Portuguese-Style Olive Oil Roasted Vegetables
Why this recipe works
- Simple, layered flavour: Olive oil, garlic and sweet paprika coat the vegetables before roasting, giving them a savoury base without needing a long ingredient list.
- Fresh finish: Lemon juice cuts through the richness of the olive oil and lifts the natural sweetness of the roasted vegetables.
- Easy to serve: The vegetables work warm, at room temperature or reheated, making them useful alongside fish, meat, grains or simple vegetarian meals.

Texture tips
- Use a hot tray: Preheating the baking tray helps the vegetables start roasting as soon as they hit the surface, encouraging better colour on the edges.
- Avoid crowding: Spread the vegetables in a single layer with space between pieces so moisture can evaporate rather than steam them soft.
Ingredient notes
- Paprika choice: Sweet paprika keeps the flavour rounded and mellow; smoked paprika gives the dish a deeper, more pronounced smoky note.
- Cut evenly: Chunky, similar-sized pieces help the pepper, courgette and onion cook at the same rate.
Make-ahead tips
- Prep in advance: The vegetables can be cut ahead and kept chilled, then tossed with the seasoned oil just before roasting.
- Reheat for best texture: Reheat on a baking tray at 200°C (390°F) until piping hot, rather than microwaving, to help restore some roasted texture.
- Freezer-friendly: Cool completely before freezing, then thaw overnight in the fridge and reheat thoroughly before serving.

Ingredients
Instructions
- Heat the oven to 220°C (430°F) and set a large baking tray inside to preheat. Peel and finely slice the garlic. Cut the red peppers, courgettes and red onion into chunky, bite-sized pieces so they roast evenly.
- In a mixing bowl, stir together the olive oil, garlic, sweet paprika, fine sea salt and black pepper. Add the vegetables and toss until everything is well coated. Carefully tip onto the hot tray and spread into a single layer.
- Roast for 30 minutes, turning once halfway through, until tender with lightly caramelised edges. If the tray looks crowded, spread the vegetables out more so they roast rather than steam. While they roast, finely chop the fresh parsley and juice the lemon.
- Transfer the vegetables to a serving dish and squeeze over the lemon juice. Scatter with the parsley and toss gently. Taste and adjust with a pinch more fine sea salt and black pepper if needed.
Recipe notes
Tips
- For deeper caramelisation, keep the vegetables in a single layer with a little space between pieces, and use the hottest part of the oven.
- If you are serving this with roast meats or fish, roast the vegetables on the top shelf for the last 10 minutes to pick up extra colour.
- If you are cooking for anyone vulnerable to foodborne illness, make sure the vegetables are roasted until piping hot throughout.
Substitutions
- Replace sweet paprika with smoked paprika for a more pronounced smoky flavour.
- Replace lemon with lime for a sharper, more tropical finish.
- Replace fresh parsley with fresh coriander for a different herbal note.
Storage
- Refrigerate up to 4 days
- Cool completely, then refrigerate in a sealed container. Reheat on a baking tray at 200°C (390°F) for 10 to 15 minutes until piping hot, or enjoy at room temperature; freeze for up to 2 months and thaw overnight in the fridge before reheating.
