Better Broccoli and Cheese Casserole

I was craving the church potluck version of Broccoli Cheese casserole, but not the pound of butter and Velveeta, when I happened upon this lighter version

Ingredients:
2 (10 ounce) packages frozen chopped broccoli
1/2 teaspoon minced garlic
5 tablespoons butter, divided
2 tablespoons flour
1 cup milk
1/2 teaspoon salt
1/8 teaspoon pepper
1 (3 ounce) package cream cheese, softened
3/4 cup shredded cheddar cheese
3/4 cup crushed Ritz crackers

Directions:

• Place broccoli in greased one quart baking dish. Set aside
• Melt 2 tablespoons butter in pan over low heat; add flour and stir until smooth
• Gradually add milk and cook over medium heat, stirring until thick and bubbly
• Add salt, pepper and cream cheese, stirring until well combined.  Add half the cheddar cheese.
• Pour sauce over broccoli and sprinkle with remaining cheese
• Melt remaining butter and combine with cracker crumbs; Sprinkle over casserole
• Bake at 350 degrees for 40 minutes until thoroughly heated
