Ingredients
  

  • 1.5 pounds boneless, skinless chicken thighs (or breasts, but thighs stay juicier)
  • 2 tablespoons olive oil
  • 1 tablespoon butter (for richness; optional but recommended)
  • 4 cloves garlic, minced
  • 1 small onion, finely chopped (optional; adds sweetness without many carbs)
  • 1 (14.5-ounce) can diced tomatoes (no sugar added)
  • 2 tablespoons tomato paste (boosts depth and body)
  • 1/2 cup chicken broth (low sodium)
  • 1 teaspoon dried oregano
  • 1 teaspoon dried basil
  • 1/2 teaspoon smoked paprika (optional, for a gentle smoky note)
  • 1/4 teaspoon red pepper flakes (optional heat)
  • Salt and black pepper to taste
  • 2 tablespoons chopped fresh parsley or basil for finishing
  • 1–2 tablespoons capers or sliced olives (optional, for briny punch)
  • Grated Parmesan for serving (optional, but great)

Method
 

  1. Prep the chicken: Pat the chicken dry and season generously with salt, black pepper, and half the oregano and basil.
  2. Sear the chicken: Heat olive oil in a large skillet over medium-high. Add the chicken and sear 4–5 minutes per side until golden. Remove to a plate. It doesn’t need to be fully cooked yet.
  3. Sauté aromatics: Lower heat to medium. Add butter, onion, and a pinch of salt. Cook 3–4 minutes until translucent. Stir in garlic and cook 30–60 seconds until fragrant.
  4. Build the sauce: Add tomato paste and cook 1 minute, stirring to caramelize slightly. Pour in diced tomatoes and chicken broth. Stir in remaining oregano, basil, smoked paprika, and red pepper flakes. Simmer 3 minutes.
  5. Nestle and simmer: Return chicken and any juices to the skillet. Submerge in sauce. Simmer gently 8–10 minutes, flipping once, until chicken is cooked through and tender.
  6. Finish and taste: Stir in capers or olives if using. Taste and adjust salt, pepper, and heat. Sauce should be savory and bright; add a splash more broth if too thick.
  7. Garnish and serve: Sprinkle with fresh parsley or basil. Add grated Parmesan if you like. Serve hot with your favorite keto sides.
