Prepare the Instant Pot: Set your Instant Pot to “Sauté” mode and heat 2 tablespoons of vegetable oil.
Sauté Spices: Once the oil is hot, add the chopped onion, 2 bay leaves, a pinch of cinnamon powder, garam masala seasoning, and 1 teaspoon of cumin powder. Sauté until the onion softens.
Add Aromatics: Stir in 1 teaspoon of ginger-garlic paste and sauté until it turns golden brown.
Add Spices: Mix in ½ teaspoon of turmeric, ¾ teaspoon of chili powder, ½ teaspoon of coriander powder, and ¾ teaspoon of salt. Sauté for a minute until the spices are fragrant.
Add Lauki and Tomatoes: Add the chopped tomatoes and 450 grams of diced lauki (Chinese long squash). Sauté for 2-3 minutes.
Pressure Cook: Add 1 cup of water or canned diced tomatoes and mix well. Cancel the “Sauté” mode, close the lid, and set the Instant Pot to “Pressure Cook” or “Manual” mode on high pressure for 5 minutes.
Natural Release: Once the cooking time is up, allow the pressure to release naturally for 10 minutes, then do a quick release for any remaining pressure.
Garnish and Serve: Open the lid, stir in chopped coriander, and adjust the consistency if needed by adding more water. Serve the Lauki Sabzi with chapati or rice.
