Preparation
- Preheat your oven to 350°F and prepare a large casserole dish.
- In a large saucepan, bring water to a boil and cook the chopped potatoes for 5-6 minutes.
- Remove the potatoes using a slotted spoon and place them in the casserole dish with cooked chicken.
- Add broccoli to the boiling water and cook for 1 minute, then transfer to the casserole dish.
Cheese Sauce
- In the same saucepan, melt butter over medium-low heat and add minced onion, cooking until soft.
- Stir in flour until combined, then pour in chicken broth and milk, whisking until thickened.
- Add 1 cup shredded cheese to the sauce until melted, then mix in Dijon mustard, salt, pepper, garlic powder, and onion powder.
Combine and Bake
- Pour the cheese sauce over chicken, broccoli, and potatoes, and stir to combine.
- Cover with foil and bake for 20 minutes in preheated oven.
- Combine olive oil and panko breadcrumbs in a bowl. After 20 minutes, uncover the casserole and sprinkle with remaining cheese and breadcrumbs.
- Return to oven and bake uncovered for 10 minutes, until hot and bubbly. Serve and enjoy!
Notes
Flexible baking dish options; standard lasagna pan or a 3.8-quart round casserole dish work well. Warm broth and milk help thicken the sauce faster.
