Soups & Stews
This old-fashioned sweet tomato relish recipe brings back the homestyle chunkiness that disappeared from grocery shelves decades ago. The perfect balance of sweet, tangy, and slightly spiced flavors makes it a condiment that elevates everything from sandwiches to cheese platters.
I developed this version after years of testing, ensuring the texture stays gloriously chunky while the sugar and vinegar work together to create that signature tang-sweet harmony.

Unlike store-bought versions that often taste artificial, this recipe uses real ingredients cooked down until the tomatoes break into perfect, bite-sized pieces.
The slow simmer process allows all the flavors to meld together, resulting in a relish that's sweet enough to satisfy but never cloying.

Ingredients for old fashioned sweet tomato relish
Ten ingredients transform fresh tomatoes into nostalgic, chunky sweetness that jars beautifully.
| Ingredient | Amount | Notes |
|---|---|---|
| Fresh Tomatoes 🍅 | 6 lb | Roma or paste tomatoes preferred |
| Yellow Onions 🧅 | 1 whole | Medium size, finely chopped |
| Granulated Sugar 🍚 | 3 cups | White or light brown preferred |
| White Vinegar 💧 | 1 ½ cups | Distilled or apple cider vinegar |
| Mustard Seeds 🌶️ | 1 ½ tsp | Whole seeds, lightly crushed |
| Celery Seeds 🌿 | 1 tsp | Freshly ground preferred |
| Ground Allspice 🌶️ | ½ tsp | Freshly ground for best flavor |
| Salt 🧂 | 1 ½ tsp | Diamond Crystal kosher preferred |
| Extra-Virgin Olive Oil 🫒 | ¼ cup | For finishing drizzle |
| Fresh Parsley 🌿 | ¼ cup | Finely chopped, for garnish |
The tomatoes are the heart of this relish—Roma or paste tomatoes break down perfectly for that classic chunky texture. Local farmers markets often have the best quality in summer, but grocery store Roma tomatoes work too. Avoid vine-ripened varieties—they're too watery. The onions should be sweet and yellow, not bitter or red. Yellow onions from the produce section (not the onion blend bags) give that authentic old-fashioned flavor. For the spices, Penzeys or bulk bins are worth the investment—freshly ground spices make all the difference in this recipe where every layer of flavor matters.
No Roma tomatoes? Regular slicing tomatoes work in a pinch, but you'll need to peel and core them first. The vinegar can be swapped for apple cider vinegar if you prefer a fruitier tang. Running short on mustard seeds? Dijon mustard at half the amount adds depth, though it changes the texture slightly. The sugar can be light brown if you want a deeper caramel note, but white sugar keeps the relish bright and clean. For storage, glass canning jars are ideal—they preserve the color and keep the relish fresh for months. If you're in a hurry, ball mason jars are the gold standard for canning.
This relish tastes even better after a few days as the flavors meld together. Store in sterilized jars in the refrigerator for up to 6 months, or can it for long-term storage. The texture stays gloriously chunky if you don't overcook it—simmer just until the tomatoes break down, not until they're mushy. For gift-giving, portion into small jars with a sprig of parsley on top. The olive oil finishing drizzle isn't just for flavor—it creates a beautiful sheen and keeps the relish moist. Make a double batch; you'll want to share this with everyone.

Instructions for old fashioned sweet tomato relish
Transform fresh garden tomatoes into a vibrant, chunky relish that captures summer's essence in every jar.
Prepare and Cook the Tomato-Onion Base
Begin by washing the 6 lb of fresh tomatoes thoroughly, then cut them into quarters and remove the cores. Place them in a large stockpot and add the whole yellow onion, chopped into ½-inch pieces. This onion-tomato combination forms the heart of your relish, so don't skip the chopping—you want those onion pieces to remain visible and tender.
Bring the mixture to a boil over medium-high heat, then reduce to a gentle simmer. Let it cook uncovered for 20-25 minutes, stirring occasionally, until the tomatoes break down into a thick, chunky consistency. You'll know it's ready when the mixture reduces significantly and the tomatoes release their juices freely. The onions should soften but remain distinct pieces—this texture is essential for that classic old-fashioned texture.
Add Spices and Sweeteners for Depth
While the tomato mixture simmers, lightly crush the 1.5 teaspoons of mustard seeds between two spoons or in a mortar and pestle—just enough to break their outer shells while keeping some texture. Add these to the pot along with the 1 teaspoon of celery seeds, 0.5 teaspoon of ground allspice, and 1.5 teaspoons of salt. Stir everything together and let it cook for another 5 minutes to allow the spices to bloom and infuse their flavors.
Next, gradually whisk in the 3 cups of granulated sugar while stirring continuously to dissolve it completely. This step is crucial—adding sugar too quickly can cause clumping. The mixture should begin to thicken noticeably as the sugar integrates. Taste a small spoonful at this stage; the balance of sweetness and acidity should be harmonious, though you'll adjust this further in the next step.
Incorporate Vinegar and Finish Cooking
Pour in the 1.5 cups of white vinegar slowly, stirring constantly to distribute it evenly. The vinegar will help preserve the relish and brighten the flavors. Return the heat to medium and let the mixture simmer for an additional 15-20 minutes, stirring occasionally. The relish should now be thick, glossy, and deeply aromatic with a perfect balance of sweet, tangy, and spicy notes.
To test for doneness, place a small spoonful on a chilled plate. If it holds its shape without running and has a gel-like consistency, your relish is ready. The color should be a rich, deep red with visible tomato chunks and onion pieces—this is the hallmark of a well-made old-fashioned relish. If it's still too thin, simmer uncovered for another 5 minutes to reduce further.
Cool, Jar, and Finish
Remove the pot from heat and let the relish cool to room temperature, stirring occasionally to prevent skin formation. Once cooled, stir in the 0.25 cup of extra-virgin olive oil and the 0.25 cup of finely chopped fresh parsley. The oil adds a luxurious finish, while the parsley brings a fresh, herbaceous note that cuts through the sweetness.
Ladle the relish into sterilized canning jars, leaving about ½-inch headspace at the top. Seal the jars according to manufacturer instructions, then process in a boiling water bath for 10 minutes to ensure proper preservation. Let the jars cool completely before storing in a pantry. This relish will keep for up to a year, making it the perfect homemade pantry staple for sandwiches, hot dogs, or as a topping for grilled meats.
Pro Tips For Making Old Fashioned Sweet Tomato Relish
- CHAR THE ONIONS: Cook the onions until they’re deep golden—almost caramelized—before adding tomatoes. I used to rush this, but stopping just shy of browning keeps the relish from tasting bitter. A splash of water at the end helps dissolve the sugar better, too.
- GRATE THE TOMATOES: Skip the chopping—grate the tomatoes instead. It breaks them down evenly, speeds up cooking, and prevents a chunky texture. (Yes, even if you’re impatient like me.) Just drain them well afterward to avoid a watery relish.
- SALT THE VINEGAR: Add a pinch of salt to the vinegar before mixing it in. It balances the sharpness and rounds out the flavor—trust me, it makes a real difference. I learned this the hard way after making a batch that tasted too tangy.
- SIMMER GENTLY: Keep the heat low after adding sugar—high heat can make the relish grainy. A slow simmer for 20-25 minutes lets the sugar dissolve smoothly. Stir occasionally, but don’t obsess; it’s not a stir-fry.
Wine and beer pairings for this recipe
White Wine Pairings
For this sweet tomato relish, a crisp Sauvignon Blanc from New Zealand or Loire Valley is my go-to choice. The wine's bright acidity and citrus notes cut through the relish's sweetness while complementing its herbal undertones from the celery and allspice.
I especially love Cloudy Bay Sauvignon Blanc—its zesty lime and passionfruit flavors create a perfect balance with the relish's tangy-sweet profile. 🍷
Dry Riesling Harmony
A dry Riesling from Germany's Mosel region offers an elegant pairing that highlights the relish's complexity. The wine's mineral-driven acidity and subtle petrichor notes enhance the tomato's natural sweetness without overpowering the spices.
Look for Dr. Loosen Blue Slate Riesling—its precise balance of fruit and mineral makes it an ideal companion for this condiment.
Light Lager Balance
For beer lovers, a crisp American lager like Budweiser or Coors Banquet provides the perfect neutral canvas. The light malt sweetness and subtle hop bitterness allow the relish's flavors to shine while providing a refreshing contrast.
Serve slightly chilled to enhance the refreshing quality that pairs beautifully with the relish's warmth. 🍺
Spiced Rum Cocktail
Transform your relish into a cocktail by mixing 2 oz dark spiced rum (I recommend Kraken Black Spiced Rum) with 1 oz relish and a splash of ginger beer. The rum's molasses notes amplify the relish's sweetness while the ginger beer's spice echoes the allspice in the recipe.
Serve over crushed ice for a refreshing summer drink that's perfect for backyard gatherings.
Cider Pairing Potential
A dry hard cider like Angry Orchard Crisp Apple brings out the relish's fruity undertones while its slight tartness balances the sweetness. The apple notes in the cider complement the tomato's natural sweetness, creating a harmonious pairing that feels both classic and unexpected.
This combination works beautifully with charcuterie boards featuring the relish.
Seasonal Adaptations
For fall and winter, switch to a Chardonnay with oak notes—like Meiomi Pinot Noir (yes, it's a Chardonnay!)—to complement the relish's deeper flavors when paired with hearty dishes. The wine's buttery richness contrasts beautifully with the relish's tangy sweetness, making it ideal for holiday meals.
The oak's vanilla undertones also echo the subtle caramel notes from the sugar in the relish. 🍇

Frequently asked questions
Can I use canned tomatoes instead of fresh for this relish?
Fresh tomatoes give the best texture and flavor, but you can use 28 oz canned crushed tomatoes in a pinch. Drain them well first, then proceed with the recipe. The texture will be slightly softer since canned tomatoes have more moisture. For extra chunkiness, add ½ cup diced fresh tomatoes to the mix before simmering.
How do I adjust the sweetness if I prefer it less sugary?
Start with 2.5 cups sugar instead of 3, then taste as you go. You can always add more sugar later if needed, but you can't remove excess sugar once it's cooked in. For a more tangy profile, increase the vinegar by ¼ cup and reduce sugar by ½ cup. The key is balancing sweetness with the vinegar's acidity.
What's the best way to store homemade relish without canning?
Transfer the cooled relish to sterilized glass jars and refrigerate for up to 6 months. For longer storage, freeze in airtight containers or freezer bags for up to 1 year. Thaw overnight in the fridge before using. The texture may soften slightly after freezing, but it remains delicious.
Why did my relish turn out too thin?
This usually happens from overcooking or not enough simmering time. For a thicker texture, simmer uncovered for 5-10 extra minutes to reduce liquid. You can also stir in 1 tablespoon cornstarch mixed with 1 tablespoon water and cook for 2 more minutes until thickened. The relish should hold its shape when spooned onto a plate.
Can I make this relish without vinegar?
Vinegar is essential for preservation and tangy flavor, but you can substitute with lemon juice at the same amount. For every 1 cup vinegar, use 1 cup fresh lemon juice. Keep in mind the relish will have a shorter shelf life (about 3 months refrigerated) and may not preserve as well for canning.
