  • 1 lb frozen onion rings
  • 1/4 Cup vegetable oil
  • 2 tsp season all salt
  • salt and pepper to taste


  • Preheat the oven to 400 degrees
  • Cover a baking sheet with aluminum foil (This is optional but it does make clean up quick and easy ).
  • Spread the rings out across the baking sheet.
  • Pour oil and season all salt onto the rings and baking sheet. 
  • Using your hands, mix the oil, seasoning and rings well.
  • Spread the onion rings out as much as possible so that the hot oven air canc circulate around them.
  • Bake at 400 degrees for about 20 minutes (refer to the package for your particular brand of onion rings). 
  • Remove from the oven, allow to cool slightly, taste and sprinkle with more salt and pepper if needed. 



  • Make certain to refer to your own package of frozen onion rings for time and temperature settings, this will differ with brands. 
  • If you like your onion rings more crispy, allow to cook a little longer, if you prefer less crispy, take them out sooner. 
  • It is important to mix the rings with the oil by hand as this helps coat everything evenly.  Be ready to wash your hands immediately afterward. 
  • PRO TIP:  For slightly different flavor, exchange the season all salt for garlic powder, onion powder or parmesan cheese!
