Cook pasta for “al dente” on package instructions with salted water, drain. In a heavy bottomed pan, melt the butter over medium-high heat.
Add the flour and whisk until fully incorporated and you form a paste. Add the evaporated milk and continue whisking until the sauce starts bubbling.

Lower the heat to medium-low heat and slowly add the heavy whipping cream. In a bowl combine all the shredded cheese and divide the mixture in half. You will use half for the cheese sauce and half to layer on top when baking the Mac and cheese. Add a handful of the cheese to the sauce and whisk vigorously until fully incorporated. Do not add more cheese until the sauce is smooth and all the previous cheese you added has melted.

Place the oven rack in the center and pre heat your oven to 375F.
Once you have added all the cheese to the sauce, add the seasonings; salt, garlic, pepper, paprika and dijon mustard.
Add the cooked pasta to the cheese sauce and combine until all the noodles are coated in the sauce.

Use a 9x13 baking dish and add a layer of the pasta. Top with half the reserved cheese.
Add another layer of pasta and top with the other half of the reserved cheese.
Bake at 375F for about 20 minutes until all the cheese on top has melted and is slightly browned.
