Jammy Blueberry Oats

These Jammy Blueberry Oats have been a staple on my Instagram stories for months, and I FINALLY got around to putting up the recipe! Every time I share these oats, my DMs are flooded with questions on how to make them. And it’s really just one simple science trick that will make these the easiest (and most delicious) oats you’ve ever made.

Overnight oats can step aside, because this warm bowl of deliciousness only takes about 10 minutes to make, and it will leave you full for hours. Plus the best part is it uses minimal ingredients and you can put whatever you want on top! The secret to this blueberry oats recipe is the jammy blueberries, they are truly the star of the show and they only take about 30 seconds to make. 30 seconds! I’ll tell you how and why below!

How to get oats thick and creamy

This is a common question that I get all the time, and it really comes down to the size of your oats and how long you cook them.

What I mean by “size of your oats” is how much surface area the rolled oats have when you begin to cook them. Oats by nature absorb moisture, so just like with any grain, the more surface area they have, the more they can expand and thicken. Quick oats are just a blended-up version of rolled oats, so there’s no need to worry about them being “processed”! The finer your oats, the thicker they will get in a shorter amount of time. This is why I blend up my oats.

After I blend my oats, then the cooking time comes into play. For years I used a stovetop to cook my oats, but now I use the microwave for convenience. Here are my three big tips:

  1. Use a gigantic bowl. I don’t make small serving oat recipes, so these oats will expand like crazy! Using a big bowl will help avoid overflow (which we all know… is the worst).
  2. Cook only one minute at a time, stirring each minute – this is important so the oats don’t clump and so that you get a thick, even texture.
  3. I only need to cook my oats for about 3 minutes, but feel free to go up to 5 or 6 minutes to get your desired texture! The longer you cook, the thicker your oats will be.

Why add water after the oats are done cooking?

This is another common oatmeal FAQ from all the people who have watched my Instagram stories or seen my Pinterest pins. When my oats are out of the microwave and fully cooked, I still tend to add water about 1-2 tablespoons at a time as I add my toppings. This is for a few reasons:

  1. These oats are THICK, and sometimes a little water helps cool them off and get them to a texture that I prefer (which is still thick, but not as thick, y’know?)
  2. I’m all about extra hydration, and as you add water, the oats will quickly absorb it into the already emulsified mixture. It’s a great way to get some extra water and not even notice.
  3. When I add things like flaxseed or chia seeds to my oats, they absorb moisture as well. So adding water helps keep my texture consistent and gives me more hydration and also gives me the most benefits from those seeds as possible.

How to make jammy blueberries

Now for my favorite oatmeal life hack, and the one that might change the game for you: Buy frozen fruit for your oatmeal.

And if you are wondering why, it’s for a simple but game-changing reason. Fruits are comprised of mostly water, so when they are frozen, the water expands, causing the cellular walls of the fruit to expand as well. When you thaw that fruit, this causes the moisture in the water to release, breaking down the cellular walls and creating this juicy, rich, sweet, jammy texture. It’s like getting a sweet, juicy version of your favorite fruit, but without having to do anything complicated with a stovetop or added sugar. It’s my biggest life hack and the key to all my best oatmeal recipes!

So how do I make my jammy blueberries? Easy:

  1. Take about 1 cup (or 140 grams) of blueberries.
  2. Microwave them for about 20-30 seconds or until they are thawed.
  3. OR you can cook them on the stovetop on medium heat with 1 tablespoon of water. Cook for about 1-2 minutes or until thawed.
  4. Give them a quick stir to release the juices, and top your oats!

And that’s everything for these Jammy Blueberry Oats!

If you make it, please tag me on Pinterest or Instagram so I can see! It’s my favorite thing to scroll through stories and see what you all are making.

And of course feel free to leave any questions, comments or reviews! This is the best place to reach me, and I’d love to hear from you <3

Ingredients

  • 2/3 cup rolled oats
  • 1 cup frozen blueberries
  • 1 tablespoon flax meal
  • 1/2 teaspoon cinnamon
  • 1 pinch salt
  • 1 tablespoon peanut butter
  • 1 tablespoon maple syrup, optional
  • 1 tablespoon pumpkin seeds, optional

Instructions 

  1. Add your oats to a small blender and blend them into a fine powder.
  2. In a bowl that can hold about 6 cups, add your oats and 2 cups of water. Stir to combine and get rid of any clumps.
  3. Microwave the oats one minute at a time, stirring each minute. They should look clumpy after minute one, then smoother after minute two, and very thick and smooth after minute three. If you want your oats thicker, keep repeating the process until you get your desired consistency.
  4. After the oats are done cooking, add in the flax meal, salt, cinnamon, 1/2 cup of blueberries and 1/4 cup of water. Stir vigorously to combine. Let the oats sit to thicken while you do the next step.
  5. Take the other 1/2 cup of blueberries and microwave them for 20-30 seconds until they are thawed and jammy (you can learn more about how/why this happens in the blog post!)
  6. Top your oats with the jammy blueberries, peanut butter, pumpkin seeds and maple syrup. Add more cinnamon if you'd like and that's it!

Notes

If you aren’t a fan of microwaves, you can definitely do this on the stovetop too! 
For the oats, set your stove to medium heat and let them simmer. Stir continuously until you get your desired thickness, then follow the rest of the recipe as written. 
For the blueberries, add the blueberries to a small saucepan with 1 tbsp of water. Heat them on medium heat for about 2-3 minutes or until they are thawed and jammy. Follow the rest of the recipe as-written!

    […] Lipstick red strawberry sauce – it would NOT be a strawberry overnight oats recipe without some jammy strawberries! My favorite trick to do this is to use frozen berries that release their natural moisture when you heat them, creating a jammy, juicy texture with no added sugar or extra fuss! You can read more about the science in my Jammy Blueberries Oatmeal recipe! […]
