Crockpot Mac and Cheese Bar

I have been in charge of my workplace employee gathering events for the past eight years. I love planning these, because they almost always revolve around food. I am about to hand off the baton to someone else, who will coordinate the events for the company.  In order to do this, I am organizing a potluck for people who volunteered to help this year.

My contribution to the potluck is going to be this very decadent crockpot macaroni and cheese. I was sceptical that a cheese sauce in the crockpot would be creamy, and smooth, but you won't believe how good this is.

 There is a little "cheese science" in my combination of ingredients here. Normally,  I am opposed to the "processed cheese spread" needed here. But, the oil content is needed to keep this smooth in the crockpot. Don't worry, you won't really taste it. This is amazing...and the topping choices are endless. Feel free to post suggestions !

Crockpot Mac and Cheese Bar
3 cups uncooked macaroni
3/4 cup butter, melted
1 3/4 cup milk
3 eggs
1 can evaporated milk
1 pound processed cheese spread, cut into cubes
2 cups pepper jack cheese, shredded
2 cup shredded sharp cheddar cheese
Salt and pepper to taste
Toppings, such as bacon, salsa, chili, green onions, pickles
Cook macaroni according to package directions,  leaving slightly undercooked.  In a large bowl, mix together butter, eggs, and milks. Pour mixture into the crockpot,  then gently stir in macaroni and cheeses.  Cook on low for 2 to 3 hours, stirring at least once. Serve with your favorite toppings.
