Why You’ll Love This Cheesy Onion Crisps Recipe:

  • Just 4 simple ingredients required
  • Crazy quick prep and cook time (less than 25 minutes!)
  • Perfectly crispy, melty, and so satisfyingly flavorful
  • Versatile base that can be seasoned any way you like
  • Baked instead of fried for a lighter, healthier snack

Key Ingredients You’ll Need:

  • Sweet onions – yellow, white or red all work. The natural sugars help them caramelize nicely.
  • Cheddar cheese – the sharper the better for max flavor! Other cheeses like pepper jack also taste amazing.
  • Ranch seasoning – for that addictive ranch flavor we all crave. Try Cajun, Italian, or taco seasoning for other fun variations.
  • Marinara sauce or ranch for dipping – these crisps need a creamy, tangy dip to make them even more irresistible!

How to Make Cheesy Onion Crisps:

  1. Preheat oven to 375°F. Line two baking sheets with parchment paper and grease them lightly. This helps the cheesy crisps slide right off later.
  2. Slice onions into very thin rounds, about 1/4-inch thick. You’ll need 16 slices total.
  3. Portion out 16 small piles of shredded cheese onto the prepared baking sheets, spacing them a few inches apart.
  4. Place an onion round on top of each mound of cheese and sprinkle with ranch seasoning (or desired seasoning blend).
  5. Bake for 11-13 minutes, keeping a close eye on them in the last few minutes so they don’t burn. They’re ready when crispy and lightly browned.
  6. Let them cool for 5 minutes before trying to remove them from the sheets. They’ll crisp up more as they cool.
  7. Serve warm with marinara, ranch or any dipping sauce you like for dunking!

Pro Tips for Best Results:

  • Use a super sharp knife or mandoline to slice the onions very thin and evenly. This helps them get lacy and crisp.
  • Grate cheese from a block instead of using pre-shredded for ultimate melting.
  • Keep an eye on them towards the end of baking – they can go from perfect to burnt quickly!
  • Let the baked crisps cool for a few minutes before removing so they have time to firm up.
  • Double the batch because these will go fast! They’re easy to make more.
  • Switch up the seasonings with cajun seasoning, Italian, taco, or other blends you like.
