Ingredients
  

  • 2 pounds boneless, skinless chicken breasts (or thighs for extra tenderness)
  • 2 tablespoons Cajun seasoning (store-bought or homemade), divided
  • 1 teaspoon smoked paprika (optional for deeper flavor)
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/2 teaspoon salt (adjust to taste)
  • 1/4 teaspoon black pepper
  • 1 red bell pepper, thinly sliced
  • 1 green bell pepper, thinly sliced
  • 1 small yellow onion, thinly sliced
  • 3 cloves garlic, minced
  • 1 cup chicken broth (low-sodium)
  • 4 ounces cream cheese, cubed and softened
  • 1/2 cup heavy cream
  • 1/4 cup grated Parmesan cheese
  • 2 tablespoons butter
  • 1 tablespoon olive oil
  • Juice of 1/2 lemon (about 1 tablespoon)
  • Fresh parsley or green onions, chopped, for garnish
  • Optional: 1/4 teaspoon cayenne pepper for extra heat

Method
 

  1. Season the chicken: Pat the chicken dry. In a small bowl, mix 1 tablespoon Cajun seasoning, smoked paprika, garlic powder, onion powder, salt, and black pepper. Rub this mixture evenly over the chicken.
  2. Layer the aromatics: Add the bell peppers, onion, and minced garlic to the bottom of the slow cooker.
  3. Sear for extra flavor (optional but recommended): Heat olive oil and butter in a skillet over medium-high heat. Sear the chicken 2–3 minutes per side until lightly browned. Transfer to the slow cooker on top of the vegetables.
  4. Deglaze the pan: Pour the chicken broth into the hot skillet and scrape up any browned bits. Stir in the remaining 1 tablespoon Cajun seasoning. Pour this mixture over the chicken and vegetables.
  5. Cook low and slow: Cover and cook on Low for 4–5 hours or on High for 2–3 hours, until the chicken is tender and reaches 165°F internally.
  6. Make it creamy: About 20 minutes before serving, remove the chicken to a plate and shred or slice. Add cream cheese, heavy cream, and Parmesan to the slow cooker. Whisk until smooth and melted. Return the chicken to the pot and stir to coat.
  7. Finish and balance: Stir in lemon juice to brighten the sauce. Taste and adjust seasoning—add salt, more Cajun seasoning, or cayenne if you like extra heat.
  8. Serve: Garnish with chopped parsley or green onions. Serve over zucchini noodles, cauliflower rice, or steamed broccoli for a complete keto meal.
