Roasted Red Peppers: What They Are, How to Make Them & How to Use Them
Roasted red peppers are sweet peppers that have been cooked at high heat until their skins blister and char, then peeled to reveal soft, smoky, intensely sweet flesh. Roasting transforms fresh red peppers from crisp and mildly sweet into something richer, silkier, and far more flavourful.

What Are Roasted Red Peppers?
Roasted red peppers are fully ripe red bell peppers that have been roasted using an oven, grill, flame, or air fryer. The roasting process:
- Softens the flesh
- Intensifies natural sweetness
- Adds a subtle smoky flavour
- Makes the skins easy to remove
They can be homemade or bought ready-roasted in jars.
Why Red Peppers Are Used for Roasting
Red peppers are ideal for roasting because they are:
- Fully ripe and naturally sweet
- Thick-fleshed
- High in natural sugars
- Less bitter than green peppers
Green peppers can be roasted, but they are more bitter and less sweet than red ones.
What Do Roasted Red Peppers Taste Like?
Roasted red peppers have a:
- Sweet, mellow flavour
- Soft, silky texture
- Light smoky note
- Very low bitterness
Roasting removes the sharp, raw taste of fresh peppers and replaces it with depth and richness.

Ingredients
- Red bell peppers
- Optional: olive oil
Oven Method
- Preheat oven to 220°C (200°C fan).

- Transfer peppers to a bowl and cover tightly (or place in a sealed bag).
