Step 1

Preheat your oven to 350ºF.

Step 2

Heat the oil in a skillet over medium heat. Add the onion and sauté until golden, 6 to 10 minutes. Add the garlic and sauté for 1 to 2 minutes (be careful not to burn the garlic).

Step 3

Remove the vegetables from the heat and let cool.

Step 4

In a bowl, stir together the meat, eggs, onion and garlic mixture, bread crumbs, mustard, oregano, salt, and pepper until combined.

Step 5

Form a loaf and place it in an 8x4-inch baking dish or loaf pan (preferably glass) or shape it into a 7x5-inch loaf and place it in a roasting pan.

Step 6

Spread the ketchup evenly over the top of the loaf.

Step 7

Bake for 1 hour, or until the meatloaf reaches an internal temperature of 145ºF for beef or 160ºF for turkey. It may take an additional 15 minutes or so if using ground turkey.

Step 8

Remove and allow to rest slightly, draining any excess fat or liquid if necessary.

Step 9

Cut the meatloaf into ½-inch thick slices and serve.

Step 10

Refrigerate any leftovers for up to 2 days.
