Creating Chicken Tikka Masala at home is straightforward when you follow these steps:

1. Marinate Chicken: In a mixing bowl, combine yogurt, lemon juice, garam masala, cumin, coriander, turmeric, chili powder, and salt. Add the chicken cubes, ensuring they are fully coated. Cover and refrigerate for 30 minutes or overnight for enhanced flavor.

2. Heat Oil: In a large pan or skillet over medium heat, add vegetable oil. Once hot, introduce the finely chopped onion and sauté until golden brown (about 5-6 minutes).

3. Add Aromatics: Stir in minced garlic and ginger, cooking for an additional 1-2 minutes until fragrant.

4. Cook Chicken: Remove the marinated chicken from the refrigerator and add it to the pan. Cook for about 5-7 minutes, stirring occasionally, until the chicken is no longer pink.

5. Incorporate Tomatoes: Pour in the crushed tomatoes and stir well to combine. Cook for 5 minutes.

6. Add Cream: Reduce the heat to low, then pour in the heavy cream. Stir to create a creamy sauce, letting it simmer for an additional 5-10 minutes. Add salt to taste.

7. Garnish: Once done, remove from heat and garnish with fresh cilantro before serving.

8. Serving Options: You can serve Chicken Tikka Masala hot with naan bread, basmati rice, or your choice of sides.
