What’s 90-second keto bread?

A Microwave keto bread is a low-carb bread recipe cooked in the microwave bread for only 90 seconds to quickly fix your bread craving. It’s the perfect low-carb keto bread recipe to make a quick breakfast sandwich or toast.

How to make keto 90-second bread?

It’s very simple to make a keto microwave bread.


All you need to make yours are 6 simple ingredients:

  • Almond flour or almond meal – both options work very well. However, almond meals make the bread darker in color and a bit gritty in texture. If you are a keto beginner, I highly recommend ultra-fine almond flour to enjoy this keto bread 90-second recipe. Read how to choose your keto flours to become an expert!
  • Coconut flour – the combination of both flours creates the best bread texture, similar to wheat-based bread, without the carbs. If you don’t have coconut flour, you can replace it with more almond flour, but the bread crumb will have a softer, more cake-like texture.
  • Egg – this recipe needs an egg. It won’t work with egg replacers like flax egg or chia eggs. Try my egg-free 90-second keto bread recipe if you are after an egg-free keto bread recipe or on a vegan keto diet.
  • Baking powder to give your bread a little rise.
  • Olive oil or melted butter.
  • Water

Combine the dry and wet ingredients

Now, in a small bowl, combine the dry ingredients. Then, add the beaten egg, water, and olive oil and whisk until a smooth batter forms.

Spread the batter in a microwave-safe bowl.

There is few different mugs or container you can use to bake your 90-second bread recipe.

  1. A regular 12 oz coffee mug – this is the best way to make a small individual bread loaf with a cylinder shape. Then, slice the bread cylinder into 4 thin slices.
  2. A microwave-safe square pan – to make triangle sandwiches as seen in my pictures. Cut the square in half to make triangles.

Check your microwave power settings

Most microwave runs at 900W, but some also run at higher power up to 1200W or lower intensity of 600W. Depending on the watts of the microwave, the regular 90 seconds of baking time won’t deliver the same bread texture.

In fact, when we call this recipe a 90-second microwavable low-carb keto bread recipe, it’s for a standard microwave setting of 900W!

Adjusting the baking time to the power of your microwave

If your microwave runs at:

  • 900W – microwave the bread for 90 seconds.
  • 600W – microwave the bread for 90 seconds, then add 10 extra seconds if the bread is still moist or wet in the center.
  • 1200W – microwave the bread for 60 seconds, then check the consistency and add an extra 10 seconds if it is still moist or wet in the center.
  • Don’t know what the power of your microwave is? Play it safe and microwave the bread at the minimum baking time of 60 seconds. Then, check the texture and return to the microwave by 10-second bursts until the center is set, not wet or liquid.

Remember that it’s always better to underbake microwave bread. In fact, you can always bring it back to the microwave in small 10-seconds bursts. But if you overcook it, it will be very dry and not pleasant to eat.

Toast the bread

Now that the bread is cooked, it’s very soft. So you have two options to give some texture to the bread.

  1. Toast in a bread toaster until crispy.
  2. Create a sandwich and toast in a sandwich press, spreading butter generously on the outside bread slices.
  3. Pan fry it in butter.
  4. Make keto French toast sticks.

The best toppings for this 90-second bread recipe are:

  • Peanut butter and keto chia seed jam.
  • Ham, cheese, and spinach.
  • Bacon and fried eggs to make a keto breakfast sandwich.
  • Cream cheese and bagel seasonings.

Tips to flavor your bread

Obviously, this microwave bread recipe intends to be neutral in flavor to be used in any way you like: sweet or savory.

Like any regular soft bread from the store, it’s a soft, airy bread with many possibilities!

Some of my tips to boost your bread with flavor are the addition of dry spices, cheese, or sweeteners.

Let’s see below some of the great flavors you can create with this simple recipe.

  • Keto cinnamon toast – add 1/2 teaspoon of cinnamon, pumpkin spices along with 1 tablespoon of sugar-free crystal. Melt 1 tablespoon of butter or coconut oil in a pan and fry the bread on both sides. Serve with sugar-free maple syrup.
  • Italian bread. Give your 90-second keto bread some Italian flavor, add 1 teaspoon of dried oregano, 1/4 teaspoon of salt, 1/4 teaspoon of ground paprika, and 1 tablespoon of grated Parmesan.
  • Garlic bread. Missing garlic bread? Try to add 1/4 teaspoon of salt, 1/2 teaspoon of garlic powder, and fry the bread in 1 tablespoon of melted butter.

A keto sandwich bread

While this is one of the best keto recipes for breakfast, it’s also an amazing keto sandwich bread.

Who doesn’t love a club sandwich? I am sure you do too! Not sure how to make a keto sandwich using this microwave bread recipe? Here are some great keto sandwich ideas for any time of the day.

90 second keto mug bread

  • Breakfast sandwich – bacon, scrambled eggs with cheese, and scallion.
  • Keto lunch sandwich – ham & cheese and spinach. Play with the cheese flavor, mix parmesan, Edam cheese, cheddar, or any cheese! Add some mayonnaise and pickles if you like!
  • Keto vegetarian – mayonnaise, avocado, thin cucumber slices, and baby spinach.

Finally, if you are not fond of eggs in your keto bread recipe but still want quick bread, try my egg-free keto bread in the microwave. As a result, the texture will be dryer, dense, and closer to artisan bread.

How to store keto microwave bread?

I hear you, you are busy, and you want to make ahead some quick, tasty keto bread. Contrary to oven baking, microwaving cooks your food so fast that the texture dries out very quickly if stored for too long.

Clearly, it won’t taste as good the next day, but it’s still possible to make it ahead 24 hours before. These are my recommendation.

  1. First, cook the bread in the microwave and cool down on a rack until it reaches room temperature.
  2. Next, wrap your keto bread in plastic film to keep it moist and place it in the fridge.
  3. Finally, the next day, toast your bread in the toaster or pan fry in butter.

  • In a small mixing bowl, stir almond flour, coconut flour, and baking powder. Set aside.
  • In another bowl, beat the egg with olive oil and water.
  • Whisk the liquid ingredients into the dry ingredients until a smooth runny batter forms.
  • Spray oil on a tall 12 oz coffee mug or a microwave-safe pan. I used a square 6-inch x 6-inch ceramic pan.
  • Pour the batter into the coffee mug or spread evenly into the pan.
  • Microwave on high (900W) for 90 seconds until the bread is cooked through. If your microwave has a lower or higher power setting, read my post above for baking time recommendation.
  • Remove from the microwave carefully as it's hot. Then, use a sharp knife to loosen the sides of the bread and flip over a plate or chopping board.
  • If baked in a coffee mug, you end up with a cylinder shape, slice in 2 thick slices, or if made in a square pan, slice in half to make 2 triangles.
  • Bring each bread slice into a bread toaster and toast until crispy or make a sandwich, spread butter on the outside of the bread slices, and toast in a sandwich press or frying pan until crispy.
No microwave? You can bake the bread for 8-15 minutes in a ceramic oven-proof baking pan at 350F/180C. Stop baking when a toothpick inserted in the middle of the bread come out clean.
Storage: if you are using the microwave method, store for a maximum of 24 hours, in the fridge, wrapped in plastic wrap to keep the bread soft and moist. It is recommended to make this bread just before eating to enjoy all it is flavor and texture. 
This recipe serves 2 slices of bread. The nutrition panel is for one slice.

    Hi Carine

    Loving your recipes! Thank you!

    I have devised a similar bread recipe with 1 Tbsp (20ml) coconut flour & 3 Tbsp (60ml) almond flour, 1 tsp (5ml) baking powder, 2 eggs, 1 Tbsp (20ml) MCT oil.It makes 4-5 slices depending on how thin I cut it.

    If I was to double the size of your recipe, could I get away with one egg and 1/2 Tbsp Oil?

    • I live in New Zealand and I found this in my local supermarket. Otherwise you an bake this recipe in mug or ramekin and slice. It will make round slices perfect for a sandwich too. Enjoy the recipe, XOXO Carine

  2. Hi, I gave this a try – tastes great by the way. The only thing is when I entered the recipe into My Fitness pal (scanned the ingredients I used) the nutritional information differs hugely from yours, specifically the calories which for mine is 356 calories per slice. I realise different brands vary, but surely the caloric results shouldn’t double. Does this make sense to you?

    • My recipe serve 2 maybe you enter the whole recipe as 1 serving which explain why the calories on my fitness pal are two times mine. Enjoy the recipes on the blog, XOXO Carine

    • I can find coconut flour in my regular supermarket here in New Zealand. It is sold next to regular wheat flour. In Europe I know you buy it from health food store or organic store. Enjoy the recipe, XOXO Carine

    • Thanks for trying my recipes ! I am French so English is my third language and always a big challenge to write in English. I will try to correct as much as I can. Thank you, XOXO Carine.

    Two thumbs up. Enjoyed EVERY bite. Have been looking forward to a sandwich, ticked all the boxes for us. I had a leftover roast meat , lettuce, tomato, cucumber and mayo. My partner cut his toast into bite sized portions, and had smoked salmon etc, and absolutely devoured his. Will be a repeat recipe in our book.

    Just made this today and WOW! I cannot have almonds, so the one substitution I made was using sunflower seed meal instead of almond flour and let me just say it still turned out beautifully! My husband was quite skeptical when hearing I was making bread in the microwave, but when he tried it he loved it…even more than standard rye bread. I’ve made several Keto mug bread recipes and truly love this one. Thank you so much for sharing.

    • I am so happy to read your comment and if it passed the hubby test it means a lot right ? 🙂 I didn’t try the recipe with sunflower seed flour so I am glad to hear it work. A great nut free keto bread options 🙂 Thanks again for trying my recipes, XOXO Carine.

    Tonight was my 4th time to make this. First time I made for my husband. I’m diabetic so I have to eat low carb, the husband isn’t. I decided to have egg frittata and ham for dinner and thought why not? Let’s have the keto bread. He LOVED it. Said it reminds him of crumpets1 Thanks you again for another great keto recipe.

    • I love when hubby gets on board especially if he doesn’t have to eat low carb! That is wonderful that you both can share the same food. Thanks for the lovely feeback. Enjoy the low carb recipes on the blog, XOXO Carine.

        Hi! I am writing from Italy and I love your recepies, about this one though I am a bit confused. If I read the ingredients above you write baking powder but from the comments below it seems like you use baking soda (which I prefer because I am intolerant to baking powder) so, what’s the right measure for baking soda? Thank you so much

  6. Hi! I tried the recipe yesterday but it crumbled a bit when I made a sandwitch. What could have gone wrong? I used a little more water in the recipe because it wasn’t as liquid as yours, and I baked it in a plastic container for 30 more seconds in the microwave. Oh, and I used baking powder.
    I also wanted to ask if I could use two egg whites instead of a whole egg, because I don’t like the eggy flavor so much. Actually, I am going to try it today and let you know the results, but if you have already tried it, I’d like to know how it came out. Thank you!

    • Sure 2 egg white should work but you shouldn’t bake more than 90 seconds and don’t add any extra liquid. It probably crumble because it was too dry as you cook your bread longer. Microwave dry out food very quickly, and an extra 30 seconds burst is actually a lot. Thanks for trying my recipes, XOXO Carine.

  7. In the nutritional facts it states 2 slices – 161 calories is that for 1slice or 2 slices
    (This recipe serve 2 slices of bread. Nutrition panel is for one slice. One slice contains 3.2 g net carbs.

    • Yes this recipe makes 2 slices and I provide the panel for only 1 slice simply because we all have different macro target. People on keto may want to enjoy only one slice while others on low carb may go for the whole recipe, 2 slices. Simply serve as much that you can fit in your macro and daily meal plan. Enjoy, XOXO Carine.

    Just made the 90 second bread! Love, love, love it! Looking forward to using more of your recipes. Just signed up.

    Well, this time I tried the recipe again using baking powder instead of baking soda. What a difference! It tastes like a coconutty nutty healthy yummy bread. The recipe that had baking soda only tasted like baking soda. It literally tasted like eating straight baking soda but in bread form. My suggestion to those who have not tried this recipe yet is to make it with the baking powder. You will be glad that you did! On a scale of 1 to 10 it went from a minus 5 (baking soda recipe) to a plus 8 (baking powder recipe) I love it now, and I love that I can make it so fast and so easy when there is not a lot of time to cook.

    • Thank you so much for taking the time to retest the recipe with baking powder ! I am so happy that you now enjoy this simple bread recipe because it is such a life saver when you crave bread! Enjoy the recipes on the blog and thanks for this amazing comment that will help many others. XOXO Carine.

    Hi Carine
    I just madethis 90 seconds bread. I roasted It in the pan and topped with ham and cheese. It would be délicious but for one thing : I didn’t like the taste of baking soda( 1/2 teaspoon). Is It nécessary in the list of ingrédients and could I replace It by baking powder or xantham gum?
    Always a pleasure to taste your succulent recipes.

    • Hi ! I am glad you enjoy the recipe. As I replied to many you can always swap baking soda for baking powder if you don’t appreciate the flavor of it. Use 1/2 teaspoon of baking powder instead of the baking soda and it will be perfect. Enjoy the recipe on the blog and thank YOU so much for your lovely comment. XOXO Carine.

  12. I followed this recipe to the T. It came out wet, not dry, and took longer than the 150 seconds instead of 90 to cook (twice I did it for 30 seconds more) But worse than all of that, it tasted like baking soda! I am not a perfectionist in taste, but it tasted completely like baking soda so much that it felt like I was eating soap and even got worried that something else had gotten in there. It took over an hour, lots of water drinking and eating real bread to get the taste out of my mouth. This recipe looks so good on your blog so I was very disappointed. I went over the recipe 3 more times to see what I could have done wrong but it was all the same measurements. Are you sure there is no typo in this recipe? Are you sure it should be that much baking soda, or maybe there should be more flour? I had to throw the rest away because I could not offer it to my husband after what happened to me. There must be some mistake here.

    • The recipe is absolutely fine, I made this many times. Baking soda is not to the taste of everyone and you can always substitute for baking powder in a recipe. Make sure you are using 2 times more baking powder. So if the recipe calls for 1/4 teaspoon baking soda replace by 1/2 baking powder. If your batter is too wet it might be because your coconut flour is not fresh and it has lost its absorbent properties or your egg is very big. I recommend you add the water 1 tablespoon at a time and stop when it has a cake batter texture. The texture must be thick but liquid and wet. I hope you had better results next time. XOXO Carine.

    • Baking powder is basically made of 50% baking soda and additives that could includes starch. So if you want to aoid additives you use baking soda and use half the amount of baking powder. Not everyone enjoy the flavor of baking soda so it is up to you to use it or use double amount of baking powder instead. Enjoy the bread! XOXO Carine.

  13. My batter is coming out too dry. Any suggestions for what I can do. I used your exact measurements.

    • I might be that your egg is small and you are mixing liquid. Did you follow the recipe in grams for precision. Otherwise add a 1 tbsp of water or milk and it will come out great. XOXO Carine.
