The first time I ever ate a sourdough toastie was a pivotal moment and a game changer in the cheese toastie world. It now has to be sourdough. Every time.
This is a naughty lunch because I use not one but three cheeses, and lots of butter. If you don't have all three cheeses or have other cheeses you think go well together then go for it. I chose the parmesan for its punch of flavour, the buffalo mozarella for its stringy, juiciness and the cheddar for its melty loveliness and goes so well in a toastie.
I always think of leeks as giant spring onions. Are you with me on this? No? OK. Well Cheese and onion are great pals and mushrooms, love them or hate them, go really well together and gives a lovely meaty texture. And Thyme finishes off this veggie mixture beautifully.
Although tempting, it can't be eaten everyday. It's so rich and luxurious it would ruin it to over do it. But it is a great combo.
1 tsp olive oil
1 leek, finely sliced
100g mushrooms, sliced
2 slices of your best sourdough loaf
15g of parmesan, finely grated
15g cheddar, coarsely grated
1/3 of a ball of mozzarella, roughly torn
Salt and pepper
Fry the leeks and mushrooms with the olive oil with a pinch of salt and pepper for around 10 minutes on a medium heat until the leeks are soft, not tough. After 5 minutes, add the thyme.
Get one of the slices of bread and sprinkle the parmesan evenly on first, then the mozzarella, then the leek and mushroom mixture and then the cheddar. Put the other slice of bread on top and butter generously. Get a non stick frying pan and sit this on top of your toastie so that the butter sticks to the inside of the pan. Flip the pan over and butter the other slice of bread. Turn on the heat and gently fry on a medium heat for 2 minutes on each side, or until the cheese has melted. Be careful not to burn the bread. When done serve straight away on its own or with a green side salad.
If you want to go dairy free for whatever reason there are some awesome vegan cheeses out there. If that doesn't do it for you crush up some pine nuts, cut the mushrooms chunkier. Alternatively use some tofu. I like the smoked kind but there are other flavours. It will give the toastie that lunch of flavour you're wanting from a toastie.
If you fancy some meat in your toastie then bacon or ham goes so well for that contrast in flavour and texture. I would use tuna if you want to go fishy for a classic tuna melt.
