How to Make Best Slow Cooker Salisbury Steak Meatballs (Frozen Meatballs)

1. Place the frozen meatballs in the bottom of your slow cooker in an even layer.
2. In a skillet over medium heat, sauté the onions and mushrooms with a pinch of salt until softened and browned, about 6-8 minutes. Add garlic and cook 1 minute more until fragrant.
3. Transfer the sautéed onion, mushroom, and garlic mixture to the slow cooker over the meatballs.
4. In a medium bowl, whisk together beef broth, ketchup, Worcestershire sauce, soy sauce, and dried thyme. Pour the mixture over the meatballs and vegetables.
5. Cover and cook on low for 4 hours, or until meatballs are tender and heated through.
6. About 15 minutes before serving, stir together cornstarch and cold water to make a slurry. Slowly stir it into the slow cooker liquid to thicken the gravy.
7. Add the heavy cream and stir well. Cook uncovered for 10-15 minutes more until the gravy is thick and creamy.
8. Season with salt and freshly ground black pepper to taste.
9. Garnish with chopped fresh parsley and serve hot over mashed potatoes, egg noodles, or rice for a complete comforting meal.

Tips for the Best Results

• Brown the mushrooms and onions first for deeper flavor and better texture in your gravy.
• Use low sodium beef broth to control saltiness in the dish.
• Don’t skip the cream; it makes the gravy luxuriously smooth and rich.
• Make sure to stir the cornstarch slurry well to avoid lumps before adding to the slow cooker.
• Leftovers taste even better the next day as flavors continue to meld.

Storage and Reheating

Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop over medium-low heat or in the microwave, stirring occasionally to maintain the creamy gravy consistency.

For longer storage, freeze the meatballs and gravy in a freezer-safe container for up to 3 months. Thaw overnight in the refrigerator before reheating thoroughly.

Frequently Asked Questions

Can I use fresh meatballs instead of frozen?

Yes, fresh meatballs will work great too. You may reduce the slow cooking time slightly since fresh meatballs typically cook faster. Just check for doneness and tenderness.

What can I serve with slow cooker Salisbury steak meatballs?

This dish pairs wonderfully with mashed potatoes, egg noodles, steamed rice, or even buttered pasta. Roasted vegetables or a simple green salad also make great sides.

Can I make this recipe gluten-free?

Absolutely. Use gluten-free beef broth and tamari or a gluten-free soy sauce alternative. Double-check your frozen meatballs to ensure they’re gluten-free as well.

How thick should the gravy be?

The gravy should be thick enough to coat the back of a spoon but still pourable. Adjust the cornstarch slurry quantity if you prefer a thinner or thicker sauce.
