Green Keto Smoothie - Packed with Veggies
What protein powder can I use in this green keto smoothie?

Absolutely! Feel free to blend in your choice of protein powder. Whether it’s grass-fed collagen, whey protein isolate, egg white protein isolate, or a plant-based option like pea protein, it will integrate seamlessly for an extra protein boost.

What other add-ons can I use?

a teaspoon of vanilla extract is a great choice to add flavor, and 1-2 tablespoons of MCT oil is a great option for extra energy.

I have a nut allergy; how can I make this smoothie nut-free?

For a nut-free version, simply omit the cashews or almonds, or use some sunflower seed butter or coconut butter. As a result you won’t lose any of the creaminess, thanks to the avocado and coconut cream.

Is this smoothie suitable for those avoiding dairy, eggs, or nightshades?

Yes, this green keto smoothie is naturally dairy-free, egg-free, and nightshade-free, making it ideal for any dietary preferences and allergies.

What are the best sweetener options for this green keto smoothie?

To keep it low-carb, I recommend using stevia, monk fruit, or allulose. Adjust the sweetness according to your taste. Each of these sweeteners works well without affecting the blood sugar levels significantly.

What if I need to avoid high oxalate ingredients?

For those managing their oxalate intake, consider skipping the spinach. You can also replace almonds or cashews with macadamia nuts, sunflower seeds or coconut butter (coconut manna) to keep it creamy yet lower in oxalates.

How To Make Green Keto Smoothie

Prepare the Pumpkin in Advance. Cut the pumpkin into 1-inch (2.5 cm) cubes and steam until tender, about 20 minutes. Allow to cool, then place on a lined tray and freeze for at least 2 hours or overnight.

Prepare the Zucchini and Broccoli in Advance. Slice the zucchini into 1.5-inch pieces and cut the broccoli into florets. Spread them over a tray and freeze for at least 2 hours or overnight. (No need to pre-cook although you could briefly steam if you prefer.)

Place Everything in a Blender. To make the smoothie, place all the frozen vegetables and the remaining ingredients into a high-powered blender. Optionally, add some MCT oil, or a splash of vanilla for added flavor.

Blend and Serve. Process until the mixture is smooth and creamy. If the smoothie is too thick, add more water or unsweetened almond milk to reach your desired consistency. Serve immediately for the best flavor and texture. Sweeten to taste if needed.

Tips for Best Green Keto Smoothie

  • Prep in Bulk for Convenience: Take some time to prep and freeze larger amounts of pumpkin, zucchini, and broccoli. You can also stock up on frozen spinach. This not only saves time on busy mornings but ensures you always have the ingredients on hand for a quick smoothie fix.
  • Blend it Super Smooth: Keep blending until there’s no lumps left. It makes everything creamier and hides the veggie bits well.
  • Throw in Some Yummy Protein: A scoop of chocolate or vanilla protein powder can make your smoothie taste more like a treat.
  • Sweeten as You Like: Play around with sweeteners like stevia or monk fruit to get it just right for your sweet tooth.
  • Ease Into the Greens: Even if you’re not a fan of greens, you can start small with the veggies and ramp up as you get used to them (neutral tasting pumpkin and zucchini are great options to start with).
  • Spice to Surprise: A little cinnamon or nutmeg can also add a nice twist that makes the greens way less noticeable.
  • Keep it Chilly: Use frozen veggies to keep your smoothie cool and thick—like a frosty treat on a hot day.

Storage Instructions

Can I make this green keto smoothie ahead of time?

It’s best enjoyed fresh, but if you need to, you can make it ahead and store for up to a day. Just keep it in the fridge and give it a good stir or a quick blend before drinking as it might separate a bit.

What about prepping the veggies ahead of time?

Absolutely! Chop and freeze your veggies in advance. This way, you can just grab them out of the freezer, and then toss them into your blender, so you have your smoothie ready in no time. It’s a great meal prep hack!

Tools for Green Keto Smoothie

  • Blender: A high-powered blender is essential for handling the frozen veggies and blend everything together seamlessly. As a result you’ll get really smooth, creamy texture.
  • Freezer Bags: Great for storing your pre-chopped veggies. Use these to keep everything fresh and organized in your freezer, so that you can make your smoothie prep super quick and easy.
