Mushroom Swiss Roast Beef Sliders

These Mushroom Swiss Roast Beef Sliders are ideal for your next Super Bowl party, family buffet or even random weeknight dinner! I first made these sliders, topped with bubbly Swiss cheese and tangy blue cheese horseradish sauce at supper one night and they were a huge hit with my little family! I love sliders as a meal because they’re much easier for my kids to eat and they’re the perfect portion for them. If your kids are anything like mine, they want to have an entire burger or sandwich, but end up eating only a few bites. Sliders are kid sized, but adults love eating them too. Before we were even done with dinner that night, my husband declared they needed to be served at our next football game gathering. They’re the perfect main course or appetizer, and are really easy to put together!

How to Serve this Easy Appetizer

  • Serve these roast beef sliders plain, with the blue cheese horseradish sauce on the side as a dip.
  • Not sure about the horseradish sauce? Try dipping these little guys in au jus sauce! I like serving them with au jus sauce when I’m making them as a meal because it can be a bit messy for a “grab and go” appetizer.
  • The buttery sauce drizzled over the top of these sliders adds a savory, tangy element to the appetizer.
  • You can add dried minced onion over the top for added flavor (it will taste like the Arby’s onion buns)
  • Speaking of Arby’s, these would be really good with Arby’s sauce! Try our copycat sauce here HERE.
  • If you want to take these to the next level, add some cooked bacon over the roast beef!

Equipment

  • 9×13 inch pan

Ingredients

Blue cheese horseradish sauce:

Instructions

  • Preheat oven to 350 degrees.
  • Spray the bottom of a 9×13 baking dish with cooking spray.
  • Take rolls out of the package.. do not separate them! You want them to be all together. Slice them horizontally through the middle so you have 2 flat slabs.
  • Place the “bottom” slab in the baking dish, set the “top” aside.
  • Saute mushrooms in a medium-sized skillet and set aside.
  • Layer roast beef, sautéed mushrooms, and cheese over the bottom layer. Place the top slab over the top.
  • Combine butter garlic, Worcetershire, and onion powder in a small bowl and mix well. Using a pastry brush, brush butter mixture over the top of the sliders. Cover dish with tin foil and bake for 20-25 minutes or until cheese has melted.
  • While sliders are baking combine sauce ingredients in a small sauce-pot over low heat. Stir often until cheese mixture until cheese is just melted (remove before bringing to a simmer).
  • Remove sliders from oven and serve with sauce on the side (each individual can put a little sauce on their slider).
  • Serve immediately.

    I’m going to make this just so I can have that horseradish sauce LOL! It sounds so delicious with the blue cheese -I see myself using it on everything. Loving these sandwiches!

  2. When you say sliders, I already expect something yum. But when you stuff it with mushrooms and blue cheese, there is no way I am going to miss such recipe 🙂

  3. The sliders that are great on their own. I mean, I could host an entire party with these, and everyone would be delighted. Love how perfect they look!

  4. 5 stars
    Yum these sliders look sooooo good, you had me at “little bites of meaty, cheesy heaven”. Who needs takeout when you can cook waaaay better at home!!

    1. You can do either one– but I usually just get the thin-sliced deli roast because it’s so easy. Hope this helps!
