Make Ahead + Storage Tips:
This casserole can be prepared a day in advance. Assemble the chicken and mushroom sauce in the baking dish, cover tightly, and refrigerate. When ready, bake as directed, adding 5–10 minutes to ensure it’s heated through. Leftovers store well in an airtight container in the refrigerator for 3–4 days. Reheat in the oven at 350°F for 15–20 minutes or in a microwave, then briefly broil the cheese layer for a fresh-baked look.
