About This Recipe
I had to title these zucchini oats the best ever, because seriously you guys, they are the best ever! I do not say that lightly.
I am literally obsessed with these and cannot tell you how many times I have made them now. Besides the fact that these oats are absolutely cozy and delicious, there are so many reasons why I love them and keep going back to them!
These zucchini oats are one of the best volume meals due to both the zucchini and the egg whites really expanding the volume! Each serving size HUGE and I swear it takes me a solid 30 minutes to eat them!
Plus, these oats are packed with fiber and protein to leave you feeling full and satisfied all morning long!
One of the best parts about these oats is that they are super quick and easy to make! If you have a little more time on your hands, I highly recommend trying my Baked Zucchini Oatmeal Bake with Nutella, but when you’re in a time pinch, these are awesome!
These low carb zucchini oats are a big warm bowl of comfort in the morning! But if you love your oats cold, you must try my Strawberry Protein Overnight Oats or Pumpkin Pie Protein Overnight Oats!

Why You’ll Love These Low Carb Zucchini Oats
- They are one of the best volume meals! Each serving size HUGE!
- They will fill you up and can easily be customized!
- You can’t taste the zucchini one bit!
- They are low-calorie, low-carb, low-fat, high protein, again for a HUGE serving here!
- Easy and quick to make!

- Quick oats
- Zucchini
- Egg whites
- Protein powder – My go-to is PEScience protein powder, particularly their peanut butter cookie flavor! It mixes well and tastes amazing. (You can save 10% on PEScience products with my affiliate code LaurenFitFoodie)
- Milk – I used almond milk but any milk of choice works
One of the best parts of these oats is that they are so versatile! You can easily switch up the flavor combos to create a totally different flavor profile. You will never get bored! Here are some of my favorites I’ve tried:
- Peanut Butter Cookie: PEScience Peanut Butter Cookie + butter extract (MY FAVORITE!)
- Strawberry Cheesecake Oats: PEScience Strawberry Cheesecake protein powder + butter extract
- Birthday Cake Oats: PEScience Cake Pop protein powder + cake batter extract
- Strawberries & Cream Oats: PEScience or Vanilla or Strawberry Cheesecake protein powder + strawberry extract
- Banana Nut Bread: PEScience Vanilla + banana and butter extract
- Peanut Butter Chocolate: PEScience Chocolate Peanut Butter Cup + chocolate or butter extract
How To Make
The full printable recipe is below, but let me walk you through the process so you know what to expect when you’re making it!

1. Add zucchini, oats, cinnamon, sweetener, extract, and water.

2. Stir until everything is combined then microwave for one minute.

3. Take out and add the egg whites.

4.Stir in well to prevent any clumps (I like to use a mini whisk for this), then microwave for another minute.

5. Take out, add the protein powder and almond milk and stir in.

6. I like to stir until everything is just about mixed together but not 100%. It adds an extra level of creaminess! Top with nut butter (if desired) and anything else that sounds good and enjoy!
Zucchini Oat Topping Ideas!
Ok you can totally eat these oats on their own and they will be amazing. But they are so much more amazing with some toppings. Have fun with these! Here are some of my favorite ways to top these oats:
- Nut butter – no doubt my favorite topping by far!!! Nothing compares. I love using American Dream Nut Butter and switching up the flavors! (You can save 10% on American Dream Nut Butter products with my affiliate code LaurenFitFoodie).
- Pancake syrup – any will do! It may sound weird, but trust me here! So good.
- Fruit – so many options here. Top with what sounds good! My favorite is Wymann’s frozen Wild Maine Blueberries!
- Black cocoa – sounds weird, but you just need to half mix in some black cocoa powder with the oats and we’re talking major cookies and cream vibes!
- Powdered PB – same idea as the black cocoa, just partially mix the powdered peanut butter in.
- Chocolate chips or candy -Reese’s, butterfinger, M&M’s, peanut butter chips, chocolate chips. AGAIN, THE POSSIBILITIES ARE ENDLESS!

Can I make these oats in advance?
Yes! I used to do this all the time when I was in school and working. Just make like usual, add to a storage container and put in the fridge! You can eat cold or reheat in the microwave. You can also meal prep in bulk to easily grab during the week. They will last stored in the fridge for 5-7 days.
How do I prevent clumps?
If you don’t stir in the egg whites well enough, they can create clumps in the oatmeal. I always use a mini whisk to stir the egg whites in (like this one), so I never have any problems with clumps. But occasionally I will have someone come to me saying they are clumpy. You just have to mix the egg whites in well and there won’t be any!
Do I need to squeeze the excess water out of the zucchini?
No, leave your freshly shredded zucchini undrained! The extra water from the zucchini helps keep these oats moist.
