Expert Shortcuts and Adjustments

• Coat your slow cooker insert with nonstick spray to make serving and cleaning up a breeze.
• Choose your broth based on flavor and salt preference: full-salt beef broth gives bolder taste after hours of cooking, while reduced-sodium lets you control saltiness better. Always taste before serving and adjust as needed.
• For gravy thickness: whisk 1 tablespoon cornstarch with 1 tablespoon cold water for a thinner, pourable gravy, or double it to 2 tablespoons each for a thicker sauce. Mix well to avoid lumps, then let the gravy thicken for about 10 minutes.
• Stir gently after adding the sauce so the dry gravy mixes dissolve smoothly and coat the meatballs evenly.
• Try to keep the cover on the slow cooker during cooking — lifting the lid slows the cooking process and makes it take longer.
• If you want to use homemade meatballs, make sure they’re similar in size to store-bought ones and cook them to a safe internal temp (about 160°F for beef or pork, 165°F for poultry).
• For an extra flavor boost, sear homemade or thawed meatballs quickly in a hot skillet before adding them to the slow cooker. It’s optional, but adds lovely browning and texture.
• Leftovers store perfectly in an airtight container in the fridge for up to 4 days. Reheat gently on the stove or microwave, adding a splash of broth or water if the gravy thickened too much.

Serving Suggestions and Add-Ins

I love serving these slow cooker salisbury steak meatballs over creamy Cream Cheese Mashed Potatoes alongside some steamed veggies. It’s the perfect classic combo. You can also plate them over egg noodles or fluffy white rice for a quick and tasty dinner. Don’t forget a sprinkle of fresh parsley on top — it adds a pop of color and freshness that makes this meal extra inviting.

Storing and Reheating Leftovers

Keep your leftovers tasting fresh by storing the meatballs and gravy in an airtight container in your fridge. They’ll stay good for up to 4 days. When reheating, warm gently on the stove or microwave until heated through. If the gravy looks too thick, just stir in a little water or broth to loosen it back up — easy peasy!

Answers to Common Questions

What Type of Frozen Meatballs Do I Use?

Use your favorite kind of frozen meatballs. I usually pick about 26 ounces, which comes to 30-35 meatballs. Classic homestyle ones are my go-to, but turkey or Italian meatballs are great swaps too. Costco’s frozen meatballs work well and I just count out a bag for this recipe.

Do I Need To Thaw The Meatballs Before Cooking Them?

No need at all! Just dump frozen meatballs right into your slow cooker — thawing isn’t necessary and saves time.

Can I Use Homemade Meatballs?

Absolutely! Just make sure your homemade meatballs are about the size of store-bought ones, around 30 meatballs total. They’ll also need to reach a safe internal temperature — 160°F for beef or pork, 165°F for poultry.

What Is The Cornstarch Slurry For?

The slurry thickens the gravy after cooking. If you prefer your gravy thinner, skip this step and serve as-is. But if you want a nice thick gravy coating your meatballs, mixing cornstarch with cold water and stirring it back into the crockpot for 10 minutes will get you that perfect texture.
