What Ingredients You Will Need

This recipe uses straightforward, wholesome ingredients to build a burger that’s juicy, flavorful, and satisfying without any fuss. Most of these are pantry staples or easily found at your local grocery store. Here’s what you’ll need:

• For the Beef Patties:
  • Ground beef (80/20 blend recommended for best juiciness) – 1 lb (450g)
  • Salt and freshly ground black pepper – to taste
  • Vegetable or canola oil – 1 tbsp (for griddle)
• For the Mushroom Topping:
  • Cremini or white button mushrooms, sliced – 8 oz (225g) (adds earthy umami)
  • Unsalted butter – 1 tbsp (for sauté)
  • Garlic cloves, minced – 2 (fresh flavor boost)
  • Fresh thyme leaves – 1 tsp (optional, but recommended)
  • Salt and pepper – to taste
• For the Cheese and Assembly:
  • Swiss cheese slices – 4 (I like Emmi or Boar’s Head for meltability)
  • Brioche buns or your preferred burger buns – 4 (toasted on the griddle)
  • Optional toppings: caramelized onions, lettuce, tomato slices, pickles, mustard, or mayo

Feel free to swap out mushrooms for a mix of cremini and shiitake in fall months for a richer flavor. If you want a dairy-free option, try a plant-based cheese alternative or omit cheese. Brioche buns toast up beautifully on the Blackstone, adding just the right buttery crunch. You can also check out a simple keto grilled chicken Greek salad recipe if you want a fresh side to balance the richness.

Equipment Needed

• Blackstone Griddle: This is key for achieving the perfect sear and smash on your burgers. If you don’t have a Blackstone, a large cast iron skillet or flat-top griddle works too.
• Metal Spatula or Burger Press: Essential for smashing the patties thin and scraping the griddle clean between batches. I prefer a sturdy metal spatula with a sharp edge.
• Cutting Board and Chef’s Knife: For slicing mushrooms and prepping toppings.
• Mixing Bowl: To season and gently mix the ground beef before forming into portions.
• Small Skillet or Griddle Section: For sautéing mushrooms separately from the patties to control texture and flavor.
• Tongs: Handy for flipping burgers and handling buns on the griddle.

If you’re budget-conscious, a cast iron skillet can substitute well for the Blackstone, though you might miss that extra surface area for cooking multiple patties at once. Keeping your spatula sharp and the griddle well-seasoned will make smashing and flipping a breeze.

Preparation Method

1. Prep the Mushrooms: In a small skillet over medium heat, melt 1 tablespoon butter. Add sliced mushrooms, stirring occasionally, until they release moisture and start browning—about 6-8 minutes. Add minced garlic and thyme during the last 2 minutes, then season with salt and pepper. Set aside and keep warm.
2. Preheat the Blackstone Griddle: Heat your Blackstone on high until it’s very hot, about 5-7 minutes. Brush the cooking surface lightly with vegetable oil to prevent sticking.
3. Form and Season Patties: Divide the ground beef into 4 equal portions (~4 oz or 115g each). Gently form into loose balls without overworking the meat. Season generously with salt and pepper on all sides just before cooking.
4. Cook and Smash Patties: Place one beef ball on the griddle. Using a metal spatula or burger press, smash down firmly to about ¼-inch (0.6 cm) thickness. Cook for 2-3 minutes until edges are deeply browned and crispy. Flip carefully and cook for another 1-2 minutes.
5. Add Swiss Cheese: Immediately after flipping, place a slice of Swiss cheese on each patty. Let the cheese melt as the second side cooks.
6. Toast the Buns: While the cheese melts, place buns cut-side down on a cooler section of the griddle to lightly toast for 1-2 minutes. Watch closely to prevent burning.
7. Assemble the Burgers: Place the cooked patties on buns, top with sautéed mushrooms, and add any optional toppings like caramelized onions or pickles.
8. Serve Warm: Serve immediately for the best juicy, melty experience.

Tip: If you notice the mushrooms drying out, add a splash of water or broth during sauté. Also, pressing too hard or too early can squeeze out juices from the beef, so press firmly once and let the patty cook undisturbed for a crispy crust.

For a variation on this technique, you might enjoy the rich flavors in my savory cast iron garlic butter steak bites with mushrooms, which share that mushroom love but in bite-sized form.

Cooking Tips & Techniques

Smash burgers on a Blackstone griddle are all about timing and technique. Here are a few things I’ve learned the hard way:

• Don’t overwork the beef: Handle the ground beef as little as possible before cooking. This keeps your patties tender, not dense.
• Heat is everything: Your Blackstone should be screaming hot before the patties hit the surface. This heat creates that irresistible crust.
• One firm press: Smash each ball once to the desired thickness. Avoid pressing repeatedly, or you’ll lose juicy bits.
• Keep the mushrooms juicy: Sauté mushrooms low and slow to keep them tender and flavorful. Adding garlic and thyme elevates the taste beautifully.
• Don’t skip toasting the buns: Toasting on the griddle adds texture and flavor, plus it helps prevent sogginess from the mushroom juices.
• Work in batches: Don’t crowd the griddle. Cook 2-3 patties at a time for even heat and browning.

I remember a time when I tossed mushrooms straight on the burger patty during cooking—big mistake! They got soggy and overwhelmed the beef flavor. Cooking them separately and layering on top made all the difference.

Variations & Adaptations

This mushroom and Swiss smash burger recipe lends itself well to tweaks, whether you’re catering to dietary needs or just craving a flavor twist.

• Vegetarian Mushroom Burger: Swap out beef patties for thick portobello mushroom caps seasoned and grilled on the Blackstone. Use vegan Swiss-style cheese to keep that melty goodness.
• Spicy Kick: Add sliced jalapeños or a chipotle mayo spread for some heat. Alternatively, mix a pinch of cayenne pepper into the beef before forming patties.
• Low-Carb Option: Use lettuce wraps instead of buns to keep it keto-friendly. Pair this with the easy low-carb bacon cheeseburger casserole for a full meal plan.
• Seasonal Mushroom Mix: Swap cremini mushrooms for a wild mushroom blend in fall and winter for richer earthiness.
• Cheese Swap: Try gruyere or smoked gouda instead of Swiss for a different flavor profile.

I once tried adding caramelized shallots to the mushroom mix—wow, that was a game-changer! The sweetness cut through the savory beef perfectly.

Serving & Storage Suggestions

Serve these savory mushroom and Swiss smash burgers hot off the griddle for best flavor and texture. They pair wonderfully with crispy fries, a fresh side salad, or even grilled veggies. For a lighter side, a crisp cucumber or tomato salad complements the richness well.

Leftover burgers can be wrapped tightly in foil and refrigerated for up to 2 days. Reheat gently on the Blackstone or in a skillet to keep the crust crispy and cheese melty again. Avoid microwaving if you want to preserve that texture.

Toast buns separately upon reheating to prevent sogginess. The mushrooms will keep their flavor but best eaten within a day for freshness.

Over time, the mushrooms’ umami deepens, making the leftovers even more flavorful the next day. If you want a lighter meal, try pairing the burger with a simple side like my creamy vegan loaded sweet potato bowls for a fresh twist on comfort food.
