1-First, prepare all ingredients by chopping the onion, mincing the garlic and ginger, and dicing the chicken into bite-sized pieces. This step sets you up for success and keeps things organized in the kitchen.

2-Next, heat 2 tablespoons of olive oil in a large pan over medium heat. Add the chopped onion and sauté until it softens, which takes about 5 minutes, to build a flavorful base.

3-Then, stir in the minced garlic and ginger, cooking for 1-2 minutes until their aroma fills the air. This adds a fresh punch to the dish.

4-Now, add the spices like coriander, cumin, turmeric, fennel seeds, cinnamon, pepper, ground mustard, ground cloves, and cayenne pepper. Toast them for about 1 minute to release their full flavor.

5-Add the diced chicken breasts and stir to coat them with the spices. Cook for 5-7 minutes until the chicken starts to brown, locking in those rich tastes.

6-Pour in the chicken broth and diced tomatoes, then stir everything together and bring to a simmer. Let it cook covered on low heat for 15-20 minutes so the flavors meld.

7-If you want a thicker sauce, mix in the cornstarch slurry and stir well. Finally, add the heavy cream and let it warm through for a creamy finish.

8-Garnish with chopped cilantro and serve hot. For tips on variations, see our mastering section below.
