In our quick and easy low-carb onion rings chips recipe, the onions become sweet and caramelized and the Parmesan adds a salty, crispy crust.
Preheat the oven to 400 F.
Peel and slice the onions thinly.
Cover a baking sheet with parchment paper.
Sprinkle the grated Parmesan over the baking sheet.
Place the sliced onions on top of the Parmesan.
Brush the olive oil over the top of the onions.
Sprinkle the garlic power over the onions and season well with black pepper.
Place in the oven and cook for 15 to 20 minutes until the cheese is golden.
Let the cheese cool and harden for 10 minutes.
Break or slice apart and then serve.
