Ingredients:
For the Casserole Base:
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, cremini or button mushrooms, can be used interchangeably
3 cloves Garlic, use fresh garlic for best results
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
For the Creamy Layer:
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
For Assembly:
4 pieces Hamburger Buns, gluten-free buns can be used for a gluten-free version
2 tbsp Olive Oil, adds richness to the dish
Salt and Pepper to taste, essential for seasoning
1 tbsp Fresh Parsley, optional, garnish for freshness and color

Instructions:
Preheat your oven to 350°F (175°C) to ensure it’s hot and ready for baking. Sauté in a large skillet by heating olive oil over medium heat. Add the ground beef, breaking it up with a spatula until it’s browned and cooked through, roughly 5-7 minutes. Season with salt and pepper, then set aside. Cook the onions and mushrooms in the same skillet until softened, around 5-7 minutes. Add minced garlic and sauté for an additional minute until fragrant. Return the cooked beef to the skillet. Mix in Worcestershire sauce, soy sauce, Dijon mustard, and beef broth. Let this simmer for 5 minutes, then remove from heat and stir in sour cream. Cube the hamburger buns and place them at the bottom of a casserole dish. Pour the savory beef mixture over, spreading it evenly. Top with shredded Swiss cheese, then bake for 25-30 minutes until the cheese is melty and golden brown. Garnish with fresh parsley before serving.
