The Trader Joe's fire-roasted jar is the secret weapon here—look for the vibrant red and green peppers with onions in a single jar, not the pre-sliced versions. Trader Joe's carries this exact product, but if unavailable, any fire-roasted jarred peppers and onions will work. The key is selecting jars with visible char marks on the peppers, indicating proper roasting. For extra depth, I always opt for the jar with the highest pepper-to-onion ratio, as the peppers carry more concentrated smoky flavor. Fresh garlic cloves should be firm with no green shoots—Costco or local farmers markets often carry the best quality in bulk.
No fire-roasted jarred peppers? Fresh bell peppers and onions charred in a skillet with olive oil and smoked paprika will mimic the effect, though the flavor won't be identical. The vegetable broth adds umami without overpowering—Imagine or Pacific Foods brands are reliable for low-sodium options. For a quick swap, tomato paste at half the amount works in a pinch. The balsamic glaze is purely for finishing; if unavailable, a splash of red wine vinegar achieves similar brightness. Fresh herbs like parsley or basil should be vibrant green with no wilting—Whole Foods or local markets typically carry the freshest options.
This dish reheats beautifully—simply warm in a skillet with a splash of water or broth for 2-3 minutes. Store in an airtight container in the refrigerator for up to 5 days, though the flavors peak within the first 2 days. For longer storage, freeze portions in ice cube trays for up to 3 months. The caramelized onions and peppers develop even deeper flavor when reheated, making this an ideal make-ahead side for busy weeknights. Portion into single servings before freezing for effortless meal prep.

Step-by-step instructions for Trader Joe's fire roasted bell peppers and onions
Transform this pantry staple into a restaurant-worthy side dish with bold smoky depth and vibrant texture.
Sauté Garlic for Aromatic Foundation
Heat the 2 tablespoons extra-virgin olive oil in a large skillet over medium heat until shimmering but not smoking. Add the 3 cloves garlic cloves, skin-on, and sauté for 1-2 minutes until the edges turn golden and you detect toasted aroma. Remove the garlic immediately to prevent burning—this ensures sweet, nutty flavor without bitterness.
Leave the garlic in the pan for now; its infused oil will form the flavor base for the dish. The skin helps release more flavor into the oil, creating a richer foundation for the roasted vegetables. If you prefer, you can peel and chop the garlic after removing it, then return it to the pan later if desired.
Combine and Simmer the Roasted Vegetables
Pour the contents of the 1 jar Trader Joe's Fire-Roasted Bell Peppers and Onions (juices included) directly into the skillet with the garlic-infused oil. Stir to combine, then add the 0.25 cup vegetable broth. Bring to a gentle simmer over medium-low heat and cook uncovered for 8-10 minutes, stirring occasionally, until the mixture reduces slightly and the flavors meld.
You're looking for a consistency where the juices coat the back of a spoon but still maintain a loose, saucy texture. The roasted peppers and onions should soften slightly while retaining their charred edges. If the mixture appears too thick, add 1 tablespoon water to maintain the perfect balance between sauce and vegetables.
Season and Finish with Fresh Herbs
Remove the skillet from heat and stir in the 0.5 teaspoon diamond crystal kosher salt, 0.5 teaspoon red bell pepper flakes, 0.25 cup chopped fresh parsley, and 0.125 cup fresh basil leaves. Let the mixture sit off the heat for 2-3 minutes to allow the herbs to release their essential oils and infuse the dish with bright, fresh flavors.
This is where the dish comes together—salty, smoky, and vibrant. The red bell pepper flakes add subtle heat, while the fresh herbs cut through the richness of the roasted vegetables. Taste and adjust seasoning if needed, remembering that the balsamic glaze will add another layer of sweetness and acidity in the next step.
Drizzle and Serve Immediately
Return the skillet to low heat and carefully drizzle the 1 tablespoon balsamic glaze over the top, allowing it to warm through for 30-60 seconds. The glaze will glisten and slightly reduce, creating a beautiful contrast against the charred vegetables. Remove from heat immediately to prevent overcooking.
Serve the dish while still warm, garnished with an additional sprinkle of fresh parsley or basil if desired. The combination of smoky roasted vegetables, bright herbs, and sweet-tart balsamic glaze creates a dish that's perfect as a side for grilled meats, over crusty bread, or alongside roasted potatoes. The texture should be a balance of tender vegetables and slightly crisp edges, with a sauce that clings to each bite.
Pro Tips For Making Trader Joe'S Fire Roasted Bell Peppers And Onions
- DRAIN AND PAT DRY: The jarred peppers and onions come packed in liquid—skip dumping them straight into the pan. Drain, rinse with cold water, then use a paper towel to blot them dry. Wet ingredients steam instead of sear, and you’ll end up with a sad, watery mess instead of crispy, caramelized bits.
- SMASH THOSE GARLIC CLOVES: Don’t just mince the garlic—smash the whole clove with the flat side of your knife first. This releases more flavor without burning, and you’ll avoid that bitter, overcooked garlic taste that ruins the dish. Two cloves, properly smashed, make all the difference.
- SALT THE PEPPERS FIRST: Toss the drained peppers and onions with a pinch of salt before hitting the pan. This draws out excess moisture so they brown faster and develop deeper flavor. I learned this the hard way—salting after cooking just doesn’t cut it.
- TOAST THE PEPPER FLAKES: Don’t just sprinkle the red pepper flakes on top—heat them in the same pan for 10 seconds with the olive oil first. This toasts their oils and makes them smell like a campfire. The flavor jumps from "background spice" to "main event." (Yes, even if you’re impatient like me.)

Italian Pasta Sauce Base
Skip the balsamic glaze and instead stir in ½ cup crushed tomatoes and 1 teaspoon Italian seasoning during the simmering phase. This creates a quick pasta sauce perfect for tossing with linguine or penne.

Frequently asked questions
Can I use this recipe with other jarred roasted peppers?
Yes! Any jarred roasted peppers and onions will work, but Trader Joe's version has the best balance of smoky depth and natural sweetness. For a similar effect, look for brands with visible char marks on the peppers. If using fresh roasted peppers, char them in a skillet first for that authentic smoky flavor. The key is maintaining the same ratio of peppers to onions.
How do I prevent the onions from burning?
Keep the heat at medium-low and stir frequently during the 8-10 minute simmer. The vegetable broth helps regulate the heat and prevents browning. If the onions start to darken too quickly, reduce the heat slightly or add a splash of water. The goal is caramelization, not burning.
What are the best proteins to pair with this dish?
This smoky side pairs beautifully with grilled chicken, steak, or lamb. For vegetarian options, try it with roasted potatoes, crusty bread, or as a topping for grain bowls. The charred flavors complement rich meats while standing up to hearty plant-based dishes. The balsamic glaze adds a nice contrast to grilled proteins.
Can I make this ahead of time?
Store leftovers in an airtight container in the fridge for up to 5 days. The flavors actually improve overnight as the vegetables absorb the juices. For longer storage, freeze portions in ice cube trays for up to 3 months. Reheat gently in a skillet with a splash of water or broth to restore crispness.
What if I don't have balsamic glaze?
No problem! Substitute with 1 teaspoon red wine vinegar or ½ teaspoon honey mixed with a pinch of salt. Both will add sweetness and acidity to balance the smoky flavors. If you're making the Italian pasta sauce version, you won't need it at all—the tomatoes provide the acidity instead.
