Ingredients for red bell pepper relish
Ten simple ingredients transform vibrant peppers into a sweet-tangy relish perfect for charcuterie and sandwiches.
| Ingredient | Amount | Notes |
|---|---|---|
| Red Bell Peppers 🌶️ | 2 cups | Diced, roughly 1-inch pieces |
| Yellow Onion 🧅 | 1 whole | Diced, medium size preferred |
| Garlic Cloves 🧄 | 3 cloves | Minced, fresh preferred |
| Apple Cider Vinegar 🍎 | ½ cup | Raw and unfiltered preferred |
| Granulated Sugar 🍚 | ¼ cup | Light brown sugar for depth |
| Fresh Dill 🌿 | ¼ cup | Chopped, stems removed |
| Fresh Parsley 🌿 | ¼ cup | Chopped, flat-leaf preferred |
| Olive Oil 🫒 | ¼ cup | Extra-virgin, for richness |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground preferred |
The red bell peppers are the star—look for firm, vibrant ones at the grocery store, ideally with a glossy sheen. Trader Joe's and local farmers markets often carry the sweetest varieties. Avoid peppers with soft spots or wrinkled skin, as they won't hold up well during cooking. The yellow onion should be crisp and white inside, not starting to sprout. For garlic, fresh cloves are non-negotiable—pre-minced jars lack the depth. If you're short on fresh herbs, dried dill and parsley work at one-third the amount, but the texture won't be as bright.
No apple cider vinegar? White vinegar or balsamic vinegar both work, though the flavor profile shifts slightly. Swap granulated sugar for honey or maple syrup—just reduce the liquid in the recipe by 2 tablespoons to account for the extra moisture. The olive oil can be omitted if you're watching calories, but it adds a lovely richness that balances the acidity. For a smoky twist, add 1/2 teaspoon smoked paprika with the black pepper. If you're making this ahead, the relish actually improves after 24 hours as the flavors meld.
This relish keeps beautifully in an airtight container in the fridge for up to 3 weeks. The flavors deepen over time, so it's worth making a batch and letting it sit. For longer storage, transfer to a sterilized jar and process in a water bath for 10 minutes to can it safely. I like to portion it into small jars—perfect for gifts or quick meals. The texture remains chunky and fresh, unlike many store-bought relishes that turn mushy.

Step-by-step instructions for red bell pepper relish
This bright, sweet-tangy relish comes together in minutes with simple techniques that maximize flavor.
Sauté the Vegetables Until Tender
Heat the olive oil in a large skillet over medium heat. Add the diced yellow onion and cook for 5 minutes until softened and translucent. This foundational step builds flavor through caramelization - don't rush it. Add the diced red bell peppers and continue cooking for another 5 minutes until they begin to soften slightly but still maintain their shape.
When the vegetables are just beginning to release their juices, add the minced garlic cloves and stir for 30 seconds until fragrant. The garlic should sizzle gently without browning - this indicates perfect timing. Remove the skillet from heat at this point to prevent the garlic from burning, which would make the relish bitter.
Combine Wet and Dry Ingredients
Return the skillet to medium-low heat and add the apple cider vinegar, stirring to deglaze the pan and scrape up any browned bits from the bottom. These flavorful bits are essential for depth. Add the granulated sugar and stir until completely dissolved, about 1 minute. This creates the perfect balance of sweetness that will develop as the relish cools.
Remove the skillet from heat again and let it cool for 5 minutes. This cooling period prevents the herbs from wilting in hot oil. Stir in the chopped fresh dill and parsley, along with the salt and black pepper. The herbs should be evenly distributed throughout the mixture - this is where the relish gets its fresh, bright character.
Simmer and Thicken the Relish
Return the skillet to low heat and bring the mixture to a gentle simmer. Let it cook uncovered for 10-12 minutes, stirring occasionally. You're looking for the relish to thicken slightly as the liquid reduces. The texture should be slightly syrupy but still pourable - it will continue thickening as it cools.
Taste the relish and adjust seasoning if needed. You may need to add a pinch more salt or sugar depending on your preference. The relish should have a perfect balance of sweet, tangy, and slightly savory flavors. Remove from heat immediately when it reaches your desired consistency - overcooking will make it too thick.
Cool and Store for Maximum Flavor
Transfer the relish to a clean glass jar and let it cool completely at room temperature. This cooling process allows all the flavors to meld together perfectly. The relish will thicken significantly as it cools - this is normal and actually enhances the texture.
Once completely cooled, seal the jar and refrigerate for at least 2 hours before serving. This resting period develops the flavors even more. The relish will keep in the refrigerator for up to 2 weeks, making it perfect for gifting or meal prep. The longer it sits, the more complex and delicious it becomes.
Pro Tips For Making Red Bell Pepper Relish
- Char the Peppers Right: Roast the red bell peppers over a gas flame (or under a broiler) until the skin blackens in spots—this isn’t about even color, it’s about deep, smoky flavor. I learned this the hard way by peeling them too soon; let the char develop for 3-4 minutes per side, then seal them in a bowl for 10 minutes to steam off the skin.
- Slice Onions Thinly: Cut the yellow onion into paper-thin slices—no thick rounds. The goal is for them to soften quickly without turning mushy; if you’re impatient like me, a mandoline makes this step worth it. Thin slices also caramelize faster, giving that sweet, jammy texture the relish needs.
- Balance Vinegar and Sugar: Taste the raw mix before cooking—if the vinegar tastes sharp, add sugar gradually (start with half the recipe’s amount). The relish should finish with a bright tang, not a pucker. I once overdid the vinegar and had to salvage it with extra sugar; better to adjust now than later.
- Simmer Until Thick: Reduce the relish on medium-low heat until it coats the back of a spoon—this takes 15-20 minutes, not 5. Skipping this step leaves you with a watery mess. Stir occasionally and resist the urge to rush; patience here makes the difference between relish and sad, thin chutney.
Storing and reheating this red bell pepper relish
Refrigerator Storage
Store your red bell pepper relish in an airtight glass container—I prefer mason jars for their durability and airtight seals. Keep it refrigerated at 40°F or below for up to 3 weeks, though I’ve found it tastes even better after 24 hours as the flavors meld.
The chunky texture stays intact, unlike many store-bought relishes that turn mushy. 🌿
Freezing for Long-Term Use
For extended storage, portion the relish into small glass jars (like 4-ounce sizes) and freeze for up to 3 months. Leave ½-inch headspace to prevent expansion cracks.
Thaw overnight in the fridge—never microwave it directly, as this can make the peppers soggy. The texture remains vibrant when reheated gently on the stovetop. ❄️
Can for Gifting
For a showstopping gift, sterilize jars and process the relish in a water bath for 10 minutes. This preserves it for 6-12 months on the shelf.
I love labeling jars with the date and recipe name—it’s a conversation starter at holiday gatherings. The sterilization process locks in the bright, tangy flavor perfectly. 🎁
Reheating Safely
If you’ve refrigerated the relish, reheat it gently on the stovetop over low heat for 3-5 minutes, stirring occasionally. Avoid high heat, which can break down the peppers’ texture. For microwave reheating, use 30-second intervals on low power—just enough to warm through without losing the chunky appeal. 🔥
Preserving Freshness
Always use a clean spoon when scooping from the jar to prevent bacterial contamination. If the relish develops an off smell or slimy texture, discard it—never risk foodborne illness. The acidity from vinegar helps preserve it, but proper storage is key.
I keep a small jar in my fridge for quick access and portion larger batches into individual servings. 💡
Flavor Development Tips
The relish tastes best after 24 hours in the fridge, as the flavors deepen. For extra vibrancy, add a dash of fresh dill or parsley just before serving. If it thickens too much, stir in 1 teaspoon of water or vinegar to restore the perfect pourable consistency.
This simple adjustment keeps it versatile for sandwiches or dipping. ✨

Frequently asked questions
Can I use other bell pepper colors in this relish?
Yellow or orange bell peppers work beautifully—they'll give your relish a slightly different color profile (lighter and brighter) while keeping the same sweet-tangy flavor. For a more complex taste, mix colors or add 1/2 cup of green bell peppers (they're milder and hold their shape well). Just adjust cooking time by 1-2 minutes if using greens, as they're less tender.
How do I prevent the relish from getting too watery?
The key is simmering time and ingredient ratios. If your relish is too thin, reduce the apple cider vinegar by 1 tablespoon or simmer uncovered for an extra 2-3 minutes to evaporate excess liquid. For future batches, try adding 1/2 teaspoon of cornstarch mixed with 1 teaspoon water at the end—stir it in and cook for 1 minute to thicken naturally.
What are the best ways to use this relish beyond sandwiches?
This versatile relish shines on charcuterie boards as a dip for crackers or veggies, as a topping for grilled chicken or fish, or mixed into hummus or tzatziki for extra depth. Try it as a glaze for roasted potatoes (brush on before baking) or as a filling for stuffed mushrooms. The sweet-tangy balance also works well in cocktails—add 1 teaspoon to a Bloody Mary or margarita for a peppery kick.
Can I make this relish without vinegar?
While vinegar is traditional for preservation and tang, you can substitute with lemon juice (use 1/4 cup plus 1/2 teaspoon citric acid for preservation) or white wine (reduce other liquids by 2 tablespoons). However, the relish will have a shorter shelf life (1 week refrigerated) and may not thicken as well. For a fermented version, replace vinegar with 1/2 cup brine from pickles and ferment for 3-5 days—this creates a probiotic-rich relish with a tangy, funky flavor.
Why did my relish turn out too sweet or too sour?
Adjustments are easy! If it's too sweet, balance it with 1 extra tablespoon of vinegar and let it sit 30 minutes before tasting again. For overly sour relish, stir in 1 teaspoon honey or maple syrup and simmer for 1 minute to blend flavors. Pro tip: Taste as you go—after adding vinegar and before adding sugar. The relish should have a 60/40 sweet-to-tangy ratio when cool. If you're unsure, start with slightly less sugar (1/4 cup) and adjust to taste.
