Equipment

  • 1 large pot
  • 1 9x13 baking dish
  • 1 oven
  • 1 wooden spoon or spatula

Ingredients
  

  • 1 lb spaghetti
  • 2 cups milk
  • 8 oz queso blanco Velveeta or regular Velveeta
  • 1 cup shredded cheddar cheese divided
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup sour cream
  • 2 10.5 oz cans cream of chicken soup
  • 1 10 oz can Rotel (diced tomatoes and green chiles)
  • 3 cups cooked chicken e.g., rotisserie chicken
  • 3-4 tablespoons French's fried onions
  • Salt and pepper to taste
  • Garlic powder to taste
  • Onion powder to taste

Instructions
 

  • Break the spaghetti in half and boil for about 2 minutes less than the package instructions until al dente. Drain and return pasta to the pot.
  • Add milk, cream of chicken soup, Rotel, Velveeta, half of the cheddar cheese, mozzarella cheese, sour cream, and cooked chicken to the pot.
  • Stir over medium heat continuously until all cheeses melt and the mixture is smooth. Season with salt, pepper, garlic powder, and onion powder to taste.
  • Spread the mixture evenly into a greased 9x13 baking dish.
  • Top with remaining cheddar cheese and French's fried onions.
  • Bake in a preheated oven at 350°F for about 15 minutes until cheese melts and onions turn brown.

Notes

  • Cook pasta slightly underdone to avoid overcooking during baking.
  • Use rotisserie chicken for convenience.
  • Store leftovers in the fridge up to 3 days.
  • Reheat covered to retain moisture.
