I always look forward to that first scoop where the creamy cheddar melts perfectly with savory ham and sweet peas. One time my youngest got to help sprinkle the cheese on top and declared it the best dinner ever which made it all the more special.
Storage Tips
Store any leftovers tightly covered in the refrigerator for up to four days. Reheat single servings in the microwave with a splash of milk to keep the casserole creamy. For longer storage cool completely then wrap tightly and freeze. It will keep well for about three months and can be reheated directly from frozen.
Ingredient Substitutions
You can swap turkey or cooked chicken for ham depending on what you have. Cream of mushroom or cream of celery soup works instead of cream of chicken for a different flavor profile. For glutenfree needs use certified glutenfree soup and doublecheck other ingredients for safety.
Serving Suggestions
Pair this casserole with a crisp green salad or steamed broccoli for some fresh greens. Warm garlic bread or soft dinner rolls are great alongside to scoop up extra cheesy sauce.
