**Ingredients:**

* 600 grams (1.32 pounds) ground beef
* 1/2 onion, finely chopped
* 1/4 cup bread crumbs
* 1 egg, beaten
* 1/4 cup milk
* 1 tablespoon Worcestershire sauce
* 1 teaspoon garlic powder
* 1/2 teaspoon salt
* 1/4 teaspoon black pepper

**Instructions:**

1. In a large bowl, combine all the ingredients.
2. Mix well until evenly combined.
3. Divide the mixture into 4 equal portions and shape into patties.
4. Grill or pan-fry the patties over medium heat until cooked through.
5. Serve on hamburger buns with your favorite toppings.

**Tips:**

* For a juicier patty, use ground beef with at least 80% lean content.
* To make the patties even more flavorful, add your favorite herbs and spices to the mixture.
* If you don’t have bread crumbs, you can use crackers or oatmeal instead.
* To prevent the patties from sticking to the grill, brush them with a little oil before cooking.
* For a healthier option, bake the patties in a preheated oven at 400°F (200°C) for 15-20 minutes, or until cooked through.
