This Lemon Smoothie is so bright and refreshing, that you truly will feel (as I do) that it’s like sunshine in a glass. It’s just the right balance of tart and sweet. Fresh lemon juice and zest give it plenty of lemon flavor, while yogurt and frozen banana make it rich and satisfying without feeling heavy. It makes a great breakfast, a pick-me-up snack, or a light, refreshing dessert.

Whip one of these up whenever you need a little something. You can adjust the sweetness to taste, make it super creamy, or add a protein boost if desired. Any way you make it, it’s sure to be a delicious addition to your day.
I’ve never been a huge smoothie person due to all the heavy carbs and oxalates in so many of them. However, once my son developed this delicious Strawberry Avocado Smoothie, that changed.
And now this Lemon Smoothie is really something special. I pretty much smile every time I make it and like me, I think you’ll keep coming back for more!

A little vanilla helps round everything out, while the sweetener lets you adjust the tartness to your preference.

Ingredients

- Sweetener: Honey or maple syrup as written, or another sweetener to taste.
- Milk: Dairy or nondairy milk.
- Chia seeds: Adds body and nutrition.

Recipe Tips
- Adjust sweetness to banana ripeness. I prefer using a less-ripe banana, which has a lower glycemic index and more resistant starch than a very ripe banana. Add sweetener to taste; I like to top off the sweetness with a little stevia extract, stevia glycerite, or monk fruit extract.I top the sweetness off with a bit of stevia extract, stevia glycerite, or monk extract.
- Use both fresh lemon juice and zest for bright lemon flavor.
- For a thicker smoothie, reduce the milk.
- For a thinner smoothie, blend in a little additional milk.
- If refrigerated and reblended with fresh ice, remember that the new ice will dilute the lemon flavor and sweetness. Adjust lemon and/or sweetener as needed.
Variations
- Dairy-Free: Use dairy-free yogurt and non-dairy milk. Cocojune yogurt is a great option: lots of cultures and so thick! If the yogurt is low in protein, protein powder can be added if desired.
- Lower-Carb / Keto: Use an appropriate lower-carb yogurt and a low-carb sweetener such as stevia or monk fruit. For a truly lower-carb version, replace the banana with a lower-carb thickener like frozen cauliflower rice or avocado.
- Higher-Protein: Add vanilla or unflavored protein powder, especially when using a lower-protein dairy-free yogurt. Note that protein powder may thicken the smoothie, so additional milk may be needed.
- Lemon Smoothie Bowl: Reduce the milk for a thick, spoonable version and add toppings as desired.
- Lemon Berry: For a bright lemon-berry variation, add your favorite berries to the smoothie before blending. The berries add a little extra sweetness and a fresh fruity flavor that pairs well with the lemon.

Storage/Make Ahead
- Best enjoyed immediately for the thickest, frostiest texture.
- Can be refrigerated in a sealed container for up to about 24 hours, but the texture will change as the ice melts. Chia may also thicken the smoothie further as it sits.
- If re-blending, shake or stir well before drinking. You might need to adjust lemon flavor and sweetness because added ice dilutes the smoothie.
- Leftovers can also be frozen into smoothie cubes and re-blended later with milk as needed.
