Preheat your oven to 375°F.

Place the potatoes in a large bowl and set aside.

In a heavy skillet over medium heat, sauté the onion and garlic in olive oil until tender, about 5 minutes. Add the parsley and oregano.

Add to the potatoes along with the eggs, bread crumbs, 1/3 cup of the ketchup, salt and pepper and mix well until thoroughly combined. Add ground beef and mix gently just until combined.

Place in a casserole pan and shape the mixture into an 8 x 4-inch loaf. Spread the remaining 1/3 cup ketchup over top of the loaf.

Bake at 375°F for 70-75 minutes or until the center is no longer pink and an instant-read thermometer reads 160°F when inserted in the center of the loaf.

Let stand, covered, 15 minutes before slicing.
