❤️ Why you'll love this recipe

  • better than the original crispy fried onions
  • perfect to top casseroles and for salad toppings
  • don't do Thanksgiving or Christmas dinner without them!

Quick, easy, and money saving!

These are so delicious with that crunch texture we all love - and no worries about the store being sold out during the holidays.

After all, what's green bean casserole without those crispy fried onions on top?

🧾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.

💭 Tips

Expert Tip: The trick for copycat French's fried onions is to slice the onions super thin and fry them until they are crispy but not burnt.

  • Deep frying in oil is the best way to make fried onions. Air fryer and oven methods are ok but not as good as frying.
  • Use a large mild onion like a 1015 onion.
  • Let them soak in the buttermilk longer if the onions are very strong.
  • Drain as much buttermilk as possible off the onions before dredging in the flour.
  • If you don't have buttermilk you can use regular milk.
  • Use these crispy fried onion strings on top of any casserole the way you would with Durkee or French's.
  • Grind them into crumbs and use them to coat the chicken.
  • Homemade French fried onions are fabulous on burgers and hot dogs!
  • Eat for a snack.

👩‍🍳 FAQs

📞 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.

Notes

Tips

  • If you don't have buttermilk you can use regular milk.
  • Use these on top of any casserole the way you would with Durkee or French's.

  • Fabulous on burgers and hot dogs!

Can these French fried onions be made gluten-free?

They can! Just substitute gluten-free flour for the flour in the recipe. It couldn't be easier! Be sure to double-check any seasonings you add for gluten.

Storage:

Store French-fried onions in an airtight container in a cool pantry for a day or two. Make sure you've cooked them thoroughly. You may need to crisp them back up for a few minutes in an air fryer or oven.

For safety's sake, it's probably better to put them in the fridge if you are going to keep them longer and crisp them up when ready to use again.

    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!
