Ingredients You’ll Need
One of the best things about this Alfredo Chicken Bake is that it requires simple, everyday ingredients that you might already have in your kitchen. Here’s what you’ll need:
For the Pasta and Chicken:
- Pasta: 12 ounces (about 3 cups) of penne pasta is ideal, but you can substitute with rotini, bowtie (farfalle), ziti, or any medium-sized pasta shape that will hold the sauce well.
- Chicken: 3 cups of diced or shredded cooked chicken. This is a perfect opportunity to use rotisserie chicken for convenience, or you can cook chicken breasts or thighs specifically for this recipe.
For the Homemade Alfredo Sauce:
- Butter: 3 tablespoons of unsalted butter forms the base of your roux.
- Garlic: 1 teaspoon of minced garlic (about 2 cloves) adds aromatic flavor to the sauce.
- All-Purpose Flour: 2 tablespoons help thicken the sauce.
- Milk: 2 cups of whole milk create a rich base (2% will work but won’t be as creamy).
- Heavy Cream: 1 cup brings that luxurious, velvety texture to the Alfredo sauce.
- Parmesan Cheese: ¾ cup freshly grated provides the classic Alfredo flavor.
- Salt and Pepper: To taste for perfectly seasoned sauce.
For Topping and Finishing:
- Mozzarella Cheese: 2 cups shredded (preferably freshly shredded for better melting).
- Parsley: 1 tablespoon chopped fresh parsley for garnish (or 1 teaspoon dried).
- Cooking Spray: For greasing the baking dish.
Ingredient Tip: For the best flavor and texture, grate your cheese fresh rather than using pre-shredded packages. Pre-shredded cheese contains anti-caking agents that can affect how it melts and the overall texture of your sauce.
Step-by-Step Instructions
Creating this delicious Alfredo Chicken Bake is simpler than you might think. Follow these straightforward steps for a dinner that will have everyone asking for seconds:
Preparation:
- Preheat your oven to 375°F (190°C).
- Lightly coat a 9×13 inch (3-quart) baking dish with cooking spray and set aside.
- Cook the pasta in salted water according to package directions until al dente (slightly firm). It will continue cooking in the oven, so don’t overcook it. Drain well when done.
Making the Alfredo Sauce:
- In a large saucepan or deep skillet, melt the butter over medium heat.
- Add the minced garlic and cook for about 30 seconds until fragrant, being careful not to brown it.
- Whisk in the flour and cook for 1 minute, stirring constantly to create a roux.
- Gradually pour in the milk and heavy cream, whisking continuously to prevent lumps from forming.
- Bring the mixture to a gentle simmer, continuing to whisk frequently, until the sauce begins to thicken (about 3-5 minutes).
- Reduce heat to low and add the Parmesan cheese and ½ cup of the shredded mozzarella. Stir until all cheese is completely melted.
- Season with salt and pepper to taste. The sauce should be creamy and smooth.
Assembling and Baking:
- In a large mixing bowl, combine the cooked pasta and diced chicken.
- Pour the prepared Alfredo sauce over the pasta and chicken mixture. Gently toss until everything is evenly coated with sauce.
- Transfer the mixture to your prepared baking dish, spreading it out evenly.
- Sprinkle the remaining 1½ cups of mozzarella cheese evenly over the top.
- Bake uncovered for 20-25 minutes, or until the casserole is bubbling around the edges and the cheese on top has melted and begun to turn golden brown.
- Remove from the oven and let stand for 5 minutes before serving (this helps the sauce set slightly).
- Garnish with chopped fresh parsley before serving for a pop of color and fresh flavor.
Recipe Variations and Substitutions
One of the best things about this Alfredo Chicken Bake is how versatile it is. Here are some delicious ways to customize it:
Protein Options:
- Shrimp Alfredo: Substitute the chicken with 1 pound of peeled, deveined shrimp (add them raw to the sauce and they’ll cook during baking).
- Italian Sausage: Brown 1 pound of Italian sausage to use instead of or alongside the chicken.
- Meatless Version: Skip the chicken and add extra vegetables for a vegetarian option.
Vegetable Add-ins:
- Broccoli: Add 2 cups of lightly steamed broccoli florets.
- Spinach: Stir in 2-3 cups of fresh spinach when combining the pasta with sauce (it will wilt during baking).
- Mushrooms: Sauté 8 ounces of sliced mushrooms and mix them in with the pasta.
- Sun-dried Tomatoes: Add ½ cup chopped sun-dried tomatoes for bright bursts of flavor.
- Roasted Red Peppers: Mix in ¾ cup of diced roasted red peppers for color and sweet pepper flavor.
Flavor Enhancements:
- Italian Herbs: Add 1-2 teaspoons of Italian seasoning to the sauce.
- Heat: Include a pinch of red pepper flakes for a subtle spicy kick.
- Bacon: Mix in ½ cup of crumbled cooked bacon for a smoky flavor.
- Cheese Blend: Try using a combination of cheeses like mozzarella, provolone, and fontina for more complex flavor.
Time-Saving Shortcuts:
- Store-bought Sauce: Use 2 jars (15 oz each) of your favorite Alfredo sauce instead of making it from scratch.
- Rotisserie Chicken: Pick up a pre-cooked rotisserie chicken from the grocery store and shred or dice it.
- Pre-cooked Pasta: Some stores sell pre-cooked pasta that just needs to be heated.
Make-Ahead and Storage Tips
This Alfredo Chicken Bake is perfect for meal prepping and storing for later enjoyment. Here’s how to make the most of it:
Make-Ahead Options:
- Assemble and Refrigerate: You can assemble the entire casserole up to 24 hours before baking. Cover tightly with plastic wrap or aluminum foil and refrigerate. When ready to bake, remove from the refrigerator 30 minutes before baking and add an extra 5-10 minutes to the baking time.
- Prep Components Separately: Cook the pasta, make the sauce, and prepare the chicken up to 2 days in advance. Store them separately in airtight containers in the refrigerator, then assemble and bake when ready.
Storage Instructions:
- Refrigerating Leftovers: Store cooled leftovers in an airtight container in the refrigerator for up to 3-4 days.
- Freezing: This casserole freezes well for up to 2 months. You can freeze it either before or after baking:
- Before Baking: Assemble the casserole in a freezer-safe dish, cover tightly with plastic wrap and aluminum foil, and freeze. Thaw overnight in the refrigerator before baking.
- After Baking: Let cool completely, portion into airtight containers, and freeze. Thaw in the refrigerator before reheating.
Reheating Guidelines:
- Refrigerated Leftovers: Reheat individual portions in the microwave for 2-3 minutes, stirring halfway through. For larger portions, cover with foil and reheat in a 350°F oven for 15-20 minutes or until heated through.
- From Frozen: Thaw overnight in the refrigerator if possible, then reheat as above. If reheating directly from frozen, cover with foil and bake at 350°F for about 30-40 minutes, then uncover and continue heating until warmed through.
Serving Suggestions
Turn your Alfredo Chicken Bake into a complete meal with these perfect accompaniments:
Side Dishes:
- Garlic Bread: The ultimate companion to any pasta dish, perfect for soaking up extra sauce.
- Simple Green Salad: A light, fresh salad with vinaigrette dressing provides a nice contrast to the rich casserole.
- Roasted Vegetables: Try asparagus, Brussels sprouts, or a medley of seasonal vegetables roasted with olive oil, salt, and pepper.
- Steamed Broccoli: A simple side that adds color and nutrition to your plate.
Beverage Pairings:
- Wine: A medium-bodied Chardonnay or Pinot Grigio pairs beautifully with the creamy sauce.
- Non-Alcoholic Options: Sparkling water with lemon or a light iced tea offers refreshing contrast.
Frequently Asked Questions
Can I make this Alfredo Chicken Bake with gluten-free pasta?
Yes! You can substitute your favorite gluten-free pasta in this recipe. Just be sure to cook it according to package directions, keeping it slightly al dente as it will continue to cook in the oven. For the sauce, use a gluten-free flour blend or cornstarch to thicken instead of all-purpose flour.
Why is my Alfredo sauce grainy or separating?
This typically happens when the sauce is heated too quickly or at too high a temperature. To avoid this, make sure to keep your heat medium to medium-low when preparing the sauce, add the dairy gradually, and stir constantly. Also, freshly grated cheese melts more smoothly than pre-packaged shredded cheese.
Can I use jarred Alfredo sauce instead of making it from scratch?
Absolutely! For a quicker version, substitute about 30 ounces (two 15-oz jars) of store-bought Alfredo sauce. You may want to enhance it with a bit of extra garlic, pepper, or Parmesan cheese for more homemade flavor.
What’s the best way to cook chicken for this recipe?
The most convenient option is using rotisserie chicken. If cooking chicken specifically for this recipe, you can: 1) Poach chicken breasts in simmering water for about 15 minutes until cooked through; 2) Bake seasoned chicken breasts at 375°F for 20-25 minutes; or 3) Use an Instant Pot or pressure cooker for quick, tender results.
Can I make this dish lighter or lower in calories?
Yes, try these modifications: Use 2% milk instead of whole milk and half-and-half instead of heavy cream. Reduce the amount of cheese by about 25% and use part-skim mozzarella. Add extra vegetables to bulk up the dish without adding many calories. Consider using whole wheat pasta for additional fiber.
