1: Preheat & Prep: Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper to prevent sticking.

2: Slice the Onion: Using a knife or mandolin, slice the large white onion into thin rings (about ¼-inch rounds). For safety, use a cut-resistant glove if using a mandolin.

3: Layer the Cheese & Onion: Sprinkle a generous layer of shredded parmesan cheese evenly onto the parchment-lined baking sheet.

Air Fryer Variation – Crispy Parmesan Onion Ring Chips

If you prefer to make these crispy onion ring chips in the air fryer, follow these simple steps:

1: Preheat the Air Fryer: Set your air fryer to 375°F (190°C) and line the basket with parchment paper or a perforated air fryer liner to prevent sticking.

2: Prepare the Onion Slices: Slice a large white onion into thin rings (about ¼-inch rounds) using a knife or mandolin.

3: Layer the Cheese & Onion: Sprinkle shredded parmesan cheese directly onto the parchment paper in the air fryer basket. Arrange the onion slices in a single layer on top of the cheese, ensuring they don’t overlap.

4: Season & Add More Cheese: Sprinkle the ranch seasoning (or your preferred seasoning), then top with another layer of parmesan cheese for extra crispiness.

5: Air Fry to Perfection: Cook at 375°F for 8-10 minutes, checking around minute 7 to ensure they aren’t over-browning. Cook until the cheese is melted and turns golden brown and crispy.

6: Cool & Slice: Let the onion crisps cool for a few minutes before carefully slicing them into chips or breaking them apart into bite-sized pieces.

7: Enjoy! Serve immediately with your favorite dip or eat them as a low-carb, crunchy snack straight from the basket!

Expert Tips

1️⃣ Use Fresh, Firm Onions – Choose large white onions with a firm texture for the best crispy chips. Softer onions can release too much moisture, making them soggy.

2️⃣ Slice Evenly for Consistent Crispiness – Use a sharp knife or mandolin to slice ¼-inch rounds evenly. This ensures they cook at the same rate. Wear a cut-resistant glove for safety when using a mandolin.

3️⃣ Pat Dry for Extra Crispiness – Before layering, pat the onion slices dry with a paper towel. This removes excess moisture and helps them crisp up better.

4️⃣ Shred Your Own Parmesan – Pre-shredded parmesan contains anti-caking agents that can prevent proper melting. Freshly shredded parmesan creates a more even, crispy texture.

5️⃣ Season Between Layers – To get maximum flavor, sprinkle seasonings like garlic powder, smoked paprika, or ranch seasoning between the layers of parmesan cheese and onions.

6️⃣ Bake on Parchment Paper – This prevents sticking and allows the cheese to crisp up properly without burning. A silicone baking mat also works well.

7️⃣ Let Them Cool Completely – Once out of the oven, let the chips cool on the pan for 5-10 minutes. This helps them set and get that perfect crunch.

8️⃣ Best Storage Method – Store leftover onion ring chips in an airtight container at room temperature for up to 2 days or in the fridge for up to 5 days. Use parchment paper between layers to prevent sticking.

9️⃣ Reheating for Crispiness –
🔥 Oven: Preheat to 350°F and bake for 5 minutes.
🔥 Air Fryer: Reheat at 350°F for 3-4 minutes.
🔥 Skillet: Heat over medium heat for a quick crisp refresh.
(⚠ Avoid microwaving, as it makes them soft.)

🔟 Experiment with Cheese Blends – While parmesan is ideal, you can mix in asiago, pecorino romano, or cheddarfor different flavors. Just keep the parmesan as the base for the best crisp!

Trouble Shooting Guide

1️⃣ Chips Turn Out Soggy
❌ Problem: Too much moisture from the onions or cheese.
✅ Fix:

• Pat the onion slices dry with a paper towel before assembling.
• Use freshly shredded parmesan instead of pre-shredded (which contains anti-caking agents that prevent crisping).
• Let them cool completely after baking to allow them to set properly.

2️⃣ Cheese Burns Before Onions Are Done
❌ Problem: Oven temperature is too high or onions are too thick.
✅ Fix:

• Keep the oven at 400°F (if your oven runs hot, lower it to 375°F).
• Slice onions into even ¼-inch rounds so they cook at the same rate.
• Use parchment paper or a silicone baking mat to prevent over-browning.

3️⃣ Chips Stick to the Pan
❌ Problem: No parchment paper or not enough cheese underneath.
✅ Fix:

• Always line your baking sheet with parchment paper.
• Sprinkle a good base layer of parmesan before placing the onions so they don’t stick.

4️⃣ Chips Don’t Get Crispy Enough
❌ Problem: Not enough cheese or baked at the wrong temp.
✅ Fix:

• Use enough parmesan to form a solid base for crisping.
• Make sure to bake in a single layer, giving space between the onions.
• If they are still soft, bake for 2-3 extra minutes or pop them in the air fryer for 2 minutes at 375°F.

5️⃣ Seasoning Falls Off
❌ Problem: Sprinkling seasoning only on top.
✅ Fix:

• Layer the seasoning between the cheese and onions for even flavor.
• Lightly press seasonings into the parmesan before baking.

6️⃣ Chips Don’t Reheat Well
❌ Problem: Using the microwave.
✅ Fix:

• Best method: Reheat in the air fryer (350°F for 3-4 min) or oven (350°F for 5 min) to restore crispiness.
• If using a skillet, heat on medium-low without oil until crispy again.

7️⃣ Onions Separate from the Cheese
❌ Problem: Not enough cheese to hold them together.
✅ Fix:

• Make sure you have a layer of cheese under and over the onion slices.
• Let them cool completely before handling to allow them to set properly.

8️⃣ Too Salty
❌ Problem: Parmesan and seasoning blend both contain salt.
✅ Fix:

• Use unsalted or low-sodium parmesan if needed.
• If using ranch seasoning, cut back on added salt.

9️⃣ Onions Are Too Strong in Flavor
❌ Problem: Raw white onions can have a sharp taste.
✅ Fix:

• Use sweet onions instead of white onions for a milder flavor.
• Soak onion slices in cold water for 10 minutes, then pat dry before baking.

🔟 Not Enough Crunch?
❌ Problem: Cheese blend isn’t crispy enough.
✅ Fix:

• Stick with 100% parmesan as the base cheese.
• If adding cheddar, asiago, or romano, use a 50/50 blend to keep crispiness.
• Let them cool on a wire rack for extra airflow.
