Preheat your oven to 350 degrees and lightly grease a 9x13-inch casserole dish.
Unroll one tube of crescent rolls and press it into the bottom of the dish, sealing the seams together. Bake for 15 minutes until just set.
In a large bowl, mix together the shredded chicken, thawed vegetables, hash browns, chicken broth, cream of chicken soup, and seasonings until combined.
Pour the chicken mixture over the baked crescent layer and spread it out evenly. Unroll the second tube of crescent rolls and place it on top, pinching the seams together as best you can. Cut a few small slits in the top.
Bake for another 20-25 minutes, until the top is golden. Let it sit for about 5 minutes before slicing and serving.
