For those looking to enjoy a classic In-N-Out burger with a low-carb, gluten-free twist, the answer to "what does In-N-Out use for protein style?" is simple: fresh, hand-leafed lettuce. Instead of the standard toasted bun, the burger patties and all the delicious toppings are carefully wrapped in large leaves of crisp lettuce. This clever customization has become a staple of the fast-food chain's famous "secret menu," catering to various dietary needs without compromising flavor.

The Anatomy of an In-N-Out Protein Style Burger

A Protein Style burger includes all the familiar components of a regular In-N-Out burger, just held together differently. The preparation begins by taking a large, fresh head of iceberg lettuce and carefully separating the leaves. These sturdy, crisp leaves are then used as the wrapper, encasing the ingredients to be eaten by hand. Because the lettuce itself has very little flavor, it allows the classic taste of the fresh beef patty, secret spread, cheese, and vegetables to shine through.

The most common protein style orders are the standard single hamburger or a Double-Double, though almost any burger can be ordered this way. The assembly process is straightforward: the spread is placed on the bottom lettuce leaf, followed by the beef patty (or patties) with melted cheese, and then topped with fresh or grilled onions, tomatoes, and pickles, before being wrapped neatly.

Nutritional Benefits of a Protein Style Order

One of the main reasons for the popularity of the Protein Style burger is its lower carbohydrate count. By swapping the bun for lettuce, a significant number of calories and carbs are eliminated from the meal. For example, a single Protein Style hamburger has considerably fewer carbs than its bun-based counterpart. This makes it an appealing option for those following low-carb diets, such as keto, or those needing a gluten-free meal due to celiac disease or gluten sensitivity.

Beyond just cutting carbs, the protein style option also offers a few other nutritional perks:

  • Lower Calorie Count: Eliminating the bun reduces the overall caloric intake of the meal.
  • Higher Protein-to-Carb Ratio: The name "Protein Style" refers to the shift in macronutrient ratios, with the meal containing proportionally more protein and fat relative to carbs.
  • Freshness: The focus on fresh ingredients, especially the vegetables, is emphasized. For those who enjoy the crispness of lettuce and fresh tomatoes, the lettuce wrap can actually be a more refreshing experience.

Customizing Your Protein Style Burger

The fun doesn't stop at just swapping the bun. Because it's part of the secret menu, a Protein Style burger can be combined with other popular customizations to create a truly personalized experience. Some common options include:

  • Animal Style: Get your Protein Style burger with mustard-fried patties, extra spread, and chopped grilled onions.
  • With Grilled Onions: Add a sweet, savory flavor by requesting grilled onions.
  • Add Chopped Chilies: For a kick of heat, you can have chopped chilies added.
  • No Spread: For those managing fat intake, you can order your burger without the signature sauce.
