Creamy Chicken Pasta Bake is my answer to those nights when I want something rich and homemade but don’t have the energy for a complicated dinner. It combines a creamy tomato sauce, browned bits of chicken, and mushrooms with rigatoni, all finished under a layer of melted mozzarella and Parmesan.
Real talk: the sauce is what makes this one worth the extra few minutes. It’s not a thin tomato sauce and it’s not a heavy cream sauce either, it’s somewhere in between, and that balance is exactly why my daughters ask for seconds every time I make it. If your family loves rich, cheesy chicken dinners like our Creamy Garlic Tuscan Chicken, this pasta bake belongs on your list next.
Dad always said a good sauce needs time to build layers, and that’s exactly what happens here as the tomato paste, stock, and cream come together in stages.
Why You’ll Love This Creamy Chicken Pasta Bake
This dish gives you a proper saucy pasta bake, not a dry one. The tomato and cream sauce coats every piece of rigatoni, and the mushrooms add an earthy depth that keeps things interesting.
It feeds a crowd generously, with enough leftovers for lunch the next day. In my kitchen, that’s basically a requirement for a weeknight dinner to earn a repeat spot.
The spinach wilts right into the sauce so you’re getting a vegetable in without anyone really noticing. And the golden, bubbling mozzarella on top makes it look like something you’d order at a restaurant.
It also reheats nicely, which matters a lot on the nights when I’m cooking once and eating twice.
Ingredients for Creamy Chicken Pasta Bake
I’ve made this enough times to know exactly which steps matter most, so let me walk you through what you’ll need.
10 ounces (300g) dry rigatoni, or other short pasta
1 tablespoon olive oil
2 tablespoons butter
1 pound (450g) chicken breast, cut into bite-size pieces
1 medium onion, finely diced
ยฝ pound (225g) mushrooms, sliced
4 garlic cloves, finely chopped
2 tablespoons tomato paste
ยฝ cup (120g) low-sodium chicken stock
2 cups (500g) tomato sauce (passata)
6-8 fresh basil leaves, roughly torn
1 cup (250g) half and half (single cream)
1 cup (100g) Parmesan, freshly grated, divided
2 cups (60g) fresh spinach, roughly torn
2 balls fresh light mozzarella, roughly torn
Salt and freshly ground black pepper to taste
I prefer chestnut mushrooms here if I can find them, since they carry more flavor than the plain white kind, but honestly whatever’s in my fridge works fine. Low-sodium chicken stock lets you control the seasoning at the end, which I find matters a lot once the Parmesan and mozzarella go in.
For the tomato sauce, look for passata or a smooth strained tomato sauce rather than a chunky marinara, it gives the sauce that silky texture. If half and half isn’t available, whole milk with a splash of heavy cream works as a substitute.
I always drain my torn mozzarella on a paper towel before it goes on top. It sounds like a small step, but it keeps the extra moisture from watering down the sauce underneath.
How to Make Creamy Chicken Pasta Bake
The key technique here is building the sauce in stages, browning the chicken first, then the vegetables, then letting the tomato paste cook down before any liquid goes in.
- Preheat the oven to 200ยฐC (400ยฐF). Tear the mozzarella and leave it on a piece of kitchen paper to drain while you make the sauce.
- Bring a large pot of water to a boil and salt it generously. Cook the rigatoni for 2 minutes less than the package instructions, then drain and set aside.
- Heat the olive oil and butter in a large, deep pan or Dutch oven over medium heat. Add the chicken, season with salt and pepper, and cook for 5 to 6 minutes until golden and cooked through. Remove the chicken and set aside.
- Add the onion and mushrooms to the same pan and cook for 6 to 7 minutes over medium heat, until the mushrooms start to color.
- Stir in the garlic and cook for another minute, then add the tomato paste and cook for 1 minute more, until it darkens slightly.
- Pour in the chicken stock and tomato sauce, add the torn basil, and simmer for 5 minutes until slightly thickened.
- Lower the heat, stir in the half and half and a third of the Parmesan, then add the spinach and cook for 1 to 2 minutes until wilted. Return the cooked chicken to the pan and season to taste.
- Add the drained rigatoni to the pan and toss until everything is well coated.
- Transfer everything to a baking dish. Scatter the torn mozzarella and remaining Parmesan evenly over the top.
- Bake uncovered for 20 to 25 minutes, until bubbling and golden at the edges. Let it rest for 5 minutes before serving.
Pro tip: take the chicken out of the pan once it’s browned and don’t add it back until the very end. Leaving it in the pot while you build the sauce dries it out. Another one, don’t worry if the sauce looks thin right before it goes in the oven, it thickens up as it bakes and the pasta absorbs the extra moisture.
Common mistake to avoid: cooking the pasta all the way through before it goes into the oven. Pull it 2 minutes early so it doesn’t turn mushy under the cheese.
What to Serve with Creamy Chicken Pasta Bake
This bake is rich enough to stand on its own as a full meal, so I like to keep the sides simple and let it be the star.
A crisp green salad with a light vinaigrette balances out the creaminess nicely. Garlic bread or a crusty loaf is perfect for mopping up any extra sauce left in the dish, which happens more often than not in my house.
Roasted broccoli, garlic roasted asparagus, or steamed green beans all work well if you want to round it out with more vegetables. Buttered corn is another easy add if you’re feeding picky eaters who want something familiar on the plate.
If you’re planning a week of hearty chicken dinners, this one pairs nicely with our Sheet Pan Chicken and Potatoes for another easy night that doesn’t sacrifice flavor.
Pro Tips & Variations
Undercook your pasta by about 2 minutes before it goes into the oven. It keeps cooking as the bake sets, and you’ll end up with perfectly tender rigatoni instead of something mushy.
Drain your torn mozzarella on a paper towel first. It’s a small step that keeps the top from getting watery once it melts.
Take the chicken out of the pan after browning and don’t return it until the very last step. It stays juicier that way.
Let the finished bake rest for 5 minutes before serving. It firms up just enough to hold together on the plate.
For variations, chicken thighs work beautifully here and stay juicier through the bake than breast meat. You can also turn this into a creamy white chicken pasta bake by skipping the tomato paste and passata and adding a bit more stock and cream instead. For some heat, stir in a pinch of red pepper flakes with the garlic. If your family enjoys a similar creamy, veggie-loaded chicken bake, our Creamy Chicken Spinach Mushroom Casserole is worth adding to your rotation too.
Storage & Reheating Tips
This one is best fresh out of the oven, but leftovers still hold up well. Store them in an airtight container in the fridge for up to 3 days.
I like reheating individual portions in the microwave in short bursts so the sauce doesn’t separate. If you’re using the oven, cover the dish with foil and reheat until piping hot.
Since there’s plenty of sauce baked into the dish, leftovers won’t dry out, though the texture is always a touch less creamy than day one. I usually add a small splash of milk when reheating to bring it back to life.
Common Questions
Can I use chicken thighs instead of chicken breast?
Yes. Boneless chicken thighs work great here and tend to stay juicier through the bake.
Can I make this without tomato sauce for a creamier version?
Absolutely. Leave out the tomato paste and passata, and increase the stock and cream slightly for a white version of this bake.
Why does my sauce look thin before baking?
That’s normal. It thickens up in the oven as the pasta absorbs some of the liquid, so don’t add extra thickener at this stage.
Can I add spice to this dish?
Yes. A pinch of red pepper flakes added with the garlic gives it a nice bit of heat without overpowering the sauce.
How long do leftovers keep?
Up to 3 days in the fridge in an airtight container. Reheat gently with a splash of milk to loosen the sauce back up.
This Creamy Chicken Pasta Bake has become one of those dinners I reach for whenever I want something that feels a little special without a long ingredient list of effort behind it. It’s rich, hearty, and the kind of meal that brings everyone to the table without any convincing needed. If you’re building out your weeknight rotation, our Million Dollar Chicken Casserole is another one worth trying next.
