This super simple and easy recipe for chicken Alfredo casserole is a great choice for dinner. Make it as directed or alter it as you'd like. In cooking recipes, you can use different meats, different pastas, and different cheeses and seasonings and the recipe will still work fine. 

For ideas, use a four-cheese Alfredo sauce or use a couple of cans of cream of "whatever" soup. You can also add more cheese, or add frozen sliced carrots, peas, or asparagus. Use your imagination! Just make sure you write down the changes after you have made the recipe (and have decided that you like it) so you can reproduce it in the future.

There are only five ingredients in this tasty dish, so it can be assembled in minutes. In fact, you can make it ahead of time and refrigerate it up two days before you bake and serve it.

Serve this great casserole with a green salad tossed with sliced mushrooms and grape tomatoes or avocados, and some toasted garlic bread or cheese bread for some crunch. Iced tea or white wine would be a great accompaniment. And for dessert, an apple pie or a cheesecake from the bakery would be the perfect finishing touch.

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.

You can vary this dish in many ways: add 1 cup sliced frozen carrots, thawed, 2 cups frozen baby peas, thawed, 1 (10-ounce) package frozen asparagus, thawed, 2 cups frozen green beans, thawed. Or top the casserole with 1/3 cup bread crumbs mixed with 3 tablespoons melted butter; add that after the casserole is uncovered.
