Season chicken on both sides with salt and pepper to taste. Heat 1 tablespoon butter and olive oil in a medium oven-safe skillet over medium-high heat until melted and hot. Place chicken thighs skin-side down and sear 2-3 minutes on both sides until golden brown. Remove from skillet and set aside.
Drain drippings from pan and wipe clean. Heat remaining 1 tablespoon butter over medium-high heat. Add garlic to pan and saute 1 minute until garlic is fragrant. Add honey, lemon juice, and zest to pan and bring to a simmer, then reduce heat to medium-low and let simmer 5 minutes until slightly thickened. Stir in dill and salt and pepper to taste.
Nestle chicken thighs back into pan and use a spoon to drizzle some of the sauce over top. Arrange lemon slices and dill around chicken. Bake chicken at 400F 25-30 minutes or until chicken registers 165F
Creamy Mascarpone Rice
While the chicken bakes, prepare the rice. In a large saucepan over medium-high heat, melt butter and saute garlic in butter 30 seconds until fragrant. Stir rice into pan and let cook 1 minute until lightly toasted, being careful not to let the garlic burn.
Add chicken broth to skillet and cover. Bring rice to a simmer over medium-high heat, then reduce heat to medium-low, cover and let simmer 20-25 minutes until rice is tender and creamy, stirring occasionally.
Stir mascarpone cheese and Parmesan into rice until melted and creamy. Season with salt and pepper to taste.
Nestle lemon chicken thighs on top of creamy rice and serve immediately while warm. Enjoy!
