Smash Burgers Ingredients
For the Burgers
• Ground Chuck – 2 pounds for optimal flavor and juiciness; use an 80/20 mix for best results.
• White Onions – 2, thinly sliced; using a mandoline ensures uniform thickness and enhances flavor.
• Bacon – ½ pound, crispy and chopped; adds smokiness and crunch that elevates the taste of smash burgers.
• Salt, Pepper, Garlic – For seasoning; these ingredients enhance the overall flavor of the meat.
• Mustard – A key cooking element that adds tanginess and aids in browning.
• Pepper Jack Cheese – Sliced, for a flavorful melt that brings extra zing.
• Burger Buns – Toasted for a firm and warm base to hold your delicious topping.
• Avocado Oil – Preferred for cooking due to its high smoke point; perfect for frying.
For the Baconnaise Sauce
• Mayonnaise – ½ cup for creaminess that balances the other flavors nicely.
• Ketchup – 2 tablespoons, adds sweetness and tang to the sauce.
• Mustard – 2 tablespoons, adding additional flavor depth to the baconnaise.

• Worcestershire Sauce – 1 tablespoon enhances umami, bringing a savory richness.

Step‑by‑Step Instructions for Smash Burgers with Baconnaise Sauce
Step 1: Prep the Ingredients
Start by forming the ground chuck into eight 1/3 pound balls and place them on a plate in the refrigerator for 30 minutes to chill. While the beef firms up, thinly slice the onions with a mandoline for even thickness, then squeeze out excess moisture and refrigerate. Finally, cook and chop the bacon until crispy, laying the groundwork for layer upon layer of flavor in your smash burgers.
Step 2: Make the Baconnaise Sauce
In a mixing bowl, combine the mayonnaise, ketchup, mustard, crispy chopped bacon, Worcestershire sauce, apple cider vinegar, all-purpose rub, and red pepper flakes. Stir well until all ingredients are fully blended into a creamy, smoky sauce. Next, cover the bowl and chill in the refrigerator, allowing the flavors of the baconnaise to meld together while you prepare the burgers.
Step 3: Cook the Burgers
Heat a griddle or cast-iron skillet to medium-high heat and coat it lightly with avocado oil. Once hot, space the chilled burger balls evenly across the griddle. Using a heavy spatula or burger press, smash each ball down firmly until it’s about ¼ inch thick. Season the exposed side with salt and pepper, then cook for approximately 3-4 minutes until the edges are beautifully caramelized.
Step 4: Flip & Add Cheese
Once the burgers have developed a nice crust, spread a thin layer of mustard on top of each patty. Carefully flip the burgers over and immediately add a slice of pepper jack cheese to each. Cook for an additional 3 minutes until the cheese melts and the burgers are cooked through, ensuring those savory flavors amp up your smash burger experience.
Step 5: Toast the Buns
While the burgers finish cooking, place the burger buns cut-side down on the griddle. Toast them until golden brown, which should take about 2-3 minutes. This extra step creates a sturdy base for your smash burgers, preventing sogginess and enhancing the overall texture of the final dish.
Step 6: Assemble the Smash Burgers
Begin assembling your smash burgers by spreading a generous layer of baconnaise sauce on the bottom bun. Stack two smash burgers on top of the sauce, then add another dollop of baconnaise before placing the top bun on. This creates a deliciously rich flavor combination that makes every bite of your smash burger an indulgent delight.

How do I choose ripe onions for my smash burgers?
When selecting onions, look for those that are firm with a smooth, dry skin. Avoid onions with dark spots or soft areas, as these are signs of spoilage. Fresh onions are an essential ingredient in maximizing the flavor of your burgers, offering that perfect balance to the savory meat!

Consider using vegan mayonnaise for a dairy-free version or leaving out the bacon altogether for a vegetarian option. Always check ingredient labels if cooking for guests with specific dietary restrictions!
