Step 1

Sprinkle the chicken breasts with 2 teaspoons salt.

Step 2

Heat the oil in a large skillet over high heat; partially cook the chicken in the hot oil in batches until completely browned. Transfer the browned chicken breasts to a plate and set aside.

Step 3

Reduce the heat under the skillet to medium-high; add the onion, garlic, and ginger to the oil remaining in the skillet and cook and stir until the onion turns translucent, about 8 minutes. Stir the curry powder, cumin, turmeric, coriander, cayenne, and 1 tablespoon of water into the onion mixture; allow to heat together for about 1 minute while stirring. Mix the tomatoes, yogurt, 1 tablespoon chopped cilantro, and 1 teaspoon salt into the mixture. Return the chicken breast to the skillet along with any juices on the plate. Pour 1/2 cup water into the mixture; bring to a boil, turning the chicken to coat with the sauce. Sprinkle the garam masala and 1 tablespoon cilantro over the chicken.

Step 4

Cover the skillet and simmer until the chicken breasts are no longer pink in the center and the juices run clear, about 20 minutes. An instant-read thermometer inserted into the center should read at least 165 degrees F (74 degrees C). Sprinkle with lemon juice to serve.
