Instructions

1. 1

   Heat the oven

   Preheat the oven to 230°C. Line two baking sheets with baking paper and set them aside.

2. 2

   Mix the flour

   In a small bowl, combine the flour, smoked paprika, paprika, 1 teaspoon of the salt, the pepper and garlic powder.

3. 3

   Whisk the batter

   In another bowl or shallow dish, whisk the buttermilk and eggs together. Add half of the flour mixture and beat until smooth and thickened.

4. 4

   Season the crumbs

   In a separate bowl, combine the breadcrumbs with the remaining teaspoon of salt.

5. 5

   Coat the rings

   Lightly dredge the onion rings in the flour mixture, then dip them into the buttermilk batter. Let excess batter drain off before coating them in breadcrumbs. For a thicker coating, chill the coated rings for 1 hour, then repeat this coating step.

6. 6

   Arrange on trays

   Place the rings in a single layer on the prepared baking sheets, leaving space between them. Smaller rings can sit inside larger ones if needed.

7. 7

   Spray the coating

   Spray the onion rings generously with cooking spray.

8. 8

   Bake until crisp

   Bake for 20–30 minutes. Halfway through, turn each ring over and spray it with cooking spray to help it brown and crisp evenly.

What are onion rings?

Onion rings are a familiar American side, made by coating onion slices and cooking them until crisp. This version uses a seasoned breadcrumb crust and the oven rather than a deep fryer.

Sweet yellow onions bring a mellow flavour, while the paprika and garlic add savoury warmth. The layered coating helps give the rings a crunchy outside and tender centre.

Nutrition and macros by portion

The nutrition label shows one serving as written: 388 calories, 15g protein, 67g carbs, 5g fat.

The breadcrumbs and flour provide most of the carbohydrates, while the eggs and buttermilk contribute protein and the cooking spray adds some fat. Pair a serving with a generous salad or other vegetables for a more balanced plate.

Choosing and slicing the onions

Sweet onions: Large yellow sweet onions give you broad rings with a mild flavour. Separate the slices gently so they stay intact.

Even slices: Aim for slices 6–12 mm thick. Rings of similar thickness are more likely to soften at the same rate.

Building the coating

Flour layer: The seasoned flour gives the wet batter something to cling to. Shake off excess before dipping so the coating does not become patchy.

Buttermilk batter: Whisking half the flour mixture into the buttermilk and eggs makes a thicker dip. Let extra batter drip off before moving each ring to the crumbs.

Breadcrumb finish: Press the crumbs gently onto the wet surface so they adhere. Chilling for 1 hour and repeating the coating step gives a thicker crust.

Getting an even bake

Room to brown: Arrange the rings in one layer with gaps between them. Crowded rings can soften where they touch instead of crisping evenly.

Turn halfway: Flip each ring midway through baking and spray the newly exposed side. Start checking at 20 minutes; the coating should look golden and crisp.

Seasoning and texture

Smoked paprika: This brings a gentle smoky note, while regular paprika adds a milder pepper flavour. Garlic powder rounds out the savoury seasoning.

Salt distribution: Some salt goes into the flour mixture and the rest seasons the breadcrumbs. Keep the coatings in their separate bowls so each layer gets seasoned.

What to serve with them

Sauces: Serve the rings hot with a dip such as mayonnaise, ketchup or a tangy yoghurt sauce. Put the sauce on the side to keep the crust crisp.

A fuller plate: Pair them with a salad or a simple vegetable side. Their crisp coating also works well alongside a sandwich or burger.

Recipe notes & tips

• Set up the flour, batter and breadcrumbs in separate shallow dishes for easier coating.
• Let excess batter drip off each ring before coating it in breadcrumbs.
• Leave gaps between the rings so hot air can circulate around them.
• Spray the rings on both sides, including after turning them halfway through.
• Check the rings from 20 minutes onwards, as smaller or thinner ones may finish sooner.

Variations

• Add cayenne: Mix a pinch into the flour for a hotter coating.
• Use panko: Swap in panko breadcrumbs for a coarser, crunchier crust.
• Try extra herbs: Add dried oregano to the flour mixture for an earthy note.
• Make them cheesier: Mix finely grated Parmesan through the breadcrumbs.
• Serve with a dip: Offer a tangy yoghurt or mustard sauce on the side.

Common mistakes to avoid

• Crowding the trays: Overlapping rings brown less evenly; leave space between them.
• Leaving on excess batter: A thick wet layer can make crumbs slide off; let each ring drain before breading.
• Skipping the flip: The undersides may brown unevenly; turn every ring halfway through baking.
• Using too little spray: Dry patches may stay pale; spray the coated rings generously.
• Baking by time alone: Rings can vary in size; check for a crisp, golden coating from 20 minutes.

How to store

Refrigerate leftover onion rings in an airtight container for up to 3 days. Reheat in an oven or air fryer until hot and crisp; microwaving can soften the coating.
