Ingredients Equipment Method Notes

Ingredients
  

  • 2 large onions, thinly sliced
  • 1 cup shredded cheddar cheese
  • 1/2 cup breadcrumbs
  • 2 tbsp grated Parmesan cheese
  • 2 tbsp olive oil
  • 1 tsp garlic powder
  • 1 tsp dried oregano
  • salt and black pepper, to taste
  • 1 cup ranch dressing
  • 1 tbsp hot sauce
  • 1/4 tsp cayenne pepper (optional)
  • 1 tsp fresh lemon juice (optional)
  • pinch of black pepper

Equipment

  • baking sheet
  • parchment paper
  • mixing bowls
  • knife
  • cutting board

Method
 

  1. Preheat oven to 400°F. Line a large baking sheet with parchment paper and set aside.
  2. Place the thinly sliced onions in a large bowl and toss with olive oil until evenly coated.
  3. In a separate bowl, mix together the breadcrumbs, shredded cheddar, grated Parmesan, garlic powder, dried oregano, salt, and black pepper until evenly combined.
  4. Add the oiled onion slices to the cheese and breadcrumb mixture. Toss gently, pressing lightly so the coating adheres well to each slice.
  5. Spread the coated onion slices in a single even layer on the prepared baking sheet, making sure no slices overlap.
  6. Bake for 15–20 minutes, flipping carefully halfway through, until golden brown and crisp around the edges.
  7. While the crisps bake, combine ranch dressing, hot sauce, cayenne pepper if using, lemon juice, and a pinch of black pepper in a small bowl. Stir until smooth. Refrigerate until ready to serve.
  8. Remove the crisps from the oven and serve warm alongside the chilled spicy ranch dipping sauce.

Notes

Slice onions thinly and evenly for the best crisp texture. Do not overcrowd the baking sheet—spread in a single layer to ensure proper crisping. Use freshly shredded cheese for better melting and flavor. Reheat in the oven or air fryer to restore crispiness.
