Tips and Tricks
Control the heat - Buffalo sauces vary quite a bit in spiciness. Choose a mild version for less heat or a hotter sauce if you like a little more kick.Use plain leftover turkey - Turkey that has already been mixed with gravy or heavily seasoned may change the flavor and consistency of the dip.Make it ahead - Assemble the dip up to 24 hours ahead of time, cover, and refrigerate. Bake when you're ready to serve. It may need a few additional minutes in the oven if it's cold from the refrigerator.Keep it warm for parties - Transfer the baked dip to a small slow cooker on the warm setting for serving. Stir occasionally to keep the cheese mixture creamy.
Storing and Reheating
Refrigerator - Transfer leftover dip to an airtight container and refrigerate promptly. Use within 3 to 4 days of when the turkey was originally cooked, not 3 to 4 days after making the dip.Microwave - Place a serving in a microwave-safe bowl and heat in 30-second intervals, stirring between each, until hot throughout. Heat to 165°F.Oven - Place the dip in an oven-safe dish, cover with foil, and heat at 350°F until it reaches 165°F. Stir before serving.Texture After Reheating - The Greek yogurt may release a little liquid after refrigeration. Stir the dip well after reheating to bring it back to a creamier consistency.
