Instructions

1. Elevate the oven temperature to 180°C (350°F), creating an ideal environment for the gratin’s golden transformation.
2. Infuse the chicken with a robust blend of salt, pepper, Provençal herbs, and paprika. Sear in a skillet over medium heat until achieving a rich, caramelized exterior. Allow to cool briefly, then slice into delectable bite-sized morsels.
3. In the same skillet, gently sweat onions and garlic until translucent and fragrant. Introduce mushrooms, cooking until they release their moisture and become tender and golden-edged.
4. Craft a luscious binding sauce by whisking eggs, sour cream, and milk together. Enhance with a carefully selected medley of herbs and spices. Fold in most of the cheese, along with the prepared chicken and mushroom mixture.
5. Transfer the luxurious combination into a generously greased baking dish, creating an even layer. Sprinkle the remaining cheese across the top for a tantalizing golden crust.
6. Slide the gratin into the preheated oven, baking for 25-30 minutes until the surface turns a beautiful golden brown and the center sets completely.
7. Finish by scattering freshly chopped green onions over the top, adding a final burst of color and freshness. Serve immediately while still piping hot, allowing the flavors to fully bloom.
