Ingredients
2.5 cups buttermilk 4 cups thinly sliced onions, halves and rings of small onions 3 cups All-purpose flour 1 tsp kosher salt 1/4 tsp ground pepper 4 cups vegetable oil
Method
- 1. Soak the sliced onions in buttermilk for at least 10 minutes. This will add flavor and soften the onions slightly.
- 2. In a shallow dish, combine the flour, kosher salt, and fresh ground pepper. Mix until the coating is evenly seasoned.
- 3. Heat the vegetable oil in a large pan to 375°F (190°C). Test the temperature with the handle of a wooden spoon—bubbles should form around it when the oil is ready.
- 4. Dredge the buttermilk-soaked onions in the flour mixture until fully coated. Fry the coated onions in small batches until golden brown.
- 5. Remove the onion rings with a slotted spoon and place them on a paper towel-lined plate to drain excess oil. Serve hot for the crispiest texture.
- 6. If storing, transfer cooled onion rings to an airtight container. They can be kept in a cool, dry place for up to a few days.

Regional Variations
These onion rings aren’t just a relic of the past—they continue to evolve. Many regions and cultures have put their own spin on the dish. In the southern United States, the addition of buttermilk to the batter became a hallmark, lending a tangy richness to the coating. Variations have emerged worldwide, with panko breadcrumbs, tempura batter, or even beer batter offering new textures and flavors. Despite these adaptations, the essence of onion rings remains universal: a simple yet indulgent snack that brings people together.
Today, onion rings are a favorite for game days, family gatherings, or as an indulgent treat. Their versatility makes them perfect for customization.

For a healthier twist, they can even be baked or air-fried to retain their signature crunch without the oil.
