Ingredients

For the Cajun Butter Chicken

  • 4 boneless, skinless chicken breasts
  • 1/2 cup unsalted butter, melted
  • 2 tablespoons Cajun seasoning
  • 1 medium onion, thinly sliced
  • 1 teaspoon garlic powder
  • 1/2 teaspoon paprika
  • 1/2 cup chicken broth
  • 1/2 cup heavy cream
  • Salt and black pepper, to taste
  • Fresh parsley, chopped, for garnish

For Serving

  • Cooked white rice

Instructions

  1. Prepare the chicken. Pat the chicken breasts dry with paper towels. Season both sides with the Cajun seasoning, garlic powder, paprika, and a little black pepper. Taste your Cajun seasoning first, as some blends already contain salt.
  2. Layer the slow cooker. Spread the sliced onion across the bottom of the crockpot. Arrange the seasoned chicken breasts on top.
  3. Make the butter mixture. In a small bowl, whisk together the melted butter and chicken broth. Pour the mixture evenly over the chicken and onions.
  4. Slow cook. Cover and cook on LOW for 3–4 hours or HIGH for 2–3 hours, depending on the thickness of the chicken and your slow cooker. Check the thickest part of each breast with a food thermometer; chicken must reach 165°F (74°C).
  5. Add the cream. Once the chicken is cooked through, stir the heavy cream into the cooking liquid. Cover and cook on LOW for another 10–15 minutes, until the sauce is hot and creamy. Avoid boiling the sauce vigorously.
  6. Adjust the sauce. Taste and add salt or black pepper if needed. If the sauce is too thin, remove the chicken temporarily and simmer the sauce in a saucepan until it reaches your preferred consistency.
  7. Garnish and serve. Spoon the creamy Cajun butter sauce and onions over the chicken. Sprinkle with fresh chopped parsley and serve with cooked white rice.

Notes

  • Control the spice: Cajun seasoning varies in heat and saltiness. Use less for a milder dish or choose a low-sodium blend.
  • Avoid overcooking: Chicken breasts can dry out in a slow cooker. Begin checking for doneness at the earlier end of the suggested cooking time.
  • Add cream near the end: Adding heavy cream after the chicken cooks helps prevent the sauce from separating during prolonged cooking.
  • Thicker sauce: For a thicker sauce, transfer the cooking liquid to a saucepan and simmer gently until reduced. Do not add flour or cornstarch unless you prefer a thicker gravy.
  • Serving ideas: Serve with white rice, mashed potatoes, or steamed vegetables to soak up the Cajun butter sauce.
  • Storage: Refrigerate leftovers in an airtight container for up to 3–4 days. Reheat gently until steaming hot, adding a splash of broth if the sauce becomes too thick.
