Why you’ll love this Chicken Spinach Rigatoni

This recipe balances creamy richness and fresh, savory notes. The chive and onion cream cheese blends with heavy cream to create a silky sauce that clings to rigatoni’s ridges, while drained canned diced tomatoes add a bright pop. Frozen chopped spinach is an easy, nutrient-packed shortcut, and cooked diced chicken makes this a complete meal in one dish. Top it all with shredded mozzarella and freshly shredded Parmesan for gooey, golden goodness.

Ingredients

• 8 ounces Rigatoni
• 2 tablespoons butter
• 1 cup diced onion
• 1 (7.5-ounce) container chive onion cream cheese
• ¾ cup heavy cream
• ½ teaspoon salt
• ½ teaspoon pepper
• ¼ teaspoon crushed red pepper flakes
• 1 (14.5-ounce) can diced tomatoes, drained
• 10 ounces frozen chopped spinach, thawed and squeezed dry
• 3 cups diced cooked chicken
• 2 cups shredded mozzarella cheese
• ½ cup freshly shredded Parmesan cheese

Make-ahead and substitutions

Prep the spinach, dice the cooked chicken, and shred the cheeses ahead of time to make weeknight assembly a breeze. If you prefer a lighter texture, swap half-and-half for the heavy cream, but the sauce will be slightly less silky. If you don’t have a chive onion cream cheese container, try using a plain cream cheese mixed with 1 teaspoon dried chives and a pinch of onion powder to mimic the flavor.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• 9×13-inch baking dish (or similar)
• Mixing spoon and spatula
• Colander

Step-by-step directions

Follow these clear steps in order to create a comforting pan of Chicken Spinach Rigatoni with minimal fuss. The directions have been rewritten to be straightforward and easy to follow while keeping the ingredient amounts exactly as listed above.

1. Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish or a similarly sized casserole dish and set it aside while you prepare the pasta and sauce.
2. Bring a large pot of salted water to a rolling boil. Add 8 ounces rigatoni and cook according to package directions until the pasta is just al dente. Stir occasionally to prevent sticking. Once done, reserve about ½ cup of the pasta cooking water, then drain the rigatoni in a colander and set it aside.
3. While the pasta cooks, melt 2 tablespoons butter in a large skillet over medium heat. Add 1 cup diced onion and sauté, stirring occasionally, until the onion becomes soft and translucent, about 4 to 6 minutes. Do not let the onion brown; keep the heat moderate so it sweats and sweetens.
4. Reduce the heat to low and add the 1 (7.5-ounce) container chive onion cream cheese to the pan with the softened onion. Stir constantly until the cream cheese melts and combines with the onions to form a smooth base.
5. Pour in ¾ cup heavy cream and stir until the mixture becomes a homogenous, creamy sauce. If the sauce seems too thick, add a few tablespoons of the reserved pasta cooking water to reach a slightly thinner consistency that will coat the rigatoni well.
6. Season the sauce with ½ teaspoon salt, ½ teaspoon pepper, and ¼ teaspoon crushed red pepper flakes. Taste and adjust the seasoning as you prefer. The crushed red pepper adds just a hint of heat; omit it if you want a milder bite.
7. Fold in the drained contents of 1 (14.5-ounce) can diced tomatoes and 10 ounces frozen chopped spinach that has been thawed and squeezed dry. Stir gently until the tomatoes and spinach are evenly distributed throughout the cream sauce. Maintain a gentle heat so the mixture heats through without boiling vigorously.
8. Add 3 cups diced cooked chicken to the sauce and stir to combine. Ensure the chicken pieces are warmed through and evenly coated with the creamy mixture. If the sauce has thickened too much, stir in a little of the reserved pasta water until you reach the desired sauciness.
9. Remove the skillet from the heat and add the drained rigatoni to the sauce. Gently toss until every piece of rigatoni is coated in the creamy tomato-spinach mixture and the chicken is evenly distributed. Transfer the pasta mixture into the prepared baking dish, spreading it into an even layer.
10. Sprinkle 2 cups shredded mozzarella cheese evenly over the top of the pasta. Finish with ½ cup freshly shredded Parmesan cheese for a savory, slightly nutty crust.
11. Bake the dish in the preheated 350°F oven until the cheese is melted and the top is bubbly and starting to turn golden, about 20 to 25 minutes. If you like a crispier top, place the baking dish under the broiler for 1 to 2 minutes, watching closely so the cheese doesn’t burn.
12. Remove the Chicken Spinach Rigatoni from the oven and let it rest for 5 to 10 minutes. This short rest helps the sauce thicken slightly and makes the casserole easier to serve. Serve warm, portioned onto plates or in bowls, and enjoy the balance of creamy sauce, tender pasta, and melty cheese.

Serving suggestions

Pair this Chicken Spinach Rigatoni with a simple green salad dressed in lemon vinaigrette to cut through the richness, or serve it alongside crusty bread to sop up any leftover sauce. A light, crisp white wine or an iced tea complements the creamy flavors nicely.

Storage and reheating

Refrigerate leftovers in an airtight container for up to 3 days. To reheat, place a portion in a microwave-safe dish and heat in 30-second intervals, stirring between intervals, until warmed through. For a crisp top, reheat in a 350°F oven for 10–15 minutes covered with foil, then remove the foil for the last few minutes to refresh the cheese topping.

Tips for success

• Do not overcook the rigatoni in the boiling water; aim for just al dente since it will finish baking in the oven.
• Be sure to squeeze the thawed spinach dry. Excess moisture from spinach can make the sauce thin and watery.
• If you prefer smaller chicken bites, chop the cooked chicken into smaller pieces so each forkful gets a bit of protein.
• Reserve a small amount of pasta cooking water. Its starchiness helps loosen and bind the sauce when needed.
• Use freshly shredded Parmesan for better melting and flavor compared with pre-grated versions.
