Crockpot Salisbury Steak with Mushroom Gravy: A Comforting and Hearty Meal

In a large bowl, combine the ground beef, bread crumbs, milk, chopped onion, egg, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix everything together until just combined. Be careful not to overwork the mixture.
Shape the meat mixture into 4-6 patties, depending on the size you prefer.
Brown the Patties (optional but recommended for extra flavor):

Heat a skillet over medium-high heat and add a little oil.
Brown the patties on both sides for about 2-3 minutes per side, just to develop a nice crust. This step adds extra flavor but is optional. You can also skip this step and add the patties directly to the crockpot.
Prepare the Mushroom Gravy:

In the same skillet, add the sliced mushrooms and sauté for 5-7 minutes, until the mushrooms are softened and browned. If needed, add a little more oil.
Add the beef broth, onion soup mix, Worcestershire sauce, garlic powder, and bring to a simmer. Stir well to combine the soup mix into the broth.
Allow the gravy to cook for 3-5 minutes until it’s well mixed and slightly thickened. Taste for seasoning and adjust as needed.
Cook in the Crockpot:

Transfer the browned (or unbrowned) Salisbury steak patties to the bottom of the crockpot.
Pour the mushroom gravy mixture over the patties, ensuring they are well covered.
Cover the crockpot and cook on low for 6-7 hours, or on high for 3-4 hours, until the patties are tender and cooked through.
Finish and Serve:

About 30 minutes before serving, stir in the sour cream into the gravy to make it creamy. Taste the gravy and adjust seasoning if necessary with salt, pepper, or more Worcestershire sauce.
Serve the Salisbury steaks and gravy over mashed potatoes, rice, or egg noodles for a comforting meal.
