If I’m not making homemade, I use Costco boxes of chicken broth (certified gf) or Savory Choice packets. My co-op has them but so does Amazon. Not cheap but good for adding a bit of flavor to a dish. We also use them for instant ramen (Savory Choice Chicken Broth Concentrate, 5.1 Ounce box https://www.amazon.com/dp/B002HQUZIM/ref=cm_sw_r_cp_api_i_NN4ZCbFNKEPF9)
