Notes

*You can use ziti, penne, or any short pasta shape in this recipe.

**It's best to steam fresh, not frozen broccoli. Freshly steamed broccoli will hold its shape better than frozen.

***I used pan-seared chicken breasts, but baked chicken thighs will also work. A store-bought rotisserie chicken is also great in a pinch.

Becky's Top Tips:

To make the smoothest, creamiest Alfredo sauce, make sure to use full-fat cream cheese that has been brought to room temperature. Cook it over low heat, and stir frequently to prevent burning.
If your Alfredo sauce is too thick, add a bit more room temperature half-and-half to thin it back out.
Mixing warm ingredients helps the sauce coat evenly and prevents it from seizing or clumping when combined. I like to rewarm the chicken and broccoli before mixing.
When steaming the broccoli, aim for it to be just under. It will finish cooking in the oven.
The same with the pasta -- cook it to al dente!
You can add some spinach or peas to this dish easily. Just fold them in!
Don't forget to broil the casserole for just a few minutes to get that wonderfully browned mozzarella top! Keep your eye on it as it broils though, because it can quickly go from golden browned to burned.

Make-Ahead: Assemble the casserole up to the cheese topping, then refrigerate for up to 24 hours. Bake covered for 10 minutes longer before broiling.

Storage: Store chicken broccoli Alfredo in an airtight container in the refrigerator for up to 3 days or in the freezer for up to 3 months.
