In a large cast iron enamel-coated pot (I use a 5 quart pot), heat the olive oil over a medium heat.

Generously season the chicken thighs with salt and pepper on both sides.

Brown the chicken thighs in the pot in batches; it will likely be 3 batches.

Slice the leek into thin half moons.

When the chicken thighs are browned and removed from the pot, turn down the heat and add the leeks, minced garlic and mushrooms into the pot.

Cook until the leek has softened and the mushrooms have started to cook down a little, about 5 minutes.
