The roasting time for sweet peppers depends on how they are prepared and the size of the pieces. Generally, you should preheat your oven to 400°F (200°C) to achieve the best results.
If you are roasting sliced peppers tossed with olive oil, salt, and seasoning, place them in a single layer on a lined sheet pan. Bake them for 25 to 35 minutes until they become soft. If you prefer to roast them cut-side up with olive oil, salt, garlic, and balsamic vinegar, they will typically take 20 to 25 minutes to become tender and slightly charred.
For mini sweet peppers, you can roast them whole or sliced into rounds or strips after removing the seeds and flesh. After tossing them with olive oil, salt, and pepper, they generally require about 20 minutes in the oven.
Roasting is an excellent method because it caramelizes the natural sugars in the peppers. This process intensifies their sweetness and reduces bitterness, creating a smoky flavor and a tender texture perfect for salads, salsas, or sauces.
