Ingredients You’ll Need

These ingredients are simple yet incredibly important for building layers of flavor, texture, and creaminess. Each one plays a unique role — from the tender cooked chicken adding protein, to the lush Alfredo sauce soaking into every noodle, and the cheeses creating that irresistible golden crust on top.

• 3 boneless skinless chicken breasts (cooked and shredded): Provides juicy, tender meat that complements the creamy sauce.
• 2 jars (15 oz each) Alfredo sauce: Choose a good quality one like Bertolli for authentic flavor and silky texture.
• 1 cup water: Helps thin the sauce slightly so the pasta cooks evenly in the slow cooker.
• 1 tablespoon minced garlic: Adds a fragrant, savory kick to every bite.
• 1 teaspoon salt: Enhances all the flavors without overpowering.
• 1 teaspoon pepper: Brings a subtle spice and depth.
• 16 oz uncooked penne pasta: The perfect pasta shape to hold onto the creamy sauce.
• 3 cups shredded Mozzarella cheese: Melts beautifully for that gooey, stretchy cheese factor.
• 1/4 cup Parmesan cheese: Sprinkled between layers for a sharp, nutty flavor boost.
• Chopped parsley (optional): A fresh, colorful garnish to brighten the final dish.

How to Make Crock Pot Chicken Alfredo Casserole Recipe

Step 1: Prepare the Alfredo Mixture

Start by mixing the Alfredo sauce, water, minced garlic, salt, and pepper together in a bowl. This simple mixture forms the creamy base that will infuse the pasta with rich flavor as it cooks.

Step 2: Coat the Pasta

Stir the uncooked penne pasta into the Alfredo mixture, making sure every piece is well coated. This ensures the noodles will absorb the sauce perfectly during the slow cooking process.

Step 3: Prep the Crock Pot

Spray your 6-quart slow cooker with non-stick spray. This little step makes a big difference when it comes to easy cleanup and preventing the casserole from sticking as it cooks.

Step 4: Build the First Layer

Place half of the penne and Alfredo mixture into the bottom of the crock pot. This foundational layer sets the stage for all the delicious layers that will follow.

Step 5: Add the First Layer of Chicken

Scatter half of your cooked, shredded chicken evenly over the pasta layer. This protein layer pairs perfectly with the creamy noodles below.

Step 6: Cheese It Up

Sprinkle 1 cup of shredded Mozzarella cheese and about 1/8 cup of Parmesan cheese over the chicken. This adds gooey, melty texture and sharpness to balance the richness.

Step 7: Repeat the Layers

Repeat the penne mixture layer, then top with the remaining chicken, another cup of Mozzarella, and another sprinkle of Parmesan cheese. Layering helps build depth in flavor and texture throughout the casserole.

Step 8: Slow Cook to Perfection

Put the lid on the crock pot and cook on low for 2 1/2 to 3 hours. The slow heat will tenderize the pasta and meld the flavors beautifully without any fuss.

Step 9: Melt the Top Cheese

Remove the lid and sprinkle the final cup of Mozzarella cheese on top. Return the lid just for a few minutes until this last layer melts into an irresistible golden blanket.

Step 10: Garnish and Serve

Finish with a sprinkle of fresh chopped parsley for a pop of color and freshness. Your Crock Pot Chicken Alfredo Casserole Recipe is now ready to wow your taste buds!

Make Ahead and Storage

Storing Leftovers

Keep any leftovers in an airtight container in the refrigerator for up to 3 days. The casserole’s flavors actually deepen overnight, making it a fantastic next-day meal that reheats beautifully.

Freezing

This Crock Pot Chicken Alfredo Casserole Recipe freezes wonderfully. Just cool completely, portion into freezer-safe containers, and freeze for up to 2 months. When you’re ready, thaw overnight in the fridge before reheating.

Reheating

Reheat leftovers covered in the microwave or in a 350°F oven until warmed through. Adding a splash of milk or cream before reheating helps maintain that lush, creamy texture you love.

FAQs

Can I use store-bought rotisserie chicken instead of cooking breast?

Absolutely! Using rotisserie chicken is a great shortcut that adds extra flavor and saves time. Just shred the meat and layer it into your casserole as usual.

What if I want to add vegetables to this casserole?

Feel free to toss in some chopped spinach, mushrooms, or broccoli before cooking for a veggie boost. Just be mindful of added moisture to avoid a soggy casserole.

Can I make this recipe in an Instant Pot instead?

While this specific recipe is designed for a slow cooker, you could adapt it for an Instant Pot on the slow cook or pressure cook setting. Just keep a close eye on the pasta cooking time to avoid overcooking.

Is it okay to substitute different pasta?

Penne works great because its tubes hold the sauce well, but you can swap in other sturdy pasta shapes like rigatoni or shells depending on your preference.

How can I make this casserole dairy-free or vegan?

Switch out the cheeses and Alfredo sauce for dairy-free or vegan alternatives. Use shredded plant-based “mozzarella” and a rich cashew or cauliflower Alfredo sauce to keep things creamy and delicious.
