Portuguese Baked Vegetables with Herb Butter and Olive Oil
Mixed Portuguese-style roasted vegetables finished with a fresh herb butter for extra richness.
About This Recipe
Portuguese cooking makes heavy use of simply roasted or baked vegetables -- peppers, onions, and potatoes cooked slowly until soft and lightly caramelized, seasoned with little more than olive oil, garlic, and bay leaf. This version adds a finishing herb butter, melted over the vegetables right out of the oven, for extra richness against the dish's inherently simple, rustic character. The technique centers on giving the vegetables enough time and oven heat to properly caramelize rather than just steam -- a hot oven, around 200°C (400°F), and enough space on the pan are what create browned, sweet edges instead of pale, soft vegetables. Tossing everything in olive oil generously before roasting, and adding a whole bay leaf or two for aromatic depth, are small details that matter more than they seem. Served as a side to grilled fish or meat, or as a light vegetarian main with crusty bread, this dish shows the Portuguese approach to vegetables: let good olive oil and proper roasting do most of the work.

Pro Tips
- →
Give the vegetables space on the pan -- crowding causes steaming instead of proper caramelized roasting.
- →
Roast the garlic cloves whole with their skin on to keep them from burning, then squeeze out the softened cloves at the end.
- →
Toss the herb butter through the vegetables while they're still hot so it melts evenly.
Variations
- •
Add cubed chorizo for a heartier, more substantial version.
- •
Use sweet potatoes alongside or instead of regular potatoes for extra sweetness.
- •
Finish with a squeeze of lemon juice for brightness alongside the herb butter.
Storage
Refrigerate up to 3 days. Reheat in a 200°C (400°F) oven for 10 minutes to re-crisp rather than microwaving.
