Method

  1. Sprinkle the courgettes with a pinch of sea salt flakes and lay them on a plate with another plate on top. Put a weight or tin on top to help push out the liquid.

  2. Heat 1 tbsp olive oil in a non-stick frying pan and add the tomatoes and garlic. Cook over a medium heat, stirring, for 5 mins until thickened. Tear in the basil, if using, and season. 

  3. Heat the oven to 200C/180C fan/gas 6 and oil a roasting dish. Combine the flours in a bowl. Pour away the water from the courgette. Dip the courgette slices into the egg, then into the flour, and arrange in a layer over the bottom of the dish. Top with a few slices of mozzarella, followed by a layer of the tomato sauce, and repeat with another layer of courgette, mozzarella and sauce. Toss the cheese and breadcrumbs together, then scatter over the top.

  4. Drizzle with a little more olive oil, and bake for 40-45 mins until golden and bubbling. Serve with a herby red onion salad and some bread to mop it up, if you like. Can be frozen for up to two months.

I was very pleasantly surprised by how this recipe turned out. I am not a massive fan of courgette but had a glut from the garden and was looking for what to do with them. I expected this gratin to turn out underwhelming and bland, but actually it was delicious! I divided it into 4 separate dishes before cooking so I could freeze each portion separately and for this I think it needs more than one can of chopped tomatoes. I padded it out with cherry tomatoes from the garden, but you could just add an extra can. I also used 3 courgettes to use them up and found that it wasn't excessively courgette-y, you could probably get away with feeding picky eaters in your family with this recipe! It's not really big enough for 4 adults on it's own, you'd need something else on the side (big salad?) to pad it out.

Tasty way to use up my glut of courgettes. Serves 2 as a main dish or 4 as a vegetable side dish. Not sure what the egg & flour do , possibly helped tomatoes to thicken in dish.

Why are the courgettes coated in egg and flour before baking? I was expecting them to be fried at this point, but they're just layered in. I see one of the comments mentions this.
