Ingredients & Their Role

For the Patties & Onions

• 1 tbsp olive oil: Helps onions start caramelizing evenly and prevents scorching.
• 2 cups finely chopped onions: Cooked down to golden, sweet richness that balances the savory beef.
• 6 tbsp unsalted butter (divided): Adds deep flavor, aids browning, and gives buns a buttery crunch.
• 2 tbsp ketchup: Adds tangy sweetness and moisture to the beef, enhancing umami.
• 1½ lbs lean ground beef: The star of the burger—provides natural tenderness, rich flavor, and a meaty texture.
• 2 tsp Worcestershire sauce: Infuses savory depth and classic burger-shop umami flavor.
• ½ tsp onion powder: Supplements fresh onions with gentle aromatics for balanced flavor.
• 1 tsp kosher salt + fresh cracked pepper: Essential for amplifying beef flavor and seasoning the patties evenly.
• 4 sandwich buns: Soft, slightly sweet, and sturdy enough to hold the juicy patties without falling apart.

For the Secret Sauce

• ½ cup mayonnaise: Creamy base that binds flavors together.
• 2 tbsp ketchup: Adds sweetness and a tangy undertone.
• 1 tbsp Dijon mustard: Provides mild heat and depth.
• 1 tsp garlic powder: Enhances savory notes.
• 1 tsp smoked paprika: Adds subtle smokiness for complexity.
• 1 tsp pickle juice: Brightens flavors and balances richness.
• Salt & pepper to taste: Fine-tunes the overall flavor balance.

Step-by-Step Instructions

Step 1: Caramelize the Onions (20–25 minutes)

Heat olive oil in a large skillet over medium heat. Add the finely chopped onions and stir often to prevent burning. Cook slowly until deep golden brown and sweet, about 20–25 minutes. Season lightly with salt and pepper during cooking. Once caramelized, transfer the onions to a bowl and keep warm.

Step 2: Prepare the Secret Sauce (5 minutes)

In a small bowl, combine mayonnaise, ketchup, Dijon mustard, garlic powder, smoked paprika, and pickle juice. Mix until smooth. Adjust salt and pepper to taste. Cover and refrigerate until ready to assemble the burgers.

Step 3: Season the Beef (2 minutes)

In a large mixing bowl, gently combine the ground beef with ketchup, Worcestershire sauce, onion powder, kosher salt, and cracked pepper. Do not overmix, as this will make the patties dense instead of tender.

Step 4: Portion & Pre-Chill (10–15 minutes)

Divide the beef mixture into 4 equal balls. Flatten slightly to a diameter just larger than your buns. Chill in the refrigerator for 10–15 minutes to help the patties hold their shape during smashing.

Step 5: Preheat the Pan & Sear (8–10 minutes)

Heat a heavy cast-iron skillet or griddle over medium-high heat. Add 2 tbsp butter and let it melt completely. Place the beef balls on the hot skillet and smash firmly with a spatula or burger press until thin. Cook 4–5 minutes per side until edges are lacy, crisp, and deeply browned. Avoid moving the patty too soon to allow the crust to develop.

Step 6: Toast the Buns

While the patties cook, melt remaining butter and lightly toast the sandwich buns in a separate pan or on the skillet until golden and slightly crispy. This ensures buns are flavorful and sturdy enough for juicy patties.

Step 7: Assemble the Burgers

Spread a generous layer of secret sauce on both the top and bottom buns. Place the smashed patty on the bottom bun, add a heaping spoonful of caramelized onions, and top with the bun crown. Optional: add cheese, lettuce, tomato, or pickles as desired.

Pro Tips for Perfect Smash Burgers

• Use high heat: Essential for achieving a crispy, lacy crust.
• Do not over-smash: Flatten enough for crispness but not so thin that the patty dries out.
• Chill the patties: Keeps shape during smashing and prevents shrinkage.
• Butter the buns: Adds flavor and keeps them from becoming soggy from the patty juices.
• Cook in batches: Avoid overcrowding to maintain high heat and perfect searing.
• Experiment with seasoning: Add smoked paprika, chili powder, or fresh herbs to elevate flavors.

Serving Suggestions

• Pair with crispy fries, sweet potato fries, or onion rings.
• Serve with pickles, coleslaw, or a fresh side salad.
• Offer extra secret sauce on the side for dipping.
• Serve with a cold beverage like soda, beer, or iced tea to complement the rich flavors.
• For a gourmet touch, add avocado slices, bacon, or a fried egg on top.

Storage and Reheating

• Refrigeration: Store cooked patties, onions, and sauce separately in airtight containers for up to 3 days.
• Freezing: Wrap patties individually and freeze for up to 1 month. Thaw in the refrigerator before reheating in a skillet or oven.
• Reheat gently to maintain crispiness—avoid microwaving directly, which may make the crust soggy.

Creative Variations

• Cheeseburger Smash: Add cheddar, American, or Swiss cheese during the last minute of cooking for melty goodness.
• Spicy Smash: Add sriracha, jalapeños, or hot sauce to the secret sauce.
• Bacon Lovers: Add extra crispy bacon slices on top of the caramelized onions.
• Vegetarian Version: Use smashed black bean patties with caramelized onions and the same secret sauce for a satisfying alternative.
• Gourmet Toppings: Arugula, roasted mushrooms, or truffle aioli elevate this burger for special occasions.

Frequently Asked Questions (FAQ)
