Prepare the gravy first. It can either be kept warm on the stove or heated again when the fries are ready.
Whisk the cornstarch into the chicken broth until fully incorporated - no lumps - then set this aside.
Melt the butter over medium heat in a large saucepan. Whisk in the flour and allow that to cook for about 5 minutes.
Gradually whisk in the beef broth, parsley, garlic powder, onion powder, and pepper. Then whisk in the chicken broth, cornstarch mixture. Allow this to come to a boil. Then turn down the heat and allow it to simmer, uncovered, for another 10 minutes, or until the desired thickness is reached, stirring every couple of minutes. Add salt to taste.
While the gravy is simmering, pour your oil into a wide saucepan and heat it on high. Deep fry the french fries in batches so they are not crowded. Fry them at about 300°F for 5 minutes. Remove them from the oil and place them on a paper towel allowing them to drain and cool. Fry them a second time for about 5 minutes (or until golden brown). The double fry will give them a nice crispy texture. If you didn’t use seasoned fries, salt the fries lightly after frying. Double frying is an important step! You may feel like it’s unnecessary, but it gives the fries an extra crispy layer so when you pour your gravy over top, they don’t become soggy!
Place the fries into a serving dish. Sprinkle the cheese curds over the fries. Then pour the gravy over top. You can stir this up lightly with tongs. Serve immediately.
