Ingredients You’ll Need

The ingredients for Monterey Chicken Spaghetti are simple but essential; each one brings something special to the table, whether it’s flavor, texture, or a splash of color. They’re easy to find, budget-friendly, and combine in a way that tastes so much more than the sum of its parts!

Cooked chicken: Rotisserie or leftover roast chicken work perfectly for rich, tender protein.
Spaghetti: Classic long noodles that soak up the creamy sauce, but any pasta will do.
Olive oil: Helps sauté veggies for a subtle, savory foundation.
Onion: Adds a touch of sweetness and depth to the dish.
Bell pepper: For bursts of color and a faint sweetness in every bite.
Mushrooms: Bring umami earthiness to balance the creamy sauce.
Cream of chicken soup: The key to a velvety sauce with loads of flavor.
Sour cream: Gives the sauce its tangy richness and silky texture.
Monterey Jack cheese: The star cheese—melts beautifully for ultimate gooeyness!
Cheddar cheese: Lends a sharp bite and gorgeous golden color.
Garlic powder: Adds a mellow, savory background flavor.
Onion powder: Rounds out the savory notes and boosts the overall flavor.
Salt and pepper: Essential for seasoning—taste as you go.
Milk (or chicken broth): Loosens the sauce just enough; broth adds extra flavor.
Fresh parsley (optional): For a fresh, bright garnish and pop of green.

How to Make Monterey Chicken Spaghetti

Step 1: Cook the Pasta

Get things rolling by boiling your spaghetti according to the package instructions. Be sure to salt your water for extra flavor! Once the noodles are al dente, drain them and set them aside—they’ll soon be smothered in saucy goodness.

Step 2: Sauté the Vegetables

Heat your olive oil in a large skillet over medium heat. Toss in the onion, bell pepper, and mushrooms all at once. Sauté these until they’re soft, fragrant, and just starting to turn golden. This step gives your Monterey Chicken Spaghetti its signature base of sweet and savory notes.

Step 3: Make the Creamy Sauce

Now, stir in the cream of chicken soup, sour cream, garlic powder, onion powder, and your milk or chicken broth. Mix everything until it’s smooth and starting to bubble gently. This sauce will hug every noodle and chicken chunk, creating that dreamy creamy texture.

Step 4: Add Chicken and Cheese

Next, fold in your shredded chicken and half the Monterey Jack cheese. Stir well so the cheese melts right into the sauce and the chicken gets totally coated. Let it bubble for another couple of minutes to warm everything through and blend the flavors.

Step 5: Combine with Pasta

Add your cooked, drained spaghetti to the large skillet and toss until every strand is slick with the cheesy, chicken-packed sauce. This is where the Monterey Chicken Spaghetti starts to come together into its final, irresistible form.

Step 6: Optional Baking Step

If you love a bubbly, golden top, preheat your oven to 350°F (175°C). Transfer the mixture to a greased 9×13-inch baking dish. Sprinkle the rest of the Monterey Jack and all the cheddar cheese over the top for that craveable melted cheese finish.

Step 7: Bake Until Bubbly

Pop the dish into your preheated oven and bake for 20–25 minutes, until the cheese is golden and melty, and the whole kitchen smells like Monterey Chicken Spaghetti heaven. If you’re short on time, you can skip this—just serve straight from the skillet!

Step 8: Serve and Enjoy

Scatter fresh parsley over the top for a splash of green, and serve piping hot. Be ready for serious compliments and empty plates.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, Monterey Chicken Spaghetti keeps well covered in the fridge for up to 3 days. Make sure it’s cooled to room temperature before popping it into an airtight container.

Freezing

Monterey Chicken Spaghetti is freezer-friendly! Assemble the casserole up until the baking step, wrap it tightly, and stash in the freezer for up to three months. Thaw overnight in the fridge before baking as directed.

Reheating

For best results, reheat Monterey Chicken Spaghetti in the oven, covered with foil at 350°F until warm throughout. You can also reheat single servings in the microwave, adding a splash of milk or broth to keep the sauce creamy.

FAQs

Can I use a different type of cheese in Monterey Chicken Spaghetti?

Absolutely! While Monterey Jack and cheddar are classic, feel free to try mozzarella for extra stretch or pepper jack for a little heat. Just be sure the cheese melts well for that signature creamy texture.

Is there a gluten-free option?

Yes! Simply swap the regular spaghetti for your favorite gluten-free brand, and double-check your cream of chicken soup for any gluten-containing thickeners.

Can I make Monterey Chicken Spaghetti ahead of time?

You bet—assemble everything up until baking, then cover and refrigerate for up to 24 hours. When you’re ready to eat, just bake as usual, adding an extra few minutes if it’s cold from the fridge.

What can I use instead of cream of chicken soup?

If you prefer, make a quick homemade sauce by whisking chicken broth, a bit of flour, and a splash of milk with some sautéed onions and seasonings. It’ll have the same creamy effect without the can.

What proteins can I substitute for chicken?

Turkey works well, especially around the holidays. For a vegetarian twist, try white beans or sautéed mushrooms to keep things hearty. The sauce and cheese play well with lots of different proteins!
