Prepare the Rice. Add the vegetable broth, apple juice, Dijon mustard, 1 tablespoon of the butter, salt, pepper, parsley, oregano, thyme, garlic powder, and bay leaf to a large, wide saucepot set over high heat. Cover and bring to a boil. Once boiling, immediately reduce heat to a simmer. Uncover and add the rice, mixing well to combine. Cover with a tight-fitting lid.
Cook and check the rice. After approximately 20-25 minutes, begin checking the rice at regular 5-minute intervals for doneness. The liquid will be mostly absorbed, but this may also vary greatly depending on the type of rice used. To check if your rice is done, try a few grains or smash a few grains between your thumb and index finger. The rice should not be mushy- some firmness is good. Once the rice has finished cooking, strain the rice through a fine-mesh strainer and (optional) set the broth aside in a separate bowl.
Cook the vegetables. Heat a large heavy-bottomed pan or skillet over medium heat. Add the remaining tablespoon of butter and onion to the skillet. Cook the onion for 5-6 minutes, stirring often. Add the celery and carrots and continue to cook for 3-4 minutes before adding the sweet potatoes. Sprinkle with a pinch of salt and sauté for 8-10 minutes, stirring frequently. Do not brown or burn the vegetables. Add the apples and garlic and continue to cook for an additional 5-6 minutes, or until apples are tender. Finally, add the dried cranberries.
Return the Rice. Reduce heat to medium-low and add the drained rice back to the pan with the softened vegetables. Mix in the apple cider vinegar and pecans. Mix to combine.
Garnish and Serve. Remove rice from heat and add additional seasoning, as needed. Garnish with fresh thyme and rosemary, if desired.
