Ingredient Notes

  • Penne: This recipe calls for penne, but you can substitute with other short pasta like rotini, shells, or ziti. Cook it just until al dente, as it will continue to cook slightly in the oven.
  • Swiss cheese: For the best flavor, use a good-quality Swiss cheese. If Swiss cheese isn’t your favorite, Gruyere is a great substitute.
  • Cooked chicken: Rotisserie chicken works great in this recipe or use leftovers. If you’re using raw chicken, cook it thoroughly before adding it to the casserole.
  • Ham: Leftover ham is perfect for this recipe or you can buy diced or chopped ham in packages, usually near the bacon.
  • Dijon mustard: If you’re out of Dijon, yellow mustard or whole-grain mustard can be used in a pinch.
  • Apple cider vinegar: White wine vinegar or lemon juice can be used as a substitute if necessary.

Sneak in a Veggie

Looking to sneak in a vegetable? One of the best veggies to include is steamed broccoli. You can either mix the broccoli right into the casserole or layer it under the chicken and ham for a hidden surprise that even picky eaters might enjoy. Other great options include sautéed spinach or lightly steamed asparagus. If you’re worried about kids noticing the veggies, chop them finely and mix them in with the sauce; they’ll blend right in!
