Step 1: Season the Chicken
Place the chicken breasts on a plate and sprinkle with Cajun seasoning, salt, and freshly ground black pepper.
Drizzle over the fresh lime juice and rub the seasoning gently over the chicken to coat evenly.
Step 2: Lightly Brown the Chicken
Heat a large non-stick frying pan over medium-high heat and lightly coat with cooking spray.
Add the seasoned chicken breasts and cook for approximately 2–3 minutes on each side, until lightly golden.
The chicken does not need to be fully cooked at this stage, as it will finish cooking in the slow cooker.
Step 3: Prepare the Potatoes
Wash the baby potatoes thoroughly and cut any larger ones in half.
Place the potatoes in the bottom of the slow cooker.
Add the crushed garlic, dried rosemary, red pesto, and light buttery spread.
Stir gently to coat the potatoes with the seasonings.
Step 4: Add the Chicken
Arrange the browned chicken breasts over the seasoned potatoes.
Sprinkle the grated Parmesan evenly over the chicken and potatoes.
If your slow cooker requires additional liquid, add approximately 75ml water or chicken stock around the edges.
Step 5: Slow Cook
Cover with the lid and cook on High for approximately 3 hours, or until the potatoes are fork-tender and the chicken is fully cooked.
Cooking times may vary depending on the size of the chicken breasts and your slow cooker.
Check that the thickest part of the chicken reaches an internal temperature of 74°C (165°F).
Step 6: Finish the Dish
Once cooked, gently stir the potatoes through the flavorful cooking juices.
Spoon a little of the garlic, pesto, and Parmesan sauce over the chicken.
Taste and adjust the seasoning if needed.
Step 7: Serve
Divide the chicken and potatoes between four plates.
Serve with steamed tenderstem broccoli and roasted cherry tomatoes.
Sprinkle with a little extra Parmesan if desired, remembering that additional cheese changes the nutritional values.
Tips for the Best Pesto Parmesan Chicken
