Preheat oven to broil. Cook macaroni according to package directions. Drain.
Meanwhile, fry bacon until crisp, about 5 minutes, then drain on paper towels, reserving 1 tbsp. grease. Set bacon aside.
In the warm pasta pot, mix reserved grease, 2 tbsp. butter, the herbs, onions, garlic, and soft cheeses. Mix in warm pasta and bacon. Spoon into 4 ramekins (1 1/2-cup size); sprinkle with cheddar cheese.
In a small bowl, combine remaining 1 tbsp. butter and the bread crumbs, stirring to combine. Sprinkle evenly over cheese.
Broil ramekins until golden and bubbling, about 3 minutes.
