Whataburger Breakfast on a Bun Ingredients

This item starts with a soft small white bun made from enriched wheat flour, water, yeast, and soybean oil, giving it a light texture and slightly sweet taste. The bun also contains a small amount of high-fructose corn syrup, salt, and dough conditioners that help keep it fresh and fluffy. It includes wheat, soy, and sesame allergens and contains a bioengineered food ingredient. The bun is lightly brushed with bun oil, which is made from soybean oil and added flavorings to enhance taste and maintain quality.

Inside the bun, there is a fresh USDA Grade AA extra-large egg, cooked to provide a rich and satisfying bite. A crispy hash brown, fried in soybean oil, adds a crunchy texture, while a slice of small American cheese made from milk and cream melts smoothly, adding a mild and creamy flavor. The sandwich also includes a pork sausage patty, seasoned with salt, natural spices, and flavor enhancers, delivering a savory and hearty taste.

To bring everything together, it is topped with a creamy pepper sauce, made from soybean oil, vinegar, egg yolks, buttermilk, spices, dried chilies, and garlic. This sauce adds a bold, slightly spicy, and tangy flavor and contains egg and milk allergens. The item is finished with a simple special seasoning of salt and pepper, enhancing the overall flavor without overpowering the ingredients.
