Preheat an outdoor grill for medium heat and lightly oil the grate.
Combine beef, onion, chile pepper, cilantro, yogurt, flour, cumin, garam masala, turmeric, coriander, garlic, salt, and pepper in a large bowl and mix well with clean hands.
Roll beef mixture in to 4 large balls and flatten into patties 1/2- to 3/4-inch thick. Place on a plate, separated by wax paper, until grill is ready.
Grill burgers until cooked to preference, 5 to 7 minutes per side.
