The Foundation of Your Keto Order

Achieving a delicious keto meal at In-N-Out is all about starting with the right foundation: the bun-less burger. There are two primary ways to do this, both part of the famous "secret menu": Protein Style and the Flying Dutchman.

Ordering "Protein Style"

Protein Style is the most common keto modification and is known to all In-N-Out employees. Instead of a bun, your burger is wrapped in large, crisp iceberg lettuce leaves. This keeps all the classic ingredients together in a surprisingly sturdy and fresh package. You can order any burger Protein Style, from a simple hamburger to a massive 4x4. The lettuce provides a satisfying crunch and freshness that helps compensate for the missing bun. It's a game-changer for anyone on a low-carb diet who doesn't want to compromise on taste.

Embracing the "Flying Dutchman"

For the most hardcore keto diners, the Flying Dutchman is the way to go. This ultra-simple order consists of just two beef patties with two slices of cheese in the middle. It comes served in a small paper tray, often with a fork and knife, making it an easy and mess-free meal. Some locations will even fry the patties with mustard upon request, adding extra flavor without any carbs. The Flying Dutchman is the ultimate no-fuss, high-fat, high-protein option.

Customizing Your Keto In-N-Out Burger

Once you have your base, it's time to build your perfect keto burger with a variety of approved toppings. Being specific with your order is key to avoiding hidden carbs.

Toppings and Condiments to Add

  • Mustard: A classic choice, mustard is a zero-carb condiment that packs a flavorful punch. Request it fried onto the patties for an extra layer of taste.
  • Onions: Both raw and grilled onions are keto-friendly, though grilled onions will add a slight sweetness. Raw onions provide a sharp, fresh flavor, while grilled onions become soft and caramelized.
  • Pickles: Add a tangy crunch with pickles, a standard low-carb topping.
  • Tomatoes: A slice or two of tomato adds freshness and moisture to your lettuce wrap.
  • Yellow Chili Peppers: For those who like a little heat, In-N-Out's famous yellow chili peppers are a fantastic, zero-carb addition.

What to Avoid on Your Keto Trip

To keep your meal strictly keto, you must be vigilant about what you leave off your burger. High-carb items are abundant in fast-food settings, and In-N-Out is no exception. Avoid these items entirely:

  • The Bun: This is the most obvious one. Always order "Protein Style" or "Flying Dutchman".
  • The Spread: In-N-Out's famous Thousand Island-like spread contains sugar and carbs. Ask for "no spread". As an alternative, a packet contains about 2g of carbs, so you can control your portion if you choose.
  • Ketchup: Like the spread, ketchup is high in sugar. Stick to mustard or bring your own sugar-free alternative.
  • French Fries: The delicious, fresh-cut fries are a carb bomb and not part of a keto diet. Skip them entirely.
  • Shakes and Sugary Drinks: All shakes and sodas contain a large amount of sugar. Opt for water, unsweetened iced tea, or a diet soda.

Ordering "Animal Style" the Keto Way

The "Animal Style" burger is a fan favorite, and it can be made keto-friendly with a simple modification. Animal Style includes grilled onions, extra spread, and mustard fried patties. To make it keto, you simply need to request "Protein Style, Animal Style, no spread." This will give you the delicious mustard-fried patties and grilled onions without the sugary sauce.
