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. My microwave bread toasts well and has no eggy taste. It contains just 4 ingredients.

I love baking keto bread, which I slice and freeze. The thing is, we all like bread here. And we always run out of it.
So, what to do when you want just ONE slice of crunchy, warm toast without having to bake an entire loaf?
Thankfully, with a microwave you can solve this dilemma quickly. Simply make this 90 second keto bread.
Even with mixing the ingredients, you'll be able to have this bread ready in 3 minutes.

🌟 Why You'll Love This Recipe
- Fluffy, soft texture - just like white toast
- 4 ingredients
- No eggy flavor
- Naturally gluten-free and dairy-free
- Keto friendly - only 1.6g net carbs
- Ready from scratch in 3 minutes
Ingredients

Here are the ingredients you'll need:
- Egg white - Using only the egg white and not the yolk means there is no eggy taste.
- Almond flour - I used regular almond flour. If you want to use SUPER FINE almond flour such as Bob's Red Mill, increase the amount of water to 1 tablespoon.
- Psyllium husk powder - Gives the bread a stronger texture, similar to whole-wheat bread. You can use flaxseed instead, or a pinch of xanthan gum.
- Baking powder
- Water - or use almond milk
See the recipe card for full information on ingredients and quantities.
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.
Instructions
It's so simple to make keto bread in the microwave. Here are the basic steps.
For detailed instructions, scroll down to the recipe card.

Step 1: Combine all ingredients in a small bowl and mix with a fork.
Step 2: 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.

Step 3: After microwaving on high for 90 seconds, your single serving of "emergency toast" is done.
The bread shrinks a bit and comes off the edges so it's easy to release from the container.

At this point, the bread is soft and looks a bit pale. Don't let this discourage you.
Image 4 and 5 show the bread from both sides. As you can see, it has a fluffy, light texture.
And once you toast, grill or pan-fry your Keto toast, it looks pretty, too!
Katrin's Top Tips
#1 Timing: I have made this recipe with several microwaves over the years. 90 seconds always seems to be the perfect cook time.
However, in your microwave, it may need less or more. Check after 75 seconds and see if it is cooked. Just don't overcook it or the bread will dry out.
#2 Container: 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 inch tupperware container, which I then sliced in two.
You could even use a mug and cut your bread into 3 smaller, round slices.
Variations
For a flavor lift, add a pinch of salt to the batter.
For a savoury version, add a pinch of garlic powder or paprika. Or, add 1 teaspoon of grated parmesan cheese or nutritional yeast.
Recipe FAQs
If you prefer to try this recipe with coconut flour, use 1 ½ tablespoon instead of the 3 tablespoons almond flour. Coconut flour absorbs more liquid than almond flour. I also recommend to increase the amount of water to 1 tablespoon.
Yes, you CAN make this recipe with a whole egg. This way you get a healthy golden colour even before toasting. The bread will taste a little eggy this way. I personally don't mind it, but some people don't like it.
Yes. In my many test runs to get the recipe just right, I have also made a version omitting the psyllium. As you can see, this bread is quite versatile!
I make a keto mayonnaise.
Yes. Bake it at 180C or 350F for around 12 minutes.

Serving Suggestion
I love 90 second keto bread toasted and then spread with butter and sugar free strawberry jam.
But, it tastes great with any topping, from sweet to savoury.
Often, I make grilled cheese with it. For this, I gently fry the bread in butter over a low heat. I add 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 can also use it to make my 10 minute sugar free French toast.
Storage
Store the bread in an airtight container in the fridge for up 3 days. You can also freeze it for up to 3 months. Re-heat it in the toaster.

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.
Christal
I need nut free keto flour recipes PLEASE&THANK YOU❤️
Katrin Nürnberger
Hi Christal, you can search for "coconut flour" in my recipe search bar, which is at the top of each page. You can also replace most almond flour recipes with either 1/3 the amount in coconut flour or replace it 1:1 with a 50/50% blend of sunflower and sesame seed flour.

Best 90 second recipe I’ve ever tasted. My grilled cheese for lunch was fantastic!
EL
These are amazing! Made with whole of egg as well as just the white. Using the whole egg made it like an omelette but much more of a bread texture. I tried in the oven and it didn’t come out that great although tasted good. Just a bit dry. My favourite method is cooking in frying pan with butter. Made one this morning with sweetener and cinnamon lovely! Just like Sweet French toast. Used ground flax, because don’t have any psyllium, and it held together really well with nice texture. One of these fills me up for quite a few hours much more so than wheat bread. Thanks for a brilliant recipe!

I made this bread last night, seasoning it with Everything seasoning and then put some cream cheese and lox on it. Delicious. Tonight I made it again, put some Greek seasoning in it to go with my Greek omelet. Had some time so I spread it on parchment and baked it in the oven.. It was wonderful with crispy edges and I think it would work as a pizza crust! First time used a whole egg. Tonight I whipped up an egg white. I didn't notice any eggy taste in either one.
Alison
Unbelievably good - this gives the whole ‘proper toastie’ experience in a lo carb way - honestly better than previous regular cheese toasties I have had 🙂 This not only tastes great but is total soul food and covers those times when you just don’t want another eggy or coconutty thing 🙂
We used an 8” by 8” pan and increased ingredients by 2.5 times and that made enough as a snack for 2 hungry adults. We made a second batch of that same size and that turned the snack into a satisfying lunch.
Terry
OH, MY! OH, MY! This is AMAZING! I didn't have a 5 x 5 pan so I went with a large mug and ended up with a round bread, kinda like an english muffin! I cut it in half, toasted it and buttered it and realized that I could easily make an egg, sausage and cheese muffin! It's SO yummy and super easy to make in the mug! Put everything in and stir it! Then I scramble the yolk add some veggies on the side and YUMMY!!! Thank you for this awesome recipe!

How long should I microwave this for as I only have a 700w microwave?
Katrin Nürnberger
My microwave operates at 900 Watts. So, your bread will take slightly longer. Try an additional 10 seconds.
Kathie La Rooij
This is my daily go to bread. I love it and it's so quick and easy.
Actually I love all Sugar free Londoner recipes!!

How can I make your keto bread if you don't have a microwave?
Katrin Nürnberger
I would bake it ay 180C / 350F for about 12-15 minutes, then check if it's done. But if you're turning on the oven anyway, why not make an entire loaf, such as this almond flour bread or my everyday low carb bread.
Kathie La Rooij
If you have an air fryer you can make it in that.
Katrin Nürnberger
Yes, that should work. I would set it on the same temperature as I cook in the oven - 180C or 350F. It will probably take around 10 minutes.
