Bring water with salt to a rolling boil and cook pasta as per package instructions. Strain when done and keep aside.
Water, Salt, 3 Cups Macaroni Pasta
Preheat your oven to 320 Fahrenheit/ 160 Celsius.
Prepare the sauce in a pan. Melt the butter and drop in your all-purpose flour, keep on a lower heat setting. This is your Roux, but we don't make it too dark. Mix the butter and flour until you have a slightly bubbling golden paste.
Next, stir in the 3 cheese. Start with the cream cheese, then the shredded mozzarella and at last the grated parmesan. Make sure the cheese melts completely and then take the cheese sauce from the heat source.
⅔ Cup Cream Cheese, 2 Cups Shredded Mozzarella Cheese, ½ Cup Grated Parmesan Cheese
Assemble your mac and cheese. Place the cooked pasta in your casserole baking dish, coat, and toss in the cheese creamy sauce.
Top with shredded mozzarella cheese and parmesan.
1 Cup Shredded Mozzarella Cheese, ¼ Cup Grated Parmesan Cheese
Bake at 320 Fahrenheit/ 160 Celsius uncovered for about 25 minutes to golden brown and finish with the broiler oven setting, adding another 3 minutes or so until the top is crisp.
