There's something incredibly comforting about a creamy and cheesy Macaroni and Cheese made with 3 types of cheese, and when it's made effortlessly in your slow cooker, it's even better...
Macaroni and Cheese. What's not to love? It's truly the ultimate in comfort food.
This 3 Cheese Macaroni and Cheese is made with a blend of shredded Fontina, White Cheddar and Sharp Cheddar Cheeses, a creamy, extra cheesy sauce and an additional heavy sprinkling of Sharp Cheddar over the top. It's hard to eat just one bowl, trust me.
It begins with already cooked noodles and to the noodles I add melted butter, the three cheeses, eggs, sour cream, spices, milk and a homemade variation of Mornay Sauce. Mornay sauce is a simple white sauce which is typically made with Swiss cheese and/or Parmesan. For this macaroni and cheese recipe, I chose to substitute shredded sharp cheddar cheese to enhance the cheddar flavor.
The first step to making the sauce is to make the roux, which is simply combining melted butter with flour. After stirring and cooking for about 2 to 3 minutes, whisk in milk and continue whisking until the sauce thickens, which will happen quickly. Simmer for a few additional minutes, then stir in the shredded cheddar. Easy, right? The sauce can even be made a day ahead of time and kept in the refrigerator until you're ready for it.
A slow cooker can be your best friend in the kitchen. It's perfect if you're cooking for a family or if you're cooking for one. It's the easiest way to prepare dinner and takes no effort at all.
