Instructions

Prepare the Topping

Boil or steam the cauliflower until very tender, then drain well.
Mash the cauliflower and add the Cheddar cheese, sour cream, butter, salt and pepper. Blend well until combined.

Prepare the Filling

In a large pan or skillet, heat the olive oil and add the leeks, cooking until softened.
Add the garlic and celery and cook for 2 minutes.
Add the chopped mushrooms and cook until they release their moisture and start to brown.
Add the stock, salt, pepper and dry porcini mushrooms and cook for 5 minutes.
Add the tarragon and cook for a further 2 minutes.
Remove from the heat and stir in the sour cream for a creamy mixture.

Assembly

Preheat the oven to 375°F (190°C).
Spread the mushroom leek filling in an 9 x 13 inch ovenproof dish.
Carefully spread the cauliflower mash over the top of the filling, creating an even layer.
If desired, sprinkle some grated cheese on top for a golden crust.
Place the dish in the preheated oven and bake for 20-25 minutes or until the top is slightly golden and the filling is bubbling at the edges.
Once done, allow it to cool for a few minutes before serving.
