Freeze green onions in water bottles - shake out the right amount and return to the freezer! Handy Tip - I always end up buying so many green onions and recipes never call for more than 3 stalks :P (Make sure the onions are dry before going in the freezer to prevent the freezer burn)
Good to know. How to grow your own green onions.... Next time you buy green onions, save the bulbs and toss them in a jar of water...you'll have a whole new bunch in 12 days! Changing out the water every other day is a great idea. Some have even found that they prefer planting their onions in a small pot of dirt or regrowing outside, especially helpful if you’re sensitive to onion smells.
