What You’ll Need
- 2 pounds frozen fully cooked beef meatballs
- 2 cups beef broth
- 1 packet brown gravy mix
- 1 packet onion soup mix
- 1 tablespoon Worcestershire sauce
- 1 tablespoon ketchup
- 1 teaspoon garlic powder
- 1/2 teaspoon black pepper
- 8 ounces sliced mushrooms
- 1 small onion, diced
- 2 tablespoons cornstarch
- 2 tablespoons cold water
- Fresh parsley, chopped, for serving

Recipe and Instructions
Step 1: Add the Meatballs
Place 2 pounds frozen fully cooked beef meatballs into the black oval crockpot. Spread them out in an even layer.

Step 2: Mix the Gravy
In a bowl, whisk together 2 cups beef broth, 1 packet brown gravy mix, 1 packet onion soup mix, 1 tablespoon Worcestershire sauce, 1 tablespoon ketchup, 1 teaspoon garlic powder, and 1/2 teaspoon black pepper until smooth.

Step 3: Add Onion and Mushrooms
Sprinkle 1 small diced onion and 8 ounces sliced mushrooms over the frozen meatballs in the black oval crockpot.

Step 4: Pour in the Gravy
Pour the smooth gravy mixture over the meatballs, diced onion, and sliced mushrooms. Make sure most of the meatballs are coated.

Step 5: Slow Cook
Cover and cook on low for 4 hours or high for 2 hours, until the meatballs are hot and the onions are soft.
Step 6: Thicken the Gravy
In a small bowl, stir 2 tablespoons cornstarch with 2 tablespoons cold water until smooth. Pour it into the crockpot and stir gently. Cover and cook for 15 more minutes, until the gravy thickens.

Step 7: Serve
Spoon the Salisbury steak meatballs into a round bowl and sprinkle with chopped fresh parsley. Serve warm with mashed potatoes, rice, noodles, or vegetables.

Pro Tips
- Use fully cooked frozen meatballs so they heat safely and stay firm.
- Do not skip the cornstarch slurry. It makes the gravy thick and silky.
- Stir gently near the end so the meatballs do not break apart.
- For extra flavor, add a small splash more Worcestershire sauce before serving.
- Taste before adding salt. The gravy mix and onion soup mix can already be salty.
Tools You’ll Need
- Black oval crockpot
- Mixing bowl
- Small bowl
- Whisk
- Measuring cups
- Measuring spoons
- Large spoon
Substitutions and Variations
- Use turkey meatballs instead of beef meatballs.
- Use chicken broth if that is what you have, but beef broth gives deeper flavor.
- Add a splash of heavy cream at the end for a creamier gravy.
- Use canned mushrooms if you do not have fresh mushrooms.
- Add a pinch of red pepper flakes for a little heat.
Make Ahead Tips
- You can mix the gravy the night before and keep it in the fridge.
- You can also dice the onion ahead of time and store it in a sealed container.
- Do not add the cornstarch slurry until the end of cooking.
Why This Recipe Works Quick Science
- The crockpot heats the meatballs slowly, so they stay tender.
- The gravy mix and onion soup mix add salt, onion flavor, and body.
- Cornstarch thickens the liquid when it gets hot. Mixing it with cold water first keeps it from clumping.
- Mushrooms add a deep, savory taste that makes the gravy richer.
Common Mistakes
- Adding cornstarch straight into hot gravy can make lumps.
- Cooking too long on high may make the meatballs too soft.
- Using raw meatballs changes the cook time and can make the gravy greasy.
- Adding too much salt early can make the dish too salty.
What to Serve With
- Mashed potatoes are the classic choice.
- Egg noodles are great with the thick gravy.
- White rice keeps it simple.
- Roasted green beans or broccoli add a fresh side.
- Buttered rolls are perfect for scooping up extra gravy.
