Combine ground beef, minced garlic, salt, black pepper, A-1 sauce, ketchup, Worcestershire sauce, seasoned breadcrumbs, and egg in a large mixing bowl. Mix thoroughly until evenly incorporated. Shape mixture into 4 uniform oval patties.
02 -
Heat vegetable oil in a large skillet over medium-high heat. Sear the patties for approximately 3 minutes per side until both sides are well browned. Transfer patties to a plate and set aside.
03 -
Remove excess fat from the pan and reduce heat to medium-low. Melt unsalted butter in the skillet. Add sliced onions and sauté for 4–5 minutes until softened and translucent.
04 -
Sprinkle flour over the cooked onions and stir continuously for about 2 minutes to form a roux.
05 -
Increase heat to medium. Gradually pour in beef broth while stirring to prevent lumps. Add Worcestershire sauce, salt, and black pepper. Scrape the bottom of the pan to release browned bits. Bring to a gentle simmer.
06 -
Return browned patties to the skillet, nestling them into the gravy. Allow the contents to return to a simmer, then reduce heat to medium-low. Cover and cook for 20 minutes, turning the patties once.
07 -
Remove lid and simmer uncovered for an additional 5 minutes to thicken the gravy. Ensure the patties are fully cooked by checking their internal temperature. Plate patties with gravy and serve immediately.
