While not a southern girl, that does not mean I cannot appreciate southern style food, I have spiced this up a bit (not much, you know I am a spice wimp) with some mild and delicious green chiles.

We now have access to recipes from every region, cuisine and tradition, which enhances our taste buds, like these other Southern favorites; Chicken & Sausage Jambalaya, Slow Cooker Red Beans and Rice and Kentucky Butter Cake.

  • SALT | Gotta have a little salt, I use kosher salt
  • CHOPPED GREEN CHILES | I used organic mild chopped green chiles, certainly feel free to add more than 4 oz.

Frequently Asked Questions

Can I make Biscuits and Gravy Casserole ahead of time?

Yes, assemble the entire casserole ahead of time, even refrigerating overnight. Simply bring to room temp (about 30-40 minutes on counter) before baking.

Why does my sausage gravy taste like flour?

A common problem and one easily fixed, you did not “cook” your flour mixture (called a roux) long enough, between 2-3 minutes is enough to cook out the flour taste.

Why is my sausage gravy so thick?

Gravy thickens as it cools, if it has cooled and is too thick, simply thin while heating over low heat with a little extra milk.

If your sausage gravy does not thicken, it might mean you didn’t add enough flour, or you did not cook it long enough, try adding a touch more flour or even a teaspoon of corn starch (mixed with a teaspoon of water) and see if that thickens it up.

Can I freeze Overnight biscuits and gravy casserole?

If baked: Cool completely, cover well with plastic wrap and foil, freezes up to 3 months. Thaw in fridge overnight and bake at 350 degrees for 20 minutes, covered (remove plastic wrap).
Unbaked: Cover well with plastic wrap and foil and freeze up to 2 months, thaw in fridge overnight and bake as directed, removing from fridge 20-30 minutes prior to baking.
Sausage Gravy: Thaw overnight in fridge, reheat in skillet or small saucepan, thinning with a little milk if needed.

Tips

  • PREP AHEAD | recipes always come together easier if you pre-measure your ingredients, chop, etc.
  • CHILES or NO CHILES | If you are not a green chile fan, omit the chiles alltogether. Or if you are big fan, add extra green chiles, up to 8 oz.
  • DON’T EAT PORK?  Make Kosher Biscuits & Gravy Casserole, use chicken breakfast sausage.
