For the pasta: Preheat oven to 350 degrees. Cook pasta according to package directions. Drain and set aside. Meanwhile, melt butter in a medium saucepan over medium heat. Add 2 tsp. of Red Rocks Hickory Smoke Seasoning and the sage, salt, and pepper. Whisk in flour until mixture is smooth. Slowly whisk in milk, stirring until mixture has thickened. Add cheddar and Parmesan, and stir until cheeses are melted. Remove from heat and stir in crushed tomatoes. Combine sauce and pasta. Pour into a greased 2-quart casserole dish.
For the topping: In a small bowl, thoroughly combine melted butter, bread crumbs, Parmesan, and remaining 1/4 tsp. Red Rocks Hickory Smoke Seasoning. Top pasta with seasoned crumbs and bake until sauce is bubbling and topping is golden brown, about 15 to 20 min.
