- 2 cups shredded cheddar cheese, divided

Crafting Your Million Dollar Chicken Spaghetti: Step-by-Step
Step 1: First things first, let’s get that oven preheated to 350°F. While it’s warming up, grab your trusty 9 x 13 inch baking dish and give it a quick grease. This just helps everything slide out super easily later, you know? It’s like getting a head start, kind of like how a good chicken enchilada casserole gets you excited for dinner.
Step 2: Time to get your spaghetti going! Grab a big pot, fill it with water, toss in a good pinch of salt, and bring it to a rolling boil. Cook your spaghetti according to the package directions, but make sure you pull it out when it’s just ‘al dente’ – you know, still got a little bite to it. We don’t want mushy pasta here! Drain it well and just set it aside for now.
Step 3: Now, let’s build some flavor! Heat up a tablespoon of olive oil in a large skillet over medium heat. Toss in your diced yellow onion and let it get nice and soft, about 4 to 5 minutes. Then, add your minced garlic and cook for just about 30 seconds more until it’s fragrant. Careful not to burn that garlic!
Step 4: Here comes the creamy magic! Pour in the cream of chicken soup, cream of mushroom soup, and that low-sodium chicken broth. Drop in the sour cream and the softened cream cheese. Stir it all around until everything is smooth and looks super luscious. It’s going to smell amazing, almost as rich as a creamy chicken alfredo lasagna!
Step 5: Let’s get this sauce seasoned up! Stir in 1 1/2 cups of that shredded cheddar cheese – save the rest for the top! Add in your Italian seasoning, onion powder, garlic powder, salt, and black pepper. Give it a good mix, and then fold in the drained diced tomatoes. They add a little brightness, which is nice!
Step 6: Now for the star of the show: the chicken and spaghetti! Gently fold your cooked shredded chicken and the drained spaghetti into that glorious creamy sauce. Make sure every strand of pasta and every bit of chicken is coated. It should look so inviting!
Step 7: Time to assemble! Pour this yummy mixture into your prepared baking dish and spread it out evenly. Don’t be shy, get it all in there! Then, sprinkle the remaining 1/2 cup of cheddar cheese all over the top. This is going to melt into this perfect golden-brown crust.
Step 8: Into the oven it goes! Bake it uncovered for about 30 to 35 minutes. You’re looking for it to be bubbly around the edges and that cheese on top to be beautifully melted and maybe even a little golden. It’s going to smell incredible coming out of the oven.

Step 9: The hardest part: waiting! Let it sit for about 10 minutes before you serve it – this allows the sauce to thicken up just a bit more, making it even creamier. Then, sprinkle that fresh chopped parsley over the top for a pop of color and freshness. Dinner is served!

Perfect Pairings for Million Dollar Chicken Spaghetti
This Million Dollar Chicken Spaghetti is so rich and comforting, sometimes a little something *else* is needed to really make the meal sing! Here are a few things I love to serve alongside it:
Simple Green Salad or Broccoli Apple Salad: A crisp, fresh salad cuts right through all that creamy cheese and pasta. The slight sweetness and crunch from a slaw-like salad is just divine!
Roasted Asparagus or Green Beans: A simple side of roasted veggies, maybe with a little lemon zest, adds a nice bit of freshness and a healthy balance. Plus, who doesn’t love a good roasted vegetable?
A Light Fruit Salad: Something refreshing like a watermelon and peach salad provides a lovely sweet and juicy contrast that’s super palate-cleansing after the rich casserole.
Storing and Reheating Your Million Dollar Chicken Spaghetti
Leftovers? Oh, yes! This Million Dollar Chicken Spaghetti is fantastic the next day. Store any extra in an airtight container in the fridge for about 3 to 4 days. When you’re ready to reheat, you have a couple of options. My favorite way to bring back that creamy, bubbly goodness is in the oven: pop it into a 350°F oven for about 15-20 minutes until it’s heated through. If you’re in a super hurry, the microwave works too, just stir it halfway through to make sure it heats evenly. This dish is also great for meal prep; you can assemble the whole thing and just bake it when you’re ready!
Frequently Asked Questions about Million Dollar Chicken Spaghetti
Can I make this Million Dollar Chicken Spaghetti ahead of time?
Absolutely! This is a fantastic make-ahead meal. You can assemble the whole casserole (up to step 7 in the instructions) and cover it tightly with plastic wrap, then refrigerate it for up to 2 days. When you’re ready to bake, just remove the plastic wrap, top with the remaining cheese, and bake as directed, probably adding an extra 5-10 minutes since it’s going in cold. It still comes out wonderfully creamy and delicious, perfect for busy days!
What if I don’t have cream of mushroom soup? Can I substitute it in this creamy chicken spaghetti?
No worries if you’re missing cream of mushroom! The best substitute is another can of cream of chicken soup. So, you’d use two cans of cream of chicken soup instead of one cream of chicken and one cream of mushroom. Some folks also like using a can of cream of celery soup, which works too! It will change the flavor just slightly, but it will still be super creamy and delicious, just like a good creamy macaroni salad.
Can I use a different type of pasta for this baked spaghetti?
You sure can! While spaghetti is traditional and gives it that classic feel, other pasta shapes work great too. Elbow macaroni, penne, rotini, or even shells would be delicious. Just make sure you cook whatever pasta you choose until it’s just al dente, since it will continue to cook in the oven. The sauce is pretty adaptable, so any of your favorite pasta shapes will make this a winner, much like a good creamy tomato spinach pasta.
