Heat oil in a heavy-bottom pan over medium heat. Add cumin seeds and let them splutter.
Next, add minced garlic, green chili, and asafoetida, and saute for a few seconds until fragrant.
You can also add onions and saute until the onions turn light brown at this stage. I did not use onions in this recipe.
Add cubed potatoes, turmeric powder, red chili powder (optional), salt, mix well and stir fry for 2-3 minutes.
Add 2-3 tablespoons of water. Cover, and cook the potatoes for 6 to 7 minutes on medium-low heat until they are fork-tender. You may stir occasionally once or twice in between.
Then add chopped methi leaves and cook for another 5 to 6 minutes uncovered (keep stirring in between), until the leaves wilt, the moisture dries out, and the potatoes are perfectly cooked.
Lastly, add amchur powder (dry mango powder) and garam masala and mix very well. Turn off the heat.
Serve dry Aloo Methi with roti or bread of your choice.
