Add the chicken broth, Better Than Bouillon, onion powder, garlic powder, dried thyme, dried sage, rosemary, Worcestershire sauce, pepper, and bay leaf to a saucepan.

Place the saucepan on the stove over medium heat and bring the ingredients to a simmer. Whisk continuously and let it simmer for 5-10 minutes.

Carefully remove the bay leaf from the saucepan. Then, mix the cornstarch with equal parts cold water in a bowl. After that, pour the cornstarch slurry into the saucepan and whisk. Continue to whisk while the gravy simmers for at least 5 minutes or until the gravy thickens and reaches the desired consistency.

Taste the gravy once it has cooled and add a pinch of salt if needed. Then, transfer the gravy to a heat-safe container. Enjoy and store leftovers in an airtight container in the refrigerator.
