Place the breadcrumbs in the bowl and gently mix with milk or bone broth to saturate. Add up to 1/2 cup of milk or bone broth.
Once the breadcrumbs are saturated, add egg, garlic, onion, salt and pepper, 1/4 cup of ketchup, parsley, and thyme to the bowl and mix well.
Add meat to the breadcrumb mixture and mix gently with an open hand until all ingredients are incorporated. Do not over mix and do not squeeze the meat through your fingers.
Free-form meat mixture into a loaf on a foil-lined baking sheet or use a loaf pan to shape the meat mixture. (See the recipe video.)
Mix the remaining 1/4 cup of ketchup and the Worcestershire sauce together, and brush over the top and sides of the meatloaf.
Place meatloaf into a preheated 350°F oven and bake until the internal temperature reaches 160°F. Approximately 1 to 1 1/2 hours.
