This easy 90 second keto bread is a life-saver for those moments when you NEED a sandwich and there's no low carb bread in the house. It toasts well and has NO EGGY TASTE!

What do you do when you are on the keto diet and get a craving for cheese toasties? That desire to bite through a crusty sandwich filled with warm, gooey cheese?
I often have homemade low carb 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.
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 90 second keto bread in minutes!
My friends, you will love this bread.
I adapted my low carb English muffins 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 90 second keto bread

1.) Combine egg white, almond flour, psyllium husk powder, baking powder and water in a small 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 "emergency 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 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 ½ tablespoon 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 tablespoon 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 right, 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. I added some garlic powder - but paprika would also give extra flavour.
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!
You could also serve this toast as a quick and easy breakfast sandwich with a fried egg 🙂

Is there any substitute for the physillium husk powder?
Katrin Nürnberger
You can try using ground flaxseed. You may need up to twice as much. Of course, this will change the taste too.

I tried this 90 second b;read last night.I don't have a 5" x 5" dish so I used a smaller soup mug. It turned out very good. I did have to bake a little longer than 90 seconds, it was very wet on the bottom and not baked through. After another 30 second, it was baked. I then sliced it into 2 pieces and put it in the air fryer oven to toast it. I put butter and almond butter on it . It was very satisfying either with butter or butter and almond butter. Thanks for this easy recipe. I will use it again. I made it to eat with a salad and vegetables, but once I tasted it it was gone before I got the rest of my dinner on the table. Thanks for sharing your creations.

Hi Katrin, Tried this the other day for crouton recipe and we loved it - my husband kept sneaking them out of the fridge. Could I make a huge batch and freeze this for toasting at a later date? Many thanks for this and all the other tasty recipes on your website.
Jill
Katrin Nürnberger
Yes, you can definitely freeze this bread.
Jill
Thanks for the quick reply. In the meantime, made your almond bread - fantastic! However, am going to have individual slices of this one to hand as when the almond bread loaf was ready we were sorely tempted to eat the lot
Shelli Fitzpatrick
Quick and easy and tasted good with a fried egg on top. I used flax seed bc I cam't find psyllium husk in my area. It worked fine!
Shelli Fitzpatrick
Next time I will try it with Peanut butter and sugar free jam. I am now in weight maintenace mode after losing 56 lbs with keto.
Katrin Nürnberger
That's amazing - congrats! Glad you're enjoying the bread.
Ruth
I'd love to have a go at this, as I use almond flour/ground almonds alot. I don't have a microwave - do you know a way to do in a conventional oven. Thanks
Katrin Nürnberger
Sure, I would go for 180 C / 250F (electric) or 160C / 320F (fan assisted) and check with a skewer or toothpick after about 12-15 minutes for doneness.
Cathi
All I have is superfine almond flour. Any way I can make it work?
Katrin Nürnberger
Of course. From my experience, you need about 10 percent less flour if your almond flour is super-fine. so just use a tiny bit less and it should be perfect.
Silvia
Can't wait. I'll do it right now.
Karen
Well, I made it and it was a success. I used a whole egg ( too lazy to separate ) and used sparkling water and it looks like in the picture. I'm a very happy person. It is very nice!
Katrin Nürnberger
Glad you liked the bread!
Karen
Hi I have made this a few times now I added mixed herb the last time and it was even lovely worth making
Katrin Nürnberger
That sounds delicious!
Karen
I'm going to give it a go now. Maybe I will have success with it as I have some lovely pumpkin soup with caramel bacon and onion. A piece of toast will go well for lunch.
Anjalee
Can you use whole psyllium husk as that’s all I have at the moment?
Katrin Nürnberger
It should work. You'll have to double the amount and use 1/2 teaspoon.
