Infused with familiar Indian spices, chicken tikka masala is rich and tempting. England’s national dish, it is worth every bit of time it takes in the kitchen.
Combine all ingredients for the marinade EXCEPT the chicken in a bowl and mix well. Add the chicken and coat thoroughly.
Cover the bowl and marinate in the fridge for at least 4 hours, but preferably overnight. Since the marinade has lemon juice, don't marinade it longer than 24 hours, or the meat may become mushy.
Curry Sauce (Masala)
Gather all your masala ingredients.
Put a cup of water beside the stove, in case it is needed. In a large dutch oven or saucepan over medium-high heat add ghee, onions, and a big pinch of salt. Cook until the onions have gone from translucent to light golden; this will take about 8 to 10 minutes. Stir frequently. Add a tablespoon or two of water if the onions are sticking to the bottom of the pan.
If using your oven to cook the chicken preheat your grill, or your oven broiler to high with a rack placed 6 inches below the elements, or turn your oven on to 450°F (230°C). Prepare a baking sheet by covering it with aluminum foil.
Back to the sauce: Turn down the heat to medium and add the green chili, if using; cook another minute. Stir in the ginger garlic paste and cook stirring constantly until the paste no longer smells raw. This will take 2 to 3 minutes.
Add the paprika, and cook for 2 minutes. Stir in some water if the spices are sticking to the bottom of the pan. Add the curry sauce spices and salt. Cook a further 2 minutes, stirring frequently.
Stir in the tomato pureé and bring to a simmer. Cover and reduce heat to medium to medium-low. Simmer for 10 minutes, stirring occasionally. You are looking for the sauce to thicken and turn a darker shade of red. When the oil or ghee starts to shimmer on top of the mixture, you know it is ready for the next step.
Meanwhile, start browning the chicken. Even bits of char is good, but there is no need to cook it through completely; it will also be simmered in the sauce. Cooking the chicken can be done on a grill, under a broiler 6 inches away from the elements, in the oven at 450°F (230°C), or in a large frying pan.
If cooking on the stovetop, add 1 tablespoon of oil over medium-high heat and sauté in 2 batches to not crowd the pan. Brown the chicken on both sides. Depending on the size of your chicken pieces, it will take around 8 minutes on the first side and another 6 minutes on the second.
Back to the masala: if using kasoori methi, crush it between your fingers and stir into the sauce. Turn the heat to medium-low and cook for 5 more minutes.
If you want a silky smooth sauce, blend with a stick or regular blender until smooth. (See Note 3) If you used a blender, return the sauce to the pan. Add the cream (The amount of cream you use depends on how intensely flavored you want your curry to be), or ground cashews, sugar, and butter.
Add the chicken. Simmer for another 5 minutes, making sure the chicken is cooked through. Add the yogurt, if using.
If you have time, turn the heat to low, cover, and allow the spices to mix and mingle for 10 minutes. If the sauce is thicker than you like it, add more cream or or water.
Optional: Sprinkle with a pinch of extra garam masala at the end. Important: Taste for final seasonings: salt, sugar, heat, and more garam masala. Serve over rice, sprinkled with coriander/cilantro if desired. Try this homemade naan to go with your masterpiece!
Notes
I strongly advise that you use chicken thighs for chicken tikka masala; they are much less likely to dry out.
Shortcuts: marinate the chicken for 4 hours rather than overnight. You can also skip the browning step on the grill, broiler or stovetop, and cook the chicken in the sauce. AND if you are really short of time, use a rotisserie chicken or even leftover turkey, marinate as written if you have the time, and proceed with the recipe.
If you prefer a smooth, more finished sauce, feel free to blend it before adding the chicken. Since I am inherently lazy, I chop the onions very finely and use tomato puree. Both of these choices make for a smooth enough sauce for my taste.
As usual, add both more fresh chilis and ground chili to your taste. I am often cooking this masala for guests and want to be careful about the heat level.
Certainly, salt to your taste, but I find heavily spiced curries tend to need a healthy amount of salt.
Feel free to swap out the cream for coconut milk, if you need to make a dairy-free chicken tikka masala. And coconut yogurt can be used instead of cow's milk yogurt.
