Prepare the french fries based on the package instructions. You can either bake, fry or air fry the french fries.
While the fries are cooking, prepare the sauce and fried onions.
Mix the sauce ingredients together in a small bowl.
Melt the butter in a large skillet over medium high heat. Then top the melted butter with the chopped onions. Sauté the onions in the butter until they are caramelized (3-5 minutes).
Then place the fries on a plate, cover with the American cheese slices, caramelized onions and the sauce.
Serve immediately while warm and enjoy!
Notes
These fries are best served fresh. You can refrigerate the sauce in an airtight container for up to 1 week.
