These roasted garlicky sweet peppers and chillies are a masterclass in slow-cooked flavour. By gently roasting the peppers in plenty of olive oil at a lower temperature, they transform into something incredibly tender and jammy. The addition of fresh garlic and a variety of red chillies provides a sophisticated heat that complements the natural sweetness of the peppers without the need for added syrups or heavy glazes.

This vibrant low-sugar dish is a versatile addition to your culinary repertoire, working beautifully as part of a Mediterranean antipasti platter or served alongside grilled meats and fish. Because the flavours develop further over time, it is an excellent make-ahead option for weekend entertaining. Simply store the peppers in their aromatic oil and bring them to room temperature before serving to allow the flavours to shine.

Ingredients for Roasted Garlicky Sweet Peppers and Chillies

  • 230g red chillies (such as cayenne, Fresno, or jalapeño), halved lengthwise, seeds removed if desired

How to make Roasted Garlicky Sweet Peppers and Chillies

Preheat oven to 149°C. Toss sweet peppers, chillies, garlic, oil, and sugar in a large baking dish; season with salt and black pepper.

Roast peppers and chillies, tossing every 30 minutes or so, until they are completely softened and starting to caramelize in spots, 2–2 1/2 hours. Let cool, then add vinegar and toss to combine.

Peppers and chillies can be roasted 1 week ahead. Cover and chill. Bring to room temperature before serving.
