Instructions
- In a large bowl, combine the ground beef, breadcrumbs, egg, 1 tablespoon of Worcestershire sauce, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon black pepper, and 1/4 teaspoon salt. Mix gently with your hands until just combined. Be careful not to overmix, as this can lead to tough patties.
- Divide the beef mixture into 8 equal portions and form them into oval-shaped patties, about 1-inch thick.
- Heat the olive oil in a large skillet over medium-high heat. Once hot, carefully place the patties in the skillet, working in batches if necessary to avoid overcrowding. Sear the patties for 3-4 minutes per side, until deeply browned. This step is crucial for developing rich flavor and a good crust. Remove the browned patties from the skillet and set aside.
- If desired, add the sliced fresh mushrooms to the same skillet and sauté for 5-7 minutes until softened and lightly browned. Remove and set aside.
- Place the thinly sliced onions evenly on the bottom of your slow cooker insert.
- Arrange the browned beef patties over the layer of onions in the slow cooker. If you sautéed mushrooms, scatter them over the patties.
- In a separate medium bowl, whisk together the beef broth, condensed cream of mushroom soup, brown gravy mix, the remaining 1 tablespoon of Worcestershire sauce, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/4 teaspoon black pepper, and 1/4 teaspoon salt until smooth and well combined.
- Pour the gravy mixture evenly over the patties and onions in the slow cooker.
- Cover the slow cooker and cook on LOW for 6-8 hours or on HIGH for 3-4 hours, or until the patties are fork-tender and the onions are very soft.
- About 30 minutes before serving, prepare a cornstarch slurry: In a small bowl, whisk together the 2 tablespoons of cornstarch and 1/4 cup of cold water until smooth.
- Uncover the slow cooker and slowly pour the cornstarch slurry into the gravy, stirring constantly until the gravy begins to thicken. Continue to cook for another 20-30 minutes, or until the gravy reaches your desired consistency.
- Taste the gravy and adjust seasonings if necessary.
- Serve hot, garnished with fresh chopped parsley if desired. This dish pairs wonderfully with mashed potatoes, egg noodles, or rice to soak up all that delicious gravy.
Cooking Tips and Variations
For the juiciest patties, resist the urge to overmix the ground beef. Gentle handling ensures a tender texture. Also, using 80/20 ground beef provides enough fat to keep the patties moist and flavorful during the long cooking process. Browning the patties before slow cooking is non-negotiable; this searing step creates a deep, caramelized crust (the Maillard reaction) that adds incredible depth of flavor to the entire dish. Don’t skip it, even if you’re in a hurry!
To enhance the gravy’s flavor even further, after browning the patties, you can deglaze the skillet with a splash of beef broth or even red wine. Scrape up all those delicious browned bits from the bottom of the pan and add them to your slow cooker along with the rest of the gravy mixture. This adds an extra layer of umami that makes a noticeable difference. If you’re a mushroom lover, adding sliced fresh mushrooms directly to the slow cooker with the onions will infuse the gravy with their earthy notes, or you can sauté them briefly with the patties for even more flavor.
For a gluten-free version, ensure your breadcrumbs are gluten-free and check the labels on your brown gravy mix and cream of mushroom soup to confirm they are also gluten-free. You can thicken the gravy with a cornstarch slurry as instructed, as cornstarch is naturally gluten-free. For a richer gravy, consider adding a splash of heavy cream or a tablespoon of butter at the very end of cooking, just before serving. This will give it a silken texture and an even more indulgent taste. If you prefer a lighter sodium content, always opt for low-sodium beef broth and adjust salt to taste.
Experiment with different seasonings in your patties. A pinch of smoked paprika, a dash of dried thyme, or a touch of Dijon mustard can add interesting twists. For a slightly spicier kick, a tiny pinch of cayenne pepper can be incorporated into the gravy. Remember, the beauty of slow cooking is its forgiving nature, allowing flavors to meld and deepen over time, so don’t be afraid to personalize this classic to your taste preferences.
Storage and Reheating
This Slow Cooker Salisbury Steak with Onion Gravy makes for excellent leftovers, often tasting even better the next day as the flavors continue to meld. To store, allow the dish to cool completely to room temperature. Transfer the Salisbury steak and gravy to an airtight container. It can be stored in the refrigerator for up to 3-4 days. For longer storage, this dish freezes beautifully. Place the cooled Salisbury steak and gravy in freezer-safe containers or heavy-duty freezer bags, removing as much air as possible to prevent freezer burn. It can be frozen for up to 2-3 months.
When reheating from the refrigerator, the best method is to gently warm it on the stovetop over medium-low heat. Place the desired portion of Salisbury steak and gravy in a saucepan, adding a splash of beef broth or water if the gravy has thickened too much. Stir occasionally until heated through. You can also reheat individual portions in the microwave; cover the dish and heat in 1-minute intervals, stirring in between, until hot. Be careful not to overheat, as this can dry out the patties.
If reheating from frozen, it’s best to thaw the dish overnight in the refrigerator first. Once thawed, reheat using the stovetop or microwave methods described above. If you’re in a pinch and need to reheat from frozen, you can do so on the stovetop on very low heat, adding a little liquid and stirring frequently to prevent sticking, or use the defrost setting on your microwave before fully reheating. Always ensure the internal temperature reaches 165°F (74°C) for safe consumption.
Frequently Asked Questions
Can I make the patties ahead of time?
Yes, you can definitely prepare the raw patties ahead of time. Form the patties and place them on a parchment-lined baking sheet. Cover tightly with plastic wrap and refrigerate for up to 24 hours. You can also freeze the raw patties for longer storage; flash freeze them on a baking sheet until solid, then transfer to a freezer-safe bag for up to 3 months. Thaw completely in the refrigerator before browning and slow cooking.
What can I serve with Salisbury steak?
Classic pairings for Salisbury steak include creamy mashed potatoes, which are perfect for soaking up every drop of that delicious gravy. Other excellent options are egg noodles, white rice, or even crusty bread. For a balanced meal, consider serving it alongside green beans, steamed broccoli, or a simple side salad. The rich, savory flavors of the steak and gravy are beautifully complemented by lighter, fresh vegetable sides.
My gravy isn’t thick enough, what should I do?
If your gravy isn’t as thick as you’d like after the initial cornstarch slurry, you can easily thicken it further. In a small bowl, whisk together 1 tablespoon of cornstarch with 2 tablespoons of cold water to create another slurry. Slowly whisk this into the simmering gravy in the slow cooker, stirring constantly, and cook for another 15-20 minutes until it reaches your desired consistency. Avoid adding dry cornstarch directly, as it will clump.
Can I use a different type of ground meat?
While ground beef is traditional for Salisbury steak, you can certainly experiment with other ground meats. A mix of ground beef and ground pork can add extra flavor and moisture. Ground turkey or chicken can be used for a leaner option, but be aware that the patties might be less rich and may require a bit more seasoning and perhaps a touch of added fat (like olive oil or butter) to prevent them from drying out during the long cook time. Adjust cooking times as needed if using leaner meats, as they can cook faster.
