Frozen meatballs are available in a variety of flavors. Plain meatballs are used in this pie, but Swedish meatballs with subtle spices and Italian meatballs with a heartier flavor can also be used.
Thaw the meatballs overnight in the refrigerator, or use the Defrost setting on your microwave to quickly thaw them.
The standing time for this pie, like many egg-based dishes, allows the pie to set up before being cut.
Savory Impossibly Easy Pies can be covered and refrigerated up to 24 hours before baking. You may need to bake a bit longer than the recipe directs since you’ll be starting with a cold pie. Watch carefully for doneness.
