Step 1

Whisk 4 tbsp olive oil with the lemon juice, zest and bruised garlic cloves.

Step 2

Season with salt and pour into the bottom of a large baking dish.

Step 3

Toss the courgettes with a little more oil. Heat a griddle to high. Add the courgettes cut-side down and griddle for 4-5 minutes until really chargrilled.

Step 4

Turn over and griddle for another couple of minutes, then lay them cut-side down in the marinade.

Step 5

Repeat until you’ve griddled all the courgettes. Leave to marinate at room temperature for 1 hour.

Step 6

To serve, put the courgettes on a platter, spoon over some of the marinade and sprinkle with mint.
