Keto Smoothie

Ingredients & Substitutions

Here I explain the best ingredients for my keto smoothie recipe, what each one does, and substitution options. For measurements, see the recipe card.

Basic Keto Smoothie Ingredients:

• Fruit – I use frozen strawberries to to make the smoothie cold and thick without needing ice cubes. They also happen to be one of the lowest carb fruits on my keto food list. Feel free to use blueberries, raspberries, or blackberries, but you’ll probably need more sweetener. I don’t recommend other fruits, as they’ll be too high in sugar for keto.
• Besti – I use Besti Powdered Monk Fruit Allulose Blend because it dissolves easily and never gets gritty… plus it tastes just like sugar. If you want a liquid option, my Wholesome Yum Keto Simple Syrup works well too, or swap in my Wholesome Yum Zero Sugar Strawberry Syrup (made with real berries!) for an extra berry pop. I don’t recommend most other sweeteners here, including other brands of monk fruit and stevia, because they contain erythritol as a filler — which settles at the bottom and can crystallize.
• Avocado – You won’t taste it at all, but it’s my trick for making the smoothie extra thick, creamy, and packed with healthy fats! I use it in my other avocado smoothie, too.
• Keto Friendly Milk – Regular milk is too high in carbs, so I use unsweetened almond milk to thin out my keto smoothie. You can also use coconut milk, hemp milk, or even mix heavy cream with water.

Optional Add-Ins:

You can totally keep this keto smoothie recipe simple, but if you want to boost the nutrition or switch up the flavor, here are a few add-ins I like:

• Yogurt – Creates a creamier texture. Be sure your yogurt is unsweetened; I recommend using full-fat Greek yogurt or this keto yogurt recipe.
• Protein – A scoop of unsweetened collagen, whey protein powder, or even a spoonful of nut butter (peanut butter or almond butter) can make this low carb smoothie more satisfying. If you add nut butter or nuts, you might need a splash more milk to thin it out. You might also like my protein smoothie recipe if you want a bigger protein boost.
• Vanilla Extract – If you’re not using vanilla almond milk, a splash of extract adds subtle sweetness and depth.
• Chocolate – A few tablespoons of cocoa powder will cover up the strawberry flavor and makes this creamy smoothie taste like a chocolaty treat.
• Veggies – Try a handful of spinach, kale, or even sliced cucumber. I add a little at a time and taste in between, to ensure I don’t start to taste the greens.
• MCT Oil – This oil helps support ketosis and keeps you full longer (source). I only add up to a tablespoon per serving, otherwise it can upset my stomach.
