how to make this broccoli chicken pasta casserole

recipe notes and tips

  • Use a preheated oven.
  • To make life even easier, use rotisserie or leftover chicken.
  • Buy fresh broccoli and cut it into florets. It’s fresher this way and you have control over how big you want your florets.
  • Stir your pasta as soon as you drop it in the water, this prevents the pasta from sticking.
  • Cook your pasta a minute short of al dente, this will make sure your pasta isn’t too mushy after baking.
  • You can use any fat content milk you’d like to make this dish rich and creamy, or lighter.
  • Ideally, shred your own cheddar, pre-shredded cheddar never melts that well.
  • Also, consider adding a sprinkle of red pepper flakes, for a touch of heat, if you like.
  • Add a dash of nutmeg for a touch of warming winter flavor.

Ingredients

  • 8 ounces uncooked whole-wheat pasta
  • 1 large head of broccoli about 1 pound of florets
  • 2 tbsp. olive oil
  • 1 small white onion
  • 8 ounces cremini mushrooms
  • 4 cloves garlic minced
  • 2 tbsp. cornstarch
  • 1-1/2 cups milk of choice
  • 1 cup chicken or vegetable stock
  • 1 tbsp. Dijon mustard
  • 1 tsp. kosher salt
  • 1/4 tsp. freshly-cracked black pepper
  • 2 cups diced cooked chicken breast dice or shredded, I used rotisserie chicken
  • 1 1/2 cups shredded cheddar cheese divided

Instructions

  • Heat the oven to 400°F and cook pasta according to the package directions. Stir occasionally, until pasta is al dente, about 10-12 minutes.
  • Cut the broccoli into bite-size pieces. Quarter the mushrooms and dice the onion. Add broccoli florets to the pasta, about a minute or two before the pasta is done.
  • When finished cooking, drain well in a colander and run under cold water to stop the cooking process.
  • Next, heat olive oil in a pan over medium-high heat. Add onion and sauté for 3 minutes, stirring occasionally. Add mushrooms and garlic, cook, until mushrooms are slightly golden brown.
  • Meanwhile, whisk cornstarch and 1/4 cup milk to a bowl and set aside.
  • Reduce the heat to a low and pour the stock and remaining 1 1/4 cup of milk into the pan. Add mustard, salt, and pepper, mix well to combine. Cook until the mixture starts to simmer.
  • Pour in the prepared cornstarch and milk mixture, mixing thoroughly until sauce is thickened.
  • Take off the heat and stir in 1 cup of the shredded cheese. Taste and adjust the salt and pepper according to your taste.
  • In a baking dish, add the cooked pasta, broccoli, and diced chicken. Pour over the mushroom sauce, and stir to nicely coat all the ingredients.
  • Smooth the top with the back of a spoon and sprinkle with the remaining 1/2 cup of shredded cheese. Bake in preheated oven for 15 minutes, until cheese on top, is bubbly and golden.
  • Serve warm and enjoy!
