Ingredients

Scale

  • 1 lb spaghetti noodles

  • 2 tbsp olive oil, divided

  • 1 yellow onion, diced

  • 1 red or green bell pepper, diced

  • 2 (10 oz) cans diced tomatoes with green chilies (like Rotel)

  • 1 (10.5 oz) can cream of mushroom soup

  • 1 (10.5 oz) can cream of chicken soup

  • 2 cups chicken stock

  • 2 cups shredded cheddar cheese

  • 4 oz Velveeta, cubed

  • 2 heaping cups cooked diced or shredded chicken

  • Salt and pepper to taste


Instructions

 

  1. Preheat oven to 350°F.

  2. Cook spaghetti in salted water until just shy of al dente. Reserve ½ cup of pasta water, then drain and toss noodles with 1 tbsp olive oil.

  3. In a large skillet or Dutch oven, heat remaining 1 tbsp olive oil over medium-high heat. Add onion and bell pepper, sauté until onion is soft.

  4. Stir in diced tomatoes with green chilies. Let simmer until most of the liquid is gone.

  5. Add cream of mushroom soup, cream of chicken soup, and chicken stock. Bring to a simmer.

  6. Stir in cheddar cheese and Velveeta until melted and sauce is smooth.

  7. Add in cooked chicken. Season with salt and pepper.

  8. Toss in the spaghetti and stir to coat. Add reserved pasta water if needed to loosen up the sauce.

  9. Pour into a greased 13×9-inch baking dish.

  10. Bake for 30–40 minutes, or until bubbly and golden on top. Let it sit a few minutes before serving.
