Preheat your oven to 350°F (175°C) and prepare your baking sheet by lining it with parchment paper.

Mix the dry seasoning mix in a small bowl and set aside.

Create the topping by mixing ketchup, black pepper, and salt in another bowl.

Sauté onions, celery, carrots, and red bell pepper in olive oil for 3-4 minutes, then stir in half of the seasoning mix.

Combine the sautéed vegetable mixture with ground beef, tomato juice, and remaining seasoning mix in a large bowl.

Shape the meat mixture into a loaf on the baking sheet and brush the topping over it.

Bake in the preheated oven for 30 minutes, then rotate and bake for an additional 15-20 minutes until internal temperature reaches 160°F–165°F.

Let the meatloaf rest for at least 10 minutes before slicing and serving.
