Creating the Roasted Chicken Stuffed with Bacon and Celery Stuffing is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare the Stuffing: In a skillet, cook the diced bacon over medium heat until crispy. Remove the bacon and drain on paper towels.
3. Sauté Vegetables: In the same skillet, add chopped celery and onion. Sauté until soft, about 5 minutes.
4. Combine Ingredients: In a large bowl, combine bread cubes, cooked bacon, sautéed celery and onion, chicken broth, thyme, sage, salt, pepper, and parsley. Mix well.
5. Stuff the Chicken: Pat the chicken dry with paper towels. Fill the cavity with the stuffing mixture, pressing gently to pack it in. Tie the legs together with kitchen twine.
6. Season the Chicken: Rub the outside of the chicken with olive oil, garlic powder, onion powder, salt, and pepper.
7. Roast the Chicken: Place the stuffed chicken in a roasting pan. Roast in the preheated oven for about 1 hour and 15 minutes or until the internal temperature reaches 165°F (75°C).
8. Rest the Chicken: Remove the chicken from the oven and let it rest for 10-15 minutes before carving. This allows the juices to redistribute.
9. Serve: Carve the chicken and serve with the stuffing on the side or spooned from the cavity.
