Keto Onion Rings Ingredients

I use brown onions for this recipe. Brown onions are better suited to cooked recipes than white onions. I choose the largest onions I can find so that I get more onion rings out of each onion for this recipe. With the small centre pieces I reserve these for use in other recipes for later.

In tis particular keto onion recipe I have gone for a crumb coating rather than a batter. It gives you a perfect crispy onion ring, and it stays on the ring when cooking too.

As for the spices I use, you can of course exchange them for any of your favourites. I like the standard mix of onion and garlic powder, but I also add chilli powder and Aleppo pepper. Aleppo pepper isn’t a spice that is available in the supermarket locally but I get mine from The Essential Ingredient.
