Prepare the ingredients: Peel the potatoes and cut them into one-inch cubes. Dice the onions into small cubes and mince the garlic cloves.
Sauté: Preheat a pot over medium-low heat, then drizzle with cooking oil and add the onion and garlic. Gently mix the ingredients and cook for about three to four minutes while stirring occasionally.
Add the potatoes, water, and spices: Add the potatoes to the pot and half a cup of water. Then, add turmeric powder and paprika powder, and gently toss from bottom to top to coat the potatoes with the blend of spices.
Cook the potatoes: Add the tomato paste and stir until well combined. Cover the pot with a lid and simmer for 25-30 minutes over medium-low heat. Check the water level every ten minutes, and also check if the potatoes are cooked. Add a quarter cup of water each time, if necessary. Add the dried fenugreek leaves in the last five minutes of cooking.
Garnish and serve immediately: Garnish with a pinch of dried fenugreek leaves on the aloo methi and serve while it is hot and fragrant.
