The Mushroom and Swiss Steakhouse Burger from Burger King

There’s not many mushrooms… but otherwise it’s a solid big burger.

How many of you have succumbed to the countless terrible television commercials for Burger King’s new Mushroom and Swiss Steakhouse Burger? BK has made a mockery of Simon and Garfunkel. How dare they! Well, even those awful commercials were not enough to deter me from trying this new behemoth. Available for a limited time only, this burger offers up a new taste and unique ingredients worth trying.

The ‘Shroom and Swiss is a large flame-grilled Angus beef patty, mushrooms, Swiss cheese, crispy fried onions and A1 brand steak sauce. I don’t usually care for mushrooms on my burgers, so I was a little wary, but I’m glad I gave this sandwich a fair shot. If you’re not crazy about the idea of ’shrooms on your hamburger, I think you’ll be pleasantly surprised. They are very, very subtle, and there’s not many of them. Just enough to add a tiny bit of extra flavor. Of course if you’re a mushroom lover hoping for a big payoff, you’ll be disappointed by their small numbers, so buyer beware.

The flame-grilled Angus beef tastes good, and it’s huge, overhanging the bun. The patty is not exactly round, it’s more a rectangle shape. The tasty bun is corn dusted but maybe a tad undersized for the load it has to carry. There’s a good amount of melted Swiss cheese, though it’s mild enough to not be overpowering. The sharp tangy taste of the steak sauce gives this sandwich a different character than typical burgers, and it’s a nice match for BK’s blend of Angus beef. The sauce and crunchy fried onions are my favorite parts of the unique ingredients, but everything works in harmony.

I’ve ordered this burger twice and one thing that I immediately noticed both times was how greasy they were. Literally, there were pools of grease left behind after I was done eating. So be aware of the potential mess you are getting into, especially if you’re on-the-go. Also, the corn dusted bun will shed its corn dust all over the place, and there’s a TON of melted Swiss everywhere. Price wise, this burger is definitely on the expensive side. At $7.49 for the combo, and $5.09 for the sandwich alone, you might find a better deal elsewhere. To it’s credit, it’s a big hearty meal for the money.

So… if you’re a big mushroom lover, be warned there’s not many. However, if you’re tastes are similar to mine, this might be just the right amount. Your reaction to that point will determine whether it’s worth a shot. I was happy with this burger, but admit my expectations were not very high, and I found a small amount of mushrooms to be a good thing. I don’t see this sandwich being around much longer. It’s expensive and probably won’t be a big seller. While it’s still available, I recommend trying it, obviously not on the strength of it’s mushrooms, but just a big beefy burger with good tasting meat, cheese, crunchy onions and steak sauce. It’s a solid flavor combination.

  1. This review is right on. I am a big mushroom lover and the mushrooms on this burger do not have a lot of flavor. I’m also not crazy about the A1 Sauce. It is messy, but overall, this is a pretty good burger.

  2. Given that I don’t really enjoy mushrooms on a burger, this sandwich does not appeal to me at all. it’s overly expensive and looks like a really greasy and a sloppy eat. I hope it goes away soon!

  3. I like the idea behind this burger. It looks good.

    BUT when something has “mushroom” in the name I would expect to get more.

  4. I generally dislike Burger King, even by fast food standards.

    They’re just sloppy and the veggies are usually rotten or missing.

    I ordered this burger once on a whim and I was very dissapointed.

  5. […] Fast Food Critic reviews BK’s Steakhouse Mushroom & Swiss burger. […]

  6. I’ve seen this commercial a gabillion times so far - I was actually going to go try it, but thanks for the heads up on low shroom count. That would be pretty disappointing since I’m a fan of them on burgers.

  7. omg. great burger , i could eat this every day. i found that one of the bks in town put alot of shrooms on them and the other bk puts very few. but you can ask for extra and it works every time. my only prob now is that its not a the bk close to my house. they just told me today they werent gonna sell it anymore. i hate when they bring somethin out and then i love it and they dont sell it anymore. wendys got me with the bacon cheddar burger and quit and mcdonald with the mcrib and now bk with shroom and swiss burger. i think its a great deal , everything has gone up price wise so why not pay to get a fullfilling burger

  8. I ate one of these things on a lark and developed a mild case of pancreatitus due to the high fat content.

    The ironic thing was after I had just ordered it I was looking at the nutritional info on thier wall poster and thought to myself this is probably NOT a good idea.

  9. I have not eaten all day and it was after 5pm and passed a BK on my way home. I have not eaten here in years so I bought a steak burger meal and it was like $7 bux dang!
    I ate a few frys and then took out this huge burger. It looked real good and at the time I was starved! I took a few bites and it was great. I noticed it had WAY too much mayo so I took the bun and wiped some off. I continued eating a few more bites and almost done but say 2 1/2 bites left and felt like barfing! lol.. I through it in the bag and through the rest away. I was too full too fast and felt sick. I went home and could not eat or drink a thing the rest of the evening and I worked all night. Thinking about it now I regret putting that huge greasy thing in my body and will NEVER eat that again.

  10. I tried this burger for the first time–but I asked for it to me made with the garden burger instead. I really liked this combination and it probably came to a fraction of the calories and fat.
