For me, there aren’t many things better for lunch than a grilled cheese sandwich.  As a child, my grandma used to have a toasting machine, I would love to spend ages faffing making us both cheese toasties for lunch. 

As an adult, a grilled cheese sandwich was something that I had not had for years until I was at a Christmas market and they were selling these. 

Obviously, they were using bread and were not keto-friendly, however, it inspired me to create this keto toastie at home.

Can I Eat a Grilled Cheese Sandwich On Keto

Almond Flour

The most popular and keto flour used by those following a keto/low carb lifestyle by far is almond flour.  A 100g of almond flour contains 14g of fat 6g of protein and only 10g of carbs making it a good flour substitute for a keto lifestyle. 

Almond flour is made from finely ground almonds, with their skins removed. 

However, I have found that it can be quite expensive within supermarkets and it can be found cheaper online, especially when bought in bulk.

Psyllium Husk

Psyllium husk is an ingredient that regularly pops up in keto / low-carb recipes. It is nothing to be afraid of!

Psyllium is a form of fiber made from the husks of the Plantago ovata plant’s seeds; it is naturally high in fiber and low in carbs making it a great ingredient for us keto-ers!

As the almond flour is quite moist, the psyllium husk when toasted will bring a nice ‘crunch’ to your grilled cheese sandwich.

Filling Your Keto Grilled Cheese Sandwich

Cheese isn’t the only filling for these amazing sandwiches.  Use your imagination! 

Why not add some ham or even a bit of onion? 

That choice really is yours! 

I’ve put a few of my favorite combinations below;

Ham and Swiss cheese
Bacon and Brie
Pulled pork and smoked cheese
Cheddar, chili and chorizo
Shredded chicken avocado and cheddar

Check out this guide for how many carbs are in your favorite cheeses.

Making Your Grilled Cheese Sandwich

For me, I throw all of the ingredients in my Nutribullet and blend them together.  This ensures that the ingredients are fully combined and that there is plenty of air in the mixture. 

Getting plenty of air into the mixture ensures that the batter is light and fluffy which makes it rise in the microwave and gives it that lovely bread-like texture.  If you do not have a Nutribullet this can be done in any food processor or if necessary, with a hand whisk.  If are using a hand whisk ensure that the mixture is well-whisked sell lots of air bubbles can be seen.
