In a large skillet over medium heat, brown the ground beef until fully cooked. Drain excess fat.
Add the diced onion and minced garlic to the skillet. Sauté until the onion is translucent, about 5 minutes.
Stir in the rice and cook for an additional 2 minutes, allowing it to lightly toast.
Pour in the beef broth, drained diced tomatoes, and frozen mixed vegetables. Season with paprika, Italian seasoning, salt, and pepper.
Stir the mixture well and bring to a simmer. Cover the skillet and let it cook for about 15 minutes, or until the rice is tender and has absorbed most of the liquid.
Remove the skillet from heat. Stir in 1.5 cups of the shredded cheddar cheese until melted and well combined.
Transfer the mixture to a greased 9x13 inch baking dish. Sprinkle the remaining 0.5 cup of cheddar cheese on top.
Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden.
Once done, remove from the oven and let it cool for 5 minutes. Garnish with chopped parsley before serving.
