How to Make Monterey Chicken Spaghetti
Step 1: Preheat & Prep
Set your oven to 350ºF and lightly spray a 9×13-inch baking dish. (No one wants sticky noodles.)
Step 2: Boil That Pasta
Cook your spaghetti according to package directions. Drain it well—no one likes a watery casserole.
Step 3: Mix the Magic
In a large bowl, combine:
- Your cooked chicken
- Cream of chicken soup
- Sour cream
- Drained spinach
- 1 cup of the cheese
- Minced garlic
- And half the can of French fried onions
Give it a good stir until it’s creamy and dreamy.
Step 4: Stir in the Spaghetti
Fold your pasta into the chicken mixture. Think of it as a warm, cheesy hug in a bowl.
Step 5: Assemble & Top
Pour it all into your prepared baking dish. Sprinkle the rest of the cheese and those heavenly onions on top. You know—the golden, crispy kind that makes everything better.
Step 6: Bake Away
Pop it in the oven for 40 to 50 minutes, uncovered, until bubbly and beautifully golden.
Tips from My Kitchen to Yours
- Chicken Shortcut: Rotisserie chicken is your best friend here. Quick, flavorful, and no extra cooking.
- Spinach Secrets: Really squeeze out the moisture from the spinach or it’ll water down the sauce.
- Make-Ahead Magic: Prep the entire dish, cover, and refrigerate up to 24 hours ahead. Bake when ready—just add 5–10 extra minutes to the cook time.
- Want heat? Add a pinch of red pepper flakes or a few dashes of hot sauce to the mix.

A Little Story from My Table
This Monterey Chicken Spaghetti became a weeknight lifesaver back when my twins were toddlers and I had approximately 17 minutes to get dinner on the table between meltdowns and bath time. One bite, and they were quiet (a miracle). My husband went back for thirds. And I? I finally got to finish a meal sitting down. It’s been a regular in our rotation ever since.
FAQs: Let’s Answer Your Burning Questions
Can I use a different pasta?
Absolutely! Penne or rotini would work great if that’s what you have on hand.
Can I make this Monterey Chicken Spaghetti recipe gluten-free?
Yes! Just swap in gluten-free pasta and check your soup and onions for gluten-friendly labels.
How should I store leftovers?
Cover tightly and refrigerate for up to 4 days. Reheat in the oven or microwave. It’s just as dreamy the next day—maybe even more so.
Can I freeze it?
Definitely. Assemble it, wrap it well, and freeze before baking. When you’re ready, thaw overnight in the fridge and bake as usual (add about 10 minutes to cook time).
What should I pair with Monterey Chicken?
Great question! Since this dish is creamy and rich, I love serving it with something light and crisp on the side—like a green salad with vinaigrette or some roasted vegetables. Garlic bread or Texas toast is also a hit if you’re leaning into full-on comfort food mode (no judgment here!).
Is Monterey Jack cheese good on spaghetti?
Oh yes—Monterey Jack is a melty, mild cheese that adds just the right amount of creaminess without overpowering the dish. It plays super well with the other ingredients, especially in this casserole-style spaghetti. It’s basically the glue that holds all the deliciousness together.
Conclusion
This Monterey Chicken Spaghetti recipe is creamy comfort at its finest. It’s the kind of dish you’ll crave on chilly nights, hectic weekdays, or whenever your soul just needs a little cheesy TLC. Bonus: it feeds a crowd and tastes like something you’d get at a cozy family-style restaurant. Go ahead—make it tonight. Your kitchen is about to smell amazing.
