Ingredients You’ll Need

One of the joys of making Monterey Chicken Spaghetti is how effortlessly the ingredients blend into something irresistible. Every component has a job to do—from adding creaminess to delivering that signature pop of flavor and color. Here’s everything you’ll need, along with some quick tips to make your dish shine:

Cooked chicken, shredded: Rotisserie chicken works wonders for rich flavor and convenience.
Spaghetti (or any pasta): Classic spaghetti brings the perfect amount of bite, but feel free to play with different shapes.
Olive oil: This adds a hint of richness as you sauté the veggies.
Onion, chopped: A must for savoriness and a little sweetness when softened.
Bell pepper, chopped: Use any color for a burst of freshness and color (I love using red or yellow!).
Mushrooms, sliced: They soak up the sauce beautifully and add deep earthy flavor.
Cream of chicken soup: The secret shortcut to a creamy, velvety sauce.
Sour cream: This brings tangy richness and a luxurious texture to the sauce.
Monterey Jack cheese, shredded: Melty, mild, and essential for the gooey topping.
Cheddar cheese, shredded: For a touch of sharpness and golden color on top.
Garlic powder: Adds mellow, garlicky depth without overpowering.
Onion powder: Delivers an extra boost of onion flavor in every bite.
Salt and pepper: Essential for seasoning and bringing it all together.
Milk (or chicken broth): Helps make the sauce silky—use broth if you like a lighter feel.
Fresh parsley, chopped (optional): For a pop of color and freshness as a final flourish.

How to Make Monterey Chicken Spaghetti

Step 1: Cook the Pasta

Start by boiling your spaghetti according to the package instructions until al dente. Don’t forget to salt the water—a little goes a long way in building flavor. Once cooked, drain the pasta and set it aside. If you want to prevent sticking while you prep the rest, give it a quick toss with a splash of olive oil.

Step 2: Sauté the Veggies

In a large skillet, heat the olive oil over medium heat. Add the chopped onion, bell pepper, and sliced mushrooms. Sauté for 5 to 7 minutes, stirring occasionally, until the vegetables soften and take on a touch of golden color. This step releases sweetness and maximizes the flavor base of your Monterey Chicken Spaghetti.

Step 3: Make the Creamy Sauce

Reduce the heat a little and stir in the cream of chicken soup, sour cream, garlic powder, onion powder, and your milk or broth. Whisk it all together right in the skillet, and let it simmer for 2 to 3 minutes until the sauce is completely smooth and gently warmed through. Take a second to inhale—you’ll already smell the comfort coming together.

Step 4: Add Chicken and Cheese

Mix the shredded chicken into the sauce, along with half of the Monterey Jack cheese. Let everything heat and meld for another 2 to 3 minutes, until the cheese melts and the chicken is nice and warm. The mixture should be decadently creamy at this point!

Step 5: Combine with Pasta

Toss the cooked pasta directly into the skillet of sauce. Use tongs or a large spoon to coat every strand in that luscious, cheesy goodness—this is where Monterey Chicken Spaghetti gets its signature pull-apart texture.

Step 6: Optional Baking Step

If you love a bubbly, cheesy finish, transfer the pasta mixture into a greased 9×13-inch baking dish. Sprinkle the remaining Monterey Jack and all the cheddar cheese evenly over the top. Bake at 350°F (175°C) for 20 to 25 minutes, until the cheese is melted and the edges are joyfully bubbly.

Step 7: Serve and Enjoy

Finish your Monterey Chicken Spaghetti with a generous sprinkle of fresh parsley. Serve it warm, scoop up a hearty serving, and dig in while the cheese is still gloriously gooey.

How to Serve Monterey Chicken Spaghetti

Garnishes

A handful of chopped fresh parsley instantly brightens the finished Monterey Chicken Spaghetti, adding herbal freshness and a pop of green to the golden, creamy dish. You could also try thinly sliced green onions, a dash of smoked paprika, or even crispy breadcrumbs if you love a bit of crunch.

Side Dishes

This spaghetti is hearty but pairs beautifully with lighter, crunchy sides like a tossed green salad or simply steamed broccoli. Garlic bread, of course, is always welcome, offering the perfect vehicle for catching those last bits of cheesy sauce at the bottom of your plate!

Creative Ways to Present

Bring Monterey Chicken Spaghetti to the spotlight by portioning it into individual ramekins for a dinner party, or top it with a few sliced jalapeños for a little kick. For a family-style feast, serve it right from the skillet at the table for an inviting, rustic touch.

Make Ahead and Storage

Storing Leftovers

Leftover Monterey Chicken Spaghetti holds up beautifully in the fridge for up to three days. Let it cool completely, then cover the baking dish tightly or transfer portions to airtight containers. The flavors deepen overnight—lucky you!

Freezing

If you want to save some for later, this dish freezes like a charm (just leave off fresh garnishes until serving). Wrap it well in foil or store in freezer-safe containers. It will keep in the freezer for up to two months.

Reheating

To bring reheated Monterey Chicken Spaghetti back to its gooey glory, bake covered at 350°F until warmed through, or heat individual portions in the microwave. Add a splash of milk when reheating to keep everything creamy and prevent drying out.

FAQs

Can I use rotisserie chicken?

Absolutely! Rotisserie chicken is a phenomenal time-saver and infuses Monterey Chicken Spaghetti with rich, savory flavor and juicy texture. Just shred and toss it in when the recipe calls for cooked chicken.

Can I make this without mushrooms?

Yes! If you’re not a fan of mushrooms or simply don’t have any on hand, you can leave them out or replace them with extra bell peppers, zucchini, or even some chopped spinach for a nutritional boost.

Is this recipe spicy?

Not at all—it’s super family friendly. But if you’re craving a little heat, try stirring in some diced jalapeños or sprinkle a pinch of crushed red pepper into the sauce.

What’s the best way to reheat leftovers?

For maximum creaminess, reheat leftover Monterey Chicken Spaghetti gently in a covered baking dish at 350°F or in the microwave in short bursts. Adding a splash of milk or broth before reheating can help restore that just-made texture.

Can I prepare it ahead and bake later?

Definitely! Assemble the dish and stop just before baking. Cover tightly and refrigerate for up to 24 hours. Add a few extra minutes to the bake time straight from the fridge and you’re set.
