Ingredients You'll Need

A clear glass jar filled with small, cubed pieces of yellow potato and red pepper mixed with some green herbs, all soaked in a light, yellowish liquid. The jar has a metal lid and is sitting on a rough, dark surface. The potato pieces are the main parts, with colorful red bits spread throughout, making the jar look vibrant and fresh. photo taken with an iphone --ar 4:5 --v 7

The beauty of this recipe lies in its simplicity and how each ingredient plays a crucial role in building the complex flavors and vibrant colors that make this relish shine.

10 cups chopped zucchini: The base of the relish, providing fresh crunch and mild flavor that balances the other ingredients.
4 cups chopped onion: Adds sweetness and depth with a little bit of bite that complements the vegetables beautifully.
1 red bell pepper, chopped: Brings a bright, sweet flavor and a pop of color to the mixture.
1 yellow bell pepper, chopped: Adds sweetness and brightness to balance the red pepper and zucchini.
¼ cup kosher salt: Essential for drawing out moisture and softening the vegetables while enhancing their natural flavors.
4 cups white sugar: Provides the perfect amount of sweetness to balance the vinegar’s acidity.
2 ½ cups apple cider vinegar: Adds tang and preserves the relish, contributing a subtle fruitiness.
1 tablespoon cornstarch: Helps thicken the relish to a luscious, spreadable texture.
2 teaspoons celery seeds: Offers a subtle, earthy flavor that lifts the overall taste profile.
1 teaspoon ground turmeric: Adds a lovely golden hue and a mild, warm spice.

Directions

Step 1: Toss the chopped zucchini, onion, and bell peppers with the kosher salt in a large bowl. I like to combine them really well so the salt is evenly distributed. Set this mixture aside for 8 hours; this step is key for drawing out excess moisture and concentrating flavors.

Step 2: After the resting period, thoroughly rinse the zucchini mixture under cold water to remove the salt. Drain it well using a colander or clean kitchen towel to remove as much water as possible before cooking.

Step 3: Transfer the drained vegetables to a large pot. Stir in the white sugar, apple cider vinegar, cornstarch, celery seeds, and turmeric. I find it helps to whisk the dry ingredients first to avoid lumps and create a smooth base for cooking.

Step 4: Cook the mixture over medium heat, stirring frequently to prevent sticking, until it thickens nicely. This usually takes about 50 minutes. You’ll notice the relish becoming glossy and the vegetables softening while still holding a slight bite.

Step 5: While the relish is cooking, inspect your jars and lids carefully. Discard any jars with cracks or rusted rings. Place the jars in simmering water for at least 5 minutes to sterilize, and wash new lids and rings in warm, soapy water, then rinse thoroughly.

Step 6: Once the relish is ready, pack it tightly into the hot sterilized jars, filling them to within ¼ inch of the top. Run a clean knife or thin spatula around the inside edges to remove any trapped air bubbles, then wipe the rims clean with a moist paper towel.

Step 7: Place the lids on the jars and screw on the rings just firmly enough to hold the lids in place without being too tight. Prepare a large stockpot with a rack and fill it halfway with water. Bring to a boil.

Step 8: Using a jar lifter or tongs, carefully lower the jars into the boiling water, arranging them 2 inches apart. Add more boiling water if needed, so the jars are covered by at least 1 inch of water. Cover the pot and process the jars for 30 minutes.

Step 9: Remove jars with tongs and place them on a wooden or cloth-covered surface, spaced several inches apart. Let them cool completely for several hours. Once cool, press the centers of the lids to confirm they have sealed (there should be no movement). Remove the screw bands and store the jars in a cool, dark area.

Servings and Timing

This recipe yields about 6 pints of zucchini relish, which typically translates to around 96 small serving spoonfuls — perfect for sharing or gifting. Preparation time comes to about 35 minutes, but remember, the vegetables need to rest with salt for 8 hours, so plan ahead. Cooking takes around 1 hour and 30 minutes, with a total time commitment of just over 10 hours due to the resting and cooling stages. The actual hands-on work is minimal, making this a relaxing yet rewarding kitchen project.

How to Serve This Zucchini Relish with Sweet Peppers Recipe

I love serving this homemade relish chilled or at room temperature because it really lets those fresh, bright flavors shine. It’s a fantastic topping for hot dogs and burgers, transforming a simple meal into something special. If you’re feeling adventurous, spoon some over grilled chicken or fish for a burst of color and tang.

For garnishing, I often sprinkle a few extra celery seeds on top when plating to echo that unique flavor note from inside the relish. Presentation-wise, I find serving it in a small, pretty bowl alongside sliced breads or crackers makes it inviting and fun for parties or casual nights in.

When it comes to beverages, this relish pairs wonderfully with a crisp white wine like Sauvignon Blanc or a light-bodied rosé. For non-alcoholic options, a sparkling lemonade or iced tea complements the sweet and tangy notes perfectly. I keep it on hand for summer barbecues, holiday feasts, and as a delightful surprise for weekday sandwiches alike.

Variations

Over time, I’ve tried some fun twists on this Zucchini Relish with Sweet Peppers Recipe that you might enjoy. For a little extra heat, I sometimes add finely chopped jalapeños or a pinch of cayenne pepper—it adds just the right kick without overwhelming the sweet flavors.

If you’re aiming for gluten-free or vegan-friendly, you’re already set, as this recipe uses naturally gluten-free ingredients and contains no animal products. For a lower sugar version, I reduce the white sugar slightly and replace part of it with natural sweeteners like honey or maple syrup, though I keep the vinegar balance to preserve that classic tang.

Sometimes, I also experiment with roasting the peppers before adding them to the mix. It adds a smoky depth that’s incredible if you want a more complex flavor. You can also try slow cooking the mixture in a crockpot on low for several hours to let flavors meld more slowly.

Storage and Reheating

Storing Leftovers

Once opened, I keep the relish refrigerated in airtight containers or back in the sterilized jar with a tight lid. It stays fresh for about 3 to 4 weeks in the fridge. Using glass jars with secure lids helps maintain flavor and keeps the relish crisp and vibrant.

Freezing

I don’t usually freeze this relish because freezing can change the texture of the cooked vegetables, making them softer and less crisp when thawed. However, if you want to freeze it, use freezer-safe containers, leaving some headspace for expansion. It should keep well for up to 3 months but expect some texture changes upon thawing.

Reheating

This relish is best enjoyed cold or at room temperature, so I typically don’t reheat it. If you prefer it warm, gently heat just enough for serving in a saucepan over low heat, stirring occasionally to prevent scorching. Avoid microwaving to maintain the best texture and flavor.

FAQs

Can I use other types of peppers in this zucchini relish?

Absolutely! While the recipe calls for red and yellow bell peppers for their sweetness and color, you can substitute with orange bell peppers or even add a bit of green bell pepper for a slightly different flavor. Just keep in mind that green peppers are less sweet, so they’ll alter the final taste a bit.

Do I need to peel the zucchini or peppers before chopping?

No peeling is necessary. The skin of zucchini and bell peppers is tender and full of nutrients, plus it helps add texture and color to the relish. Just wash them thoroughly before chopping to ensure they’re clean and ready.

How can I tell if my jars are properly sealed after processing?

Once the jars are cooled, press down in the center of each lid with your fingertip. If the lid doesn’t pop up or move, the jar has sealed properly. You can also gently lift the jar by the lid—if it stays firmly attached, you’re good. If not, refrigerate and use the relish within a week.

Can I make this relish without waiting the full 8 hours for salting?

The 8-hour salting step is important because it draws out moisture and softens the vegetables while enhancing flavor. Skipping or shortening it can result in a watery or less flavorful relish. If time is tight, at least 4-6 hours will help, but overnight is best for optimum taste and texture.

What dishes pair well with zucchini relish besides sandwiches?

I love adding this relish to grilled meats like chicken or pork, serving it as a vibrant side with roasted vegetables, or even mixing it into potato or pasta salad for an extra zing. It also works great as a topping for flatbreads or a condiment alongside cheese and charcuterie boards.
