National Great American Pot Pie Day is observed worldwide every September 23. This informal food-related holiday was created in 2002 by Marie Callender's, a company known for its pot pies and frozen foods. The day celebrates the pot pie, a dish typically characterized by a meat filling topped with a crust, often made of puff pastry. To commemorate the occasion, people are encouraged to enjoy a pot pie, either by purchasing one or making it at home. A simple chicken pot pie recipe includes ingredients such as diced chicken breast, green peas, carrots, celery, and a creamy sauce, all baked in a pie crust. This holiday highlights the enjoyment of comfort food and culinary traditions associated with pot pies.
