Blueberry Chia Oatmeal

Jump to Recipe Print Recipe

Okay, these might just look like average blueberry oats, but this recipe is how I get my oatmeal the perfect texture every time. It’s also sneakily filled with great ingredients. I love a Blueberry Oatmeal with Flax and Chia because you get filling fiber, protein and a great texture baked into one (even though there is no baking).

I first shared this recipe years ago as a quick breakfast for busy mornings, but it’s since evolved into something more satisfying and substantial. It’s loaded with fiber, omega-3s, and antioxidants, thanks to a triple threat of chia seeds, flax meal, and blueberries. The cinnamon gives it muffin vibes, the flaky salt wakes everything up, and the maple syrup ties it all together.

You know I take my oatmeal recipes very seriously, because why give a recipe for something most people eyeball? And my answer is: I give a recipe when I think it’s really worth it. The ratios here are worth it.

This recipe is not only about the texture of the oats, but it’s about the ingredients. I think too often we sleep on ingredients like chia or flax because we see them as tasteless fluff, but they can add SO much to a bowl of oats, both with nutrition, and also with satiety and texture.

I’ll detail out how to make this bowl as well as the timing and tricks below.

Why you’ll love this Blueberry Oatmeal

  • Tastes like a blueberry muffin—but make it breakfast.
  • Naturally sweetened with maple syrup and bursting with whole blueberries.
  • High in fiber and healthy fats, so it actually keeps you full.
  • Comes together in 10 minutes with pantry staples.
  • Works with frozen or fresh blueberries (hello, year-round oatmeal!).

Ingredients you will need for these blueberry oats

  • Old-fashioned rolled oats – for that creamy-but-not-mushy bite.
  • Chia seeds & flax meal – to thicken, nourish, and add staying power.
  • Water – it keeps the oats lighter and lets the flax/chia do the heavy lifting.
  • Blueberries – fresh or frozen both work. Some will melt into the oats and some will stay whole, which adds more natural sweetness.
  • Cinnamon – adds warmth and that blueberry muffin flavor.
  • Flaky salt – essential for balance, and a little fancier than normal salt, but so worth it.
  • Maple syrup – because we like our oats sweet here!

How to cook your oats

One of the most common questions I get about cooking my oatmeal is how do I get the perfect texture. I used to overthink this – talking about stirring and checking and adding water at different times.

Now, I keep it simple: make sure to cook your oats long enough, and thin them out with hot water if your texture feels to thick.

I’d always rather err on the side of really thick oatmeal that I can thin out, rather than oatmeal that feels watery.

How to make the best blueberry oatmeal (in minutes!)

Combine your base. In a bowl or small saucepan, mix the oats, chia seeds, flax meal, and water.

Cook it your way.

  • Stovetop: Simmer over medium heat for 4 minutes, stirring occasionally.
  • Microwave: Heat on high for 4 minutes in a large bowl (it will expand!).

Stir in the flavor. Gently mix in the blueberries and cinnamon. Some berries might burst and tint the oats purple—that’s totally fine.

Adjust if needed. If it’s too thick, stir in a splash of hot water to loosen things up.

Finish and enjoy. Top with flaky salt and a drizzle (or two) of maple syrup. Eat right away!

Looking for other oatmeal recipes?

These are a few of my go-to favorites. A lot of them are overnight, but a few use this thickening technique as well!

Bananas Foster Overnight Oats
These oats are quick, easy, delicious and filled with all the caramely notes of one of my favorite desserts, bananas foster, but with none of the rum and flambé-ing part 😉

Zoats | Zucchini Oatmeal
This used to be a favorite of 2016 diet culture – but let's improve it and make it our own. Just because I'm anti diet-culture doesn't mean I'm anti-veggie, and this is the best (and most delish) way to get in your greens or use up an old zucchini!

Apple Pie Overnight Oats
These oats are cooked first for volume, and then allowed to chill overnight. You get that great cold overnight oat taste, but the same hydrated chia seeds and cooked oat benefits. These apple oats are simple, delicious and perfect for meal prep. You can make 2 or 4 servings to best fit your week.

Berries & Cream Oatmeal Bowl
This oatmeal bowl is the best way to start your day. Filled with coconut, chia seeds, strawberries and raspberries, this vegan dream will keep you full for hours, plus it has a slight sweetness that is the perfect way to start breakfast. The cream makes it feel like a strawberry shortcake and nostalgia in a bowl!

Recipe tips for this Blueberry Chia Oatmeal

  • If you’re new to flax or chia, this is a great intro. They blend in seamlessly and help the oats set to that perfect thick, spoonable texture. You’ll get all the benefits without any odd texture or clumping!
  • For extra richness, swap half the water for almond milk or oat milk.
  • If you like sweeter oats, go for 2 tablespoons of maple syrup instead of one.

Retired recipe note (updated 2025)

If you’re looking for the older version of this oatmeal you can find it underneath the recipe box. I’ve updated this version in 2025 to reflect how I actually make it now: thicker, heartier, and less complicated.

And that’s it for this Blueberry Chia Oatmeal!

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 & 1/4 cup water
1 tbsp chia seeds
1 tbsp flax meal
1/2 tsp ground cinnamon
1 & 1/4 cup frozen blueberries
1 pinch of salt
1/2 cup hot water set to the side, for mixing
Optional peanut butter for topping  
 
Instructions
Combine the 2/3 cup oats and 1 & 1/4 cup water. Either cook on the stovetop until they begin to thicken, or add them to a very large microwave safe bowl and cook for 4 minutes, stopping every minute to stir.
Remove the oats from the stove or microwave when they have begun to thicken. Add in the chia seeds and flax meal and stir to combine. These seeds are natural thickeners and will immediately begin to absorb water. Let the oats sit for 3-5 minutes so the seeds can absorb moisture and thicken the oats.
If the oats get too thick, dilute with a splash of the hot water you have to the side and give a quick stir to combine.
Once the oats are reasonably thick, add the cinnamon, salt and blueberries. The residual heat from the oats should thaw the blueberries and the oats will turn a purple-blue color as you stir. Feel free to put them in the microwave for another 30 seconds if you want your oats very hot.
Top with peanut butter, more cinnamon and serve.

A Basil Potato Salad. No, I never thought we’d A Basil Potato Salad.

No, I never thought we’d get here, either. 

But I kind of love it - not too heavy, filled with texture, hit with that same (light!) acidic element that we all know a potato salad needs. Take this and impress your grandpa (..idk I feel like family members love a potato salad).

@tillamook Oregon Strawberry ice cream sandwiches, @tillamook Oregon Strawberry ice cream sandwiches, because whenever I make a cookie crust for a pie I’m always wondering why we don’t do the same with ice cream sandwiches? #TillamookPartner
 
And Tillamook has the best ice cream in your grocery store hands down, and I am never without either their Oregon Strawberry or Vanilla Bean. Both taste so creamy and so LUXE. Long live summer and long live Tillamook dairy. If you need me, I’ll be in the ice cream section 🙂‍↕️
 
My recipe can be found on Tillamook’s site, and I hope you make these ice cream sandwiches for a crowd this summer 💚
