Start by cleaning your leek: cut it lengthwise, give it a quarter turn, and slice it again, leaving the root intact. Rinse under running water to get rid of any dirt.
In a large pan, heat up 2 tablespoons of olive oil over medium heat.
Add your sliced leek and chopped onion. Sauté for about 5 minutes until they're soft but not browned.
Stir in the minced garlic and let it cook for another 2 minutes.
Now, add the Arborio rice and cook it until the rice just starts to look translucent.
Pour in 1/2 cup of dry white wine and stir constantly until the wine is soaked up.
Start adding your warm broth, 2-3 ladles at a time, stirring all the while until the liquid is absorbed. Keep adding broth this way until the rice is al dente, which will take about 18-20 minutes. You’ll know it’s ready for the next ladle when you can make a trench in the rice and it holds its shape for a few seconds.
When you add the last bit of broth, stir in that caramelized apple and fennel mix. Cook until the stock is absorbed and the risotto is creamy and loose, like a cozy bowl of oatmeal.
Stir in 2 tablespoons of butter until it’s melted and creamy.
Add the crumbled goat cheese and stir until it’s all smooth and delicious.
Season with salt and pepper to taste.
