Homemade French Fried Onions

Jump to Recipe 0 Comments

Victoria Pruett Author: Victoria Pruett   Updated: November 5, 2025

Crispy, crunchy, and delicious to pop in your mouth, these homemade French fried onions may not make it to the green bean casserole! Fry them in your choice of oil, and coat them with your favorite flour. We use einkorn flour and coconut oil, but you can customize them to your needs. Make them in advance and store them until you need them!

It’s no secret that I prefer to make our holiday meals completely from scratch! That means that even items we consider ingredients, such as marshmallows for sweet potato casserole or a can of jellied cranberry sauce, have to be made from scratch. I love the ability to control the ingredient quality of the food I serve to my family, and this is one more way I’m able to do that.

These homemade French fried onion toppers are something I would have historically grabbed to take home and make my green bean casserole “from scratch”! Now, even the toppers are truly homemade!

French Fried Onions

We love French fried onions around here. In fact, most of the time we eat an entire batch before we even make the green bean casserole! If your family is anything like mine, plan to make at least 2 batches of these in order to have enough to top your casserole!

Another great way to enjoy them is freeze-dried, as they will stay crisp forever that way!

But even if you don’t freeze-dry them, they can be made 2-3 days in advance and stored in a Ziploc bag at room temperature until you are ready to use them.

This recipe is very similar to my Southern fried okra recipe and is very easy to throw together!

a close up of how thin the onions should be sliced, about an 1/8th of an inch thick.

Step One:

Slice your onions AS THIN as you can. This really helps with the crunch.

Onions that are too thick will just turn into onion rings. Which, while delicious, are not French fried onions!

Keep onions cold or diffuse a citrus essential oil to help with the tears from cutting to many onions. Slice fast and take breaks, if needed.

two bowls, one with flour in it, and the other with the egg coated onion slices ready to dredge.

Step Two:

Beat eggs in a separate bowl and pour over sliced onions.

Massage onions gently to avoid breaking, until all onions are well coated.

Step Three:

Lift the onions out of the egg wash, leaving any extra egg in the bowl, and place the onions in a new bowl or baggie.

Cover in flour and toss (or shake, if you’re using a baggie) until onions are well coated.

NOTE: You can leave the onions in the egg bowl and just add the flour there. That’s what I do, but sometimes the eggs mix with the flour to create a softer coating after it’s fried. Give it a try if you want (like I said, it’s how I do it), but you might end up with more batter and less crunch than you want!

Step Four:

Fill a heavy-bottom pan to about 1-2 inches deep with frying oil of your choice, we use coconut oil. Heat oil to 350° over medium heat and start to fry onions in small batches.

When the fried onions are golden brown, remove from oil and place on a paper-towel-lined plate/tray to drain.

Repeat until all onions are fried. Salt to taste and mix the onions a bit once they are all fried!

Storing Homemade French Fried Onions

Once your fried onions are cooled, place them in a ziploc bag for 2-3 days at room temperature. You can also freeze them for up to 6 months.

My absolute favorite way to store our homemade fried onions is to freeze-dry them! They get SUPER crunchy and stay that way for years!

So, when I find onions on sale, I make a huge batch (like 25 pounds worth) and freeze-dry them for snacks throughout the year and for green bean casserole during the holidays!

NOTE: As with all my recipes, you can use einkorn flour or any wheat to create this delicious treat!
