What Kind of Ground Beef Should I Use?
For this Salisbury steak casserole, lean ground beef with about 90-93% lean meat is your best bet. While you could use a higher fat content like 80/20, the extra grease might make your casserole too heavy and potentially greasy. Regular ground beef will work in a pinch, but you’ll want to drain off the excess fat after browning to keep your casserole from becoming too oily. If you’re watching your red meat intake, you could even swap in ground turkey, though it will change the classic Salisbury steak flavor a bit. Just make sure to break up the meat into small, even pieces while browning for the best texture in your finished casserole.
Options for Substitutions
This comforting casserole is pretty adaptable – here are some helpful swaps you can try:
- Ground beef: You can use ground turkey or ground pork instead of beef. If using turkey, add 1 tablespoon of olive oil to the mix since it’s leaner than beef.
- Mashed potatoes: No leftover mashed potatoes? Use instant mashed potatoes, or try topped with tater tots instead. You could even use mashed cauliflower for a lower-carb option.
- French onion soup: If you’re out of French onion soup, mix beef broth with 1/2 cup of caramelized onions as a substitute.
- French-style green beans: Regular cut green beans work fine here, or swap in another veggie like peas, corn, or mixed vegetables.
- Dry mustard: Regular yellow mustard works too – just use 1 tablespoon instead of the dry mustard.
- Onion soup mix: If you don’t have the packet mix, combine 3 tablespoons of dried onion flakes, 2 teaspoons of beef bouillon granules, and 1/4 teaspoon of onion powder.
Watch Out for These Mistakes While Cooking
The biggest challenge when making Salisbury steak casserole is ending up with dry, tough meat patties – to avoid this, don’t overmix the ground beef mixture or press the patties too firmly, as this can make them dense and chewy. Another common mistake is rushing the gravy process – make sure to let it simmer until it reaches the right consistency, as a thin gravy will make your casserole watery and affect the overall texture of your mashed potato layer. When layering the casserole, be careful not to spread the mashed potatoes too thin or unevenly, as this can lead to uneven heating and cold spots – aim for a consistent layer about 1-inch thick. For the best results, let your casserole rest for 10-15 minutes after baking to allow the gravy to settle and thicken, making it easier to serve neat portions.
What to Serve With Salisbury Steak Casserole?
Since this casserole already includes meat, potatoes, and green beans, you’ve got most of your bases covered – but there are still some tasty sides that can round out the meal! A simple dinner roll or piece of crusty bread is perfect for soaking up the rich gravy. If you want to add more vegetables, a fresh garden salad with tomatoes and cucumbers provides a nice contrast to the warm, hearty casserole. For those who love extra veggies, some glazed carrots or roasted Brussels sprouts would fit right in with the comfort food theme of this dish.
Storage Instructions
Keep Fresh: This cozy Salisbury steak casserole will stay good in the fridge for up to 4 days when stored in an airtight container. The flavors actually get better after a day or two as everything melds together, making it perfect for meal prep!
Freeze: Want to save some for later? This casserole freezes really well! Let it cool completely, then pop it in a freezer-safe container. It’ll keep for up to 3 months. Pro tip: divide it into smaller portions before freezing for easy single servings.
Reheat: To warm up your casserole, cover it with foil and heat in a 350°F oven for about 20-25 minutes, or until heated through. If you’re in a hurry, the microwave works too – just heat in 1-minute intervals, stirring between each, until it’s nice and hot. Add a splash of beef broth if it seems a bit dry.

Ingredients
For the base:
- 2 to 3 cups prepared mashed potatoes
- 1 can French-style green beans
For the beef mixture:
- 1.5 lb lean ground beef
- 1/3 can French onion soup
- 1/8 tsp black pepper
For the sauce:
- optional: canned mushroom slices (drained)
- 1/4 cup ketchup
- 2/3 can French onion soup
- 3 tbsp all-purpose flour
- 2 tbsp Worcestershire sauce
- 1 packet dry onion soup mix (Lipton’s Onion Soup Mix is a good choice)
- 1/2 cup water
- 1 can cream of mushroom soup (I use Campbell’s Cream of Mushroom)
- 1 tsp dry mustard
Step 1: Prepare Ingredients and Preheat Oven
Preheat your oven to 350°F (175°C).
If you do not have mashed potatoes prepared, this is the time to make them.
You can use your favorite mashed potato recipe or an instant version if you prefer.
Step 2: Cook Ground Beef Mixture
In a deep skillet, combine 1/3 can of French onion soup, ground beef, and a sprinkle of pepper.
Cook over medium heat until the ground beef is cooked through.
If using higher-fat meat, be sure to drain the excess liquids once done.
This will form a flavorful base for our dish.
Step 3: Prepare the Soup Mixture
While the ground beef is cooking, in a small bowl, combine the remaining French onion soup, cream of mushroom soup, dry onion soup mix, and flour.
Mix vigorously until well combined and there are no lumps of flour.
To this mixture, add ketchup, water, Worcestershire sauce, mustard powder, and mushrooms.
Stir until everything is thoroughly mixed.
Step 4: Assemble the Dish
If your skillet is oven-safe and has no plastic handles, you can layer everything directly in the skillet.
If not, transfer the cooked ground beef to a 9 x 13 baking pan.
Pour the prepared soup mixture evenly over the ground beef.
Next, dump and spread the green beans over the ground beef and soup layers.
Finally, top it all with a smooth layer of mashed potatoes, ensuring the surface is even.
Step 5: Bake and Serve
Place the assembled dish in the preheated oven and bake for 20 minutes, or until the top is lightly browned and everything is heated through.
Once done, remove from the oven and let it sit for a couple of minutes.
Serve immediately for a comforting and hearty meal.
Enjoy!
