Throw frozen meatballs in your slow cooker and let them soak up a deep, classic gravy while you do your thing. Before you know it, you'll have a cozy, old-school comfort meal with almost no hands-on work. Perfect for those nights you need good food and zero stress.
One crazy busy night, I threw this together and it totally saved dinner. Now I never let my freezer run out of meatballs in case I need this fix fast.
Tasty Ingredients
- Cold water: lets you blend up the cornstarch so it gets smooth and creamy
- Cornstarch: thickens the sauce to the perfect glossy finish — make sure to whisk with cool water first
- Worcestershire sauce: gives that extra punch of deep flavor; sniff before you pour to make sure it's rich
- Ketchup: adds tang plus a little sweetness; don't overthink it, any basic ketchup is fine
- Onion soup mix: brings big, savory taste and a little sweetness, especially with those yummy dried onions that soak up flavor
- Brown gravy mix: thickens and rounds out the flavors with a real home-cooked vibe; go for a mix with simple ingredients
- Reduced salt beef broth: builds up the savory base without making things overly salty—double-check that label, since the mixes have salt too
- Frozen meatballs: grab an all-beef brand for that classic feel, or swap in turkey for something lighter—the better the meatball, the better the end result
Simple Step-by-Step
- Serve:
- Scoop those hot, gravy-soaked meatballs onto mashed potatoes, noodles, or whatever you're feeling. Don't forget a big ladle of that tasty sauce. Top with parsley or herbs if you want to be fancy.
- Thicken the Gravy:
- Right before serving, blend cold water and cornstarch in a cup—no lumps! Pour your smooth mix into the slow cooker, give it a good stir, and let it cook a few more minutes so the sauce thickens up.
- Slow Cook:
- Put on the lid and let things burble away for around five or six hours on low. You'll come back to perfect, tender meatballs swimming in gravy.
- Combine and Start Cooking:
- Pour the gravy over the meatballs, and give everything a gentle stir to coat. Pop the lid on and get it going.
- Mix the Gravy Base:
- Dump the beef broth, brown gravy mix, onion soup mix, ketchup, and Worcestershire into a bowl. Whisk those together until smooth — no dry bits hiding!
- Arrange the Meatballs:
- Tip all those frozen meatballs into the cooker and spread them out so they heat evenly.
- Prep the Slow Cooker:
- Hit your slow cooker with a layer of nonstick spray so everything cleans up easy and nothing sticks later.

I always reach for the onion soup mix in this one—it reminds me of the Sunday table at my folks' house. Plus, my kids basically demand their mashed potatoes drowned in that rich gravy, and honestly, so do I.
Easy Storage
Let leftovers cool, then seal in a container in the fridge for up to four days. Warm them back up with a splash of broth or water if the sauce gets thick. Freeze in a good container for up to three months. Move to the fridge overnight to thaw before reheating.
Swap Options
No beef broth? Pour in chicken broth and up the Worcestershire a bit to keep flavor strong. Homemade meatballs also work if you've got them handy. Grab gluten-free brown gravy or onion soup mix to change things up. Sometimes, at the end, I'll stir in a spoonful or two of sour cream for an extra silky bite.
How to Serve
Ladle these over soft egg noodles or creamy mashed potatoes for a stick-to-your-ribs meal. Want lighter? Dump onto steamed rice. Got leftovers? Pile them into sandwich rolls and make meatball subs for lunch.

Story Behind It
Classic Salisbury steak started as a clever way to enjoy beef on a budget way back in the day. Swapping out patties for meatballs gives you the same bold flavors but in a way that's simple and family friendly, even when you're swamped. It's proof traditional ideas never really go out of style—they just get a modern makeover.
