Oklahoma Onion Burger

Ingredients

For the Burger Patties:

• 1 lb (450 g) ground beef (80/20 fat ratio recommended)
• 1 teaspoon salt
• ½ teaspoon black pepper

For the Onions:

• 2 large yellow onions (thinly sliced)
• 1 teaspoon salt
• 1 tablespoon butter (optional for richness)

For Assembly:

• 4 burger buns (soft brioche or classic white buns)
• 4 slices American cheese (optional but traditional)
• Pickles (optional)
• Mustard or ketchup (optional)
• Butter for toasting buns

Instructions

Step 1: Prepare the Onions (Intensity: Low to Medium Effort)

1. Peel and slice the onions as thinly as possible. Thin slicing is essential for proper caramelization and integration into the beef.
2. Sprinkle lightly with salt and let them rest for 5 minutes. This helps draw out moisture and enhances flavor.

Step 2: Preheat the Cooking Surface (Intensity: High Heat)

1. Heat a cast iron skillet or flat griddle over high heat. The surface should be very hot to achieve proper searing and caramelization.
2. Lightly butter the surface if desired for extra richness.

Step 3: Form the Beef Balls (Intensity: Low Effort)

1. Divide ground beef into 4 equal portions. Roll each portion into a loose ball—do not flatten them yet. Overhandling the meat should be avoided to keep burgers tender.

Step 4: Cook the Onions (Intensity: Medium Heat)

1. Place a generous handful of sliced onions onto the hot skillet for each burger. Let them begin to sizzle and soften slightly for 1–2 minutes.
2. The onions should start to release aroma but not fully brown yet.

Step 5: Smash the Burger Patties (Intensity: High Heat Action)

1. Place each beef ball directly on top of the onions. Using a sturdy spatula or burger press, firmly smash the beef down so it flattens and presses the onions into the meat.
2. This is the signature step of the Oklahoma Onion Burger. The high heat and pressure allow onions to caramelize directly into the beef.

Step 6: Season and Cook (Intensity: High Heat → Medium)

1. Season the flattened patties with salt and pepper. Cook for about 3–4 minutes on the first side.
2. As the meat cooks, the onions will caramelize and become crispy at the edges while blending into the beef.

Step 7: Flip and Finish Cooking (Intensity: Medium Heat)

1. Carefully flip each burger using a spatula. If the patties are thin, this step requires precision.
2. Cook for another 2–3 minutes until the beef is fully cooked and slightly crispy on the edges. If using cheese, place a slice on top during the last minute to melt.

Step 8: Toast the Buns (Intensity: Medium Heat)

1. Lightly butter the burger buns and toast them on the skillet for 1–2 minutes until golden brown. This adds texture and prevents sogginess.

Step 9: Assemble the Burgers (Intensity: Low Effort)

1. Place the onion-infused beef patty onto the bottom bun. Add pickles, mustard, or ketchup if desired. Top with the bun lid.
2. Serve immediately while hot and juicy.
