Equipment
- Cast-iron skillet
- Flat-top griddle (optional)
- Sturdy Spatula
- small saucepan
Ingredients
For the Burgers
- 1 lb Ground Beef 80/20 Blend
- Salt and Pepper to taste
- 4 slices Swiss Cheese
- 1 cup Sliced Mushrooms Baby Bella or Cremini
- 4 Hamburger Buns Brioche or Potato Rolls
For the Whiskey Garlic Butter Glaze
- 1/4 cup Whiskey Bourbon or Rye
- 2 tbsp Brown Sugar
- 2 cloves Garlic minced
- 2 tbsp Butter
Instructions
- Step 1: Prep Your Patties: Divide the ground beef into four equal, loose balls. Season generously all over with salt and freshly cracked black pepper. Do not overwork the meat, as this can make your burgers tough.
- Step 2: Heat a cast-iron skillet or flat-top griddle over medium-high heat until it gets seriously hot, almost smoking. This is crucial for a fantastic smash burger crust.
- Step 3: Smash and Sear: Carefully place one beef ball onto the screaming hot skillet. Immediately use a sturdy spatula to press down firmly and flatten the beef ball into a thin patty. Let it sear for 2-3 minutes without disturbing it, until gorgeous, crispy, browned edges form.
- Step 4: Flip and Cheese: Carefully flip the patty. Immediately top it with a slice of Swiss cheese. Let it cook for another 1-2 minutes, just until the cheese is perfectly melted and gooey. Remove the cheesy patty from the skillet and set it aside. Repeat this process for the remaining beef balls and cheese slices.
- Step 5: Sauté the Shrooms: In the same hot skillet, toss in your sliced mushrooms. Sauté them over medium heat, stirring occasionally, until they’re beautifully golden brown and tender (about 3-5 minutes). Once done, remove them from the skillet and set them aside.
- Step 6: Whip Up the Whiskey Glaze: In a small saucepan, combine your whiskey, brown sugar, and minced garlic. Place it over medium heat and bring to a gentle simmer. Stir occasionally, letting the sugar dissolve completely and the mixture reduce and thicken into a glossy, syrupy glaze (about 5-7 minutes). Remove from heat and stir in the 2 tbsp butter until completely melted and incorporated.
- Step 7: Assemble Your Masterpiece: Lightly toast your hamburger buns, ideally in the same skillet for extra flavor and texture. Place a cheesy smash patty on the bottom half of a bun, pile a generous amount of sautéed mushrooms on top, and drizzle liberally with your whiskey garlic butter glaze. Place the top bun on.
- Step 8: Serve Immediately: These burgers are best enjoyed right away, while everything is warm, melty, and the flavors are at their peak.
Notes
Tips for Success: Get your skillet screaming hot to achieve a crispy, lacy crust. Gently form beef balls without overworking the meat. Smash patties firmly and quickly, then leave them undisturbed to sear. Toasting buns adds flavor and prevents sogginess. Watch the whiskey glaze carefully to prevent burning; adjust consistency with a tiny splash more whiskey/water if too thick, or simmer longer if too thin. You can prep patties, slice mushrooms, and make the glaze ahead of time.
Substitutions & Additions: Try provolone, white cheddar, Muenster, or Gruyere cheese. Experiment with pretzel or classic sesame seed buns. For leaner, use ground chicken/turkey. For a whiskey-free glaze, substitute with balsamic vinegar or rich beef broth, reducing with brown sugar and garlic. Add crispy fried onions, bacon, caramelized onions, or a fried egg. A pinch of red pepper flakes in the glaze or a dash of hot sauce can add a lovely kick.
How to Store: Store cooked patties and sautéed mushrooms separately in airtight containers in the refrigerator for up to 3-4 days. The whiskey garlic butter glaze can be stored in an airtight container in the fridge for up to a week; gently reheat before serving. Assemble burgers just before serving to prevent soggy buns.
