Ingredients marked with * can be measured and mixed at home.
Prepare coals for baking at 350 F degrees (25 coals total = 17 top/8 bottom) if using a standard-depth 12-inch Dutch oven. NOTE: Depending on your cooking conditions, you may need two batches of coals to complete the cooking of this recipe.
Season chicken on all sides, sprinkle with the mixed spices: chili powder, ground cumin, dried oregano, coriander, salt and pepper.
Place Dutch oven over medium-high heat (using all coals below the oven) to sear the chicken. Add 1 tablespoon olive oil to pot and let it get hot, then place the chicken in the bottom of the pot.
Let the chicken form a crispy texture with a golden-brown color, about 5 minutes. Then, flip the chicken to brown the second side, about 5 more minutes.
Remove browned chicken to a plate and set aside.
Continue with a medium-high heat and add the remaining 1 tablespoon olive oil and the onions to the pot.
When the onions are softened, stir in the garlic.
As soon as the garlic is fragrant, stir in the uncooked rice, salsa and chicken broth. Cover and bring the mixture up to a boil then return the chicken to the pot.
Cover with tight-fitting lid and place coals under the oven (8 below) and on top of the lid (17 on top) to bake at 350 F degrees until the chicken reaches an internal temperature of 165 degrees F, about 40-50 minutes. Rotate the oven and lid in opposite directions every 15 minutes for even baking.
Serve chicken over rice and top with cilantro, if desired.
