Equipment

  • large stockpot
  • large sauté pan
  • 9 x 13-inch baking dish

Ingredients
  

Pasta and Broccoli

  • 8 ounces uncooked pasta whole-wheat rotini
  • 1 large head broccoli cut into bite-sized florets (about 1 pound)

Sauce Ingredients

  • 2 tablespoons butter or olive oil
  • 1 small white onion thinly sliced
  • 8 ounces baby bella mushrooms thinly sliced
  • 4 cloves garlic minced
  • 3 tablespoons flour
  • 1 cup chicken or vegetable stock
  • 1.5 cups milk
  • 1 teaspoon Dijon mustard
  • 0.5 teaspoon fine sea salt
  • 0.25 teaspoon freshly-cracked black pepper
  • 2 cups shredded sharp cheddar cheese divided
  • 2 cups diced cooked chicken

Instructions
 

Preparation

  • Heat oven to 400°F.
  • Cook pasta in a large stockpot of generously-salted boiling water until it is al dente. Add the broccoli about 1 minute before pasta is done. Drain both and set aside.
  • Heat butter (or oil) in a large sauté pan over medium-high heat. Add onion and sauté for 3 minutes, then add mushrooms and garlic, sautéing for an additional 5 minutes.
  • Sprinkle flour over the mixture and stir until combined, cooking for 1 minute. Add stock and stir until clumps are gone. Add milk, Dijon, salt, and pepper, stirring until combined. Cook until simmering, then remove from heat and stir in 1 cup cheese.
  • In a 9 x 13-inch baking dish, combine pasta, broccoli, sauce, and chicken. Toss until combined and smooth out into an even layer.
  • Bake uncovered for 15 minutes. Sprinkle remaining cheese on top and bake for 10 more minutes or until cheese is melted.
  • Serve warm, garnished with extra black pepper and/or fresh herbs if desired.

Notes

Any type of pasta will work here. Feel free to use frozen broccoli florets if preferred.
