90 Second Keto Bread is one of those recipes that everyone on the ketogenic diet needs in their life if they miss bread. Quick and easy to make, you’ll love having a low carb bread option at your fingertips. This is seriously the best keto bread recipe.
90 SECOND KETO BREAD
A hamburger bun or slice of bread might be what many of us dream about those first few weeks of eating a keto diet. I think we all start looking for some kind of substitute to satisfy our bread cravings. I know I tried a host of different recipes, which left me feeling disappointed mostly.
Then, I started hearing about 90-Second Keto Bread. If you’ve ever tasted it straight out of the microwave, you may understand why I think it is a lifeless, dull, flimsy eggy bread. I am just not that desperate for bread if I have to eat it like that.
I love tweaking recipes and thought there has to be a solution that would bring this keto bread to life. The key to a delicious 90-second keto bread recipe is browning it in a skillet before serving with a little butter to make it crisp.
WHAT IS 90-SECOND KETO BREAD?
It is simply a single portion of a keto-friendly bread cooked in the microwave for 90 seconds.
HOW MANY CARBS IN 90-SECOND BREAD?
This particular recipe has 1g net carbs per serving. This will vary depending on the serving size.
INGREDIENTS FOR 90-SECOND KETO BREAD:
- Egg (you can also use an egg white if you are particularly sensitive to foods tasting eggy)
- coconut flour
- butter
- sour cream
- baking powder
- cheese
- pinch of salt
After you mix up all the ingredients, it will look a little lumpy like this in the picture above. Now, you simply microwave for 90 seconds.
This is sad, lifeless 90-Second Keto Bread straight out of the microwave. You don’t want to eat it like this as it will taste spongey and eggy. The next steps are the most important in the process of making the best keto bread recipe.
How to reheat and cut your low carb bread
I tend to make my 90-Second Keto bread rather thin in a ramekin instead of a mug. Otherwise, it is just too thick for me. You’ll need a serrated bread knife to cut the bread in half horizontally.
Melt butter in a skillet and sear bread on both sides until it’s crispy. I use an 8″ skillet.
There are so many ways to enjoy this 90 second bread keto recipe.

90-SECOND KETO BREAD WITH BACON AND CHEESE
Crispy thick-cut bacon and a variety of cheeses make this bacon and cheese sandwich simply divine.

KETO FRENCH DIP SANDWICH
Last night I made Keto Pot Roast and remembered a recipe at lunch today where you serve pot roast on bread with melted cheese. As I was making the bread, I decided to change up some of the ingredients in hopes of making it even better. I can say that it was a total success. You do still need to crisp it up in a skillet or toaster oven for sure, but the flavor is so much better with the changes I made.

Cat says
I have an allergy to eggs do you think this bread could be made with substituting chia seeds for the eggs?
Kasey says
I’m not sure I don’t have any experience cooking with chia seeds. Let me know if it works. Thanks.
Beth Cassidy says
What size/type bowl did you use? I couldn’t tell from the pic since it was taken from the top. Thanks!
Kasey says
Hmmm….I’ve used several different containers. I think they were maybe 6inches?
Mel says
I made a turkey and pepperjack grilled cheese with this today but instead of frying in a skillet with butter, I added mayo to the outside of each slice and fried it. It was absolutely delicious!! Thanks for posting this recipe. I will definitely be making again.
Kasey says
OH, wow! That is definitely a new way to make it. Thanks for sharing.
Lynn B. says
This was awesome, thank you!!
Kasey says
Sure! Glad you loved it!
Lisa says
Best keto recipe I’ve tried yet!!! Can’t wait to make it again!
Kasey says
I’m so glad you loved it!
Tammy Parker says
I made it today ! I used the 3 tablespoons of almond flour and I put cut up jalapenos and I put pepper jack cheese( I like spice )
I used plain yogurt instead of sour cream and a tiny bit of almond Milk.
I used coconut oil and GHEE ( clarified butter) instead of regular butterand a pinch of salt.
It was very fluffy. I cut it in half and toasted in my toaster oven afterwards to crisp it up.
When I took it out of toaster oven I put some pepper jack cheese and bacon in the middle as a sandwich.
It was yummy 🙂 I had it with my soup today !! 🙂
Kasey says
That sounds absolutely fantastic!
Michele says
Kasey, I have trouble cutting the bread in half. Do you think it would be easier if I put it in the fridge for a while?
Kasey says
Do you have a serrated bread knife? I’ve never had any trouble so I haven’t tried cooling it first.
Takiyah says
Perfect. I had no sour cream, so used 1 tbsp of cream cheese instead. I also used mozzarella instead of cheddar because it has a mild flavor and was afraid the cheddar would make the bread taste too cheesy (I had shredded mozzarella, so I chopped it very finely on a cutting board). I actually forgot to add in the baking powder! Despite that, the bread came out perfect. I toasted it first and then placed it in a pan and browned it on each side for a few seconds without butter. Definitely making this again! It was great. Didn’t taste eggy at all and the consistency was pretty good. I’d love to find a way to make it hamburger friendly. Thanks for sharing! ?
Kasey says
So glad you enjoyed it. Sounds like your tweaks turned out perfectly! Thank you for commenting.
Teresa says
Can you use mozzarella instead of cheddar and cream cheese instead of sour cream. Don’t care for sour cream taste
Kasey says
I haven’t tested that exact combination so I can’t say for sure, but I think it would be fine. I hate sour cream, but you really can’t taste it.
elisabeth says
Absolutely LOVE this bread recipe!! I’ve been able to enjoy grilled cheese sandwiches without all the guilt! Thanks so much.
Kasey says
Awesome! So glad you enjoyed it!
Aimee says
Thanks for the recipe. In the ingredient list, you say 1 1/4 tablespoon butter. In the instructions, 1 tablespoon is used to fry the bread to crisp it up. Is that an ADDITIONAL tablespoon of butter? Or is only 1/4 tbsp used in the bread batter in the mug?
Thanks!
Kasey says
1 1/4 is used in the bread. The additional tablespoon is not included in nutritional info as some of it evaporates and stays in the pan.
Michele says
Kasey, I love this bread1 Not only is it tasty, it’s versatile. I have used mozzarella cheese instead of cheddar; cottage cheese instead of sour cream; and I have just tried using flax seed meal instead of coconut flour. It came out perfect! I do have serrated knife, but my problem was I can’t cut straight. Today I did it slowly and the slices came out much better. Thanks for the recipe and for letting me ramble on.
Kasey says
Perfect!I’m so glad you enjoy it. Tweaking recipes is so fun! It’s okay if it isn’t straight. 🙂
Babs Harrell says
Michelle,
Was the ratio of Flaxseed the same as the coconut flour? We have a nut allergy and a coconut allergy so I was looking for something else to substitute. 🙂
Amy says
This was so much better than expected. I just started Keto and as a recovering carb addict, I
miss bread. This is the perfect solution! Cheap, easy and delicious!!!
Kasey says
Awesome! I’m glad you loved it!
Wendy says
You had mentioned in your original post that you used an air fryer. I’ve been thinking about this purchase, but was wondering what kind you use. There are so many to choose from.
Kasey says
I have a Cuisinart Air Fryer/Toaster Oven combo since it takes the place of 2 appliances. I love it! This is the one I have. https://amzn.to/2oH4TRA
Tanaya says
I just pre made 90 sec bread…how long can I store it in the fridge??
Kasey says
I’m not sure as I always eat it immediately; however, I wouldn’t think it would be different than any other kind of food. I don’t eat leftovers past 3 or 4 days.
Mica Ike says
Just made the bread using almond flour (3 tablespoons) and I can’t believe it’s not butter (ran out of the real stuff). IT’S AMAZING!!!!
Kasey says
So glad you loved it.
Shirl says
I tried this recipe today. Didn’t have sour cream so I replaced it with greek yoghurt. Can’t believe how easy it was to make this and it tasted really yummy with cheesey egg and bacon!
Kasey says
Perfect! SOunds delish!
Valeri says
First Keto bread I can stomach!! So good!! You have saved my sandwich life!!! ?
Kasey says
Glad you enjoyed it.:)
Sandra Dee says
Thank you for a great bread recipe. I made a grilled cheese with bacon and it was yummy!
Kasey says
So glad you enjoyed it! That sounds fabulous.
Isha says
I don’t have a microwave. Can this be done in the oven?
Kasey says
Sure!
Debbie Brewer says
Omg! This is awesome! Do you know how long it will keep if I make a few & refrigerate? I’ll be traveling & would love to bring some.
Kasey says
Since there are no preservatives I’m not sure how long it will keep. I would keep in the fridge to make it last longer. I would say maybe a couple of days. You can also make a loaf and freeze it and pull out a couple of pieces at a time. Here is a link to the loaf.

Julie says
I made this tonight because I passed on cornbread with dinner and was really feeling sorry for myself for not being able to have cornbread. ?
When grilling it, it still smelled a bit eggy, but didn’t really taste like it. However the smell made me think of French Toast. ? so I sprinkled some cinnamon on it, drizzled on some sugar free syrup and presto!!! It was great as French toast!
Kasey says
Awesome! Glad you enjoyed!!
Lori says
I don’t have a microwave… does this mean I can’t make this??
Kasey says
You can bake it. I’d try 350 degrees and watch until it is done.
Steph says
The main thing is: coconut flour has a distinct coconutty flavor. Does this bread still taste like that? I like what coconut flour can do but almond flour doesn’t get that “taste.” how is this bread?
Kasey says
I am used to coconut flour so it doesn’t bother me. Also, my oldest daughter is allergic to almonds so I have never tried almond flour. If you are particularly sensitive to coconut flavor you may want to look for a different recipe that uses almond flour.
Beth says
Oh my goodness I can eat this one! It’s really really good… Best recipe I’ve had yet! The only thing I did differently was substitute the sour cream with Greek yogurt because I already had it in the fridge. Excellent !
Kasey says
Awesome! So glad you love it!
