How to Make Slow Cooker Chicago Style Meatballs Recipe
Step 1: Place Meatballs in the Slow Cooker
The best part about this recipe is how simple it is to start—just take your frozen meatballs straight from the bag and arrange them evenly at the bottom of your crockpot. No thawing required, making it perfect for busy days or last-minute plans.
Step 2: Add Ingredients on Top
Layer the brown gravy mix, Lipton onion soup mix, and beef broth over the meatballs. Then add the chopped giardiniera, distributing it evenly for that bold tang in every bite. This layering ensures the flavors meld beautifully as they cook.
Step 3: Cook Low and Slow
Cover your slow cooker and set it on high for 2 to 3 hours, or low for 4 to 6 hours. This slow simmer allows the meatballs to soak up all the savory sauce and vibrant giardiniera flavors and become irresistibly tender and juicy.
Step 4: Stir and Garnish
Before serving, give the meatballs a gentle stir to mix everything well. Sprinkle on some fresh chopped parsley if you like a little herby brightness and a pop of color—it’s a small touch that makes a big difference!

Make Ahead and Storage
Storing Leftovers
After enjoying your meal, place leftover meatballs and sauce in an airtight container and refrigerate. They’ll stay fresh and flavorful for up to 3 days, making for a quick and tasty lunch or dinner the next day.
Freezing
If you want to save your Slow Cooker Chicago Style Meatballs Recipe for later, freezing is a great option. Store the meatballs and sauce in a freezer-safe container or heavy-duty zip-top bag, where they will keep well for up to 3 months. Just thaw overnight in the fridge before reheating.
Reheating

FAQs
Can I use homemade meatballs instead of frozen?
Absolutely! Homemade meatballs can add a personal touch, but be sure they’re fully cooked before adding them to the slow cooker to ensure safety and the best texture.
Is it possible to make this recipe spicy?
Yes, using the hot version of Chicago-style giardiniera really amps up the heat. You can also add red pepper flakes or a dash of hot sauce if you like more spice.
Can I prepare this recipe without a slow cooker?
You can, but the slow cooker really brings out the rich flavors and perfect tenderness. On the stovetop, simmer on low heat for about 30 to 45 minutes, stirring occasionally to prevent sticking.
What can I substitute for giardiniera if I can’t find it?
Look for pickled mixed vegetables or use a combination of chopped pickles, olives, and mild peppers to mimic the tangy crunch that giardiniera provides.
Is this recipe gluten-free?
Check the ingredient labels for the gravy mix and onion soup mix to ensure they are gluten-free. Otherwise, the recipe itself is naturally gluten-free and can be easily adapted if needed.
