High-Fiber Smoothie Recipe

This high-fiber smoothie recipe is creamy, filling, and packed with ingredients that support gut health and steady blood sugar. A quick and nourishing smoothie recipe perfect for busy mornings

Smoothies have always been one of my favorite breakfasts because I love how much you can pack into one blender! Plus, when mornings feel rushed, tossing a few ingredients into the blender can be the fastest way to get all your nutrition categories in one fell swoop (vegetables included!) I love that a smoothie can feel both refreshing and filling at the same time, and they are my go-to summer breakfast.

Smoothies are also hard to mess up and are so flexible to customize. You can change the fruit, adjust the sweetness, add extra protein, or boost the fiber depending on what your body needs that day. I always recommend a hearty smoothie instead of one made primarily with simple carbs and juice.

Since the blender does some of the breaking down for you, smoothies can sometimes leave you hungry sooner than a “chewable” meal. So I try to include as much fiber and protein as possible to help with that satiety. Sufficient fiber supports gut health, helps digestion run smoothly (ahem!), and can also help keep blood sugar steady after breakfast.

This high-fiber smoothie is one of my go-to smoothie combos, with boosted fiber from oats, berries, spinach, and chia seeds. It’s creamy, naturally sweet from fruit, and full of ingredients that support digestion and overall gut health. Top it with this sugar-free healthy granola recipe for a crunchy topping and even more fiber.

If you’re looking for an easy way to boost dietary fiber without using supplements or eating bran cereal, this smoothie checks all the boxes.

This smoothie recipe calls for simple ingredients like whole milk, fresh fruits, chia seeds, peanut butter, and greek yogurt to create a creamy drink that actually keeps you full. It works great as a quick breakfast, an afternoon snack, or even a light meal after a workout.

Are Smoothies High In Fiber?

Smoothies can contain fiber, but it all depends on what goes into the blender. A basic fruit smoothie made with milk and fruit might only contain around two to four grams of dietary fiber. That’s because many smoothies rely mostly on liquid ingredients and fruit alone.

But with a few additional key ingredients you go from a snack-size to a meal. Using whole fruits instead of fruit juice helps preserve the fiber content, and adding ingredients like chia seeds, oats, spinach, or flax seeds can significantly increase fiber intake.

When you combine several fiber-rich ingredients, a smoothie can easily reach eight to twelve grams of dietary fiber or more.

How To Add Fiber To Smoothies

Use Whole Fruits Instead of Juice

Whole fruits naturally contain dietary fiber and help create a thicker smoothie texture. Bananas, berries, mango, and peaches are all great options. Frozen fruit also works well because it adds creaminess without watering down the smoothie and you don’t need to add ice.

Add Seeds Like Chia or Flax

Chia seeds are one of the easiest ways to boost fiber intake. Just one tablespoon contains around five grams of fiber. They also support gut health and blend seamlessly into smoothies without affecting the flavor much.

Include Oats

Rolled oats are another easy addition that increases both fiber and staying power. They blend smoothly and provide slow-digesting carbohydrates that help keep blood sugar steady. You can even use leftover oatmeal if you want!

Add Healthy Fats

Healthy fats help make smoothies more satisfying. Peanut butter or almond butter adds richness and helps balance the carbohydrates from fruit and a little more protein and fiber.

Include Protein

Protein powder or greek yogurt can turn a fruit smoothie into a more complete meal. Protein works alongside fiber to keep you feeling full longer.

What To Add To Smoothies For Fiber

To make your smoothie feel more like a complete meal, try including three elements: fiber, protein, and healthy fats.

Fiber from fruit, oats, and chia seeds helps support digestion and gut health. Protein from greek yogurt or protein powder helps keep you full. Healthy fats like peanut butter help balance blood sugar and add flavor.

Here are some ingredients that help boost fiber in smoothies:

Chia seeds — about 5 grams of fiber per tablespoon
Raspberries — about 8 grams of fiber per cup
Banana — about 3 grams of fiber per medium banana
Rolled oats — about 4 grams of fiber per half cup
Flax seeds — about 2 grams of fiber per tablespoon
Spinach — about 1 gram per cup plus extra nutrients
Avocado — about 5 grams per half avocado

How To Make A High Fiber Smoothie

1 tablespoon peanut butter
¼ cup rolled oats
½ cup greek yogurt
¾ cup whole milk
Handful of spinach
Optional: 1 scoop protein powder

Instructions

Step 1: Add the liquid base

Start by pouring the whole milk into the blender. Adding the liquid first helps the blender run smoothly.

Step 2: Add creamy ingredients

Add the greek yogurt and peanut butter. These ingredients help create a creamy texture and add both protein and healthy fats.

Step 3: Add fiber-rich ingredients

Add the rolled oats, chia seeds, and frozen banana. These ingredients provide the majority of the dietary fiber in this smoothie recipe.

Pour into a glass and enjoy immediately. If the smoothie is too thick, you can add a splash more whole milk and blend again.

I love to top my smoothies with a little granola for crunch. Serve in a cup or bowl with a spoon.
