In a large skillet over medium-high heat, brown your ground beef with diced onion until the meat is cooked through and the onions are translucent. Add your minced garlic for the final minute, letting its aroma bloom. Drain any excess fat.

Into your meat mixture, stir the diced tomatoes, cream of mushroom soup, beef broth, and sour cream. Season with Italian herbs, paprika, salt, and pepper. Let this simmer gently, allowing all those flavors to become best friends.

Fold your cooked pasta shells into the rich sauce until every shell is beautifully coated. Transfer this mixture to your prepared baking dish, then blanket it with your duo of shredded cheeses.

Let your casserole bake for 20-25 minutes, until the cheese has melted into a golden, bubbly crust.

Finish with a sprinkle of fresh parsley, adding color and freshness to your bubbling masterpiece. Serve while hot and cheese is at its melty best!
