Place an oven rack in the middle position and preheat to 400°F (200°C). 2. Prepare the Baking Sheet: Line a large baking sheet with parchment paper. Line a large baking sheet with parchment paper. Important: This is crucial to prevent the cheese from sticking and helps achieve a crispier result than a silicone mat. 3. Create the Cheese Base: Sprinkle the grated Parmesan cheese evenly over the parchment paper, creating a solid, thin layer from edge to edge.

A mandoline is best for this. It is very important to keep the onion slices intact; do not separate them into individual rings. Carefully lay the whole onion slices in a single layer over the bed of cheese. You can gently press and piece them together if they fall apart. Prepare your onion by slicing it as thinly as you can.

Season the Onions: Generously spray the tops of the onions with your cooking spray (like the flavorful duck fat spray). This helps them cook and brown. Sprinkle the Ranch seasoning powder evenly over the onions. Add a light sprinkle of black pepper. Taste your seasoning blend first. If it already contains a lot of salt, you may not need to add more, as Parmesan is also quite salty. If needed, add a very small pinch of salt.

Bake until Golden and Crispy Place the baking sheet in the preheated oven and bake for 20 to 25 minutes. Don’t be afraid to let it get deeply browned! The goal is a rich, golden-brown color across the cheese. This extended time is what makes the chips crispy rather than soft. The onions should be tender and cooked through.

Cool Completely: Remove the baking sheet from the oven and place it on a wire rack. Let it cool for at least 10-15 minutes.

Tips: For Maximum Crispiness: To achieve the best crunch, using parchment paper instead of a silicone mat is recommended, as it allows for better heat transfer to the bottom layer of cheese. Be sure to bake for the full 20-25 minutes, or until the cheese is a deep, uniform golden brown, not just lightly melted. Fixing a Soft Batch: If your chips aren’t as crisp as you’d like after cooling, you can place the pieces in a dry, non-stick skillet over medium heat. Cook for a few minutes to further brown and crisp up the bottom. Flavor Customization: Get creative with the flavors. For a “pizza” variation, try adding a layer of pepperoni on top of the onions before baking.
