Heat the oven to 400 degrees F and arrange a rack in the upper third. Line a baking sheet with foil and set aside.
Add the oil to a medium pan over medium heat. When the oil shimmers, add the onion, garlic and thyme and cook until softened, about 3 minutes; set aside.
In a large bowl, add the eggs, buttermilk
, mustard, Worcestershire, salt, and pepper. Whisk
until the eggs
are broken up and evenly combined. Add the onion mixture, ground pork
, sausage, cracker crumbs, and parsley. Mix until thoroughly combined (don't squeeze mixture).
Dampen your hands, and put the meat on the prepared baking sheet. Form the meat into a 9 by 5- inch loaf. Arrange the bacon across the top of the loaf and bake until the internal temperature is 155 degrees F, on an instant-read thermometer, about 55 to 65 minutes. Remove from the oven to a cutting board and let cool for 10 to 15 minutes before slicing and serving.
