Step-by-Step Instructions

Step 1: Prepare the Special Sauce

Combine mayonnaise, ketchup, pickle relish, garlic powder, and smoked paprika in a small bowl. Stir until completely mixed and set aside to allow flavors to meld while you prepare the burgers. Pro tip: Make this a day ahead for even better flavor development.

Step 2: Prepare the Meat

Divide the ground beef into 4 equal portions (about 4 ounces each) and gently form into loose balls. Don’t compact the meat – keeping it loose ensures a better smash and more crispy edges. Season each ball generously with salt and pepper on all sides.

Step 3: Prepare the Onions

Heat a cast iron skillet over medium-high heat. Add a teaspoon of oil and the finely diced onions. Cook for 2-3 minutes until they just begin to soften but aren’t fully caramelized. You want them to retain some moisture for the smashing process. Remove from heat and let cool for 2 minutes.

Step 4: Smash and Cook the Burgers

Heat your skillet or griddle to high heat (around 450°F). Add remaining oil to the surface. Place the meat balls on the hot surface and immediately place a small handful of the prepared onions on top of each ball. Using a sturdy spatula or burger press, firmly smash each patty to about ¼-inch thickness. The thinner, the better for developing those crispy edges that make a Ultimate Crispy Onion Smash Burger (Better Than Fast-Food!) so irresistible.

Step 5: Perfect the Flip

Cook undisturbed for 1-2 minutes until the edges are deeply browned and lacy. Using a sharp-edged spatula, scrape underneath to release all the crispy bits and flip in one decisive motion. Immediately add cheese to each patty and cook for an additional 30-45 seconds.

Step 6: Prepare the Buns

While the burgers cook, lightly butter the insides of each bun and toast them on a separate section of the griddle or in a toaster until golden brown. This creates a protective barrier against soggy buns – a common mistake in burger preparation.

Step 7: Assemble the Burger

Spread special sauce on both bun halves. Place the cheesy patty on the bottom bun and add any additional toppings of your choice. Cover with the top bun and serve immediately for maximum enjoyment of the contrasting textures.

Common Mistakes to Avoid

1. Over-handling the meat: Working the beef too much creates dense, tough burgers. Statistics show that overworked beef can reduce juiciness by up to 40%.
2. Skipping the high heat: Temperature data indicates that a minimum of 400°F is required for proper Maillard reaction.
3. Smashing after cooking begins: The magic happens when you smash immediately upon contact with the hot surface.
4. Using the wrong fat ratio: Testing shows 80/20 beef provides the ideal balance of flavor and juiciness.
5. Not letting the pan get hot enough: Preheat your cooking surface for at least 5 minutes to ensure optimal crust development.

Storing Tips for the Recipe

• Cooked patties can be refrigerated for up to 2 days; reheat in a hot skillet rather than microwave to preserve texture.
• Pre-portion raw meat balls and freeze individually for up to 3 months – you can cook directly from frozen by adding 1 minute to the cook time.
• Special sauce keeps in the refrigerator for up to 5 days in an airtight container.
• For meal prep, prepare onions in advance and store refrigerated for up to 3 days.

FAQs

Can I make these burgers on a grill instead of a skillet?
While traditional grills don’t provide the flat surface needed for proper smashing, you can use a cast iron plate or griddle on top of your grill grates to achieve similar results.

Why is 80/20 ground beef recommended?
This ratio provides enough fat to create flavor and juiciness while still allowing for those crispy edges. Leaner meat tends to become dry, while fattier blends can cause excessive flare-ups.

Can I make these ahead for a party?
It’s best to cook these right before serving, but you can prepare the meat balls, onions, and special sauce in advance to streamline the process.

How do I know when my cooking surface is hot enough?
When a few drops of water dance and evaporate immediately upon contact with the surface, you’re ready to cook.

What’s the best tool for smashing the burgers?
A sturdy metal spatula works well, but a dedicated burger press or even the bottom of a small cast iron pan can provide even better results by distributing pressure evenly.
