Classic Cheeseburger Box Lunch Recipe

Form patty

Divide the 8 oz ground beef into a single ball and gently form into a patty about 4.5–5 inches in diameter and roughly 3/4 inch thick at the center. Do not overwork the meat. Make a shallow dimple in the center with your thumb to reduce bulging while cooking.

Season

Season both sides of the patty evenly with 1/2 tsp kosher salt and 1/4 tsp freshly ground black pepper just before cooking.

Cook

Heat a griddle or heavy skillet over medium-high heat until hot. Add 1 tsp vegetable oil and swirl. Place the patty on the hot surface and cook undisturbed for 3–4 minutes until a brown crust forms. Flip and cook another 3 minutes for medium doneness (adjust ±1 minute for preferred doneness). During the last 30–45 seconds of cooking, place 1 slice of American cheese on the patty and cover the pan briefly to melt.

Toast buns

While the patty rests (1–2 minutes), split the sesame bun and lightly butter the cut sides with 1/2 tsp softened butter if using. Toast the cut sides on the griddle or in a skillet over medium heat for ~30–45 seconds until golden and lightly crisp.

Assemble burger

On the bottom bun, layer the iceberg lettuce leaf, then the cheese-topped patty. Top with 2 slices of tomato and 3 dill pickle slices. Spread 1 tsp ketchup on the top bun and 1 tsp yellow mustard (and 1 tsp mayonnaise if desired) on the inside of the top bun, then place it on the burger.

Wrap for box

Place the assembled burger on a parchment square and loosely wrap to keep it warm and prevent moisture buildup. Let rest in the wrap for 1–2 minutes before packing.

Place the wrapped burger into the box lunch container or clamshell with the seam side down. Add the single-serve Zapp's potato chips beside the burger. Tuck any extra condiments or napkins in the box. Close the container and label with contents if required.

Serve immediately for best quality. Estimated holding time in an insulated delivery bag is 20–30 minutes; include a small ice pack for extended transport if needed.
