Ingredients

2 cups shredded Colby and Monterey Jack cheese blend
6 large eggs
½ cup milk
Salt and black pepper, to taste
1 (2.75 oz) packet country sausage gravy mix
2 cups water or milk (milk for a creamier texture)

Instructions

Preheat the oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish.
Prepare the biscuits:
Cut each biscuit into 8 pieces and spread them evenly across the bottom of the baking dish.
Add the sausage layer:
Sprinkle the cooked and crumbled sausage evenly over the biscuit pieces.
Add the cheese:
Evenly distribute the shredded cheese over the sausage layer.
Prepare the egg mixture:
In a medium bowl, whisk the eggs and milk together for about 2 minutes until well combined. Season with a pinch of salt and pepper.
Pour the mixture evenly over the cheese layer without stirring.
Prepare the gravy:
In another bowl, whisk together the gravy mix and water (or milk) until smooth.
Pour the gravy evenly over the egg layer, again without stirring.
Bake:
Cover the dish with foil and bake on the center rack for 45–55 minutes, or until the biscuits are fully cooked.
Finish baking:
If the biscuits are still soft in the center, remove the foil and continue baking for a few more minutes until they are cooked through.
Serve:
Let the casserole rest for a few minutes before slicing. Serve warm with extra gravy if desired.
