Start by preheating your oven to 350 degrees and lightly greasing a 9×13-inch casserole dish.
Cook the pasta as the package directs.
In a skillet, cook chopped bacon over medium heat until crispy.
Dice the jalapenos and remove the seeds.
In a large skillet, combine cream cheese, broth, and milk. Cook on medium-low, stirring frequently, until the cream cheese melts.
Add the shredded cheese and the garlic, continuing to cook until the cheese melts.
Mix in the pasta, chicken, and half of the diced jalapenos if there’s enough space in your skillet (or use a large bowl).
Pour the mixture into the prepared casserole dish and bake for 15 minutes.
Remove the baked casserole, top it with the remaining cheese, jalapenos, and crispy bacon, and bake for another 5 minutes.
