Peel the potatoes and cut them into ¼-inch thick batons. Soak the potatoes in water until ready to use.
Heat oil in a pan over medium-high heat.
Once the oil is hot, add fenugreek seeds and dried red chilies and fry for 3-4 seconds.
Add chopped garlic and fry for 6-8 seconds.
Add potatoes and mix well.
Add turmeric powder, salt, and black pepper powder and mix well.
Reduce the heat to low.
Cover the pan and cook until the potatoes are cooked (5-6 minutes), stirring a few times.
Once the potatoes are cooked, remove the lid and increase the heat to high. Cook for 2-3 minutes until the potatoes are slightly browned. Do not stir too much at this stage. We need the potatoes to have a nice browning. Serve hot.
