- 1½ pounds bulk sausage (removed from casings)
- 9 large eggs
- 10 slices bread, cubed (7.5 ounces or about 6 cups; I use Pepperidge Farm original white bread, not the thin type. GF works, too. See notes)
- 1½ teaspoons dry mustard
- 1½ cups (6 ounces) grated sharp cheddar cheese
- 1 teaspoon kosher salt
- 3 cups (720ml) milk (I use 2% but have used nonfat with good results)
