Mushroom & Swiss Sliders with Spicy Fry Sauce

I am definitely not a burger person at all, but I decided to make these sliders because my husband was begging me for a burger.  I've never actually made any kind of burger before this besides microwaving a Boca Burger...sad, but true.  These sliders are some of the best cheeseburgers I've ever had!  I believe they have changed my opinion on cheeseburgers, and I will certainly be making them again.  Thank you Pioneer Woman!

First, you will make the spicy fry sauce.  Here are your ingredients:

Here's what the sauce should look like after mixing.  Do not add as much cayenne if you are not big on spicy food.  I like spicy food, and it had a kick to it even for me!  Put the sauce in the refrigerator until ready to use.

Here is the ingredient line-up for the sliders:

Next, you will make the mushroom topping.  Throw some butter in the skillet to melt.

Then add the onion and cook until translucent, about five minutes.

Add the mushrooms and wine.

Here is what it should look like after the wine is totally evaporated.

Remove the mushroom mixture and set aside.  Then push an indentation in each hamburger patty, so they won't plump up too much, and place in the same skillet used for the mushroom mixture.  Cook for a few minutes on each side.

When meat is cooked to your liking, top each slider with the mushroom mixture and swiss cheese.

Cover the skillet with a lid and let cheese melt for a couple minutes.

Serve on a warm roll and top with spicy fry sauce....heaven on a plate.

Mushroom and Swiss Sliders with Spicy Fry Sauce


  • ⅓ cups Mayonnaise
  • 2 Tablespoons Ketchup
  • 1 teaspoon Cayenne Pepper (less If You're Sensitive To Spice!)
  • 4 Tablespoons Butter
  • ½ whole Medium Onion, Finely Diced
  • 8 ounces, weight White Mushrooms, Chopped Finely
  • ½ cups White Or Red Wine
  • 4 dashes Worcestershire Sauce
  • Kosher Salt And Freshly Ground Black Pepper
  • 2 pounds Ground Beef
  • 4 Tablespoons Heavy Whipping Cream
  • 4 dashes Worcestershire Sauce
  • 1 teaspoon Kosher Salt
  • Freshly Ground Black Pepper
  • 4 slices Swiss Cheese, Cut Into Four Squares
  • 8 whole Dinner (or Slider) Rolls, Split

Preparation Instructions

In a small bowl, mix mayonnaise, ketchup, and cayenne. Stir together until totally combined. Set aside. (This is the spicy fry sauce.)
Melt butter in a large skillet. Add onions and cook over medium heat for five minutes, stirring frequently. Add mushrooms and toss around, then add wine, Worcestershire, salt and pepper. Cook for several minute over medium heat, or until all liquid has evaporated. Transfer mushroom mixture to a separate bowl, scraping all contents from the skillet.
Mix ground beef, heavy cream, Worcestershire, and salt and pepper in a bowl. Use your hands to thoroughly mix ingredients. Form 1/4 to 1/3 cup of the meat mixture into patties, making an indentation with your thumb to keep the patties from plumping too much when they cook. In the same skillet as the one used to cook the mushrooms, melt 1 tablespoon butter over medium to medium-high heat. Add four patties at a time, indented side face up. Cook for 4 minutes, then flip. Spoon generous portion of mushroom mixture on each patty, then top with one or two squares of Swiss, depending on your preference. Place lid on skillet and cook for an additional 2 to 3 minutes, until burgers are cooked through and cheese is melted. Remove to a place and keep warm while you repeat with the rest of the meat mixture.
Toast halved buns under the oven broiler. Spread generously with spicy fry sauce. Place patties between buns and serve immediately.

  2. I think this sauce looks super yummy for other things - like french fries too?? I LOVE sauces of all sorts. Ooooh maybe chicken also?

  3. It would be fantastic with french fries or chicken fingers! Thanks for the idea!
