This recipe comes together really quickly. Prepare the different bowls for the recipe and have everything ready to fry.

  • CUT ONION- Cut the onion in half (or leave it whole for onion rings); then slice really thin. Heat oil for frying. Cut the onion into thin strips or use a madoline slicer.
  • FLOUR- In the first bowl, add 1/2 cup flour. Dredging the onion rings in flour will allow the heavy whipping cream to stick to the onion and give the onion rings crispiness.
  • SOAK- Whisk together the heavy whipping cream with salt. Transfer the onion from the flour and soak in batches.
  • SEASONED FLOUR- Add remaining flour with salt, paprika, pepper and garlic powder. Dredge soaked onion strings into seasoned flour and layout onto a plate so the onion rings don’t stick together.
  • FRY ONION- Fry the onion strings in batches for best results. Serve the fried onion with the homemade dipping sauce. NOTE: Work in batches so the onion straws don’t stick together.
PRO TIP: Be sure oil is sizzling hot (very important!). If you add the onion strings into cold oil, the batter it was dredged and soaked in will come right off and the onion rings will be really unpleasant.
