Preheat oven to 375 °F (190 °C). Line a loaf pan (8×4-inch) or baking sheet with parchment paper.

In a small bowl, soak breadcrumbs in milk until absorbed, about 2 minutes.

In a large bowl, combine ground turkey, soaked breadcrumbs, chopped onion, garlic, egg, ketchup, Worcestershire sauce, parsley, thyme, salt, and pepper. Mix until just combined—do not overwork.

Shape into a loaf and place in prepared pan.

In another bowl, stir together ketchup, brown sugar, and mustard. Spread glaze evenly over the top of the loaf.

Bake for 45–50 minutes, until internal temperature reads 165 °F (74 °C) at the center.

Let meatloaf rest 10 minutes before slicing to allow juices to redistribute.

Slice and serve warm—great with mashed potatoes, steamed veggies, or a green salad.
