A Midwest loose meat sandwich features seasoned ground beef on a soft bun for a simple, protein-rich family meal. This Iowa classic is like a deconstructed burger that's quick and satisfying.
In a large skillet over medium-high heat, crumble the ground beef and cook until it just starts to brown, about 3 minutes. Stir regularly to break it into small pieces.
Add the finely chopped onion to the pan and continue to cook, stirring frequently, until onions are translucent and beef is no longer pink, about 4–5 more minutes.
Reduce heat to medium. Add beef broth, Worcestershire sauce, yellow mustard, salt, and black pepper. Stir well to combine.
Simmer uncovered, stirring occasionally and breaking up any clumps, until most of the liquid has evaporated and the beef mixture is moist but not wet, about 10–12 minutes.
Spoon the seasoned beef mixture onto the bottom half of each soft hamburger bun. Top with dill pickle chips, add the top bun, and serve immediately for best texture.
