Ingredients

  • Cooked chicken: the star of the dish tender and soaks up the Alfredo sauce well use rotisserie or leftover roasted chicken for best flavor

  • Grated Parmesan cheese: brings umami depth opt for freshly grated for the sharpest flavor
  • Frozen peas: brighten the casserole and add a hint of sweetness pick vibrant green peas for freshness or leave out if you prefer

My favorite ingredient here is Parmesan because its nutty flavor deepens as it bakes My kids always sneak a corner piece with extra cheese and it reminds me of growing up when the cheesiest piece was first to go

Storage Tips

Let the casserole cool completely before covering tightly and refrigerate Right before reheating splash in a spoonful or two of milk and cover with foil This keeps everything creamy and stops the top from getting too dry

Ingredient Substitutions

Swap in chopped broccoli instead of peas for an earthier vibe Use whole wheat or gluten free pasta to fit your needs If you like a little kick toss in a sprinkle of chili flakes or a touch of nutmeg into the Alfredo sauce

Serving Suggestions

Serve with a crisp green salad and crusty bread for a complete meal For extra color add halved cherry tomatoes on top before baking This dish also shines at potlucks and family gatherings
