This is the easiest batter for onion rings. Similar to my batter for fish, although this has a wee bit of spice added to it. I used purple onions only because I still have a partial bushel of these onions left and I’m trying to use them up.

Sweet onions or spanish onions are ideal for this recipe.

Deep frying and safe cooking tips

  • Never heat oil or shortening for deep frying in a pot on top of a burner.
  • Use only a thermostatically-controlled deep fat fryer which is properly designed for safe cooking with oil.
  • Follow the manufacturer’s instructions for care and cleaning. The Office of the Fire Marshal and your local fire department urge you to use ONLY thermostatically controlled deep fat fryers.

Course: Deep Fried


  • 2 Spanish onions
