This hearty chicken Alfredo bake transforms the classic creamy pasta dish into a comforting casserole perfect for serving a crowd. By skipping the heavy cream and using smarter ingredients, you'll enjoy all the flavor of traditional Alfredo with fewer calories.
I discovered this recipe during a particularly busy week when I needed something that would stretch over several dinners. My family was so impressed with the creamy texture and rich flavor that it's now requested at least twice a month in our regular rotation.
Ingredients
- Whole wheat pasta: Provides more fiber and nutrients than regular pasta while maintaining that perfect texture for baking
- Fresh garlic: Delivers essential flavor that powder simply cannot match
- Milk and chicken broth: Create the base for our sauce without relying on heavy cream
- Greek yogurt: Adds creaminess and tanginess while boosting protein content
- Freshly grated Parmesan cheese: Absolutely non-negotiable for proper melting and flavor
- Shredded chicken: Makes this a complete meal with plenty of protein
- Provolone or mozzarella cheese: Creates that irresistible melty top layer
Step-by-Step Instructions
- Prepare the pasta:
- Cook your pasta just to al dente following the package directions. This is crucial because the pasta will continue cooking in the oven, and you want to avoid a mushy final dish. After draining well, return it to the pot to save dishes later.
- Create the roux:
- Melt butter in a wide sauté pan over medium heat, then add flour and cook for exactly one minute while stirring constantly. This creates the thickening base for your sauce without developing a raw flour taste. Add minced garlic and cook just 30 seconds until fragrant but not browned.
- Build the sauce:
- Reduce heat to low and very slowly pour in milk and chicken broth while whisking continuously to prevent lumps. This gradual addition is key to a smooth sauce. Add all seasonings and bring to a gentle simmer, stirring frequently until the sauce reduces and thickens, about 8 to 10 minutes. The sauce should coat the back of a spoon.
- Enrich the sauce:
- Remove from heat and stir in Parmesan cheese until melted. Allow to cool slightly for one minute before incorporating Greek yogurt. This cooling step prevents the yogurt from curdling and ensures a silky smooth sauce.
- Assemble the casserole:
- Combine the chicken and sauce with the cooked pasta, stirring thoroughly to coat every piece. Layer half the mixture in your baking dish, sprinkle with half the cheese, add remaining pasta, then top with remaining cheeses for the perfect melty finish.
- Bake to perfection:
- Bake at 375°F for 15 to 20 minutes until hot and bubbly with a golden cheese top. Let rest 5 minutes before serving to allow the sauce to set slightly for easier serving.

The Greek yogurt is my secret weapon in this recipe. I discovered it by accident when I ran out of heavy cream one night and needed a substitution. Not only does it add protein, but it gives the sauce a subtle tanginess that balances the richness perfectly.
Perfect Pasta Selection
The shape of pasta you choose actually matters significantly for this dish. Shapes with ridges or hollows like cavatappi, ziti, or fusilli will hold more sauce in each bite. Their structure also creates little pockets where cheese can melt into, ensuring flavor in every forkful. Avoid long pasta like spaghetti or linguine, as they don't stand up as well in a baked dish.
Make Ahead Tips
This chicken Alfredo bake is perfect for busy weeknights because you can prepare it in stages. Cook and shred chicken up to 3 days ahead and store in the refrigerator. You can also assemble the entire casserole a day before, cover tightly with foil, and refrigerate. When ready to bake, simply let it sit at room temperature for 30 minutes before placing in the oven, and add about 10 minutes to the baking time since it will be starting cold.
Customization Options
This recipe welcomes customization based on what you have available. Add vegetables like sautéed mushrooms, steamed broccoli, or wilted spinach for extra nutrition. For a seafood variation, replace the chicken with cooked shrimp added just before baking to prevent overcooking. If you prefer a more indulgent version for special occasions, substitute half the milk with half and half or replace the Greek yogurt with cream cheese for an even richer consistency.

Serving Suggestions
This Alfredo bake pairs beautifully with a simple side salad dressed with lemon vinaigrette to cut through the richness. For a complete meal, serve alongside roasted vegetables like asparagus or Brussels sprouts. A slice of garlic bread is always welcome for sauce scooping, though the dish is hearty enough to stand alone. For wine pairing, choose a crisp Pinot Grigio or unoaked Chardonnay to complement the creamy flavors.
