Ingredients

For the Burger Patties

• 2 lbs Ground Beef (High quality 80/20 blend for maximum juiciness)
• 2 tsp Kosher Salt
• 1 tsp Freshly Ground Black Pepper
• 1/2 tsp Garlic Powder
• 4 slices Premium Swiss Cheese (thick cut works best)
• 4 Brioche Buns
• 2 tbsp Butter, room temperature (for toasting buns)

For the Savory Mushroom Topping

• 8 oz Cremini or Baby Bella Mushrooms, cleaned and sliced
• 1 medium Yellow Onion, thinly sliced (optional, for that Illinois flair)
• 3 tbsp Unsalted Butter
• 1 tbsp Olive Oil
• 2 cloves Garlic, minced
• 1 tbsp Worcestershire Sauce
• 1 tsp Fresh Thyme leaves

Instructions

Step 1: Fire Up the Grill

1. Start your Arteflame grill by building a wood fire in the center. Allow it to burn down until the center grate is extremely hot (over 600°F) and the outer flat top plancha reaches a medium-high cooking temperature.
2. Lightly oil the flat top cooktop with a high smoke point oil to ensure a non-stick surface.

Step 2: Sauté the Mushrooms and Onions

1. Place the 3 tablespoons of butter and olive oil on a medium-heat section of the flat top.
2. Add the sliced mushrooms and onions. Sauté them, moving them around with a spatula, until they are golden brown and tender (about 8-10 minutes).
3. Stir in the minced garlic, Worcestershire sauce, and fresh thyme. Cook for another minute until fragrant, then move the mixture to a cooler outer edge of the grill to keep warm.

Step 3: Grill the Patties

1. Form the ground beef into 4 equal patties. Make them slightly larger than the buns as they will shrink. Season generously with salt, pepper, and garlic powder.
2. Place the patties directly on the center grill grate for a high-heat sear. Sear for about 2 minutes per side to get a nice crust.
3. Move the patties onto the flat top cooktop to finish cooking to your desired internal temperature (usually another 3-4 minutes for medium).

Step 4: Melt and Assemble

1. While the burgers finish cooking, butter the cut sides of the brioche buns and toast them on the flat top until golden brown.
2. Top each burger patty with a generous heap of the mushroom mixture and cover with a slice of Swiss cheese. You can use a basting dome to melt the cheese quickly.
3. Place the finished patty on the bottom bun, add the top bun, and serve immediately.

Tips for the Perfect Burger

Creating the perfect Illinois-style Mushroom Swiss burger requires attention to detail, especially when working with high-quality beef and fresh ingredients. The secret to a juicy burger is handling the meat as little as possible; overworking the ground beef can lead to a dense, tough texture. When forming your patties, press a small indentation in the center of each one with your thumb. This prevents the burger from puffing up into a ball during the searing process, ensuring it stays flat and cooks evenly. Additionally, manage your heat zones on the Arteflame wisely. Use the intense heat for the initial sear, but rely on the moderate zones of the plancha to melt the cheese without burning the bottom of the patty.

• **Use Cold Meat:** Keep your ground beef in the fridge until the very last moment to ensure the fat stays solid until it hits the grill.
• **Don't Press Down:** Never press the spatula down on the burger while it cooks; this squeezes out the delicious juices.
• **Cheese Timing:** Swiss cheese takes a little longer to melt than American or Cheddar, so add it earlier or use a dome.

Variations

While the classic Mushroom Swiss is a masterpiece on its own, the versatility of the Arteflame grill allows for easy customization to suit different palates. You can lean into the "Illinois" style by adding heavier, steakhouse-inspired elements, or lighten it up with fresh greens. Experimenting with different fungi or adding a textural crunch can completely transform the eating experience. Here are a few ways to twist this recipe while keeping the core flavors intact.

• **The Bacon Crunch:** Add two strips of crispy bacon to the burger for a smoky, salty crunch that contrasts with the soft mushrooms.
• **The Truffle Shuffle:** Drizzle a small amount of truffle oil over the sautéed mushrooms just before serving for an earthy, gourmet aroma.
• **Cheese Swap:** Substitute the Swiss cheese with Gruyère or Emmental for a deeper, nuttier flavor profile.
• **Caramelized Onion Bomb:** Double the amount of onions and cook them slowly on the coolest part of the grill for 30 minutes for a sweet jam-like topping.
• **Slider Style:** Divide the meat into 8 smaller patties and use slider buns for a party-friendly appetizer version.

Best Pairings

A burger this rich and savory deserves sides and drinks that can stand up to its bold flavors without overpowering them. The earthiness of the mushrooms and the creaminess of the Swiss cheese call for beverages that cut through the fat and sides that offer a textural contrast. Since you are already cooking on the Arteflame, it makes sense to utilize the flat top for your side dishes as well. Think crispy, salty, and refreshing to balance the heavy, umami-packed main course.

• **Drink:** A crisp Pale Ale or a medium-bodied Pinot Noir pairs beautifully with the earthy mushrooms.
• **Side:** Grilled sweet potato wedges seasoned with paprika and sea salt.
• **Side:** Charred asparagus spears with lemon zest cooked right next to the burgers.
• **Condiment:** A side of garlic aioli or horseradish cream sauce for dipping.
