Did you know that onion rings date back to the early 1900s? While their exact origins are debated, an old 1910 cookbook featured a recipe for battered, fried onions, making them a timeless classic. This version, however, gives them a modern twist—crispy, cheesy, and baked to perfection!
So, whether you’re hosting a party, craving a quick snack, or just want something new to try, these Onion Ring Chips are a must-make! Let’s get baking!

Recipe Yield: About 2 servings
INGREDIENTS
2 medium yellow or sweet onions, very thinly sliced into rings (about 1/4-inch thick)
1 ½ cups shredded Parmesan cheese (or sharp cheddar for a richer flavor)
3/4 tbsp olive oil
Optional seasonings for extra flavor:
½ tsp garlic powder
½ tsp paprika
Salt & black pepper, to taste
INSTRUCTIONS
1. Preheat oven: Set to 400°F (200°C). Line a baking sheet with parchment paper or a silicone baking mat to prevent sticking.
2. Prep the onions: Thinly slice the onions into even round slices, about 1/4-inch thick, keeping the layers intact. Blot them dry with a paper towel to remove excess moisture. Lightly brush each slice with olive oil. Then, sprinkle with garlic powder, paprika, salt, and pepper for extra flavor.
3. Arrange on the baking sheet: Lay the onion rings flat with space between each—no overlapping!
4. Add the cheese: Generously sprinkle Parmesan (or cheddar) inside and around each onion ring, ensuring full coverage for the ultimate crunch.
5. Bake: Place in the oven for 15-18 minutes, or until the cheese is bubbling, golden brown, and crisp around the edges.
6. Cool & crisp up: Let them cool on the tray for 5 minutes before carefully lifting them off. This helps them crisp up even more!
7. Serve & enjoy: These crispy onion ring chips are delicious as-is or with your favorite dip—think ranch, sour cream, or a spicy aioli! For even more cheesy flavor, sprinkle extra Parmesan cheese over the slices while they’re still hot so it melts slightly into the crispy layers.
Helpful Tips to Perfect This Recipe
- Cheese choice matters: Parmesan makes them ultra-crispy, while cheddar adds a melty, rich flavor. Try a mix of both for the best of both worlds!
- Get them extra crispy: After baking, turn off the oven and let them sit inside for 3-5 minutes with the door slightly open. This helps dry them out for extra crunch.
- Season smartly: Parmesan is naturally salty, so taste before adding extra salt to avoid over-seasoning.
- Store for later: If you have leftovers (doubtful!), store them in an airtight container at room temp for up to 2 days. Reheat in a low oven to bring back the crunch.
