Blueberry blended overnight oats are full of fiber and have protein making it a perfect breakfast. You will especially like this breakfast for hot summer mornings when you want something that is cool and easy.

What you’ll need (and why it’s good for your gut)

Oats

Oats are prebiotic rich food which means it has a specific fiber, called beta-glucan, and it can help feed your good gut bacteria. This fiber also has research looking at how it can benefit your heart health too.

Chia

Chia seeds are one of the most fiber filled foods. The fiber in these little seeds is what makes them swell up when you add them to a liquid. Chia seeds are also a source of plant-based omega-3s which are anti-inflammatory.

Kefir

Kefir is fermented milk that has live and active cultures which means it delivers good bacteria to your gut. Plus kefir adds protein which means these blended oats will help keep you full. Kefir has a thicker texture than milk but thinner than yogurt so it works really well with oatmeal and smoothies.

Blueberries

Blueberries are one of my favorite berries because they are rich in antioxidants which benefits your heart and brain health. They are also a great fiber food and there is emerging research on how blueberries can help your gut microbiome.

Lemon

The lemon adds a little acidity which brightens the flavors of the blueberries.

Honey

Honey is a great sweetener to use for oat recipes and pairs well with blueberries. Plus honey has prebiotic properties too.

Ginger

Ginger is great for your gut because it is anti-inflammatory plus ginger tea has long been used to help with digestion and nausea. Ps. If you love ginger check out my ginger recipe pack. It includes 12 different recipes from breakfast to main dishes.

Cinnamon

Cinnamon is a classic spice that has possible blood sugar benefits cinnamon along with antioxidant properties. 

Equipment 

Blender

This recipe can get thick quickly so make sure you have a good blender. A Vitamix can is a great blender that is more expensive. This Ninja blender is a great affordable option.

Mason jar

These jars work well because they have their own lid and are portable so you can eat them in the car if you need to.

Blended overnight oats only take 10 minutes to make and will be ready to eat straight out of the fridge.

Variations

There are a few different variations you can make with these blended overnight oats.

Swap the berry.

A lot of different berries would work well but strawberries would be my first pick. Use what is in season or whatever you have on hand.

Sub maple syrup for honey.

Maple syrup goes well with blueberries so it can be a good substitute for honey.

Change the flavor of kefir.

If you want a stronger berry taste you can use blueberry flavored kefir. 

Use fresh ginger.

This recipe uses frozen ginger because frozen ginger lasts longer, is easier to grate than fresh, and melts into the oats. Fresh ginger is just as good as frozen.
