Ingredients You’ll Need

The beauty of this recipe lies in its straightforward, pantry-friendly ingredients that work together to create a dish full of flavor, texture, and heart. Each component is carefully chosen to make the meatballs juicy and the gravy luxuriously creamy.

Ground beef (1 1/2 pounds): Provides the rich, meaty base for soft, juicy meatballs packed with flavor.
Breadcrumbs (1/2 cup): These help keep the meatballs tender and give them structure without drying out.
Egg (1 large): Acts as a binder to hold the meatballs together perfectly, preventing them from falling apart.
Milk (1/4 cup): Adds moisture and keeps the texture soft and delicate inside.
Finely chopped onion (1/4 cup): Brings subtle sweetness and aromatic depth to the meatballs.
Worcestershire sauce (1 tablespoon, plus 1 tbsp for gravy): Infuses savory and slightly tangy notes that elevate the entire dish.
Garlic powder (1 teaspoon) & onion powder (1/2 teaspoon): These spices enhance the meat’s natural flavor and add a mild punch.
Salt and pepper: Essential seasonings that balance and highlight every ingredient.
Beef broth (2 cups): Forms the hearty base of the gravy, enriching it with a deep meaty flavor.
Cream of mushroom soup (10.5 ounces): Creates the velvety texture and classic taste of Salisbury steak gravy.
Ketchup (1 tablespoon): Adds a touch of sweetness and acidity that rounds out the gravy beautifully.
Cornstarch mixed with water (optional): This optional slurry gives you control over the gravy’s thickness to suit your preference.
Sliced mushrooms (1 cup, optional): For extra earthy flavor and texture in the gravy.

How to Make Slow Cooker Salisbury Steak Meatballs Recipe

Step 1: Prepare the Meatball Mixture

In a large bowl, gather your ground beef, breadcrumbs, egg, milk, finely chopped onion, Worcestershire sauce, garlic powder, onion powder, salt, and pepper. Mix these ingredients gently, just until combined—overmixing can make the meatballs tough, so a light hand works best. Once mixed, shape the mixture into meatballs about 1 to 1 1/2 inches wide, making sure they’re evenly sized so they cook uniformly.

Step 2: Arrange Meatballs in the Slow Cooker

Place the formed meatballs carefully into the bottom of a 6-quart slow cooker in a single, cozy layer. This helps them cook evenly and soak up all those luscious flavors from the gravy.

Step 3: Whisk Together the Gravy

In a separate bowl, combine the beef broth, cream of mushroom soup, Worcestershire sauce, and ketchup. Give it a thorough whisk until you have a smooth, creamy mixture. If you’re using mushrooms, now is the time to toss them in as well. Pour this rich gravy evenly over the meatballs, making sure every bite will be soaked with that delicious sauce.

Step 4: Slow Cook to Perfection

Cover the slow cooker and cook on low for 4 to 5 hours, or on high for 2 to 3 hours, until the meatballs are cooked through and tender. If you prefer a thicker gravy, stir in the cornstarch slurry during the last 30 minutes of cooking to let it thicken beautifully.

How to Serve Slow Cooker Salisbury Steak Meatballs Recipe

Garnishes

A sprinkle of fresh chopped parsley or chives adds a lovely pop of color and fresh brightness to the rich, savory meatballs and gravy. For a touch of indulgence, a small dollop of sour cream on top adds creaminess and tang that complements the dish wonderfully.

Side Dishes

These meatballs are incredibly versatile when it comes to sides. Classic creamy mashed potatoes soak up the gravy perfectly, while buttered egg noodles offer a comfort-food vibe that can’t be beat. For a lighter alternative, fluffy white rice or even steamed green beans make excellent companions to this hearty main course.

Creative Ways to Present

For a vibrant twist, serve the meatballs over mashed cauliflower or alongside roasted root vegetables to add a splash of color and texture. You can also transform them into a hearty meatball sub with a toasted bun and melted cheese for a fun weeknight dinner variation that everyone will love.

Make Ahead and Storage

Storing Leftovers

Once cooled, place any leftover meatballs and gravy into an airtight container and store in the refrigerator for up to 3 days. The flavors actually deepen overnight, making your leftovers even better the next day.

Freezing

This Slow Cooker Salisbury Steak Meatballs Recipe freezes wonderfully. Transfer cooled meatballs and gravy into a freezer-safe container or zip-top bag, removing as much air as possible. They’ll keep well for up to 3 months. When ready to enjoy, thaw overnight in the refrigerator before reheating.

Reheating

Reheat gently on the stovetop over low heat to prevent the meatballs from drying out, stirring occasionally until warmed through. You can also microwave in a covered dish, but be careful to use shorter intervals and stir between to keep the gravy smooth and the meatballs tender.

FAQs

Can I use pre-cooked or frozen meatballs in this recipe?

Absolutely! Using pre-cooked or frozen meatballs is a great shortcut. Just reduce the cooking time accordingly—generally about half—since you’re mainly warming them through and letting them soak in the gravy flavors.

Is it necessary to brown the meatballs before slow cooking?

Browning the meatballs in a skillet is optional but highly recommended. It adds a beautiful caramelized crust and extra depth of flavor. However, if you’re short on time, you can skip this step and place the raw meatballs directly into the slow cooker.

Can I make this recipe in an Instant Pot?

Yes, you can adapt the recipe for an Instant Pot by using the sauté function to brown the meatballs, then pressure cooking on high for about 10 minutes. Just be sure to use the sauté mode to thicken the gravy afterward if needed.

How do I make the gravy thicker if I prefer a richer sauce?

Mix 1 tablespoon of cornstarch with 1 tablespoon of cold water to create a slurry. Stir this into the slow cooker during the last 30 minutes of cooking and continue to cook until the gravy reaches your desired thickness.

Can I customize the recipe to be gluten-free?

Definitely! Substitute regular breadcrumbs for gluten-free breadcrumbs and use a gluten-free cream of mushroom soup. Also, double-check that your Worcestershire sauce is gluten-free to keep the dish safe for gluten-sensitive diets.
