"This is a simple, simple chicken casserole, like a chicken pot pie, kinda, but with a couple of twists, and we're going to top it with Old Bay biscuits!" says Rach. The flavor base of the dish is a combination of bell pepper, celery and onion, a staple in southern cooking, especially Cajun-Creole, that's nicknamed the trinity, she explains. Be sure to sweat it long enough for the veg to soften; the onions also get sweeter and the pepper mellows out. After that, everything comes together really quickly, especially since Rach uses a rotisserie chicken and store-bought tube biscuits.
