This easy Keto microwave bread is a life-saver for those moments when you NEED a sandwich and there’s no low carb bread in the house. It comes together in only 90 seconds and toasts well. Gluten free, grain free and NO EGGY TASTE!
Do you get that craving for cheese toasties? That desire to bite through a crusty sandwich filled with warm, gooey cheese?
I often have homemade grain free bread in the house, which I slice and freeze. There’s this low carb bread, my flaxseed bread with coconut flour and this popular almond flour bread. The thing is, we all like them here. So they disappear quickly.
This is what you call a low carb bread emergency!
So, what do you do when you want to sink your teeth into a comforting cheese toastie without having to bake a whole loaf of bread? Or if you just want ONE slice of crunchy, warm toast spread with melting butter and sugar free jam for breakfast?
Thankfully, if you have a microwave you can solve your dilemma double-quick. You can make the most delicious “emergency bread” in minutes!
I love these microwave low carb English muffins from my blog, which are wonderfully rich and buttery. I adapted them to create a Keto mug bread recipe using almond flour that tastes more like a whole-wheat toast.
I omitted the butter and used water instead, to make the recipe lighter. I also added psyllium husk powder for a better texture. Are you ready?
How to make Keto microwave bread – step by step:
1.) Combine egg white, almond flour, psyllium husk powder, baking powder and water in a bowl.
Note – By the time I had shot this picture, the baking powder had begun to fizz up (which is a good sign as it means it’s fresh!). It might look like a lot, but it is the same amount as the psyllium powder.
2.) Mix with a fork…
3.) …and fill the dough into a well-greased microwavable container. Spread well to ensure there are no large air bubbles.
I used melted butter to grease mine, but you could use coconut oil, avocado oil or even olive oil.
4.) After microwaving on high for 90 seconds, your single serving of “toast” is done. As you can see, the bread shrinks a bit and comes off the edges so it’s easy to release from the container.
5.) At this point, your almond flour 90 second bread is soft and looks a bit pale. Don’t let this discourage you! Before we proceed, check out the other side:
6.) See? It has a fluffy, light texture. And once you toast, grill or pan-fry your Keto toast, it looks pretty, too!
Tips and tricks to make the perfect Keto microwave bread:
This really is a super-easy recipe, and there are several variations that all taste equally great. It’s simply how you prefer it:
SHAPE
I used a 5 x 5 inch glass dish, which produced 1 large slice of Keto toast. I made another portion using a 4 x 3 tupperware container, which I then sliced in two. You could even use a mug and cut your bread into 3 smaller, round slices.
ALMOND FLOUR
I love baking with almond flour and ground almonds, but some people cannot tolerate tree nuts. If you prefer to try this recipe with coconut flour, use 1 1/2 tbsp instead of the 3 tbsp. Coconut flour absorbs more liquid than almond flour. Fo the same reason, I also recommend to increase the amount of water to 1 tbsp.
It’s worth mentioning that I used ground almonds for this recipe, which is what we call regular almond flour here in the UK. If you want to use SUPER FINE almond flour such as Bob’s Red Mill, you should definitely increase the amount of water to 1 tbsp as well.
EGG
I decided to go for egg white only as the “eggy” taste some people dislike is in the egg yolks. I personally don’t mind it and you CAN make this recipe with a whole egg if you prefer. This way you get a healthy golden colour even before toasting.
PSYLLIUM
The psyllium husk powder gives the bread a stronger texture, similar to whole-wheat bread. You can use flaxseed if you don’t have psyllium or a pinch of xanthan gum. In my many test runs to get the recipe just the way I like it best (no problem when it’s as quick as this one), I have also made a version omitting the psyllium altogether. As you can see, this bread is quite versatile!
To satisfy my cheese toastie craving, I gently fried the bread in butter over a low heat. Almond flour burns quicker than regular wheat flour. Take your time and keep the lid on so the cheese can melt without the bread burning!

Clare Barber says
I see a lot of recipes calling for psyllium husk. Where do I buy it please? Also seen some posts saying some versions can make your food turn purple? Which brand do you use?
Katrin Nürnberger says
Hi Clare, I have used BonPom and Green Origins without problems. I buy them from Ocado (so Waitrose will probably have them too) or Planet Organic, my local organic store. I haven’t quite gotten to the bottom of why stuff turns purple for some people. It was always assumed it was to do with the brand, but recently I heard that it’s to do with a reaction of psyllium to aluminium in baking powder. I’ve never had baking powder with aluminium in it, but if I ever discover one I must do a test.
Bonnie Knight says
I saw somewhere on another post that you can use a bread slice shaped container like you can put a sandwich in. Once the “dough” is ready it was microwaved.Would this work for your recipe? How long should I microwave it?
Best,
Bonnie
Katrin says
This is exactly what I did in this post. You can see in the images the pyrex container I used. It happens to be a sandwich-sized square shape. I microwaved it for 90 seconds.
Linda says
Woooohoooo bread… Keto style anyway. It was soooo good. Added salt though and used a whole egg, turned out perfect. Can these slices be frozen?
Katrin says
Yes, I think that should be no problem. But if you want to freeze a whole batch I’d probably make a “real” low carb bread and slice it – much quicker! Have you tried this almond flour bread?
rosie bevington says
Just made my first sugarfreelondoner recipe – and I loved this quick microwave bread. I also made it into a delicious fried cheese and tomato toastie! Even my dog didn’t get a look in as he waited patiently. As a recently diagnosed diabetic I’ve been eating too many carbs for too long, so I’am looking forward to trying other recipes. Thank you
Katrin says
I’m so glad you like the recipe Rosie! I hope you’ll try out more of my bread recipes, they are a good replacement for wheat bread. I used to miss bread so much until I started baking it myself. Just type “bread” into the recipe search box at the top of each page and you’ll be able to check them all out.
Olga says
Thanks for the recipe!
Could I bake it instead microwave it?
And could I use recipe to make a loaf by increasing the amount?
Katrin says
Hi Olga, you could bake it at about 180 Celsius, probably for about 12 minutes. However, it’s not really worth it to heat an oven to bake one slice of toast. I’d recommend my almond flour bread instead!
Bridget says
Just made this bread – super easy and super tasty – than you!! Used milk instead of water and got amazing result.
Katrin says
Good to know! Thanks for letting us know 🙂
Maria says
OMG, this was so good! Thank you very much!
Katrin says
Glad you liked it!
Deb says
Hi Katrin,
I just wanted to say thank you for creating this site. I have only been Keto for 5 wks but know I have found my way of eating for life. So finding your alternative recipes is amazing. I don’t feel like I am giving anything up, just gaining health.
Bread of course is not allowed, so when I saw this recipe I was jumping with joy. I loved it, your a star ⭐️ I have made the granola and the fudge cake and I can’t wait to try more recipes.
Katrin says
That’s so good to hear! I’m glad you like the recipes. Let me know which one you try next, I’d love to hear how it went and what you think of it!
Jewels says
Have not made the recipe yet but it’s happening later today — thank you!
Pound stores/Dollar stores sometimes have small glass containers with plastic lids
for packing in lunches, also look for small casserole dishes (Corning Ware in the US)
it doesn’t matter how deep the sides are. You could also make a mold out of
a paper plate and rubber band, and line with greased parchment in a bread emergency!
Katrin says
OMG I love your ingenuity!! Thanks for sharing 😉
Clarisse says
This one turned out really well. So satisfying after 3 months of no bread! Thanks for the recipe❤️
Gretchen says
Is there a way to make a bigger batch of this? It is SO good! Very close to regular bread consistency and taste and doesn’t feel heavy like most keto breads.
Katrin says
I guess you could try microwaving more than one batch at once and increase the time in the microwave accordingly. I’m sure it would work, you’d have to test and see how much longer you’d need.
Roze says
Why can’t you use super fine almond flour?
Katrin says
You can, but I have not tried this myself so I cannot guarantee it will be amazing – though it might be. The consistency will be different. Super-fine absorbs more liquid than regular almond flour. If you have it in the house, give it a go and let use know how it comes out?
Penny O says
Thank u for the recipe!! I’ll check in after I make it.
Luci Sosnowski says
Thank you!!! I used ground flax seed instead of psyllium as it’s what I had in the house. I just got back from a week in Florida for my granddaughter’s wedding and completely blew my keto program, eating the way I used to, and gaining 4 pounds back from the 35 I’ve lost in the last 18 months. With no fresh groceries in the house and determined to get back to my program, I searched the cupboards and found albacore tuna in water, one of my favorite “go to’s” on salads and in dips. Again, not much in the fridge. I made to large slices of the bread with frozen egg whites left over from Hollandaise sauce and toasted them. I melted some butter in a fry pan, added a little flax seed flour and almond flour to act as a thickener, added the tuna with a little bit of still fresh heavy cream, garlic salt, pepper and parsley and served the creamed tuna on toast. I would normally have put frozen peas in the mix but used frozen chopped broccoli instead, again what was in the house. Creamed tuna on toast was always an easy quick meal in the pre-keto days and the new version did not disappoint.
Katrin says
That sounds delicious. Amazing what you can make with the last bits and pieces you have in the house, right? It’s like “there’s nothing to eat!” and 10 minutes later you’re enjoying something rather amazing. And good to know that flax works in place of the psyllium!
Nicole M Foster says
This turned out really well! I have only eaten it as toast so far but can’t wait to make a grilled cheese (or cheese toastie?) with it!
Katrin says
Glad you liked it Nicole!
Nina says
OMG. THIS is what I’ve been craving for years since starting keto. A cheese toastie. Just made one. Delicious. THANK YOU!
Katrin says
You can’t beat a good cheese toastie to lift the mood 😉
betty says
Super simple and yummy. Made one with almond flour and one with coconut flour. Liked the almond flour one best. Thanks,
Katrin says
So glad you liked the bread Betty! Thank you for taking the time to comment 🙂
Chowder says
Thank you for sharing this.. either way (almond flour or coconut flour) turned out great. This is my go-to keto bread, so simple and easy to make.
Fiona Weston says
What if you don’t have a microwave? Could you do this in an oven?
Katrin says
Yes, I would try 175 Celsius / 350 Fahrenheit for about 12 minutes. This way you can brown it at the same time.
Heather H. says
I’d love a link to where you found a 5×5 glass dish! I can’t seem to find one anywhere… Thank you!
Katrin says
The one I used is from Ikea 🙂 It’s this one https://amzn.to/2EYnvVQ
