Keto Low Carb Blueberry overnight oatmeal recipe

Blueberry Overnight Oatmeal Recipe

We love our oatmeal recipes here. We’ve had brownie batter oatmeal, carrot cake oatmeal, and my favorite chocolate chip cookie dough overnight oats

With blueberry season in full swing, I knew I had to add them to this classic overnight oatmeal.

Traditional overnight oatmeal (or even crockpot or instant pot oatmeal) is made with rolled oats and milk. My version is actually made without oats! Often referred to as ‘oatless oatmeal’ or ‘paleo oatmeal’, it is a low carb hot cereal option! 

Can you eat oatmeal on keto?

Oatmeal, along with other grains, is not allowed on a ketogenic diet. They are too high in carbohydrates which would put anyone out of ketosis. Instead, there are other options to have ‘oatmeal’ on a keto diet. 

Is there a keto friendly oatmeal

A keto diet oatmeal has been created here, and perfect to satisfy your oatmeal or hot cereal cravings, minus the carbs and grains!

Instead of rolled oats, a combination of chia seeds, flaxseed, and shredded coconut are combined to produce a thick, creamy and hearty texture. 

Perfect hot or cold, it’s the best low carb cereal option, that also happens to be vegan, gluten free and sugar free! 

Easy Keto Overnight Oatmeal recipe with blueberries

How to make keto blueberry oatmeal 

Step 1- Prepare your oatmeal base

Prepare your keto overnight oatmeal base by combining your dry ingredients and mixing well. Add half a cup of hot water or hot milk and mix well. Add half a cup of cold milk/water and mix again. 

Step 2- Mix through half your-add ins

Stir through half the fresh blueberries, a tablespoon of sugar free blueberry jam and if desired, some crumbled up pieces of blueberry breakfast cake (or one of my blueberry streusel cookies!). 

If the oatless oatmeal is too thin, add some extra chia seeds to it. 

Step 3- Refrigerate overnight

Place the blueberry overnight ‘oatmeal’ in the fridge overnight, for it to thicken. If you want to enjoy it sooner, you can check up on it after 3 hours. 

Step 4- Mix and enjoy! 

Remove the blueberry oatmeal from the fridge and if it is too thick, add some extra milk. Once you have achieved the desired texture, add extra blueberries and other ingredients of choice (I LOVE some mixed nuts and grain-free granola!).

Can I use regular rolled oats if I am not keto? 

If you don’t follow a keto or paleo diet, you can easily make this recipe with oatmeal (it will still be vegan and gluten-free!).

Simply prepare my overnight oatmeal base, and add in the ingredients as listed! 

Can I heat up overnight oatmeal? 

You can enjoy this overnight blueberry oatmeal warm if desired.

Prepare the oatmeal as instructed, and add an extra 1/4 cup of milk. Either microwave for 1-2 minutes, or in a small saucepan. 

If the hot cereal is too thin, add extra chia seeds to thicken.

  1. Oh wow, this looks fantastic! I seriously need to try out your keto oatmeal base, but you truly can’t ever go wrong with conventional oats or any suitable grain for this recipe. Blueberries in oatmeal are always a splendid addition–but I genuinely believe everyone has to try your blueberry breakfast bake too!
