All the delicious flavors of your favorite chicken Cordon Bleu--salty ham, melty cheese, tangy mustard--with no tricky assembly required. Healthier comfort food that’s easy for weeknights.


  • 2 cups chopped broccoli florets
  • 8 oz whole-wheat fusilli (gluten-free pasta if you’re avoiding gluten)
  • 2 Tbsp butter
  • 1 lb boneless, skinless chicken breast, cut into ½" pieces
  • 1 small onion, chopped
  • salt and pepper
  • 3 Tbsp all-purpose flour (any flour will work great)
  • 2 Tbsp Dijon mustard
  • 2 cups milk (nut milk if you're avoiding dairy)
  • 1 cup shredded Swiss cheese
  • 1 cup diced ham (~ 4 oz)
  • ½ cup chopped fresh parsley

Rustic Herbed Bread Crumbs

  • 3 - 4 slices bread, torn into small pieces (gluten-free if you're avoiding gluten)
  • ¼ cup fresh parsley leaves
  • 1 Tbsp fresh thyme leaves
  • ¼ cup butter, melted but not hot


Rustic Herbed Bread Crumbs

  • Combine bread, parsley, and thyme in a food processor; pulse until coarsely chopped.
  • Transfer to a bowl, toss with melted butter. Set aside.


  • Preheat oven to 375° F.
  • Put a large pot of water on to boil. Cook broccoli in the boiling water until just tender and bright green, about 3 minutes. Transfer to a large bowl with a slotted spoon.
  • Add pasta to the boiling water and cook according to package directions. Drain and rinse with cold water. Transfer to the bowl with the broccoli.
  • Heat butter in a large skillet over medium heat. Add chicken, onion, salt, and pepper. Cook, stirring frequently until the onion has softened and the chicken is no longer pink throughout (~ 6- 8 minutes)
  • Add flour and mustard. Stir until coated. Add milk and bring to a boil. Cook, stirring until thickened slightly (~ 3-5 minutes)
  • Transfer to the bowl with the broccoli and pasta. Stir in cheese, ham, and parsley. Transfer the mixture to a 9-by-13-inch baking dish, spreading evenly.
  • Bake until the casserole is heated throughout and the breadcrumbs are beginning to brown, about 30 minutes (or 50 minutes, if casserole has been frozen).
  • Preheat broiler to high. Sprinkle top of the casserole with herbed bread. Broil on rack 8 inches from heat until the top is browned (~ 2 to 3 minutes)
