This is my ultimate busy-night comfort meal: slow cooker cheddar beef meatballs that come together with just five ingredients and almost no effort. I literally dump canned cheddar cheese soup over a bag of frozen beef meatballs, add three pantry staples, and let the slow cooker do its thing. It reminds me of the cozy, cheesy casseroles I grew up with in the Midwest, but in meatball form and with way less work.
This is the kind of recipe I lean on when I’m juggling work, errands, and a hungry household—it’s always a yes in my house.
Slow Cooker 5-Ingredient Cheddar Beef Meatballs

For a little extra flavor without adding more ingredients, you can swap the garlic powder and onion powder amounts to your taste, or add a pinch of black pepper or smoked paprika if you don’t mind going slightly beyond the 5-ingredient base. If you prefer a thinner sauce, stir in an extra splash of milk at the end of cooking until it reaches your desired consistency. For a thicker, stick-to-your-ribs sauce, let the slow cooker sit uncovered on WARM for 10 to 15 minutes to reduce slightly.
To make this feel more like a full meal in one pot, you can stir in a bag of thawed frozen mixed vegetables during the last 30 minutes of cooking, just until heated through.
Food safety tips: Always use fully cooked frozen beef meatballs from a reputable brand and keep them frozen until you’re ready to add them to the slow cooker. Make sure your slow cooker reaches a safe temperature—on HIGH it should bring the meatballs and sauce above 165°F; if you’re unsure, use an instant-read thermometer to check the internal temperature of a meatball in the center. Do not leave the cooked meatballs on the counter; refrigerate leftovers within 2 hours in shallow containers. Reheat leftovers gently on the stove or in the microwave until steaming hot all the way through before serving.
