Does In-N-Out Contain Soy? Your Guide to Navigating the Menu

According to official nutritional information, several core items at In-N-Out, including the buns, cheese, and famous spread, contain soy derivatives. This makes it essential for individuals with soy allergies to understand exactly what to avoid and how to modify their orders to prevent exposure.

Quick Summary

In-N-Out's menu contains soy in its buns, American cheese, and signature spread. However, it's possible to custom order soy-free meals by using lettuce wraps and omitting certain ingredients. Fries are cooked in soy-free sunflower oil.

Key Points

• Soybean Oil: The famous In-N-Out spread contains soybean oil, making it a primary source of soy.

• Burger Bun: The buns are also not soy-free, as they contain soybean oil.

• Soy Lecithin: The American cheese contains soy lecithin, which acts as an emulsifier.

• Safe Fries: The french fries are a safe option, as they are cooked in 100% sunflower oil.

• Protein Style: Ordering 'Protein Style' with a lettuce wrap is the best way to get a soy-free burger bun.

• Custom Ordering: You must specify 'no spread' and 'no cheese' to eliminate all soy from your burger.

Primary Sources of Soy at In-N-Out

Understanding where soy is hidden is the first step toward a safe meal. For those with a soy allergy, three main components of a standard In-N-Out burger are the primary concern: the bun, the spread, and the cheese.

The Burger Buns

In-N-Out's buns are not soy-free. As explicitly detailed in their official nutrition information, the bun ingredients include enriched wheat flour alongside soybean oil. This means that for anyone avoiding soy, the standard bun must be avoided entirely.

The Signature Spread

The famous In-N-Out spread, a key component of their classic burgers, also contains soy. The ingredients list specifies soybean oil and/or canola oil. Since soybean oil is a significant component, the spread is a major source of soy and must be omitted from any soy-free order.

The American Cheese

Even the classic American cheese at In-N-Out is a potential source of soy. The ingredients list includes either soy or sunflower lecithin as an emulsifier. While the lecithin is often highly processed and may not trigger a reaction in all individuals with soy allergies, the possibility of soy contamination exists. It is safest for those with a serious allergy to also omit the cheese.

Soy-Free and Safe Ordering Options

Fortunately, it is still possible to enjoy a meal at In-N-Out if you have a soy allergy. The key is to know which substitutions to make.

Here are some safe, soy-free menu choices and modifications:

• Protein Style Burger: This is the best option for a soy-free burger. By requesting your burger 'Protein Style', the bun is replaced with a hand-leafed lettuce wrap, completely eliminating the soy from the bun.
• No Spread and No Cheese: When ordering your Protein Style burger, be sure to request 'no spread' and 'no cheese'. The spread contains soybean oil, and the cheese contains soy lecithin.
• French Fries: In-N-Out's french fries are a safe side dish. They are made from fresh potatoes and cooked in 100% sunflower oil in a dedicated fryer.
• Shakes and Beverages: The shakes are made with real ice cream, and beverages are generally safe, but it's always wise to confirm if there's any concern. According to allergen information, the main allergens in shakes are milk.
