• 454 g (1 pound)sweet onions, such as Vidalia, Maui or Walla Walla
• 80 g (⅔ cup)plain flour
• 2 tablespoonscornflour
• 240 ml (1 cup)cold unsweetened dairy-free milk alternative
• 1 teaspoonapple cider vinegar or white vinegar
• 60 g (1 cup)panko breadcrumbs
• 1 teaspoonsalt
• 10 ml (2 teaspoons)olive oil
• as neededcooking spray

Instructions

1. 1

   Slice the onions

   Cut the onions into rings 1.3–1.9 cm (½–¾ inch) thick. Separate the rings and place the larger ones in a bowl; reserve the smaller inner rings for another recipe.

2. 2

   Heat the oven

   Preheat the oven to 230°C (450°F). Line a rimmed baking sheet with parchment paper and coat the parchment with cooking spray.

3. 3

   Mix the batter

   Whisk the flour and cornflour together in a wide bowl. Gradually whisk in the dairy-free milk until smooth, then whisk in the vinegar.

4. 4

   Prepare the crumbs

   Stir the panko and salt together in a second wide bowl. Drizzle in the oil and gently mix with your fingers to coat the crumbs.

5. 5

   Set up the coating

   Arrange the onions, batter, breadcrumbs and prepared baking sheet in that order.

6. 6

   Coat the rings

   Dip an onion ring in the batter and let excess drip off. Move it to the crumbs and use your other hand to sprinkle crumbs over it until fully coated. Transfer it carefully to the baking sheet and repeat with the remaining rings.

7. 7

   Spray the rings

   When all the rings are on the sheet, lightly spray them with cooking spray.

8. 8

   Bake until crisp

   Bake for 8 minutes, gently flip the rings, then bake for another 6 minutes, until golden brown and crisp.

9. 9

   Serve straight away

   Serve the onion rings immediately.

What are onion rings?

Onion rings are a familiar American diner-style side: slices of onion are coated and cooked until the outside is crisp and the onion inside is tender. This version uses the oven rather than deep-frying.

Sweet onions bring a mild flavour, while a thin batter helps the coating adhere and keeps the centres juicy. Panko adds a rough, crisp outer layer.

Nutrition and macros by portion

The nutrition label shows one serving as written: 260 calories, 7g protein, 47g carbs, 5g fat.

The flour and panko provide most of the carbohydrates, while the olive oil contributes fat; the small amount of protein comes mainly from the flour and breadcrumbs. Serve a portion with vegetables and a protein-rich main to round out the plate.

Choosing the onions

Sweet onions: Vidalia, Maui or Walla Walla varieties suit this recipe, but any large sweet onion can work. Cut the slices evenly so the rings cook at a similar rate.

Ring size: Separate the slices gently and use the larger rings for coating. The small inner rings can be saved for another dish.

Getting an even coating

Batter: Whisk in the dairy-free milk gradually to avoid lumps, then add the vinegar. The mixture should be smooth enough to cling to an onion ring without forming a thick layer.

Crumbs: Use one hand for the wet batter and the other for the panko. This helps keep the crumbs from clumping together as you work through the batch.

Keeping the coating crisp

Panko: These larger, airy breadcrumbs make a crisp coating. Mix them gently with the oil so they are lightly coated rather than compressed.

Spacing: Arrange the rings in a single layer on the baking sheet. A light spray over the coated rings helps the surface brown as it bakes.

Watching the bake

First side: Bake for 8 minutes before turning the rings gently. The coating should be set enough to handle carefully.

Second side: Bake for 6 more minutes, looking for a golden colour and crisp crumbs. Serve soon after baking, while the coating is at its best.

What to serve with them

Dips: Serve the rings with a dairy-free mayonnaise, ketchup or another dip you enjoy. Keep the dip on the side so the coating stays crisp.

Meal pairing: Add them to a plant-based burger or serve them alongside a salad and a source of protein for a more complete plate.

Recipe notes & tips

• Choose onions of similar size so the rings bake more evenly.
• Whisk the milk into the dry ingredients gradually for a smoother batter.
• Let excess batter drip off before coating each ring with panko.
• Keep one hand for batter and the other for breadcrumbs to avoid coating your fingers.
• Leave space between the rings so they bake rather than steam.
• Serve immediately for the crispest texture.

Variations

• Add spice: Mix paprika or black pepper into the panko.
• Change the herbs: Stir dried herbs into the crumb mixture for an aromatic coating.
• Make them gluten-free: Use gluten-free plain flour and panko-style breadcrumbs.
• Switch the milk: Choose another cold, unsweetened dairy-free milk alternative.
• Serve with dip: Pair the rings with a dairy-free mayonnaise or ketchup.

Common mistakes to avoid

• Uneven slices: Cut the onion rings to a similar thickness so they cook at roughly the same rate.
• Lumpy batter: Add the milk gradually while whisking the flour and cornflour.
• Wet crumbs: Let excess batter drip off before moving each ring to the panko.
• Crowded tray: Arrange the rings in one layer with room between them.
• Rough flipping: Turn the rings gently so the coating stays attached.
• Waiting too long: Serve soon after baking, as the coating softens as it sits.

How to store

Store cooled leftovers in an airtight container in the fridge for up to 3 days. Reheat in an oven or air fryer until hot and crisp; the microwave will soften the coating.
