Ingredients
Method
- Melt the 3 tbsp butter in a medium saucepan over medium heat. Whisk in the flour and cook for 1 to 2 minutes. Slowly whisk in the milk and broth, then add the onion powder, garlic powder, salt, and pepper. Keep whisking until the sauce thickens, about 4 to 5 minutes.
- Remove from heat and fold in the chicken and frozen vegetables until evenly coated.
- Preheat the oven to 375°F (190°C) and grease a 9x13-inch baking dish. Spread the chicken mixture in the dish. In a small bowl, toss the panko with the melted butter and Parmesan, then sprinkle over the casserole.
- Bake for 25 to 30 minutes until the topping is deep golden and the sauce bubbles. Let rest 5 minutes before serving.
Notes
If using rotisserie chicken, you’ll need about half a chicken to get 3 cups. The frozen peas and carrots go straight from the freezer to the pan, no thawing needed.
