Ingredient Notes
Use frozen fully cooked beef meatballs here—not raw ones. That matters. I usually buy whatever brand is on sale as long as they’re a decent size and labeled fully cooked. The Italian-seasoned kind will work in a pinch, though plain beef meatballs keep the flavor more like that classic cheesy casserole situation.
For the cheddar cheese soup, this is one of those places where the familiar red-and-white can is reliable. Store brand is generally fine too, though I think some of them are a little thicker. Not bad, just thicker. You can always loosen the sauce with a splash of milk at the end if needed.
Any milk works. Whole milk makes the sauce a touch richer, naturally, but 2% works well too. Skim works in a pinch when that is all you have. Not glorious, but fine.
Garlic powder and onion powder do the quiet work here. Don’t use garlic salt by accident unless you want to spend the evening drinking water and regretting your choices.
Ingredients
- 1 (32-ounce) bag frozen fully cooked beef meatballs
- 2 (10.5-ounce each) cans condensed cheddar cheese soup
- 1 cup milk, whatever kind you have on hand
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- Pinch of salt and black pepper, if needed after cooking—I usually wait and taste first
Instructions
- Place the frozen fully cooked beef meatballs in the bottom of a 4- to 6-quart slow cooker, spreading them out as evenly as you can. They do not have to be arranged like little soldiers; we’re making dinner, not planning a parade.
- In a medium bowl, whisk together the condensed cheddar cheese soup, milk, garlic powder, and onion powder until the mixture is smooth. It may look a little thick and sort of alarming at first, but that is normal. The milk helps it relax as it cooks—honestly, something we could all stand to do.
- Pour the cheddar soup mixture evenly over the frozen meatballs. Use a spoon to gently nudge down any meatballs sitting up high and looking dry. They don’t all have to disappear beneath the sauce, but most of them should get a good coating.
- Cover the slow cooker and cook on LOW for 4 to 5 hours or on HIGH for 2 to 3 hours, until the meatballs are heated through and the sauce is hot and bubbly. If you’re using HIGH, I’d start checking around the 2-hour mark. Slow cookers can run at different temperatures.
- About halfway through the cooking time, gently stir the meatballs and sauce so everything gets coated evenly, then put the lid back on and let it keep going. Try not to lift the lid twelve times out of curiosity. I know it smells good. Every time you open it, you add cooking time, and then suddenly it’s 6:40 and everybody is circling the kitchen like vultures.
- When the meatballs are done, give everything one final gentle stir. Taste the sauce and add a pinch of salt and black pepper if it needs it. Depending on the meatballs and soup you use, it may not need much salt at all.
- Serve the meatballs hot over buttery egg noodles, mashed potatoes, or rice, and make sure to ladle plenty of sauce over the top. They are also wonderful tucked into toasted hoagie rolls for messy sandwiches. Put out napkins. Real napkins if you’re feeling optimistic, paper ones if you expect a mess.
Variations
Add a little black pepper and smoked paprika for a warmer, faintly smoky flavor. Serve them on rice with steamed broccoli for a perfectly sensible and balanced meal.
If the sauce seems too thick when the meatballs are finished, stir in a small splash of milk until it looks right to you. For a thicker, stick-to-your-ribs version, leave the slow cooker uncovered on WARM for about 10 to 15 minutes. Keep an eye on it, though. The sauce can get thicker than intended. Still edible. Not exactly elegant.
You can also stir in a bag of thawed frozen mixed vegetables during the last 30 minutes of cooking if you want to make it feel more like a full one-pot meal. Peas and carrots are especially good with the cheddar sauce. Adding frozen vegetables straight from the freezer can cool everything down enough that dinner is late. Not a catastrophe, but nobody needs extra reasons for people to be grumpy at 7 p.m.
Storage & Reheating
Leftovers keep in the refrigerator for up to 3 or 4 days in a covered container. I try to get them put away within two hours, though that depends on whether everyone has wandered off after dinner and left me alone with the dishes. Which they usually have. Funny how that works.
For reheating, warm the meatballs gently in a saucepan over low heat with a splash of milk, stirring now and then until the sauce is creamy again and the meatballs are steaming hot. The microwave works too—cover them loosely and heat in short intervals, stirring between rounds if you can. The sauce tends to tighten up in the fridge, but milk brings it right back.
The leftovers are also pretty good cold out of the container. I’m not recommending that. I’m just saying these are pretty good the next day.
Final Notes
There’s something comforting about a recipe that doesn’t ask much of you. Dump, stir, cover, wait. Some days that is exactly the level of ambition available, and frankly, it ought to be enough.
I make these when the weather is gray, when the calendar is ridiculous, when I’ve spent the afternoon sorting through a drawer full of batteries that are all probably dead. I make them when somebody needs a soft dinner. The kind you can eat from a bowl on the couch, maybe with a green salad if you’re trying to be virtuous, maybe with garlic bread if you are not.
And I know canned soup isn’t fashionable. Neither are sensible shoes, but here we are. Sometimes the old reliable things earn their spot because they work.
