Step-by-Step Instructions to Create the Perfect Smash Burger

Now, let’s break down how to assemble this burger step by step. Don’t worry; even though it might sound fancy, making this Truffle-Swiss Caramelized Onion Smash Burger is simple and straightforward!

Step 1: Prepare the Beef Patties

Start by preheating a skillet or griddle over medium-high heat. While the pan is heating up, take your ground beef and place it in a mixing bowl. Add the truffle oil, salt, and black pepper, and gently mix the ingredients together with your hands. You want the seasonings evenly distributed throughout the meat, but be careful not to overwork it.

Now, divide the seasoned beef mixture into four equal portions and form them into balls. Don’t worry about shaping them perfectly—they’re going to get smashed into perfect patties anyway!

Step 2: Smash and Sear the Patties

Once the skillet is hot, place the beef balls in the pan. Here’s where the magic happens: Take a spatula or a heavy object (like another pan) and smash each beef ball down to form a thin patty. You want to press hard, so the edges get crispy and caramelized while the center stays juicy. Let the patties cook for 3-4 minutes per side (depending on your desired doneness), making sure to flip them carefully.

After flipping, immediately place a slice of Swiss cheese on each patty and cover the skillet to help the cheese melt. This will only take about a minute, so keep an eye on it!

Step 3: Caramelize the Onions

While your patties are cooking, it’s time to work on the onions. In a separate skillet, melt butter over medium heat. Add the sliced onions and stir them occasionally, allowing them to soften and slowly caramelize. This process should take about 10-15 minutes, and the onions should turn a deep golden brown. The longer you let them cook, the sweeter and richer they’ll become!

Step 4: Make the Garlic Aioli Swirl

While the onions are caramelizing and the patties are cooking, you can prepare the garlic aioli. In a small bowl, mix together the mayonnaise, minced garlic, and lemon juice. Add salt and pepper to taste. Give it a good stir, and set it aside. You’ll want this creamy, garlicky goodness ready to spread on your burger buns.

Step 5: Toast the Buns

As everything is coming together, it’s time to toast your hamburger buns. Place the buns cut-side down in a hot pan or under the broiler for a minute or two, until they’re golden brown. This step gives the buns a crispy texture that contrasts beautifully with the juicy patty and rich aioli.

Step 6: Assemble the Burger

It’s finally time to build your Truffle-Swiss Caramelized Onion Smash Burger! Spread a generous amount of the garlic aioli on the bottom bun. Next, place your cheesy patty on top, followed by a hearty serving of the caramelized onions. Finally, add the top bun, and you’re ready to dig in!

Tips for the Perfect Burger Every Time

• Use Fresh Ingredients: When making burgers, fresh ingredients make all the difference. Fresh ground beef, crisp buns, and freshly minced garlic will enhance the overall flavor.
• Smash the Patties Properly: Don’t be afraid to really press down on the patties. The smash technique is what creates that crispy, flavorful crust.
• Low and Slow for the Onions: Caramelizing onions takes patience. Low heat and slow cooking help release their natural sugars, creating that perfect sweet flavor.
• Garlic Aioli is Key: Don’t skimp on the garlic aioli—it’s the creamy, tangy finishing touch that ties everything together!
