The cheese melds into a golden shell hugging sweet onion slivers with just the right punch of spice. If you have ever wished for onion rings you could snack by the handful this is your recipe.

Ingredients
- Yellow onions: This recipe is day and night better with yellow onions for their balance of mellow bite and sweetness. Look for hefty firm onions for the best slices
- Parmesan cheese: Freshly grated is key for melt and flavor though pre-shredded works in a pinch. Seek nicely aged Parmigiano Reggiano for true flavor pop
- Avocado oil: Gives clean crispness to each chip but you can use olive oil in a pinch. Go for a light neutral oil with a high smoke point
- Spice blend: Paprika coarse sea salt garlic powder seasoning salt and ground black pepper round out the flavor. You can play with dried herbs or swap in smoked paprika for extra depth. Use the freshest spices you have for punch
- Parchment paper: The secret for even melting and easy cleanup. Invest in good parchment that does not curl
Instructions
- Preheat and prepare:
- Set your oven to 400 degrees Fahrenheit and line a sturdy rimmed baking sheet with parchment paper. Make sure the parchment fits flat so your chips bake evenly
- Grate and layer cheese:
- Take your block of parmesan and use a coarse grater to create generous shreds. Spread these in a single thin layer over the parchment. Think of it as the cheesy bed for your onions. Do not clump so every chip crisps up
- Slice and arrange onions:
- Use a sharp knife or mandoline for waferthin onion slices. Aim for about one eighth inch thick. Lay these gently across the cheese. Try not to overlap for max crunch and even baking
- Brush with oil:
- Dip a pastry brush in avocado oil and lightly coat the onion slices. This little bit of oil brings crispiness without heaviness
- Season generously:
- Sprinkle paprika sea salt garlic powder seasoning salt and black pepper over the onions. Pay special attention to the edges for big flavor in every bite
- Bake to perfection:
- Slide the tray on the center rack. Bake for 14 to 18 minutes or until the cheese has bubbled to a deep golden brown and the onion edges are caramelized. Watch closely at the end so you do not cross from golden to burnt
- Cool and break up:
- Let the tray cool completely on the pan. The chips will finish crisping as they cool. Gently break them into chip sized pieces and lift from the parchment

Perfect make ahead appetizer. The way the parmesan and onion fuse is pure magic for me I always look forward to the crispy golden bits along the edge. My family loves piling these up with a tangy sour cream dip for game day memories
Storage Tips
Keep leftover chips in an airtight container at room temperature for up to two days. If you want to restore their crispness pop them on a baking sheet for a couple minutes at 350 degrees. If making ahead for a party cool the chips completely before storing to avoid sogginess. Parmesan cheese helps to keep these crisp longer than chips made with softer cheese
Ingredient Substitutions
Vidalia onion slices work beautifully and bring extra sweetness. If you are dairy free try a good quality vegan parmesan but watch for different melting times. Olive oil is a solid swap for avocado oil just use one with a mild flavor so it does not overpower the onions
Serving Suggestions
Serve alongside burgers sliders or even tucked into wraps for crunch. These chips are excellent on a charcuterie board either whole or crumbled over warm dips. A bright herby yogurt or sour cream dip makes the perfect match for the cheese and onion combo
Cultural Context
Onion rings have deep roots in American diner culture but this viral version has taken social media by storm for the way it reinvents the classic into something lighter and crisply snackable. Cheese and onions have also been paired together for ages across Mediterranean and European cuisines
Seasonal Adaptations
Try using spring onions for a milder chip in early summer. Add fresh chives or thyme in place of paprika for a springy vibe. Swap in smoked paprika or chipotle powder for a wintery smoky snack

A cold pan start gives the best edge crisp when baking. Let the onions cool fully or they will not stay crispy
