Directions

Prep the Onions: Peel and slice the onions into ½-inch thick rings. Gently separate the rings, keeping any smaller inner rings for another dish. Soak the rings in buttermilk with 1 tsp salt for at least 30 minutes, or refrigerate overnight for a deeper flavor.
Prepare the Coating Stations: Set up a three-bowl breading station:
- Bowl 1: Combine flour with a pinch of salt and pepper.
- Bowl 2: Whisk eggs with a splash of milk or water.
- Bowl 3: Mix panko breadcrumbs with garlic powder, paprika, black pepper, salt, and optional cayenne.
Preheat Your Oven: Preheat the oven to 425°F (220°C). Line two baking sheets with parchment paper or lightly oiled foil. For extra crispiness, you can use a wire rack.
Bread the Onion Rings: One by one, dip each onion ring in the flour, then the egg wash, and finally coat with the panko mixture. Arrange the breaded onion rings on the baking sheet and lightly spray them with olive oil or non-stick spray.
Bake to Golden Perfection: Bake the onion rings for 10 minutes, then flip each ring and bake for another 10–15 minutes until they are golden brown and crispy.
Serve Hot: Let the rings cool slightly, then serve with your favorite dips such as ranch, garlic aioli, or spicy mayo.

Variations

Vegan Option: Use a plant-based milk for the buttermilk, and replace the eggs with a flaxseed egg substitute or another egg replacer.
Spicy Onion Rings: Add extra cayenne pepper or chili powder to the breadcrumb coating for a spicy kick.
Cheesy Variation: Mix grated Parmesan or nutritional yeast into the breadcrumb coating for a cheesy flavor.

Storage/Reheating

Storage: Store any leftover onion rings in an airtight container in the refrigerator for up to 2–3 days.
Reheating: To maintain their crispiness, reheat the onion rings in a preheated oven at 375°F (190°C) for 5–10 minutes, or until heated through and crispy again. You can also reheat them in an air fryer for the best results.
