• In a large skillet over medium heat, sauté bacon until brown and crisp this may take 6-7 minutes. Remove from pan and place on paper towel to drain and cool.
• Scoop out bacon fat; you may use it instead of butter if desired.
• Add the butter to cast iron or skillet and, as soon as butter melts, add garlic and onions. Saute until onion wilts - about 3 minutes.
• Whisk in the flour, continue whisking until it's thoroughly mixed with onions, and then cook for about a minute.
• Slowly add evaporated milk a little at a time, followed by milk and broth; you do not want the mixture to form any lumps. Simmer for 3-5 minutes until the mixture thickens slightly. 
• Add Creole seasoning and cayenne pepper.
• Bring to a simmer and continue simmering gently for about 2 minutes.
• Stir in the cheese mix and continue stirring until everything melts, evenly combines, and is smooth. Season with salt and pepper to taste.
• Then add the pasta and bacon, stirring to incorporate everything evenly. Transfer the pasta mixture into a pan or lightly greased 2-quart baking dish, then top with remaining cheese.
• Bake at 375F°/190℃ for 10-15 minutes or until golden and bubbly. Remove from the oven and top with remaining bacon and bread crumbs if desired. 

Bread Crumbs Toppings

• Place a small skillet on medium heat with a tablespoon or two of butter, then toss in a teaspoon minced garlic and stir for about 30 seconds.
• Throw in bread crumbs, saute for 3-4 minutes or until fragrant and slightly brown. Lightly season with salt and pepper if desired.
