Preheat your oven to 400°F (200°C) to get it nice and hot for crisping those chips perfectly.

Slice your yellow onions into thin rings, about 1/8 inch thick, using a mandolin or sharp knife for the best results.

Spread the shredded Parmesan cheese evenly across a parchment-lined baking sheet, creating a cheesy base for your onion slices.

Arrange the onion slices in a single layer over the Parmesan, ensuring they don’t overlap for even cooking.

Brush the tops of the onions with olive oil, then sprinkle with sea salt, garlic powder, smoked paprika, and black pepper for a flavor boost.

Bake them in the preheated oven for 18-20 minutes, or until the cheese is golden brown and crispy, giving off a mouthwatering aroma.

Cool the chips for a few minutes before breaking them apart—this will enhance their crunchiness!
