In ‘N Out Inspired Sliders

Heat 1 teaspoon oil in a skillet over medium-high heat. Add onions and 1/2 teaspoon salt to skillet. Reduce heat to medium low, stirring occasionally until onions are well browned. This process takes about 15-20 minutes – be patient, it’s worth the wait! When the onions start to sizzle add about 1 tablespoon water to skillet and stir. Continue cooking until the water evaporates and onions start sizzling again. Repeat this process until your onions are nice and brown. Remove from pan and set aside.

You can make the “spread” while your onions are doing their thing. Combine mayonnaise, ketchup, relish, sugar, and vinegar in small bowl. Stir to combine and set aside.

Form your patties using a 1/4 cup scoop. Flatten to about 1/2″ and then make a thumb print in the middle so they stay flat while cooking. Season generously with salt and pepper. Add remaining 1/2 teaspoon oil to pan, swirl to coat, and heat over medium-high heat until lightly smoking. Add burger patties and cook without moving until well browned and crusty on first side, about 3 1/2 minutes. While patties are cooking, spread 1 teaspoon of yellow mustard on the raw side of each patty with a spoon. Flip patties with a thin spatula so mustard side is down and continue to cook for 1 1/2 minutes. Top each patty with a slice of cheese (1 quarter of an American cheese slice) spoon about a teaspoon of the onion mixture over the cooked patties. Prep each bottom bun with spread (I actually put spread on the top and bottom bun – but do what you like), one pickle slice, 1 slice of tomato, and lettuce. Place the patty on the bottom bun. Top with top bun, and serve immediately!
