Ingredients for the Sauce and Meatballs

• 1 bag (26 oz) frozen meatballs (about 30-35 meatballs)
• 2 cups reduced-sodium beef broth (see notes)
• 1 packet brown gravy mix
• 1 packet onion soup mix
• 2 tablespoons ketchup
• 1 tablespoon Worcestershire sauce
• 2 tablespoons cornstarch (see notes)
• 2 tablespoons cold water

How to Make It in the Slow Cooker

1. Spray the slow cooker insert with nonstick cooking spray.
2. Add frozen meatballs (about 26 oz / 30–35 meatballs) to the slow cooker.
3. Whisk together beef broth, brown gravy mix, onion soup mix, ketchup, and Worcestershire sauce until smooth.
4. Pour the sauce over the meatballs and gently stir to coat.
5. Cover and cook on LOW for 5 to 6 hours, keeping the lid closed.
6. Whisk cornstarch and cold water in a small bowl until smooth to make a slurry.

7. Stir the cornstarch slurry into the slow cooker and cook an additional 10 minutes, until the gravy thickens.

Tips for Tender, Well-Seasoned Meatballs

• Keep those meatballs frozen—this recipe is designed for frozen, not thawed, meatballs. Use one 26 oz bag (about 30–35 meatballs).
• Spray your slow cooker insert with nonstick spray to prevent sticking and make clean up easier.
• Choose reduced-sodium beef broth if you like your meal a bit less salty. The gravy and onion soup packets add salt, so balancing is key.
• Keep the lid closed during cooking to lock in moisture and make sure your meatballs stay juicy. Set cook time at LOW for 5–6 hours, but check around 4½–5 hours if your slow cooker tends to run hot.
• If you want thicker gravy, stir in 2 tablespoons cornstarch mixed with 2 tablespoons cold water towards the end and cook for 10 more minutes. For thinner but still perfect gravy, use 1 tablespoon each.
• Mix the cornstarch slurry really well before adding to avoid lumps, and stir gently once in the crockpot so it distributes evenly.
• If the gravy feels too salty at the end, try serving it over a neutral base like mashed potatoes, noodles, or rice, and use reduced-sodium mixes or broth next time.
• Store leftovers in an airtight container in the fridge for up to 4 days. Reheat gently on the stovetop or microwave, stirring occasionally to keep the gravy nice and smooth.
• Add a sprinkle of fresh chopped parsley at the end for a pop of color and fresh flavor—plus, it looks pretty on the plate!

Serving Ideas and Simple Swaps

I love serving these slow cooker salisbury steak meatballs over fluffy white rice or buttery egg noodles, or even over an easy one-pot veggie pasta if you want extra veg. Either way, they soak up that rich gravy so well. Don’t forget a sprinkle of fresh chopped parsley for that finishing touch. For something fresh on the side, add a bowl of Crunchy Ranch Cucumber Chips. Craving a different twist? Try turkey meatballs for a lighter option, or Italian-style for a little extra herbiness.

Storing and Reheating Leftovers

Keep any leftovers in a sealed container in your fridge for up to four days. To reheat, warm the meatballs and gravy gently on the stovetop in a saucepan or use the microwave. Stir every so often to keep that gravy smooth and the meatballs tender. For a quick next-day meal, spoon the reheated meatballs and gravy over Cheesy Crock Pot Rotini.

Common Questions and Answers

What Type of Frozen Meatballs Do I Use?

You can pick any frozen meatballs you like! Just grab about 26 ounces—usually around 25 to 30 meatballs. I stick with classic homestyle, but turkey, Italian, or another variety works great. My go-to is Costco’s frozen meatballs, and I just count out about 30.

Do I Need To Thaw The Meatballs Before Cooking Them?

Absolutely not! Just dump those frozen meatballs right into your slow cooker. It saves time and they cook evenly.

Can I Use Homemade Meatballs?

Yes! If you prefer homemade, just make sure your meatballs are about the same size as frozen ones—roughly 30 meatballs—to keep the cooking times consistent.

What Is The Cornstarch Slurry For?

The cornstarch slurry is the secret to that perfect, rich gravy. It thickens the sauce after the slow cooker is done so your gravy isn’t watery. If you prefer a thinner sauce, you can skip the slurry and serve meatballs with the natural sauce from cooking.
