Key Ingredients & Substitutions
Frozen Meatballs: I love using frozen fully cooked meatballs for convenience. Beef works great, but for a twist, you can switch to turkey or chicken meatballs. They are flavorful and easy to manage. If you want to make your own, try mixing ground meat with breadcrumbs and spices!
Ranch Seasoning Mix: This mix gives a creamy, tangy kick. If you don’t have it, consider using Italian seasoning or Hidden Valley Ranch dressing instead. Homemade ranch seasoning is also a fun option if you like to mix your own!
Au Jus Gravy Mix: This contributes a rich, beefy flavor. If you can’t find it, try using beef broth or stock, along with a splash of soy sauce for depth. You could also use brown gravy mix if that’s what you have on hand.
Pepperoncini Peppers: These add a beautiful tang to the dish. If you can’t find them, banana peppers make a nice substitute for a similar flavor without too much heat. For spice lovers, jalapeños can give a kick!
How Do I Make the Sauce Just Right?
Getting the sauce flavorful is key for these meatballs! Here’s how to ensure it’s perfect:
- Mix ranch seasoning and au jus gravy together before adding it on top of the meatballs for an even stronger flavor.
 - Don’t skip the butter! It elevates the sauce, making it creamy and rich.
 - Using the pepperoncini juice is essential! It balances the richness with a bit of tang. Adjust the amount based on your taste – add more if you love that kick!
 
Stir everything once halfway through cooking to help distribute those delicious flavors. Enjoy the warm, comforting dish!

Mississippi Meatballs for Slow Cooker Potluck
Ingredients You’ll Need:
- 2 pounds frozen fully cooked meatballs (beef or a mix of beef and pork)
 - 1 packet (1 ounce) ranch seasoning mix
 - 1 packet (1 ounce) au jus gravy mix
 - 1/2 cup unsalted butter (1 stick)
 - 6-8 pepperoncini peppers, with some juice
 - Fresh parsley, chopped (for garnish)
 
How Much Time Will You Need?
This recipe takes about 10 minutes to prepare, and then you’ll let the slow cooker do the work! Cook on low for 4 to 6 hours or on high for 2 to 3 hours. So, set it and forget it while you enjoy your day!
Step-by-Step Instructions:
1. Prepare the Slow Cooker:
Start by placing the frozen meatballs directly into the slow cooker. You don’t need to thaw them beforehand; they will cook perfectly from frozen!
2. Add Seasoning and Mix:
Sprinkle the ranch seasoning and au jus gravy mix evenly over the meatballs. This step is crucial for achieving that delicious flavor profile!
3. Incorporate the Butter:
Cut the stick of butter into chunks and place it on top of the meatballs. The melting butter will help create a rich sauce that coats everything.
4. Add the Pepperoncini:
Now, add the pepperoncini peppers and pour about 1/4 cup of the pepperoncini juice over the top. This gives the meatballs that signature tangy flavor.
5. Set to Cook:
Cover the slow cooker with the lid and set it to cook. Choose low for a longer cook time (4 to 6 hours) or high for a quicker meal (2 to 3 hours). The meatballs are done when they are heated through and the sauce is bubbling.
6. Stir Before Serving:
Once cooked, give the mixture a gentle stir to ensure everything is well combined. This helps distribute the flavors evenly throughout the dish.
7. Garnish and Serve:
Finally, garnish with freshly chopped parsley for a pop of color and freshness! Serve the meatballs warm, and watch them disappear at your potluck!
Enjoy these tangy, buttery, and savory meatballs that are sure to be a crowd-pleaser!

Can I Use Fresh Meatballs Instead of Frozen?
Yes! If you prefer using fresh meatballs, you can absolutely do so. Just adjust the cooking time: cook them on low for about 2-3 hours or on high for around 1-2 hours until they’re cooked through.
What Can I Substitute for Pepperoncini Peppers?
If you’re not a fan of pepperoncini, banana peppers make a great alternative with a similar flavor. For those who enjoy a little heat, try using jalapeños. Just be sure to adjust the amount based on your heat preference!
How Should I Store Leftovers?
Leftover Mississippi meatballs can be stored in an airtight container in the fridge for up to 3 days. To reheat, simply warm them in the microwave or on the stovetop over low heat until heated through. You might want to add a splash of water or broth to the pan to keep the sauce creamy.
Can I Make This Ahead of Time?
Absolutely! You can prepare the meatballs and sauce a day in advance. Just combine everything in the slow cooker insert (if it’s removable) and refrigerate overnight. On the day of your event, simply place it back in the slow cooker and heat on low until warmed through before serving.
