1. Place the saffron in a cup with 2-3 ice cubes, set aside. Wash the rice 2-3 times and let it soak until needed. Wash and drain the lentils. Cook the lentils in a small pot until just tender. You don’t want it to be mushy, mine took 20 minutes. Once cooked, drain and set aside. Save the lentil water for soups!
2. Meanwhile, cut the onion in half and then slice it lengthwise, as you would for caramelized onions. Heat up 2-3 tbsp of oil in a skillet and toss in the onions. Sprinkle some salt to help them release their moisture. Saute on medium heat until golden, around 5 minutes. Once golden, add the seasoning, and saute until fragrant, around 30 seconds. Turn off the heat and toss in the drained lentils. Give them a good mix and set aside.
3. Fill a medium-sized pot (preferably non-stick) with water and bring it to a boil. Once boiling, add a tsp of salt and toss in the rice. Cook until al dente, around 6 minutes. Drain immediately and rinse the rice with water. Meanwhile, wash, peel, and cut your potato widthwise into ¼ inch disks, set aside.
Add enough oil to cover the bottom of the non-stick pot off the heat. Add 2-3 tsp of the brewed saffron and twirl it around the pot. Arrange the potato disks in the pot until the bottom is covered. For this process, if you don’t have a non-stick pot and worry that the potatoes might stick, line the bottom of the pot with parchment paper.
4. Now spoon in 2-3 heap tbsp of the lentil mixture, and spread it around. Follow up with 2-3 heap tbsp of rice and repeat this layering process until there are no remaining lentils or rice. You should finish with the rice on top. Use the bottom of a spoon to puncture 5-6 holes in the mixture. This helps the rice steam evenly. Drizzle any excess saffron extract on top. Cover the lid with a clean cloth and place it on top. Now place the pot on medium-high heat for 3 minutes and then lower the heat. Let the rice steam for 25 minutes. This should be done on a small burner so the bottom doesn’t burn.
5. As the rice is steaming, we can make our topping. Pit the dates and cut them into quarters. Heat up 1-2 tbsp of butter or oil in a small pan. Once the butter is melted, toss in the dates and let them fry in the butter until toasted, around 2 minutes.
6. After 25 minutes, turn off the heat and let the pot rest for 1 minute before taking off the lid. Take the lid off and run a knife around the edges of the rice to separate the crispy rice from the pot. Place a large plate (preferably with edges) on top of the pot, and carefully flip it over.
Now all that’s left to do is enjoy that crunchy potato tahdig, the fluffy aromatic rice, the caramelized buttery dates, and my favorite part, the crunchy lentils sticking to the potatoes.
