In a paper bagPlace bananas in a brown paper bag and make a fold on top.Ethylene will build up and circulate within the bag, speeding up the ripening process.Check at certain intervals in order to take them out at your desired ripeness. This will make our bananas ripen pretty much overnight.
In the microwaveTake a fork or sharp knife and completely poke through the skin of the peel a couple of times on all sides.Place the banana in the microwave for 30 seconds.Let cool slightly and check if desired softness is met. If not, microwave for an additional 30 seconds.
In the ovenBananas cannot be overly green when using this method.Put unpeeled bananas on a baking sheet and place them in an oven set at 350ºF.Check on them frequently because time will vary. It will take about 15-20 minutes for this method. You know they’re ripe when the peels become shiny and black.

Expert Tips for Ripening Bananas
Tip 1: When ripening in a paper bag, place a ripe fruit such as an apple or tomato in the bag as well. These other fruits also emit ethylene and will enhance ripening.
Tip 2: Place bananas in warm areas such as near a heater, above your refrigerator, or in a sunny spot, as the warmth will help speed up the process as well.
Tip 3: If you want more ripened bananas, do not separate all the bananas at once. Only separate the one you want to eat and leave the others intact. This ripening process happens slowly but will ensure the sweetest and best bananas.
