Begin by patting the chicken thighs dry with paper towels. Season both sides with salt, black pepper, and paprika.
Heat the olive oil in a large skillet over medium-high heat. Add the chicken thighs skin-side down and sear for 5-7 minutes until crispy. Flip and cook for another 5 minutes. Remove from skillet.
In the same skillet, add the finely chopped onion and sauté for about 2 minutes until translucent. Add minced garlic and sauté for another minute.
Incorporate the sliced mushrooms and cook for 4-5 minutes until tender and browned.
Pour in the chicken broth, scraping any browned bits from the skillet. Let it simmer for a few minutes.
Lower the heat and stir in the heavy cream and dried thyme until well combined.
Return the seared chicken thighs to the skillet skin-side up, spoon some sauce over them, cover, and simmer on low heat for about 25 minutes until cooked through.
Taste the sauce and adjust seasoning with salt and pepper if desired.
Plate the chicken thighs drizzled with the creamy mushroom sauce and garnish with parsley before serving.
