Store Friendsgiving Pie Party pies in covered pie containers or airtight boxes in the refrigerator for up to 4 days. You can freeze individual slices for up to 2 months by wrapping each piece in plastic wrap and placing them inside a freezer bag. Avoid freezing pies with fresh whipped cream because the topping texture changes after thawing. Reheat slices at 300°F for 10 to 15 minutes until the crust feels crisp again. Add fresh whipped cream or a small spoonful of yogurt after warming for better texture. Discard any pie with sour odors, watery separation, or mold spots because those changes mean the dessert is no longer safe to enjoy.
