Step 1

Preheat the oven to 400°. Combine the milk and panko breadcrumbs in a small bowl. Set aside for 15 minutes.

Step 2

Heat a large skillet over medium heat. Add the olive oil, then the onion and cook, stirring occasionally, until slightly softened, about 4 minutes. Add the garlic and mushrooms. Cook for another 3 to 4 minutes, stirring occasionally, until most of the moisture from the mushrooms has evaporated. Transfer to a large plate and let cool slightly.

Step 3

Place the ground turkey, parmesan, Worcestershire sauce, seasoned salt, black pepper, parsley, and onion mixture in a large mixing bowl. Pour in the eggs and panko mixture.

Step 4

With clean hands, mix the ingredients until evenly combined. (Do not overmix!)

Step 5

Line a baking sheet with aluminum foil and spray with nonstick spray. Form the mixture into a loaf shape, about 6 inches wide, in the center of the pan.

Step 6

For the sauce: Combine the ketchup, brown sugar, mustard, and Worcestershire sauce in a mixing bowl. Stir together. Pour one third of the mixture over the top of the meatloaf. Spread with a brush or back of a spoon.

Step 7

Bake for 10 minutes, then reduce heat to 350° and bake for another 20 minutes. Pour another one third of the sauce over the top. Bake for another 20 minutes or until the internal temperature of the meatloaf is 165° in the center. Slice and serve with the remaining sauce.

Step 8

Serve with mashed potatoes and green beans, if you like.
