Creamy Chicken and Mushroom Rigatoni Recipe for Weeknights

I crave a warm, comforting pasta bake on busy nights—but I don’t always have time for a complicated sauce. This creamy chicken mushroom rigatoni is the solution: simple to assemble, full of flavor, and it looks like you spent way more time in the kitchen than you actually did.

Everything comes together in one bowl before it goes into the oven, which makes cleanup quick. The result is rich and creamy in the center with golden, slightly crispy edges that everyone fights over.

You can bake this in a conventional oven or finish it in a pizza oven if you prefer. Using leftover roasted or rotisserie chicken saves time and makes this a perfect weeknight meal. If you have leftover brined roasted chicken, it elevates the dish even more.

Why This Chicken Mushroom Pasta Bake Works

Roasting the mushrooms and onions concentrates their savory, caramelized flavor—an easy trick to deepen the dish without extra fuss. The combination of ricotta, gruyère, and fontina creates a velvety sauce that clings to every piece of pasta for a satisfying, creamy bite.

A store-bought rotisserie chicken keeps the recipe weeknight-friendly, while leftover roasted or grilled chicken adds an extra layer of smoky, concentrated flavor when available.

About the Ingredients

A mix of baby bella and shiitake mushrooms delivers earthy depth and a meaty texture that pairs beautifully with shredded cheeses. Sun-dried tomatoes provide bright, tangy pops to balance the richness. If you prefer, oven-roasted fresh tomatoes work wonderfully and melt into the sauce for extra depth.

Fresh spinach adds color and lightness, wilting into the pasta during baking so the dish doesn’t feel overly heavy.

Tips for the Best Easy Chicken Pasta

• Reserve at least two cups of pasta water before draining. That starchy water helps loosen and silk the sauce so it finishes creamy in the oven.
• When budget allows, choose higher-quality heritage-breed or pasture-raised chicken for more flavor and better texture—it’s a small upgrade that makes a noticeable difference.
• Finish with extra grated pecorino for a sharp, salty flourish—perfect for date-night comfort.
• To make this vegetarian, omit the chicken and increase the mushrooms for a hearty, meat-free version.

Best Pasta Shapes for a Creamy Chicken Pasta

Rigatoni is ideal because the wide tubes and ridges hold sauce both inside and out, and the edges crisp nicely in the oven. If you need a substitute, penne, ziti, or medium shells will work well; avoid long strands like spaghetti or fettuccine, which tend to clump during baking.

FAQs

• Can I use rotisserie chicken? Yes—rotisserie or leftover roasted/grilled chicken is an excellent time-saver and adds great flavor.
• Can I change the mushrooms? Absolutely. Cremini, oyster, or mixed wild mushrooms are great alternatives. Use fresh mushrooms and roast them for best flavor.
• Can I make this ahead? Yes. Assemble and refrigerate for up to one day. If baking from chilled, add about 10 minutes to the bake time.
• Do I have to bake it? Baking gives the dish its signature crisp edges and melds the flavors. You can skip baking, but the texture and finish will differ.

How To Make Creamy Chicken Mushroom Rigatoni

Serves: 6 | Prep Time: 5 minutes | Cook Time: 45 minutes

Ingredients

Mushrooms
10 oz baby bella mushrooms, quartered
10 oz shiitake mushrooms, sliced
½ medium sweet onion, julienned
4 cloves garlic, minced
⅓ cup olive oil
2 tsp kosher salt (Diamond Crystal)
1 tsp black pepper
1 tsp garlic powder
1 tbsp fresh rosemary, chopped
2 tbsp fresh thyme leaves

Pasta
1 lb rigatoni pasta
2 cups ricotta cheese
1 cup gruyère, shredded
1 cup fontina, shredded
1 cup heavy cream
2 cups reserved pasta water
2 cups roasted chicken, diced
1 cup sun-dried tomatoes, chopped
1 tsp red pepper flakes
3 cups fresh spinach, chopped (packed)
¾ cup pecorino, grated

Step 1: Preheat the oven to 425°F.

Step 2: In a large bowl, combine mushrooms and onions. Drizzle with olive oil and season with salt, pepper, garlic powder, rosemary, and thyme. Toss until evenly coated.

Step 3: Spread the mushrooms and onions on a parchment-lined baking sheet and roast about 15 minutes, until nicely browned at the edges.

Step 4: While the vegetables roast, cook the rigatoni just short of al dente so it holds up during baking. Reserve two cups of pasta water before draining.

Step 5: In a large bowl, combine the par-cooked pasta with ricotta, gruyère, fontina, heavy cream, reserved pasta water, diced chicken, sun-dried tomatoes, red pepper flakes, and chopped spinach. Stir until the mixture looks creamy and the spinach begins to soften.

Step 6: Fold in the roasted mushrooms and onions, then transfer everything into a large oven-safe baking dish.

Step 7: Cover with foil and bake 20–25 minutes. Remove the foil, sprinkle with pecorino, and return to the oven for another five minutes, or until the cheese melts and the pasta edges start to brown.

Step 8: Let the pasta rest for a few minutes before serving to allow the sauce to set slightly. Serve hot and enjoy.
