I have tried every baked macaroni and cheese recipe out there and they all turn out too dry. This is the cheesiest,creamiest, recipe I've ever made. Delicious!! I used three cheese Alfredo style pasta sauce, but you can use whatever you like.
Lightly mist an 11x7 inch(2 quart) glass or ceramic baking dish with vegetable oil cooking spray and set aside.
Bring a large pot of water to a boil over high heat.Add salt,if using,and stir in the macaroni.Reduce heat to medium-high and cook uncovered about 8 minutes.Reserve 1 cup of the pasta cooking water,then drain the macaroni well in a colander.
Transfer the macaroni to the prepared baking dish.Add the pasta sauce,2 cups of the cheese,and the reserved pasta cooking water,and stir until ingredients are well combined.Scatter the remaining 1 cup of cheese over the top.
In a small bowl,toss the olive oil with the bread crumbs, and then scatter on top of the cheese.
Bake until the macaroni and cheese is bubbly and the crumbs are lightly brown,25 to 30 minutes.
