How to Make Million Dollar Chicken Spaghetti
Step 1: Prep Your Oven and Dish
Start by preheating your oven to 350°F and lightly greasing a 9×13-inch baking dish. This ensures that your Million Dollar Chicken Spaghetti won’t stick and will bubble up with beautifully crisp edges. Having your dish ready to go makes the assembly a breeze.
Step 2: Cook the Spaghetti
Bring a large pot of salted water to a boil and cook your spaghetti according to package directions until just al dente. You want the noodles to hold up in the casserole, so avoid overcooking. Drain well and set aside while you prepare the sauce.
Step 3: Make the Creamy Sauce
In a large mixing bowl, combine the softened cream cheese, sour cream, cream of chicken soup, drained Rotel, garlic powder, onion powder, salt, and pepper. Stir until everything is completely blended and smooth. This is where your Million Dollar Chicken Spaghetti gets its signature richness and tangy kick!
Step 4: Add Chicken and Cheeses
Fold in the shredded cooked chicken, 1 cup of the cheddar cheese, and the mozzarella cheese. Make sure everything is distributed evenly so every forkful is packed with tender chicken and melty cheese.
Step 5: Combine with Spaghetti
Add your cooked, drained spaghetti directly into the sauce mixture. Toss gently but thoroughly, ensuring each strand is coated in the creamy, cheesy sauce, and the chicken is tucked throughout.
Step 6: Assemble and Top
Pour the entire mixture into your prepared baking dish, spreading it out evenly so every corner gets its share of deliciousness. Sprinkle the remaining ½ cup of cheddar cheese and all of the grated Parmesan evenly over the top for that irresistible cheesy crust.
Step 7: Bake to Golden Perfection
Bake uncovered for 25 to 30 minutes, until the casserole is hot and bubbly and the cheese on top is golden. The aroma alone will have everyone hovering in the kitchen, eager for dinner!
Step 8: Garnish and Serve
If you like, sprinkle chopped fresh parsley over the finished Million Dollar Chicken Spaghetti for a pop of color and a hint of freshness. Serve piping hot and watch the smiles appear!

Creative Ways to Present
To really make this dish special, consider serving it in individual ramekins for a dinner party twist, or spooning it into hollowed-out bell peppers before baking for a colorful, fun presentation. Leftovers also make fantastic packed lunches—just reheat and enjoy!
Make Ahead and Storage
Storing Leftovers
Million Dollar Chicken Spaghetti keeps beautifully in the fridge. Simply cover any leftovers tightly or transfer to an airtight container, and they’ll stay fresh for up to 3 days. The flavors actually deepen overnight, making the next-day meal just as delicious.
Freezing
This casserole is a meal-prepper’s dream. If you want to freeze it, assemble the dish right up to the step before baking. Wrap tightly with foil and freeze for up to 2 months. When you’re ready to enjoy, thaw overnight in the fridge, then bake as directed.
Reheating
To reheat, cover the casserole with foil and warm it in a 350°F oven until heated through, about 20 minutes. For single servings, a quick zap in the microwave works just fine—just add a splash of milk to keep it extra creamy.
FAQs
Can I use other types of pasta instead of spaghetti?
Absolutely! While spaghetti is traditional for Million Dollar Chicken Spaghetti, you can swap in linguine, fettuccine, or even penne if that’s what you have on hand. Just make sure to cook the pasta al dente so it holds up well in the casserole.
How can I make this dish spicier?
For a little extra heat, use hot Rotel instead of the mild version, or add a pinch of crushed red pepper flakes to the sauce. You can also stir in some diced jalapeños if you’re really looking to turn up the spice!
Is it possible to make Million Dollar Chicken Spaghetti gluten-free?
Yes! Simply use your favorite gluten-free spaghetti and ensure that your cream of chicken soup is certified gluten-free. The rest of the ingredients are naturally gluten-free, making it an easy adaptation.
Can I prepare Million Dollar Chicken Spaghetti ahead of time?
Definitely! Assemble the casserole up to a day in advance, cover, and refrigerate. When you’re ready to bake, allow it to come to room temperature while the oven preheats, then bake as usual. It makes weeknight dinners a breeze!
What’s the best way to shred cooked chicken?
The quickest method is to use two forks to pull the chicken into bite-sized pieces. For an even faster trick, pop warm, cooked chicken breasts into a stand mixer with the paddle attachment and mix on low—it shreds in seconds!
