While I’m lucky enough to live where it’s comfortable to grill outside most of the year, once the hot weather hits, grilling is a great way to help keep the house cooler. We love grilled onions and they are simple to prepare. One onion is typically enough for two adults.
Remove the papery skin and slice just enough off the root end for the onion to sit flat on a cutting board.
Carefully make two cuts, dividing the onion into quarters part way through the onion. Do not cut all the way through the bottom.
Place the onion in the middle of a square of heavy duty aluminum foil. Place a small pat of butter on top of the onion. Bring the four corners of the foil over the onion and give them a twist, sealing the onion inside. While grilling the main course, allow the onion to sit in a medium hot area of the grill, undisturbed for twenty to thirty minutes.
Remove from the heat and serve.
