This filling chicken Alfredo bake turns a favorite creamy pasta into a cozy family casserole that'll feed plenty of folks. We've skipped the heavy stuff and used smarter options so you'll get all that yummy Alfredo taste without so many calories.
I came up with this dish during a super hectic week when I needed something that would last through multiple dinners. My family went crazy for how smooth and tasty it was, and now they ask for it at least twice every month as part of our usual meals.
Ingredients
- Whole wheat pasta: Gives you more fiber and good stuff than white pasta but still keeps that awesome baking texture
- Fresh garlic: Brings in key flavor that you just can't get from the powdered kind
- Milk and chicken broth: Work together as our sauce base so we don't need heavy cream
- Greek yogurt: Makes everything creamy with a nice tang plus adds extra protein
- Freshly grated Parmesan cheese: Don't even think about skipping this for proper melting and taste
- Shredded chicken: Turns this into a full meal with lots of protein
- Provolone or mozzarella cheese: Creates that tempting melty layer on top
Step-by-Step Instructions
- Prepare the pasta:
- Get your pasta cooked just until al dente by following what the box says. This really matters because it'll keep cooking in the oven, and nobody wants mushy pasta. After you drain it, put it back in the pot to save washing another dish.
- Create the roux:
- Melt some butter in a wide pan over medium heat, then mix in flour and stir non-stop for one minute. This helps your sauce get thick without tasting like raw flour. Toss in chopped garlic and cook for half a minute until it smells good but doesn't brown.
- Build the sauce:
- Turn the heat down and pour in milk and chicken broth super slowly while whisking all the time to keep lumps away. This slow adding really helps make a smooth sauce. Put in all your seasonings and let it bubble gently, stirring often until it gets thicker, about 8-10 minutes. You'll know it's ready when the sauce sticks to the back of your spoon.
- Enrich the sauce:
- Take it off the heat and mix in the Parmesan until it melts away. Let it cool down a bit for a minute before adding the Greek yogurt. This cooling step keeps the yogurt from getting lumpy and makes your sauce nice and smooth.
- Assemble the casserole:
- Mix the chicken and sauce with your cooked pasta, making sure every bit gets covered. Put half in your baking dish, sprinkle half the cheese on top, add the rest of the pasta, then finish with the remaining cheese for a perfect melty top.
- Bake to perfection:
- Cook at 375°F for 15-20 minutes till it's hot and bubbly with golden cheese on top. Wait 5 minutes before dishing it out so the sauce can set up a bit and won't run all over your plate.

Greek yogurt is my hidden trick in this dish. I found it by chance when I ran out of heavy cream one night and needed something else. Not only does it boost the protein, but it adds this nice tang that cuts through the richness just right.
Smart Pasta Choices
The type of pasta you pick really does matter for this bake. Shapes that have little grooves or holes like cavatappi, ziti, or fusilli will grab more sauce in every bite. They also make tiny spaces where cheese can melt into, so you get flavor with every fork. Don't use long pasta like spaghetti or linguine, as they don't work as well when baked.
Make Ahead Tips
This chicken Alfredo bake works great for busy nights because you can do it in parts. Cook and pull apart your chicken up to 3 days before and keep it in the fridge. You can also put the whole thing together a day ahead, wrap it tight with foil, and stick it in the fridge. When you want to cook it, just let it sit out for 30 minutes first, then add about 10 extra minutes in the oven since it'll be cold to start.
Customization Options
This dish is super flexible based on what you've got handy. Throw in veggies like cooked mushrooms, broccoli, or spinach for some extra healthy stuff. If you want seafood instead, swap out chicken for cooked shrimp - just add them right before baking so they don't get tough. For fancy dinners, you can use half milk and half cream or swap the Greek yogurt for cream cheese to make it even richer.

Serving Suggestions
This Alfredo bake goes really well with a basic side salad with lemon dressing to balance out the richness. For a full dinner, serve it with roasted veggies like asparagus or Brussels sprouts. Garlic bread always works great for soaking up extra sauce, though the dish is filling enough on its own. If you want wine with it, try a light Pinot Grigio or Chardonnay that hasn't been in oak barrels to match the smooth flavors.
