Method
Preparation
Preheat the oven to 375°F (190°C).
In a large skillet over medium heat, brown the ground beef with the chopped onion and sliced mushrooms. Season with salt and pepper. Cook until the beef is no longer pink and the onions are translucent.
In a mixing bowl, combine the can of cream of mushroom soup and the cup of beef broth. Stir until smooth.
In a 9x13-inch baking dish, layer the browned beef, onion, and mushroom mixture evenly across the bottom.
Spread the frozen mixed vegetables over the beef layer.
Pour the soup and broth mixture over the vegetables and beef, dispersing it evenly.
Spread the prepared mashed potatoes on top of everything, smoothing the surface with a spatula.
Baking
Bake for 30–35 minutes until the casserole is heated through and the mashed potato topping is slightly golden.
Let rest for 5–10 minutes before serving to allow the layers to set.
Can freeze the assembled casserole (up to the mashed potato step) for 2 months. Bake from frozen at 375°F (190°C) for up to 60–75 minutes. Use fresh vegetables instead of frozen if preferred, sautéing firmer ones first. Adjust seasoning for each layer.
