Down here in the South, onion rings aren’t just a snack—they’re a way of life. Using Vidalia onions, with their sweet, mild flavor, we give ‘em a dip in buttermilk, coat them in a crispy, golden batter, and deep-fry them to crispy perfection. It’s like a tobacco onions method, but with way less work and a lot more crunch. We’re talking about a dish that takes a centuries-old southern classic and gives it a crispy fried makeover.

The spice blend? Oh, it’s got paprika, garlic powder, and just a hint of cayenne pepper—enough to remind you of those smoky tobacco onions, but with a little extra kick. These crispy little guys didn’t just appear out of thin air; they’re the evolution of a southern experiment that’s now a full-on food obsession. So, grab your favorite dipping sauce and dig in—these Southern Buttermilk Onion Rings are about to become your new burger and steak BFFs.

A Buying Guide for Onions

When embarking on this recipe, choose medium sized Vidalia onions (or other sweet white onions) that are firm with smooth skin and no blemishes. They should feel heavy for their size, which indicates freshness. For the best crispy onion rings, make sure to slice the onions into 1/2-inch-thick rings—thin slices can fall apart while frying.

Recipe Shortcuts

  • Make-Ahead – Coat your onions ahead of time and store them in the fridge. Then, simply fry when you’re ready.

Beer, Wine and Cocktail Pairings 

Pairing your crispy southern buttermilk onion rings with the perfect beverage can elevate your dining experience. For beer enthusiasts, a light lager or pale ale complements the savory crunch and subtle heat of the onion rings. The slight bitterness of these beers balances the richness of the fried batter, while their refreshing qualities keep your palate clean between bites. If you’re after something with a little more punch, a hoppy IPA can add a bold contrast to the sweet Vidalia onions.

If wine is more your speed, go for a chilled Sauvignon Blanc or Pinot Grigio. Their acidity cuts through the richness of the onion rings, while the citrus notes enhance the slight sweetness of the onions. For cocktail lovers, a spicy margarita or whiskey sour brings the perfect amount of heat and depth to balance out the crispy goodness. Whether you’re sipping or munching, these pairings will take your onion ring game to a whole new level.

How to Serve

Keep it easy and whip up a killer dipping sauce like my Pub Sauce or Five Ingredient Honey Mustamaise—both are a breeze and pack a punch. If you’re feeling a little Cajun flair, Remoulade is your friend. But let’s be real—these bad boys are KILLER on top of a burger or, my personal fave, perched atop a juicy grilled steak. Trust me, it’s the kind of upgrade your meal’s been begging for.

Make-Ahead and Storage Instructions

To make your onion rings ahead of time, coat the slices as directed in your recipe and lay them in a single layer on a parchment-lined baking sheet. Chill them in the fridge for at least 30 minutes—this helps the coating adhere and ensures a crispy finish. When you’re ready to serve, fry the chilled rings in hot oil until golden and crunchy. For best results, avoid freezing the uncooked, coated rings as it can lead to sogginess, and reheat any leftovers in an oven or air fryer to revive their crispiness.

Ingredients 

  • 3 medium sweet onions such as Vidalia, you can also use red onions
  • 1 cup all-purpose flour, substitute gluten-free flour for a gluten-free version
  • 1/2 teaspoon sweet paprika
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon ground cumin
  • 1/4 teaspoon cayenne pepper
  • pinch sea salt, more to taste
  • 1 cup buttermilk
  • peanut oil, may also use vegetable oil

Instructions 

  • Peel and slice 3 medium sweet onions into 1/4-inch thick rings. Separate each slice into individual rings to ensure even cooking.
    3 medium sweet onions such as Vidalia
  • In a large bowl, combine 1 cup of all-purpose flour (or gluten-free flour for a gluten-free version), 1/2 teaspoon sweet paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon ground cumin, 1/4 teaspoon cayenne pepper, and salt to taste.

    1 cup all-purpose flour, 1/2 teaspoon sweet paprika, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon ground cumin, 1/4 teaspoon cayenne pepper, pinch sea salt
  • Pour 1 cup of buttermilk into a separate bowl. This will serve as the wet coating to help the flour mixture adhere to the onions. Dip each onion ring into the buttermilk, allowing any excess to drip off, then dredge it in the flour mixture, ensuring all sides are well-coated. For an extra crispy texture, repeat the dipping and dredging process to create a double coating.
    1 cup buttermilk
  • Place the coated onion rings on a plate. Let them rest for about 10 minutes to help the coating adhere better.
  • In a deep, heavy-bottomed saucepan or deep fryer, pour enough peanut (or vegetable) oil to reach a depth of at least 2 inches. Using a deep-fry thermometer, heat the oil to 365°F (185°C). Maintaining this temperature is crucial for achieving a crispy exterior without overcooking the onions.

  • Carefully lower a few onion rings into the hot oil, being mindful not to overcrowd the pan, as this can lower the oil temperature and result in greasy rings. Two large onions take me 4 to 5 batches. Fry for 2-3 minutes, turning occasionally, until they are golden brown and crisp. Use a slotted spoon or spider strainer to remove the rings, allowing excess oil to drain back into the pan. Transfer the fried onion rings to a baking sheet lined with paper towels to absorb any remaining oil. While they are still hot, season lightly with additional salt if desired.
  • For the best texture and flavor, serve the onion rings hot alongside your favorite dipping sauces.

Notes

Make Ahead – coat the slices as instructed and place in a single layer on a parchment-lined baking sheet. Refrigerate. When ready to serve, fry the chilled rings in hot oil until golden and crunchy. Avoid Freezing.
Storing Leftovers – place in airtight container fitted with a lid. Refrigerate up to 3 days before reheating.
Reheat Leftovers – place in an oven or air fryer to re-crisp.
