Ingredient Notes

Best Onions to Use

Sweet onions like Vidalia onions work best because they become tender and slightly sweet when cooked.

Sourdough Bread Crumbs

Use homemade sourdough bread crumbs for the best texture. Slightly stale sourdough bread works perfectly.

Liquid

Using buttermilk or milk instead of water will make the coating richer, and more tender while adding flavor

Air Fryer Instructions

• Spray onion rings lightly with oil
• Air fry at 375°F
• Cook for 10–12 minutes
• Flip halfway through cooking

Oven-Baked Instructions

Bake at 425°F on a parchment-lined baking sheet for 18–22 minutes, flipping halfway through.

Best Dipping Sauces

These onion rings pair perfectly with:

• Ranch dressing
• Garlic aioli
• Fry sauce
• Spicy mayo
• BBQ sauce
• Honey mustard

Frequently Asked Questions

Can I make these ahead of time?

You can bread the onion rings ahead of time and refrigerate until ready to fry.

Can I freeze onion rings?

Yes. Freeze breaded uncooked onion rings on a baking sheet until solid, then transfer to a freezer-safe bag.

Can I use store-bought breadcrumbs?

Yes, but homemade sourdough bread crumbs give the best flavor and texture.

Why won’t my coating stick?

Make sure the onion rings are fully coated in flour first before dipping into the egg mixture.
