25 - 30Ritz Crackerscrushed into crumbs (approximately 1 sleeve)
Preheat oven to 400 degrees. Lightly grease a 9 x 13 baking dish with cooking spray. Set aside.
Bring a large pot of salted water to a boil. Cook the elbow pasta for approximately 8 minutes, until al dente. Drain the pasta and set aside (we're going to reuse the pot, so no need to wash).
Ok back to the pot we used for the pasta. We're going to make a roux (a mixture of flour and fat, in this case butter) as the base for our sauce. Melt the butter in the pot over medium low heat. Once melted, add in the flour, stirring constantly until the roux is golden and bubbling. Gradually add in the warm milk and continue to stir, cooking it down until smooth and thickened. This will start to look like pancake batter when ready. Turn off the heat.
Add in all the cheese and stir until smooth and all the cheese is melted. Add your cooked noodles into the cheese sauce and stir until coated. Pour the cheesy noodles into the prepared baking dish and top with the cracker crumbles. Bake uncovered for 20 minutes and enjoy your cheesy masterpiece!
