Monterey Chicken Spaghetti is the ultimate comfort bake packed with tender chicken sweet spinach and creamy cheese all tucked into a tangle of spaghetti and finished with crispy fried onions on top The savory flavors and crunchy finish make it incredibly satisfying for weeknights or gatherings

I first brought this to a family potluck and even the pickiest cousins went back for seconds It was requested again for Sunday dinner and now it is a monthly staple

Ingredients

  • Spaghetti: use classic durum wheat pasta for a springy bite cook until just al dente
  • Cooked chicken breasts: shred or chop try to use chicken that is juicy and not overcooked for best texture
  • Monterey Jack cheese: brings a creamy melt with a rich flavor shred it fresh if possible
  • Parmesan cheese: adds sharpness and depth opt for real Parmigiano Reggiano
  • Sour cream: gives tang and creaminess use full fat for best richness
  • Egg: helps bind everything together whisk until frothy before mixing in
  • Chopped spinach: adds color nutrition and earthiness squeeze dry after thawing to avoid watery casserole
  • Garlic: fresh garlic gives zing but powder works in a pinch look for plump cloves
  • Cream of chicken soup: for creamy base and a cozy flavor buy a quality brand with low sodium if you can
  • Onion powder: for savory background flavor
  • French fried onions: crunchy salty and totally irresistible add half in the casserole and save half for topping

Step-by-Step Instructions

Cook Spaghetti:
Boil the spaghetti in well salted water following the package directions Stir occasionally to prevent sticking and cook until just al dente Drain well Do not overcook or it will become mushy in the bake
Mix the Filling:
In a large bowl beat the egg until light and foamy This will help the casserole hold together Add the chopped chicken sour cream cream of chicken soup both cheeses well-drained spinach half the fried onions garlic and onion powder Mix until everything is well blended The mixture will be thick and creamy
Combine with Pasta:
Add the drained spaghetti to the bowl with the filling mixture Toss thoroughly until every strand is coated and the chicken and spinach are distributed evenly Be gentle so as not to break the spaghetti
Bake the Casserole:
Grease a 9x13 baking dish with butter or oil Pour in the spaghetti mixture spreading evenly Cover tightly with foil Bake at 350 degrees for 30 minutes so the cheese melts and the flavors blend
Add Crispy Topping:
After 30 minutes remove the foil Sprinkle the remaining fried onions evenly over the top Return to the oven and bake uncovered for another five minutes until the onions are deep golden and super crispy Watch closely to avoid burning

Every time I make this I look forward to the moment when the hot casserole comes bubbling out of the oven and the smell of those crunchy onions fills the kitchen Parmesan is my favorite here because of the nutty tang it gives each bite It reminds me of my grandmother always letting me sneak an extra sprinkle on top

Storage Tips

Let the casserole cool completely before storing Cover tightly with foil or transfer to an airtight container Refrigerate for up to four days For longer storage freeze individual portions wrapped in plastic and foil then reheat in the oven at 350 degrees until hot The fried onion topping does lose a bit of crunch after freezing so I sometimes add a fresh sprinkle before reheating

Ingredient Substitutions

You can swap in rotisserie chicken for convenience or even use canned chicken in a pinch Cottage cheese can replace sour cream for a lighter option Swiss or mozzarella cheese work if you do not have Monterey Jack For a vegetarian twist replace the chicken with sautéed mushrooms and add a pinch more garlic

Serving Suggestions

Pair this spaghetti bake with a crisp green salad dressed in lemony vinaigrette for balance Garlic bread on the side is always welcome To brighten it up spoon a bit of tangy marinara on each plate or toss in a handful of cherry tomatoes before baking
