In a large bowl, combine ground beef, breadcrumbs, minced onion, Italian seasoning, ketchup, Worcestershire sauce, egg, minced garlic, salt, and pepper. Mix gently until evenly incorporated without overworking to maintain tenderness.

Divide the beef mixture into four equal portions. Form each into a thick oval patty, pressing edges firmly to hold shape during cooking.

Heat olive oil in a large skillet over high heat until shimmering. Add patties and cook undisturbed for approximately 5 minutes until the bottom is golden brown. Flip and cook an additional 4 to 5 minutes. Remove from skillet and cover with foil to keep warm.

Reduce heat to medium. Melt butter in the same skillet, then add sliced mushrooms and chopped onions. Season lightly with salt and pepper. Sauté for 5 to 6 minutes, stirring frequently until vegetables are golden and tender.

Add minced garlic to the pan and stir for 30 seconds until fragrant. Sprinkle flour evenly over the mixture and continuously stir for 1 minute to eliminate raw flour taste, creating a thick paste.

Deglaze the pan by adding a small portion of beef broth and whisking to loosen browned bits. Gradually add remaining broth while whisking to prevent lumps. Stir in Worcestershire and soy sauces. Simmer for 2 to 3 minutes until sauce thickens.

Return the browned patties to the skillet, nestling them into the mushroom gravy. Reduce heat to low, cover, and simmer gently for 5 to 7 minutes to meld flavors and ensure the patties are heated through.

Sprinkle fresh chopped parsley over the patties and gravy. Serve immediately with preferred sides such as mashed potatoes, steamed vegetables, or rice.
