way to start the day, and we're very curious as to how this might taste. We like oats and milk, usually with some fresh fruit, like a piece of apple, pear, whatever is in season (figs in late summer is the best addition) and nuts. Your combinations are excellent. We don't have agave syrup, but we do have petimezi (natural grape syrup) which is perfect for this:) Thank you for letting us know about the organic green powder as well, we use one from time to time. Sending you lots of sunshine from Athens! xoxo

Grape syrup! That sounds awesome! I need to find a Greek grocery store around here and try some new things that are not sold in our American stores. Or perhaps I should just take a trip to Greece... one day!

I love the idea of a dish preparing itself in my refrigerator overnight. It's like the cold version of a crockpot! I bet the strawberry and condensed milk add-in is divine. Berries and oatmeal go so well together. And the condensed milk sounds like delicious addition :-)

Ha, I love that analogy. The fridge *is* a cold crockpot! And yea, condensed milk is AWESOME. I don't do that often because I try to stick to healthier things in the morning, but when you happen to have some condensed milk left over in a can... gotta use it somehow! :)

Hmmmm, you may be able to convert me into making overnight oatmeal after all. I've never heard of green powders so I looked up. It's kind of expensive... Can you bring me a little to try on Sunday?


Saturday 9th of January 2016

Of course I can, if you remember to bring the tripod. Deal?
