Step 1: Prepare the Loose Meat Filling

1. Cook the Beef: Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it into small crumbles with a wooden spoon or spatula. Stir occasionally to ensure even browning.
2. Add Onions: Once the beef starts to brown, add the diced onions to the skillet. Cook for 3-4 minutes or until the onions become translucent.
3. Season the Beef: Stir in the garlic powder, onion powder, smoked paprika, salt, and black pepper. Mix well to coat the beef with the seasonings.
4. Deglaze the Pan: Add the Worcestershire sauce and beef broth (or water) to the skillet. Stir to combine, scraping the bottom of the pan to release any browned bits for extra flavor.
5. Simmer: Reduce the heat to low and let the mixture simmer for 5-7 minutes, stirring occasionally. The liquid should reduce, leaving the beef moist but not saucy.

Step 2: Toast the Buns (Optional)

6. Toast for Texture: While the beef is simmering, lightly toast the hamburger buns on a skillet or in a toaster oven for extra texture and flavor.

Step 3: Assemble the Sandwiches

7. Pile on the Meat: Spoon a generous portion of the loose meat mixture onto the bottom half of each bun.
8. Add Toppings: Layer with your preferred toppings, such as dill pickles, mustard, chopped onions, or a slice of cheese.
9. Serve Immediately: Place the top bun over the filling and serve the sandwiches warm with your favorite sides.
