Chicken thighs in a creamy garlic pan sauce — rich, keto-friendly, and made in one skillet. This low carb dinner is what comfort food looks like without the carbs.
Pat chicken thighs dry and season both sides evenly with kosher salt, black pepper, and dried thyme.
Heat olive oil and butter in a large skillet over medium-high heat. When butter is foaming, add chicken thighs skin side down. Sear 5–7 minutes until skin is deeply golden; flip and cook another 4 minutes. Remove chicken to a plate but keep skillet and drippings.
Lower to medium heat. Add minced garlic and sauté in the pan drippings about 1 minute, until fragrant but not browned.
Pour in chicken broth, scraping the bottom with a wooden spoon to deglaze. Simmer 2–3 minutes to reduce slightly, then stir in heavy cream and grated Parmesan cheese. Bring to a gentle simmer (do not boil), stirring to melt cheese for a smooth sauce.
Return the chicken thighs (skin side up) and juices to the skillet; spoon some sauce over. Simmer uncovered on low heat for 12–15 minutes, until chicken is cooked through (internal temp 175°F/80°C) and sauce thickens.
Add fresh spinach and stir gently into the sauce until just wilted, 1–2 minutes. Serve chicken thighs topped with plenty of creamy garlic sauce.
