#1: The 3×3 Burger – A Protein Lover’s Dream
At the top of our list is the 3×3 burger, a towering masterpiece that takes In-N-Out’s classic Double-Double to the next level. As the name suggests, this secret menu item features three juicy beef patties stacked high, each topped with a slice of American cheese, crisp lettuce, ripe tomatoes, and the signature spread. It’s a carnivore’s paradise and a must-try for anyone looking to indulge in a hearty meal.
What sets the 3×3 apart from its simpler counterparts is its sheer size and flavor profile. The additional patty adds a depth of savory goodness that elevates the entire experience, while the layers of cheese create a gooey, melt-in-your-mouth texture. Despite its heft, the burger remains balanced thanks to the fresh produce and soft, toasted bun. For those who crave bold flavors and aren’t afraid of a challenge, the 3×3 is a game-changer.
To order this beast of a burger, simply tell the cashier you’d like a “3×3” and specify whether you want it with cheese (most people do). Keep in mind that this item is not officially advertised, so don’t be surprised if your server confirms your order before ringing it up. If you’re feeling adventurous, consider pairing it with Animal Style fries for the ultimate feast.
#2: The 4×4 Burger – Pushing the Limits of Flavor
If the 3×3 wasn’t enough to satisfy your cravings, the 4×4 burger takes things even further.

The extra layers allow for more surface area to soak up the signature spread, creating a harmonious blend of tangy, savory, and slightly sweet notes. And let’s not forget the fresh toppings, which provide a refreshing contrast to the richness of the meat and cheese. Whether you’re sharing it with friends or tackling it solo, the 4×4 is sure to leave a lasting impression.

The beauty of the Flying Dutchman lies in its simplicity. Without the bun, the focus shifts entirely to the quality of the ingredients. The beef patties are cooked to perfection, with a slight char that enhances their natural juiciness.
