Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper or aluminum foil for easy cleanup.

Pat the chicken thighs completely dry with paper towels. Rub them thoroughly with olive oil, kosher salt, black pepper, and smoked paprika, then place them skin-side up on the prepared baking sheet.

Roast the chicken in the preheated oven for 40 to 45 minutes, or until the skin is crispy, deeply golden brown, and the internal temperature reaches 165°F (74°C).

While the chicken roasts, prepare the walnut sauce. In a food processor or blender, combine the shelled walnuts, garlic cloves, chicken broth, heavy cream, white wine vinegar, and ground coriander.

Blend the mixture on high speed for 1 to 2 minutes until it becomes completely smooth and creamy. If the sauce appears too thick, add an extra splash of chicken broth to reach your desired consistency.

Transfer the blended walnut sauce to a small saucepan and warm it over low heat for 3 to 5 minutes, stirring occasionally, just until heated through. Do not let it boil.

Serve the crispy roasted chicken warm, generously drizzled with the creamy walnut sauce and garnished with fresh chopped parsley. This dish pairs beautifully with steamed green beans or fluffy white rice.
