In a large skillet, over medium heat, add the ground beef. Use a wooden spoon to break it apart as it cooks, ensuring it browns evenly. Cook for about 5-7 minutes until fully browned and no longer pink.

Once the beef is browned, drain any excess fat from the skillet. This helps to prevent the filling from being greasy.

Add the finely chopped onion and minced garlic to the skillet. Cook for an additional 3-4 minutes, stirring frequently, until the onion is translucent and softened.

Stir in the ketchup, Worcestershire sauce, yellow mustard, brown sugar, smoked paprika, salt, and black pepper. Mix well to combine all ingredients thoroughly.

Reduce the heat to low and let the mixture simmer for about 10 minutes, stirring occasionally. This allows the flavors to meld together and the sauce to thicken slightly.

While the filling simmers, lightly toast the hamburger buns on a separate skillet or in a toaster. This adds a nice texture and prevents the buns from becoming soggy.

Once the filling is ready, spoon a generous amount onto the bottom half of each toasted bun.

Top with sliced pickles if desired, then place the top half of the bun over the filling.

Serve immediately while hot, with extra napkins on hand!
