Crock-Pot Chicken Meatballs In Tomato Sauce

These Crock-Pot chicken meatballs made in tomato sauce are one of my go-to appetizer recipes for parties. They taste great, you can make them ahead of time and they can stay in the slow cooker on warm for a few hours without losing their flavor.

As you may know (if you’ve been here before), I love to entertain.

And I always get carried away decorating for my parties, so I never have time to make food that is too complicated.

Which is why these Crock-Pot chicken meatballs are one of my all-time favorite appetizers.

You can make them a day or two ahead of time.

Then on the day of the party, plug them in a few hours ahead of time and forget about them.

And they’re easy to serve. I just put out some toothpicks beside the slow cooker and everyone helps themselves.

Oh, and did I mention they taste great? There are never any left at the end of the day.

How to make chicken meatballs in tomato sauce

The Prep Work

Start by chopping 2 onions.

Reserve 1/2 cup of chopped onions for the meatballs. The rest will go in the tomato sauce.

Then mince 3 cloves of garlic. You’ll need 2 of them for the tomato sauce and 1 for the meatballs, so you might want to keep them separate so you know how much to put in each.

In a small bowl, beat a large egg with a fork.

Make the tomato sauce

The first step in this dish is to make the tomato sauce.

For the best flavor, I like to cook this in a large pot on the stove.

However if you want to make it in the Crock-Pot, combine all of the ingredients (leaving out the olive oil) in your slow cooker and cook on low for 3 to 4 hours.

To make the tomato sauce in a pot, heat 2 Tablespoons of olive oil over medium heat.

Add in the chopped onion (minus the 1/2 cup reserved for the meatballs), 2 cloves minced garlic, 1 teaspoon dried basil and a pinch of red pepper flakes.

Cook stirring occasionally until the onion is softened, about 5 minutes.

Then mix in 2 28-ounce cans of crushed tomatoes, 1 1/2 teaspoons salt, 1 teaspoon ground black pepper and 2 Tablespoons dried parsley.

Lower the temperature to medium-low and simmer for about 45 minutes.

Make the meatballs

While the sauce is simmering, put the meatballs together.

In a large bowl, combine 1/4 cup milk, 1 cup bread crumbs, 1/2 cup grated parmesan cheese, 2 teaspoons dried parsley, 1/2 cup chopped onion, 1 clove minced garlic, 1 1/2 teaspoons salt, 1/2 teaspoon ground black pepper, the beaten egg and 2 pounds ground chicken, turkey or beef.

Mix well. You will probably have to dig in with your hands to get everything combined.

Form 1 to 2 inch balls from the mixture.

Try to make them all about the same size so that they cook evenly.

Using a round Tablespoon works well for making consistently-sized (and round) meatballs.

Cook the meatballs in tomato sauce

When the sauce is finished, it’s time to combine the two.

Line the Crock-Pot with a slow cooker liner* if you have one. They make clean up so much easier!

Put a single layer of meatballs in the bottom of the slow cooker.

Pour half of the tomato sauce over the top. The meatballs should be covered.

Then add a second layer of meatballs and pour the remaining sauce over the top.

Put the lid on the Crock-Pot and cook on high for 3 hours, or until the meatballs are no longer pink in the middle.

These can easily stay in the slow cooker on the “Warm” setting for a few hours, which is one of the reasons I love to serve them at parties.

To make the meatballs ahead of time

If you want to get this dish ready a day or two in advance, you can prepare the tomato sauce and the meatballs.

Then store them separately in the refrigerator until the day of the party.

Follow the same instructions for cooking them, but increase the cook time to 4 hours.
