This Chicago-style giardiniera recipe is the ultimate condiment with fresh peppers and veggies in oil and seasonings, an absolute must for Italian beef sandwiches!
Hot Giardiniera (Chicago-Style)
Today we're bringing you a taste of Chicago, my spicy food loving friends, with a condiment that belongs in your recipe box favorites. It's called Chicago-Style Giardiniera, and I think you're going to love it.
Patty and I were both born and raised in the Chicago area, and Chicago is well-known for its selection of beef sandwiches.
If you're from Chicago or anywhere near there, you can't order a beef sandwich without giardiniera. It's a "must try", the perfect condiment for roast beef or any type of sandwich.
You can get mild giardiniera or hot giardiniera, and I always go for the "hot".
I personally love it piled onto a hot dog or over a crispy toasted sub sandwich, and enjoy it on my pizza. We had several beef joints to choose from, and giardiniera was always on the menu. It's a must have for me, so I make homemade giardiniera all the time.
Let's talk about how to make giardiniera, Chicago style, shall we? Hot giardiniera for me!
Chicago-Style Giardiniera Ingredients
- Peppers. My recipe calls for 5 jalapeno peppers and 5 sport peppers or serrano peppers for more of a "hot giardiniera". If you'd prefer a "mild giardiniera", use 2-3 large green and/or red bell peppers instead.
- Vegetables. Use 1 cup chopped cauliflower, 2 carrots, 2 celery ribs and 1/2 to 1 cup of olives (from the jar), all thinly sliced or chopped.
- Oil (and Vinegar, if desired). Use 1 cup of good quality olive oil and 1 cup of white wine vinegar. Some Chicago style giardiniera brands use only oil. If you prefer no vinegar, replace it with water or more oil.
- Seasonings. I use lots of minced fresh garlic, dried oregano, celery seeds, crushed red pepper flakes and a touch of freshly ground black pepper.
How to Make Giardiniera (Chicago-Style) - The Recipe Method
Brine the Vegetables. To a large bowl, add peppers with cauliflower, peppers, carrots and celery. Sprinkle with salt. Cover with cold water and refrigerate for 12 hours, covered. I often brine for 24 hours.
Drain and rinse away the brine. Set aside.
Make the Giardiniera. In a separate bowl, add garlic, oregano, celery seed and ground pepper to taste. Add oil and vinegar (or water, if using) and whisk to combine.
Add to your vegetable mixture.
Add in the chopped olives and mix well.
Jar and Refrigerate. Pack the vegetables into Mason jars, ensuring the vegetables are covered with your oil mixture. You can add extra olive oil if needed to cover the mixture.
Cover and refrigerate at least 2 days before using, to allow flavors to mingle with the pickled vegetables. A week is better!
Recipe Tips & Notes
- Vinegar. Many Chicago-style brands do not include vinegar in their recipes, and instead use only oil or oil with some water. Feel free to use either. Your giardiniera will last longer in the refrigerator with vinegar, however, as vinegar is a preservative. The choice is yours.
- Other Ingredients. As the name indicates, you can use any garden fresh vegetables for this recipe. Others you might include are radishes, gherkins, olives and more.
- How Long Does Giardiniera Last? Giardiniera will keep several weeks in the refrigerator, covered, due to the acidity of the vinegar. If you use only oil, use it within 2 weeks.
- Preserving. Home canning is not recommended for recipes with oil. However, you can skip the oil and use a brine of vinegar and water. Then you can process the jars in a hot water bath of boiling water for longer keeping as long as the acidity is high enough. Shoot for 3.5 or lower pH.
- Italian Vs. Chicago-Style Giardiniera. Chicago giardiniera or "hot giardiniera" is meant to be a condiment, with more of a focus on the peppers, where Italian Giardiniera serves larger cut vegetables and is meant to be an appetizer or antipasto.
Storage Information
Store your homemade Chicago-style giardiniera in the refrigerator in sealed containers. It should last you several weeks this way.
It is normal for some types of oil to congeal in the cold. Simply bring the jar to room temperature and it will thin out again.
Best Giardiniera Peppers
Sport peppers are the traditional chili pepper that make Chicago-style giardiniera "hot". Home cooks can skip the hot peppers and use only bell peppers for the popular "mild" version.
I make homemade giardiniera frequently, though you typically need to make a larger batch, so plan accordingly. I call for jalapeno peppers in this recipe, as well as serrano peppers.
And if you REALLY want to kick this up a notch, go for the habanero pepper, or be like Mike and add in some superhots.
Yeah, baby. Bring on the heat! I know you want to, you crazy chilihead, you. I love hot giardiniera.
This is certainly Chicago at its finest, though, and won't blow your taste buds with heat. You'll get a nice kick and plenty of flavor. Enjoy!
Serving Chicago-Style Giardiniera
Chicago mild or hot giardiniera is a must for Italian beef sandwiches or roast beef, though you can serve it over any type of sandwich, hot dogs, sausages or brats, pretty much any type of sandwich or on anything off of the grill. We love it on our pizza. It truly is a wonder condiment.
Try it on my Easy Chicago-Style Italian Beef Sandwich recipe, which we love.
I also love it mixed in with lots of olives to make this amazing muffaletta sandwich. So good!
It is best served at room temperature, as the oils can congeal from refrigeration as you store it.
Patty's Perspective
It is amazing how versatile this recipe can be. You don't only have to use it for sandwiches, especially a good beef sandwich. We made some flatbread pizzas with it, and even tossed it over grilled salmon. Think of it as a vegetable sauce. Think outside the box!

Katie says
This is the second year I'm making this recipe. I made a big batch last year to use up peppers from my garden. I grew up in Chicago and relocated to Texas, and while they love their hot sauce down here, there's nothing quite like Giardiniera! I made a quadruple recipe this year to give some away. I diverged from the recipe a little bit-After I packed in the veggies, I filled each jar half way with vinegar and topped off with olive oil, because I've always liked some more tangy flavor to giardiniera.
Michael Hultquist - Chili Pepper Madness says
Awesome, Katie! I like the vinegar with my giardiniera as well. Thanks!!! Nothing like a taste of home.
Rich says
Accidentally left the brine for a day and a half. Big batch too... problem? Will it just be too salty (maybe) or not safe?
REPLY: Rich, I'm sure it's fine. -- Mike from Chili Pepper Madness.
Colleen says
Can I add fresh mushrooms to this in place of zucchini?
REPLY: Colleen, you can use mushrooms, though the consistency will change. Mushrooms get a bit mushy. I would cut them small. -- Mike from Chili Pepper Madness.
Kim says
I'm going to make this tomorrow. Prepping everything now. Do you de-seed the jalapeno?
REPLY: Kim, you don't need to de-seed them, but you can if you'd like. -- Mike from Chili Pepper Madness.
Dawn says
Do I hot bath this and for how long and how hot?
REPLY: Dawn, 10 minutes should be enough for canning. Here is a great resource for further canning information and best safety practices: http://nchfp.uga.edu/
Tina says
Thinking about doing pints or half pints for gifts! What would the proper times be for water baths?
REPLY: You should process them for 10 minutes with proper water bath techniques. -- Mike from Chili Pepper Madness.
Mike from Chili Pepper Madness says
Rachelle, yes, you can can giardiniera. Just be sure to follow proper canning procedures and ratios.
Rachelle says
This is delicious. I added a tiny bit of habanera and pepperoncini's, and omitted the zucchini and onions. Is this safe to can?
Lorelai @ Life With Lorelai says

This sounds wonderful and we have pretty much most of the ingredients growing in our garden, will book mark this for later!
eileen says
Try it on scrambled eggs and to kick up any tomato based italian dish. The stuff is magic.
Christine says
Why would you ask them to hold giardiniera? I love pickled vegetables...we live in China and pickles are a staple around here. Of course, they make them differently, but I always have pickled something in the fridge;) I'd love to try these!
Michelle @ A Dish of Daily Life says
This is totally up my alley!! I'I think I have had something similar with big chunks of veggies as an appetizer at a local restaurant and was planning to try to make my own this summer. I'll try yours too...it looks like it will be fabulous on sandwiches!
