Jamie Oliver Courgette Gratin is a baked dish made by layering sliced courgettes with cream or a light béchamel sauce and cheese. It is then baked until tender inside and golden on top, creating a comforting, oven-finished vegetable dish.
Preheat your oven to 190°C (170°C fan). Lightly grease a baking dish.
Heat olive oil in a pan over medium heat. Add chopped onion and cook for 3–4 minutes until soft. Stir in garlic and cook for another minute.
Add sliced courgettes to the pan and cook for 5–6 minutes until slightly softened. Season with salt and pepper.
Pour in the cream and allow it to simmer gently for 2–3 minutes so flavors combine.
Spoon the mixture into the prepared dish. Sprinkle grated cheddar or Gruyère evenly on top, followed by Parmesan.
Bake for 25–30 minutes until golden and bubbling. The top should be lightly crisp.
Let the gratin rest for 5 minutes before serving. This helps it set slightly.
