Preheat the oven to 400 degrees F. Season both sides of chicken breasts with seasonings. Begin to heat olive oil in your Dutch oven on stovetop over medium/high heat. Cook and brown outsides for 2-3 minutes on each side.
Once the chicken is browned on the outsides. Remove Dutch oven from heat. Add potatoes, carrots, onion, broth, and fresh rosemary sprigs if you want fresh herbs.
Make sure the potatoes are as submerged into the broth as much as possible, so that they can soften faster. Bake with the lid on for approximately 30 minutes, or until chicken is cooked through and potatoes are tender.
