The Burger King Bacon Double Cheese XL costs £7.99 and carries 910 kcal. Two flamed-grilled beef patties topped with Applewood smoked bacon and American cheese, all in our toasted sesame seed bun. It sits in the flame grilled burgers section of the UK menu, alongside 14 other items.
A single serving carries 63g of protein, which is 126 percent of a day's reference intake, 52g of fat, 24g of it saturated, 3.8g of salt, 63 percent of the 6g daily maximum, 8.2g of sugar. The salt is what makes this hard to pair, because most of what sits beside it on the menu adds more of the same.
At 316g the Bacon Double Cheese XL works out at roughly 288 kcal per 100g. That makes it about average for hot fast food, so the portion size is a fair guide to how filling it is.

On calories it lands 262 kcal above the flame grilled burgers average of 648 kcal. If the count matters more than the craving, Texan BBQ Double Royale lands in the same place at 922 kcal.

A home version of the Bacon Double Cheese XL comes down to two things: real charring heat and a patty you have barely touched. The build itself is straightforward once those are right.
Serve it with fries and a pickle on the side rather than another salad.

The Bacon Double Cheese XL contains 910 kcal, which is 46 percent of a 2,000 kcal day. UK guidance sets the adult average at 2,000 kcal for women and 2,500 for men, so judge it against the whole day rather than the meal.
