  • 1 pound Chicken Breast boneless, skinless
  • 2 cups Chicken Broth
  • Pinch Salt
  • 8 ounces Elbow Macaroni
  • 1-2 tablespoons Salt for the pasta water
  • 10-12 ounce Package Steam-in-the-Bag Broccoli Florets
  • 2 tablespoons Butter
  • cup Plain Breadcrumbs
  • 2 10 ounce cans Condensed Cream of Chicken Soup
  • 4 ounces Prepared Cheese like Velveeta
  • 1 cup Shredded Cheddar Cheese


  • You will also need: casserole dish (3 quart), aluminum foil, mesh strainer, instant read thermometer

Poach the chicken breast

  • Place the chicken in a saucepan that’s large enough that the pieces fit side by side without overlapping. Cover the chicken with the chicken broth. Add a pinch of salt.
  • Start the chicken on high heat. When the liquid starts to boil, lower the heat to medium-low and cover. Simmer gently for 15-20 minutes or until the chicken is at least 165°F at its thickest part.
  • Remove the chicken breast from poaching liquid and set it on a cutting board to cool. Don’t discard the cooking liquid. Strain it using a mesh strainer.
  • Cut the chicken into bite-sized cubes when it’s cool enough to handle.

Pasta instructions

  • Bring a large pot of water to a boil over high heat. When the water is at a full boil, add 1-2 tablespoons of salt and the macaroni.
  • Cook the pasta to package directions for al dente. Avoid overcooking the pasta. Drain and reserve.

Par-cook the broccoli

  • Cook the broccoli for 1-2 minutes in the microwave. Carefully open the bag and let the steam escape so that the broccoli doesn’t continue cooking. Cut any large florets into smaller pieces when it’s cool enough to handle.

Make the breadcrumb topping

  • Melt the butter in a non-stick skillet over medium heat. When the butter is melted, add the breadcrumbs. Stir until completely moistened. Remove the skillet from the heat and reserve.

Make the sauce

  • Heat the cream of chicken soup, reserved chicken broth and the 4 ounces prepared cheese in a large saucepan over medium heat. Stir the sauce with a whisk or fork until the cheese is melted and the sauce is smooth. Remove the pan from the heat and stir occasionally.
  • Preheat oven to 375°F

Build and bake the casserole

  • Add the macaroni, diced chicken and broccoli to a large, oven-safe casserole dish or baking pan. Stir to combine the ingredients.
  • Add the creamy sauce.
  • Stir gently to combine the ingredients well. Keep stirring and tossing until everything is coated with sauce.
  • Sprinkle the top with the shredded cheese and breadcrumbs. Sprinkle them lightly, don’t pack them down.
  • Place the casserole dish on a baking sheet, just in case it bubbles over. Cover the top loosely with a piece of aluminum foil and bake for 30 minutes.
  • Uncover and cook another 10-15 minutes until the breadcrumbs are golden and the chicken and broccoli casserole is bubbly.
  • Let the casserole rest for a few minutes before serving.


Order of preparation:
Start the water for the pasta and set the chicken to poach.
Prepare the breadcrumb topping and broccoli while the chicken and pasta cook.
Prepare the sauce. Leave the sauce for last because we need the chicken broth from the poached chicken to make it.
