This keto smoothie is such a refreshing and easy low-carb breakfast option. It tastes like ice cream but with none of the sugar! It's low in carbs and high in protein to keep you full for longer.

To get that extra protein boost we're using collagen powder, yogurt and eggs. If you haven't tried using raw eggs in smoothies before, it's a game changer. When blended, raw eggs get really frothy with absolutely no odd texture or flavor. And as long as you're using pasteurized eggs, they are safe to consume.

How To Make Keto Protein Smoothie

This Raspberry & Lemon Protein Smoothie is easy to make. Here's what you need and what you can use if you need to make this smoothie egg-free, dairy-free, nut-free or vegetarian.

  • Eggs are a great source of protein and will make this smoothie creamy and frothy. Don't worry, you won't be able to taste them and there will be no slimy texture. If you can't use eggs, you can use 1 tbsp chia seeds or 1-2 tbsp coconut butter or almond butter.
  • Collagen powder is a great source of protein that will make this smoothie even creamier. Instead of collagen powder you can use whey protein powder (isolate) or egg white protein powder. You can even use plant-based protein powder (pea protein powder is a good choice).
  • Almond milk or cashew milk (make sure it's unsweetened) or even water will work in this recipe. If you don't like ice, add more almond milk or water. Full-fat yogurt or coconut yogurt for dairy-free. And if you need to add more fat and make it more satisfying, simply add some heavy whipping cream or coconut cream..
  • Raspberries, ideally frozen for extra creamy texture. If you don't have frozen raspberries, use 2 more ice cubes. You can also use strawberries, blackberries or wild blueberries (go easy on blueberries as they contain twice the amount of carbs!)
  • Lemon zest for extra flavor. Make sure you are using organic, unwaxed lemons. Although not essential, it's highly recommended. Instead of lemon zest you can could use 1/4 tsp of sugar-free vanilla extract.
  • Low-carb sweetener such as stevia, Erythritol, Swerve or Allulose can be used to taste. You can find all options and conversions here.
  • Ice is perfect for hot summer days and will provide extra creaminess. Or you can just add water or more almond milk instead.

Customize Your Smoothie

Each and every one of us has different dietary needs so it's only natural that you may need to adjust the macros in this keto recipe. Here are a few tips:

  • Need more fat? Add a tablespoon of MCT oil or partially replace the yogurt with heavy whipping cream or coconut yogurt.
  • Need less protein? Skip the protein powder (collagen) or use just one egg (or use two egg yolks instead of two whole eggs). You can also reduce the protein content by using heavy whipping cream or almond milk instead of yogurt.
  • Need fewer carbs? Use just half of the amount of raspberries or swap with blackberries for a slightly lower carb count.

You can make all these adjustments and more directly in the KetoDiet App by cloning any of the recipes from my blog and customizing them to fit your macros and preferences.

How To Pasteurize Eggs at Home

If a recipe calls for raw eggs and you are concerned about the potential risk of Salmonella, you can make it safe by using pasteurized eggs.

To pasteurize eggs at home, simply pour enough water in a saucepan to cover the eggs. Heat to about 60 °C/ 140 °F. Using a spoon, slowly place the eggs into the saucepan. Keep the eggs in the water for about 3 minutes. This should be enough to pasteurize the eggs and kill any potential bacteria. Let the eggs cool down and store in the fridge for 6-8 weeks.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

Absolutely delicious! I can confirm that there is absolutely no eggy taste or slimy texture from the eggs if you're worried about any of these. I didn't have raspberries so I used frozen strawberries which work really well with lemon.
I've tried smoothies with cooked eggs before and it was horrible, impossible to drink because I could smell the eggs... Tried all the tips to remove the sulphur smell and nothing worked. Three smoothies later I gave up. The only one that was just about "ok" was a chocolate smoothie but I had to use a lot of cacao powder to beat the eggy taste so it wasn't so low in carbs anymore. If you're planning to use eggs, use them raw!

Thank you Maya! I've tried cooked eggs too but I wasn't a fan either. Much better with raw eggs.
