Burger King Impossible Whopper (September 2026): Real Price & Calories
The Impossible Whopper swaps the beef patty for a plant-based Impossible patty, keeping the rest of the standard Whopper build. It runs about $7.25 on average and 670 calories, and it’s not vegan by default, mayo and shared-broiler cooking both get in the way unless you ask otherwise.

Ingredients
The Impossible patty itself: Water, Soy Protein Concentrate, Coconut Oil, Sunflower Oil, Natural Flavors, Methylcellulose, 2% Or Less Of: Potato Protein, Yeast Extract, Cultured Dextrose, Food Starch Modified, Soy Leghemoglobin, Salt, Soy Protein Isolate, Mixed Tocopherols (Vitamin E), Zinc Gluconate, Thiamin Hydrochloride (Vitamin B1), Sodium Ascorbate (Vitamin C), Niacin, Pyridoxine Hydrochloride (Vitamin B6), Riboflavin (Vitamin B2), Vitamin B12. On the sandwich: sesame seed bun, lettuce, tomato, pickles, onion, ketchup, and mayonnaise — the same toppings as a regular Whopper. Soy leghemoglobin is the key ingredient: it’s a protein derived from soy plants that mimics the heme found in animal meat, giving the patty its meat-like taste, aroma, and the way it changes color when cooked.
Is It Actually Vegan or Vegetarian?
Not by default. Two things get in the way: the standard build includes mayonnaise (egg-based), and it’s cooked on the same broiler as beef patties, so cross-contact is possible. To get as close to vegan as BK allows: (1) ask for no mayo, and (2) request separate cooking — most locations can oven-heat or microwave the patty instead of using the shared broiler. BK does not guarantee a fully vegan product even with both steps, but this is the best available protocol. It works fine as vegetarian either way. Don’t confuse it with the Veggie Whopper off-menu hack, that one’s just a Whopper with the patty removed, no plant-based patty involved at all.
Impossible Whopper vs. Regular Whopper
| Feature | Impossible Whopper | Regular Whopper |
|---|---|---|
| Patty | Plant-based (soy) | Beef |
| Calories | 670 | 710 |
| Protein | 32g | 34g |
| Fat | 35g | 42g |
| Carbohydrates | 64g | 57g |
| Sodium | 1,490mg | 1,250mg |
| Price | ~$7.25 | ~$6.15 |
| Cholesterol | 15mg | 90mg |
The real health story is cholesterol: 15mg vs 90mg — 83% less. That’s a meaningful difference for anyone watching cardiovascular risk. The calorie and fat gap is smaller than most people expect (40 fewer calories, 7g less fat), and it actually runs higher in sodium (1,490mg vs 1,250mg) and carbs. Taste-wise, the condiments, bun, and flame-grilled char do most of the work — the patty difference is mainly a slightly different aftertaste, not a texture gap. Choose it for the plant-based source and the cholesterol drop, not for a dramatic calorie save.
Allergens
| Component | Allergen |
|---|---|
| Impossible Patty | Soy (gluten-free since 2019 reformulation) |
| Bun | Wheat, sesame |
| Mayonnaise | Egg |
Important allergen notes: The Impossible patty itself is gluten-free, but the sandwich is not — the bun contains wheat and sesame. If you need gluten-free, order the patty alone or on a lettuce wrap.
The plant-based patty is safe for alpha-gal syndrome (no mammalian meat), but cross-contamination from the shared beef broiler is a risk — request separate cooking (oven or microwave) if you have this condition.
The Impossible patty is halal certified (IFANCA, since 2018) and kosher certified (OU). No dairy in the patty or standard toppings (without cheese).
Frequently Asked Questions
670 for the sandwich alone, roughly 1,310 as a meal with medium fries and a medium Coke.
Not by default — it includes mayonnaise (egg-based) and is cooked on a shared broiler with beef. To get as close to vegan as possible: (1) ask for no mayo, and (2) request separate cooking (oven or microwave). BK does not guarantee a fully vegan product even with both steps.
Close. The soy leghemoglobin in the patty replicates the taste and color of cooked beef, and the condiments, bun, and flame-grilled char do most of the heavy lifting — the main giveaway is a slightly different aftertaste, not a texture gap.
The biggest win is cholesterol: 15mg vs 90mg (83% less), which matters if you’re watching cardiovascular risk. Calories and fat are only modestly lower (40 fewer cal, 7g less fat), and sodium is actually higher (1,490mg vs 1,250mg). A real but mixed improvement, not a dramatic health upgrade.
The patty is gluten-free (since Impossible Foods reformulated in 2019), but the sandwich is not — the sesame seed bun contains wheat. Order the patty alone, on a lettuce wrap, or ask your location about gluten-free bun options.
Yes. The Impossible patty is halal certified by IFANCA (since 2018) and kosher certified by the Orthodox Union (OU). The standard toppings (lettuce, tomato, pickles, onion, ketchup) are also halal and kosher — skip the mayonnaise if egg is a concern for your observance.
What To Do Next
Check the BK app first: the Choose 2 for $6 deal makes the Impossible Whopper cheaper than a solo Regular Whopper at menu price. Want more protein? The Impossible Texas Whopper has 42g. If you’re choosing between the Impossible and the Regular Whopper on health, the cholesterol drop (83% less) is the real win — calories and fat are only modestly different. For vegan ordering: no mayo plus separate cooking is the best available protocol. See the full Whopper lineup or start from the complete BK menu.
