National Cheddar Fries Day is celebrated every April 20, primarily in the United States. This holiday invites people to indulge in the delicious combination of crispy French fries topped with melted cheddar cheese, often enhanced with toppings like bacon, jalapeños, and chives. The dish, a variation of cheese fries, gained popularity in the early 1950s with the introduction of Cheese Whiz by Kraft Foods. National Cheddar Fries Day has been observed annually since 2016, founded by Snuffer’s Restaurant and Bar in Dallas, which claims to offer the original cheddar fries made from hand-cut Idaho potatoes and aged Wisconsin cheddar. Observers can enjoy cheddar fries at various restaurants or make their own at home, and social media engagement is encouraged using the hashtags #NationalCheddarFriesDay and #CheddarFriesDay.
