Equipment

1 Air fryer
1 Baking Dish
1 Chef's Knife
1 Cutting Board

Ingredients

4 Onions We like the Vidalia variety for its sweetness
1/4 Cup Butter
4 Tbs Butter
Salt
1/4 Cup Parmesan Cheese Grated

Instructions

Gather your ingredients
Pre heat your air fryer to 350 F
Slice the onion at the top, making sure to leave the root intact
Leave the skin on the onion
Using your paring knife insert it into the middle of the onion on the side where you sliced it. You want to make a diviet to hold the butter, vinegar and rosemary.
Add a tablespoon of butter to each onion
Add a sprig of rosemary to each onion
Salt the onions generously
Drizzle the Balsamic into each divit
Once you smell the onions really cooking you can remove them and sprinkle the parmesan over them usually at about the 6 -10 minute mark
Return them to the airfryer for 5 more minutes or until the centers are soft and the tops are brown

Notes

Depending on the size of your onions the cook time may vary

Small onions can be ready in 20-25 minutes

Larger onions can take anywhere from 30 minutes to 55 minutes

Vidalia Onions are prefered for their sweetness
