FAQs

How do I get my fries extra crispy?

To achieve extra crispy fries, bake or fry them slightly longer than the package suggests, or double-fry them if making them from scratch.

What is the best cheese for Animal Style Fries?

American cheese is the classic choice due to its smooth melting quality, but cheddar, Monterey Jack, or a cheese blend can also work well.

Can I make the special sauce ahead of time?

Yes, the sauce can be made ahead and stored in the refrigerator for up to a week. This allows the flavors to meld together for an even better taste.

Can I use fresh potatoes instead of frozen fries?

Absolutely. Cut fresh potatoes into thin strips, soak them in cold water for 30 minutes, then fry or bake until crispy.

How do I prevent the onions from burning?

Cook them over low to medium-low heat and stir frequently. If they start browning too quickly, reduce the heat and add a splash of water.
