The Complete Definitive List of All White Castle Secret Menu Items

White Castle is the quintessential fast food restaurant. It was made famous after appearing in the Harold and Kumar franchise. The cult classic stoner movie follows two guys who get high and then go to White Castle, among other adventures. White Castle's sliders are probably the most well known item on the regular menu. Customers can purchase the original slider by the sack, crate, and case. Other fast food burger restaurants like Burger King, McDonalds, and Wendy's have secret menu items, but none hold a candle to the White Castle's secret menu. Read on for these secret menu items and thank us later.

White Castle Secret Menu Items

Surf and Turf Slider

Just like the name implies, this is a play on lobster and steak. This slider has a fish fillet and two beef patties. It's served with melted American cheese and chopped onions.

Grilled Cheese

The grilled cheese slider is a great hack for vegetarians and meat eaters alike. It's normally served with cheddar cheese, but if you want to spice it up, ask for jalapeno cheese.

Super Loaded Fries

This item is actually a super hack from the regular loaded fries. Loaded fries start with regular crispy French fries, topped with bacon crumbles, melted cheese, and ranch. To amp this up to super loaded, add BBQ sauce, onion chips, and chopped tomatoes.

Bacon Crumbles

This isn't a secret, but you can add bacon crumbles to any item White Castle sells. The only thing that could possibly make White Castle burgers better is bacon. For bacon lovers, this is not only delicious, but possibly life changing.

Loaded Mozzarella Sticks

This White Castle secret menu item is almost identical to the super loaded fries, except with mozzarella sticks. Order your sticks, then order bacon crumbles, ranch dressing, and BBQ. Feel free to ask for onion chips as well. To really blow your mind, order the loaded mozzarella sticks and the loaded fries and knock yourself into a food coma.

Neapolitan Shake

This milkshake gets its name from Neapolitan ice cream. It the best of 3 worlds, combining chocolate, vanilla and strawberry together in a giant shake masterpiece. If you're more of a purist, go for the black and white milkshake, which combines half chocolate with half vanilla.

Three Cheese Waffle Slider

This secret menu item ups the ante from the regular grilled cheese by being served on a Belgian waffle.

Impossible Double

White Castle was actually the first fast food chain to offer an impossible patty. A standard cheeseburger is delicious, but this is perfect for vegetarians. For vegetarians, we suggest ordering a double cheese slider and subbing in the Impossible patty.

Valentine's Day Special

Is there anything in the world more romantic than sharing White Castle? We certainly don't think so. After starting as a marketing ploy in the 90's, people have come to love this Valentine's tradition. Order ten sliders, two 21-ounce sodas, and a side of fries. It's the perfect meal to share with someone you love.

Harold and Kumar's Order

If you want to recreate the famous movie, first order 30 sliders, 5 French fries, and 4 large cherry Cokes. Next, order 30 sliders, 5 French fries, and 4 Diet Cokes. If that doesn't fill you up, we don't know what will.

Chicken Parm Slider

This White Castle secret menu item requires some DIY-ing. Order a crispy chicken breast slider and mozzarella sticks. Add the sticks and the accompanying marinara sauce to the chicken slider and enjoy. The cheese from the mozzarella sticks melts perfectly to recreate chicken parm.

Cowboy Slider

White Castle has many great sliders, but the chicken sandwich isn't it. It definitely doesn't hold a candle to Chick-fil-A or KFC. The cowboy slider helps to change all of that. Order your favorite chicken slider or chicken rings with jalapeno cheese. Add a side of onion rings and BBQ sauce. Add the rings to your chicken and top with the tangy sauce. Voila, you now have a wonderful and spicy chicken sandwich.
