Salisbury Steak with Garlic Mashed Potatoes & Mushroom-Onion Gravy
Introduction
When it comes to comfort food, few dishes compare to a hearty plate of Salisbury steak smothered in rich mushroom and onion gravy, paired with creamy garlic mashed potatoes. It’s warm, filling, and packed with flavor. Unlike a classic steak, Salisbury steak is made with seasoned ground beef patties, simmered slowly in gravy until tender and juicy. Served with buttery mashed potatoes, this dish is the ultimate family dinner.
Ingredients
For the Salisbury Steak
1 lb (500 g) ground beef (80/20 blend recommended)
1 large egg
1/3 cup breadcrumbs
1 small onion, finely grated
2 garlic cloves, minced
1 tbsp ketchup
1 tsp Worcestershire sauce
1 tsp Dijon mustard (optional for extra depth)
1/2 tsp salt
1/2 tsp black pepper
2 tbsp olive oil or butter for cooking
For the Mushroom & Onion Gravy
2 tbsp butter
1 large onion, thinly sliced
8 oz (250 g) mushrooms, sliced
2 tbsp all-purpose flour
2 cups beef broth (or chicken broth)
1 tsp Worcestershire sauce
1/2 tsp dried thyme (optional)
Salt & pepper to taste
For the Garlic Mashed Potatoes
2 lbs (1 kg) potatoes (Russet or Yukon Gold work best)
4 garlic cloves, peeled
1/2 cup warm milk (or heavy cream for richer flavor)
4 tbsp unsalted butter
Salt & black pepper
Instructions
1. Make the Salisbury Steak Patties
In a large bowl, combine ground beef, egg, breadcrumbs, onion, garlic, ketchup, Worcestershire sauce, mustard, salt, and pepper.
Mix until just combined (don’t overmix or the patties will be tough).
Shape into 4–6 oval patties.
Heat olive oil or butter in a skillet over medium heat.
Sear patties on both sides until browned, about 3–4 minutes per side. Remove and set aside (they’ll finish cooking in the gravy).
2. Prepare the Gravy
In the same skillet, melt butter. Add onions and cook until softened and golden, about 5 minutes.
Add mushrooms and cook until they release their liquid and turn golden brown.
Sprinkle in the flour, stirring well to coat.
Slowly pour in beef broth while whisking to avoid lumps.
Stir in Worcestershire sauce, thyme, salt, and pepper.
Return the patties to the skillet. Simmer on low heat for 15 minutes, until the gravy thickens and the patties are cooked through.
3. Make the Garlic Mashed Potatoes
Peel and chop the potatoes into even chunks.
Place in a pot with salted water and add garlic cloves.
Boil until potatoes are tender (about 20 minutes).
Drain, then mash with butter.
Add warm milk gradually, mixing until smooth and creamy.
Season with salt and pepper.
Serving
Spoon mashed potatoes onto plates.
Place Salisbury steak on top.
Generously ladle mushroom and onion gravy over everything.
Garnish with fresh parsley if desired.
Tips for Success
Use ground beef with some fat (at least 15%) to keep the patties juicy.
Don’t skip the sear — browning the patties adds flavor to both the meat and the gravy.
For creamier mashed potatoes, warm the milk before adding.
You can make this ahead of time — it reheats beautifully.
