Bread continues to be one of the biggest struggles for those who are considering cutting the carbs. I get it, even with amazing keto bread recipes, cutting the bread can still feel limiting. 

But that's why it's important to have options.  

Even though there won't be a bread that tastes just like the wheaty, gluten-y, flour-y loaf that you might be used to, it can be so satisfying to find healthier options that don't make you feel like you're missing out.

What do I need to make Keto Cauliflower Buns?

All you'll need is:

  • Almond Flour: This helps to hold the bun together. I'm sure coconut flour would be a great substitute, though I haven't tried it myself. If you do go for it, just remember that coconut flour is very absorbent and you'll always need less 
  • Cauliflower: A Steamer Bag is totally fine, it'll even help cut down on cook time
  • Mozzarella Cheese
  • Cheddar Cheese
  • Egg

The possibilities are endless with these cauliflower buns. From breakfast sandwiches, to hamburger buns, to grilled cheese sandwiches this is the missing piece you've been looking for.

Do these buns have a heavy cauliflower taste?

I think the cauliflower taste is pretty mild, but if you really don't care for cauliflower and still want to give these a try, I'd suggest experimenting with stronger tasting cheeses to further mask the taste of the cauliflower. You can also use seasonings in the bun mixture, or top your sandwich with stronger sauces like sriracha to add flavor and spice!

Keto Cauliflower Buns Nutrition

I've only calculated the nutrition for the buns themselves because there are so many things you can fill them with, all with varying nutrition. For two thin buns (a top and bottom) you're looking at:

Calories: 151 Calories
Total Carbs:
Net Carbs:

Don't fret that the protein is higher than the fat. Remember, everyone's macronutrient needs are different. Also, you won't be eating these buns by themselves, and what you fill them with can easily round out the macros.

And here's a breakdown for all of the ingredients I used.

And here's how I made it.

I am totally trying this recipe! I have always failed when attempting to make 90 second bread and I am not the greatest fan of almond flour, so would probably use coconut flour and use slightly less. Thank you for the inspiration - I can finally have a Keto sandwich! :) Sim x

These sound pretty good...I want to try them. Question? Are they storable? If so, how and for how long?
