Lamb Biryani Casserole
6 servings
This recipe uses long-grain brown rice to make a biryani-style casserole, with sweet flavors to match the earthy whole grain and lots of spices for big pops of flavor. Those spices are whole and will soften under pressure. You might not find many spice bits because of the way the pressure acts on them. But warn anyone who won’t appreciate a sudden mouthful to pick out any whole spices found on their plate.
2 tablespoons vegetable, corn, or canola oil
2 medium yellow onions, halved and sliced into thin half-moons
2 teaspoons coriander seeds
1 teaspoon cumin seeds
1 teaspoon table salt
½ teaspoon ground dried turmeric
½ teaspoon ground black pepper
8 green or white cardamom pods, lightly crushed
8 whole cloves
One 4-inch cinnamon stick
1 bay leaf
1½ cups raw long-grain brown rice
2 pounds boneless leg of lamb, any large bits of fat removed, the meat cut into 1-inch pieces
2½ cups beef or chicken broth
