Creating Gordon Ramsay’s Chicken Tikka Masala can be achieved seamlessly by following these steps:

1. Marinate the Chicken: In a large bowl, combine yogurt, lemon juice, garam masala, cumin, paprika, turmeric, and chili powder. Add the chicken pieces and coat well. Cover and marinate for at least 1 hour in the refrigerator.

2. Cook the Chicken: Heat oil in a large pan over medium heat. Add the marinated chicken and cook for about 5-7 minutes until the chicken is browned. Remove from the pan and set aside.

3. Sauté the Onions: In the same pan, add a bit more oil if needed. Add the chopped onions and cook until soft and golden, about 5-6 minutes.

4. Add Garlic and Ginger: Stir in minced garlic and ginger, cooking for another minute until fragrant.

5. Incorporate Tomatoes: Pour in the crushed tomatoes and stir well. Cook the mixture for about 10 minutes until it thickens.

6. Add Coconut Milk: Stir in the coconut milk or cream and simmer for 5-10 minutes until the sauce thickens further. Season with salt to taste.

7. Combine Chicken and Sauce: Add the cooked chicken back into the sauce, stirring well to combine. Let it simmer for another 5 minutes until the chicken is fully cooked through.

8. Adjust Seasoning: Taste and adjust seasoning if necessary, adding more spices or salt as desired.

9. Garnish: Finish with freshly chopped coriander on top for a touch of color and flavor.

10. Serve: Serve the Chicken Tikka Masala hot with steamed basmati rice or warm naan bread.
