I came up with this recipe one day when I needed to use up some mushrooms. It tastes just like a Mushroom Swiss Burger, but maybe better since it’s topped with tater tots instead of a bun!

The meat filling is created with traditional hamburger ingredients I always have on hand – ketchup, mustard, onion. I also included Worcestershire sauce to give it a wonderful robust, savory flavor. It all comes together with some Swiss cheese. If you don’t have Swiss on hand, cheddar would also be tasty!

Speaking of substitutes, if you don’t have tater tots in your freezer, french fries, hash browns or leftover mashed potatoes will work just as well. The key to easy dinners is using what you’ve got.

Even kids will love this dinner if you chop the mushrooms up very small. I’m always a fan of what I call the “veggie sneak.” I don’t have any children yet, but I use it on my husband to increase our vegetable intake. He’s none the wiser, but definitely healthier! 🙂

    Oh I love the look of this! Hungry Hubby would love it too. We can't get tots here so I'd have to improvise but this is very much a recipe I would love to eat :D

    Tots must be a very American thing! What about frozen french fries? This would actually be delicious with rosemary potato wedges.

    Worcestershire Sauce livens up so many meals! My kids would love you for serving Tater Tots! We are definitely fans of 'sneaky veg' here too.
