In a large pan with tall sides, cook the bacon over medium heat.
When bacon is halfway cooked, add the chopped jalapenos. Continue cooking until the bacon is browned and crispy.
Remove bacon and jalapenos with a slotted spoon and place on a paper towel-lined plate. Remove all but 1 tablespoon of bacon grease from the pan.
Lower the heat to medium-low. Add the pasta and chicken broth to the pan.
Cook the pasta in the broth for 10-12 minutes, stirring often to prevent sticking, until the pasta is al dente.
Add the evaporated milk and seasoning. Stir well and allow the milk to warm through.
Stir in the pepper jack cheese, followed by ¾ of the bacon and jalapeno mixture.
Mix thoroughly, cover with a lid, and remove from heat. Let sit for 5 minutes to allow the sauce to absorb and become creamy.
If the pasta isn't creamy enough, stir in more cheese.
Top with the remaining bacon and jalapenos. Serve as a delicious main dish or appetizer.
Optional: For a heartier main dish, cook and chop chicken breasts beforehand and mix them in before serving.
