Chicken Spinach Rigatoni

Chicken Spinach Rigatoni is comfort food that feels like a warm, cozy hug on a plate. Creamy, cheesy, and loaded with tender chicken and nutrient-rich spinach, this pasta is perfect for weeknights, leftovers, or easy entertaining. The sauce is luxuriously smooth thanks to chive and onion cream cheese plus heavy cream, and the rigatoni holds every bit of sauce in its ridged tubes. You’ll find this dish straightforward to pull together and endlessly satisfying.

This recipe balances rich, creamy elements with bright tomato and a gentle kick of crushed red pepper flakes. The onions soften and sweeten, the frozen spinach adds color and nutrition, and the cheeses create that dreamy, gooey texture everyone loves. Use cooked, diced chicken from your favorite source—rotisserie, roasted, or pan-seared—so dinner comes together fast.

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

Why this recipe works

This version of Chicken Spinach Rigatoni is all about simplicity without sacrificing flavor. Rigatoni’s wide diameter and ridges trap the creamy sauce and pieces of spinach and chicken, so every bite is balanced. The chive and onion cream cheese brings subtle oniony brightness and a herbaceous note that’s more interesting than plain cream cheese. Heavy cream rounds out the sauce so it clings to pasta instead of becoming runny. Mozzarella gives you that irresistible stretch while Parmesan adds savory depth.

The method is quick: cook the pasta, build a sauce in one pan with a handful of pantry staples, fold in the chicken and spinach, then finish with melty cheese. It’s a great make-ahead recipe too—reheat gently with a splash of milk or cream to revive the sauce.

Equipment

• Large pot for boiling pasta
• Large skillet or sauté pan
• Colander
• Wooden spoon or silicone spatula
• Measuring cups and spoons

Step-by-step instructions

Follow these clear, sequential steps to make Chicken Spinach Rigatoni. The directions keep the same order as the ingredient list and maintain the amounts provided.

1. Bring a large pot of salted water to a boil. Add 8 ounces rigatoni and cook according to the package directions until al dente. Reserve about ½ cup of the pasta cooking water, then drain the rigatoni and set it aside.
2. While the pasta cooks, melt 2 tablespoons butter in a large skillet over medium heat. Once the butter is melted and shimmering, add 1 cup diced onion. Sauté the onion, stirring occasionally, for 4–6 minutes or until it becomes soft and translucent but not browned.
3. Reduce the heat to medium-low and add 1 (7.5-ounce) container chive onion cream cheese to the skillet with the softened onion. Stir the cream cheese into the onion until it begins to melt and combines into a smooth mixture.
4. Pour ¾ cup heavy cream into the skillet. Stir to combine the cream with the melted cream cheese and onions, creating a silky sauce. If the sauce seems too thick, add a tablespoon or two of the reserved pasta cooking water to loosen it slightly.
5. Season the sauce with ½ teaspoon salt, ½ teaspoon pepper, and ¼ teaspoon crushed red pepper flakes. Taste and adjust the seasoning if needed. The crushed red pepper flakes add a subtle warmth—use a little less if you prefer milder heat.
6. Add 1 (14.5-ounce) can diced tomatoes, drained, to the skillet. Stir them into the sauce so their acidity brightens the creamy base. Heat for 1–2 minutes so the tomatoes warm through but still hold their shape.
7. Fold in 10 ounces frozen chopped spinach that has been thawed and squeezed dry. Stir the spinach into the sauce until it is evenly distributed and heated through. Make sure any excess moisture is squeezed out of the spinach before adding to avoid thinning the sauce.
8. Stir in 3 cups diced cooked chicken. Mix gently so the chicken is coated with the sauce and heated through. If the sauce is too thick to easily coat the pasta, add a bit of the reserved pasta cooking water, one tablespoon at a time, until you reach the desired consistency.
9. Add the drained rigatoni to the skillet and toss everything together so the pasta is fully coated in the sauce. Heat for 1–2 minutes, stirring, so the rigatoni absorbs some of the sauce and becomes well integrated with the chicken and spinach.
10. Sprinkle 2 cups shredded mozzarella cheese evenly over the pasta in the skillet. Reduce the heat to low, cover the pan, and let the cheese melt for 2–3 minutes. Alternatively, if you prefer a browned top, transfer the skillet to a preheated broiler-safe dish, sprinkle the mozzarella, and place under the broiler for 1–3 minutes until the cheese is bubbly and lightly golden. Watch closely to prevent burning.
11. Finish by sprinkling ½ cup freshly shredded Parmesan cheese over the melted mozzarella. Give the pasta a gentle toss to incorporate some of the Parmesan, or leave it on top as a flavorful garnish. Serve immediately while hot.

Troubleshooting and tips

• If the sauce becomes too thick while you’re finishing, stir in small amounts of the reserved pasta water until it loosens to your liking. The starchy water helps the sauce cling to the rigatoni.
• For a lighter version, you can reduce the heavy cream slightly and substitute part with milk, but the texture will be less decadent.
• Make sure to squeeze as much liquid as possible out of the thawed spinach; otherwise the sauce can become watery and lose its creaminess.
• Leftovers store well in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stove over low heat with a splash of cream or milk to restore creaminess.
• To add brightness, finish with a squeeze of lemon or a handful of chopped fresh herbs such as basil or parsley right before serving.

Serving suggestions

This chicken and spinach rigatoni pairs beautifully with a simple green salad and a tangy vinaigrette to cut through the richness. Garlic bread or a crusty baguette is perfect for sopping up any extra sauce. For a complete weeknight meal, serve with steamed vegetables or roasted asparagus.

Make-ahead and variations

To make this recipe ahead, prepare the sauce and pasta up to the point of adding the mozzarella and Parmesan. Cool, cover, and refrigerate separately from the cheese for up to 2 days. When ready to serve, reheat the pasta and sauce together on the stove over medium-low heat, add the cheeses, and melt as directed.

Variations to try:
– Swap the rigatoni for penne or ziti if that’s what you have on hand.
– Stir in a handful of sun-dried tomatoes for a deeper, slightly sweet tomato note.
– Add sliced mushrooms when you sauté the onions for an earthy twist.
– Stir in a cup of cooked peas for extra color and sweetness.

Notes on protein and cheese

Using cooked, diced chicken keeps this recipe fast—leftover roasted chicken, rotisserie chicken, or quickly pan-seared breasts all work well. For best melt and texture, shred or dice the chicken uniformly so it warms evenly in the sauce.

Freshly shredding your mozzarella and Parmesan delivers the best texture and flavor. Pre-shredded cheeses often contain anti-caking agents that can slightly affect melting behavior.

Nutrition snapshot (approximate per serving)

Per serving, this dish provides a comforting balance of protein, carbohydrates, and fats. Exact nutrition depends on specific brands and portion sizes, but expect a generous protein portion from the chicken and cheeses, carbohydrates from the rigatoni, and calories from the cream and cheeses.
