A moist, flavorful turkey meatloaf enhanced with grated apple for juiciness and topped with a sweet and tangy ketchup-brown sugar glaze that caramelizes beautifully during baking. Ideal for a quick weeknight dinner with simple pantry ingredients.
Use an instant-read thermometer to check doneness at 160°F for safety and juiciness., Avoid overmixing to maintain a lighter texture., Keep the apple juice in the grated apple for moisture; do not drain., Add extra moisture like a tablespoon of olive oil, milk, or an extra egg yolk if using extra-lean turkey (less than 90%)., Lining the sheet pan with parchment and spraying with cooking spray eases cleanup and prevents sticking., For firmer slices, let the meatloaf rest the full 10 minutes before cutting., Flavor variations include swapping proteins, adding fresh herbs (thyme, sage, parsley), adding cheese, or changing the glaze., Meatloaf can be made ahead, refrigerated, frozen, and reheated per instructions for convenience.
