8 Blueberry Oatmeal Smoothie

🫐 Ingredients

Blueberries: The base of this smoothie, I’m using frozen blueberries but fresh also work
Banana: Adds a creamy texture; I’m using a frozen banana to eliminate ice (but you can also use room temperature banana and then add in ice so the smoothie is cold).
Oats: Either rolled oats or quick oats are best; you can use steel cut, but you’ll have a much grainier texture
Milk: We’re using oat milk, but any milk or milk alternative works
Add-ins: Ground flax seeds, vanilla extract, and ground cinnamon for a boost of flavor and nutrients
Garnishes: A few blueberries and a sprinkle of oats
Ice: Optional; if you freeze the fruit you don’t need ice but if you want ice then 1/2 cup per serving
Recommended tools: high powered blender

♻️ Sustainable kitchen tips

Take advantage of fresh blueberry season. Fresh blueberries are typically in season during the summer months, which is June through September in the the US and most of the northern hemisphere.

Use dried or frozen berries in the offseason. On the off season, you can use frozen or dried blueberries in this recipe.

Freeze bananas for smoothies. Slice, freeze, and store very ripe bananas to easily grab for future smoothies or even baked goods.

Buy oats in bulk. Oats are one of the best pantry staple ingredients to buy in bulk, so stock up on a pound or two when purchasing to decrease packaging waste.
