Ingredients

  • 3 large sweet onions
  • 2 cups shredded cheddar cheese
  • 2 tsp ranch seasoning or seasoning of choice
  • Ranch or marinara sauce for dipping

Instructions

  • Preheat oven to 375°F. Line two baking sheets with parchment paper and grease lightly.
  • Slice the onions into very thin rounds, about 1/4-inch thick (you'll need 16 slices total).
  • Arrange 8 small piles of shredded cheddar cheese on each baking sheet, spacing a few inches apart.
  • Place one onion round on top of each pile of cheese. Sprinkle evenly with ranch seasoning.
  • Bake for 11-13 minutes, watching closely towards the end so they don't burn. They're ready when crispy and lightly browned.
  • Let cool for 5-7 minutes before removing crisps from baking sheets.
  • Serve warm with ranch or marinara sauce for dipping.

Notes

  • Use a very sharp knife or mandoline to slice onions evenly and thinly for optimal crispiness.
  • Watch closely while baking - crisps can go from golden to burnt quickly.
  • Let cool for 5 mins before removing from sheets to allow crisps to fully firm up.
  • Change up the seasoning with cajun, taco seasoning, Italian, or other desired blends.
  • Crisps will stay fresh for up to 5 days stored at room temp in an airtight container.
  • Reheat at 400°F for 2-3 minutes until hot and crispy.
