This high fiber fruit smoothie is my go-to breakfast when I need something quick and seriously nourishing to start the day. It is loaded with fiber and protein yet manages to taste like a fruity treat, and it keeps me full all morning.

When I began my journey to eat more fiber, I started playing around with different add-ins. This smoothie quickly became a staple, and now I crave its tart berry flavor and thick shake-like texture on busy mornings.

What You'll Need

  • Frozen mixed berries: These deliver a tangy burst of flavor and tons of antioxidants. Look for blends with mostly blackberries blueberries and raspberries for the best texture
  • Ripe banana: Gives sweetness and body. Choose one with plenty of brown spots for the best flavor
  • Chia seeds: They are the secret boost for fiber and a little healthy fat. Make sure they are fresh and not too old to maximize the nutritional punch
  • Rolled oats: This is where the fiber magic comes from. Use regular old-fashioned oats for the best texture and gently nutty flavor
  • Greek yogurt: Offers creaminess plus an extra dose of protein. Choose whole milk or 2 percent for a thicker smoothie
  • Water or milk: Lets you control the consistency—milk gives a richer flavor while water keeps it lighter
  • Vanilla protein powder: This is totally optional but it is great if you want to bump up the satiety and sweetness. Use a high quality brand with simple ingredients for the best taste

How to Make It Happen

Get Prepped:
Measure and gather all the ingredients so everything is ready to go. If you like your smoothie extra cold you can freeze the banana in advance
Load the Blender:
Add the frozen mixed berries banana half chia seeds rolled oats Greek yogurt and your choice of liquid into your blender. If you are using protein powder drop that in now
Blend Until Smooth:
Start blending on a high setting for 30 to 45 seconds. You want the oats fully broken down and the chia seeds incorporated for the smoothest drink. Scrape down the sides if anything sticks
Adjust the Consistency:
If your smoothie is too thick splash in a little more water or milk. If you need it sweeter add the other half of the banana and blend again. Taste and keep tweaking until it is just right
Pour and Enjoy:
Serve immediately in your favorite glass. This smoothie will thicken if it sits too long so drink up while it is at its creamy best

My absolute favorite part is the tartness from the berry blend. Every time I make this smoothie my kitchen smells like summertime and it makes me think of the first time my son agreed to try chia seeds because he could not even see them in the glass

Keeping It Fresh

This smoothie is at its best right after blending. If you must make it ahead keep it in a tightly sealed mason jar in the fridge for a few hours but give it a good shake before sipping as chia seeds cause it to thicken. Stir in a little extra water or milk as needed. I never have leftovers but if you do it is delicious poured into popsicle molds for a frozen snack

Smart Swaps and Substitutions

No banana Swap in half an avocado or a scoop of nut butter to maintain creaminess. No Greek yogurt Use a dairy free yogurt or simply add more oats and a splash of milk of your choice for texture. Not a berry fan Try frozen cherries peaches or even mango in place of the berries. Just skip pineapple if you want to keep the fiber content high

Perfect Pairings

A slice of hearty whole grain toast with almond butter makes this breakfast a complete meal. Serve as a snack after a workout alongside a handful of walnuts for added protein. Top with a little extra granola or seeds for crunch if you want a smoothie bowl vibe
