Can I use leftover gravy instead of making a roux?
Yes. Whisk in 1 to 1 1/2 cups leftover gravy after the veggies soften, then add broth as needed to reach a thick, spoonable consistency. Still bake with biscuits on top as usual.
What if my filling is too thick?
Add broth (or a splash of milk) a little at a time until it loosens. It should look like a thick stew. Remember it will thicken more as it bakes.
What if my filling is too thin?
Simmer it uncovered for a few minutes before topping with biscuits. If it is still thin, mash a tablespoon of softened butter with a tablespoon of flour, whisk it in, and simmer 2 to 3 minutes.
Can I use rotisserie chicken instead of turkey?
Absolutely. Same amounts, same method. It becomes a weeknight chicken pot pie situation, and nobody complains.
Do I need a cast iron skillet?
Nope. Any oven-safe skillet works. If you do not have one, make the filling in a regular pan and transfer to a baking dish before adding biscuits.
How do I keep biscuits from getting soggy underneath?
Make sure the filling is hot and bubbling before the biscuits go on, and leave a little space between biscuits so steam can escape. Also, bake on the upper-middle rack if your oven runs cool.
Do I bake canned biscuits the same as homemade?
Not always. Canned biscuits can brown fast at high heat. If you are using refrigerated canned biscuits, you can bake at 400°F (or follow the package temperature) and simply add time as needed until the centers are cooked through.
