This grilled cheese is insane. It’s PACKED with flavour. I love pairing savoury and sweet flavours together and this sandwich does just that. The sweet syrupy caramelized onions and mushrooms sandwiched between fig jam and goat cheese is ridiculously good. Although the goat cheese won’t give you that ooey-gooey grilled cheese texture, the flavours of this sandwich will blow you away that you won’t even miss it!
Grilled cheese (or toasties in Australia), are THE ultimate comfort food. It’s quick, easy, and indulgent.

This post is a continuation of the grilled cheese lunch marathon we had last week. You can read more about it in the sriracha butter apple grilled cheese post.
We made:
- Sriracha butter apple grilled cheese
- Bacon Brie and Apricot grilled cheese
- Goat cheese caramelized onions and fig grilled cheese (this recipe)
- Spinach Balsamic Blueberry grilled cheese
Don’t worry, I’ll be posting the recipe to all 4 grilled cheeses above – just give me a little time 🙂

Unlike my other recipes, I didn’t make a video for these sandwiches since the instructions are fairly straightforward (let me know in the comments if you’d like me to make a video). I was also a little too excited when making these sandwiches and forgot to take some photos of the process 😅. I’ll update this post with more photos the next time I make them again (which probably won’t be long).
Anyways, without further ado, here’s the recipe!
This recipe takes a little more effort than the other grilled cheeses posted so far because caramelizing onions and mushrooms can be a little time-consuming – but definitely worth it for those flavours!
Ingredients you’ll need:
- 50g unsalted butter
- 1 small onion (~1.5 – 2 cups), sliced
- 2 cups mushrooms, sliced
- Mayonnaise for spreading – this is the secret to a crisp golden grilled cheese! Mayo gives a nicer crisp and colour compared to butter.
- 4 slices of white bread (I like to use sourdough, but whatever white bread you’ve got works)
- 4 Tbsps fig jam (2 Tbsps per sandwich) – you can replace it with most jams that aren’t too overly sweet. I’ve tried it with apricot jam before and it worked really well.
- Goat cheese, enough to spread on two slices of bread – you can either keep it as a slice or if your goat cheese is soft and crumbly, then use it as a spread. My favourite is Meredith Dairy goat cheese in olive oil.

Directions:
In a skillet on medium heat, melt the butter. Once the butter is melted, add in the onions and mushrooms. Cook until the onions become brown and syrupy (~5-8 mins). Set aside.
Spread mayonnaise on one side of each slice of bread (this will be the outside of the sandwich that you will toast to get that crisp golden colour).


Assemble your grilled cheese: spread mayonnaise on two slices of bread. On the other side of these two slices of bread, spread one with fig jam and the other with goat cheese. Sandwich caramelized onions and mushrooms between the fig and goat cheese bread slices (with the mayo on the outside).
(Incase that sentence was confusing, your layers should be: mayonnaise + bread + fig jam + caramelized onions and mushrooms + goat cheese + bread + mayonnaise).

Get a pan on the stove on medium heat and once your pan is heated, place your sandwich in the pan (you don’t need any oil in the pan because the mayonnaise on the outside of your sandwich will act as your oil base).

Toast your sandwich until the bread is a beautiful crisp golden brown (~3-5mins), then carefully flip your sandwich over and toast the other side. (Tip: if your sandwich is quite tall, you can gently flatten your sandwich as your cheese melts. This will help compact your sandwich and make it less messy to eat.) Once your second side is toasted, repeat with your second sandwich and serve immediately! Enjoy!!
