Instructions

1. 1

   Slice the onion

   Cut the onion into rings about 1.3 cm (½ inch) thick.

2. 2

   Make the buttermilk

   Stir the almond milk and vinegar together, then pour the mixture over the onion rings in a shallow dish.

3. 3

   Soak the rings

   Cover the dish and refrigerate for at least 1 hour.

4. 4

   Prepare the batter

   After soaking, measure out 240 ml (1 cup) of the almond milk mixture and combine it with the flour and cornflour to make a batter.

5. 5

   Mix the coating

   In another small dish, combine the remaining ingredients for the breadcrumb coating.

6. 6

   Dip the rings

   Dip each onion ring into the batter, then shake off any excess.

7. 7

   Coat with crumbs

   Set each battered ring in the breadcrumb mixture and use a separate spoon to cover it completely.

8. 8

   Arrange on tray

What are onion rings?

Onion rings are a familiar American-style side or snack: slices of onion are coated in batter or crumbs, then cooked until crisp. This version keeps the classic sweet onion and crunchy coating, but uses the oven or an air fryer instead of deep-frying.

The almond milk and vinegar stand in for buttermilk, while panko gives the outside a light, coarse crunch. Sweet varieties such as Vidalia or Walla Walla suit the mild, tangy coating particularly well.

Nutrition and macros by portion

The nutrition label shows one serving as written: 300 calories, 9g protein, 61g carbs, 4g fat.

The flour, panko and onion supply most of the carbohydrates, while the almond milk contributes relatively little fat if it is unsweetened. There is no major protein-rich ingredient, so the rings are best served with a protein source such as beans or a veggie burger and a salad or other vegetables to balance the plate.

Why soak the onion?

Tangy soak: the vinegar stirred into almond milk creates the recipe’s buttermilk-style dip. Letting the rings sit in it gives the coating a moist surface to cling to.

Time: the method calls for at least 1 hour in the fridge. The stated total time of 60 minutes does not include any extra soaking time beyond that hour.

Building the coating

Batter: flour and cornflour thicken a measured cup of the soaking liquid into a coating that helps the crumbs adhere. Shake off excess so the rings do not end up with a heavy layer.

Crumbs: panko, cornmeal, nutritional yeast and seasonings create a textured, savoury outer layer. Use a separate spoon for the crumb mixture to keep it from clumping with wet batter.

How to get a crisp finish

Spacing: arrange the rings on the parchment-lined sheet with room around them so hot air can reach the coating. If they are crowded, bake them in batches.

Turning: flip them after the first 20 minutes, then bake for another 10 minutes. Look for a dry, golden coating; the air-fryer option takes 10–15 minutes at 180°C.

Choosing the onion

Sweet onion: a large Vidalia or Walla Walla is the specified choice, with broad rings that are easy to coat. Slice evenly so the rings cook at a similar pace.

Ring size: the method specifies slices about 1.3 cm thick. Separate the slices into rings before dipping them.

What to serve alongside

Dipping sauce: serve the rings with your preferred dip, as the recipe suggests. A simple tomato-based sauce or a creamy dip both work well with the savoury crumb coating.

For a more substantial plate, add a salad or serve them alongside a sandwich or veggie burger. Put them on the table soon after cooking for the best crunch.

Recipe notes & tips

• Keep the soaking dish covered in the fridge for at least 1 hour.
• Measure 240 ml (1 cup) of the soaking liquid for the batter after the rings have soaked.
• Use a spoon to scatter crumbs over each ring rather than handling the crumb mixture with batter-covered fingers.
• Line the baking sheet with parchment to make the coated rings easier to lift off.
• Turn the rings carefully after 20 minutes so the coating stays in place.
• Check the rings towards the end of cooking, as ovens and air fryers can brown at different rates.

Variations

• Add smoked paprika: mix a little into the crumb coating for a smoky note.
• Increase the heat: add more cayenne to the crumbs for a spicier finish.
• Use a different dip: serve with a tangy tomato sauce or a creamy dip of your choice.
• Try another sweet onion: use a large sweet onion in place of the named varieties.
• Air-fry the rings: cook at 180°C for 10–15 minutes, as the recipe’s alternative method directs.

Common mistakes to avoid

• Skipping the soak: the recipe relies on at least 1 hour in the fridge, so allow that time before coating.
• Using all the soaking liquid: measure out just 240 ml (1 cup) for the batter.
• Leaving thick batter on the rings: shake off the excess before adding the crumbs.
• Handling crumbs with wet fingers: use a separate spoon to cover each ring and keep the coating loose.
• Crowding the baking sheet: leave space between rings or bake them in batches.
• Forgetting to turn the rings: flip them after the first 20 minutes for the remaining 10 minutes of oven baking.

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; microwaving tends to soften the coating.
