Is Burger King’s Impossible King Vegan?

Burger King Impossible King

Burger King just announced that June 27th, 2022 they will be launching two new Impossible Burgers to their menu; the Impossible King and the Impossible Southwest Bacon Whopper.

So immediately, I wondered what most vegans were probably wondering, “Are these new Burger King Impossible Whoppers vegan?”

This answer, of course, is kind of. Let me explain.

Burger King’s Impossible Whopper

We’ve gone in-depth here at VeggL regarding what our viewpoint is on whether or not the original Impossible Whopper is vegan. To sum it up, we believe that since no animals are being harmed then we consider it vegan. If you have an issue with the cross-contamination (it shares a grill with meat products) then we totally understand that as well. We give you the information, you choose your level of comfort. 

You also have the option to ask them to not cook the Impossible Burger on the grill. I believe they microwave it. 

Now that that is out of the way, let’s focus on the new Impossible King.

The Impossible King – Is it Vegan?

The Impossible King will consist of an Impossible plant-based patty, topped with American cheese, sliced white onions, pickles, ketchup and mustard on a toasted sesame seed bun.

This means all you’ll need to do is order the Impossible King with NO cheese and you’re good to go!

Of course, the same cross-contamination concerns that have been present with the original Impossible Whoppers will also still be there. You can ask for them to cook your Impossible burger in the microwave.

If you’re thinking that the Impossible King sounds suspiciously similarOpens in a new tab. to the Impossible Whopper already on the menu, you’re not far off.

So, exactly what is the difference?

The Impossible King has swapped out the mayo for mustard and added cheese. So, instead of ordering an Impossible Whopper with no mayo, it will be an Impossible King with NO cheese.

This means once it’s all said and done, what we’re actually getting is an Impossible Whopper with added mustard. We’re not totally sure yet whether or not the Impossible King is replacing the Impossible Whopper or if it’s being added to the menu in addition too. I guess we’ll find out in a couple of days.

The Impossible Southwest Bacon Whopper

The other new Impossible Burger being added to the menu is the Impossible Southwest Bacon Whopper. This whopper will come with an avocado spread, seasoned tortilla strips, bacon and a spicy sauce.

If you go for this option you’ll need to order your Whopper with NO bacon, cheese or spicy sauce.

Which New Impossible Burger is Better?

This is a question that I personally can’t wait to attempt to answer, but at the time of this writing, we’re still a few days out from Burger King’s new Impossible Burgers hitting the menu. Rest assured that I’ll be updating this page on June 27th, once I get a chance to try out both of these new options.
