Kid-Friendly Mac and Cheese

Preheat oven to 350 degrees, and prepare an 8x8-inch baking dish by spraying it with cooking spray. 

Place the French bread cube in a single layer on a rimmed baking sheet. Drizzle with butter and toss to coat; set aside. 

Melt butter in a large saucepan over medium heat. Whisk in flour and mustard. 

Slowly whisk in milk and continue to cook until thickens. 

Mix in 2 cups of the shredded cheese, salt, pepper, and Worcestershire sauce. Add more salt if needed. 

Cook and stir until cheese melts. Remove from heat and mix in the macaroni, stirring until thoroughly combined. 

Pour into prepared baking dish. Sprinkle 1/2 the remaining cheese on top. 

Cover with buttered bread cubes and sprinkle with remaining cheese. Bake for 30 minutes or until golden brown.
