How to Make One-Pan Chicken Bake
Preheat the oven to 180°C fan (200°C/400°F/Gas Mark 6). This ensures your dish cooks evenly and perfectly every time, creating that golden, roasted finish.
Season chicken thighs by cutting them into thirds, and sprinkle with parsley, thyme, salt, and pepper. This simple step infuses the meat with delightful flavor!
Sear the chicken in a hot pan with low-calorie oil spray until golden brown, about 5-7 minutes. This enhances flavor and locks in juiciness; then set the chicken aside.
Melt butter in the same pan and add the sliced onion, diced butternut squash, and paprika; cook until the squash softens, around 6-8 minutes. Don’t forget to deglaze with broth for extra flavor!
Add leeks and chopped garlic to the pan; sauté until the leeks soften and the squash is tender, about 5-8 minutes more. The aroma will be irresistible!
Combine the veggie mixture in a large baking dish, placing the seared chicken on top. Pour any remaining juices and broth over everything to keep it moist.
Sprinkle parmesan cheese over the chicken and cover the dish with foil. Bake for 15 minutes; this creates a steamy environment for tender chicken.
Uncover and bake for another 15 minutes until cooked through and golden brown. If you prefer a crispy top, broil for a few minutes at the end!
Garnish with fresh parsley leaves, season to taste, and serve warm. Enjoy the heartwarming flavors brought together in this delightful bake!
Optional: Serve with crusty bread to soak up the delicious juices.
