1. Preheat broiler to high.
2. Cook bacon in a 10-inch cast-iron skillet over medium-high heat until crisp. Remove bacon with a slotted spoon, reserving drippings. Add onion and thyme sprigs to drippings in pan; sauté 3 minutes. Add garlic; sauté 1 minute. Stir in broth and remaining ingredients; reduce heat to medium and cook, uncovered, 10 minutes or until slightly thick, stirring occasionally. Discard thyme.
