Follow these easy steps to create Gordon Ramsay Chicken Tikka Masala:

1. Marinate the Chicken: In a bowl, combine the yogurt, lemon juice, garam masala, cumin, coriander, turmeric, chili powder, and salt. Add the chicken pieces and mix well. Cover and refrigerate for at least 30 minutes, allowing the flavors to meld.

2. Cook the Chicken: Heat 1 tablespoon of vegetable oil in a large skillet over medium-high heat. Once hot, add the marinated chicken. Cook until the chicken is browned and cooked through (about 7-10 minutes). Remove and set aside.

3. Prepare the Sauce: In the same skillet, add the remaining oil and sauté the chopped onion until soften and lightly golden (about 5 minutes). Add the minced garlic and grated ginger; cook for an additional minute until fragrant.

4. Add Tomatoes: Pour in the crushed tomatoes and simmer for 5 minutes. Stir occasionally to prevent burning.

5. Incorporate Cream: Lower the heat and gradually stir in the heavy cream. Allow the sauce to simmer gently for about 10 minutes until thickened.

6. Combine Chicken and Sauce: Return the cooked chicken to the skillet. Mix well, allowing the chicken to absorb the rich flavors for about 5 more minutes.

7. Adjust Seasoning: Taste and adjust seasoning if necessary, adding more salt or spice to your preference.

8. Garnish: Once done, garnish with fresh cilantro leaves for a vibrant finish.
