Description

A slow cooker version of classic butter chicken with tender chicken thighs in a creamy, spiced tomato sauce.


Ingredients

  • 1 tablespoon melted coconut oil or olive oil
  • 1 large yellow onion, finely diced (about 1½ cups)
  • 1 tablespoon ginger paste
  • 1 tablespoon minced garlic
  • 1¼ teaspoons smoked paprika
  • 1¼ teaspoons ground cumin
  • 1¼ teaspoons ground turmeric
  • 1¼ teaspoons salt
  • 2¼ teaspoons garam masala
  • ⅛ teaspoon red pepper flakes (optional)
  • 1 teaspoon sugar (optional)
  • 1 (14.5‑ounce) can diced tomatoes (or crushed, fire‑roasted works well)
  • 2 pounds boneless skinless chicken thighs
  • 8 tablespoons unsalted butter (sliced into tablespoons)
  • ½ cup heavy cream
  • ⅓ cup finely chopped cilantro (optional)
  • Naan (for serving)
  • Cooked rice (for serving)

Instructions

  1. Heat a large nonstick pan over medium‑high heat. Add the oil, and once hot, sauté onion, garlic, and ginger, stirring occasionally, until golden (3–6 minutes).
  2. Add smoked paprika, cumin, turmeric, salt, garam masala, red pepper flakes (if using), and sugar (if using). Stir constantly for 1–3 minutes until fragrant.
  3. Stir in the diced tomatoes, scraping the bottom of the pan. Let the mixture cool slightly, then transfer it to the slow cooker.
  4. Trim excess fat from the chicken thighs (leaving a little fat for flavor). Add the thighs to the slow cooker and stir to coat them in the sauce. Arrange the thighs in a single layer, smooth side down.
  5. Cover and cook on high for 2½–4 hours (or on low for 4–6 hours), until the chicken reaches 165 °F (74 °C).
  6. Remove the chicken and chop into bite‑sized pieces. Use an immersion blender (or transfer to a regular blender) to purée the sauce until smooth. (Blend carefully — see Notes.)
  7. Return the blended sauce to the slow cooker. Stir in the butter and heavy cream until smooth and fully combined.
  8. Add the chopped chicken back into the sauce. Stir in cilantro (if using). Adjust seasoning as needed.
  9. Serve hot over rice with warmed naan on the side.

Notes

  • You can use pre‑prepared ginger and garlic paste from the refrigerated section to save time.
  • Don’t skip the garam masala — it’s essential for authentic butter chicken flavor.
  • Chicken thighs are preferred because they stay juicy in the slow cooker. Chicken breasts may dry out.
  • Warm naan by spraying with oil and lightly grilling, or heating in a skillet, toaster, or microwave (under a damp towel).
  • Let the sauce cool slightly before blending to avoid spills or burns. If using a blender not designed for hot liquids, secure the lid with a towel to contain steam.
  • Leftovers can be stored in a sealed container in the fridge for 3–5 days. Reheat gently and add a splash of cream or water if the sauce has thickened too much.
