Step-by-Step Instructions
Prepare the Beef Mixture
Add the ground beef, breadcrumbs, egg, Worcestershire sauce, garlic powder, onion powder, salt, and black pepper to a large bowl.
Mix gently with clean hands or a fork until the ingredients are evenly incorporated.
Do not overmix the meat. Mixing too aggressively can make the finished Salisbury steaks dense instead of tender.
Shape the Patties
Divide the mixture into 4–6 portions.
Shape each portion into an oval patty approximately 3/4-inch thick.
Make the patties slightly larger than you want them to be because they will shrink somewhat during cooking.
Optional: Brown the Patties
For extra flavor, heat a large skillet over medium-high heat and lightly brown the patties for approximately 2 minutes per side.
You do not need to cook them through at this stage.
This step is optional, but browning creates a deeper, more savory flavor and improves the appearance of the finished steaks.
Prepare the Slow Cooker
Place the sliced onions and mushrooms in the bottom of the slow cooker.
Arrange the Salisbury steak patties over the vegetables.
Make the Gravy Mixture
In a bowl, whisk together the beef broth, brown gravy mix, ketchup, and Dijon mustard until the gravy mix is thoroughly dissolved.
Pour the mixture evenly over the beef patties, mushrooms, and onions.
Slow Cook
Cover the slow cooker with its lid.
Cook on LOW for 4–5 hours, or until the beef patties are cooked through and tender.
Avoid opening the lid repeatedly because this allows heat to escape and can increase the cooking time.
Thicken the Gravy
If the gravy needs to be thicker, carefully remove the Salisbury steaks from the slow cooker.
Mix 1 tablespoon cornstarch with 1 tablespoon cold water until smooth.
Stir the slurry into the hot gravy.
Cover and cook on HIGH for approximately 10–15 minutes, or until the gravy reaches your preferred consistency.
Return the steaks to the gravy before serving.
Serve
Spoon plenty of mushroom gravy over each Salisbury steak.
Serve immediately with your favorite side dishes.
Best Tips
Choose ground beef with enough fat to keep the Salisbury steaks moist and flavorful. An 80/20 blend works particularly well.
Mix the meat gently and only until combined. Overworking the mixture can result in firm, tough patties.
Browning the patties before slow cooking is optional, but it gives the dish a richer flavor.
Slice the mushrooms fairly thickly so they maintain some texture during the long cooking process.
For a smoother gravy, whisk the gravy mixture thoroughly before adding it to the slow cooker.
If the gravy becomes thicker than desired, stir in a small amount of warm beef broth before serving.
Best Ingredient Options
Ground Beef: An 80/20 blend provides excellent flavor and moisture. Leaner ground beef can also be used if preferred.
Mushrooms: Cremini mushrooms provide a deeper flavor, while white mushrooms offer a milder taste.
Onions: Yellow onions are ideal, but white or sweet onions can also work.
Breadcrumbs: Plain breadcrumbs are perfect for this recipe. Seasoned breadcrumbs can add additional flavor.
Beef Broth: Regular or low-sodium beef broth can be used. If using regular broth, taste the gravy before adding additional salt.
Recipe Variations
🧅 Caramelized Onion Salisbury Steak
Use extra sliced onions and sauté them until golden before adding them to the slow cooker for a richer onion flavor.
🍄 Extra Mushroom Salisbury Steak
Double the mushrooms if you love a mushroom-heavy gravy.
🧀 Cheesy Salisbury Steak
Add a small amount of shredded cheese over the cooked steaks just before serving and allow it to melt.
🌿 Herb Salisbury Steak
Add dried thyme, parsley, or Italian seasoning to the beef mixture for an aromatic variation.
🥔 Salisbury Steak and Potatoes
Add small potatoes to the slow cooker alongside the mushrooms and onions for an easy one-pot meal.
What to Serve With
Creamy mashed potatoes are one of the best pairings because they absorb the rich mushroom gravy beautifully.
Buttery egg noodles are another excellent option and make the dish especially comforting.
For a lighter side, serve the Salisbury steaks with steamed green beans, roasted broccoli, peas, or a crisp garden salad.
Dinner rolls or crusty bread are also perfect for soaking up the extra gravy.
Make-Ahead Instructions
The Salisbury steak patties can be shaped up to 24 hours ahead.
Place the uncooked patties in an airtight container and refrigerate until you are ready to cook.
You can also prepare the onions and mushrooms ahead of time and store them separately in the refrigerator.
For the best results, keep raw ingredients properly refrigerated until cooking.
Storage
Allow leftovers to cool before transferring them to airtight containers.
Refrigerate the Salisbury steak and gravy for up to 3–4 days.
Store the steaks together with some gravy to help maintain their moisture.
Reheating
Reheat individual portions in the microwave in short intervals, stirring the gravy between intervals.
For larger portions, place the steaks and gravy in a covered skillet over low heat.
Add a splash of beef broth if the gravy has become too thick during refrigeration.
Heat until the food is thoroughly hot throughout.
Freezing
Salisbury steak freezes well with its mushroom gravy.
Place cooled steaks and gravy in freezer-safe containers, leaving a little space for expansion.
Freeze for up to 3 months for the best quality.
Thaw overnight in the refrigerator before reheating gently on the stovetop or in the microwave.
Common Mistakes to Avoid
Overmixing the beef: Mix only until the ingredients are combined to keep the patties tender.
Skipping the liquid: The broth is essential for creating the flavorful gravy and maintaining moisture during slow cooking.
Adding too much salt: Gravy mix and beef broth can already contain significant salt, so taste before adding more.
Using a very thin gravy: If you prefer a thick restaurant-style gravy, use the cornstarch slurry near the end of cooking.
Opening the slow cooker repeatedly: Each time the lid is removed, heat escapes and cooking can take longer.
Overcooking the patties: Once the steaks are cooked through and tender, avoid leaving them on heat unnecessarily.
