Red Lentil Soup with Sumac
I used to make this on the stove top all the time, but now I prefer to use the Instant Pot. Whip up a batch whenever you have a few minutes to spare, and it will stay piping hot until you’re ready to enjoy it. The soup is brightly flavored from the squeeze of lemon juice stirred in at the end of cooking. That addition really makes the dish, so don’t skip it! Serve the soup drizzled with extra-virgin olive oil and sprinkled with sumac (a lemony Middle Eastern spice) for a fresh, peppery finishing touch.

Recipe Notes

If you like, add 1 teaspoon of a favorite spice blend to the soup when you add the lentils. Garam masala, ras el hanout, and berbere are three of my favorites.
