Preheat the oven to 350°F (175°C).

In a skillet, brown the ground beef over medium heat until fully cooked. Drain excess fat.

Add chopped onion and minced garlic to the skillet and sauté until softened.

In a large bowl, combine the beef mixture with carrots, potatoes, and green beans.

In another bowl, mix together the cream of mushroom soup, beef broth, Worcestershire sauce, salt, and pepper.

Pour the sauce over the beef and vegetable mixture and stir to combine.

Transfer the mixture to a casserole dish and spread evenly.

Sprinkle shredded cheddar cheese and bread crumbs on top if using.

Cover with foil and bake in the preheated oven for 60 minutes.

Remove the foil and bake for an additional 15-20 minutes until the top is golden brown.

Let the casserole cool for a few minutes before serving.

Serve warm and enjoy!
