Description

A creamy and comforting casserole made with cooked spaghetti, shredded chicken, Monterey Jack cheese, and a deliciously smooth sauce, topped with crispy French fried onions.


Ingredients

Main Ingredients

  • 12 oz Cooked spaghetti (Cooked al dente)
  • 3 cups Shredded cooked chicken (Use rotisserie or baked chicken)
  • 2 cups Shredded Monterey Jack cheese (Reserve some for topping)
  • 1 cup Sour cream (For creaminess)
  • 1 can Cream of chicken soup (Or a homemade white sauce)
  • 10 oz Frozen chopped spinach (Thawed and well drained)
  • 2 cloves Minced garlic (Fresh or jarred)
  • 1 cup Chicken broth (Just a splash to loosen the sauce)
  • 1 tsp Onion powder
  • 1 tsp Paprika
  • 0.5 tsp Salt
  • 0.5 tsp Black pepper
  • 2 tbsp Butter or olive oil
  • 1 bag French fried onions (For topping)


Instructions

Preparation

  1. Preheat the oven to 350°F (175°C).
  2. Bring a large pot of salted water to a boil and cook the spaghetti until just tender. Drain well.
  3. In a big mixing bowl, combine the soup or white sauce, sour cream, a splash of chicken broth, and one cup of shredded Monterey Jack. Stir in the minced garlic, onion powder, paprika, salt, and pepper.
  4. Fold in the chopped spinach and shredded chicken. Adjust seasoning to taste.
  5. Add the spaghetti and toss until every strand is coated. If too thick, add more broth; if too loose, stir in more cheese.

Baking

  1. Transfer to a greased casserole dish and sprinkle more cheese on top. Reserve the French fried onions for the last few minutes of baking.
  2. Cover the casserole with foil and bake for 25-30 minutes until warmed through and the edges are gently bubbling.
  3. Uncover, top with French fried onions, and bake for another 8-10 minutes until bubbly and golden.
  4. Let it rest for 5-10 minutes before serving.

Notes

For meal prep, assemble in advance but add the fried onions just before baking. Freeze without fried onions and thaw overnight before baking.
