Cottage Cheese Berry Protein Smoothie

Cottage Cheese Berry Protein Smoothie

This high-protein smoothie offers a refreshing and easy low-carb breakfast alternative. While not strictly "keto," it remains low in carbs and, with its high protein content, keeps you full longer—making it an excellent choice for busy mornings. It's the ideal second meal option for those who practice intermittent fasting.

The smoothie gains its extra protein punch from cottage cheese and collagen powder. Cottage cheese, a surprising but effective ingredient in smoothies, creates a smooth, frothy texture without any aftertaste, ensuring its presence is undetectable once blended.

For an added boost, magnesium powder is included to enhance electrolyte balance, promoting energy and hydration throughout the day.

How To Make Cottage Cheese Protein Smoothie

This Cottage Cheese Berry Protein Smoothie is so easy to make. You'll only need a few ingredients:

  • Cottage Cheese: The cornerstone of this recipe, it ensures a creamy, high-protein smoothie without any aftertaste.
  • Collagen powder: Boosts the protein content and adds to the smoothie's creaminess. Options include plain or sugar-free flavored collagen, such as Vanilla Collagen Peptides from Perfect Keto. Alternatively, whey protein powder (isolate) or egg white protein powder can be used.
  • Cashew Milk: Unsweetened cashew milk, almond milk, or even water are suitable (although not ideal as it lacks potassium). For a nut-free version, try Poppy Seed Milk or Coconut Milk (light).
  • Berries:Frozen berries add creaminess and versatility. Choose from strawberries, raspberries, blackberries, or wild blueberries for a flavorful smoothie.
  • Magnesium Powder: Provides an electrolyte boost. Neutral tasting options like Natural Calm work well, or for added flavor, Raspberry-Lemon Calm can be used.
  • Low-Carb Sweetener (optional): To adjust sweetness, stevia or Allulose are recommended, with a variety of options and conversions available here.
  • Vanilla Extract (optional): Not necessary if using flavored collagen powder.

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 smoothie recipe. Here are a few tips:

  • Need more fat/calories? Add a tablespoon of MCT oil or some heavy whipping cream.
  • Need less protein? Skip the collagen powder.
  • Need fewer carbs? Use 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 own macros and preferences.
