Crispy Onion Rings

These crispy oven-baked onion rings offer all the satisfying crunch of a classic takeaway side dish without the need for a deep fat fryer. By using a buttermilk soak and a seasoned breadcrumb coating, the onions remain tender on the inside while achieving a beautiful golden exterior. They are a fantastic vegetarian alternative to heavier snacks, providing a lighter way to enjoy a savoury favourite at home.

Ideal for serving alongside a homemade veggie burger or as a crowd-pleasing party snack, this recipe is simple to prepare and easy to clean up. Using a baking tray lined with foil ensures the rings crisp up evenly in a hot oven. Serve them immediately with your favourite dipping sauce for a comforting treat that everyone will enjoy.

Ingredients for Crispy Onion Rings

  • 1 large sweet, vidalia or maui onion

  • 180ml buttermilk

  • 2 teaspoons salt, divided

  • 350ml plain breadcrumbs (i used whole wheat)

  • Canola oil spray

Preheat oven to 425 degrees.

Cut onions into 1/2 inch rounds and separate into rings.

Whisk buttermilk and 1 teaspoon salt into a bowl.

Place breadcrumbs in a separate bowl and add another tsp salt.

Dip onion rings in buttermilk mixture and then dredge in breadcrumb mixture covering both sides of the onion completely (make sure to use one hand for wet dipping and one hand for dry dipping so you don't get soggy, clumpy breadcrumbs and messy fingers).

Place onion rings on a oil sprayed baking sheet (I lined the biscuit sheet with foil for easier clean up).

Lightly spray the onion rings with oil cooking spray.

Bake for 20-25 minutes, turning once halfway through, until lightly browned.

Serve.
