Today I’ll show you how to make easy, crunchy baked onion rings. These panko-coated onion rings are simple to prepare, satisfyingly crispy, and a lighter alternative to traditional deep-fried rings without sacrificing flavor.
Baked Onion Rings
If you want a side that’s light, crispy, and comfortingly nostalgic, baked onion rings are a great choice. Traditionally a deep-fried diner favorite, onion rings can be made at home with far less fuss and fewer calories when baked. You still get the satisfying crunch and rich flavor—minus the oil bath and cleanup.
I’ve made traditional deep-fried onion rings before, and while delicious, deep frying a single batch can be a hassle. Baking is simpler and cleaner, and it produces consistently crisp results when done right.
If your goal is everyday health food, these aren’t it—there’s panko, crushed potato chips, and oil in the coating—but baking reduces the amount of oil used compared with deep frying and makes for a delicious treat you can enjoy more often.
Why bake instead of fry?
Roasting or baking vegetables helps concentrate their natural sugars and intensifies flavor. For onion rings, baking can produce excellent caramelization and a crisp exterior without the greasiness that can come from deep frying. This method also requires less active attention and avoids the safety and cleanup challenges of hot oil.
Baked onion rings keep a crunchy texture when coated properly and spaced in a single layer on a hot sheet. You’ll be surprised how close the oven method gets to the mouthfeel of deep-fried versions.
Baked Onion Rings Shopping List
These baked onion rings use a few straightforward ingredients. The breading mixture can be seasoned heavily to deliver flavor, since panko is typically unseasoned on its own.
- 2 large sweet onions (Vidalia or Walla Walla are ideal)
- 2–3 cups buttermilk
- 1 egg (or 2 egg whites if you prefer)
- Flour for dredging (about 3/4 cup)
- 2 cups panko breadcrumbs
- 10 saltine crackers (or similar)
- 3 large handfuls kettle-cooked potato chips
- Salt and white or black pepper
- Smoked paprika and garlic powder
- Cooking spray and 1/2 cup avocado or vegetable oil
How to bread onion rings
Soak the rings
Slice a large sweet onion into 1/3 to 1/2-inch rings. Reserve any small center pieces for another use. Place the rings in a large container or resealable bag and cover with 2–3 cups of buttermilk along with 1/2 teaspoon salt, 1/8 teaspoon cayenne, and 1/2 teaspoon seasoned salt. Refrigerate and let soak for several hours or overnight—this softens the onion slightly and helps the coating adhere. When ready, drain the rings and reserve the buttermilk.
Mix the breading
Pulse the saltines and potato chips in a food processor or crush them in a sealed bag until finely broken. Combine those crumbs with 1/2 cup panko breadcrumbs. In a separate bowl, whisk the reserved buttermilk with one beaten egg to make the wet mixture. Put 3/4 cup flour in another bowl for dredging.
How to make crispy baked onion rings
- ONION SIZES MATTER – Use sweet onions and slice them about 1/2 inch thick. Thinner slices tend to fall apart; thicker slices take too long to cook.
- SOAK THE ONIONS – The buttermilk soak improves texture and flavor—don’t skip it.
- PREHEAT A HOT SHEET – Preheat the oven to 375–425°F (the recipe below uses 375°F to allow even baking) and place a rimmed baking sheet with a thin layer of oil in the oven so the surface is hot when the rings hit it; this jump-starts crisping.
- SINGLE LAYER ONLY – Arrange the breaded rings in a single layer with a little space between them so hot air can circulate. Crowding the pan will cause soggy spots.
- FLIP HALFWAY – Bake until golden on one side, then flip and bake on the other side so both sides brown evenly. Total baking time varies by oven—monitor closely.
How to store and reheat leftovers
These are best eaten fresh. If you have leftovers, store them in a container lined with paper towels to absorb excess moisture. Reheat in a preheated oven or air fryer for best results—about 400°F for 4–6 minutes should restore the crispiness. You can also freeze breaded rings on a tray, then transfer to a freezer bag and bake straight from frozen when you want them.
Are oven-baked onion rings healthy?
Baked onion rings are lighter than deep-fried versions, but they are still an indulgence: the coating contains panko and crushed chips, and oil is used for baking. Enjoy them as an occasional treat rather than a daily vegetable serving.

20 minutes
7 minutes (per side varies)
about 27 minutes
Ingredients
- 1–2 large Vidalia or sweet onions, sliced into ½-inch rings
- 2–3 cups buttermilk
- ½ teaspoon salt
- ½ teaspoon seasoned salt
- ⅛ teaspoon cayenne pepper (optional)
- 1 egg
- 10 saltine crackers, crushed
- 3 large handfuls kettle-cooked potato chips, crushed
- ½ cup panko breadcrumbs
- ¾ cup flour
- ½ cup oil (for heating on the baking sheet) plus cooking spray
Instructions
- Soak the sliced onions in buttermilk with salt, seasoned salt, and cayenne for at least 2 hours or overnight in the refrigerator.
- Drain the onions, reserving the buttermilk. Whisk one egg into the reserved buttermilk. Place flour in a separate bowl for dredging. Crush the saltines and potato chips and combine with panko to form the crumb mixture.
- Preheat the oven to 375°F (or up to 425°F for a faster, crisper finish). Add a thin layer of oil to a rimmed baking sheet and place it in the oven to heat.
- To bread each ring: dredge in flour, dip into the buttermilk-and-egg mixture, then press into the chip/panko mixture. Arrange breaded rings in a single layer on a clean platter.
- Carefully place the coated rings on the hot baking sheet and bake until golden on one side, about 5–7 minutes depending on oven and thickness. Watch closely to avoid burning.
- Flip each ring and bake until golden and crisp on the other side. Remove from oven and serve immediately.
