In a skillet, melt the butter over medium heat. Add the diced onion and celery and sauté for 6–8 minutes until softened.
Pour the broth into the skillet with the vegetables and warm it through. Stir in garlic powder, pepper, and poultry seasoning.
Add the Pepperidge Farm stuffing mix to a large bowl.
Gradually pour the hot broth mixture over the stuffing, stirring gently until the bread absorbs the liquid.
Adjust the moisture: add less liquid for drier stuffing or up to ½ cup more broth for softer stuffing.
Preheat the oven to 350°F (175°C).
Transfer the stuffing to a greased baking dish.
Cover with foil and bake for 25 minutes. Remove foil and bake an additional 10 minutes until the top is lightly golden.
Fluff with a fork and serve warm.
Notes
Add broth slowly to reach your preferred texture.Use low-sodium broth to avoid overly salty stuffing.Don’t overmix the stuffing — it can become mushy.Mix-ins like sausage, mushrooms, bacon, apples, pecans, or herbs can be folded in before baking.For a slow cooker version, cook on LOW for 3–4 hours.
