It usually takes 30 - 40 minutes to make dry aloo gobi sabji. You sear the potatoes and cauliflower florets in oil and spices, then steam them in their own juices with a little water until they are soft. Aloo gobi masala recipe, on the other hand, takes more time to prepare because you have to deep fry the vegetables first and then simmer them in a gravy made of onions, ginger, garlic and tomatoes.
