Step‑by‑Step Instructions for Crispy Baked Parmesan Onion Rings
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). While the oven heats, line a baking sheet with parchment paper; this will prevent the Parmesan onion rings from sticking and ensure they bake evenly. Use this time to gather your ingredients, creating a cozy cooking environment.
Step 2: Prepare the Onions
Next, peel and slice two medium white onions into uniform ¼-inch thick rings. This thickness is key for even cooking—too thin and they may burn, too thick and they won’t crisp up. Once sliced, arrange them on a cutting board, ready for their cheesy transformation into delicious Parmesan onion rings.
Step 3: Create Cheese Molds
Spoon 1 tablespoon of shredded parmesan onto the parchment-lined baking sheet, forming small circles—these will serve as the base for each onion ring. The cheese should be finely shredded to ensure it melts seamlessly. Keep your circles about the same size as the onion rings for even coating, making sure there’s enough space between each.
Step 4: Assemble Rings
Now, gently place an onion ring on each cheese circle, ensuring it sits flat. Top each ring with another tablespoon of shredded parmesan, covering the onion completely. This double layer of cheese will create that irresistible crunch once baked, so make sure to distribute the parmesan evenly for maximum deliciousness.
Step 5: Press and Season
Lightly press down on each assembled onion ring to help the cheese adhere, ensuring a charmingly crunchy texture. Next, season the tops generously with salt, garlic powder, paprika, and Italian seasoning if desired. This will elevate the flavor of your Parmesan onion rings, infusing them with savory goodness.
Step 6: Bake
Carefully place the baking sheet in the preheated oven and allow the Parmesan onion rings to bake for 15–20 minutes. Keep a close eye on them as they cook, watching for a golden-brown color. The cheese will melt and crisp up beautifully, transforming your ring assembly into a crunchy, cheese-coated delight.
Step 7: Cool
Once perfectly baked, remove the tray from the oven and let the Parmesan onion rings cool on the baking sheet for 10–15 minutes. This cooling period is crucial for enhancing crispiness, giving you that satisfying crunch. Once cooled, they’re ready to serve, highlighting your culinary prowess!

Expert Tips for Perfect Parmesan Onion Rings
-
Slice Evenly: Always cut the onions into uniform ¼-inch rings. Unequal sizes lead to inconsistently cooked rings, some may burn while others stay soggy.
-
Finely Shredded Cheese: Use finely shredded parmesan for the best coating. Coarse shreds may not stick well and won’t give that desired crunch in your Parmesan onion rings.
-
Watch the Bake: Ovens vary; keep an eye on your onion rings during the last few minutes of baking to prevent overcooking. Note that they can turn from golden to burnt quickly!
-
Cooldown Time: Allowing the rings to cool on the baking sheet helps achieve that maximum crunch. Don’t rush this step for the best results.

Parmesan Onion Rings Recipe FAQs
