Some smoothies are a little too watery, but this berry smoothie? It’s the thick and creamy kind you’ll actually crave. As someone who’s always looking for easy ways to refuel after my workouts—whether it’s a morning run, tennis match, or strength session—I rely on smoothies to pack in nutrients without a ton of effort.

This recipe for a mixed berry smoothie is thick, creamy, and ready in just five minutes, using frozen berries so you can enjoy peak-season flavor year-round. It’s naturally protein-rich from whole food ingredients (no protein powder required), with easy variations to add even more protein if you’d like. Let’s get into it!

Key Ingredients + Notes

• Frozen bananas and berries - I usually slice and freeze my bananas at peak ripeness (or just after), but never when they're overripe (that's when it's time to make spelt flour banana bread!). For berries, I mostly buy organic frozen berries from the store, but you can also freeze fresh berries.
• Greek yogurt - This is our main source of protein in this smoothie recipe! If you want to make a completely plant-based smoothie, feel free to use a high protein plant yogurt, such as the kind from Kite Hill or Siggi's plant-based yogurt. Feel free to choose vanilla yogurt or add in some vanilla extract to make this a berry vanilla protein smoothie!
• Milk - Milk is our other protein source, and it can be whatever kind you like! For dairy milk, I've been loving A2 milks from Alexandre Farms. For plant milks, I'm obsessed with Elmhurst milks because they don't use added gums or fillers, and they also use a zero-waste process to make their milks.

If you're looking for a protein rabbit hole, I talk more about finding high protein milks in my high protein overnight oats recipe as well!

Let's Make This Berry Protein Smoothie

1. Step 1: Place all ingredients into a high-speed blender.

2. Step 2: Blend on high until completely smooth, adding more milk if too thick. Pour into a glass and top with more berries and optional superfood toppings like chia seeds, cacao nibs, or coconut chia granola!

If You Want to Add Even More Protein...

Yogurt, milk, and hemp seeds are our main source of protein in this smoothie recipe, but you can add even more if you'd like!

• Protein powder - Feel free to add your favorite protein powder to boost protein. Plain or vanilla protein powder work best for this recipe.
• Nut butter - A tablespoon or two of almond or cashew butter is delicious in berry smoothies, and adds 4-8 grams of additional protein.
• Kale - It's not a mass amount of protein, but adding in a handful can add 2-3 grams of protein! Pretty good for a veggie.

Sustainability Tips

• Use up greens. If you do have some kale or spinach that needs to get used up before it gets thrown away, smoothies are the perfect opportunity to do that! Even if you're not quite ready for a smoothie, you can freeze your greens so they are ready when you are. Even herbs can be delicious to toss in (like in my mango mint smoothie!).
• Freeze fresh berries before they go bad. We usually demolish our fresh berries, but I know some friends who buy larger containers and Costco and don't always finish them. If that's you, try freezing the berries before you have to toss them. Then use them in this smoothie!
