01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper and set aside.
02 - In a shallow dish, whisk the eggs until well blended. In a separate wide bowl, 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. Dip each thigh into the beaten eggs, allowing excess to drip off, then press firmly into the herb breadcrumb mixture, ensuring an even, adherent coating on all sides.
04 - Heat the olive oil in a large skillet over medium-high heat. Place the chicken thighs skin-side down and sear for 3 to 4 minutes until a deep golden crust forms. 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, or until the internal temperature reaches 165°F when measured at the thickest part. Remove from the oven and let rest briefly before serving.
06 - While the chicken bakes, combine the rice, water or chicken broth, butter, and salt in a 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. Pour in the heavy cream and chicken broth, stirring to combine, and bring to a gentle simmer for 3 to 4 minutes. Whisk in the Parmesan cheese and parsley, then season with salt and pepper. Continue simmering until the sauce thickens slightly and 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 liberally with the creamy garlic sauce. Serve immediately.
