Chicken and Broccoli Casserole

Step 1
Preheat the oven to 350 degrees F (175 degrees C).

Step 2
Melt 1 stick butter in a large frying pan over medium heat. Add onion and garlic and saute until onion is translucent, about 5 minutes.

Step 3
Add flour and stir quickly until it is mixed like Play-Doh®. Quickly add broth, milk, and chicken bouillon; whisk until smooth. Remove from the heat and transfer to a large bowl. Add sour cream and both cheeses; stir until well mixed.

Step 4
Place shredded chicken across the bottom of a 9×13-inch casserole dish. Layer cooked broccoli over the chicken and season with salt and pepper. Pour the cheese mixture over top.

Step 5
Bake, uncovered, in the preheated oven until hot, about 25 minutes.

Step 6
Meanwhile, place crushed cornflakes in a zip-top bag. Add melted butter and seal the bag. Massage with your hands until butter coats all the cornflakes.

Step 7
Remove casserole from the oven and distribute cornflake mixture evenly over the top. Bake for 5 more minutes.
