Is it Good to Have a Smoothie for Breakfast?

A smoothie loaded with wholesome and nutritious ingredients is perfect for breakfast. That’s the key—you need fiber, protein and healthy fats to satisfy, as well as fill you up for hours.

Starting your day off with a smoothie helps get your digestive system moving, provides your body with clean, usable energy, and when that smoothie is balanced, helps you avoid the mid-morning sugar crash that comes with a carb-heavy breakfast option.

This banana oatmeal smoothie contains banana (shocker!), though the natural sugar from the banana is nicely balanced by the oatmeal and coconut milk to help the body slowly and evenly burn the carbs. #nosugarcrash

Can You Put Oatmeal in a Smoothie?

Yes, you can put oatmeal in a smoothie! You get all the benefits of a bowl of oatmeal, yet in a smoothie form. Oatmeal is loaded with fiber, which boosts the good bacteria in your gut. Whether you need an on-the-go breakfast or you crave a refreshing sippable morning meal, this delicious banana oatmeal smoothie is a great option.

Health Benefits of a Banana Oatmeal Smoothie

All of the wholesome ingredients in this oatmeal smoothie come together for a healthy and nutritious drink that both benefits your digestive system and boosts your heart health. Aside from the irresistible oatmeal cookie flavors, this banana oatmeal smoothie provides 3 key benefits:

Rich in fiber

While we all know fiber is a good thing, do we know if we’re getting enough fiber each day? According to the US Library of Medicine, only 5% of Americans are getting enough fiber each day. That’s why smoothies are such an important addition to your diet! Blended fruits and veggies give you a great fiber boost to aid in digestion, as well as help keep you regular.

One serving of my banana oatmeal smoothie gives you almost 20% of the recommended daily intake of fiber. So blend up and drink up–your body will thank you later.

A banana oatmeal smoothie with healthy fat

I know, fat isn’t always seen as a good thing. Yet hear me out; your body actually needs healthy fat in order to process your food properly. Without fat, the body does a poor job digesting food, converting carbs into energy, absorbing fat soluble nutrients like vitamins A, D, E, and K… which are vitally important. For a creamier smoothie use full-fat coconut milk. For a less creamy smoothie, use a homemade coconut milk, or one you can find in the refrigerated section of your local grocery store.

A naturally low sugar breakfast option

Many quick breakfast options are loaded with extra sugar. While that might make you feel a rush of morning energy, it’s just not sustainable for a busy day. Instead, this banana oatmeal sweet talker with a straw has less than 20 grams of sugar per serving, and balances out that sugar with healthy fat from the coconut milk + fiber from the oatmeal. These ingredients help the body break down the natural sugar, then turn it into usable energy.

Want to help your blood sugar even more? Use a plant-based protein powder, like my homemade protein powder, to give this smoothie an extra 10 grams of protein + 4 grams of healthy fat. This superfood blend helps keep you full longer, as well as provides more energy.

    1. Irish or steel cut oats would work just fine in this smoothie. 🙂

  1. Anybody try this with a little spinach? Seems like the taste wouldn’t change too much.

    1. I think that is a great idea. If you don’t use too much, the green makes them suspicious, they or you will never taste it,

    2. Spinach is really mild and a bit of it would work great here! Give it a blend and let us know what you think.

    1. Our fav is homemade coconut milk, which is super easy to make. Check out How to Make Coconut Milk. Yet, if that’s not an option we use full-fat canned coconut milk too. 🙂

    I’ve made this smoothie almost every day for the past two weeks. I like it to be more like thick milk (versus a smoothie) so I can quickly slurp it down, so I use a non-frozen ripe banana and add ice when blending to make it cold. My toddler godson tried it for his afternoon snack and loved it too. Thanks for a wonderful, simple recipe.

    1. Oh no, sorry about that Kim! These deals are dependent on timing and inventory and Vitamix may be all out of the blender that was listed in Jen’s secret deal. Def sign up for our newsletters if you haven’t already; we often team up with Vitamix to offer special deals on their awesome blenders! 🙂

  3. My new favorite smoothie. I used Almond Milk, which I normally have in the house rather than Coconut. Thinking of adding some cocoa for a chocolate version.

    1. Adding cacao powder for a chocolate version would taste delish!

  4. Can’t wait to try this! Is it okay to have this banana oatmeal smoothie EVERYDAY? Keep rawking on!

    1. Hey Sam! Sure, you can drink the same smoothie every day if you like! But def check out our other awesome smoothie recipes if you decide to mix it up and try some different ones!

    This smoothie is amazing! It was like dessert. I seriously almost licked the blender clean. I followed the recipe, but didn’t get more than 8 ounces out of it, the recipe says 16. Not sure what I did wrong.

    1. So glad you loved it— it’s really, really good! And you didn’t do anything wrong Julia. We had an issue with the serving size with the recipe card. I just went in and fixed that and now it should get you that full 2 cups of goodness. Keep on rawkin’ girl!

    1. After you try it, come back and let us know what you thought, Iris!

    I just made this smoothie for dinner— yep. Was out doiing yard work and the time flew by and I didn’t want to cook something, so I decided to embrace Smoothie Sunday. And this smoothie was AMAZING! I loved how substantial it was (def makes a good meal!). The flavors we’re nice too— great job Jen and the rawkstar team!

    1. That sounds like a great and simple dinner! I’ve eaten oatmeal for dinner so why not an oatmeal smoothie?! 🙂

    2. 5 stars
      This was delicious! I used homemade coconut milk with a scoop of cashew cream.

  7. 5 stars
    Another hit….added a touch of maple syrup and a teaspoon of almond butter….perfection….thank you.

    1. Using canned coconut milk will give your smoothie a creamier texture but either one will work!

    1. I think adding a little bit (maybe 1-2 Tbsp.) of nut butter would taste great in this smoothie! We prefer almond butter over peanut butter but I think any type of nut butter would do. 🙂

  8. It’s always nice to receive a new smoothie recipe, regardless of the day or time (it’s now 5pm here in Greece). This one looks simple and delicious. I have been adding 2 tablespoons of oats to my smoothie every day for the past 5 months in order to help lower my LDL cholesterol level (and with success).
