Ingredients

For the Salisbury Steaks:

• 1 ½ lbs (680 g) lean ground beef (80/20 recommended)
• ½ cup (60 g) plain breadcrumbs
• 1 large egg, lightly beaten
• 1 tsp onion powder
• ½ tsp garlic powder
• 1 tsp Worcestershire sauce
• ½ tsp salt
• ¼ tsp black pepper
• 1 tbsp (15 ml) olive oil (for optional searing)

For the Gravy:

• 1 tbsp (15 ml) olive oil
• 1 large yellow onion, chopped
• 8 oz (225 g) cremini or button mushrooms, sliced (optional)
• 2 cans (10.5 oz or 298 g each) cream of mushroom soup
• 1 ½ cups (360 ml) beef broth
• 2 tbsp (30 ml) ketchup
• 1 tbsp (15 ml) Dijon mustard
• 1 tbsp (15 ml) Worcestershire sauce
• ½ tsp black pepper
• ¼ cup (60 ml) water + 2 tbsp (30 g) cornstarch (for slurry)

Ingredient Notes

• Ground Beef: Using 80/20 lean ground beef provides enough fat for flavor without being overly greasy. You can use leaner beef, but the patties might be slightly less moist.
• Breadcrumbs: Plain breadcrumbs help bind the patties and add tenderness. Panko breadcrumbs also work for a slightly lighter texture.
• Cream of Mushroom Soup: This is a classic shortcut for a creamy, flavorful gravy in slow cooker recipes. For a homemade alternative, you can make a roux-based mushroom gravy.
• Mushrooms: While optional, mushrooms add an earthy depth that is traditional to Salisbury steak. Cremini (baby bella) mushrooms offer the best flavor.
• Cornstarch Slurry: This is crucial for thickening the gravy at the end. Make sure to whisk the cornstarch thoroughly with cold water to avoid lumps.

Equipment You’ll Need

• 6-quart or larger slow cooker
• Large mixing bowl
• Large skillet (optional, for searing patties)
• Whisk

How to Make Slow Cooker Salisbury Steaks

Follow these simple steps to create perfectly tender and flavorful Salisbury steaks in your slow cooker.

Step 1: Prepare the Salisbury Steak Patties

1. In a large mixing bowl, combine the ground beef, breadcrumbs, beaten egg, onion powder, garlic powder, 1 teaspoon Worcestershire sauce, salt, and pepper.
2. Gently mix until just combined, being careful not to overmix, as this can lead to tough patties.
3. Divide the mixture into 6-8 oval-shaped patties, about ¾-inch (2 cm) thick.

Step 2: (Optional) Sear the Patties

1. Heat 1 tablespoon of olive oil in a large skillet over medium-high heat.
2. Sear the patties for 2-3 minutes per side, just until browned. This step adds extra flavor and helps the patties hold their shape, but it’s optional if you’re short on time.
3. Remove the seared patties and set aside.

Step 3: Assemble the Slow Cooker

1. Lightly grease the bottom of your slow cooker insert.
2. Spread the chopped onion and sliced mushrooms (if using) evenly over the bottom of the slow cooker.
3. Place the seared (or unseared) Salisbury steak patties in a single layer over the vegetables.

Step 4: Prepare and Add the Gravy

1. In a separate bowl, whisk together the cream of mushroom soup, beef broth, ketchup, Dijon mustard, 1 tablespoon Worcestershire sauce, and black pepper until smooth.
2. Pour the gravy mixture evenly over the Salisbury steak patties in the slow cooker, ensuring they are mostly covered.

Step 5: Cook

1. Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, until the patties are tender and cooked through.

Step 6: Thicken the Gravy and Serve

1. Once the cooking time is complete, carefully remove the Salisbury steak patties to a plate.
2. In a small bowl, whisk together the cold water and cornstarch to create a smooth slurry.
3. Pour the cornstarch slurry into the gravy in the slow cooker, whisking continuously.
4. Increase the slow cooker setting to high (if not already there) or use the ‘stew’ setting if available, and cook for another 15-30 minutes, or until the gravy has thickened to your desired consistency.
5. Return the Salisbury steak patties to the thickened gravy just before serving to warm through.

Pro Tips for the Best Results

• Don’t Overmix the Meat: Overmixing ground beef can result in tough, dense patties. Mix just until ingredients are combined.
• Sear for Flavor: While optional, searing the patties before slow cooking adds a delicious depth of flavor and a nice crust that holds up well in the gravy.
• Use Quality Beef Broth: A good quality beef broth will significantly enhance the flavor of your gravy.
• Adjust Gravy Thickness: If you prefer a thinner gravy, use less cornstarch slurry. For a thicker gravy, you can add a bit more, mixed with water first.
• Season to Taste: Always taste your gravy before thickening and adjust seasonings as needed. A pinch more salt, pepper, or Worcestershire can make a big difference.

Common Mistakes to Avoid

• Overworking the Beef: As mentioned, this makes patties tough. Handle the meat as little as possible.
• Skipping the Onions and Mushrooms: These vegetables add essential flavor and texture to the gravy. Don’t omit them unless absolutely necessary.
• Adding Cornstarch Directly to Hot Liquid: Always mix cornstarch with cold water first to create a slurry. Adding it directly to hot liquid will create lumps.
• Not Adjusting Gravy Consistency: Don’t settle for a watery gravy. Take the extra step to thicken it to your liking with the cornstarch slurry.
• Lifting the Lid Too Often: Each time you lift the slow cooker lid, you release heat and extend the cooking time. Try to resist peeking!

Variations & Substitutions

• Ground Meat: While beef is traditional, you can try ground turkey or a mix of ground beef and pork for a different flavor profile.
• Homemade Gravy: Instead of cream of mushroom soup, you can make a scratch-made brown gravy. Start with a roux of butter and flour, then whisk in beef broth and seasonings.
• Added Vegetables: Feel free to add other vegetables to the slow cooker alongside the onions and mushrooms, such as sliced bell peppers or carrots for extra nutrition and flavor.
• Spice It Up: Add a pinch of red pepper flakes for a subtle kick, or a dash of smoked paprika for a smoky undertone.
• Onion Soup Mix: For an even simpler gravy, you can substitute the cream of mushroom soup and some of the seasonings with a packet of onion soup mix.

Serving Suggestions

Slow Cooker Salisbury Steaks are a complete meal in themselves, but they truly shine when served with classic accompaniments that can soak up all that delicious gravy:

• Creamy Mashed Potatoes: The ultimate pairing! The rich gravy is perfect over fluffy mashed potatoes.
• Egg Noodles: Wide egg noodles are another fantastic choice, absorbing the savory sauce beautifully.
• White Rice: A simple bed of white rice is excellent for soaking up all the flavors.
• Steamed Green Beans or Asparagus: A fresh, crisp green vegetable provides a nice contrast to the rich gravy.
• Corn on the Cob or Creamed Corn: Adds a touch of sweetness that complements the savory dish.
• Crusty Bread: Don’t forget some crusty bread to sop up any leftover gravy!

Storage & Reheating

• Refrigerator: Leftover Salisbury steaks and gravy can be stored in an airtight container in the refrigerator for up to 3-4 days.
• Freezer: This dish freezes exceptionally well. Allow to cool completely, then transfer to a freezer-safe container or heavy-duty freezer bags. It will keep for 2-3 months. Thaw overnight in the refrigerator before reheating.
• Reheating: For best results, reheat gently on the stovetop over medium-low heat, stirring occasionally, until warmed through. You may need to add a splash of beef broth or water if the gravy has thickened too much. Alternatively, reheat in the microwave in individual portions, stirring halfway through.

FAQ

Can I use ground turkey instead of ground beef?

Yes, you can use ground turkey, but for the best flavor and moisture, use ground turkey with a higher fat content (e.g., 85/15). The patties might be a bit drier than those made with ground beef.

Do I have to sear the Salisbury steak patties?

Searing is optional but highly recommended. It adds a delicious browned crust, locks in flavor, and helps the patties maintain their shape during slow cooking. If you’re pressed for time, you can skip this step, but the flavor depth may be slightly less.

Can I make this recipe without cream of mushroom soup?

Yes, you can create a homemade gravy. You’ll need to make a roux with butter and flour, then whisk in beef broth, seasonings, and possibly some heavy cream or milk for richness. This will add a bit more prep time.

How can I make the gravy thicker or thinner?

To thicken the gravy, add more cornstarch slurry (1 tablespoon cornstarch mixed with 2 tablespoons cold water) and cook on high for a bit longer. To thin it out, simply stir in a splash more beef broth or water until it reaches your desired consistency.

What if my Salisbury steaks come out tough?

The most common reason for tough patties is overmixing the ground beef mixture. Gently combine the ingredients until they are just incorporated. Using ground beef with a higher fat content (like 80/20) also helps keep them tender.

Can I add other vegetables to the slow cooker?

Absolutely! Sliced carrots, bell peppers, or even frozen peas (added during the last 30 minutes of cooking) would be delicious additions to the gravy.
