Is McDonald’s beef burger real beef?

Yes, large companies and hotels have strict food systems. Generally, for hamburgers and beef burger patties in hotels, you first prepare minced beef, minced onions, red wine eggs, and toast soaked in milk. Sauté the onions with butter until fragrant, add thyme, black pepper, and finally spray red wine, let cool, then add minced beef, toast, and eggs, stir well together, then divide into balls and press into patties and freeze. Finally, it is fried and served with breaded vegetables and it becomes a beef burger.
