The healthy baked onion rings are crispy and light without the greasy aftertaste of deep-fried versions. This low-fat method uses a combination of panko, whole wheat breadcrumbs and crushed cornflakes to give the rings a satisfying crunch while keeping the oil to a minimum.
Baked Onion Rings
Perfect as a snack, appetizer or a side to a juicy burger, these baked onion rings deliver golden, crunchy results with far less fat than frying. The technique is simple: soak the rings in low-fat buttermilk, coat them in a crisp breadcrumb mixture, arrange them on a sheet and bake until golden. The result is light, crunchy onion rings that are easy to make at home.
Why this method works
Soaking the onion rings in buttermilk softens their bite and helps the coating adhere. Using a mix of panko, whole wheat breadcrumbs and crushed cornflakes makes for extra texture and crispness without adding deep-fried oil. Baking at a high temperature and giving the rings a light spray of olive oil helps them brown and crisp up in the oven.
Ingredients
- 1 medium onion, sliced into 1/4 inch rings
- 2 1/4 cups low-fat buttermilk
- 1/2 cup panko bread crumbs
- 1/4 cup Italian seasoned whole wheat bread crumbs
- 1/4 cup crushed corn flake crumbs (or pulse regular corn flakes in a food processor)
- Salt, to taste
- Olive oil baking spray (or a light mist of oil)
Instructions
- Place the sliced onion rings in a shallow dish and pour the low-fat buttermilk over them. Refrigerate and let the rings soak for 1–2 hours. This step tenderizes the onion and helps the coating stick.
- Preheat the oven to 450°F (232°C). Line a baking sheet with parchment paper or foil for easy cleanup.
- Combine the panko, whole wheat breadcrumbs and crushed cornflake crumbs in a bowl. Season the mixture with salt. For best results, split the crumbs in half and use only part of the mixture for the first batch—reserving the rest prevents clumping and helps the crumbs coat more evenly.
- Working in batches, dip each soaked onion ring into the crumb mixture and press gently to coat well. Using tongs to handle the rings helps keep the coating intact and avoids getting the breading greasy from your fingers.
- Arrange the coated rings in a single layer on the prepared baking sheet(s), making sure they don’t overlap.
- Lightly spray the tops of the rings with olive oil baking spray (or a light mist from an oil mister). This encourages even browning in the oven.
- Bake for about 12 minutes, or until the rings are golden brown and crisp. Oven times can vary slightly, so check toward the end of cooking and rotate the pans if needed for even color.
- Serve immediately for the best crunch.
Yield, Prep & Cook Time
- Yield: 2 servings (adjustable)
- Serving size: 1/2 of the batch
- Prep time: 10 minutes (plus 1–2 hours soaking)
- Cook time: 12 minutes
- Total time: about 22 minutes active + soaking time
Tips and variations
- If you don’t have crushed cornflakes, pulse regular corn flakes in a food processor until crumb-sized.
- Do the breading in two batches and reserve some crumb mixture to prevent clumping and improve adhesion.
- Use an oil mister for a light, even spray. If you prefer, brush the rings lightly with oil instead.
- For extra flavor, add a pinch of smoked paprika, garlic powder or cayenne to the crumb mix.
- Try a gluten-free version by substituting gluten-free panko and cereal crumbs.
Storage and reheating
Leftover baked onion rings are best eaten fresh. If storing, keep them in an airtight container in the refrigerator for up to 1–2 days. Re-crisp them in a preheated 375°F (190°C) oven for 6–8 minutes, watching carefully so they don’t over-brown. Microwaving will soften the coating.
Notes
After preparing and baking, there may be leftover crumb mixture and buttermilk. The original recipe author noted that 2/3 of the crumb mix and about 2 cups of buttermilk remained and those amounts were deducted from the nutritional calculations. Using only part of the crumb mixture for the first batch helps with even coating and prevents waste.
