Homemade Onion Straws

For the longest time, I viewed onion rings as nothing more than a vehicle for whatever sauce they were served with. More often than not, I’d tear them in half, carefully pull the onion out and toss it aside, and then proceed to dip the remaining breading in the sauce. Onion rings, sans onion.

But then I was introduced to onion straws and I’ve never looked back. The onion is thin enough that I don’t have an issue with the texture, and it adds the perfect amount of flavor to the otherwise perfect breading.


Eric and the kids all love these Homemade Onion Straws just as much I do. Eric is probably the only true fan of onions in our family, but when these are on the menu, we all happily over-indulge. They are great on their own as an appetizer, or as a topping for many things, included sandwiches, soups, and casseroles. I’ve successfully duplicated this recipe with a gluten-free all-purpose flour and had equally outstanding results as when using non-GF flour.
