How Do You Make Salisbury Steak Casserole?

1. Preheat the oven:
   Begin by setting your oven to high broil so it’s ready when you need it.

2. Mix the beef ingredients:
   In a medium mixing bowl, combine ground beef, horseradish, garlic, Worcestershire sauce, garlic salt, pepper, and dry onion soup mix. Mix thoroughly using your hands or a large spoon until evenly combined.

3. Cook the beef and vegetables:
   Heat the olive oil in a large, oven-safe skillet. Add the beef mixture, along with mushrooms and onions. Cook over medium-high heat, stirring occasionally, until the meat is browned and the onions are tender.

4. Make the gravy:
   While the beef cooks, whisk together dry onion soup mix, beef broth, Worcestershire sauce, water, and cornstarch in a large bowl or measuring cup. Once smooth, pour the mixture into the skillet with the beef and vegetables. Continue cooking for about 2 minutes, stirring occasionally, until the gravy thickens.

5. Prepare the mashed potato topping:
   In a separate bowl, stir together heated mashed potatoes, cheese, butter, and half and half until smooth and creamy.

   

6. Assemble and broil:
   Spread the mashed potato mixture evenly over the beef and gravy. Then, place the skillet under high broil for 3–5 minutes, or until the top is golden and bubbling. To finish, sprinkle with fresh parsley and serve hot.

Tips for the Best Salisbury Steak Casserole

• Use lean beef to avoid excess grease in the gravy.

• Add richness: A splash of red wine in the gravy enhances flavor.

• Make ahead: Assemble the casserole early, refrigerate, and broil before serving.

• Switch it up: Try mashed cauliflower instead of potatoes for a lighter, low-carb version.

• Add crunch: Top with crispy fried onions or breadcrumbs before broiling.

With these simple tweaks, you’ll have a casserole that’s creamy, flavorful, and completely unforgettable.

Storage and Reheating

• Refrigerate: Store leftovers in an airtight container for up to 3 days.

• Freeze: Cool completely, wrap tightly, and freeze for up to 2 months.

• Reheat: Warm in a 350°F oven until heated through and bubbly.

Because this casserole reheats beautifully, it’s perfect for meal prepping or enjoying leftovers later in the week.

Frequently Asked Questions

Can I use ground turkey instead of beef?

Yes, you can! Ground turkey or chicken both make excellent substitutes, though the flavor will be milder.

What can I use instead of refrigerated mashed potatoes?

Homemade mashed potatoes work perfectly, but you can also use instant if you’re short on time.

Can I bake this instead of broiling?

Absolutely. Bake at 400°F for about 10–12 minutes, until the top turns golden and the cheese melts completely.
