Preheat your oven to 375°F (190°C) and line a loaf pan or baking sheet with foil.

Cook the bacon in a skillet over medium heat until crispy, about 6-8 minutes. Remove and crumble.

In the same skillet, sauté the chopped mushrooms for 5-7 minutes until browned.

In a large bowl, combine ground beef, eggs, breadcrumbs, diced onion, minced garlic, Worcestershire sauce, salt, and pepper.

Transfer the meat mixture to the prepared baking sheet and shape into a loaf, press Swiss cheese cubes into the center, and top with sautéed mushrooms and crumbled bacon.

Bake for 45-55 minutes until the internal temperature reaches 160°F (71°C).

Let the meatloaf rest for 10 minutes before slicing and serve warm with fresh parsley.
