Ingredients

For the Meatballs:

• 1 pound ground beef

• 1/2 cup breadcrumbs

• 1/4 cup grated Parmesan cheese

• 1/4 cup chopped parsley (fresh preferred)

• 1 egg

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• Salt and pepper, to taste

• 1 tablespoon olive oil (for browning)

For the Gravy:

• 1 cup beef broth

• 1 cup sliced mushrooms (button or cremini)

• 1 packet onion soup mix

• 1 tablespoon Worcestershire sauce

• 1 tablespoon cornstarch (optional, for thickening)

Preparation

Step 1: Prepare the Meatball Mixture

In a large mixing bowl, combine the ground beef, breadcrumbs, grated Parmesan, chopped parsley, egg, garlic powder, onion powder, salt, and pepper. Use your hands or a wooden spoon to gently mix until all ingredients are evenly incorporated. Avoid overmixing, which can make the meatballs tough.

Step 2: Shape the Meatballs

Using your hands or a small scoop, form the mixture into uniform 1 to 1.5-inch balls. You should get about 18–20 meatballs from one pound of beef.

Step 3: Brown the Meatballs

Heat 1 tablespoon of olive oil in a skillet over medium heat. Add the meatballs in batches and sear them for about 2–3 minutes on each side, until browned. You don’t need to cook them through—just enough to get that rich flavor and help them hold their shape during slow cooking.

Step 4: Prepare the Slow Cooker Gravy

In the bottom of your slow cooker, whisk together the beef broth, onion soup mix, Worcestershire sauce, and cornstarch (if using). Stir in the sliced mushrooms. This mixture will thicken and become the delicious gravy that envelops the meatballs.

Step 5: Add Meatballs to the Slow Cooker

Carefully place the browned meatballs into the slow cooker, nestling them into the gravy and mushrooms. Spoon a bit of gravy over the top so they’re fully coated.

Step 6: Slow Cook to Perfection

Cover and cook on LOW for 4–5 hours or HIGH for 2–3 hours, until the meatballs are cooked through (internal temperature of 160°F) and the gravy has thickened. Give it a gentle stir halfway through if desired.

Step 7: Serve and Enjoy

Serve the meatballs hot, spooning generous amounts of gravy and mushrooms over your favorite sides like mashed potatoes, egg noodles, or rice. Garnish with extra parsley for a fresh finish.

Variation

• Turkey or Chicken Version: Use ground turkey or chicken for a lighter version. Add a splash of milk to keep them moist.

• Cheese-Stuffed Meatballs: Place a small cube of mozzarella inside each meatball for a cheesy surprise.

• Creamy Mushroom Gravy: Add 1/4 cup of heavy cream during the last 30 minutes of cooking for an ultra-creamy sauce.

• Veggie-Loaded: Add diced carrots, celery, or peas to the gravy mixture to make it heartier and more nutritious.

• Gluten-Free: Substitute gluten-free breadcrumbs and ensure your onion soup mix is gluten-free.

Cooking Note

Browning the meatballs before slow cooking is optional but highly recommended. It develops a deeper flavor and helps maintain their structure in the sauce. If you’re in a hurry, you can skip this step and add the raw meatballs directly to the slow cooker—but expect a slightly softer texture.

Serving Suggestions

• Mashed Potatoes: Creamy and buttery, they’re the perfect base to catch all that savory gravy.

• Egg Noodles: The traditional pairing for Salisbury-style dishes.

• White or Brown Rice: A neutral backdrop that soaks up the sauce.

• Buttered Dinner Rolls: Ideal for scooping up extra gravy.

• Green Beans or Steamed Broccoli: Add a crisp, fresh contrast to the rich meatballs.

Tips

• Use Fresh Herbs: While dried parsley can work in a pinch, fresh parsley brings brighter flavor.

• Don’t Overmix: Mix the meatball mixture just until combined for tender results.

• Prep Ahead: Form and brown the meatballs the night before for a super quick morning assembly.

• Double the Batch: Freeze half the meatballs (uncooked or cooked) for an easy future meal.

• Gravy Too Thin?: Stir in a cornstarch slurry (1 tablespoon cornstarch + 2 tablespoons cold water) and cook on HIGH for an additional 15 minutes.

Prep Time: 15 minutes

Cooking Time: 4–5 hours on LOW or 2–3 hours on HIGH

Total Time: Approximately 4 hours 15 minutes to 5 hours 15 minutes

FAQs

Can I make this without a slow cooker?

Yes! You can make these in a Dutch oven or large skillet. Prepare the gravy in the same pan you browned the meatballs, then return them to the pan, cover, and simmer on low for about 25–30 minutes.

Can I freeze Salisbury Steak Meatballs?

Absolutely. Freeze cooked meatballs with gravy in an airtight container for up to 3 months. Thaw in the fridge overnight and reheat on the stovetop or microwave.

What if I don’t have onion soup mix?

You can substitute with a mixture of 2 tablespoons dried minced onion, 1/2 teaspoon onion powder, a pinch of garlic powder, and a bouillon cube for a similar flavor.

How do I thicken the gravy?

If your gravy is too thin, mix 1 tablespoon of cornstarch with 2 tablespoons of cold water and stir it into the sauce. Let it cook uncovered on HIGH for 15–20 minutes until thickened.

What’s the best mushroom for this recipe?

Cremini or white button mushrooms work beautifully. For a more intense, earthy flavor, try a mix of wild mushrooms.
