Why You’ll Love This Recipe
There are plenty of chicken pasta recipes out there, but this one has a few things going for it.
It’s seriously creamy. The Alfredo sauce is made right on the stovetop with butter, garlic, flour, half & half, milk, and plenty of cheese. No sad, watery sauce here.
It feeds a crowd. This recipe makes 8 servings, which means there’s plenty to go around. Or plenty for tomorrow. I’m not judging.
It’s comfort food through and through. Tender chicken, pasta, creamy sauce, and a blanket of melted cheese. Sometimes dinner doesn’t need to be complicated.
It’s make-ahead friendly. You can assemble the casserole ahead of time and keep it in the refrigerator until you’re ready to bake.
And the leftovers? Even better when you’re standing in front of the refrigerator the next day looking for something delicious.
For the Chicken and Pasta
- Chicken Breasts – I use boneless, skinless chicken breasts here. Marinating them in Italian dressing for a few hours or overnight gives them even more flavor.
- Penne Pasta – this is perfect for this recipe because the pasta holds onto all that creamy Alfredo sauce.
- Vegetable Oil – for cooking the chicken.
- Thyme – just a little adds a subtle earthy flavor to the chicken.
- Poultry Seasoning – this gives the chicken an extra boost of savory flavor.
- Salt and Pepper – for seasoning the chicken and bringing all those flavors together.
For the Alfredo Sauce
- Olive Oil – this helps build the base of the sauce and adds a little richness.
- Butter – because Alfredo sauce needs butter. It gives the sauce that rich, silky flavor.
- Minced Garlic – this is where that delicious garlicky flavor comes from.
- All-Purpose Flour – this helps thicken the sauce so it coats the pasta beautifully.
- Half & Half – this is what makes the Alfredo sauce rich and creamy without using only heavy cream.
- Milk – helps balance out the richness while keeping the sauce nice and creamy.
- Italian Five-Cheese Blend – this melts into the sauce and gives it that extra-cheesy flavor. And yes, there’s more cheese coming!
For Assembly and Baking
- Italian Five-Cheese Blend – the rest of the cheese goes right on top of the casserole, where it melts into a bubbly, golden layer.
- Italian Seasoning – for a little extra Italian flavor and a pretty finish.
- Non-Stick Spray – for lightly greasing the baking dish so the cheesy pasta doesn’t stick.
Step-by-Step Instructions
Prepare the Chicken & Pasta
First, let’s get the chicken going.
If you have the time, marinate the chicken in Italian dressing for a few hours or overnight. It’s an extra step, sure, but it gives the chicken another layer of flavor.
While that’s happening—or while you’re pretending you planned ahead—cook the penne according to the package directions. Drain it and set it aside.
Heat the vegetable oil in a skillet over medium heat.
Now slice the chicken breasts in half lengthwise. This helps them cook evenly and keeps the thicker parts from taking forever to catch up with the thinner ones.
Season the chicken with salt, pepper, thyme, and poultry seasoning, then cook it until it’s completely cooked through. Let it cool for a bit, then cut it into bite-sized pieces.
Easy enough.
Make the Alfredo Sauce
Now for the good stuff.
Preheat the oven to 350°F (175°C).
Melt the butter in a large skillet over medium heat, then add the minced garlic. Give it a minute or two to get fragrant.
And when that garlic starts smelling good?
You’re on the right track.
Whisk in the flour and cook until bubbly. Then gradually whisk in the half & half and milk.
Bring everything to a gentle boil, then lower the heat and let it simmer for 5 minutes.
Now comes the cheese.
Stir in 1½ cups of the shredded Italian five-cheese blend and let the sauce cook for another 5 minutes, until it thickens.
At this point, you should have a creamy, cheesy Alfredo sauce that you could very easily eat with a spoon.
But don’t.
We have a casserole to make.
Assemble & Bake
Grab a large bowl and combine the cooked pasta, chicken, and Alfredo sauce.
Give everything a good mix so that the pasta gets coated in all that creamy goodness.
Lightly grease a 9×13-inch baking dish and pour the mixture inside.
Then comes my favorite part.
Sprinkle the remaining cheese all over the top. Add the Italian seasoning and a little pepper, then pop the whole thing into the oven.
Bake for 30 minutes, or until it’s bubbly and golden brown.
And now comes the hard part.
Waiting.
Expert Tips
Marinate the chicken if you can. A few hours in Italian dressing—or overnight—adds extra flavor without making the recipe much more complicated.
Slice the chicken evenly. Cutting the breasts in half lengthwise helps them cook more evenly, so you don’t end up with one part perfectly cooked and another part still waiting around.
Don’t walk away from the Alfredo sauce. Once the milk and half & half are in the skillet, keep an eye on it and stir as needed while it simmers.
Let the sauce thicken. The sauce should have some body before you mix it with the pasta. That creamy consistency is what helps the finished casserole hold together.
Give the cheese some room to shine. The cheese on top isn’t just decoration. It melts into that bubbly, golden layer that makes a baked pasta casserole so irresistible.
Let it cool slightly before serving. I know. You just pulled a bubbling pan of cheesy Alfredo pasta from the oven and everyone is hungry. But giving it a few minutes to settle makes serving much easier.
Recipe Variations
Make It With Rotisserie Chicken
In a hurry?
Use cooked rotisserie chicken instead of cooking the chicken breasts from scratch. It’s one of those little shortcuts that can save dinner when the day has gotten away from you.
Add Some Vegetables
Broccoli, spinach, and mushrooms all work beautifully with creamy Alfredo sauce.
Just cook or blanch the vegetables first so they’re tender when they go into the casserole.
Try Chicken Thighs
Chicken breasts are what this recipe calls for, but boneless chicken thighs are another good option if you prefer darker meat.
They’re juicy, flavorful, and very forgiving.
Change the Pasta
Penne is a great choice because all those little ridges and hollow centers grab onto the Alfredo sauce.
But if penne isn’t what you have in the pantry, rotini, rigatoni, or macaroni can work, too.
Storage & Reheating
Got leftovers?
Lucky you.
Store the cooled Chicken Alfredo Bake in an airtight container, or cover the baking dish tightly, and refrigerate for up to 3–4 days.
For individual portions, reheat in the microwave until hot throughout. Covering the portion loosely while reheating can help keep the pasta from drying out.
If you’re reheating a larger amount, cover the casserole and warm it in a 350°F oven until heated through.
Can You Freeze Chicken Alfredo Bake?
Absolutely.
For the best results, assemble the casserole but don’t bake it. Wrap it tightly in plastic wrap and then aluminum foil before placing it in the freezer.
When you’re ready to bake it, thaw it overnight in the refrigerator and follow the original recipe instructions.
Serving Suggestions
This is one of those casseroles that doesn’t need much help.
It’s already got chicken, pasta, creamy Alfredo sauce, and enough cheese to make everyone at the table happy.
But if you want to round things out, serve it with a crisp green salad for something fresh alongside all that creamy goodness.
Garlic bread is another obvious choice. You’ll want something to mop up every last bit of Alfredo sauce, after all.
For a vegetable side, try broccoli, green beans, or asparagus. Something simple is perfect here.
And if you’re serving this for a family gathering or a cozy Sunday dinner, put the casserole right in the middle of the table and let everyone help themselves.
Just be warned.
