Blueberry Lemon Smoothie

Frozen blueberries and a touch of lemon give this smoothie a nutritional boost that'll make you feel like a million bucks. And the best part? It's a crowd-pleaser! Kids love it just as much as adults, so everyone in the family can enjoy this delicious drink.

Oh, you are in for a treat! This Blueberry Smoothie recipe is one of our favorite smoothies and will have you feeling like a smoothie pro in no time. We love my Strawberry Pineapple Smoothie and my Pineapple Mango Smoothie, but when blueberries are in season - you can't beat this Blueberry Lemon Smoothie.

Trust me; it's not just great for a healthy breakfast or snack - it's an all-around winner! Smoothies are great for breakfast, brunch, or a healthy snack.

This Blueberry Lemon Smoothie is so easy to make, and you will only need three ingredients (one being water!) It is a nice refreshing smoothie packed with nutrition. That is why I love making this smoothie.

I love fresh blueberries in the summer months. I usually try to get out blueberry picking with my family each summer so we can bake blueberry banana muffins with them, make smoothies, or just eat them! 

We also love to freeze blueberries (see below for how to freeze them). Frozen blueberries are great for making smoothies, so we try to pick extra just for freezing. This way, we can have them in the middle of the winter when we are dreaming of warm sunny days!  

You need to use frozen blueberries for this smoothie recipe. If you use fresh berries, it will be thin and turn out more like juice than a smoothie. If you don't have any frozen berries in your freezer, you can find them in the freezer department at your local grocery store.

Ingredient List

• Frozen Blueberries
• Fresh Lemon
• Ground Flaxseed (optional)
• Water, Almond Milk, or Coconut Water - If you want your smoothie to have more of a creamy texture, you can use oat milk, soy milk, cashew milk, or your favorite plant-based milk. You can also add a little bit of Greek yogurt or a scoop of protein powder if you want to increase the amount of protein in your breakfast smoothie.

Why this recipe works:

• This smoothie is made of just three ingredients…blueberries, one lemon, and water. Just three simple ingredients in this smoothie.
• Blueberries and lemons are full of health benefits. This is a great post on the benefits of blueberries. It makes me want to have more blueberries!
• It’s kid-friendly! My young daughter loves the smoothies we make, with this one at the top of the list.
• Smoothies are great for any time of the day. Some like them for breakfast and some for an afternoon healthy snack. My family usually has them in the afternoon for a healthy snack. We love to make them with just fruit…nice and light. We don’t usually add milk or yogurt to our smoothies.
• It's vegan! This is a vegan lemon blueberry smoothie as it has no milk products added to it.

How to Make a Blueberry Smoothie

Pour the water into your blender. When using frozen fruit, it is best to add the liquid first, then the frozen fruit. (Use less liquid if you want to make a thicker smoothie.)

Rinse and measure out the frozen blueberries. Slice your lemon in half. 

Place the blueberries into your blender.

Squeeze the lemon juice over the frozen blueberries in the blender. You can also add a little lemon zest if you really want to increase the lemon flavor, but fresh lemon juice is really all you need.

Add in the ground flaxseed (optional).

Blend until smooth. Serve immediately.

Why Use Frozen Blueberries Over Fresh Blueberries? 

Using frozen blueberries will chill the smoothie for you without having to add ice. Adding ice can sometimes lessen the delicious flavor of the fruit. Frozen berries also thicken the smoothie.

Why Add Ground Flaxseed to Your Smoothie?

We like to add ground flaxseed to our smoothies for a source of protein as well as omega-3 and fiber. You can also add whole flax seeds or chia seeds; they will just be a little crunchy.

How to Freeze Blueberries

First, rinse the blueberries. When rinsing them, gently run them under warm water and place them on a paper towel to dry.

Cover a baking or cookie sheet with parchment paper. Place the blueberries in a single layer on your baking sheet and place it in the freezer until they are frozen (about two hours).

Once they are all frozen, toss them into a freezer bag or container and seal it tightly. 

By freezing them this way, the blueberries will not clump together. It will be easier to measure out your blueberries when using them down the road.

This smoothie recipe uses frozen blueberries, so do not thaw them. They can go right into your blender from the freezer.

Blueberries are good in the freezer for up to six months.

Tip: It is a good idea to label your freezer bag or container so that you know what is in there and when you froze them. 

I would love it if you would follow me on Instagram and Pinterest for all of my recipes. 

Recipe Tips

• Pour the water in first…then the frozen berries. The berries will mix in better that way and will also be easier on your blender.
• This recipe makes about three cups.
• If you have any extra, keep it chilled in your refrigerator for up to two days and stir before serving.
