Fire up the grill!  These Grilled Mushroom Swiss Burgers are a great way to celebrate warm summer evenings in the backyard!I stumbled across the most accurate quote the other day…on Twitter of all places.

“The 5-second rule doesn’t apply when you have a 2-second dog.” 

So true.  Ethel, our 13-year-old Chihuahua mutt, is as quick as a whip when it comes to food on the floor.  With a 3-year-old Robbie in the house, food somehow just finds its way to the floor.  And guess where she hangs out while we’re eating dinner?  Yup, right under Robbie’s chair.  That Ethel.  She’s no dummy.

Of course, if Robbie realizes he drops food and Ethel gets it?  Oy.  We’re in for a scream fest then.  In fact, that quote should be updated to include a 1-second Dad.  The number of times I’ve dove across the floor to snatch food moments before Ethel chomps down it?  Too many to count.  It’s like a game, and poor Ethel is usually left wondering what happened to that juicy morsel of chicken nugget…or piece of cereal…or saltine cracker.  (Don’t worry.  Ethel gets her fair share of doggy treats and chews.)

I was thinking of that 5-second rule quote the other day when I was outside grilling these Mushroom Swiss Burgers.  Ethel was nearby, smelling the air and keeping a watchful eye on the events happening near the grill.  Each time I successfully flipped a burger, I could almost hear her let out a small 9.5-pound sigh.  Fortunately for me (and unfortunately for her), no rogue burgers escaped to the ground.  Nope, these burgers had bigger goals in mind.  These burgers were destined to become Grilled Mushroom Swiss Burgers.

To Assemble


For the Swiss Cheese Sauce

  • Using a large bowl, add cheese and cornstarch; toss until well combined.
  • Transfer mixture into medium saucepan.
  • Add evaporated milk, smoked paprika and salt; stir and place over medium-low heat.
  • Cook, stirring frequently, for 3-4 minutes, or until sauce is smooth and has thickened noticeably.
  • Reduce heat to low to keep warm until needed.

For the Mushrooms

  • Using a large skillet, add olive oil and place over medium-high heat.
  • Once hot, add onions, mushrooms, salt and pepper; sauté for 5 minutes, stirring occasionally.
  • Reduce heat to medium-low. Add butter and garlic; continue sautéing for 4-5 minutes, or until mushrooms and onions have softened.
  • Remove skillet from heat.

For the Burgers

  • Preheat grill to medium-high heat.
  • Using a large bowl, mix all of the burger ingredients until just combined. Shape into 6 patties and gently indent the center of each patty with your thumb.
  • Brush grill grates with vegetable oil or spray with nonstick grilling spray. Place burgers on the grill; grill for 4-5 minutes per side, or until burgers reach an internal temperature of 160°F.
  • {Optional} Place burger buns cut-side down on grill for 1-2 minutes.
  • Begin assembling burgers by layering lettuce, tomato and patties on top of the buns. Add cheese sauce on top and then top with sautéed mushrooms and onions.

    That’s one fine looking burger. When I read your title, Grilled Mushroom Swiss Burgers and then saw the Swiss cheese sauce I was going, hun. Then I saw the paprika in the recipe. Bingo, that’s where the color was coming from. A nice touch I’m thinking.
    Ethel is one fine looking dog and deserves a treat now and then.
    Boy, do I hear you regarding Ethel and the 5-second rule. Here it’s more like the no second rule. It’s amazing, Chloe dog can be nowhere to be seen, but if a wiener or such drops from the counter it rarely makes it to the floor. When I’m at the BBQ, she’s watching my every move, hoping.
    Don’t you think Ethel needs a brother? You could name him Premium or Unleaded…sorry I couldn’t help myself.

    1. Hah! Laura said the exact same thing, Ron. She was like, uh, Swiss cheese sauce? Why is it yellow? The paprika did it. I promise that Swiss cheese was white when it went in!

      No second rule. I like that! It really is amazing how the pups are off “sleeping” somewhere, but they can hear a tiny morsel of food hit the floor at a mile’s range.

      Hilarious about Premium or Unleaded. Ethel got her name because Laura wanted a quintessential little old lady’s name for her. It matches her personality perfectly, too! 🙂 Thanks so much for the thoughts here, my friend!

    You know what’s funny? Cookie almost never eats food off the floor; even if it’s her food that I spilled, I have to point to it and say EAT! or she thinks it’s off limits. She’s the opposite of every other dog I’ve ever met. If you ever want to loan Ethel out to help me clean my floors I’d love it :). There’s not much I enjoy more than sautéed mushrooms so I’d be allllll over this burger. Have a great weekend and happy Mother’s Day to Laura!

    1. Ahah! So Cookie is a well behaved little pup? That’s good since I imagine the stuff coming off your countertop (ahem, chocolatey goodness) might not be the safest for our 4-legged friends.

      I’m happy to loan Ethel out if you need a good floor cleaning. We joke that her nickname is Hoover. Haha! I hope you had a great Mother’s Day yourself, Kelsie…and I hope Cookie spoiled the heck out of you yesterday! 🙂

    Haha – too funny and so true! Ethel is so cute!! Smart to sit next to Robbie!! This burger looks deadly good, David! All that cheese and mushrooms? That’s what I’m talking about! I could probably eat a burger They’re so good and the options are limitless! Too bad I couldn’t grab that one from my screen! Have an awesome weekend ahead, my friend 🙂

    1. Oh Ethel is no dummy. She knows exactly where to sit to get maximum crumb droppage. There was a time when Robbie would cry if he dropped food and Ethel snatched it up. Now he’s a little more ok with it.

      In other news, this burger. It’s amazing! I’m right there with ya on the burger a day train. If push came to shove, I’d probably say that burgers are my #1 favorite food! I hope you had a great weekend, Dawn, and I hope the weekend involved at least one burger. Haha!

  4. Hi David! This is one fine burger! I like the idea of cheese sauce instead of just a slice. Ethel is SO cute! How could you ever refuse that sweet face? My male dog (who weighs 60 pounds) lies right in the front of the stove when I’m cooking, of course hoping something will magically jump out of a pan!

    1. So I got going on cheese sauces for burgers last summer…they’re amazing! Sure, sliced cheese is so much easier, but if you want something fun then whip up a cheese sauce. I think I could eat the stuff with a spoon! (Ok, maybe with a chip. Haha!)

      Ethel sure is a sweetheart, but you better believe she’s quick as a whip if any food starts heading to the floor. I hope you had a very wonderful Mother’s Day weekend, Dorothy! Thanks so much for stopping by and sharing your thoughts, my friend. 🙂

    My brother feeds his dog all the time and his golden retriever shows it. Your Swiss Burgers look awesome. Mushroom sauce is good on almost anything.

    1. Haha! It’s always easy to spot the spoiled rotten dogs. Ethel is spoiled rotten, too, and we recently put her on a little diet. Granted, her diet was to lose 1/2 pound. But still, we had to keep her in line there! Also, these burgers. Yum!! Thanks so much, Gerlinde!!

    Um . . . yes please! That’s one good looking burger! That melting cheese. Oh my! And what a cutie Ethel is. Happy she made an appearance. When my boys were toddlers we loved that the dogs would clean up the floor after them. 🙂

    1. I got going on cheese sauce for burgers sometime last summer, and now it’s one of my favorites toppings! Sliced cheese is still easier, but if I feel like going the extra step then I’m all about the cheese sauce. 🙂

      Ethel would’ve been all about that cheese sauce, too, if I’d left her alone with it…or dropped it on the floor. Haha! Thanks, Valentina!

  7. Thanks for sharing a funny story; also Ethel is so cute. But I must confess I couldn’t really focus on reading because I kept thinking about these amazing burges. The combo of mushrooms, cheese, and smoked is so welcoming, right? The idea of using evaporated milk for the sauce is rather interesting, too – I guess it makes it even more decadent and silky. Well done!

    1. Hah! I understand that one, Ben. I often can’t focus when I’ve got burgers in front of me, too. 🙂 And, yes, this cheese sauce is amazing. It’s quick and easy, and you can use the leftovers as queso with some tortilla chips! Thanks so much, my friend!

    Oh, Ethel! What a cutie! And that is one smart dog – she knows the best place to be 😉
    I don’t have a dog, but I do have two cats. Whenever I am cooking with pork, they go crazy…. they are so obsessed with pork!

    This burger looks delicious! My Mum, in particular, is a huge fan of mushrooms- I might just have to make this for her tomorrow for Mother’s Day 🙂

    1. No way! Pork? That’s hilarious about your cats and pork. Ethel isn’t too picky, but she really loves (I mean LOVES) when I bake bread. She circles around my feet like you wouldn’t believe!

      I love a good burger, and these sauteed ‘shrooms plus that cheese sauce combined for one heck of a tasty meal. Thanks so much, Alexandra!

  9. ethel is such a sweetheart! so cute and clever too she knows where to sit to grab th goodies. i love mushrooms and this burger looks so absolutely delicious. yummo! cheers sherry

    1. Oh, Ethel is no dummy. She knows exactly where to sit to maximize the chances of something coming her way…and that’s right under Robbie! If you love mushrooms, then you absolutely need to put this burger on your summer grilling agenda, Sherry. It’s definitely a good one! Thanks so much, my friend!

    1. Yes! As far as I’m concerned, you can’t have too any burgers in the grilling rotation. 🙂 Thanks so much, Christie!!

    Ethel is so cute! Do you think she would like to become friends with our cat Begbie? As long as they could get on well being cat and dog there are always treats on the go here as its usually me accidentally dropping food from the recipes I’m experimenting with in the kitchen! Love this cheesy mushroom burger combination. 🙂

    1. So I’m thinking Ethel and Begbie could be friends. I dunno, though. Sometimes Ethel gets scared of her own shadow. Haha!

      These cheesy ‘shroom-y burger turned out quite well. I’m so glad grilling season is finally back! (Of course, as I say that we’re currently experience a cold, rainy day here in New York. Ick.) Thanks so much, Neil!

  11. David! With a fantastic-looking burger! It looks like if I bit into it, that juices and chhese would just run down all over my chin, which is the best kind of burger.

  12. WOA -What an epic burger! I’m betting I couldn’t fit that in ma pie hole to take a bite! So love the grilled mushrooms on there AND the epic giveaway!
    BTW, I am all too familiar with the dash across the room/floor to get to a morsel of food not meant for a dog – I have two and as soon as I start chopping anything, they perk up and are ready to grab whatever may fly off! Happy Monday my friend!

    1. Oh, these burgers didn’t last too long here, Shashi! In fact, I piled on extra mushrooms when I sat down to eat this bad boy. 🙂

      It’s hilarious with dogs and dropped morsels of goodness. Ethel is nowhere to be seen, but if a piece of food hits the floor? She magically shows up in a heartbeat!

    1. Oh, you might think a single Cheerio would fill her up…but that pup knows how to eat! In fact, we had to put her on a diet recently. She needed to lose 1/2 pound. 🙂 Thanks so much, Kathy!

    1. Haha, oh I even surprise myself sometimes, Kelly! It’s like a 6th sense kicks in, and my arm just instantly shoots out to catch whatever morsel might be about to go into Ethel’s mouth. 🙂

      Also, these burgers. Oh man, these are a good one for summer grilling! That cheese sauce on top really these to the next level. Thanks so much, my friend!

    I’m cracking up at your 1-second dadness, David! I can just see you diving for the food with Robbie and Ethel looking on…lol!

    This burger looks truly epic! Bring on grill season!

    1. Oh man, I think I developed a 6th sense once Robbie was born. If food starts falling to the floor, my arm just immediately shoots out without me even thinking about it. Kinda funny!

      And I second the ‘bring on the grill’ idea! I’m ready for summer! 🙂
