Pat the chicken thighs dry with paper towels, then season generously with salt and pepper on both sides.
Heat a large skillet over medium-high heat and add a tablespoon of butter. Once melted and sizzling, place the chicken thighs skin-side down. Cook for about 8-10 minutes until the skin is golden brown and crispy, then flip and cook the other side for another 8 minutes until cooked through. Remove the chicken and set aside.
Add the remaining butter to the same pan. Once melted, add the minced garlic and sauté for about 30 seconds until fragrant and slightly golden, stirring constantly to prevent burning.
Meanwhile, rinse the rice under cold water until the water runs clear. Add the rice to the skillet with garlic and butter, stirring to coat each grain in the fragrant mixture. Toast the rice for about 2 minutes until it turns lightly golden and smells nutty.
Pour in the chicken broth or water, scraping the bottom of the pan to loosen any browned bits. Bring the mixture to a boil, then reduce the heat to low, cover, and simmer for 15 minutes until the rice is tender and the liquid is absorbed.
Once the rice is cooked, stir in grated Parmesan cheese and adjust seasoning with salt and pepper to taste. Keep warm.
Return the cooked chicken to the skillet, placing it on top of the rice. Cover loosely and let rest for 2-3 minutes so the flavors meld and the chicken stays juicy.
Serve the crispy chicken thighs alongside the creamy Parmesan rice, spooning any garlic butter drizzled over the top for added flavor. Enjoy hot with your favorite vegetables or sides.
