Smoothies packed with protein and fiber are a fast and easy way to blend up a meal that you can enjoy an on-the-go meal that’s actually nutritious. This High Fiber Smoothie Recipe with strawberries, spinach, flax, and beans will keep you feeling full and satisfied.
I’m sure you weren’t expecting to see a smoothie recipe that calls for beans, but white beans go undetected in it and are an excellent source of fiber. Many diets fail because women aren’t eating enough protein and fiber. Also, most mainstream diets are unsustainable long-term.
This high fiber smoothie combines fiber-rich fruits and veggies with healthy fats and protein for a nourishing and nutritionally balanced frozen drink. Best of all, it’s easy to customize to your tastes and preferences!

Table of Contents
Ingredients
- Almond Milk: Use any unsweetened plant-based milk to add liquid to the smoothie so it’s blendable and drinkable.
- Frozen Strawberries: You could use fresh or frozen strawberries, but frozen strawberries give it a creamier and colder consistency and eliminate the need for ice.
- Protein Powder: A scoop of your favorite plant-based protein powder gives this smoothie an added protein boost. Use vanilla protein, or any other flavor you prefer.
- White Beans: You could use any type of bean, but I’ve found that white beans and chickpeas are the best because they don’t add much bean flavor. Be sure to drain and rinse your beans well before adding them to your smoothie!
- Cauliflower Rice: Not only is this low-carb rice alternative loaded with fiber and nutrients, but it also gives the smoothie a frothy texture and doesn’t alter the taste.
- Spinach: Add some greens to your smoothie with fresh spinach, which is also full of fiber as well as nutrients like iron.
- Ground Flax: Healthy fats are necessary for balanced nutrition. Flax is not only a healthy fat, but it’s also high in fiber.

Variations & Dietary Modifications
- Try Other Vegetables: This high fiber high protein smoothie recipe is incredibly versatile. Instead of spinach, try making it with kale, zucchini, carrots, or beets. The fiber content with vary with the different veggies, but they are all loaded with nutrients.
- Use Different Fruits: Instead of strawberries, you can make this smoothie with blueberries, blackberries, cherries, pineapple, or melon, depending on the flavors you prefer.

Recipe FAQs
Sure! You can blend up your smoothie and keep it in a blender cup in the freezer for up to 5 days. It will definitely need to thaw before you can enjoy it though. Another option is adding all of the ingredients to a freezer bag, minus the liquid, so you just have to dump the bag and blend it in the morning.
Protein powder can make smoothies a little gritty if it isn’t blended well. Try blending the liquid and protein by themselves first, then add the other ingredients. This gives the protein the chance to blend well and not stick to the fruits and veggies.
It may not have blended well enough, or there wasn’t enough liquid. You can add another splash of milk and blend it until it’s silky smooth. Don’t forget to properly layer the ingredients so the liquid is closest to the blender blades.
