This Keto Green Smoothie with avocado and spinach is packed with energizing and filling ingredients to keep you satisfied and focused throughout your day. Just toss everything in your blender, pulse a few times, and serve – that’s it! An easy sugar-free and dairy-free breakfast or snack that is low in carbs and full of flavor.
This keto smoothie is creamy and lightly sweet, yet doesn’t include common smoothie ingredients like bananas or other fruits.
Instead, the creamy texture is the result of avocado (fresh or frozen will work), dairy-free milk, and sunflower seed butter or nut butter.
The resulting smoothie is packed with healthy fats, nutrients, protein, and is low in net carbs.
You can even customize the smoothie to your liking – add additional ingredients (recommendations are included in the Variations section below) or omit those that you don’t like or don’t have on hand.

👉 Ingredient substitution suggestions
- Spinach: Kale or swiss chard can be used, but the flavor of the smoothie may be slightly altered.
- Unsweetened Coconut Milk or Almond Milk: Heavy cream or whole milk can be used here at a 1:1 ratio, but note that this will increase the total carb content of the smoothie and the smoothie will no longer be dairy-free. For a dairy-free substitution, use canned coconut cream, but note that this will slightly increase the carb content of the smoothie.
- Powdered Sweetener: Allulose is a good substitute option here; use 1 Tablespoon if you go this route. You can also use a granulated sweetener (like Lakanto Classic Monk Fruit Sweetener or Lakanto Golden Monk Fruit Sweetener). Consider powdering the granulated sweetener in the blender before you start making your smoothie, which will ensure the texture of the smoothie is smooth. Liquid stevia or powdered stevia are also options, but I cannot suggest how much to use as every brand of stevia is so different. If you do use stevia, I would start with a small amount, blend, taste test, then add more stevia from there.
✨ Variations
- Include some celery ribs or cucumber slices for added nutrients.
- Add in some MCT oil, MCT oil powder, or coconut oil for additional healthy fats. (I get my liquid and powdered MCT oil from Perfect Keto – you can use code REALBALANCED for 15% off.)
- Sprinkle in a small amount of unsweetened cocoa powder to yield a chocolatey smoothie (note that this will change the color of the smoothie and will slightly increase the carb content).
- Squeeze in fresh lemon juice for a bright and tangy flavor.
- Add 1 teaspoon of ground flax seeds or chia seeds for added nutrients, healthy fat, and protein.
- Include a few fresh mint leaves and/or a small amount of peppermint extract for a minty green smoothie.
- Add in a handful of fresh or frozen berries (like raspberries, strawberries, or blueberries) for some extra sweetness and tartness (note that this will change the color of the smoothie and will slightly increase the carb content).
- Boost the protein content by adding a scoop of whey protein powder.
➜ Cooking and recipe tips
- Some grocery stores sell frozen avocados, but these are usually priced rather high – but the convenience of them is nice! For this recipe, I like to buy fresh avocados, peel them, slice them into strips, then freeze them. Once I’m ready to use them, I just pop them into my blender straight from the freezer.
- The matcha powder is optional, but I personally would recommend using it! It will yield a smoothie that is very green, as well as provide some delicious flavor and antioxidant benefits.
- If you want your smoothie to be thinner, add more liquid (unsweetened coconut milk, unsweetened almond milk, or even water will work).
- If you added too much liquid, toss in a few ice cubs and the smoothie should thicken back up.
💬 FAQs
How can I make the smoothie sweeter without increasing the carb content?
You can add additional powdered sweetener, which will not increase the net carb content.
How should the smoothie be stored?
This smoothie is best eaten immediately, but it can be stored if you want to meal prep it. Store in an airtight container (like a mason jar) in the refrigerator for up to 1 day. If the smoothie splits during the time it’s stored, just shake it up and everything should combine again.
