How to Make Cheesy Chicken and Spinach Pasta Bake Recipe
Step 1: Prepare Your Oven and Baking Dish
Start by preheating your oven to 375ºF. While it warms up, generously spray a 9×9-inch pan with cooking spray to prevent sticking later—this simple step makes cleanup a breeze and keeps your pasta bake looking perfect.
Step 2: Cook the Rigatoni
Follow the package instructions to boil your rigatoni until it’s perfectly al dente. The rigatoni’s ridges are fantastic for holding all that cheesy sauce, so don’t overcook them. Once cooked, drain well and set aside while you prepare the rest.
Step 3: Drain the Spinach
Thaw your frozen chopped spinach, then press it between layers of paper towels to remove any excess liquid. This helps prevent your bake from becoming watery and ensures each bite has the perfect texture.
Step 4: Mix All Ingredients
In a large bowl, combine the cooked rigatoni, thoroughly drained spinach, cooked chopped chicken, dried minced onion flakes, canned Italian-style diced tomatoes (with juice), softened chive-and-onion cream cheese, garlic powder, salt, pepper, and half a cup of shredded mozzarella cheese. Mixing everything evenly guarantees that every spoonful bursts with layers of flavor.
Step 5: Assemble the Pasta Bake
Spoon your delicious mixture into the prepared baking dish, smoothing it out so it’s evenly spread. Then sprinkle the remaining mozzarella cheese uniformly over the top for that golden, bubbly, cheesy crust that makes it so irresistible.
Step 6: Bake Until Bubbly
Place the dish in the oven and bake uncovered for 35 to 45 minutes. Keep an eye on it toward the end—the cheese should be melted, bubbly, and golden brown, with the filling warmed through. Once it’s out, let it rest for a few minutes before serving to let everything set.
How to Serve Cheesy Chicken and Spinach Pasta Bake Recipe

Garnishes
Sprinkle freshly chopped parsley or basil over the top for a bright, herbal note that complements the creamy richness. A light dusting of grated Parmesan cheese adds an extra punch of savory flavor and a finishing touch that looks gorgeous on the plate.
Side Dishes
This bake pairs wonderfully with light, fresh sides such as a crisp green salad with vinaigrette or roasted seasonal vegetables. Garlic bread or a simple baguette are also excellent choices to help mop up the luscious sauce left on your plate.
Creative Ways to Present
Consider serving individual portions in small ramekins for a fancy twist at a dinner party. Or layer it into a large casserole dish for family-style servings. You can also add a crunchy topping like breadcrumbs mixed with a little melted butter before baking to introduce a delightful crunch contrast.
Make Ahead and Storage
Storing Leftovers
Once cooled, cover your leftovers with a tight-fitting lid or foil and refrigerate for up to 3 days. This Cheesy Chicken and Spinach Pasta Bake Recipe reheats beautifully, so you can enjoy the deliciousness again without losing flavor or texture.
Freezing
For longer storage, freeze the baked pasta in an airtight container or freezer-safe dish for up to 2 months. It’s a fantastic meal prep option—just allow it to thaw overnight in the fridge before reheating.
Reheating
Reheat individual portions in the microwave for a quick fix or warm the whole dish in the oven at 350ºF covered with foil for 20-25 minutes. Adding a splash of water or extra shredded cheese on top before reheating helps keep it moist and melty.
FAQs
Can I use fresh spinach instead of frozen?
Absolutely! Fresh spinach will work wonderfully; just be sure to sauté or wilt it first to remove excess moisture before adding it to the bake to keep the texture just right.
What type of chicken works best for this recipe?
Cooked rotisserie chicken, grilled chicken breasts, or even leftover roast chicken are great options. Just chop it into bite-sized pieces and toss it into the mix.
Is there a substitute for chive-and-onion cream cheese?
You can use plain cream cheese and add a small amount of chopped fresh chives and a pinch of onion powder if you want to mimic that flavor. Alternatively, any flavored cream cheese you love will add a nice twist.
Can I make this recipe gluten-free?
Yes! Simply swap the rigatoni with your favorite gluten-free pasta. Make sure the canned tomatoes and other ingredients you use are gluten-free to avoid any issues.
How spicy is this dish?
This Cheesy Chicken and Spinach Pasta Bake Recipe is mild and creamy with just a hint of peppery warmth. If you like it spicier, feel free to add some crushed red pepper flakes or a dash of hot sauce.
