A juicy, flame-grilled beef burger topped with melted Swiss cheese, savory sautéed wild mushrooms, and fresh greens, all served on a toasted artisan bun. Rich, hearty flavors and gourmet ingredients make this burger a restaurant-quality favorite perfect for lunch or dinner.

Ingredients

• Ground Beef – 1 ⅓ pounds; choose 80/20 for that juicy flavor and texture.
• Kosher Salt – 1 tablespoon + 1 teaspoon; enhances the meat’s natural taste.
• Coarse Black Pepper – 1 tablespoon + 1 teaspoon; adds a touch of spice to each bite.


For the Sautéed Wild Mushrooms
• Extra Virgin Olive Oil – 2 tablespoons; perfect for sautéing and adding richness.
• Diced Shallots – ¼ cup; lends a subtle sweetness, easily swapped with onions.
• Wild Mushrooms – 16 ounces; use a mix like shiitake and oyster for the best umami flavor.
• Fresh Thyme – 1 teaspoon; infuses aromatic notes that elevate the mushroom mixture.

For Assembly
• White Cheddar Cheese – 8 slices; provides melty richness on top of your burger.
• Aioli – ½ cup; creamy goodness that complements the gourmet burger perfectly.
• Brioche Buns – 4; soft and buttery, these buns are ideal for a gourmet experience.

Optional Toppings
• Green Leaf Lettuce – adds a refreshing crunch to each bite.
• Cooked Bacon – brings a smoky flavor, adding indulgence.
• Pickled Red Onions – add a tangy kick and extra texture to your burger.

Directions

Preheat the Grill: Set up your grill for two-zone cooking, heating it to 400°F. If you’re using a cast iron skillet for your mushrooms, make sure it’s preheated on the grill as well.

Season and Shape Patties: In a large bowl, combine the ground beef with kosher salt and coarse black pepper. Gently form the mixture into patties that are slightly larger than your brioche buns. Don’t forget to press a small indentation in the center of each patty; this helps them cook evenly.


Sauté Mushrooms: In that heated cast iron skillet, pour in the extra virgin olive oil. Add the diced shallots and sauté for about 3-5 minutes until they soften. Then, toss in the wild mushrooms, cooking them for around 20 minutes until they become beautifully browned. Season your mixture with thyme, salt, and pepper.

Grill Burgers: Place your seasoned patties on the direct heat of the grill. Grill them for 4-5 minutes on each side. When the internal temperature hits 140°F, lay on the white cheddar cheese slices, cover the grill, and allow the burgers to reach 155°F. Let them rest for 5 minutes after grilling.

Toast the Buns: Simultaneously, throw your brioche buns cut-side down onto the grill. Grill them for about 30 seconds to 1 minute, just until they are lightly browned and toasty.

Assemble the Burger: It’s time for the grand assembly! Spread a generous layer of aioli on the bottom half of each bun. Layer on the crunchy green lettuce, followed by the juicy patty, sautéed wild mushrooms, crispy bacon if desired, and pickled onions if you’re feeling adventurous. Cap it off with the top half of the bun and get ready to indulge!
