It’s grilled cheese-ish with two surprising ingredients.

Cheese toasties have been a British staple for centuries.

However, Austens cheese toastie includes two surprising ingredients: egg and mustard.

Once out of my toaster, Austens cheese toasties were exquisite.

A melty, cheesy custard topping slightly jiggled atop two slices of buttery toast.

Thanks to the mustard, the cheese tasted extra savory and beautifully aged.

With each bite, melty, creamy, flavorful cheese mingled with traces of runny yolk.

This intense creaminess was paired with crispy, crunchy, buttery toast.

(Maybe I should channel my inner Austen and go back to writing rom-coms instead of about food!)

My husband raved about the cheese toastie and wanted seconds, as did I.

So I made another batch and turned the cheese toasties into grilled cheese sandwiches.

Crack a large egg into a medium bowl.

Season with a little salt and pepper and stir until combined.

Then, spoon the mixture evenly over the two slices of bread.

Alternatively, pan-fry or grill the toast in a buttered skillet or frying pan.

Just be sure to cover the skillet or pan with a lid to help the cheese melt.

I made two versions of Austens favorite cheese toastie.

The other I kept open-faced.

If youre into spicy food, you’re able to top the cheese toastie with choppedkimchi.

The kimchi will give the toastie a nice kick and added crunch.

Alternatively, drizzle hot honey over the cheese toastie for some heat and a balancing sweetness.
