Sourdough breakfast strata combines tangy homemade sourdough bread, sausage, and herbs baked in a custard mixture, topped with cheese.
I recommend using whole milk for the best texture. I use goat milk (from our own goats) or milk from another local farm.
Bake in a large cast iron skillet or 9×13 baking dish.
Make this ahead of time by starting it the night before. Allow it to soak, covered, in the refrigerator for 8-12 hours.
