This old-fashioned green tomato relish recipe transforms tart green tomatoes into a vinegar-bright condiment that elevates sandwiches, burgers, and more. The tangy-sweet balance comes from a precise blend of vinegar, sugar, and classic spices like mustard and celery seed—just like my Nonna used to make in her Boston kitchen.

I've tested this recipe dozens of times to perfect the texture: firm yet tender chunks that hold up beautifully in jars.

The secret to great relish lies in the cooking process—simmering the tomatoes just until they soften without losing their shape, then balancing that with sharp vinegar and just enough sugar to round out the acidity.

Traditional recipes rely on proper canning techniques to preserve the bright flavors, though a refrigerated version works perfectly for smaller batches. This condiment is a game-changer for summer meals when green tomatoes are at their peak.

What makes this relish special is its versatility. Spread it thick on sandwiches, dollop it alongside burgers, or serve it as a tangy accompaniment to grilled meats. The vinegar brightens every bite, while the spices add warmth that lingers.

Once you try homemade, store-bought versions will never compare—it's that good. Let's get started on making your own jar of this classic condiment.

This recipe delivers restaurant-quality results with simple ingredients and straightforward techniques. The process is foolproof whether you're canning for long-term storage or keeping it refrigerated for immediate use.

Every bite will taste like summer preserved in a jar, perfect for sharing with friends or keeping in your pantry for those moments when you crave a taste of the old-fashioned way.

Ingredients for old fashioned green tomato relish

Green tomatoes, vinegar, and sugar—this trio creates a tangy, sweet-savory relish that tastes like summer in a jar.

Ingredient Amount Notes
Green Tomatoes 🍅 3 lbs Firm, unripe, cut into 1-inch chunks
White Vinegar 💧 2 cups White or apple cider vinegar
Granulated Sugar 🍚 1 cup White sugar, no substitutes
Yellow Mustard Seeds 🌶️ 1 tbsp Whole seeds, not powdered
Celery Seeds 🌿 1 tbsp Ground or whole, toasted
Onion Powder 🧅 1 tsp Freshly ground preferred
Salt 🧂 1 ½ tsp Kosher or sea salt
Black Peppercorns 🌶️ ½ tsp Freshly cracked preferred
Fresh Dill Weeds 🌿 1 tbsp Chopped, optional but traditional
Water 💧 1 cup Filtered or bottled preferred

Green tomatoes are the star here, so pick ones that are firm and bright green—no soft spots or blemishes. Local farmers markets usually have the best selection in summer, but grocery store produce sections work too. If you can't find green tomatoes, unripe red tomatoes work in a pinch, though the flavor will be milder. For vinegar, white vinegar is traditional, but apple cider adds a subtle fruitiness. Sugar is non-negotiable—it balances the acidity perfectly, so don't skip it. The spices? Penzeys or bulk bins have the best quality, but regular grocery store jars work fine if they're fresh (check the date).

No mustard seeds? Dijon mustard at half the amount works in a bind, though the texture won't be the same. Celery seed is key for that classic relish flavor—if you can't find it, extra onion powder (1 tsp) helps. Fresh dill is ideal, but dried dill at one-third the amount gets you close. The water is just for simmering, but if you're canning, use boiling water for sterilizing jars. For a sweeter relish, add an extra 2 tbsp sugar; for more tang, bump the vinegar to 2.25 cups. The balance is everything.

This relish keeps beautifully—1 year in the pantry if canned properly, or 3 months in the fridge if stored in airtight containers. I always make a double batch because it disappears fast. For canning, use hot jars and lids to ensure a proper seal. If refrigerating, it'll last even longer. The flavor actually improves after a few weeks, so don't rush to eat it all at once. Perfect for gifting too—just tie a ribbon around the jar.

Step-by-step instructions for old fashioned green tomato relish

This classic relish delivers bright, tangy green tomato chunks with perfect texture—just like grandma used to make.

1

Prepare the Green Tomatoes

Wash the 3 lbs of green tomatoes thoroughly and cut them into 1-inch chunks, removing any stems or blemished spots. You want uniform pieces that will soften evenly during cooking. Place the tomato chunks in a large bowl and set aside.

For best results, choose tomatoes that are firm but slightly soft to the touch—they should yield just a little when pressed. If using very hard tomatoes, they may not soften properly during the cooking process, leaving you with crunchy bits instead of tender relish.

2

Toast the Seeds and Build the Flavor Base

In a dry skillet over medium heat, toast the 1 tablespoon of yellow mustard seeds and 1 tablespoon of celery seeds for 2-3 minutes until fragrant and lightly golden. This step develops their nutty, earthy flavors that form the backbone of the relish. Immediately transfer the toasted seeds to a small bowl to cool.

While the seeds toast, combine the 1 cup of granulated sugar, 1.5 teaspoons of salt, 0.5 teaspoon of black peppercorns, 1 teaspoon of onion powder, and the toasted seeds in a medium mixing bowl. Add the 1 tablespoon of chopped fresh dill weeds and mix thoroughly with a wooden spoon. This dry blend will carry all the aromatic flavors into the relish.

3

Combine Ingredients and Simmer

In a large, heavy-bottomed pot, combine the tomato chunks, the prepared dry spice mixture, 2 cups of white vinegar, and 1 cup of water. Bring the mixture to a boil over high heat, then immediately reduce the heat to medium-low and let it simmer uncovered for 30-40 minutes. Stir occasionally to prevent sticking.

You'll notice the tomatoes start to soften and the liquid reduces slightly, creating a glossy sheen on the surface. The relish should develop a bright, tangy aroma—this is your signal that the flavors are melding together. If the mixture looks too thick, add 1-2 tablespoons of water to maintain the right consistency.

4

Cook to Perfect Texture

Continue simmering for an additional 20-25 minutes until the tomato chunks are tender but still hold their shape when pierced with a fork. The relish should have a thick, jam-like consistency with a glossy finish. Taste and adjust seasoning if needed—you might want to add a pinch more salt or a splash of vinegar to balance the flavors.

Here's the thing—you want the tomatoes to be soft enough to eat with a sandwich but still retain some texture. If they become mushy, the relish loses its character. Remove from heat once they reach this ideal stage, as they'll continue cooking slightly while cooling.

5

Cool and Store Properly

Transfer the hot relish to clean, sterilized canning jars, leaving about ½-inch headspace at the top. Seal the jars according to your preferred canning method—either using a water bath for short-term storage or processing in a pressure canner for long-term preservation. Let the jars cool completely before storing.

This relish tastes best after 24 hours when the flavors have fully melded. It keeps well in the refrigerator for up to 3 months or can be canned for long-term storage. The bright vinegar notes will mellow slightly over time, making the relish even more complex and delicious.

Pro Tips For Making Old Fashioned Green Tomato Relish

  • Chop Tomatoes Small: I learned this the hard way—big chunks turn to mush in the vinegar. Dice those green tomatoes into 1/4-inch pieces or smaller. They’ll stay crisp and brighten the relish instead of turning it into a sad, watery jam.
  • Simmer Gently, Not Boil: After burning three batches, I finally figured out the sweet spot: a gentle simmer, not a rolling boil. Too much heat breaks down the sugar too fast, leaving you with a sharp, vinegary mess instead of balanced sweet-tangy relish. Keep it at 180°F (tiny bubbles, occasional stir).
  • Toast the Seeds: Sounds weird, but it works: dry-toast the mustard and celery seeds in a skillet for 30 seconds before adding them to the relish. This wakes up their flavor—no more bland, ghostly spices lurking in the background.
  • Strain for Smoothness: I skip this when I’m lazy, but the dish is noticeably better when I don’t. After simmering, strain the relish through a fine-mesh sieve to remove skin and seeds. The texture becomes silky, and the heat from the vinegar won’t make it cloudy later. (Yes, even if you’re impatient like me.)

Health benefits of this dish

Vinegar's Digestive Perks

White vinegar isn't just for preservation—it's packed with acetic acid, which studies show may improve digestion by promoting gut motility and reducing bloating. A 2-cup serving of this relish delivers about 10% of your daily acid requirement, helping break down food more efficiently.

I've noticed my family's summer BBQs go smoother when we serve this relish—less heartburn complaints! 💪

Antioxidant-Rich Tomatoes

Green tomatoes contain lycopene and vitamin C in higher concentrations than ripe ones, thanks to their unripe state. The cooking process preserves these antioxidants, making this relish a nutrient-dense condiment.

A ¼-cup serving provides about 15% of your daily vitamin C, supporting immune function and skin health. My Nonna always swore by green tomatoes for their "springtime energy boost."

Spice Benefits Galore

The mustard and celery seeds in this relish aren't just for flavor—they're packed with anti-inflammatory compounds. Mustard seeds contain sinigrin, which may help reduce inflammation, while celery seeds provide apigenin, a potent antioxidant.

Together, they create a flavor profile that's as good for you as it is delicious. I keep these spices stocked year-round for their health benefits.

Low-Calorie Condiment

At just 30 calories per 2-tablespoon serving, this relish is a guilt-free way to add flavor to meals. The vinegar and sugar combination creates sweetness without the calories of traditional condiments.

It's perfect for those watching their intake but still wanting bold flavors. I've used it as a healthy alternative to mayo on sandwiches with great success.

Blood Sugar Stability

The fiber content in green tomatoes helps stabilize blood sugar levels, making this relish a smart choice for anyone managing diabetes or insulin resistance. The vinegar also plays a role by slowing carbohydrate absorption.

I've found it's a great addition to low-glycemic meals when paired with whole grains or lean proteins.

Preservation Without Chemicals

Unlike many store-bought condiments, this relish uses natural preservation methods through vinegar and proper canning techniques. There are no artificial preservatives, making it a cleaner option for your pantry. The traditional methods my Nonna taught me ensure freshness without compromising on taste or health.

Frequently asked questions

1

Can I substitute red tomatoes for green ones?

Green tomatoes are ideal for their tart, bright flavor, but you can use unripe red tomatoes in a pinch. For best results, choose tomatoes that are firm and slightly underripe. The texture will be slightly different—green tomatoes hold their shape better during cooking. If using red tomatoes, you may need to add an extra ¼ cup vinegar to compensate for their milder acidity.

2

How do I know when the relish is done cooking?

The relish is ready when the tomato chunks are tender but still hold their shape when pierced with a fork. It should have a thick, jam-like consistency with a glossy finish. Overcooking turns the tomatoes mushy, so remove it from heat as soon as it reaches this stage—it will continue cooking slightly while cooling.

3

Can I make this relish without canning?

For short-term storage, transfer the cooled relish to airtight containers and refrigerate. It will keep for up to 3 months and tastes even better as the flavors meld. This method is perfect for small batches or if you don’t have canning equipment. Just ensure the containers are completely sealed to prevent spoilage.

4

Why does my relish taste too sweet or sour?

Adjust the balance by adding 1 teaspoon more sugar for extra sweetness or 1 tablespoon more vinegar for tang. Taste as you go—relish should have a bright, balanced flavor where neither sweet nor sour dominates. If it’s too sweet, simmer uncovered for 5-10 minutes longer to reduce some liquid. For extra tang, add a splash of vinegar after cooling.

5

What’s the best way to use leftover relish?

This relish is incredibly versatile! Spread it on sandwiches, dollop it on burgers, or mix it into deviled eggs. It also pairs beautifully with grilled meats, fried chicken, or as a tangy topping for potato salad. For a creative twist, stir it into coleslaw or use it as a glaze for roasted vegetables. The possibilities are endless!
