How to Make Onion Strings

Making these delectable Onion Strings is a straightforward process, I promise! It begins with thinly slicing your yellow onions and giving them a good soak in buttermilk to tenderize them and help the coating adhere. Next, you’ll whip up a flavorful dry coating and toss your onions until they’re perfectly covered. Finally, they take a quick dip in hot oil until they are golden brown and wonderfully crispy. It’s a method I’ve perfected over the years, ensuring every single strand is a crunchy delight. For another amazing onion-infused dish, I highly recommend checking out this caramelized onion hummus.

Pro Tips for Making This Onion Strings

Achieving the perfect batch of Onion Strings is truly an art, but one that’s easily mastered with a few of my favorite kitchen secrets.

Prepping Your Onions Just Right

The thickness of your onion slices truly matters here. I always aim for about 1/8-inch thickness – thin enough to get crispy quickly but still substantial enough to offer that sweet onion flavor. A mandoline slicer is a game-changer for consistency, but a sharp knife and a steady hand work beautifully too. Remember, even slices ensure even cooking!

The Buttermilk Soak Advantage

Don’t skip the buttermilk soak! This step isn’t just for flavor; it tenderizes the onions and creates the perfect surface for our dry coating to cling to. I find that a good 30-minute soak yields the best results, ensuring a really well-coated and flavorful batch.

My Secret Trick: When coating the onions, I always work in small batches. Overcrowding the bowl means some onions won’t get adequately coated, leading to uneven crispiness. A little patience here goes a long way to ensure every single strand is perfectly battered and ready for frying.

Frying for Golden Perfection

Temperature control is crucial when frying. I use a thermometer to maintain the oil at a consistent 350-360°F (175-180°C). Too low, and your Onion Strings will be greasy; too high, and they’ll burn before they crisp. Fry them in small batches too, to avoid dropping the oil temperature too much and ensure they get that beautiful golden-brown color and irresistible crunch.

How to Store Onion Strings

If, by some miracle, you have any leftover Onion Strings – which rarely happens in my house! – proper storage is key to preserving their deliciousness. I always recommend letting them cool completely before transferring them to an airtight container. They’ll keep well in the refrigerator for up to 2-3 days. To reheat, I simply pop them in a preheated oven or air fryer at around 350°F (175°C) for a few minutes until they’re hot and crispy again. Reheating them slowly in the oven truly brings back their incredible texture, almost as good as fresh!

Nutritional Benefits

While often enjoyed as a delightful treat, these Onion Strings do offer some surprising benefits. Onions themselves are packed with antioxidants and beneficial compounds. When I incorporate them into family meals, I always feel good knowing we’re enjoying something both delicious and naturally flavorful, making this appetizer a lovely addition to our rotation.

FAQs

Can I make Onion Strings ahead of time?

While Onion Strings are best enjoyed fresh for maximum crispiness, you can prepare the sliced and coated onions a few hours in advance. Store them in the refrigerator on a wire rack over a baking sheet to prevent them from getting soggy, then fry just before serving.

What kind of oil is best for frying Onion Strings?

I always use vegetable oil or canola oil for frying Onion Strings. These oils have a high smoke point, which is essential for achieving that beautiful golden color and ensuring they cook through without burning. Always use fresh oil for the best flavor!

Can I bake or air fry these Onion Strings instead of deep frying?

While deep frying yields the crispiest results, you can certainly try baking or air frying for a lighter option. For baking, arrange coated Onion Strings in a single layer on a greased baking sheet and bake at 400°F (200°C) until golden. For air frying, work in batches at 375°F (190°C).

What are some good dipping sauces for Onion Strings?

The beauty of Onion Strings is their versatility! My family loves them with a classic spicy ranch, a tangy barbecue sauce, or even a simple garlic aioli. Don’t be afraid to experiment with your favorite creamy dips to find the perfect pairing for these crunchy delights.

Ingredients Equipment Method Notes

Ingredients

  

For the Onions

• 2 large Yellow onions thinly sliced (about 1/8-inch thick), separated into rings
• 2 cups Buttermilk

For the Dry Coating

• 2 cups All-purpose flour
• 1/2 cup Cornstarch
• 1 tbsp Salt plus more for seasoning after frying
• 1 tsp Black pepper freshly ground
• 1 tsp Paprika
• 1 tsp Garlic powder
• 1 tsp Onion powder
• 1/2 tsp Cayenne pepper (optional, for a kick)

For Frying

• 4-6 cups Vegetable oil or other high smoke point oil, for deep frying

Equipment

• Large mixing bowls (2)
• Whisk
• Deep pot or Dutch oven (3-4 quart)
• Slotted spoon or spider
• Paper towels
• Wire rack
• Sheet Pan
• Mandoline Slicer (optional)
• Deep-Fry Thermometer

Method

 

Prepare the Onions

• Carefully slice the peeled onions into very thin rings, about 1/8-inch thick. A mandoline slicer works best for uniform thickness. Separate the rings and place them into a large bowl.
• Pour the buttermilk over the onion rings, ensuring all onions are submerged. Let them soak for at least 15-20 minutes at room temperature, or up to 30 minutes in the refrigerator. This helps tenderize the onions and gives the coating something to adhere to.

Prepare the Dry Coating

• While the onions are soaking, prepare the dry coating. In a second large bowl, whisk together the all-purpose flour, cornstarch, 1 tbsp salt, black pepper, paprika, garlic powder, onion powder, and cayenne pepper (if using) until well combined.

Coat the Onions

• Lift a handful of onion rings from the buttermilk, allowing excess liquid to drip off. Transfer them to the bowl with the dry coating. Toss gently to ensure each onion string is thoroughly coated. Repeat with remaining onions in batches, ensuring not to overcrowd the bowl, and set aside on a separate sheet pan.

Fry the Onion Strings

• In a deep pot or Dutch oven, pour enough vegetable oil to reach a depth of about 3 inches. Heat the oil over medium-high heat until it reaches 350-375°F (175-190°C) on a deep-fry thermometer.
• Working in small batches, carefully add a handful of coated onion strings to the hot oil. Do not overcrowd the pot, as this will lower the oil temperature and result in soggy onion strings. Fry for 2-4 minutes, or until golden brown and crispy, turning occasionally with a slotted spoon.
• Using a slotted spoon or spider, remove the cooked onion strings from the oil and transfer them to a plate lined with paper towels to drain excess oil. Immediately sprinkle lightly with additional salt to taste.
• Transfer the drained and seasoned onion strings to a wire rack set over a sheet pan to keep them crispy while you fry the remaining batches. Repeat the frying process until all onions are cooked.
• Serve hot and enjoy!

Notes

For extra crispy onion strings, ensure your oil temperature stays consistent. If you don't have buttermilk, you can make a substitute by adding 1 tablespoon of white vinegar or lemon juice to a measuring cup, then filling it with regular milk to the 1-cup line. Let it sit for 5-10 minutes until it slightly curdles. These are best served immediately. If you have leftovers, they can be reheated in a single layer in an oven or air fryer at 350°F (175°C) until crisp again.
