Instant Pot Rasam – Warm and Delicious

Rasam is an ancient soup that originates from South India. It is a warm, comforting dish that feels like a hug on any day. Whenever I am craving some comfort, I always go back to making this rasam soup. However, to make it quick, I often make the Instant Pot version of this soup to go with plain boiled rice or just as it is. It is tangy, warm, aromatic, and absolutely delicious. Instant Pot makes things so much easier and quicker, without compromising on taste, and that is what I love about Instant Pot recipes so much. You just need to throw everything in, and it takes care of the rest. So, let us try my go-to Instant Pot rasam recipe together.

Rasam is a tomato- or tamarind-based soup that has been enjoyed in South India for ages. It generally needs a sour ingredient like tamarind or tomato, along with some lentils and spices. The star of this dish, however, is the rasam podi, or rasam masala. Homemade rasam powder can work wonders for the flavor and aroma of the dish, so I generally make my own rasam powder at home and then store it for a few batches. To finish this amazing recipe, you need a tempering (aka – thalipu or tarka), which consists of fragrant Indian herbs and spices and gives this recipe an extra kick of flavor. South Indian Paattis (grandmas) believe that a good rasam can cure almost any ailment. So it is also given as an easy-to-digest comfort food to sick people.
