Ingredients
For the Salisbury Steak Patties:
* 1.5 pounds Ground Beef (I prefer 80/20 for flavor)
* 1/2 cup breadcrumbs (panko or regular)
* 1 large egg, lightly beaten
* 1/4 cup finely chopped onion
* 2 cloves garlic, minced
* 1 tablespoon Worcestershire sauce
* 1 teaspoon dried thyme
* 1/2 teaspoon salt
* 1/4 teaspoon black pepper
For the Mushroom Gravy:
* 2 tablespoons olive oil
* 8 ounces cremini mushrooms, sliced
* 1 medium onion, chopped
* 2 cloves garlic, minced
* 1/4 cup all-purpose flour
* 3 cups beef broth
* 1 tablespoon Worcestershire sauce
* 1 teaspoon dried thyme
* 1/2 teaspoon salt
* 1/4 teaspoon black pepper
* 1/2 cup heavy cream (optional, but adds richness)
For the Mashed Potato Topping:
* 4 pounds Yukon Gold potatoes, peeled and quartered.
* 1/2 cup milk (or cream, for extra richness)
* 4 tablespoons butter
* Salt and pepper to taste
What is the step-by-
Step 1: Preheat & Prep Pan
Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch casserole dish. This step is super important to prevent sticking and make serving a breeze. I always use a cooking spray with flour in it to ensure nothing sticks.
Step 2: Mix Dry Ingredients
In a large bowl, combine ground beef, breadcrumbs, egg, onion, garlic, Worcestershire sauce, thyme, salt, and pepper. Gently mix everything together with your hands until just combined. Do not overmix, as this can make the patties tough. The key is to incorporate everything evenly without compacting the beef.
Step 3: Shape Patties
I like to wet my hands slightly to prevent the meat from sticking. Divide the mixture into 6-8 equal portions and shape them into oval-shaped patties, about 1/2 inch thick. Don’t worry about them being perfectly shaped; a little rustic charm is perfectly fine!
Step 4: Sear Patties
In a large skillet, heat the olive oil over medium-high heat. Sear the patties for about 3-4 minutes per side, until nicely browned. Do you need to cook them all the way through at this point, as they will finish cooking in the oven? I’ve found that searing in batches prevents overcrowding the pan and ensures even browning.
Step 5: Make the Mushroom Gravy
Remove patties from the skillet and set them aside. In the same skillet, add the sliced mushrooms and chopped onion. Cook until softened and lightly browned, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant. This creates the flavor base for your gravy, so don’t rush this step!
Step 6: Thicken the Gravy
Sprinkle the flour over the mushroom mixture and cook for 1-2 minutes, stirring constantly. This creates a roux, which will thicken the gravy. Gradually whisk in the beef broth, Worcestershire sauce, thyme, salt, and pepper. Bring to a simmer and cook until the gravy has thickened, about 5 minutes. If you like a creamier gravy, stir in the heavy cream during the last minute of cooking. I learned the hard way that adding the flour too quickly can cause lumps. Patience is key!
Step 7: Layer the Casserole
Arrange the seared patties in the prepared casserole dish. Pour the mushroom gravy over the patties, making sure they are evenly coated.
Step 8: Prepare the Mashed Potatoes
While the gravy is simmering, cook the potatoes in a large pot of boiling salted water until tender, about 15-20 minutes. Drain the potatoes and return them to the pot. Add the butter and milk and mash until smooth and creamy. Season with salt and pepper to taste. I sometimes add a little garlic powder to my mashed potatoes for extra flavor.
Step 9: Top with Mashed Potatoes and Bake
Spread the mashed potatoes evenly over the patties. You can create swirls or patterns with a fork for a more decorative look. Bake in the preheated oven for 20-25 minutes, or until the potatoes are golden brown and the gravy is bubbly. Let the casserole rest for a few minutes before serving. How do you get the flavors to meld together?

How can I take my Salisbury Steak Casserole to the next level?What is the best ground beef?Use 80/20 ground beef for the most flavor. The fat adds richness and keeps the patties from drying out. Don’t be afraid to experiment with different types of ground beef. I also use ground turkey or chicken to make the best patties.
For Super Flavorful Patties:Why don’t I skip the Worcestershire sauce? It adds a depth of flavor that you just can’t get from anything else. I’ve found that marinating the patties for 30 minutes before searing really intensifies the flavors.
How do I make Creamy Mushroom Gravy?Use a combination of cremini and shiitake mushrooms for a more complex flavor. Sauté until they are deeply browned to bring out their earthy notes. A splash of sherry or Madeira wine adds a touch of elegance. If you like thicker gravy, whisk in a cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) at the end of cooking.

Freezing:For longer storage, you can freeze the casserole for up to 2-3 months. Wrap it tightly in plastic wrap and then in aluminum foil to prevent freezer burn. I always find freezing in portions gives great results.
Reheating:Preheat your oven to 350°F (175°C). Cover the casserole with foil and bake for 20-25 minutes, or until heated through. You can also reheat individual portions in the microwave. If the mashed potatoes are dry, add a splash of milk or broth before reheating.
