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 Protein Smoothie Boost, 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.

    • Simple Green Smoothies says:

      Way to rawk a healthy breakfast, Danyell!

  7. Dr. D says:

    Loved this smoothie, but what about soaking the oats beforehand? The same questions goes for you oat milk recipe, which I am dying to try.

    Dr. D.

    • Simple Green Smoothies says:

      If you’re up for it, soaking the oats for several hours before blending in this smoothie (or making oat milk) is a great idea! It reduces the phytic acid and the starchiness of the oats, allowing for better absorption of the nutrients in them.

  8. Erin says:

    I added raspberries in this when I made it, and it was SO good! A filling breakfast recipe.

  9. Annie says:

    Loved this and it’s so versatile! I tried adding a little kale and some frozen blueberries. The berries seemed to hide the kale color and flavor and it tasted kind of like a cross between blueberry muffins and banana bread

    • Annie says:

      Oh! And pulsing the oats a few times in the blender before adding everything else made it turn out more smooth for me:)

    • Simple Green Smoothies says:

      Love the upgrades Annie! Rawk on!

  10. Martha says:

    I am wondering about the use of coconut milk or coconut oil.. I have heard many people say there is too much fat in it. What say you Jen?

    • Simple Green Smoothies says:

      We are def all about healthy fats here at SGS! We know that they help our bodies absorb vitamins, help our skin glow and stay hydrated, help to keep us from overeating and even help our brain work correctly. We’d suggest reading more about it so you know for sure what’s best for your body. You can start with our article :: Healthy Fats – What Are They + How to Use Them which contains links to additional research from places like the National Institutes of Health.

  11. Cheryl Turner says:

    I did not have coconut milk and used almond milk.
    It was absolutely delicious ! Love this recipe because you do not need a lot of different ingredients and it is simple and easy to make.

    • Simple Green Smoothies says:

      Almond milk is a rawkin swap! Thanks for giving it a blend!

  12. Yelena says:

    This was very good! Thank you for sharing your recipes! I didn’t have any coconut milk, I used oat milk instead, turned out very creamy and delicious!

  13. Anna says:

    I used full fat coconut for a creamier smoothie, but the coconut flavor and texture overpowered the oats and bananas :/ I would recommend using a lighter coconut milk. I’m planning on trying it again and hope for a better outcome!

    • Simple Green Smoothies says:

      Thanks for the feedback Anna! Def let us know what you think with your next blend!

  14. Monica says:

    Would quick oats work?

    • Simple Green Smoothies says:

      Hi Monica! Quick oats would work just fine here.

  15. Mike says:

    Has anybody tried this with regular cow’s milk instead of coconut milk? If so, how’d it end up?

    • Simple Green Smoothies says:

      We think it’d be just as good with cow’s milk, yet haven’t tried that option out. Anyone else? If you give it a blend with the moo let us know! 🙂

    • Mike says:

      Update: I tried it with 1% cow’s milk, and it turned out delicious! Reminded me of an oatmeal cookie.

    • Simple Green Smoothies says:

      Thanks so much for the update Mike!! Good to know. Heading for my blender now…

    • TJ says:

      I tried it with cow’s skim milk and omitted the syrup. It was sweet and delicious.

  16. Carol says:

    Can you use Irish Oatmeal instead of rolled oats

    • Simple Green Smoothies says:

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

  17. RM says:

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

    • sharon says:

      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,

    • Simple Green Smoothies says:

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

  18. Kt says:

    Do you use canned coconut milk?

    • Simple Green Smoothies says:

      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. 🙂

  19. Nicole P says:

    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.

  20. Kim says:

    vitamix link to deal doesn’t work

    • SGS Rawkstar Jess says:

      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! 🙂

  21. Rachel says:

    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.

    • SGS Rawkstar Jess says:

      Adding cacao powder for a chocolate version would taste delish!

  22. Sam says:

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

    • SGS Rawkstar Jess says:

      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!

  23. Julia says:

    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.

    • Jen Hansard says:

      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!

  24. Iris says:

    Can’t wait to try this tomorrow morning

    • SGS Rawkstar Jess says:

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

  25. Dani Mitchell says:

    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!

    • SGS Rawkstar Jess says:

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

    • Olivia says:

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

  26. Dieta says:

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

  27. Mary says:

    Do you use canned coconut milk or boxed?

  28. Olivia says:

    This looks great! What’s your take on using peanut butter with this recipe?

    • SGS Rawkstar Jess says:

      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. 🙂

  29. Marianne says:

    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).

  30. Erin says:

    Thanks for a fun smoothie recipe! I can’t wait to give this a try today.
