Perfecting Chicken Divan Part Two

My recipe for Chicken Divan:
1 large cooked chicken breast, skinless, boneless, shredded
1 head of fresh broccoli, cut into small pieces, including the stem which I peel first
2 Tbsp. butter
2 Tbsp. flour
2 cups milk
Sharp Cheddar cheese, shredded, to taste. I bought slices from my local deli that weighed in at .18lb, it was four slices
Curry powder, pepper, salt, to taste
Lemon juice, to taste
Shredded Cheddar cheese to top

Steam the broccoli until al dente. Place in the bottom of a 9x9 or 8x8 baking pan. Place shredded chicken on top. In a medium saucepan, melt butter, add flour and whisk for a couple minutes over medium heat. Slowly add milk in 1/2 cup increments, stirring to combine after each addition. Bring to a boil and whisk constantly until thickened. Remove pan from heat and add cheese, seasonings and lemon juice and whisk to melt and mix. Adjust to taste. Pour over mixture in pan and heat in 350 degree oven for 45 minutes to an hour until bubbly and browning on top. Top with more shredded cheese and allow to melt. Serve. Leftovers can be frozen and thawed out with no real difference in texture or taste. Makes 4 servings.
Note: The original recipe uses a breadcrumb topping, which I have never cared for. I choose to leave it off, but feel free to make one for it if you wish. I would recommend panko instead of the normal ones if I was going to.
