Ingredients For Crockpot Mississippi Meatballs

This recipe is built on big flavor with almost no prep. You’re layering frozen meatballs with savory seasoning, tangy peppers, and plenty of butter so everything melts together into that classic Mississippi-style sauce.

It’s simple, but every ingredient matters. The au jus brings depth. The ranch adds that signature punch. The pepperoncini juice cuts through the richness. And the butter? That’s what makes the sauce silky and bold.

Ingredients For the Crockpot Mississippi Meatballs:

1 (26-ounce) bag frozen meatballs
1 packet au jus gravy mix
1 packet ranch seasoning mix
1 (16-ounce) jar pepperoncini peppers (with juice)
½ cup water
½ cup butter, diced

Savory. Buttery. Tangy. Built to coat every meatball.

How to Make These Crockpot Mississippi Meatballs

Start by placing the frozen meatballs directly into a 6-quart slow cooker. No need to thaw them. They’ll heat through perfectly as they cook.

Sprinkle the entire packet of au jus mix and the ranch seasoning mix evenly over the top. Try to distribute it so every meatball gets a little coverage.

Pour the pepperoncini peppers into the crockpot, including the juice from the jar. That liquid is part of the flavor base, so don’t drain it. Add the ½ cup of water to help everything blend into a smooth sauce as it cooks.

Scatter the diced butter evenly over the top. As it melts, it will combine with the seasoning and pepperoncini juice to create that rich, glossy Mississippi-style sauce.

Cover and cook on LOW for 3–4 hours, stirring occasionally if you’re around. The meatballs should be heated through and fully coated in the buttery, savory sauce.

Once done, give everything one final stir so the sauce evenly clings to each meatball.

Serve hot as an appetizer straight from the crockpot, or spoon over mashed potatoes, rice, or noodles for a hearty meal.

Substitutions and Variations

Crockpot Mississippi meatballs are hard to mess up, but you can absolutely tweak them to fit your taste.

If you do not have the whole pepperoncini peppers you can use the sliced ones instead. You can even toss in a pinch of red pepper flakes for extra kick.

Prefer less salt? Use low-sodium au jus and ranch packets, or reduce the added water slightly so the flavor stays balanced without getting too salty.

You can also swap in turkey or chicken meatballs if you want something lighter. The sauce still works beautifully with leaner proteins.

Want it thicker? After cooking, remove the lid and let it sit on warm for 10–15 minutes to slightly reduce. Or stir in a small cornstarch slurry if you prefer a thicker gravy-style finish.

Same bold flavor. Just dialed to your preference.

What to Serve With Crockpot Mississippi Meatballs

These crockpot Mississippi meatballs can swing both ways — appetizer or full comfort meal.

For a party, serve them straight from the slow cooker with toothpicks. The sauce clings perfectly, and they stay warm for hours.

If you’re turning them into dinner, spoon them generously over creamy mashed potatoes. The buttery pepperoncini sauce settles into the potatoes and it’s honestly hard to beat.

They’re also great over white rice, egg noodles, or even tucked into toasted hoagie rolls for a messy, savory sandwich situation.

Keep it simple on the side. A crisp green salad or roasted vegetables balance out the richness.

Savory meatballs. Silky sauce. Endless options.

Leftovers and Storage

If you somehow have leftovers, they store beautifully.

Let the meatballs cool completely, then transfer them (with plenty of that sauce) into an airtight container. Store in the refrigerator for up to 4 days.

To reheat, warm them in a saucepan over medium-low heat until heated through, or microwave in 30-second intervals, stirring in between. If the sauce thickens too much in the fridge, add a small splash of water or broth to loosen it up.

They also freeze well. Store in a freezer-safe container for up to 2 months. Thaw overnight in the refrigerator before reheating.

The flavor actually deepens a bit the next day. Richer. Bolder. Just as good.

FAQs

Can I use homemade meatballs instead of frozen?

Yes. Homemade meatballs work great in this recipe. Just make sure they’re fully cooked before adding them to the slow cooker so they hold their shape while the sauce develops.

Are crockpot Mississippi meatballs spicy?

Not really. Pepperoncini peppers add tang and a mild warmth, but they’re not very spicy. If you want more heat, you can add extra pepperoncini or a pinch of red pepper flakes.

Can I cook Mississippi meatballs on high?

Yes. If you’re short on time, cook them on HIGH for 1½–2 hours. The flavor is still great, but cooking on low gives the sauce a little more time to develop.

Can I thicken the sauce?

If you prefer a thicker sauce, mix 1 tablespoon cornstarch with 1 tablespoon water and stir it into the crockpot during the last 15 minutes of cooking.
