When I was in the Navy, a co-worker's wife shared this recipe with me. I’ve tweaked it over the years, but it still brings back memories of my "family" away from home. —Yvonne Cook, Haskins, Ohio
Preheat oven to 350°. Cook noodles according to package directions; drain. Transfer to a shallow 3-qt. or 13x9-in. baking dish coated with cooking spray.
Meanwhile, in a large nonstick skillet, heat butter over medium-high heat. Add onion; cook and stir until tender. In a small bowl, whisk cornstarch, milk and seasonings until smooth; stir into pan. Stir in broth. Bring to a boil; cook and stir until thickened, about 2 minutes. Stir in 3/4 cup cheese until melted; stir in broccoli and tuna.
Spoon over noodles; mix well. Sprinkle with remaining cheese. Toss bread crumbs with melted butter; sprinkle over casserole. Bake, covered, 45 minutes. Uncover and bake until cheese is melted, 15-20 minutes longer.
