Wash the Rice and Dal: In a bowl, mix 1 cup of rice and 2.5 tablespoons of moong dal. Wash them 2 to 3 times with clean water and set them aside.
Prepare the Base: Heat 1 ladle of ghee in a pressure cooker over a medium flame. Add 1 teaspoon of mustard seeds and let them splutter.
Add Aromatics: Add 1 teaspoon of cumin seeds, 1 pinch of asafoetida, and curry leaves. Add 1 chopped onion and sauté until it turns light pink (you can skip the onion if you prefer).
Sauté Masalas: Add the crushed ginger, garlic, and green chilli paste. Sauté well. Then, add 1 teaspoon of turmeric powder and 1 chopped tomato. Cook for 1 minute.
Add Spices and Spinach: Stir in 1 teaspoon of cumin-coriander powder and 1 teaspoon of garam masala. Add 1 large bowl of chopped spinach and cook until the leaves shrink and wilt.
Add Spinach Puree: Pour in the pureed spinach paste (made from 10 to 12 spinach leaves). Mix well, and add salt to taste along with chopped coriander leaves.
Add Rice and Water: Add the washed rice and dal mixture into the cooker. Pour 4 to 5 cups of water depending on how soupy you want your easy palak khichdi recipe to be.
Cook the Khichdi: Mix everything well and let the water come to a boil. Close the cooker lid, turn the gas flame to low, and cook for 3 to 4 whistles.
Serve: Let the pressure release naturally. Open the cooker, give it a good stir, and serve hot!
