Baked Tomato Mac N Cheese Casserole

Preheat oven to 350 degrees F (175 degrees C). Butter a baking dish.

Bring a large pot of lightly salted water to a boil. Cook elbow macaroni in the boiling water, stirring occasionally until cooked through but firm to the bite, 8 minutes; drain, return macaroni to pot, and stir tomatoes into the macaroni. Cook over medium heat until the macaroni absorbs some of the liquid from the tomatoes, about 4 minutes. Remove from heat.

Melt butter in a large saucepan over medium-high heat. Stir flour into melted butter and cook until bubbly, 1 to 2 minutes. Slowly stream half-and-half and chicken broth into the butter mixture while stirring. Bring the mixture to a boil and continue to cook while stirring continually until thickened and bubbly, 2 to 3 minutes.

Remove saucepan from heat. Melt mild Cheddar cheese and sharp Cheddar cheese into the butter mixture one handful at a time, stirring to incorporate each addition before adding the next. Season the cheese mixture with pepper and pour over the macaroni; stir to coat pasta evenly. Transfer the mixture to the prepared baking dish and top with crushed crackers.

Bake in preheated oven until crust is golden brown and the liquid is bubbling, 15 to 20 minutes. Cool 10 minutes before serving.
