There is nothing quite so satisfying as picking up a big, melty slice of grilled cheese sandwich and biting into that melty goodness. Especially when it's low-carb!

I thought these days were behind me, until I discovered 90 second bread. Now, I just want to make up for lost time by eating a different grilled cheese sandwich every day. I have included some of my favourite variations below. Enjoy!

Extra tip from a reader: substitute part of the almond flour with flax meal for a better flavour and no eggy taste.

If you have time to make a whole loaf of low-carb bread, apart from our 90-second bread you can use our Ultimate Keto Bread, Soul Bread or Fluffy Grain-Free Sunflower Bread.

“bake 350 °F for 12-15 minutes” for what dimension of the container?


About the same as the bread container, just ovenproof. It should be about the size of a regular slice of bread. A ramekin (1 to 1.5 cups)  is another option - to create a "mug muffin".


This was a great alternative to other keto bread recipes I've found, which were reminiscent of sawdust but without the flavor. This was a little too dry though, how can I give it more moisture and stay keto?


Thank you Amy! You could add moisture by adding one more tablespoon of olive oil or melted butter/ghee. Or you could add a tablespoon of cream cheese (if you can do dairy).


90 second bread has become my fav! I make it in the oven and add faux apple pie filling on top to get a  apple fritter/breakfast  treat.  I tried using protein powder instead of almond, doesn't work....stick to the recipe. I have sprinkled with almonds instead of faux apple pie but I like the apple pie.


Thank you for sharing this Sher! I wonder about the faux apple pie topping, did you use zucchini? 😊


What size of ramekin?


These are made in shallow sandwich containers, about the size of a loaf but you could use a large ramekin too, I think that 1-cup ramekin will work just fine.


Where did you find the square bread storage container?  What is it made of?


Hi Sharon, something like this will work: Amazon link
Or you can even use a square glass container like this one: Amazon link


Made it. Quick and easy.  I made it in the oven just because I wanted that browning effect. Next time I will try microwave. I really crave that yeasty flavor. Do you know of anything that could be added to get that flavor?  


Hi Sher, I am actually working on a keto yeast bread recipe so you should see it on the blog in the next few weeks 😊
