Ingredients You’ll Need
Getting started on this Easy Slow Cooker Salisbury Steak Meatballs Recipe means gathering a handful of simple, everyday ingredients that come together beautifully. Each item plays a key role, from the ground beef delivering rich protein and texture, to the mushrooms and onions adding earthiness and depth to the sauce. The pantry staples like Worcestershire sauce and Dijon mustard sneak in layers of flavor that elevate this dish beyond ordinary comfort food.
- 2 lbs ground beef: The star protein that forms tender, juicy meatballs with just the right amount of fat for flavor and moisture.
- ½ cup breadcrumbs: Helps bind the meatballs together and keeps them tender rather than dense.
- ¼ cup milk: Adds moisture to the mixture, making meatballs delectably soft.
- 1 large egg: Acts as a natural binder holding all the ingredients together.
- 1 small onion, finely chopped: Provides a subtle sweetness and savory base within the meatballs.
- 2 cloves garlic, minced: Gives a fragrant boost and hints of warmth to every bite.
- 1 tbsp Worcestershire sauce: Imparts tangy, umami-rich depth that’s crucial for authentic Salisbury steak flavor.
- 1 tsp salt: Enhances all the flavors harmoniously.
- ½ tsp black pepper: Adds a gentle kick without overpowering the palate.
- 1 tbsp olive oil: Used to brown the meatballs, sealing in juices and developing a caramelized crust.
- 2 cups beef broth: The liquid gold that forms the base of the luscious gravy.
- 1 cup sliced mushrooms: Bring earthiness and texture to the sauce, balancing the richness of the meat.
- 1 small onion, sliced: Adds sweetness and body to the silky mushroom sauce.
- ¼ cup all-purpose flour: Thickens the gravy to the perfect consistency.
- 2 tbsp tomato paste: Intensifies the savoriness and adds a subtle tang.
- 1 tbsp Dijon mustard: Provides a gentle piquancy that lifts the sauce’s flavor profile.
- ½ tsp dried thyme: Offers a fragrant herbaceous note rounding out the dish beautifully.
How to Make Easy Slow Cooker Salisbury Steak Meatballs Recipe
Step 1: Prepare the Meatballs
Start by combining the ground beef, breadcrumbs, milk, egg, finely chopped onion, minced garlic, Worcestershire sauce, salt, and pepper in a large bowl. Mix everything gently but thoroughly so all the flavors blend well without overworking the meat, which could make the meatballs tough. Once everything is combined, shape the mixture into 1-inch meatballs—this size cooks evenly and stays juicy.
Step 2: Brown the Meatballs
To get that delicious caramelized flavor, heat olive oil in a skillet over medium heat. Carefully brown the meatballs on all sides, which should take just a few minutes. Browning locks in flavor and texture, giving the final dish a wonderful depth. Don’t worry about cooking the meatballs all the way through here; they will finish cooking in the slow cooker.
Step 3: Prepare the Sauce
Using the same skillet, toss in the sliced onions and mushrooms and sauté them until they become soft and fragrant. This step releases their natural sweetness and deepens the flavor of your sauce. Next, sprinkle the flour over the veggies and cook for another minute, which will help thicken the sauce later. Gradually stir in the beef broth, allowing the sauce to thicken while stirring continuously. Finish it off by mixing in tomato paste, Dijon mustard, and dried thyme—these add layers of savory, slightly tangy complexity that make the sauce truly irresistible.
Step 4: Slow Cook to Perfection
Transfer the browned meatballs to your slow cooker, then pour the rich mushroom sauce evenly on top. Cover and cook on low for 6 to 8 hours, or on high for 3 to 4 hours. This low, slow simmer lets the meatballs absorb the savory gravy flavor and become incredibly tender. The sauce will thicken even more, coating the meatballs with luscious goodness that will have everyone reaching for seconds.
How to Serve Easy Slow Cooker Salisbury Steak Meatballs Recipe

Garnishes
A sprinkle of freshly chopped parsley or thyme leaves on top adds a beautiful pop of color and a fresh herbal note that brightens the rich flavors. For those who love a little extra tang, a light drizzle of sour cream or a dollop of creamy horseradish sauce makes a delightful addition, complementing the savory mushroom gravy perfectly.
Side Dishes
These meatballs pair wonderfully with classic mashed potatoes—creamy, buttery, and perfect for soaking up every bit of that luscious sauce. For a lighter option, steamed green beans or roasted carrots add a sweet contrast and lovely crunch. And if you’re feeling carb-happy, buttery egg noodles or toasted sandwich buns turn this into a hearty, satisfying feast.
Creative Ways to Present
Try serving the Salisbury steak meatballs over a bed of creamy polenta for an Italian twist or scoop them onto soft slider buns with a bit of extra sauce for a crowd-pleasing appetizer. For an elegant dinner party, arrange the meatballs individually on small plates with a drizzle of sauce around them and a garnish of microgreens for a restaurant-quality presentation right at home.
Make Ahead and Storage
Storing Leftovers
Once cooled, store the leftover meatballs and sauce in an airtight container in the refrigerator. They’ll keep well for up to 3 to 4 days and taste just as comforting on reheating. The flavors actually deepen after a day, making your next meal just as satisfying.
Freezing
This Easy Slow Cooker Salisbury Steak Meatballs Recipe freezes beautifully, making it a fantastic make-ahead option. Place cooled meatballs and some sauce in a freezer-safe container or zip-top bag and freeze for up to 3 months. When you’re ready, thaw overnight in the fridge for best results.
Reheating
To reheat, warm the meatballs gently in a covered skillet or microwave until piping hot. If needed, add a splash of broth or water to loosen the sauce and restore its silky texture. Slow warming helps maintain the meatballs’ tenderness without drying them out.
FAQs
Can I use ground turkey or chicken instead of beef?
Absolutely! Ground turkey or chicken can be a lighter alternative, though the flavor and texture will be a bit different. You might want to add a bit more seasoning or fat (like olive oil) to keep the meatballs moist.
Do I have to brown the meatballs before slow cooking?
Browning adds flavor and texture by creating a tasty crust, but if you’re short on time, you can skip this step and cook them directly in the slow cooker. Just know the flavor may be a little milder.
Can I make the sauce without mushrooms?
Yes! If mushrooms aren’t your thing, you can omit them. The sauce will still be rich and flavorful thanks to the beef broth, tomato paste, and Dijon mustard.
What’s the best side dish for this recipe?
Mashed potatoes are classic and perfect for soaking up the mushroom gravy, but creamy polenta, buttered noodles, or steamed veggies are all excellent choices based on your preference.
How thick should the sauce be when serving?
The sauce should be thick enough to coat the meatballs nicely without being too runny. If it needs thickening after cooking, you can simmer it on the stove for a few minutes with a little extra flour slurry.

Sauce
- 2 cups beef broth
- 1 cup sliced mushrooms

- ¼ cup all-purpose flour
- 2 tbsp tomato paste
- 1 tbsp Dijon mustard
- ½ tsp dried thyme
Instructions
- Prepare Meatballs: In a large mixing bowl, combine ground beef, breadcrumbs, milk, egg, finely chopped onion, minced garlic, Worcestershire sauce, salt, and black pepper. Mix gently until all ingredients are well incorporated. Shape the mixture into 1-inch meatballs evenly sized.
- Brown Meatballs: Heat olive oil in a skillet over medium heat. Add the meatballs and brown them on all sides, taking care not to cook them through completely. This step seals in juices and adds flavor. Once browned, transfer the meatballs to the slow cooker.
- Prepare Sauce: In the same skillet, sauté sliced onions and mushrooms until they become soft and fragrant.

Gradually whisk in the beef broth, ensuring no lumps form, and cook until the sauce begins to thicken. Stir in tomato paste, Dijon mustard, and dried thyme to enrich the flavor.
