Oat milk tastes great in smoothies! It has a subtle oatmeal flavor and creamy consistency. This oat milk smoothie is only three ingredients and works with any frozen fruit.

Oat Milk In Smoothies:

There are SO many plant-based milk options, it’s exciting and borderline overwhelming. If you’re unsure where to start, give oat milk a try!

Oat milk is a great option because it’s similar to dairy milk in taste and consistency. It’s fortified with important B vitamins like riboflavin and vitamin B12, plus it’s a good source of soluble fiber.

This oat milk smoothie is only three ingredients: banana, frozen fruit, and oat milk. I used strawberries (a fave!), but any combination of frozen fruit works great!

Key Ingredients:

banana, frozen strawberries, and oat milk.

Banana – A banana creates a luxuriously smooth texture! Ripe bananas lend the most sweetness. When a banana ripens, it’s starch converts to sugar, making it ultra sweet and creamy.
Frozen fruit – I used frozen strawberries, because I live for them! But this recipe works great with mixed fruit, mixed berries, mango, pineapple, blueberries, or cherries. You literally can’t go wrong!
Oat milk – Each brand of oat milk varies in flavor. Some have a stronger aftertaste than others (and not in a good way!). I highly recommend trying a couple brands to see which one you like best. I’ve enjoyed Chobani, Oatly, and Silk brands.

How to Make an Oat Milk Smoothie:

This smoothie with oat milk is a breeze to make!

Combine ingredients: Combine the banana, frozen fruit, and oat milk in your blender. Always start with the soft ingredients! It gives the blades something to catch and reduces stalling. The liquid can go in last. It sinks to the bottom anyway.
Blend: Start the blender on low, then immediately increase the speed. Blend until smooth!

Adjust: IMHO, a smoothie should be thick yet pourable. If it’s too thick, add more liquid, a little bit at a time, until you reach the desired consistency.
Serve: Pour into glasses and enjoy immediately! This makes two small smoothies or one large smoothie.

Recipe Tips:

Make sure you like the brand of oat milk first! Chances are, if you think the flavor is gross, it won’t taste great in a smoothie either. Some brands taste delicious and others taste watered down and cloyingly sweet.
Order matters. I say this often, but it’s worth repeating. It’s easier on your blender when you add the soft, unfrozen ingredients first. Especially if you use a regular, low-powered blender!

Storage:

Smoothies are BEST enjoyed fresh and frosty cold! This smoothie takes 2 minutes to whip up so there’s really no downside.

If you insist on making it ahead of time, pour it into a vacuum insulated cup and store in the fridge for up to 24 hours.

Ways to Add Protein:

This oat milk smoothie is made with plant-based ingredients. It’s dairy-free and vegan with no milk or yogurt. That being said, it’s low in protein with only 3 grams of protein per serving.

Here’s a few ways to amp up the protein:

Nut butter – Add a scoop of almond or peanut butter! Or add a handful of whole nuts, like sliced almonds, pistachios, or cashews.
Plant-based protein powder – There are tons of plant-based options! Look for a high-quality vanilla protein powder without tons of additives.
Seeds – Add a tablespoon of chia seeds, hemp hearts, or flax meal. You can buy a big bag of hemp hearts at Costco!

Variations:

Fruit – You don’t have to use strawberries. Mixed fruit, mixed berries, peaches, mango, pineapple, and blueberries are all good options!
Liquid – You don’t have to use oat milk. Try almond milk, cashew milk, soy milk, or juice! Apple, passion fruit, or orange juice are good options. Orange juice creates a tangier end result.
Sweetener – If you like a sweeter smoothie, consider swapping half of the oat milk with juice. Or add a teaspoon of maple syrup, honey, or light agave.
Greens – For a boost of iron and micronutrients, add a handful of baby spinach. It has a mild flavor that doesn’t overpower the smoothie.
Oats – Add 1/4 cup of rolled oats for added whole grains and a subtle oatmeal flavor!
