Here’s What You Need
- 2 pounds cipollini onions (peeled and sectioned)
- 2 large eggs
- 1 cup buttermilk
- 2 cups all-purpose flour
- 1 tablespoon paprika
- 1 tablespoon kosher salt
- 1 tablespoon pepper
- 1 teaspoon garlic powder
- 1 teaspoon cayenne pepper
- Vegetable oil (for frying)
- ¼ cup mayo
- ¼ cup sour cream
- 1 tablespoon ketchup
- ½ teaspoon paprika
- A couple pinches of salt and pepper
Let’s Get Cooking!
1. Prep Time (10-15 minutes)
Start by preparing those adorable little cipollini onions. Slice off the root end carefully, remember, you want to keep the onion mostly intact, so just take off as little as possible. Peel those layers off gently, too. They can be a bit slippery, but I find that this helps keep everything neat. Next, grab a sharp knife and cut each onion into eighths vertically, again being cautious not to slice all the way through. You want those onion petals to stay together!
Once you’ve sliced all your onions, press them gently to separate the sections a bit. Toss these beauties into a bowl with the buttermilk and beaten eggs. Let them hang out and soak in all that goodness for about 5-10 minutes, but seriously, you could even do this step the night before and stick them in the fridge for a super easy weeknight meal!
2. Make the Flour Mixture
While the onions are soaking, whip out another bowl and combine 2 cups of all-purpose flour with 1 tablespoon paprika, 1 tablespoon kosher salt, 1 tablespoon pepper, 1 teaspoon garlic powder, and 1 teaspoon cayenne pepper. Mix it together until everything is well-blended. This mixture is going to create those perfect, crispy layers on your onions!
3. Coat the Onions (5 minutes)
Once the onions have marinated, it’s time to dust them up! Remove them from the buttermilk (a little splash isn’t a problem) and toss them in the flour mixture. Be sure to get that flour into all the cracks and crevices, this is what makes them “bloom” beautifully when they fry. Move those coated onions to a clean plate, don’t crowd them; just let them chill there for a moment.
4. Frying Time (4-5 minutes)
Grab a pot or a deep pan and heat up some vegetable oil to about 350 degrees F. You want enough oil to submerge the onions but not so much that you’re using it like water! Once it’s hot, drop in those bite-sized onions carefully (maybe a few at a time). Fry them for about 4 minutes or until they’re golden brown and crispy. Ah, it’s so satisfying to watch them puff up! When they’re done, remove them from the oil and let them drain on a paper towel for just a minute. Serve ‘em hot, fresh from the fryer!
Dipping Sauce Preparation (5 minutes)
While your onions are frying, you can whip up the dipping sauce! Just mix together ¼ cup mayo, ¼ cup sour cream, 1 tablespoon ketchup, ½ teaspoon paprika, and a couple pinches of salt and pepper. It’s creamy, tangy, and the perfect complement to those crispy onions!
