Ingredients
Method
The Slow Caramelization
- Preheat the oven to 400°F. Generously coat a 9x9-inch ceramic baking dish with vegetable oil spray or butter.
- Heat the olive oil and unsalted butter in a large skillet over medium-low heat until melted and foaming.
- Add the thinly sliced yellow onion and cook slowly, stirring occasionally, until deeply soft and completely translucent, about 15 to 20 minutes.
- When the onions begin to turn golden and deeply caramelize, aggressively stir in the chopped fresh chives and the balsamic vinegar. Season with the kosher salt and coarse black pepper.
- Cook until the balsamic reduces and the onions transform into a dark, sticky, syrupy tangle, about 5 minutes more. Remove the pan from the heat.
The Custard Emulsion & Absorption
- In a large, heavy glass or ceramic mixing bowl, vigorously whisk the half-and-half and the beaten eggs until completely unified and pale yellow.
- Drop the 1-inch bread cubes directly into the wet custard. Use a wooden spoon to firmly push the bread down, ensuring every cube is entirely submerged in the liquid.
- Let the bread rest undisturbed to fully absorb the custard, about 15 to 20 minutes. (This critical resting phase allows the starches to swell, preventing a dry or rubbery bake).
The Architectural Integration & Bake
- Once the majority of the liquid has been absorbed into the bread, gently fold the syrupy, caramelized onions into the bowl, taking care not to shred the softened bread cubes.
- Transfer the heavily saturated bread pudding mixture evenly into the prepared 9x9-inch baking dish.
- Scatter the crumbled goat cheese generously and evenly across the absolute top of the pudding.
- Bake in the preheated 400°F oven for 30 to 40 minutes, until the custard is fully set in the center, the goat cheese is melted, and the exposed bread edges are deeply golden brown and shattered.
- Allow the dish to rest for 10 minutes to stabilize the custard before slicing. Garnish with additional fresh chives and serve hot.
