My recipe story

This burger was born out of my love for pairing bold flavors with comfort classics. The inspiration came during a trip to a small gastropub where I tasted a burger topped with whiskey caramelized onions. I thought—why not push it further with mushrooms, a silky garlic butter drizzle, and melty Swiss cheese? After a few experiments in my own kitchen, the result was this indulgent yet balanced burger that became an instant favorite. Friends and family always request it at gatherings, and I promise it’ll become one of your most memorable homemade burgers too.

Ingredient breakdown

Every layer of this burger is designed to deliver maximum flavor. The base is high-quality ground beef with a little fat content—ideally 80/20—for juicy smash patties that crisp beautifully on the griddle. A sprinkle of salt and pepper is all that’s needed to let the beef shine.

The star topping is whiskey-glazed mushrooms. Sautéed mushrooms soak up a glaze made from whiskey, brown sugar, butter, and Worcestershire sauce, creating a deep, slightly sweet, and savory profile that complements the beef perfectly. The whiskey burns off, leaving only its smoky warmth.

Swiss cheese is the perfect choice for this burger because of its mild, creamy flavor and the way it melts into silky perfection over the patties. The garlic butter drizzle is made with fresh garlic sautéed in butter and parsley, adding a luxurious finish that makes this burger irresistible. Finally, brioche buns tie everything together with their soft, slightly sweet texture.

Equipment you’ll need

• Cast-iron skillet or griddle (for smash patties)
• Wooden spoon or spatula (for mushrooms and glaze)
• Small saucepan (for garlic butter)
• Burger press or heavy spatula (for smashing patties)
• Sharp knife and cutting board
• Toasting pan or oven broiler (for buns)

Step-by-step directions

1. Prepare the mushrooms: Heat butter in a skillet over medium heat, add mushrooms, and cook until golden and tender. Stir in whiskey, brown sugar, and Worcestershire sauce, letting the mixture simmer until thick and glossy. Set aside while you prepare the burgers.
2. Make the garlic butter drizzle: In a small saucepan, melt butter and sauté minced garlic until fragrant but not burnt. Add parsley and a pinch of salt. Keep warm on very low heat so it’s ready to drizzle at the end.
3. Shape and smash the patties: Roll ground beef into loosely packed balls, about 3–4 ounces each. Heat a cast-iron skillet or griddle until very hot. Place a beef ball on the hot surface and press down firmly with a burger press or spatula to form a thin patty. Season with salt and pepper. Cook until crispy on the edges, then flip.
4. Add the cheese: Place a slice of Swiss cheese over each patty immediately after flipping. Cover the skillet briefly to help the cheese melt completely over the beef.
5. Toast the buns: While patties finish cooking, lightly butter and toast brioche buns until golden brown. This step prevents sogginess and adds flavor.
6. Assemble the burgers: Place the cheesy patty on the bottom bun, spoon over whiskey-glazed mushrooms, and drizzle with warm garlic butter. Add the top bun and serve immediately while hot and melty.

Variations & substitutions

If you prefer a different cheese, provolone or gouda also work beautifully with the whiskey glaze. For a stronger flavor, try aged cheddar. You can swap beef with ground turkey or chicken for a lighter version, though beef delivers the best smash burger texture. Not a whiskey fan? Substitute beef broth with a splash of balsamic vinegar for a tangy glaze. And if you’re looking for vegetarian options, use a thick portobello mushroom cap in place of the patty—it pairs perfectly with the glaze and garlic butter.

Storage, freezing & make-ahead

Cooked patties can be refrigerated in an airtight container for up to 3 days. Reheat in a skillet to restore crisp edges. The whiskey-glazed mushrooms keep well in the fridge for 2–3 days and can be reheated gently on the stove. Garlic butter can be made ahead and stored in a sealed jar for up to 5 days. If you want to freeze the patties, cook and cool them completely before freezing with parchment paper between layers. Reheat straight from frozen in a hot skillet. Assemble fresh for best results.

Serving ideas & pairings

Serve these burgers with a side of crispy fries, onion rings, or sweet potato wedges for the ultimate comfort meal. A light coleslaw or arugula salad can balance the richness. For drinks, pair with a chilled lager, a smoky bourbon cocktail, or even a sparkling water with lemon if you prefer non-alcoholic options. If you want to impress guests, serve the burgers with roasted garlic aioli or a tangy pickled vegetable side for contrast.

FAQ

Can I make the whiskey glaze without alcohol?
Yes, substitute beef or mushroom broth with a splash of balsamic vinegar for a similar depth of flavor.

What’s the best cheese alternative to Swiss?
Provolone, gouda, or Monterey Jack are great choices depending on how strong you want the flavor.

Do I need a burger press for smash burgers?
No, a sturdy spatula or even a small cast-iron pan pressed down firmly works just as well.

Can I make this recipe on an outdoor grill?
Yes, use a cast-iron skillet or flat-top griddle on your grill for the smash technique.

How do I prevent my burgers from getting soggy?
Always toast the buns and assemble just before serving. Avoid overloading with too much glaze or butter.
