Prepare ingredients: Peel and dice the onion. Wash and dice chili. Wash mushrooms and cut them into slices. Rinse cilantro leaves under cold water, separate the leaves from stems. Rinse cutting board then cut the chicken breast into cubes.
Mix chicken, 1/2 cup of yogurt, 3 tbsp of the Garam Masala Spice Mix and lemon juice in a bowl. Cover and let the mixture rest in the fridge for a few minutes.
If you have time, refrigerate for about 30 mins for a more intense flavor.
Heat up 1 ⅓ cups of water in a pot. Once boiling, add rice, cover and reduce the heat to low. Cook rice for about 12 to 15 minutes, or until the rice is tender and completely has absorbed the water. Set the rice aside and fluff it with a fork.
Meanwhile, heat up vegetable oil in a pan. Add chicken-yogurt mix and onion cubes. Cook for about 10 minutes at medium to high heat until chicken is fully cooked and turns golden brown.
Add tomato puree, the second half cup of yogurt and the sliced mushrooms to the cooked chicken and mix the ingredients. If you would like to make it creamy, you can add 1/2 cup of milk or cream to the sauce. Let masala sauce simmer for another 5 to 10 minutes at low heat. Add more Garam Masala Mix or salt to taste.
Serve rice on two flat plates and top with chicken tikka masala sauce. Garnish with cilantro leaves. If you want to make it spicier, you can add some chopped chilies.
