Let’s Prepare Some Macaroni and Cheese!

This oven baked mac and cheese is so easy to make with just a few ingredients from your pantry and fridge…just combine and bake!

  1. Cook the macaroni and then drain and cool.
  2. In a large stockpot, melt the butter. Add enough of the flour to create a roux. Stir over medium heat for about a minute until it is thickened and caramel colored.
  3. Whisk a cup of milk at a time into the roux, making sure there are no lumps. Keep adding milk and turn up to high.
  4. When sauce is thick and bubbly, remove from heat and stir in 3 cups of the shredded cheese.
  5. When the cheese is melted, add the sour cream and stir well. Season with salt and pepper.

How to Bake It

The key to baking this oven mac and cheese is to keep the casserole dish in the middle of the oven and remove once the cheese on the top is bubbly and just a little browned.

  • Stir in the cooked macaroni and pour the mixture into the greased casserole dish.  Sprinkle on the remaining cheese.
  • Bake until the cheese on top is fully melted and slightly browned.

Once baked you can serve nearly anything with this mac and cheese, or simply top with crispy crumbled bacon. Try adding a cold, crisp spinach strawberry salad, some roasted cauliflower, or even some crispy carrot fries!

Reheat it Perfectly!

Keep the mac and cheese in a sealed container in the fridge until it’s ready to be reheated. Simply stir the mac and cheese, add a little milk, and reheat in the microwave or in a pot on the stove. Adjust the salt and pepper and serve!
