🧾 Ingredients
- Tony Chachere's Seasoning is a spicy blend that I add to the flour -there's a link in the recipe or you might like to try my copycat Tony Chachere's seasoning.. You can substitute salt and pepper if you like.
- Peanut Oil is my favorite for frying as long as there are no allergies. It's got a high smoke point and fries clean and crispy. Other oils to use are: safflower, grape seed, or canola.

📞 The last word
A few years ago Thanksgiving came and I was madly throwing things together trying to get everything done. I realized at the very last minute that I did not have the crispy onions for the top of the green bean casserole.
Quelle horreur!
I did what any red-blooded American foodie would do... I had a meltdown.
Once that was out of the way I figured out how to make my own copycat French's onions. And I like them SO much better.
I will never go back to the store-bought French fried onions again. These are so good!
We love them on top of this crack chicken chili.

Do you think I could make a gluten free version of this french fried onions recipe? My daughter and I both have gluten allergies, and every Thanksgiving and Christmas I spend a million dollars on the store-bought gluten free version--let alone trying to even track it down! I wonder if it would be cheaper and tastier if I made it at home!
