Sprinkle pork chops with 1½ teaspoons salt and ½ teaspoon pepper. Let stand at room temperature for 15 minutes.
In a 12-inch cast-iron skillet, cook bacon over medium-high heat, stirring occasionally, until crisp, 10 to 12 minutes. Remove using a slotted spoon, and let drain on paper towels. Reserve 2 tablespoons drippings in skillet. Add pork chops; cook until browned, turning once, about 3 minutes per side. Remove from pan.
Add onion; cook, stirring occasionally, until tender, about 5 minutes. Add garlic and rosemary; cook until fragrant, about 1 minute. Add white wine; cook until reduced by half, about 1 minute. Stir in cream, mustard, remaining ½ teaspoon salt, and remaining ½ teaspoon pepper; bring to a simmer. Reduce heat to medium; cook, stirring occasionally, until slightly thickened, about 3 minutes. Whisk in cheese until smooth.
Add pork chops; continue cooking until a food thermometer inserted registers 150° and sauce is thickened, about 10 minutes more. Stir in bacon before serving. Garnish with rosemary, if desired.
