R.l.P Legendary Actress.

Heat olive oil and 1 tbsp butter in a Dutch oven or heavy pot.
Sear chicken on both sides until deep golden—color means depth, like backstory.
Remove and set aside.

Build the Supporting Cast
Into the same pot, add onion, garlic, carrots, and celery.
Sauté until softened, letting the browned bits on the bottom loosen—these fragments are flavor memories.

A Splash of Drama
Pour in the white wine. Let it simmer and reduce by half.
This step is tension: what was sharp becomes soft, what was loud becomes balanced.

The Slow Storytelling
Return chicken to the pot. Add stock, bay leaf, rosemary, thyme, lemon zest.
Bring to a gentle simmer.
