Ingredients & Equipment: Everything You’ll Need

Most of these ingredients are pantry staples, making this a truly convenient meal.

For the Creamy Alfredo Sauce & Pasta

• 1 lb Pasta (Fettuccine, Penne, or Rigatoni work great)
• 1/2 cup Unsalted Butter
• 2 cloves Garlic, minced
• 1 ½ cups Heavy Cream
• 1 cup Grated Parmesan Cheese (freshly grated is best!)
• 1/4 tsp Black Pepper
• Pinch of Nutmeg (optional, but a classic Alfredo touch!)
• Salt, to taste
• For the Chicken & Cheesy Topping
• 2 cups Cooked Leftover Chicken, shredded or diced
• 1 cup Shredded Mozzarella Cheese (or Italian blend)
• 1/4 cup Grated Parmesan Cheese (for topping)
• 2 Tbsp Fresh Parsley, chopped (for garnish)
• Essential Equipment
• A large pot for cooking pasta.
• A large skillet or saucepan for making the Alfredo sauce.
• A 9×13 inch baking dish (or similar 3-quart oven-safe dish). A ceramic baking dish is perfect for even cooking and serving right to the table. I’ve had great success with this classic Pyrex baking dish from Amazon for all my casseroles and bakes.

Your “Baby Steps” Guide to This Delicious Pasta Bake

We’ll break this down into easy-to-follow steps, ensuring a creamy, cheesy success!

Step 1: Cook the Pasta

1. Boil Water: Fill your large pot with water and bring it to a rolling boil over high heat. Add a generous pinch of salt (this flavors the pasta!).
2. Cook Pasta: Add your pasta to the boiling water. Cook according to package directions until it is al dente (cooked but still firm to the bite). You don’t want it mushy, as it will cook a little more in the oven.
3. Drain & Set Aside: Once cooked, drain the pasta thoroughly. You don’t need to rinse it. Set it aside.

Step 2: Make the Simple Alfredo Sauce

This sauce is surprisingly easy and comes together quickly.

1. Melt Butter: Place your large skillet or saucepan over medium heat. Add the 1/2 cup of butter and let it melt completely.
2. Sauté Garlic: Add the minced garlic to the melted butter. Cook for just 1 minute, stirring constantly, until it’s fragrant. Be careful not to let the garlic brown or burn.
3. Add Cream: Slowly pour in the 1 ½ cups of heavy cream. Stir gently and bring the mixture to a very gentle simmer. Do not let it boil rapidly.
4. Whisk in Parmesan: Reduce the heat to low. Add the 1 cup of grated Parmesan cheese, the black pepper, and the pinch of nutmeg (if using). Whisk constantly until the cheese has melted and the sauce is smooth and slightly thickened.
5. Taste and Adjust: Taste the sauce. Add salt as needed, keeping in mind that the Parmesan cheese is already salty.

Step 3: Combine and Assemble the Bake

1. Preheat Oven: While you’re making the sauce, preheat your oven to 375°F (190°C).
2. Grease Dish: Lightly grease your 9×13 inch baking dish with a little butter or cooking spray.
3. Combine Filling: In the large skillet with the Alfredo sauce (or a separate large mixing bowl if your skillet isn’t big enough), add the drained pasta and the 2 cups of shredded or diced cooked chicken.
4. Stir Gently: Stir everything gently until the pasta and chicken are evenly coated in the creamy Alfredo sauce.
5. Transfer to Dish: Pour the entire pasta and chicken mixture into your prepared baking dish. Spread it out evenly.

Step 4: Top and Bake to Golden Perfection

1. Add Cheese Topping: Sprinkle the 1 cup of shredded mozzarella cheese evenly over the top of the pasta mixture. Then, sprinkle the additional 1/4 cup of grated Parmesan cheese over the mozzarella.
2. Cover (Optional): If you find your cheese browns too quickly, you can loosely cover the dish with aluminum foil for the first 10-15 minutes of baking, then remove it for the last part.
3. Bake: Place the baking dish in your preheated oven. Bake for 20-25 minutes, or until the top is golden brown and bubbly, and the sauce is hot and simmering around the edges.
4. Rest and Garnish: Carefully remove the dish from the oven. Let it rest for 5-10 minutes before serving. This helps the sauce set slightly. Garnish with fresh chopped parsley just before serving.

Pro Tips for the Best Chicken Alfredo Pasta Bake

• Freshly Grated Parmesan Makes a Difference: Pre-grated Parmesan often contains anti-caking agents that can make your sauce gritty. Freshly grated melts smoothly and tastes much better.
• Don’t Overcook the Pasta: Remember, it cooks a little more in the oven. Undercooking it slightly ensures it doesn’t turn mushy.
• Add Veggies: Want to sneak in some greens? Stir in a cup of steamed broccoli florets or spinach (stirred in at the very end with the chicken) for extra nutrition.

Frequently Asked Questions (FAQ)

Can I make the Alfredo sauce ahead of time?

Yes, you can! You can make the Alfredo sauce up to 2 days in advance and store it in an airtight container in the refrigerator. Gently reheat it on the stove over low heat, stirring occasionally, before combining with the pasta and chicken.

What kind of leftover chicken works best?

Any cooked chicken works perfectly! Rotisserie chicken is ideal for its flavor and tenderness. Leftover roasted chicken, grilled chicken, or even boiled chicken breasts (shredded) are all excellent choices.

Can I freeze this pasta bake?

Yes, you can! Assemble the pasta bake (but do not bake it). Cover it tightly with aluminum foil (you might want two layers) and freeze for up to 2-3 months. To bake from frozen, remove the foil, cover lightly with new foil, and bake at 375°F for about 45-60 minutes, then remove the foil and bake for an additional 15-20 minutes, or until bubbly and golden. For general freezing tips, a reliable source like FoodSafety.gov offers excellent guidelines for safe food storage.
