Mushroom Swiss Sliders Recipe

I’m thrilled to share my take on slider sandwiches featuring rich ground beef with finely chopped white onion and butter-sautéed mushrooms. Nestled between sweet dinner rolls and crowned with a silky Swiss cheese sauce, every bite is a celebration of savory flavors balanced perfectly with just the right touch of salt and black pepper.

I recently came up with these Mushroom Swiss Sliders that totally changed the game for my slider recipes. I’ve always been a fan of cheeseburger sliders, but these ones felt so different with a twist of savory and sweet.

I started with a lb of perfectly seasoned 80/20 ground beef mixed with a small white onion that I finely chopped, then sizzled in a pan with a bit of salt and freshly ground black pepper. Adding 8 oz of sliced button mushrooms and a couple of tablespoons of unsalted butter really took it to the next level.

Then I piled all this goodness onto sweet dinner rolls and drizzled a homemade Swiss cheese sauce made from shredded Swiss cheese, whole milk, and a bit of all-purpose flour, along with a pinch of salt and white pepper. I cant wait for you to try these sliders so you’ll discover a new twist on your favorite burger treats.

Enjoy and experiment!

Why I Like this Recipe

I love how the beef, mushrooms and Swiss cheese sauce all come together to create a really amazing flavor explosion in every bite. I also like that this recipe is simple enough to follow so I can whip it up on a busy day without stressing too much. The way the mushrooms add a savory kick makes these sliders way more interesting than your everyday burger. And, I have to admit, the sweet buttered dinner rolls give a nice contrast to the savory beef and melted cheese that I just can’t get enough of.

Ingredients

• Ground beef: Packed with protein and flavor, its fat renders and gives mouthwatering richness.
• White onion: Adds a sweet kick and crunch, plus a gentle dose of fiber.
• Mushrooms: Their earthy umami taste boosts the sliders while keeping calories low.
• Swiss cheese: Smooth, nutty flavor melted into the sauce creates a creamy surprise.
• Whole milk: Provides the sauce a silky texture and enriches every bite.

Ingredient Quantities

• 1 lb ground beef (80/20 blend)
• 1 small white onion, finely chopped
• Salt, to taste
• Freshly ground black pepper, to taste
• 8 oz button or cremini mushrooms, sliced
• 2 tbsp unsalted butter
• 6-8 sweet dinner rolls
• For the Swiss cheese sauce: 1 cup Swiss cheese, shredded or thinly sliced
• 1 cup whole milk
• 1 tbsp all-purpose flour
• A pinch of salt and a pinch of white pepper
• Optional: fresh parsley for garnish

How to Make this

1. Preheat your oven to 350°F so your rolls get a nice toasty warmth while your patties cook.

2. In a bowl, combine the ground beef, finely chopped onion, salt and pepper and mix it up just until its all combined, then form small slider-sized patties.

3. Heat a skillet over medium-high heat and add the patties. Cook them for about 3-4 minutes on each side until they’re browned and cooked through.

4. In the same skillet add the butter and let it melt, then toss in the sliced mushrooms. Cook the mushrooms for about 5-7 minutes until they are soft and a bit browned.

5. While your patties and mushrooms are cooking, set a small saucepan over medium heat and whisk the flour into the whole milk until smooth.

6. Bring the milk to a gentle simmer and then add the Swiss cheese. Stir until the cheese is melted and the sauce gets thick, then season with a pinch of salt and a pinch of white pepper.

7. Once the rolls are warmed in the oven for about 5 minutes, slice them open so they’re ready for the sliders.

8. Start building each slider by placing a beef patty on the bottom half of a roll.

9. Top the patty with a generous spoonful of those flavorful mushrooms then drizzle on some of that irresistible Swiss cheese sauce.

10. Cap it off with the top of the roll, garnish with a little fresh parsley if you like, and serve immediately while it’s hot. Enjoy these yummy Mushroom Swiss Sliders!

FAQ

Mushroom Swiss Sliders Recipe Substitutions and Variations

• If you dont have ground beef, you can try ground turkey or even ground chicken instead.
• If you cant find a small white onion, a yellow onion would work or a little drop of onion powder.
• Instead of using button or cremini mushrooms, you could use portobello or shiitake mushrooms for a different taste.
• If unsalted butter is not on hand, a good quality margarine can be a decent alternative.
• For the Swiss cheese sauce, Gruyere cheese is a nice substitute if you cant get Swiss cheese.

Pro Tips

1. A tip that really helps is to mix your ground beef just until it comes together. Overmixing it can make the patties kind of tough, so be careful not to work it too much.
2. When you’re making the Swiss cheese sauce, keep the heat low and stir all the time so that the sauce doesn’t burn or get lumpy. It helps to whisk constantly so it’s smooth and tasty.
3. For the mushrooms, let them get nice and browned in the butter because that really brings out their flavor. If you add a little extra salt a few minutes in, it makes a big difference.
4. Toasting the rolls extra for a couple of minutes can give you that perfect crisp on the outside and soft inside. It adds a really good texture overall when you put everything together.
