How do you heat cornbread dressing with drying it out?

To heat cornbread dressing without drying it out, preheat your oven to 350°F (175°C). Place the dressing in an oven-safe dish and add a splash of broth or water to maintain moisture. Cover the dish with aluminum foil to trap steam, and heat for about 20-30 minutes, or until warmed through. Stir halfway to ensure even heating.
