These slow cooker chicken meatballs in creamy Alfredo are a rich, cozy dinner with almost no work. Chicken meatballs simmer in jarred Alfredo sauce thinned with a little broth and seasoned with garlic and onion powder. Melty mozzarella goes in at the end.

Prep takes about 15 minutes. After that, the crockpot does the work while you get on with your day. Serve the meatballs over pasta, rice, or mashed potatoes for an easy meal that feels like a treat.

Why This Recipe Works

Chicken meatballs are lighter than beef, and they soak up flavor from the sauce as they cook. Low, gentle heat keeps them tender and juicy instead of rubbery.

Jarred Alfredo can get very thick in a slow cooker. Adding half a cup of chicken broth keeps the sauce smooth and pourable for the whole cook time. It also adds savory flavor that makes the sauce taste less like it came from a jar.

The mozzarella is the finishing touch. Stirred in 10 minutes before serving, it melts into the sauce and gives it that cheesy, stretchy texture everyone loves. Adding it at the end keeps it from getting greasy or stringy.

This recipe is also very kid friendly. The flavors are mild and creamy, with no spice and nothing green unless you add it. It is a good one to keep in your back pocket for nights when you need a sure thing. A bag of frozen meatballs and a jar of Alfredo in the pantry means dinner is always close.

Ingredients and Easy Swaps

Chicken meatballs: 1 pound, store bought or homemade. Fully cooked frozen chicken meatballs are the easiest choice. Turkey meatballs work the same way.
Alfredo sauce: One jar, about 15 ounces. Roasted garlic Alfredo adds even more flavor.
Chicken broth: 1/2 cup. Milk works too, for an even creamier sauce.
Garlic powder, onion powder, and black pepper: These add depth without any chopping. Add a pinch of Italian seasoning if you like herbs.
Mozzarella: 1/2 cup shredded. Parmesan is a sharper, saltier swap. Use half of each for the best of both.

How to Make It at a Glance

Place the chicken meatballs in the crockpot.
In a bowl, mix the Alfredo sauce, broth, garlic powder, onion powder, and pepper. Pour it over the meatballs.
Cover and cook on low for 4 to 5 hours or on high for 2 to 3 hours.
Check that the meatballs are 165°F in the center.
Stir in the mozzarella 10 minutes before serving.
Serve over pasta, rice, or mashed potatoes.

Common Mistakes to Avoid

Cooking too long. Cream sauces can break and turn oily if they cook far past the time. Stick close to the range in the recipe.
Skipping the broth. Without it, the sauce can scorch on the sides of the crock and get gluey.
Adding cheese at the start. Hours of heat make mozzarella clump. Wait until the end.
Not checking raw homemade meatballs. If you make your own and put them in raw, use a thermometer. Ground chicken must reach 165°F.

If the sauce gets too thick by the end of cooking, stir in a few tablespoons of warm broth or milk until it is smooth again. If it looks thin, leave the lid off for the last 15 minutes.

Variations

Spinach Alfredo: Stir in 2 big handfuls of baby spinach with the cheese. It wilts in a few minutes.
Broccoli Alfredo: Add 2 cups of frozen broccoli florets for the last 30 minutes.
Sun dried tomato: Add 1/4 cup of chopped sun dried tomatoes for a sweet, tangy pop.
Cajun: Swap the onion powder for 1 teaspoon of Cajun seasoning for a little heat.
Mushroom: Add 1 cup of sliced mushrooms at the start.

What to Serve With It

Fettuccine is the classic match for Alfredo, but penne, rotini, and egg noodles all work. Rice and mashed potatoes are great for soaking up the sauce. For a lower carb plate, try zucchini noodles or roasted spaghetti squash.

Since the dish is rich, pair it with something fresh. A Caesar salad, steamed green beans, or roasted asparagus balance it well. Garlic bread is never a bad idea. These meatballs also make a fun party appetizer. Keep them on warm and set out toothpicks.

Make Ahead, Storage and Reheating

You can mix the sauce the night before and keep it covered in the fridge. In the morning, add the meatballs to the crock, pour the sauce over, and turn it on.

Store leftovers in a sealed container in the fridge for up to 3 days. Cream sauces thicken when cold, so add a splash of milk or broth before reheating. Warm gently on the stove over low heat or in the microwave at half power, stirring often, until the meatballs are hot all the way through. Freezing is not recommended since Alfredo sauce tends to separate when thawed.

FAQ

Yes. Double everything and use a 6 quart slow cooker. Cook times stay about the same.

How many meatballs are in a pound?
Usually 16 to 20 small meatballs, which serves about 4 people over pasta.
