Ingredients

  • Spaghetti 16 ounces, snapped into smaller sections
  • Chicken cooked and either diced or shredded (4 cups)
  • Green bell pepper finely chopped (½ cup)
  • Fresh celery finely chopped (½ cup)
  • Fresh onion finely chopped (½ cup)
  • Diced pimentos from a 4 oz jar or Rotel diced tomatoes with green chilies (from a 10 oz can) - ensure they're well-drained
  • Cream of mushroom soup two 10.5 oz cans, undiluted
  • Chicken broth 2 cups
  • Grated cheddar cheese 1 ½ cups, portioned
  • Velveeta cheese finely diced or grated (1 cup)
  • Salt and pepper for seasoning

Instructions

  • Begin by setting your oven to 350°F. Grease a 9 x 13-inch baking dish.
  • Boil the spaghetti in a pot filled with salted water. Follow the package's instructions for al dente texture. Drain and keep aside.
  • In the pot, combine chicken, vegetables, pimentos or Rotel, soup, broth, half of the cheddar, and Velveeta. Mix thoroughly. Adjust seasoning with salt and pepper.
  • Empty the pot's contents into the baking dish. Top off with the remaining cheddar.
  • Uncovered, bake for about 45 minutes. The top should be bubbly with the cheese perfectly melted.
  • Serve hot!

Notes

  • Opt for whole wheat spaghetti for a healthier twist.
  • Craving a crunchy top? Use a Ritz cracker mix: combine one sleeve of crushed Ritz crackers (about 1½ cups) with 4 tablespoons of melted butter. Spread this mix over the casserole pre-bake.
  • Cheese swap: Feel free to experiment with Monterey Jack, Pepper Jack, or even Mozzarella.
  • Soup variants: Try the cream of chicken or cream of celery soups.
  • Aim for perfectly al dente spaghetti to avoid overcooked pasta post-baking.
  • For quick preparation, use rotisserie chicken. Alternatively, boil chicken parts of your choice and shred them.
  • A sprinkle of fresh parsley enhances the dish's presentation.
