Preheat your oven to 350°F (175°C) and grease a casserole dish or line a baking sheet with parchment paper.

In a mixing bowl, combine ground beef, breadcrumbs, chopped onion, minced garlic, beaten eggs, ketchup, Worcestershire sauce, thyme, oregano, and season with salt and pepper. Mix gently until just combined.

Shape the mixture into a loaf and place it in the prepared dish.

Bake the meatloaf in the preheated oven for 50-60 minutes until a meat thermometer reads 160°F (71°C).

While the meatloaf is baking, melt the butter in a skillet over medium heat.

Add the sliced mushrooms and cook until golden brown and fragrant, about 5-7 minutes.

Sprinkle flour over the mushrooms, stirring constantly for about 2 minutes.

Gradually whisk in the beef broth and cream, stirring until the gravy thickens, about 5-7 minutes. Season to taste.

Once the meatloaf is done, let it rest for a few minutes before slicing it into thick portions.

Ladle the mushroom gravy over each serving and enjoy!
