Instead of using diced or minced onion as a seasoning to complement savory dishes, some onions are tasty enough to become the stars of the show. Vidalia onions — named for the city in Georgia where they originated — have a sweet, savory combination that makes them an ideal baking onion. Microwave whole onions to prepare a simple, yet memorable, side dish.

Things You'll Need

Remove the outer peel of the onion and place it onto the cutting board. Slice off the top and bottom edges of the onion with the chef’s knife.

Insert the tip of the knife into the center of the onion and cut out the center core — about the center 1 inch to 2 inches of a large onion. Place about 1 tbsp. of butter inside the cavity of the onion.

Place the onion into the baking dish. Microwave it uncovered for about five minutes on high power.

Season the onion with salt and pepper after you finish cooking it.


  • For another preparation option, cut an “X” in the top of the onion, leaving the core intact. Tuck small amounts of butter inside each slice of the “X.” The “Chicago Tribune” recommends covering the baking dish with plastic wrap during the cooking process to retain moisture.
