Preparing the Ingredients: Begin by peeling and chopping the potatoes into small cubes. Dice the tomatoes and chop the onion, ginger, and garlic. This step will take around 10-12 minutes.

Heating the Oil: In a pan or Kadai, heat about 2 tablespoons of oil on medium heat. Once the oil is hot, add cumin seeds and allow them to sizzle for a few seconds. This step will take about 2 minutes.

Sautéing the Onions: Add the chopped onions to the pan and sauté until they become golden brown. Stir occasionally to prevent burning. This will take about 4-5 minutes.

Adding Ginger and Garlic: Now, add the grated ginger and minced garlic to the pan. Sauté them together with the onions for another 1-2 minutes until fragrant.

Cooking the Tomatoes: Add the chopped tomatoes to the pan and cook them until they soften and turn slightly mushy. Stir occasionally. This will take around 5 minutes.

Spicing it Up: Add turmeric powder, red chili powder, coriander powder, and salt to the mixture. Stir well to combine all the spices. Let it cook for another 2-3 minutes so the spices release their flavor.

Adding the Potatoes: Now, add the diced potatoes to the pan and stir them with the tomato-spice mixture. Cook for 2 minutes to coat the potatoes in the flavors.

Simmering the Dish: Add water to the pan, enough to cover the potatoes. Stir everything, cover, and let it cook on low to medium heat for about 15-20 minutes, or until the potatoes are soft and cooked through. Check occasionally and add more water if needed to maintain the desired consistency.

Final Touch: Once the potatoes are cooked, sprinkle garam masala and mix well. Let it simmer for another 2 minutes. Your Aloo Tamatar Ki Sabzi is now ready!
