- Place the fries on a cookie sheet and bake them in an oven.
Now, take a pan and add white sauce in it. Heat it over medium flame, sprinkle the cheese and stir till it forms a creamy sauce. (You can make white sauce at home by adding two-three tsp white flour to cold milk and then letting it simmer on low flame till it thickens. Season it with salt and pepper.)
Once the fries are done, season them and pour the sauce over the fries while serving. Serve hot!
