Preheat your oven to 400°F (200°C) and line a large rimmed baking pan with parchment paper.

Spread an even layer of 8 ounces of freshly grated parmesan cheese over the parchment paper.

Slice 3 yellow onions very thinly, aiming for about ⅙ inch in width, and lay them evenly over the parmesan cheese.

Drizzle 2 tablespoons of avocado oil over the onions, then brush or massage the oil to coat them evenly.

Sprinkle 2 teaspoons of paprika, 1 teaspoon of coarse sea salt, 1 teaspoon of garlic powder, ½ teaspoon of seasoning salt, and ¼ teaspoon of ground black pepper evenly over the onions.

Place the baking pan in the preheated oven and bake for 25-30 minutes, watching until golden brown and crispy.

Once finished, remove the pan and let the chips cool for 10 minutes before breaking them apart and serving.
