REVIEW: Burger King Mushroom & Swiss Big King

Burger King Mushroom & Swiss Big King

I thought what made Burger King’s Big King special was its middle bun AND the thousand island-style dressing. It turns out I’m as wrong as the guy who bids $75,000 for a Price is Right Showcase that consists of a year’s supply of sunscreen, two jet skis, a trip to Hilo, Hawaii, and a 2014 Kia Forte.

With the release of Burger King’s Mushroom & Swiss Big King, I learned the special sauce isn’t so special. I also learned the middle bun is the crown that make a Big King a Big King.

In case you can’t see everything in that blob of fast food ingredients above, the Mushroom & Swiss Big King features two beef patties, sautéed mushrooms, a slice of Swiss cheese, mayonnaise, a sesame seed bun, and the important middle bun.

Mine also ended up with a rogue slice of American cheese, but there’s no thousand island-style dressing. Of course, I’m pretty sure adding a sweet and tangy sauce to a mushroom and Swiss burger would’ve been gross.

And now that we know it’s the boring middle bun that makes a Big King a Big King and the thousand-island dressing isn’t there to stifle creativity, I expect Burger King to create many Big King variations in the future. Perhaps the Whopper has passed the variety burger baton to the Big King, so we’ll soon be seeing a Rodeo Big King, a Texas BBQ Big King, and a Western Big King.

Burger King Mushroom & Swiss Big King Topless

As you can see above, the burger is loaded with mushrooms. Okay, maybe you can’t see them all in that overzealous application of mayonnaise. But I assure you there were a lot of them because I could feel all the mushroom rubberiness in my mouth.

When I ate the Burger King Mushroom & Swiss Grillers back in the 2011, I complained about it having too much mushroom flavor. But with the Mushroom & Swiss Big King, I’m going to complain about it having too little mushroom flavor. Yes, there was some here and there, but with that many mushrooms, I expected almost every bite to taste like I was nibbling on Papa Smurf’s house.

I’m going to blame the mayo.

While the mayonnaise does a great job at preventing mushrooms from falling out of the burger and making the Swiss cheese slice feel more melted than it really is, it also does a good job at making this burger taste more like a mayonnaise and Swiss burger than a mushroom and Swiss burger. Having less mayo might’ve helped, but those sad, rubbery mushrooms didn’t have a lot of flavor to begin with.

Overall, the Burger King Mushroom & Swiss Big King is a mediocre burger and I think someone should take away its crown. It’s not horrible because the beef patties had a pleasant meatiness to them, and even with all that mayo, the sandwich wasn’t messy. But it tastes like a simple double cheeseburger that accidentally had a few mushrooms dropped onto it during the lunch rush.

Pros: Lots of mushrooms. Mayo does a great job at preventing mushrooms from falling out. Decent beef patties with good flavor. Winning a Price is Right Showcase.
Cons: Lots of mushrooms don’t have lots of flavor. Mayo does a great job at preventing mushroom flavor from standing out. The middle bun being the reason why a Big King is a Big King. Going over when bidding on a Price is Right Showcase.

  1. That’s very much in line with my memory of the value-menu mushroom-Swiss burger that BK did a couple years ago. It wasn’t actively bad, but I never felt the urge to buy another one, and it somehow harshed my mellow for making the trek to BK at all.

  2. Well, if that doesn’t look nasty, I don’t know what does. Mayonnaise has ruined many a sandwich over the years. Burger King should dial down the mayo gun. They could probably drop the prices with all the money they’d save.

  3. I agree BK uses too much mayo on the mushroom swiss, but the problem with the few BK’s around here that I visited is that they hardly give you any mushrooms. I had to stress several times to give me extra mushrooms for them to actually give me a decent amount. I’ve had this sandwich 4 or 5 times and I like it. No, the mushrooms aren’t like fresh, but I didn’t find them rubbery. Other than today, the mushrooms seem to be in some kind of “mushroom” sauce. I probably wouldn’t order it as often if I was paying regular price (about $4), but as part of the 2 for $5 menu I think it’s a great deal.
