Notes

  • Use sweet onions 
  • The size of the onions won't matter. I like to use medium onions If you love onions, you can use large onions. 
  • Use any of your favorite seasonings you have on hand. You can get creative and use whatever seasonings you prefer.
  • I liked adding a bit of cheese to my onion boil, it reminds me of French onion soup. The cheese is optional.
  • You can serve onion boil as a side dish with protein.
