Pre-heat the oven to 400 degrees Fahrenheit. Line a baking sheet with parchment paper and set it aside.
Place ¾ cup of the chicken broth in a small saucepan and bring it to a boil. Once boiling, add the stuffing mix and dried cranberries and stir together until combined. Cover the pot and remove from heat. Allow the stuffing to sit covered for five minutes and then uncover and fluff with a fork.
Place the chicken breasts on a cutting board. Using a sharp knife, slice the breasts from the side (creating a top and bottom) almost all the way through. In a small dish, combine the ½ teaspoon salt, ¼ teaspoon pepper, ¼ teaspoon thyme, and ¼ teaspoon garlic powder and stir together. Keeping the chicken breasts folded shut, sprinkle the seasoning over the tops of the breasts and flip over to sprinkle over the bottoms. Flip the breasts back over and open them up.
With each breast open at the slit, divide the stuffing between each open chicken breast, about 1/3 cup each. Spread the stuffing evenly across one side the open chicken. Close the breasts, folding the top half back over the stuffing and press it down.
In a large skillet, add the olive oil and bring over medium-high heat (if your skillet or sauté pan doesn’t fit all four breasts, just cook two breasts at a time with 1 ½ teaspoons of oil each round). Add the stuffed chicken breasts to the pan and cook for about 1 minute until the bottoms are golden. Flip the breasts and cook for another minute on the other side. Transfer the breasts to the prepared baking sheet and stuff any errant stuffing back in if needed. Place in the pre-heated oven. Bake for 18-22 minutes until chicken is fully cooked through.
While the chicken is baking, rinse out the small saucepan you used to make the stuffing and place it back on the stove, Add the two tablespoons of light butter and melt over medium-low heat. Add the flour and whisk to combine into a paste. Whisk the remaining 1 & ¼ cups broth in a little bit at a time, stirring to combine as you go so that the flour mixture dissolves smoothly into the broth. Add the Better Than Bouillon and Gravy Master and whisk into the gravy. Raise the heat to bring it to a boil, stirring regularly, and then reduce the heat to low to simmer. Simmer uncovered for a few minutes until the gravy thickens.
When the chicken is done baking, serve each stuffed chicken breast with about ¼ cup of gravy to pour over the top.
