The Best Keto Smoothie

If you’re following the keto diet, you already know how important it is to stick to those low-carb, high-fat meals. But let’s face it—sometimes, we all crave something refreshing, something that feels indulgent, but still fits into our daily macros. Enter the keto smoothie: a creamy, flavorful drink that’s not only easy to make but can be packed with all the right ingredients to support your low-carb lifestyle.
Now, I’m sure you’ve heard about smoothies that are loaded with fruits, sugars, and unnecessary carbs. But a keto smoothie is different. It’s crafted to help you stay on track with your keto goals, without missing out on that smooth, velvety texture or that sweet taste that makes smoothies so tempting in the first place. Plus, it’s quick—just throw a few ingredients into your blender, and you’ve got a meal or snack that can help curb cravings and keep you energized throughout the day.
What makes a keto smoothie stand out is its ability to combine healthy fats and low-carb ingredients into one satisfying drink. Whether you’re trying to break through a weight loss plateau, need something to refuel after a workout, or just want a delicious breakfast to start your day, this smoothie is a must-try. It’s easy to make, versatile, and incredibly satisfying. The best part? You get all the flavors of a traditional smoothie without the sugar crash later. Sounds like a win, right?
So, what exactly goes into a keto smoothie? Well, it’s all about picking the right ingredients—think creamy avocado, coconut milk, leafy greens, and a few keto-friendly sweeteners if you want that sweetness without the carbs.

Ingredient List
For the Base:
- 1/2 avocado
- 1 cup unsweetened almond milk (or coconut milk)
For the Greens:
- 1/2 cup spinach or kale (fresh or frozen)
For Extra Boosts:
- 1 tablespoon chia seeds
- 1 tablespoon MCT oil (optional)
For Sweetness (Optional):
- 1-2 tablespoons stevia or monk fruit sweetener (or to taste)
For Texture:
- A few ice cubes
Ingredient Notes
- Avocado: I always use a ripe avocado—it gives the smoothie a super creamy texture and a rich flavor that blends perfectly.
- Almond Milk: Unsweetened almond milk is my go-to because it keeps the carbs low while providing a smooth, nutty base. Coconut milk is a great alternative if you want a richer taste.
- MCT Oil: Don’t skip the MCT oil! It’s a fantastic source of healthy fats that help with energy and ketosis, though it’s optional if you’re looking to keep it simple.
- Chia Seeds: These tiny seeds pack a big punch with fiber and omega-3 fatty acids, so don’t skip them—they really boost the smoothie’s nutritional value!
- Sweetener: If you like a little sweetness, I recommend monk fruit or stevia. Both are keto-friendly and don’t spike your blood sugar levels.
Kitchen Equipment Needed
- Blender: To blend everything into a smooth, creamy consistency. I personally love the Ninja Professional Blender—it’s powerful and can handle both frozen greens and ice with ease.
- Measuring Cups/Spoons: For precise measurements of ingredients like almond milk and sweetener. It’s easy to overdo it, so having accurate measurements is key.
- Spoon or Spatula: To scoop out the avocado and stir the mixture if needed. A silicone spatula is great for scraping every bit out of the blender!
- Glass or Cup: To serve your smoothie in. I like using a tall, clear glass so I can admire that vibrant green color.
Instructions
Step 1: Prep Your Ingredients
- Cut the avocado in half and remove the pit.
- Scoop out half of the avocado with a spoon and set it aside.
- If you’re using frozen spinach or kale, measure out 1/2 cup. If using fresh, pack it lightly into the measuring cup.
Step 2: Add the Base Ingredients to the Blender
- Pour 1 cup of unsweetened almond milk (or coconut milk) into the blender.
- Add the 1/2 avocado to the blender.
- Toss in the spinach or kale.
Pro Tip: If you want a thicker smoothie, you can add more avocado or a little extra almond milk. Start with the suggested amount for a balanced texture.
Step 3: Boost the Smoothie with Extras
- Add 1 tablespoon of chia seeds for extra fiber and omega-3s.
- If you’re using MCT oil, add 1 tablespoon for an energy boost.
- Drop in a few ice cubes to make the smoothie refreshing and cold.
Step 4: Sweeten to Taste (Optional)
- Add 1-2 tablespoons of stevia or monk fruit sweetener to taste. Start with a small amount and blend. You can always add more if you prefer a sweeter smoothie.
Pro Tip: Blend and taste before adding more sweetener. The avocado and almond milk might give you a naturally creamy base that doesn’t need much sweetener.
Step 5: Blend Until Smooth
- Secure the blender lid tightly and start blending on medium speed.
- Gradually increase to high speed until the smoothie is fully blended, and you see a smooth, creamy texture.
Pro Tip: If the smoothie is too thick, add a splash more almond milk or water to thin it out, and blend again. You can also add more ice for a thicker texture.
Step 6: Serve and Enjoy!
- Pour your smoothie into a glass.
- For a finishing touch, sprinkle some chia seeds or cinnamon on top for extra flavor and texture.
Pro Tip: Use a clear glass to show off that vibrant green color—it’s as good as it looks!

Tips and Tricks for Success
- Use Fresh Ingredients: Fresh spinach or kale gives the best flavor, but frozen works well too if you’re looking for a colder, thicker smoothie.
- Balance Your Texture: If your smoothie is too thin, add more avocado or ice cubes. If it’s too thick, add a little more almond milk to get the right consistency.
- Experiment with Sweeteners: If you’re not a fan of stevia or monk fruit, try adding a few drops of liquid erythritol or a small amount of unsweetened cocoa powder for a different twist.
- Make it a Meal: To make the smoothie even more filling, add a scoop of protein powder or a tablespoon of peanut butter for extra protein and flavor.
- Prep Ahead: For a quicker morning routine, prep the dry ingredients (spinach, chia seeds, sweetener) in a container the night before. In the morning, just add your avocado, almond milk, and ice.
Ingredient Substitutions and Variations
- Almond Milk: Swap it with coconut milk or even unsweetened heavy cream if you prefer a richer, more indulgent smoothie.
- Spinach/Kale: Use any leafy greens you like—swiss chard, arugula, or even frozen cauliflower works great for an added veggie boost.
- Chia Seeds: Substitute chia seeds with flaxseeds or hemp seeds for a different texture and nutritional profile.
- MCT Oil: If you don’t have MCT oil, you can use coconut oil or even grass-fed butter for that extra fat boost.
- Sweeteners: Instead of stevia or monk fruit, use a small amount of erythritol, or try a drizzle of sugar-free maple syrup for a different flavor.
- Add-ins: For a chocolate twist, add 1 tablespoon of unsweetened cocoa powder. For more flavor, try vanilla extract or a pinch of cinnamon.
Serving Suggestions
- As a Quick Breakfast: I love enjoying this keto smoothie as a filling breakfast on busy mornings. It’s the perfect start to my day, keeping me full until lunchtime without the carbs!
- Post-Workout Refuel: After a workout, this smoothie is my go-to for replenishing energy. The healthy fats and chia seeds help repair muscles while keeping me in ketosis.
- Midday Snack: When I’m feeling a bit sluggish around 3 PM, this smoothie is a refreshing, low-carb pick-me-up that helps me stay on track with my keto goals.
- With a Side of Nuts: Pair this smoothie with a small handful of almonds or walnuts for a little extra crunch and protein. It makes a great snack or light meal!
- As a Dessert: If you’re craving something sweet after dinner, this smoothie works as a healthy dessert. Add a sprinkle of cocoa powder or cinnamon to make it even more indulgent!

Storage and Reheating Instructions
- Storage: Store leftover smoothie in an airtight container in the fridge for up to 24 hours. The smoothie may thicken slightly as it sits, so give it a good stir before drinking.
- Freezing: If you have extra smoothie, pour it into ice cube trays and freeze for later. You can blend the cubes with a bit more almond milk when you’re ready for a quick snack or meal.
- Reheating: This smoothie is best enjoyed cold, so I don’t recommend reheating it. If it gets too thick in the fridge, just add a splash of almond milk and blend again to restore its creamy texture.
