First, cut the bacon into small pieces—kitchen shears make this easy. Fry in the skillet over medium-high heat until it’s crisp and golden. Then transfer bacon to a paper towel-lined plate to drain, reserving about a tablespoon of the fat in the pan (you’ll use that flavor). Meanwhile, bring a large, salted pot of water to a boil for the tortellini, and once the bacon is done, add tortellini and cook per package instructions.
With the skillet still hot (with that bacon fat), add minced garlic and cook just until fragrant (about 30 seconds to a minute). Pour in chicken broth, heavy cream, and softened cream cheese. Stir over medium heat until the sauce is smooth and starting to reduce—this takes about five minutes. The cream cheese adds both tang and thickness without needing thickening agents.
Once the sauce is smooth, stir in the crispy bacon and freshly grated Parmesan. Drain the tortellini, reserving a splash of pasta water just in case you need to thin the sauce. Toss the pasta into the sauce, gently coating every piece. Season with salt and pepper to taste. When it looks glossy and luscious, remove from heat and dig in.
