Creating this delightful Amish Hamburger Steak Bake is a breeze if you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C).
2. Cook the Ground Beef: In a skillet over medium heat, brown the ground beef until fully cooked. Drain excess grease.
3. Sauté Vegetables: Add the chopped onion, mushrooms, and minced garlic to the skillet. Sauté for about 5 minutes until they soften.
4. Mix Ingredients: In a bowl, combine cream of mushroom soup, beef broth, Worcestershire sauce, salt, pepper, paprika, and garlic powder. Mix until well combined.
5. Combine: Pour this mixture over the cooked beef and vegetables. Stir in the frozen mixed vegetables and ensure they are evenly distributed.
6. Prepare Baking Dish: Transfer the beef and vegetable mixture to a 9×13-inch baking dish, spreading it evenly.
7. Top with Mashed Potatoes: Dollop the prepared mashed potatoes over the beef mixture, spreading them to cover the top completely.
8. Sprinkle Cheese (Optional): If using, sprinkle shredded cheddar cheese over the mashed potatoes for an extra creamy finish.
9. Bake: Cover the baking dish with aluminum foil and bake for 30 minutes. Remove the foil and bake for an additional 10-15 minutes, allowing the top to brown slightly.
10. Cool and Serve: Once cooked, remove from the oven and let it rest for a few minutes before serving.

This straightforward procedure ensures the flavors meld beautifully, providing you with a dish that’s both comforting and delicious.
