Monterey Chicken Spaghetti Bake

A new twist on America’s favorite pasta!

There are so many different, tried-and-true ways to serve spaghetti that we paused for a moment, wondering if the world needed another version. Of course, it does! This Monterey chicken spaghetti bake left us so satisfied, but one plate was definitely not enough! This dish stands out by combining some familiar ingredients that you probably haven’t had with spaghetti, but have tasted in other comfort meals that we all love – and this dish is no different, it’s so, so good.

We knew that creamy chicken soup, sour cream, and not one, but three kinds of cheeses would complement probably the most famous pasta on the planet. If that wasn’t enough to make this meal amazing, we added shredded, tender roasted chicken and spinach into the mixture, and topped the whole dish with fried onions, which add a salty, satisfying crunch before you get into all that gooey, cheesy goodness underneath.

At first glance, some might say we made a souped-up casserole, but we urge you to try it for yourself and let your taste buds do the talking. Each ingredient in this recipe is delicious on its own, but when they all come together in the oven…we guarantee something beautiful happens; a cheesy, protein-packed casserole of perfection that’ll have everyone hooked!
