01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside.
02 - In a shallow bowl, whisk the eggs until fully beaten. In a separate wide bowl or dish, combine the panko breadcrumbs, Parmesan cheese, chopped parsley, thyme, rosemary, garlic powder, salt, and black pepper. Mix thoroughly to distribute the herbs evenly.
03 - Pat the chicken thighs dry with paper towels to ensure proper adhesion. Dip each thigh into the beaten eggs, allowing excess to drip off, then press firmly into the herb-breadcrumb mixture, coating all sides evenly. Place coated thighs on a clean surface or tray.
04 - Heat the olive oil in a large skillet over medium-high heat until shimmering. Place the chicken thighs skin-side down and sear for 3 to 4 minutes until the crust turns a deep golden brown. Transfer the seared thighs to the prepared baking sheet, skin-side up.
05 - Bake the chicken in the preheated oven for 25 to 30 minutes, until the internal temperature reaches 165°F when measured at the thickest part with an instant-read thermometer. The crust should be deeply golden and crispy.
06 - While the chicken bakes, combine the rice, water or chicken broth, butter, and salt in a medium saucepan. Bring to a rolling boil over medium-high heat, then reduce the heat to low, cover tightly, and simmer for 15 minutes. Remove from heat and let stand, covered, for 5 minutes. Fluff gently with a fork before serving.
07 - In the same skillet used for searing the chicken, melt the butter over medium heat. Add the minced garlic and sauté for 1 minute until fragrant, being careful not to let it brown. Pour in the heavy cream and chicken broth, stirring to combine. Bring to a gentle simmer and cook for 3 to 4 minutes. Whisk in the Parmesan cheese until melted and smooth, then stir in the chopped parsley. Season with salt and pepper to taste. Continue simmering until the sauce coats the back of a spoon.
08 - Spoon a generous portion of fluffy rice onto each plate. Arrange the golden herb-crusted chicken thighs on top and drizzle generously with the creamy garlic sauce. Serve immediately while hot.
