The best way to prevent dry stuffing is to be careful not to overcook it! You want the dressing top to be crispy and golden brown, with a soft and tender interior. It's important to keep an eye on your dish as it bakes to make sure the top is not getting overly browned. If you feel like the top is brown before the inside is done, simply cover the dish with foil. In a situation where the stuffing bakes for too long and is dry, mix 2 tablespoons of melted butter with 1/3 cup warm chicken or turkey broth. Drizzle this mixture over the stuffing and let it soak in for a few minutes, and that should help to fix the problem.
