Easy Chicken Tetrazzini

Step 1

Preheat oven to 350°. Cook spaghetti according to package directions. Meanwhile, melt butter in a large Dutch oven over medium-high heat; add green pepper and onion. Cook and stir until vegetables are crisp-tender, 4-5 minutes. Stir in chicken, mushrooms, pimientos, soup, milk, garlic powder and salt. Drain spaghetti; add to pan and toss to coat.

Step 2

Pour into a greased 13x9-in. baking dish. Cover and bake until hot and bubbly, 50-60 minutes. Uncover; sprinkle with cheese. Bake, uncovered, until cheese is melted, about 10 minutes.
