While the meat rests, prepare the aioli: In a medium bowl, stir together all of the ingredients. Adjust the seasoning with salt and pepper.

Heat the grill to medium-high. Cook the burgers until interior reaches 175°F, about 5 minutes per side.

Put a slice of cheese on each pattie during the last minute of cooking time.

Transfer the patties to a clean plate and tent loosely with foil.
