Are you making green bean casserole for Thanksgiving? Whatcha gonna do about those French fried onions that come in a can?
You know the ones I’m talking about, right? Rife with gluten and soy, made on the same equipment as products containing milk? And, well, they are in a can. I’ll give you that they are mighty tasty and delightfully crunchy atop a creamy casserole, but I also know they don’t work for many of us. I gotcha covered!
It doesn’t take much active time to whip up a batch of these at home. Perfect for those of us with some dietary restrictions. Or those of us that just like homemade ingredients. Or those of you who meant to buy them at the store and got home without them. You can make a batch at home in less time than it takes to drive to the store.
A few tidbits on making these: While not necessary, I do use a mandoline to slice my onion super thin. I have this one from OXO. I think it’s important when frying any food to keep an eye on the temperature of the oil. I use grapeseed oil and this thermometer for the best results.
French Fried Onions (gluten-free, dairy-free, soy-free)
Ingredients
- 1 Tablespoon apple cider vinegar
- 1 cup non-dairy milk (I use unsweetened almond or hemp milk)
- 1 yellow onion , thinly sliced
- 1 cup Johnna's Favorite Gluten-Free Flour Blend
- 1/2 teaspoon black pepper
- dash cayenne pepper
- grapeseed oil for frying
Instructions
-
In a liquid measuring cup, add 1 Tablespoon of apple cider vinegar. Top with non-dairy milk to the one cup mark. This will make one cup of a buttermilk substitute. Let sit for 10 minutes.
-
While milk is curdling, slice onion very thin with mandoline. ALWAYS use the handguard with a mandoline, protect your hands!
-
Place the thinly sliced onion in a baking dish. Top with buttermilk. Let sit for at least one hour on the counter. If you prefer, you can even let them sit in the buttermilk overnight in the refrigerator.
-
Mix flour, black pepper and cayenne together in a small dish.
-
Heat oil that is 2" to 3" deep to 350 degrees.
-
Remove a handful of the onions from the milk. Toss in the flour mixture. Carefully drop into the hot oil.
-
Fry for 1 to 2 minutes, until lightly browned. I give mine a quick stir about halfway through to keep them from clumping.
-
Remove from oil with slotted spoon and place on paper towel lined baking sheet.
-
If making ahead of time, store in an airtight container until used. I have stored these for up to 3 days before using.

My Thanksgiving plate is full, but I’m definitely making these for us after Thanksgiving! Longhorn Steakhouse restaurants call these onion petals, which is a perfect name I think. 😉
Thank you, Johnna!

I like the name “onion petals.” I agree, it’s perfect!

I just started Nutrisystem.. don’t like to many vegetables, but put the French onions on Sadat instead of croutons.. this recipe sounds great.. do you know how many calories for how many?
What kind of oil do you fry in.. olive.. coconut?
Thanks,
Teresa

Hi Teresa! I tend to fry in grapeseed oil. Olive oil has a low smoke point and isn’t a good choice for frying.
As for calories, I do not include calorie information for my recipes. You might try one of the many online calorie calculators so you can input your specific choices (oil, etc…)
Thanks for dropping by!
