Ingredients
• 2 lbs (900g) boneless, skinless chicken thighs
• 2 tbsp (30g) green pesto
• ⅔ lb (300g) cauliflower, cut into florets
• 4 oz (115g) cherry tomatoes, halved
• 7 oz (200g) shredded cheese (mozzarella or Italian blend)
• 3 tbsp (45g) butter
• 1¼ cups (300ml) heavy whipping cream
• 1 large leek, sliced
• ½ tbsp (7.5ml) fresh lemon juice
• Salt and freshly ground black pepper, to taste
Instructions
1. Preheat your oven to 400°F (200°C).
2. In a small bowl, whisk together the heavy cream, pesto, and lemon juice. Season generously with salt and pepper to create the sauce.
3. Pat the chicken thighs dry with a paper towel and season them on all sides with salt and pepper.
4. In a large oven-safe skillet, melt the butter over medium-high heat. Sear the chicken thighs for 2-3 minutes per side until they are lightly golden.
5. Pour the creamy pesto sauce over the chicken in the skillet. (If your skillet isn’t oven-safe, transfer the seared chicken to a baking dish before adding the sauce).
6. Scatter the cauliflower florets, sliced leek, and halved cherry tomatoes around the chicken.
7. Sprinkle the shredded cheese evenly over the entire dish.
8. Bake for 25-30 minutes, or until the chicken is cooked through and the cheese is melted, bubbly, and slightly golden.

Pro Tips
• for the Perfect Casserole
• For a crispier, golden-brown topping, switch the oven to broil for the last 2-3 minutes of cooking. Keep a close eye on it to prevent burning.
• Feel free to substitute broccoli for cauliflower or add a few handfuls of fresh spinach for extra nutrients. Wilt the spinach before adding it to the dish.
• This casserole can be assembled up to 24 hours in advance. Cover and refrigerate, then add 10-15 minutes to the baking time when you’re ready to cook.
• Don’t overcrowd the pan when searing the chicken. Work in batches if necessary to ensure each piece gets a beautiful golden crust.
