Garlic Mashed Potatoes:
3. Place potatoes in a large pot and cover with water. Bring to a boil and cook until tender, about 20 minutes. Add garlic to the pot in the last 5 minutes of cooking.
Drain potatoes and garlic, then return to the pot. Add milk, butter, salt, and pepper. Mash until smooth and creamy.
Mushroom & Onion Gravy:
5. In the same skillet used for the patties, add additional olive oil if needed. Add onion and mushrooms and cook until softened, about 5 minutes.
Sprinkle flour over the mushrooms and onions, stirring to coat. Gradually add beef broth and Worcestershire sauce, stirring constantly. Cook until the gravy has thickened, about 5 minutes. Season with salt and pepper.
Return the Salisbury steaks to the skillet, spooning the gravy over the top. Simmer for an additional 5 minutes to reheat the steaks.
Serve the Salisbury steaks with a generous helping of garlic mashed potatoes and top with the mushroom and onion gravy.
