About the Texan BBQ King
The Burger King Texan BBQ King has no price published by Burger King in its restaurant data and carries 996 kcal. Two juicy, flame-grilled beef patties topped with iceberg lettuce, crispy onions, sliced onions, pickles, melted cheese and a creamy, peppery BBQ mayo paired with a sweet and smoky Texan BBQ sauce, served in a soft, glazed sesame seed bun. It sits in the flame grilled burgers section of the UK menu, alongside 14 other items.
On the numbers it gives you 53g of protein, which is 106 percent of a day's reference intake, 59g of fat, 22g of it saturated, 3.1g of salt, 52 percent of the 6g daily maximum, 13g of sugar. Salt is the line to notice: 3.1g out of a 6g day, spent on a single item and before any fries join it.
On calories it lands 348 kcal above the flame grilled burgers average of 648 kcal. The closest thing to it on the whole menu is Large Ben & Jerry's Chocolate Fudge Brownie at 1017 kcal, which is a useful swap to know if you want the same sort of number in a different form.
The declared allergens are soya, celery. It may also contain gluten, wheat, milk, egg, sesame, mustard through shared preparation, which matters more than the headline list if you are avoiding something strictly. All of that is published by Burger King UK under the fourteen allergen rules. It says nothing about how any one restaurant handles preparation, which is worth asking about directly for a serious allergy.
Paired with something else, Bacon Caesar Angus at £8.09 and WHOPPER with Bacon and Cheese at £5.99 sit in the same section and are the obvious companions. Whether that lands where you want it is a question for the calorie calculator; the full menu has the rest of the prices.
