Easy Chicken Mac and Cheese

For the chicken, you can use leftover chicken, a rotisserie chicken from the deli, or quickly poach a few chicken breasts.

Oven-baking instructions: If you’d prefer a casserole-style mac and cheese, you can transfer the contents to an 8x8 baking dish, top it with breadcrumbs, and bake it at 350°F for 20 minutes. This is a great option if you want to make the dish in advance.


  • Prep time: 20 minutes
  • Cook time: 45 minutes
  • Yield: 4 to 6 servings


For the Chicken Mac and Cheese

  • 8 ounces dry macaroni
  • 1/2 sweet onion, chopped
  • 1 clove garlic, minced
  • 1/4 cup unsalted butter
  • 3 tablespoons all-purpose flour
  • 2 cups whole or 2% milk
  • 2 cups grated cheddar cheese
  • 1 teaspoon dried mustard (optional)
  • 2 cups shredded cooked chicken (See Recipe Note)
  • 1/4 teaspoon salt
  • 1/4 teaspoon black pepper

For the Crispy Breadcrumbs:

  • 2 tablespoons unsalted butter
  • 3/4 cup breadcrumbs, such as panko


1 Cook the pasta: Bring a pot of salted water to a boil and cook the pasta until al dente, or according to package instructions. Drain and rinse with cold water to stop the cooking and keep the pasta from sticking together. Set aside.

 2 Cook the onions and garlic: In a large pot over medium heat, add butter. Once the butter is melted, add chopped onions and cook for a few minutes until they turn translucent. Then add garlic and cook for another 30 seconds. Stir the flour into the onion and garlic mixture and cook for a minute.

3 Stir in the milk, mustard and cheese: Slowly add the milk while stirring. The flour and onion mixture will thicken as you add the milk.

Once all the milk is added, stir in the grated cheese and mustard. Continue to cook, stirring occasionally, until the cheese has melted.

4 Stir the chicken and pasta into the sauce: Once the cheese is melted, stir in the chicken and cooked pasta. Taste and season with salt and pepper as needed.

5 Cook the breadcrumbs: Whenever you have a few spare moments while assembling this pasta (like, while cooking the onions or while waiting for the cheese to melt), cook the breadcrumbs.

Melt the butter in a small skillet over low heat. Stir in the breadcrumbs until well combined. Continue to stir over low heat until the breadcrumbs are browned, 3 to 4 minutes. Remove from the heat and let cool. Breadcrumbs can also be toasted ahead of time and stored in an airtight container.

6 Serve: Ladle the cheesy chicken macaroni right out of the pot when it’s super creamy, and top it with crispy breadcrumbs.

    I made this tonight, but skipped the onions because I didn’t have any on hand. I think next time I would skip the breadcrumbs as well, I didn’t see a lot of added value really…


  • Christine

    8 ounces of dry macaroni by weight or is that a one cup measure?

  • Karen

    Followed recipe exactly using oven method… everybody loved it! Served with a salad.

    I add broccoli to my Chicken Mac and Cheese. Mac and Cheese is a base for any addition to dress it up, like ham bits, pimiento, green onion, beans, chili to name a few. Love it.

    Also great with Tuna subbing for the Chicken.

  • Dr Martin Huang

    Nice! For me, I would just replace the chicken with Honey Baked Ham in cube size. So that when it’s eaten, there will be a chewy yet succulent texture.

    Can this be made in a crock pot for potlucks? or if not made in it at least kept warm?

    • Emma Christensen

      Hi, Carol! Emma here, managing editor for Simply Recipes. I’m not sure about making it in the crockpot, but you could definitely keep it warm in one. Have a little milk handy so you can stir it in if the mac and cheese thickens up too much. Let us know how it works out!
