Chop Bacon (4 ounce) into medium dice.
In a frying pan over medium-high heat, fry bacon until just starting to crisp and most of the fat has rendered. Scoop out bacon onto a paper towel lined plate, reserving 1/4 cup of bacon grease. Allow bacon to cool to room temperature before proceeding.
In a mini food processor combine half of the Panko Breadcrumbs (2/3 cup), bacon, Ground Black Pepper (1/4 teaspoon) and Smoked Paprika (1/4 teaspoon). Pulse until crumbly and bacon has broken down into bits. Add remaining bread crumbs and Salted Butter (1 tablespoon). Pulse until just combined. Set aside.
Cook Elbow Macaroni (1 pound) in salted water until al dente. Drain and rinse with cold water to stop the cooking process. Set aside.
Preheat oven to 350 degrees F (175 degrees C).
In a large sauce pan, heat the reserved bacon grease. Add All-Purpose Flour (6 tablespoon) and stir to combine. Cook over medium heat for 1 minute stirring often. Add Milk (1 cup), continue to whisk until smooth and the mixture starts to bubble.
Whisk in another cup of Milk (1 cup) and whisk until smooth.
Add remaining Milk (2 cup), whisk until smooth and allow to come to a boil. Reduce heat to medium-low and simmer for 10 minutes, stirring often.
Whisk in Dry Mustard (1 teaspoon), Kosher Salt (1 teaspoon), Worcestershire Sauce (1 teaspoon), Fresh Thyme (1 teaspoon), Ground White Pepper (1/8 teaspoon), Cayenne Pepper (1 pinch) and Ground Nutmeg (1 pinch).
Toss together White Cheddar Cheese (1/2 cup), Smoked Gouda (1/2 cup) and Parmesan Cheese (1/4 cup). Set Aside.
Add remaining Smoked Gouda (2 cup) and White Cheddar Cheese (2 cup) to the sauce, stirring until melted. Add cooked macaroni and stir to combine.
Divide equally into individual cocotte dishes or a 9x13-inch pan sprayed with nonstick spray. Top with the remaining cheese mix and then bread crumbs. Bake for 20-25 minutes until golden.
