Preheat the oven to 350 degrees Fahrenheit.

In a small bowl, combine 2 tbsp of ketchup with Worcestershire sauce.

In a small skillet, heat olive oil and sauté minced onion until translucent, about 3 to 5 minutes. Remove from heat.

In a medium bowl, combine ground turkey, sautéed onion, breadcrumbs, egg, 1/4 cup ketchup, salt, and marjoram.

Shape the mixture into a loaf in a baking pan and spoon sauce on top.

Bake uncovered for 55 minutes. Let rest for 5 minutes before slicing.
