Cook the bacon in a large nonstick skillet over medium heat until crisp, about 8 minutes. Remove and drain on a paper towel-lined plate. Wipe out the skillet.
Heat the butter in the skillet over medium heat. Add 2 bread slices. Top each with one-quarter of the cheese and 2 strips bacon. Spread 2 bread slices with some of the dressing and press them on top of the sandwiches, dressing-side down. Cook until the cheese melts and the bread is golden, 3 to 4 minutes per side. Repeat to make 2 more sandwiches, adding more butter as needed.
