Preheat Grill: Heat grill to medium-high heat

Grilling onions for burgers can be a tricky task, but with the right preparation and technique, you can easily achieve the perfect char and caramelization. To begin, preheat your grill to a medium-high heat. This will help the onions retain their shape and structure while cooking, while allowing them to get a nice sear on the outside.

Before grilling, cut your onions into thick slices. You can also quarter them, depending on the size of your burgers. Make sure to get rid of any excess moisture by blotting the onions with a paper towel. This will help them cook evenly and prevent any flare-ups on the grill.

Next, season the onions with oil, salt, and pepper. You can also opt for more flavorful seasonings, such as garlic powder or chili powder, if you so desire. Then, place the onions directly on the grill. If you’re using a gas grill, make sure to leave the lid open to prevent the onions from steaming.
