There’s something about a smash burger that just hits differently.
The crispy edges, juicy center, and layers of melty cheese…now imagine all of that elevated with the earthy richness of truffle oil. That’s exactly what this Truffle Smash Burger delivers: indulgent comfort food with a gourmet twist.
I remember the first time I tried adding truffle oil to a burger. It completely transformed a weeknight dinner into something restaurant-worthy. The garlic aioli, paired with Havarti and Parmesan, adds just the right amount of tangy creaminess to balance the savory beef and onions. And if you love mushrooms (I do!), the optional sautéed mushrooms are the perfect finishing touch.
This is a burger you’ll want to make when you’re craving comfort but also want to impress. Whether it’s a family dinner, a casual weekend, or when hosting friends who appreciate bold flavors.

🗒 Tips and Tricks
- Use a cast-iron skillet for the best crust and flavor.
- Don’t overwork the beef! It keeps the patties tender.
- Toast your buns for extra texture and to hold up against the aioli.
🗒 Variations
- Swap Havarti for Swiss, Gruyère, or cheddar.
- Use turkey or chicken in place of beef for a lighter version.
- Add caramelized onions instead of raw for a sweeter flavor.
🗒 Substitutions
- Brioche buns → potato buns or whole wheat buns
- Truffle oil → infused olive oil (lighter flavor)
- Havarti → mozzarella, Swiss, or cheddar
🗒 Best Served With
- Crispy fries 🍟
- Sweet potato wedges
- A simple green salad 🥗
- Ice-cold craft beer or sparkling water
👝 How to Store Leftovers
- Store patties and aioli separately in airtight containers.
- Refrigerate for up to 3 days.
- Reheat burgers in a skillet for crispy edges — avoid microwaving to keep texture.

🤔 Common Questions
1. Can I make these burgers ahead of time?
Yes, shape the patties in advance and refrigerate for up to 24 hours before cooking.
2. What’s the best way to get a good smash crust?
Make sure your skillet is very hot and smash the patties immediately when you place them down.
3. Can I grill these instead?
Yes, but you won’t get quite the same crispy edges as with the skillet smash method.

🍔 Truffle Smash Burgers
Ingredients
For the Garlic Aioli:
- ½ cup mayonnaise
- 2 cloves garlic finely minced or grated
- 1 tsp lemon juice
- 1 tsp truffle oil
- Salt & pepper to taste
For the Smash Burgers:
- 1½ lbs ground beef (preferably 80/20 blend)
- Salt & freshly ground black pepper
- 4 slices Havarti cheese
- ¼ cup grated Parmesan cheese
- 1 large white onion thinly sliced into half moons
- 4 brioche or potato buns toasted
Optional Topping:
- Sautéed mushrooms
Instructions
- Make the Garlic Aioli: In a small bowl, whisk together mayonnaise, garlic, lemon juice, truffle oil, and a pinch of salt and pepper. Cover and refrigerate until ready to use.
- Sauté the Mushrooms (Optional): Heat a little oil in a pan over medium heat. Add sliced mushrooms and sauté for 5–7 minutes, until golden brown and tender. Season with salt and pepper, then set aside.
- Prepare the Burger Patties: Divide the ground beef into 4 equal portions and gently roll them into balls. Avoid overworking the meat to keep the burgers juicy. Season with salt and pepper.
- Cook the Smash Burgers: Heat a large cast-iron skillet or griddle over medium-high heat. Add the meatballs to the skillet and immediately top with a handful of thinly sliced onions. Smash the meatballs flat with a heavy spatula or burger press until thin, pressing the onions into the meat. Cook for 1–2 minutes until the edges are crispy and browned.
- Add Cheese: Flip the patty and sprinkle a generous amount of Parmesan on top. After about 1 minute, add a slice of Havarti and cook for an additional minute, until melted and cooked through.
- Assemble the Burgers: Spread garlic aioli on the bottom buns. Place patties on top, add mushrooms if using, and close with the top bun.
- Serve: Serve hot with fries or a side salad. For extra truffle flavor, drizzle a little more truffle oil on top.
