Ingredients

Scale

Meat and Vegetables

  • 1 lb Ground Beef (can be swapped for ground turkey, chicken, or plant-based meat)
  • 1 Onion (yellow onion or shallots work well as substitutes)
  • 8 oz Mushrooms (crimini or button mushrooms can be used interchangeably)
  • 3 cloves Garlic (use fresh garlic for best results)

Liquids and Sauces

  • 1 cup Beef Broth (chicken broth can be used for a lighter flavor)
  • 1 tbsp Worcestershire Sauce (essential for a savory kick)
  • 2 tbsp Soy Sauce (adjust quantity for lower sodium versions)
  • 1 tbsp Dijon Mustard (complements the rich flavors)

Dairy and Bread

  • 6 oz Swiss Cheese (cheddar, mozzarella, or any melty cheese can be used as alternatives)
  • 1 cup Sour Cream (Greek yogurt can be used as a healthier option)
  • 4 pieces Hamburger Buns (gluten-free buns can be used for a gluten-free version)

Other

  • 2 tbsp Olive Oil (adds richness to the dish)
  • to taste Salt (essential for seasoning)
  • to taste Pepper (essential for seasoning)
  • 1 tbsp Fresh Parsley (optional garnish for freshness and color)

Instructions

  1. Preparation Steps: Gather all ingredients and preheat your oven to 350°F (175°C) to ensure it’s ready for baking when the casserole is assembled.
  2. Sauté Ground Beef: Heat olive oil in a large skillet over medium heat. Add ground beef, breaking it up with a spatula. Cook until browned and fully cooked through, about 5-7 minutes. Season with salt and pepper. Once cooked, remove the beef from the skillet and set aside.
  3. Cook Onions and Mushrooms: In the same skillet, add onions and mushrooms. Sauté until they become soft and slightly browned, approximately 5-7 minutes. Add minced garlic and cook for an additional minute until fragrant.
  4. Combine Ingredients in Skillet: Return the cooked ground beef to the skillet with the vegetables. Stir in Worcestershire sauce, soy sauce, Dijon mustard, and beef broth. Allow the mixture to simmer gently for 5 minutes to blend flavors well. Remove from heat and fold in sour cream to add creaminess.
  5. Assemble the Casserole: Cube the hamburger buns and place them evenly in the bottom of a casserole dish. Pour the beef and mushroom mixture over the bread cubes and spread it out evenly.
  6. Add Cheese and Bake: Sprinkle shredded Swiss cheese over the top of the casserole. Place in the preheated oven and bake for 25-30 minutes, or until the cheese is melted, bubbly, and golden brown.
  7. Garnish and Serve: Once baked, remove the casserole from the oven and sprinkle with fresh parsley for a pop of color and freshness before serving.

Notes

  • You can substitute ground beef with ground turkey, chicken, or plant-based meat for different dietary preferences.
  • Cheese alternatives like cheddar or mozzarella work well if Swiss cheese is unavailable.
  • Greek yogurt can be used instead of sour cream for a healthier, tangy variant.
  • For a gluten-free version, use gluten-free hamburger buns.
  • Adjust soy sauce quantity if you prefer a lower sodium dish.
  • Leftovers keep well refrigerated for up to 3 days and reheat nicely in the oven or microwave.
