Monterey Chicken Spaghetti

This monterey chicken spaghetti is packed with spinach and monterey jack cheese for a new chicken casserole recipe the whole family will love.

I had someone email the other day to ask if I happened to be from the midwest. She said she had a hunch.

Now, you guys, I’m pretttttty certain that this hunch was based on the type of food you see on this blog all the time. I didn’t ask her, so I can’t be sure, but it’s a good guess.

Anyway…what type of food is it that I think screams “this girl lives in the middle of the country, surrounded by corn and cows?” Casseroles. Lots and lots of casseroles.

My family especially loves chicken casserole recipes. How about yours?

This chicken casserole recipe is pure comfort food. My kids love the mild monterey jack cheese with chicken in this recipe!

I love them, okay?

I’m always trying new chicken casserole recipes and I’ve hit on a good one right here. It’s a bit of a riff on something I saw in a Taste of Home magazine for Monterey Spaghetti – I’ve added chicken and omitted the Parmesan, because I’m the boss of my life.

This recipe was super easy to toss together and even my youngest ate it, despite all of the green stuff lurking in her noodles. She side-eyed me the whole time, but we made it through dinner without incident.

I really love the Monterey jack cheese in this – it’s mellow and creamy and just plain works. You could swap it out for something with a stronger flavor, like Gruyere or Swiss or maybe even a white cheddar, but I think it’s pretty perfect as it is and I think you’ll like it too!

You know the drill – give this a try, snap a photo, tag me on Instagram, and hashtag it #bunsinmyovenrecipe. I can’t wait to see those gorgeous casseroles coming out of your ovens!
