Alfredo sauce is one of those pantry staples that’s easy to reach for but honestly easy to underuse. Most nights it just goes straight over noodles and that’s it.
This baked chicken alfredo takes that same jar of sauce and turns it into a full, hearty casserole. Pasta, chicken, and a creamy alfredo blend get baked together under a layer of melted mozzarella until bubbly and golden.
This has become my favorite way to make a simple jarred sauce feel like a real, from scratch dinner.
Why This Recipe Works
Baking the pasta in the sauce instead of just tossing it lets everything meld together, and the pasta actually absorbs some of that creamy flavor as it bakes.
Adding chicken turns it from a side dish into a full meal, and a layer of mozzarella on top gives you that golden, bubbly finish everyone wants from a good baked pasta dish.
What You’ll Need
| Ingredient | Amount | Notes |
|---|---|---|
| Penne pasta | 12 oz | |
| Cooked chicken, shredded or diced | 2 cups | Rotisserie works great |
| Alfredo sauce | 2 jars (15 oz each) | |
| Garlic | 2 cloves, minced | |
| Mozzarella cheese | 2 cups, shredded | Divided |
| Parmesan cheese | 1/2 cup, grated | |
| Italian seasoning | 1 tsp | |
| Fresh parsley | For garnish | |
| Salt and pepper | To taste |
Tools You’ll Need
- Large pot for boiling pasta
- 9×13 baking dish
- Mixing bowl
- Colander
Pro Tips
Slightly undercook the pasta. It’ll continue cooking in the oven, so pulling it a minute or two early keeps it from turning mushy.
Doctor up the jarred sauce a little. Adding minced garlic and Italian seasoning makes a big difference in flavor without much extra effort.
Mix some cheese into the pasta, not just on top. This gives you creaminess throughout instead of just a cheesy top layer.
Cover with foil for part of the baking time. This traps steam and keeps the pasta from drying out before the cheese fully melts on top.
Let it rest for a few minutes before serving. This helps the sauce set up slightly so it doesn’t run everywhere when you serve it.
Substitutions and Variations
| Original | Swap | Why It Works |
|---|---|---|
| Penne | Rigatoni or rotini | Any short pasta shape works well here |
| Chicken | Shrimp | Cooks faster, pairs really well with alfredo |
| Jarred alfredo | Homemade alfredo | Richer flavor if you have the time |
| Plain version | Add broccoli or spinach | Adds color and nutrients |
| Mozzarella | Provolone | Sharper, slightly different melt |
Make Ahead Tips
You can assemble the entire dish up to a day ahead, cover tightly, and refrigerate. Bake straight from the fridge, adding about 10 extra minutes to the covered baking time.
This also freezes well before baking. Assemble, cover tightly, and freeze for up to 2 months, then thaw overnight before baking as directed.
Full Instructions
- Preheat your oven to 375°F and grease a 9×13 baking dish.
- Bring a large pot of salted water to a boil and cook the pasta slightly under package directions. Drain.
- In a large bowl, combine the cooked pasta, shredded chicken, alfredo sauce, garlic, half the mozzarella, parmesan, and Italian seasoning. Season with salt and pepper.
- Pour the mixture into the prepared baking dish and spread evenly.
- Sprinkle the remaining mozzarella over the top.
- Cover with foil and bake for 20 minutes.
- Remove the foil and bake for another 10-15 minutes, until the cheese is melted and bubbly.
- Let rest for 5 minutes, then garnish with fresh parsley before serving.
Nutrition Notes
A serving of this bake runs around 480-520 calories depending on your portion size and cheese amounts. It’s a good source of protein thanks to the chicken and cheese, though it’s on the richer side given the alfredo sauce, so it’s best enjoyed as a hearty main rather than an everyday light meal.
Serving Suggestions
A simple green salad with a light vinaigrette helps balance out the richness of this dish. Garlic bread on the side is always a good idea for scooping up extra sauce.
Leftovers and Storage
Store leftovers in an airtight container in the fridge for up to 4 days. Reheat in the microwave or covered in the oven at 350°F for about 15 minutes.
To freeze baked leftovers, store in a freezer safe container for up to 2 months. Thaw overnight in the fridge before reheating.
