Start by heating a little oil or butter in your skillet over medium heat. Toss in the diced onions and cook them for about 2–3 minutes until they turn translucent. Add the minced garlic and stir for another minute until fragrant. This combo sets the flavor base.
Next, add your shredded chicken and frozen vegetables to the skillet. Stir everything together before pouring in the chicken broth and heavy cream. Sprinkle in the thyme, salt, and pepper. Let it simmer for about 5–7 minutes until the mixture thickens slightly.
In a bowl, follow the Cheddar Bay Biscuit mix instructions. Mix in the shredded cheddar cheese and stir until a dough forms. I always recommend grating cheese fresh—pre-shredded just doesn’t melt the same way!
Grease your baking dish lightly. Pour the creamy chicken mixture into the dish and spread it evenly. Using a spoon, drop biscuit dough mounds on top of the filling, spacing them evenly. The biscuits will expand while baking.
Preheat your oven to 400°F (200°C). Bake your pot pie uncovered for 25–30 minutes, or until the biscuits are golden brown and the filling is bubbling up. Let it cool slightly before serving—it’ll be piping hot!
