Cheesy Shepards Pie Potato Casserole

0 Peel and slice the potatoes, then boil them over medium-high heat until they’re just fork tender. At the same time, heat a large skillet over medium high and cook the ground beef with the onions until the meat is browned all the way through. Drain off any extra grease.
1 Season the beef with bouillon powder, onion powder, garlic powder, salt, and black pepper. Stir in the Worcestershire sauce and tomato paste until evenly combined, letting it cook for about 1–2 minutes to deepen the flavor.
2 Add the butter and let it melt, then sprinkle in the flour and stir to form a thick mixture. Cook this for 2–3 minutes, stirring occasionally. Pour in the beef broth, then add the mixed vegetables and cooked potatoes, mixing everything together well.
3 Let the mixture come to a light simmer, then stir in the shredded parmesan cheese until it melts smoothly into the dish. Serve hot and enjoy!
