Step-by-Step Instructions

preparing chicken alfredo pasta in frying pan

This easy family dinner is perfect for busy weeknights—no fuss, just fast comfort food. Here’s how to pull it together in just 20 minutes.

Step 1: Cook the Pasta

Start by boiling water in a large pot. Add a bit of salt and toss in your pasta. Cook it just shy of fully done—about a minute less than the package says. This helps it hold up better when baked. Once done, drain and set aside.

Step 2: Get the Oven Ready

Set your oven to 375°F (190°C) so it heats up while you prep. If you don’t have pre-cooked chicken, now’s a good time to quickly pan-fry some bite-sized chicken pieces until they’re nicely browned and cooked through.

Step 3: Mix the Creamy Base

In a large bowl, stir together the Alfredo sauce, sour cream, grated Parmesan, garlic powder, pepper, and a pinch of salt. Once smooth, fold in your shredded chicken and cooked pasta until everything is coated in the creamy mixture.

Step 4: Build the Casserole

Grease a 9x13 baking dish and spoon in the mixture evenly. Sprinkle shredded mozzarella all over the top. If you're adding extras like broccoli or mushrooms, mix them in before the cheese goes on.

Step 5: Bake and Serve

Pop the dish in the oven for about 10–12 minutes, just until the cheese melts and the casserole is heated through. For a golden, bubbly top, switch to broil mode for the last 1–2 minutes—just keep an eye on it. Finish with chopped parsley or a sprinkle of red pepper flakes for a final touch. Serve hot and enjoy!

Tips to Make It Even Faster

  • Shred up leftover or rotisserie chicken to make your cooking go faster.
  • For an easy way to eat more greens, try steaming broccoli or spinach in your microwave.
  • Mix all the ingredients ahead and refrigerate; just before dinner, bake your casserole.
  • For less work, mix all the ingredients together in the baking dish.

Variations to Try

Feeling like making something different with chicken alfredo casserole? These are a few ways you can keep the romance alive:

1. Low-Carb Version

Exchange normal pasta for zucchini noodles or cauliflower pasta so you eat fewer carbs without needing to change the flavor.

2. Cajun-Style Alfredo

To make the sauce smoky and spicier, add a teaspoon of either Cajun seasoning or paprika to the mixture.

3. Ido Herb Twist

A touch of basil, oregano and sun-dried tomatoes will make your dish more Italian.

4. Mexican Fusion

Instead of using Alfredo, try mixing sour cream, salsa and cheddar together. Including black beans and corn will give your casserole a Spanish flair.

5. Cheesy Deluxe

If you can’t have enough cheese, sneak some into your meals. Adding some cheddar or provolone under the mozzarella will make your pizza extra cheesy.

Make-Ahead and Storage Tips

Make It Ahead of Time

Want to save time later? You can put the whole casserole together a day early. Just cover it and pop it in the fridge. When you're ready to eat, bake it at 375°F for about 15–20 minutes until it’s hot and bubbly.

How to Freeze It

Need a longer prep window? Assemble the casserole (don’t bake it), then store it in a freezer-safe dish or foil tray. Keep it frozen for up to 2 months. When you’re ready to use it, let it thaw in the fridge overnight—then bake it like normal.

Storing Leftovers

Got extras? No problem. Keep any leftovers in a sealed container in the fridge. They’ll stay fresh for about 4 days. To reheat, microwave a portion or warm it in the oven at 350°F for around 10 minutes.
