Make-Ahead and Prep Tips

One of the great things about this Chicken, Spinach and Mushroom Bake is that it can be prepped ahead of time. You can assemble the entire dish up to a day in advance. Simply cover it with plastic wrap and store it in the refrigerator until you’re ready to bake. When you’re ready to enjoy it, increase your cooking time by about 5-10 minutes to account for the cold ingredients.

How to Store Leftovers

Leftovers are a great benefit of this dish! Store any uneaten Chicken, Spinach and Mushroom Bake in an airtight container in the refrigerator for up to 3 days. For longer storage, you can freeze leftovers for up to 3 months. When you’re ready to enjoy your frozen bake, simply transfer it to the refrigerator to thaw overnight, then reheat gently in the oven until warmed through. Look for the cheese to get bubbly to ensure it’s perfectly heated.
