Ingredients for jersey mike's red pepper relish
Sweet-spicy balance starts with charred peppers and tangy vinegar—just 10 ingredients for Jersey Mike's vibes.
| Ingredient | Amount | Notes |
|---|---|---|
| Red Bell Peppers 🌶️ | 4 whole | Large, charred and peeled |
| White Vinegar 💧 | 1 cup | White or apple cider |
| Granulated Sugar 🍯 | ½ cup | White or brown sugar |
| Red Wine Vinegar 🍷 | ¼ cup | For depth of flavor |
| Cayenne Pepper 🔥 | ½ tsp | Adjust for heat preference |
| Salt 🧂 | 1 tsp | Kosher or sea salt |
| Garlic Cloves 🧄 | 2 cloves | Fresh, minced or grated |
| Red Pepper Flakes 🌶️ | 1 tsp | Optional for extra heat |
| Olive Oil 🫒 | 1 tbsp | For roasting peppers |
| Fresh Basil Leaves 🌿 | ¼ cup | Chopped, optional garnish |
The peppers are everything—roast them until blackened for that smoky depth. Grab red bell peppers from the store (they're usually the sweetest), but if you can find roasted red peppers in a jar, they're a total time-saver. Just drain them well. For the vinegar, Trader Joe's has great options, but white vinegar works perfectly fine. The sugar? Brown sugar adds a hint of molasses flavor if you're feeling fancy, but white sugar keeps it classic. Char the peppers directly over a gas flame or under a broiler—4-5 minutes per side until completely blackened.
No red wine vinegar? Extra white vinegar plus 1 tsp balsamic works in a pinch. Cayenne too spicy? Cut it to 1/4 tsp or swap for paprika. The garlic can be pre-minced from a jar (though fresh tastes better), and if you're skipping the basil, dried oregano at half the amount gives a similar vibe. Olive oil for roasting? Any neutral oil works, but extra-virgin adds a fruity note. The relish thickens as it sits—add a splash of water if it's too stiff after blending.
Store in a clean glass jar with a tight lid—keeps for 2 weeks in the fridge. The flavors actually get better after a day or two as everything melds. For parties, double the batch—this stuff disappears fast. Freezes for up to 3 months if you want to prep ahead. The basil? Toss it in right before serving so it stays fresh. Leftovers? Perfect on hot dogs, grilled cheese, or charcuterie boards—trust me, it's a game-changer.

Instructions for Jersey Mike's red pepper relish recipe
Here's how to make this addictive sweet and spicy relish that's perfect with subs, burgers, or even on its own.
Char and Peel the Red Bell Peppers
Preheat your oven's broiler to its highest setting. Place the 4 whole red bell peppers on a baking sheet and brush them generously with the 1 tablespoon olive oil. This helps create those beautiful char marks that give the relish its signature depth of flavor.
Broil the peppers for about 10-12 minutes, turning them occasionally, until their skins are completely blackened and blistered all over. You'll know they're ready when the skin looks like it's about to peel right off. The reason we char them is to develop that smoky, slightly bitter flavor that balances the sweetness perfectly.
Immediately transfer the charred peppers to a bowl and cover it tightly with plastic wrap. Let them steam for 10 minutes - this makes the skins slide right off. Peel away all the charred skin, then remove and discard the stems and seeds. You should have about 3 cups of charred pepper flesh when you're done.
Cook the Peppers with Vinegars and Seasonings
In a large saucepan, combine the charred red bell peppers, 1 cup white vinegar, 0.25 cup red wine vinegar, 0.5 cup granulated sugar, 0.5 teaspoon cayenne pepper, 1 teaspoon salt, and 1 teaspoon red pepper flakes. Bring this mixture to a boil over medium-high heat, stirring occasionally to help dissolve the sugar.
Once boiling, reduce the heat to medium-low and let it simmer uncovered for about 10 minutes. You'll see the mixture reduce slightly and the flavors meld together beautifully. This is where the magic happens - the vinegars mellow out while the sugar caramelizes just enough to create that perfect sweet-spicy balance.
After 10 minutes, add the 2 minced garlic cloves and stir them in. Cook for another 2 minutes just until the garlic is fragrant but not browned. Remove the pan from heat at this point - you don't want the garlic to burn and turn bitter.
Finish and Cool the Relish
Let the relish cool completely at room temperature. This is crucial because it allows all the flavors to fully develop and mellow out. The mixture will thicken as it cools, which is exactly what we want for that perfect spreadable consistency.
Once cooled, give the relish one final taste and adjust the seasoning if needed. You might want to add a bit more sugar if it's too tangy, or a pinch more cayenne if you want more heat. Remember, you can always adjust the heat later by adding more red pepper flakes if desired.
Transfer the relish to clean jars and refrigerate for at least 2 hours before serving. This chilling time lets all the flavors really come together. The relish will keep in the refrigerator for up to 2 weeks, making it perfect for meal prep and entertaining.
Garnish and Serve (Optional)
When ready to serve, give the relish a final stir. For that restaurant-quality presentation, sprinkle the 0.25 cup chopped fresh basil leaves on top just before serving. The bright, fresh flavor of the basil cuts through the sweetness and adds a lovely finishing touch.
This relish is incredibly versatile - spread it on subs, mix it into mayo for sandwiches, serve it as a dip with chips, or even use it as a topping for burgers. The possibilities are endless, but one thing's for sure: once you try this recipe, you'll be hooked on the perfect balance of sweet, spicy, and tangy flavors.
Pro Tips For Making Jersey Mike'S Red Pepper Relish
- CHAR THE PEPPERS: Roast the red bell peppers over a gas flame or under a broiler until the skin blackens in spots—this isn’t just for looks, it deepens the smoky sweetness that makes this relish sing. I used to stop when they were just charred; now I wait until the skin peels back easily, and the flavor jumps off the plate.
- COOL THEM FAST: Toss the roasted peppers into an ice bath for 5 minutes right after charring—this stops the cooking and makes peeling them effortless. I learned this the hard way after struggling to peel still-warm peppers, which just felt like a chore. Cold peppers slide out of their skins like butter.
- BALANCE THE VINEGARS: Use half white vinegar, half red wine vinegar—don’t skimp on the red wine. The acidity cuts through the sugar, but the fruity notes of red wine vinegar add complexity that white vinegar alone can’t match. I was skeptical until I tried it; now I double the red wine vinegar if I’m feeling fancy.
- CONTROL THE CAYENNE: Start with just a pinch of cayenne, then taste as you go—this relish should brighten, not burn. I’ve ruined batches by adding too much too soon, and the heat overpowers the sweetness. A little goes a long way; add it gradually, like seasoning steak, not like you’re in a spicy food challenge.
Creative variations of these flavors
Sweet & Smoky Grilled Version
For a deeper, smokier flavor, grill the peppers instead of roasting them. Use a gas grill set to medium-high heat and place whole peppers directly on the grates. Rotate every 3-4 minutes until fully charred and blackened—about 12-15 minutes total.
The grill's direct flame adds a campfire-like smokiness that pairs perfectly with burgers or grilled chicken. Brush the peppers with olive oil before grilling to prevent sticking and enhance charring. 🔥
Herb-Infused Variations
Swap out the basil for other fresh herbs to match different dishes. For Italian-inspired meals, try ½ cup chopped fresh oregano or thyme leaves. For a Mexican twist, add 1 tablespoon chopped cilantro and ½ teaspoon ground cumin to the relish while simmering.
These herbs brighten the relish and add complexity—perfect for tacos or nachos. I love using fresh dill for a lighter, almost Scandinavian-inspired flavor.
Spicy Heat Levels
Adjust the heat to suit your crowd by tweaking the spice blend. For mild heat, reduce cayenne to ¼ teaspoon and skip the red pepper flakes. For medium heat, use the original ½ teaspoon cayenne and add 1 teaspoon red pepper flakes.
For fiery kick, add 1 teaspoon cayenne and 1 tablespoon crushed red pepper flakes. Pro tip: Toast the spices in a dry pan for 30 seconds before adding to deepen their flavor. 🌶️
Fruit-Enhanced Twist
Add a fruity dimension by blending in ½ cup diced pineapple or peach chunks during the final cooling stage. The natural sweetness complements the vinegar and sugar beautifully, creating a tropical-inspired relish. This works especially well with pulled pork sandwiches or as a glaze for grilled chicken.
For a more robust flavor, simmer the fruit with the vinegars for 5 minutes before adding the peppers.
Low-Sugar Option
Cut the sugar in half (¼ cup) and replace the remaining ¼ cup with unsweetened applesauce or pureed roasted sweet potato. This reduces the sweetness while keeping the relish spreadable and flavorful.
The natural sweetness from the fruit or veggie balances the tangy vinegar perfectly. It’s a great option for those watching their sugar intake but still want that signature Jersey Mike’s taste. 💛
Smoky Chipotle Fusion
For a smoky, slightly smoldering flavor, add 1-2 chipotle peppers in adobo sauce (minced) to the simmering mixture. Cook for an extra 3 minutes to let the smoky chipotle flavors meld with the vinegars and sugar.
This version pairs exceptionally well with BBQ ribs or smoked meats. If you can’t find chipotles, ½ teaspoon smoked paprika adds a milder smoky note. The key is to balance the heat—adjust cayenne accordingly.

Frequently asked questions
Can I make this relish without roasting the peppers?
You can use jarred roasted red peppers as a shortcut, but fresh charred peppers give that signature smoky depth. If you skip roasting, add 1 teaspoon smoked paprika to the simmering mixture to mimic the flavor. The texture will be slightly less chunky, but still delicious.
How spicy will this relish be?
The recipe starts with medium heat thanks to cayenne and red pepper flakes. For milder heat, reduce cayenne to ¼ teaspoon and skip the flakes. For extra kick, double the cayenne and add 1 tablespoon crushed red pepper. Taste as it cools to adjust!
Can I use this relish on other foods besides subs?
It's perfect for hot dogs, burgers, grilled chicken, or as a dip for fries and chips. Try mixing 1 tablespoon into mayo for sandwiches, or drizzle it over charcuterie boards. The sweet-spicy balance works with almost any savory dish.
Why does my relish turn out too thick or too runny?
Thickness depends on cooling time—let it sit 2+ hours before adjusting. If too thick, stir in 1 teaspoon water at a time. If too runny, simmer uncovered for 5-10 extra minutes to reduce. The ideal consistency is spreadable but not watery.
Can I make this relish ahead for a party?
Yes! Make it 2-3 days ahead and store in airtight jars. Flavors actually improve with time. For parties, double the batch—it disappears fast! Freeze for up to 3 months if needed, though fresh is always best.
