Ingredients

12 ounces ground beef two 6-ounce portions
Salt
2 slices aged cheddar
2 thick onion slices
2 brioche buns
2 tablespoons burger sauce
Butter or oil for toasting buns

Instructions

Shape: Form two 6-ounce patties from 12 ounces ground beef, handling lightly.
Season: Sprinkle salt over both sides just before cooking.
Sear: Cook patties over medium-high heat for 3 to 4 minutes per side, adding 1 slice cheddar to each burger after flipping.
Char Onion: Grill or sear 2 thick onion slices until softened and caramelized.
Toast: Lightly butter and toast 2 brioche buns.
Assemble: Spread 1 tablespoon burger sauce on each bun, add the patty, top with onion, and close.

Notes

Try not to overwork the beef. Loose shaping keeps it tender.
If your onion slice is too thin, it won’t hold up. Go thicker than you think.
Let the burger rest a minute before stacking. It keeps the bun from getting soggy.
This Blueprint works for backyard grilling just as well as cast iron indoors.
