Brown-Butter–Fried Onion Rings

This sophisticated take on a classic vegetarian snack elevates the humble onion ring into something truly special. By using a double-coating method with buttermilk and seasoned flour, each ring achieves a superior crunch that stands up perfectly to the frying process. The red onion provides a mild, sweet base that contrasts beautifully with the salty, crisp exterior, making these an irresistible accompaniment to burgers or a standout party nibble.

The real secret to this recipe lies in the use of nut-brown butter, which adds a deep, savoury complexity that standard oils simply cannot match. Frying in small batches ensures the butter stays at the correct temperature and the coating remains light and brittle rather than greasy. Serve these golden rings immediately while hot, perhaps with a cooling soured cream dip or a sharp pickle to balance the richness.

Ingredients for Brown-Butter–Fried Onion Rings

  • 240ml buttermilk

  • 240ml plain flour

  • Kosher salt, freshly ground pepper

  • 1 large red onion, sliced into 1/4-inch-thick rings

  • 8 tablespoons (1 stick) unsalted butter

Place buttermilk in a medium bowl. Place flour in another medium bowl; season with salt and pepper. Working in batches, toss onion rings in flour; shake off excess. Dip in buttermilk, letting excess drip back into bowl. Return to flour and toss to coat again; shake off excess.

Heat 60ml butter in a large skillet over medium, stirring occasionally, until lightly browned and foaming. Add half of onion and cook, turning once, until golden brown and crisp, 8–10 minutes. Transfer to paper towels with tongs; season with salt and pepper. Repeat with remaining butter and onion.
