Instructions
- Prepare the Meatball Mixture: In a large bowl, combine the ground beef, egg, panko breadcrumbs, milk, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Gently mix with your hands until just combined. Avoid overmixing, as this can make the meatballs tough.
- Form the Meatballs: Roll the meat mixture into meatballs, about 1-1.5 inches in diameter. You should get approximately 24-30 meatballs.
- Brown the Meatballs (Optional): For added flavor and better texture, heat the olive oil in a large skillet over medium-high heat. Brown the meatballs on all sides, working in batches to avoid overcrowding the pan. This step is optional, but it enhances the flavor of the meatballs. Remove the browned meatballs from the skillet and set aside.
- Prepare the Gravy: In the same skillet (if you browned the meatballs) or directly in the slow cooker (if you skipped the browning step), add the sliced onions and cook over medium heat until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant.
- Add Mushrooms and Cream of Mushroom Soup: Add the sliced mushrooms to the skillet (or slow cooker) and cook until they release their moisture and start to brown, about 5-7 minutes. Stir in the cream of mushroom soup and beef broth. Bring to a simmer, scraping up any browned bits from the bottom of the pan.
- Thicken the Gravy (if needed): If you prefer a thicker gravy, whisk together the flour (or cornstarch) and cold water in a small bowl to create a slurry. Gradually add the slurry to the gravy, stirring constantly, until the gravy thickens to your desired consistency. This may not be necessary depending on the thickness of the cream of mushroom soup.
- Assemble in the Slow Cooker: If you browned the meatballs in a skillet, transfer the gravy to the slow cooker. Place the meatballs in the slow cooker, arranging them in a single layer if possible. Pour the gravy over the meatballs, making sure they are mostly submerged.
- Slow Cook: Cover the slow cooker and cook on low for 6-8 hours or on high for 3-4 hours, or until the meatballs are cooked through and tender. Cooking times may vary depending on your slow cooker. The internal temperature of the meatballs should reach 160°F (71°C).
- Serve: Once the meatballs are cooked, garnish with chopped fresh parsley. Serve hot over mashed potatoes, egg noodles, rice, or your favorite side dish.
Cooking Tips and Variations
Here are some tips and variations to help you customize this Slow Cooker Salisbury Steak Meatballs recipe to your liking:
- Preventing Dry Meatballs: To ensure your meatballs stay moist and tender, avoid overmixing the meat mixture. Overmixing can result in tough meatballs. Also, don’t cook the meatballs for too long in the slow cooker. Check for doneness after the minimum cooking time and adjust accordingly.
- Browning for Flavor Depth: While optional, browning the meatballs in a skillet before adding them to the slow cooker adds a significant layer of flavor. The Maillard reaction (browning) creates complex flavors that enhance the overall taste of the dish.
- Adjusting Gravy Thickness: If your gravy is too thin, you can thicken it by adding a cornstarch slurry (1 tablespoon cornstarch mixed with 1 tablespoon cold water) during the last 30 minutes of cooking. Alternatively, if the gravy is too thick, you can thin it out by adding a little more beef broth.
- Adding Vegetables: For a more nutritious and flavorful dish, you can add diced vegetables to the gravy. Onions, carrots, and celery are excellent additions. Sauté them in the skillet before adding the mushrooms.
- Mushroom Variety: Feel free to experiment with different types of mushrooms. Cremini (baby bella) mushrooms and white button mushrooms are commonly used, but you can also try shiitake, oyster, or portobello mushrooms for a more intense flavor.
- Flavor Boosters: For a richer, more complex flavor, add a splash of red wine or Worcestershire sauce to the gravy. A teaspoon of Dijon mustard can also add a tangy note.
- Gluten-Free Option: To make this recipe gluten-free, use gluten-free panko breadcrumbs and a gluten-free thickener, such as cornstarch or arrowroot powder. Ensure that the cream of mushroom soup is also gluten-free.
- Spice it up: Add a pinch of red pepper flakes to the meatball mixture or gravy for a little heat.
- Herb Infusion: Add fresh thyme or rosemary sprigs to the slow cooker during cooking for an aromatic flavor. Remove the sprigs before serving.
Storage and Reheating
Proper storage and reheating are essential to maintain the quality and safety of your leftover Slow Cooker Salisbury Steak Meatballs.

- Tips for Reheating:
- Add a splash of beef broth or water when reheating to prevent the gravy from drying out.
- If the gravy becomes too thick during reheating, add a little more broth or water to thin it out.
- Avoid overheating the meatballs, as this can make them tough.
Frequently Asked Questions
Can I use ground turkey or chicken instead of ground beef?
