Ingredients 

  • 2½ - 3 cups cooked chicken breast shredded or chopped
  • 1 pound spaghetti pasta
  • 10 ounce Rotel original undrained (for GF use a gluten free brand)
  • 16 ounces Mexican Velveeta cubed (or use original)
  • 10.5 ounce cream of mushroom soup
  • 10.5 ounce cream of chicken soup
  • 1 cup sour cream
  • 1 teaspoon onion powder
  • 1 teaspoon garlic powder
  • ½ teaspoon black pepper
  • 1 to 1 ½ cup shredded cheddar cheese or favorite cheese blend

Instructions

  • Cook pasta, in salted water, according to package instructions to al dente, drain.
  • Prepare 9 x 13 casserole dish by spraying lightly with cooking spray.
  • Preheat oven to 350℉.
  • In a large pot, add the Rotel and cubed Velveeta. Then pour in the cream of mushroom, cream of chicken, and sour cream. Add in the onion powder, garlic powder, and pepper. Keep stirring the mixture until it is smooth and melted.
  • Add in the shredded or chopped chicken and noodles to the pot and stir it until combined. Taste and add salt to taste if desired.
  • Pour into prepared baking dish and top with shredded cheese and bake 30 minutes or until golden and bubbly.

Notes

I don't add salt to this recipe (except in the pasta water) because the canned soups already have plenty. But you can salt to taste.

Gluten-Free Chicken Spaghetti Pasta: 

Use gluten-free cream of mushroom and cream of chicken soup along with gluten-free spaghetti. Find a GF can of diced tomatoes and green chiles. Great Value Melt' n Dip Cheese shows GF (green on the Fig app). Block Velveeta (not the shells-and-cheese kind) is said to be considered GF, though it isn't certified gluten-free. Kraft says they disclose allergen ingredients and it only lists Milk, however it is yellow on the fig app as of the date of this post. Always check all labels carefully, since ingredients can change.
