Yes! To make ahead, do not preheat your oven, and prepare the white chicken enchiladas through Step 4 (below). Cover tightly and store in the fridge until you're ready to bake the enchiladas. When ready, take the enchiladas out of the fridge and let them sit on the counter at room temperature while you preheat your oven to 350 degrees. Bake at 350 for 25 minutes or until cheese bubbles.
