A comforting and flavorful Salisbury steak recipe with a rich onion gravy, perfect for a hearty meal.
Combine the ground beef, egg, milk, salt, and pepper in a mixing bowl.
Mix gently to avoid overworking the meat, which can make the patties tough.
Form the mixture into 4 equal-sized patties.
Make a small indentation in the center of each patty to help them cook evenly.
Heat a nonstick skillet over medium heat and cook the patties for 2 minutes on each side until browned.
Browning the patties adds flavor and helps seal in the juices.
Transfer the patties to a casserole dish.
Arrange the patties in a single layer for even cooking.
In the same skillet, sauté the sliced onion until caramelized.
Stir frequently to prevent the onions from burning.
Dissolve the beef bouillon in 1.5 cups of water and add to the skillet.
Use warm water to help the bouillon dissolve more easily.
Mix the cornstarch with a small amount of water to form a slurry, then add to the skillet.
Stir constantly to avoid lumps forming in the gravy.
Pour the gravy over the patties in the casserole dish.
Ensure the patties are evenly coated with the gravy.
Bake the dish in a preheated oven at 350°F (175°C) for 30 minutes.
Cover the dish with foil to prevent the gravy from drying out.
Serve the patties topped with caramelized onions and enjoy.
Garnish with fresh parsley for a touch of color and freshness.
