Ingredients You’ll Need

• 12 oz. uncooked penne pasta
• 2 cups cooked, shredded chicken
• 2 cups Alfredo sauce
• 2 cups chicken broth
• 1 cup shredded mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 1 cup frozen peas
• Salt and pepper to taste
• Fresh parsley, chopped for garnish

Substitution Options

Not a fan of penne? Swap it out for fusilli or rigatoni. If you’re vegetarian, skip the chicken and add sautéed mushrooms or zucchini. For a lighter version, use low-fat Alfredo sauce or Greek yogurt mixed with a bit of cream cheese. And if you’re out of mozzarella, try cheddar or provolone instead.

Step 1: Preheat and Prep

Start by preheating your oven to 425°F (220°C). Grab a large baking dish and toss in the uncooked penne pasta, shredded chicken, Alfredo sauce, chicken broth, and frozen peas. Stir everything together until it’s evenly coated. The mixture will look creamy and inviting, with little green specks of peas peeking through. Season with salt and pepper to taste. Pro tip: Taste the sauce before adding seasoning—it might already have enough salt.

Step 2: Cover and Bake

Cover the dish tightly with aluminum foil. This step is crucial because it traps steam, ensuring the pasta cooks evenly without drying out. Pop it in the oven for 25 minutes. While it bakes, your kitchen will fill with the rich aroma of Alfredo sauce and melted cheese. Trust me, it’s hard not to sneak a peek!

Step 3: Add the Cheesy Topping

After 25 minutes, remove the foil and sprinkle the mozzarella and Parmesan cheese on top. Return the dish to the oven, uncovered, for another 10 minutes. Watch as the cheese melts into a golden, bubbly layer. It’s the kind of sight that makes your mouth water instantly. Chef’s tip: For extra creaminess, drizzle a little more Alfredo sauce over the top before adding the cheese.

Step 4: Cool and Garnish

Once the casserole is done, let it rest for a few minutes. This helps the flavors meld together and makes serving easier. Sprinkle some fresh parsley on top for a pop of color and freshness. The contrast between the vibrant green parsley and the creamy white casserole is just beautiful.

Chef’s Secret

Here’s a little trick I learned: Let the casserole rest for at least 5 minutes before digging in. This allows the sauce to thicken slightly, making each bite perfectly creamy and cohesive.

An Interesting Fact About Alfredo Sauce

Did you know Alfredo sauce was invented in Rome in the early 1900s? A chef named Alfredo Di Lelio created it to soothe his pregnant wife’s nausea. Talk about love in a bowl!

Necessary Equipment

• Large baking dish
• Mixing spoon
• Measuring cups
• Aluminum foil

Storage Tips

To store leftovers, let the casserole cool completely before covering it with plastic wrap or transferring it to an airtight container. It keeps well in the fridge for up to 3 days. When reheating, add a splash of milk or chicken broth to keep it moist. Freezing is also an option—just thaw overnight in the fridge before reheating.

If you’re meal prepping, divide the casserole into individual portions. This way, you can grab a serving whenever you need a quick lunch or dinner. Pro tip: Label each container with the date to keep track of freshness.

For best results, avoid freezing the casserole with fresh parsley on top. Add the garnish after reheating for maximum flavor and presentation.

Tips and Advice

To elevate this dish, use freshly grated Parmesan instead of pre-shredded. Freshly grated cheese melts better and has a richer flavor. Another tip: Don’t overcook the pasta during the initial bake. It will continue to soften as it rests.

Presentation Ideas

• Serve in a colorful ceramic dish for a rustic touch.
• Garnish with extra parsley or a sprinkle of red chili flakes for a pop of color.
• Pair with a side salad or garlic bread for a complete meal.

Healthier Alternatives

Here are six ways to make this casserole healthier:

1. Use Whole Wheat Pasta: Swap regular pasta for whole wheat to add fiber.
2. Add More Veggies: Include spinach, broccoli, or roasted bell peppers.
3. Lighten the Sauce: Use a low-fat Alfredo or make your own with Greek yogurt.
4. Go Gluten-Free: Use gluten-free pasta to accommodate dietary needs.
5. Reduce Cheese: Cut back on mozzarella and rely on Parmesan for flavor.
6. Use Turkey Instead of Chicken: Ground turkey is leaner and works beautifully.

Mistake 1: Overcooking the Pasta

One common mistake is cooking the pasta too long during the baking process. Remember, the pasta continues to cook as it rests. To avoid mushy pasta, check for doneness a few minutes before the timer goes off. Pro tip: Aim for al dente texture during the initial bake.

Mistake 2: Skipping the Resting Time

Another error is skipping the resting period. Without it, the sauce may be too runny, and the flavors won’t blend as well. Patience pays off here—let it sit for at least 5 minutes before serving.

Mistake 3: Using Pre-Shredded Cheese

Pre-shredded cheese often contains anti-caking agents that prevent it from melting smoothly. Always opt for block cheese and shred it yourself for the creamiest results.
