Instructions

Step 1: Preheat oven to 375°F (190°C). In a large skillet, heat 1 tbsp olive oil over medium heat. Sauté 2 minced garlic cloves for 30 seconds, then add 1.5 lbs chicken thighs. Cook for 5-6 minutes per side until golden, then transfer to a baking dish.
Step 2: Add 2 cups broccoli florets to the skillet and sauté for 2 minutes. Pour 1 cup milk and 1/2 cup heavy cream into the skillet, stirring to combine. Cook for 3-4 minutes until slightly thickened.
Step 3: Stir in 2 tbsp flour, 1 tsp salt, 1/2 tsp black pepper, and 1 cup grated cheddar cheese. Cook for 2 minutes until the sauce is smooth and bubbly.
Step 4: Pour the cheese sauce over the chicken and broccoli in the baking dish. Bake for 25-30 minutes until the top is golden and bubbly, and the chicken is fully cooked.
Step 5: Let rest for 5 minutes before serving, garnished with additional cheese and fresh parsley.
