Key Ingredients
Ingredients, directions and nutritional information in the printable recipe card at the end of the post.

Sausage Gravy with Green Chile
- BREAKFAST SAUSAGE | Pork or Chicken your choice! I used an all natural pork breakfast sausage (no fillers, corn syrup or other ingredients)
- BUTTER | not as much as you would think, but this is what makes the roux to thicken and flavor to the gravy.
- FLOUR | Gluten free flour may be used here, for Gluten Free sausage gravy
- WHOLE MILK | I use organic whole milk in all of my cooking and baking, you can certainly try using lower fat %, but it’s a gravy, so why?
- 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 or omit them altogether.
Egg bake ingredients

- EGGS | I always use large eggs in my baking and cooking, I like using organic when I am able.
- WHOLE MILK | just a touch to add to the fluffy creaminess of the biscuits and gravy casserole.
- KOSHER SALT | Yup, a bit more!
- CANNED BUTTERMILK BISCUITS | Yes I use canned biscuits, I like Annie’s, Immaculate or Trader Joe’s brand organic and all natural canned biscuits. But you could make your own if you wanted to show me up, try Julia’s biscuits.
- WHITE SHARP CHEDDAR CHEESE | Pre-shredded or shredded off the block, I used organic shredded white cheddar cheese.
How to make the best breakfast casserole
Let’s make this amazing biscuits and gravy egg bake, first we’ll make the amazing green chile sausage gravy.
Step 1
- Brown the sausage | In a large skillet (I love my cast iron skillets) brown the breakfast sausage until just browned and remove from pan, drain any excess fat (I used lean sausage, so left the little bit of fat behind for flavor)

- Make the Gravy | In the same skillet, melt the butter over medium-low heat, slowly whisk in flour until thickened, just a couple of minutes. Whisk in milk, a little at a time, it will thicken as you whisk it, keep whisking until smooth. Add diced green chiles, salt and return the sausage to the gravy, stirring to combine.


MY FAVORITE PAN =>> Staub 3.5 qt Braiser with Glass Lid
Step 2 | Assemble Egg Casserole
If making the morning of, preheat oven to 350 degrees F and generously spray a 9×13 inch casserole dish with spray oil.
- In a small mixing bowl whisk eggs, milk and salt together.
- Cut the biscuits into quarters and place the biscuit pieces over the bottom of the pan.

- Pour egg mixture over the top of the biscuits.
- Sprinkle with cheese and place a few blobs of sausage gravy around the casserole, be sure to save most for serving. Bake 30-35 minutes until golden and eggs are set.


Step 3
- Serve warm with a spoonful of the delicious green chile sausage gravy. Grab a napkin, drool will happen!

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