Keto onion bread with butter & a lil chilli flakes

I’ll tell you right now, this amazing keto onion and cheese bread goes into the oven smelling delicious and comes out smelling even better – if that’s possible/ It is probably a new go-to when I want some toast in the morning or it would even be great used as a toastie of grilled cheese!
So before we begin with the recipe – a few notes. It’s important to try and chop up the onions, garlic and shallots as small as you can. It’s important because the larger they are, the more moisture will be released into the bread as they cook. If theres too much moisture, the inside may not fully cooked when you take it out.

Secondly, as per all of my other bread recipes, there is no substitute for the protein. You could try other proteins, such as egg or pea, but as of right now, I have yet to find a suitable alternative. 


Honestly, this keto onion bread is definitely one for the books! If you’ve tried it, I’d love to see your pics! Just send them to me on Instagram @hungryelephant

Could one use dehydrated onion flakes in place of the shallot to avoid a possible moisture problem?

Where is here? I’m in Ontario and I bought a box on Amazon for $20. it has about 10 cups worth in it, and it’s worth every penny!

I’m in Ireland at the moment but returning to Ontario in the new year so I’ll definitely be trying it when I get back. I think you can get it at Loblaws.. I swear I remember it being near the bread at No Frills!

I get it from The Low Carb Grocery web site. I live north of To. They also have 3 stores here. One in Markham, one in Newmarket and one in Vancouver. Delivery is relatively cheap, comes by mail. It used to by $7.00 flat rate for the total of the purchase. Not sure what it is now, has been a year or so since I have ordered from them. I have never seen it in the stores. Going to try this recipe, looks delish!
