These Breakfast Protein Cauliflower Oats are super easy to make, nutritious, and macro-friendly. Perfect for adding your favorite toppings!
About This Recipe
I’m not always a big breakfast eater. But sometimes NOTHING hits the spot like a bowl of warm oatmeal. But if I’m going for oats, I love to find ways to bulk it up and get MORE bang for my macro-buck. These protein cauliflower oats are the ticket.
This is a quick, microwave recipe, easy peasy. Adding steamed cauliflower helps load them up with vitamins and minerals not found in the oats! (Vitamin C, B6, and magnesium, to name a few!) And of course, it makes your bowl of oats so much bigger while adding just a few carbs. WIN.

Ingredients and Substitutions
- Steamed cauliflower rice: I like to buy a steamable frozen bag of riced cauliflower and microwave it right in the bag with the corner snipped until nice and soft.
- Old-fashioned oats: Use gluten-free if needed.
- Water: Feel free to adjust the amount based on how liquidy you like your oats.
- Cinnamon: Adds the perfect hint of spice.
- Sweetener: I prefer to use a liquid sweetener like liquid stevia or monk fruit for these overnight oats. I personally just like how the liquid blends in, but any type of sweetener will work! You can also use honey, maple syrup, agave, etc.
- Pinch of salt: Helps to balance the flavors.
- Liquid egg whites: A great way to add protein!
- Milk: I used unsweetened SILK cashew milk, but any milk of your choice works.
- Protein powder: Grab your favorite protein powder. I like the Clean Simple Eats Snickerdoodle or Maple Donut for these oats. Or for a dairy-free option, I love Active Stacks! Use LILLIE for a discount.
- Toppings: I like to top mine with fresh diced peaches, blueberries, toasted almonds, a little creamer (I LOVE the Califia Farms almond milk creamer options, all flavors are good!), and a drizzle of sugar-free syrup (I like Birch Benders Magic Syrup since it’s sweetened naturally with monk fruit and stevia rather than sucralose like lots are).

How To Make
- You’ll start by steaming your cauliflower according to package directions.
- Add oats, water, cinnamon, stevia, and salt to a bowl and microwave for 60 seconds. Give it a good stir, add the egg whites and steamed cauliflower, and then microwave on high for another 60 seconds. Take it out, give it another stir and pop it back in for another 30-60 seconds until liquid is all absorbed. Don’t worry, the egg whites cook quick and easily in there. (But also liquid egg whites are safe to consume raw if you’re worried!)
- Whisk or shake cashew milk with protein powder and pour it over the oats. Add extra stevia if needed. If you have a sugar free syrup that you love, a drizzle of that can be great too.

Serving Suggestions
Top with whatever oatmeal toppings you love! I’ve got the macros below for the bowl without toppings, or with a few of my favorites, diced peaches, blueberries, toasted almonds, and some Almond milk creamer. For the protein powder, I like the Clean Simple Eats Snickerdoodle or Maple Donut (use code LILLIE for a discount) for this. But as I said, use your favorite!

Can you leave out the egg whites or can you substitute with something else?
I made this with only 30g of cauliflower to try it out and I used chocolate protein. It was really good! And I coudnt taste the cauliflower. I will make it with 70g of cauliflower from now on. If you like overnight oats dont be intimidated by they cauliflower.
This is good but I like my overnight oats more thick and this was too liquidy. But the flavor overall was great and you can’t tasted the cauliflower! I’ll just adjust my liquids next time. Lillie’s recipes are the best!!
Delicious and filling, would never have guessed this has cauliflower
