Ingredients You’ll Need
Here’s everything required to bring this flavor-packed burger to life:
- 1 lb ground beef – 80/20 is ideal for juicy burgers.
- Salt and pepper – the simplest yet most important seasonings.
- 4 slices Swiss cheese – melty, nutty perfection.
- 1 cup sliced mushrooms – baby bella or cremini work beautifully.
- 1/4 cup whiskey – bourbon or rye adds depth.
- 2 tbsp brown sugar – caramel sweetness for the glaze.
- 2 cloves garlic, minced – fragrant and savory.
- 2 tbsp butter – for the garlic drizzle.
- 4 hamburger buns – brioche or potato rolls elevate the experience.
Step-by-Step Instructions
1. Shape and Season the Patties
Divide the ground beef into four equal portions. Gently shape into balls (not flat patties yet—save that for the smash!). Season both sides generously with salt and pepper.
2. Smash and Sear
Heat a cast-iron skillet or griddle over medium-high heat until smoking hot. Place a beef ball in the skillet, then press down firmly with a spatula or burger press to flatten. Let it sear undisturbed for 2–3 minutes until crispy and browned. Flip, top with Swiss cheese, and cook another 1–2 minutes until melted. Repeat for all patties.
3. Sauté the Mushrooms
In the same skillet, toss in the mushrooms. Let them cook until golden brown, releasing their juices and soaking up any leftover beef flavor from the pan.
4. Make the Whiskey Glaze
In a small saucepan, combine whiskey, brown sugar, and minced garlic. Simmer over medium heat until the sugar dissolves and the mixture reduces slightly into a glossy glaze.
5. Add the Butter
Remove from heat and stir in butter until silky smooth. This transforms the glaze into a sauce that doubles as your garlic butter drizzle.
6. Assemble the Burgers
Place a cheesy smash patty on the bottom bun. Top with a generous spoonful of mushrooms, then drizzle with whiskey garlic butter. Crown with the top bun.
7. Serve and Enjoy
Serve hot with fries, onion rings, or even a side salad. Don’t forget extra whiskey glaze on the side for dipping.
Pro Tips for the Best Smash Burger
- Don’t overwork the beef – lightly shape it to keep the texture tender.
- Use high heat – a screaming hot skillet ensures that crispy crust.
- Freshly shredded Swiss – it melts better than pre-sliced.
- Let the glaze thicken – patience pays off; a reduced sauce clings better to mushrooms and burgers.
- Toast the buns – lightly buttered and toasted buns keep everything sturdy and flavorful.
Variations to Try
Want to make this recipe your own? Here are some tasty variations:

- Spicy Kick – mix a little sriracha or chipotle into the whiskey glaze.
- Caramelized Onion Upgrade – swap mushrooms for slow-cooked onions or use both.
- Double Smash – stack two cheesy patties for a towering masterpiece.
- Whiskey BBQ Style – stir in a tablespoon of barbecue sauce with the whiskey glaze for a Southern twist.
What to Serve with Your Whiskey-Glazed Smash Burger
A burger this bold deserves sides that complement without overpowering. Try pairing it with:
- Crispy Shoestring Fries – thin and golden, perfect for dipping in extra glaze.
- Sweet Potato Wedges – earthy and slightly sweet to balance the whiskey notes.
- Onion Rings – crunchy and indulgent.
- Coleslaw – creamy and tangy for a refreshing contrast.
- Pickles – add a sharp bite that cuts through the richness.
Beverage Pairings
Because this burger is infused with whiskey, it pairs beautifully with drinks that complement those flavors:
- Classic Whiskey Sour – tangy, citrusy, and smooth.
- Iced Sweet Tea – balances the richness with refreshing sweetness.
- Craft Beer – IPAs or stouts work especially well.
- Sparkling Water with Lime – keeps the meal lighter and refreshing.
Storing and Reheating
If you happen to have leftovers (though that’s unlikely with this recipe!), here’s how to store them:
- Refrigerate: Store patties, mushrooms, and glaze separately in airtight containers for up to 3 days.
- Reheat: Warm patties in a skillet over medium heat. Reheat mushrooms and glaze gently on the stovetop.
- Avoid microwaving buns – toast fresh ones instead for the best texture.
Make-Ahead Tips
- Glaze in advance – the whiskey glaze can be made a day ahead and reheated before serving.
- Pre-sliced mushrooms – save prep time with store-bought sliced mushrooms.
- Batch patties – form and season them ahead, then refrigerate until ready to cook.
Frequently Asked Questions
Can I use a different cheese?
Yes! Provolone, Gruyère, or even cheddar would work well, but Swiss balances the whiskey glaze best.
What’s the best whiskey to use?
A good-quality bourbon or rye whiskey adds depth without being overpowering. Avoid overly peaty whiskeys like some Scotch varieties.
Can I make this without alcohol?
Absolutely. Replace the whiskey with beef broth and a splash of apple cider vinegar for tang.
Can I grill the patties instead?
Yes, but you won’t get the same “smash” crust. A flat-top griddle on the grill can mimic the skillet effect.
Is this recipe kid-friendly?
The alcohol cooks off during the glaze-making process, leaving behind flavor but no alcohol content. Still, if you prefer, use the non-alcoholic substitution.
