Tips for making the best grilled cheese sandwich:

Use thick slices of good quality bread. Of course regular white bread will work but if you want a fantastic grilled cheese sandwich, using sourdough or another type of good bread will make all the difference.

Cheese! Using a combination of cheeses will result in the ooey-gooey melted cheese quality you’re after WITH added flavor. Only using mozzarella will result in not much of that stretchy cheese-goodness. Likewise, only using a sharp cheese like cheddar means you lose out on that creaminess. Using a combination of a good melting cheese like mozzarella, fontina or taleggio and something stronger like aged cheddar, Gruyere, Parmesan, etc. will give you the most delicious end result.

Extras: Adding slices of smoked ham, crispy bacon or in this case, garlic butter mushrooms means that you take your sandwich from good to great. Even adding herbs like basil will transform a simple grilled cheese.

How to make garlic butter mushrooms

Slice mushrooms of your choice into thin slices. I like using portabellini/Chestnut/Cremini mushrooms. Heat a large frying pan over medium-high heat and add two tablespoons of butter. Add the mushrooms and cook until they are well browned. The mushrooms might release a lot of liquid. Simply allow the liquid to evaporate and allow them to brown on all sides. Once the mushrooms have browned, add the garlic, chilli flakes if using and oregano. Cook until the garlic is fragrant then season with salt and pepper and a squeeze of lemon juice then use.
