Plus, most of these are ingredients you might already have in your fridge and pantry.

- Olive oil: For sautéing veggies and adding that subtle fruity touch.
- Onion: Adds sweetness and a bit of crunch when diced fine.
- Red bell pepper: Gives a fresh, colorful sweetness that balances the creamy sauce.

- Vegetarian option: Skip the chicken and add more veggies like mushrooms, zucchini, or spinach for a meatless version that’s just as satisfying.
- Different cheeses: Try pepper jack or gouda in place of cheddar and mozzarella for a smoky or spicy flair.
- Gluten-free: Use gluten-free pasta and cream soup to tailor it for gluten sensitivity.
How to Make Creamy Chicken Spaghetti Bake Recipe
Step 1: Cook the Pasta Just Right
Start by boiling your spaghetti according to the package directions, aiming for al dente texture—usually a minute or two less than fully soft. It’s important because the pasta will finish cooking in the oven, so you don’t want it mushy. Once cooked, drain and set aside.
Step 2: Sauté Your Veggies to Tender
Heat up the olive oil in a large skillet. Toss in diced onions and red bell peppers, letting them soften over medium-high heat until they’re tender and fragrant—about 5 minutes. This step brings out their natural sweetness, which balances the creamy cheese and chicken perfectly.
Step 3: Build Your Creamy Sauce
Add the drained can of Rotel into the skillet with the veggies, stirring to combine. Next, mix in the cream of mushroom soup and softened cream cheese to create that luscious creamy base. Pour in chicken broth and milk, then season with oregano, basil, garlic powder, salt, and pepper. Stir everything together until the cream cheese has melted and you have a smooth sauce.
Step 4: Combine Pasta, Chicken, and Cheese
Now, fold cooked spaghetti and shredded chicken right into your creamy sauce. Stir in the sharp cheddar cheese until it’s evenly distributed throughout the mixture. This ensures cheesy goodness in every bite before it bakes.
Step 5: Bake to Bubbly Perfection
Transfer your chicken spaghetti mixture into a sprayed 9×13 casserole dish and smooth it out evenly. Top generously with mozzarella cheese for that gorgeous golden crust. Bake in a preheated 350°F oven for about 25-30 minutes, or until you see the cheese bubbling and getting nicely browned around the edges.
Step 6: Garnish and Serve
Pull it out from the oven and let it sit a few minutes before serving. I like to sprinkle chopped green onions or fresh parsley on top for color and a fresh pop of flavor. It’s such a welcoming dish that everyone smiles when you bring it to the table.
Pro Tips for Making Creamy Chicken Spaghetti Bake Recipe
- Don’t overcook the spaghetti: Leaving it slightly firm means it won’t get mushy baking in the sauce.
- Use softened cream cheese: This makes stirring it into the sauce so much easier and prevents lumps.
- Drain your Rotel well: Too much liquid can make the bake watery—drain off the excess before adding.
- Let it rest before serving: It helps the bake set for cleaner slices and lets flavors meld beautifully.
How to Serve Creamy Chicken Spaghetti Bake Recipe

Garnishes
Green onions and fresh parsley are my go-to garnishes; they add a burst of color and fresh, mild flavor that cuts through the richness wonderfully. Sometimes, I even toss a sprinkle of crushed red pepper flakes on top for a subtle heat that wakes up the dish.
Side Dishes
I usually pair this Creamy Chicken Spaghetti Bake Recipe with a crisp green salad or steamed broccoli to balance all that creamy goodness. Garlic bread or soft dinner rolls also complement the meal perfectly for soaking up any extra sauce.
Creative Ways to Present
For special occasions, I’ve served this bake in individual ramekins with a sprinkle of extra cheese on top for a fancy, personalized touch. You can also garnish with fresh basil leaves or a drizzle of good olive oil for that restaurant-style feel at home.
Make Ahead and Storage
Storing Leftovers
Leftovers keep beautifully in an airtight container in the fridge for up to 3 days. I like to cover the leftovers tightly to prevent drying out and always make sure to cool the bake fully before refrigerating.
Freezing
This Creamy Chicken Spaghetti Bake Recipe freezes really well! I usually prep the whole casserole but stop before baking. Then I cover it tightly with foil and freeze. When ready, bake it straight from frozen, adding around 20 extra minutes to the bake time.
Reheating
Reheat leftovers in the oven at 350°F covered with foil to keep moisture in, usually about 20 minutes. Microwave works too, but I prefer the oven to preserve the nice texture of the pasta and melted cheese.
FAQs
-
Can I use different types of pasta for the Creamy Chicken Spaghetti Bake Recipe?
Absolutely! While spaghetti is traditional here, you can substitute with penne, rotini, or even elbow macaroni. Just adjust the cooking time to ensure the pasta is al dente before baking.
-
What can I use instead of cream of mushroom soup?
If you don’t love mushrooms or prefer a lighter option, cream of chicken or cream of celery soup works well too. You can even make a simple homemade cream sauce using butter, flour, milk, and broth.
-
Is this recipe freezer-friendly?
Yes! You can freeze the unbaked casserole by wrapping it tightly in foil or plastic wrap. When ready, bake it from frozen, allowing extra time for thorough heating.
-
Can I make this recipe dairy-free?
For a dairy-free version, try using dairy-free cream cheese and cheese substitutes, as well as a dairy-free milk option like almond or oat milk. Be sure to use a dairy-free soup base or homemade sauce to keep it creamy.
