Boil a large, salted pot of water and cook the tortellini.
Cook up and cut the bacon into small pieces.
Take the pan off the heat and remove the bacon to a paper towel lined plate. Drain most of the bacon fat from the pan (keep about 1 tablespoon in there).
Stir in the garlic, chicken broth, cream, white pepper, mustard powder, and cream cheese. Return the pan to the burner (medium heat), and stir until you’ve got a smooth sauce and it’s reduced to your liking (about 5 minutes).
Stir in the parmesan cheese and bacon. Take the pan off the heat and toss with the drained tortellini (but if the sauce is too thick, thin it with a few spoonfuls of the hot pasta water prior to draining it). Season with salt and pepper as needed.
