Brown butter and sage Prawn Gratin

Prep everything first: chop the aromatics, measure the brown butter and sage elements, and pat the prawn dry so it colours well.

Warm the olive oil in a large pan over a medium heat and soften the onion and garlic until sweet and translucent, about 5 minutes.

Turn up the heat and add the prawn. Transfer to the oven and bake until set, bubbling and golden on top.

Stir in the dried oregano and the rest of the brown butter and sage flavours, letting them cook out for a minute until fragrant.

Add the green beans along with a splash of stock or water, then cover and cook gently until everything is tender and the sauce clings.
