Preheat your oven to 350°F (175°C) and lightly grease a loaf pan.
In a large mixing bowl, combine the ground beef and ground turkey. Mix them together using your hands or a spoon until they are well combined.
Add the breadcrumbs, chopped onion, minced garlic, beaten eggs, milk, ketchup, Worcestershire sauce, oregano, thyme, salt, and pepper to the meat mixture. Mix gently until all ingredients are well incorporated.
Fold in the grated Parmesan cheese and diced bell pepper, ensuring even distribution.
Transfer the meat mixture into the prepared loaf pan, smoothing the top with a spatula.
Spread a thin layer of ketchup over the top to create a glaze.
Bake in the preheated oven for 60-75 minutes, or until the internal temperature reaches 160°F (70°C).
Remove the meatloaf from the oven and let it rest for about 10-15 minutes before slicing.
Garnish with fresh parsley if desired, and serve with your favorite side dishes like mashed potatoes or roasted vegetables.
Notes
Let the meatloaf rest before slicing for better texture.
