About the Plant-based WHOPPER

The Burger King Plant-based WHOPPER costs £6.19 and carries 528 kcal. A flame-grilled plant-based burger, topped with tomatoes, fresh cut lettuce, vegan mayo, pickles, a swirl of ketchup, and sliced onions on a soft sesame seed bun. *Plant-based WHOPPER® is plant-based, however it is cooked on the same broiler as our beef WHOPPER® to deliver the same unique flame-grilled taste. It sits in the vegan and vegetarian section of the UK menu, alongside 2 other items.

A single serving carries 27g of protein, which is 54 percent of a day's reference intake, 24g of fat, 4.5g of it saturated, 2.5g of salt, 42 percent of the 6g daily maximum. Salt is the line to notice: 2.5g out of a 6g day, spent on a single item and before any fries join it.

Divide 528 kcal by its 278g and you get around 190 kcal per 100g. That makes it typical of the menu around it, so weight and satisfaction track each other here.

Against the rest of the vegan and vegetarian range it ranks as the most expensive item in the section. Nothing costs less than Halloumi Fries at £4.49, and nothing costs more.

On calories it lands 86 kcal above the vegan and vegetarian average of 442 kcal. If the count matters more than the craving, Vanilla Milkshake lands in the same place at 531 kcal.

The ingredient list carries no declared allergen at all. The cross contact list carries 9: gluten, wheat, milk, egg, soya, sesame, celery, mustard, sulphur dioxide. For a preference the first list is the one to read. For a genuine allergy it is the second, every time. Both lists come from the brand's own data against the fourteen allergens UK law requires restaurants to declare, and practice varies between branches, so confirm at the counter for anything serious.

If you are building a full order, Vegan Royale at £6.19 and Halloumi Fries at £4.49 sit in the same section and are the obvious companions. Add them up on the calorie calculator before ordering, or check the running cost against the full price list.

How to Make a Plant-based WHOPPER at Home

A home Plant-based WHOPPER is mostly about checking labels. The patty is the easy part; buns and sauces are where dairy and egg usually sneak in.

Tips

  • Season the patty on the outside. Plant based mixes are usually seasoned already, so taste before adding more salt.
  • Vegan mayonnaise browns differently and can split if it goes near direct heat. Keep it on the cold side of the build.
  • The Vegan Society mark on a packet is a stricter check than a plant based label, which only describes the ingredients.

Variations

  • Add vegan cheese and smoked plant based rashers.
  • Swap the shredded lettuce for rocket if you want something with more bite.
  • Use a wholemeal bun to lift the fibre without changing the build.

Fries cooked in a separate pan of oil, so nothing shares with meat, and a cold drink.

Plant-based WHOPPER Questions

A Plant-based WHOPPER costs £6.19 at a standard Burger King restaurant in the UK. That is the standard high street figure. Travel hub branches run their own higher list, and every delivery app prices above the restaurant menu before fees.

The Plant-based WHOPPER contains 528 kcal, which is 26 percent of a 2,000 kcal day. Compare it against the rest of the vegan and vegetarian range, where the average lands at 442 kcal.

It carries 2.5g of salt. UK guidance sets the adult limit at 6g a day, so this is 42 percent of the daily maximum from one item. Sides and dips add to that faster than most people expect.

Most people pair it with fries and a drink. From the same section, Vegan Royale and Halloumi Fries are worth a look. The sides page covers what each addition costs and adds.

Most branches carry it, but the vegan and vegetarian range is one of the areas where smaller sites cut back. The Burger King app shows the live menu once you select a restaurant, which is the only reliable way to check before travelling. The store locator lists every UK branch.
