Three Cheese Bacon Mac and Cheese

Preheat oven to 400 degrees F.
Place two cooling racks on top of a jelly pan and lay the bacon out on it, the bacon can be touching to start, it will shrink up during cooking, and bake bacon for 15 - 18 minutes. Once bacon finishes cooking, transport it to a paper towel-lined plate to rest.
Turn oven down to 350 degrees F.
Bring water to a boil in a large pan, making sure to salt it. Once boiling, add in pasta and cook until Al dente.
While pasta and bacon are cooking, add butter and heavy cream to a medium saucepan. Once butter has melted, whisk in flour and seasonings and allow to simmer for a couple of minutes.
Whisk in 1/2 cup of Parmesan cheese and the other cheeses one at a time until completely melted, continue to simmer for a couple minutes, stirring occasionally. Add additional salt and pepper to taste.
Once pasta had finished cooking and has been drained, put it back in the pan and then pour cheese sauce over it.
Chop up bacon and transfer to the pan and stir it in and transfer mac n cheese to a medium-sized casserole dish.
Add breadcrumbs and 2 tablespoons of butter to a medium skillet and toast until breadcrumbs are golden brown. Remove from heat and add the Parmesan cheese. Sprinkle the breadcrumbs over the top of the mac and cheese.
Bake for 20 minutes and enjoy warm.
