Step-by-Step Guide to Perfect Party Meatballs (Slow Cooker)
Alright, let’s get these party meatballs rolling! Seriously, it couldn’t be easier, and watching them bubble away in the slow cooker just makes me happy. Follow these simple steps and you’ll have a crowd-pleasing appetizer in no time:
Mix the Meatball Magic: Grab your biggest bowl and toss in the ground beef, breadcrumbs, milk, that beaten egg, salt, and pepper. Give it all a good, gentle mix. You want it combined, but don’t overdo it, or your meatballs might get tough! Trust me on this one.
Roll ‘Em Up: Now for the fun part! Roll the mixture into little 1-inch balls. For perfectly uniform meatballs that look super professional, I love using a small cookie scoop โ it makes them all the same size in a flash!
Slow Cooker Welcome: Carefully place all those lovely meatballs right into your slow cooker. Don’t worry about layering them perfectly, they’ll snuggle up together.
Sauce Swap: In a separate little bowl, whisk together that bottle of chili sauce and the jar of grape jelly until it’s nice and smooth. It sounds a little wild, but this combo is pure gold!
Sauce Shower: Pour that amazing sauce all over the meatballs in the slow cooker. Make sure every single meatball gets a nice bath in that sweet and savory goodness.
Let the Slow Cooker Shine: Pop the lid on, set it to LOW, and let it cook for about 2 hours. You’ll want to give them a gentle stir every now and then just to make sure everything is heating up evenly. They’re ready when they’re totally heated through and smelling absolutely incredible. If you’re a chili fan, it has a similar vibe to the sauce you’d find in this cozy beef chili!

Tips for Success with Your Party Meatballs
I’ve made these Party Meatballs (Slow Cooker) more times than I can count, and over the years, I’ve picked up a few little tricks to make sure they turn out perfectly every single time. Here are my go-to tips:
Don’t Overmix the Meat: This is SO important for tender meatballs! When you’re mixing the beef, breadcrumbs, and other ingredients, just combine them until they’re blended. If you mix too much, the meatballs can get tough and a bit rubbery, and nobody wants that!
Submerge for Success: Make sure those meatballs are happy and swimming in that delicious chili sauce and grape jelly mixture. If some are sticking out, they can dry out. A gentle stir every hour or so really helps ensure they all cook evenly and stay nice and moist.
Know Your Slow Cooker: Every slow cooker is a little different! Mine seems to run a bit hotter, so 2 hours is usually perfect for me. If yours tends to run cooler, you might want to check them at the 2.5-hour mark. Just peek inside โ they should be heated through and the sauce should be bubbly. You can always cook them a little longer if needed, but you can’t un-cook them!
Serving Suggestions for Your Slow Cooker Party Meatballs
Okay, now that your Party Meatballs (Slow Cooker) are all warm and smelling heavenly, how should you serve them up? The classic way, of course, is to pop them into a serving dish and stick a bunch of toothpicks in them. It’s just the easiest way for guests to grab a bite!

But you know me, I love a good twist! These are fantastic piled high on mini slider rolls to make little meatball sandwiches, or even served over a bed of fluffy rice for a more substantial appetizer. If you’re feeling adventurous, they’re also amazing as a topping for nachos! However you choose to serve them, they disappear fast!
Storage and Reheating Instructions
Got leftovers? Lucky you! These Party Meatballs (Slow Cooker) are still delicious the next day. Just pop any extra goodies into an airtight container and stash them in the fridge. They’ll be good for about 3 to 4 days. When you’re ready for a snack, you can zap them in the microwave for a quick reheat, or if you want them to stay extra tender, pop them in a low oven (around 300ยฐF or 150ยฐC) for about 10-15 minutes until they’re warmed through.

Frequently Asked Questions about Party Meatballs
Have a few lingering questions about my famous Party Meatballs (Slow Cooker)? I get it! It’s always good to know a little extra before you dive in. Here are some things folks often ask:
Can I make these ahead of time?
Oh, absolutely! That’s one of the best parts. You can totally make the meatballs the day before and store them in the fridge. Just pop them into the slow cooker with the sauce when you’re ready to cook. Or, you can even cook them fully ahead of time, let them cool, and then reheat them gently in the slow cooker on the ‘warm’ setting for about an hour before serving. So handy!
What other sauces can I use besides chili sauce and grape jelly?
While that classic chili sauce and grape jelly combo is my absolute favorite for a reason (it’s SO good!), you can definitely get creative! Many people love a BBQ sauce base, or even sweet and sour sauce. For something a bit different, check out these garlic butter meatballs or these red wine meatballs for inspiration on different flavor profiles. Just make sure whatever sauce you choose is enough to coat the meatballs well!
Can I bake these instead of using a slow cooker?
You sure can! If you don’t have a slow cooker handy, just bake the meatballs on a baking sheet at 375ยฐF (190ยฐC) for about 15-20 minutes until they’re browned and cooked through. While they’re baking, whisk together your chili sauce and grape jelly in a saucepan. Once the meatballs are done, drain off any excess fat, pour the sauce over them, and either toss to coat and serve immediately, or gently simmer them in the sauce on the stovetop for another 10-15 minutes to let the flavors meld.
Do I have to use grape jelly? Can I use another jelly?
Nope, you don’t *have* to use grape jelly! While it’s the classic choice for this recipe, raspberry or strawberry jelly can also add a lovely fruity sweetness that works really well with the savory chili sauce. Just make sure it’s a jelly and not jam, as jam can sometimes have more fruit chunks that might affect the smoothness of the sauce.

Nutritional Information
Just a heads-up, these numbers are estimates and can totally change based on the brands you use and the exact size of your meatballs! Usually, you’re looking at around 150-200 calories per meatball, with about 8-12g of fat, 10-15g of protein, and 10-15g of carbs. Enjoy!
