Heat oil in a 4- to 6-qt. pot over medium-high heat. Add onion and cook, stirring often, until softened, 3 to 5 minutes. Stir in freekeh, dukkah, and salt.
Add the broth and bring to a simmer. Reduce heat to low, cover, and cook until liquid is absorbed and the grains are tender, 25 to 35 minutes (if using farro, drain off excess broth and save it for soup, if you like). Remove from heat and let steam, covered, 10 minutes; then stir in lemon juice, parsley, and salt to taste.
*Find both freekeh and dukkah, an Egyptian spice blend, at well-stocked grocery stores, Middle Eastern markets, and online. To make your own dukkah, blend 1/4 tsp. each sesame seeds, ground coriander and cumin, dried thyme, and finely chopped roasted hazelnuts.
