Cheesy Leek Gratin
This is one of Andrea aka Meat Smoke Fire Cameragirl’s favourite vegetable side dish: Cheesy Leeks. This recipe combines the creamy richness of cheese sauce with the mild sweet leek flavour. Â In this particular version we’ve added a breadcrumb topping to transform it into a gratin; it’s equally as good without the crunchy topping.
This is a great pairing with your favourite roast or dinner, our particular favourite is with a rotisserie gammon, which can be cooked alongside your main course on the Big Green Egg. Â Cheesy Leek Gratin is a guaranteed crowd-pleaser in the Meat Smoke Fire house.

Ingredients
- 3 medium leeks, trimmed
- 50g butter
- 50g plain flour
- 500ml milk
- 150g cheddar cheese, grated
- 2 tbsp dijon mustard
- 2 handfuls breadcrumbs, optional
- salt and pepper to taste
- oil, for cooking
Method
- Setup your Big Green Egg for an indirect cook with the stainless steel grid on top of your ConvEGGtor.  Set your Egg to 200°C.
- Cut your leeks into 2cm rounds and pop into the bottom of an ovenproof baking dish. Â We don’t cook our leeks but if you wanted to shorten the cooking time you could steam for 6 to 8 minutes until the leeks are tender.
- To make the sauce, you start with a classic roux, so melt the butter in a pan and then stir in the flour. Â Keep stirring, you’re looking to make a thick paste. Â Once you’ve got a paste, give it a couple of minutes to cook the flour; you’ll start to see bubbles forming in the paste.
- Add the milk gradually, a bit at a time, stirring continously, until all the milk has been added. Â As the milk heats up, it will start to thicken, so keep stirring to avoid any lumps forming.
- You’re looking for the sauce to coat the back of a spoon, at this point you can stir in the dijon mustard.
- Remove from the heat and add the cheese. Â The cheese will melt in the residual heat of the sauce. Â If you plan to add breadcrumbs, then keep back a little cheese to mix through the breadcrumbs.
- Taste the sauce; we season with a little salt and lots of ground black pepper. Â We might even add a bit more mustard and or cheese depending how the sauce tastes.
- Now you can pour the cheese sauce into the dish to cover the leeks. Â If you’re making the gratin, you can add the breadcrumb topping at this stage.
- Place the dish on the grid and cook for about 40 minutes until the top is crisp and bubbling and the leeks have softened.
- Once cooked, remove from the heat and serve with your favourite roast or preferred dinner.
