Ingredients You’ll Need

Here’s everything you need to make this homemade Chicken Alfredo Lasagna.

• Oven-ready lasagna noodles (15): These noodles make preparation easier because they don’t need to be boiled before assembling the lasagna.
• Rotisserie chicken (4 cups, roughly chopped): Provides tender, juicy chicken and saves time. You can also use leftover cooked chicken.
• Unsalted butter (1/2 cup): Creates the rich base for the homemade Alfredo sauce.
• Garlic (2 large cloves, minced): Adds aromatic flavor and enhances the creamy sauce.
• All-purpose flour (1/3 cup): Helps thicken the Alfredo sauce to the perfect consistency.
• Half-and-half (5 cups): Gives the sauce its smooth, creamy texture. Heavy cream can also be used for extra richness.
• Salt (1 1/2 teaspoons, divided): Enhances the flavor of the sauce and ricotta filling.
• Black pepper (1/2 teaspoon): Adds mild warmth and balances the richness of the cheese.
• Ground nutmeg (1/8 teaspoon): Provides subtle warmth and a classic flavor that complements creamy sauces.
• Parmesan Reggiano cheese (1 1/2 cups, grated): Adds a savory, nutty flavor to the Alfredo sauce and lasagna layers.
• Frozen chopped spinach (one 10-ounce package): Adds color, flavor, and a little freshness to the creamy ricotta filling.
• Whole milk ricotta cheese (one 15-ounce container): Creates a soft, creamy layer between the noodles.
• Large egg (1): Helps bind the ricotta mixture so it holds together when sliced.
• Dry Italian seasoning (2 teaspoons): Adds a delicious blend of herbs.
• Onion powder (1 teaspoon): Brings extra savory flavor to the ricotta mixture.
• Crushed red pepper flakes (1/2 teaspoon): Add a gentle kick of heat. You can substitute 1/4 teaspoon black pepper for a milder version.
• Low-moisture shredded mozzarella cheese (4 1/2 cups): Creates the stretchy, golden, cheesy layers that make lasagna irresistible.
• Italian parsley (3–4 tablespoons, chopped): Adds a fresh finish and a pop of color when serving.

How to Make Chicken Alfredo Lasagna

This creamy chicken Alfredo lasagna comes together in a few simple stages. First, prepare the homemade Alfredo sauce, then mix the ricotta filling before layering everything into a baking dish.

Step 1: Make the Homemade Alfredo Sauce

Place the butter in a heavy-bottomed 4-quart saucepan over medium heat. Once melted, add the minced garlic and cook for about 1 minute, just until fragrant.

Add the flour and whisk constantly until it is fully absorbed into the butter, creating a smooth paste.

Gradually pour in the half-and-half while whisking continuously. Add 1 teaspoon of salt, the black pepper, and ground nutmeg.

Bring the mixture to a gentle boil, whisking constantly. Reduce the heat to low and let the sauce simmer for about 5 minutes, whisking occasionally until it thickens.

Stir in 1 cup of grated Parmesan Reggiano until melted and smooth. Remove the saucepan from the heat and set the Alfredo sauce aside.

Tip: Avoid letting the sauce boil too vigorously. Gentle heat helps keep it smooth and prevents scorching.

Step 2: Prepare the Ricotta-Spinach Filling

In a medium mixing bowl, whisk together the ricotta cheese and egg until combined.

Add the Italian seasoning, onion powder, remaining 1/2 teaspoon of salt, crushed red pepper flakes (or black pepper), and 1/3 cup of grated Parmesan Reggiano.

Mix everything together, then fold in the thawed and thoroughly drained spinach.

Set the filling aside while you prepare the baking dish.

Important: Make sure you squeeze as much moisture as possible from the thawed spinach. Excess water can make your lasagna watery.

Step 3: Prepare the Baking Dish

Preheat your oven to 350°F (175°C).

Lightly coat a deep 13 × 9-inch baking dish with nonstick cooking spray.

Divide the oven-ready lasagna noodles into three portions to make assembling the layers easier.

Step 4: Assemble the First Layer

Spread approximately 1/2 cup of Alfredo sauce over the bottom of the prepared baking dish.

Arrange one-third of the lasagna noodles over the sauce in an even layer.

Spread half of the ricotta-spinach mixture over the noodles, followed by 2 cups of chopped rotisserie chicken.

Drizzle approximately one-third of the remaining Alfredo sauce over the chicken, then sprinkle with 1 1/2 cups of shredded mozzarella cheese.

Step 5: Add the Second Layer

Arrange another layer of lasagna noodles over the mozzarella.

Spread the remaining ricotta-spinach mixture evenly over the noodles.

Add the remaining 2 cups of chopped chicken, followed by another one-third portion of the Alfredo sauce.

Sprinkle another 1 1/2 cups of shredded mozzarella cheese over the top.

Step 6: Finish the Lasagna

Place the final layer of lasagna noodles over the second layer.

Pour the remaining Alfredo sauce evenly over the noodles, making sure the edges are covered so they cook properly.

Finish with the remaining 1 1/2 cups of shredded mozzarella cheese and the reserved grated Parmesan Reggiano.

Step 7: Bake Until Hot and Bubbly

Spray a large piece of aluminum foil with nonstick cooking spray and cover the baking dish, with the sprayed side facing the cheese.

Bake in the preheated oven for approximately 55–60 minutes, or until the lasagna is hot throughout and the noodles are tender.

The cooking spray helps prevent the melted cheese from sticking to the foil.

Step 8: Brown the Cheesy Top

Carefully remove the foil and broil the lasagna briefly until the cheese becomes golden and lightly browned.

Keep a close eye on it because the cheese can brown quickly under the broiler.

Remove from the oven and allow the lasagna to rest for 5–10 minutes before slicing.

Garnish with freshly chopped Italian parsley and serve warm.

Tips for Success

A few simple tips can make a big difference when preparing the perfect creamy chicken Alfredo lasagna.

• Drain the spinach thoroughly: Frozen spinach holds a lot of moisture. Squeeze it well before adding it to the ricotta mixture to avoid watery layers.
• Use rotisserie chicken: It’s a convenient shortcut that adds plenty of flavor. Remove the skin and roughly chop or shred the meat before layering.
• Whisk the Alfredo sauce continuously: This helps prevent lumps from forming when adding the flour and half-and-half.
• Use a deep baking dish: A 13 × 9-inch dish that’s approximately 2 1/4 inches deep provides enough room for all the layers.
• Cover while baking: Aluminum foil helps the noodles cook evenly while keeping the top from browning too early.
• Spray the foil: This small step prevents the melted mozzarella from sticking when you remove the cover.
• Let it rest before slicing: Resting for 5–10 minutes helps the creamy layers settle, making it easier to cut neat portions.
• Don’t rush the sauce: Allow it to simmer gently until thickened. A sauce that’s too thin may leave the finished lasagna runny.

Equipment Needed

You only need a few basic kitchen tools to prepare this delicious homemade lasagna.

• 4-quart heavy-bottomed saucepan: For preparing the creamy Alfredo sauce. A medium-sized saucepan also works.
• Whisk: Helps create a smooth sauce without lumps.
• Medium mixing bowl: For preparing the ricotta-spinach filling.
• 13 × 9-inch deep baking dish: Holds all the lasagna layers comfortably.
• Measuring cups and spoons: For accurately measuring the ingredients.
• Cutting board and knife: For chopping the cooked chicken, garlic, and parsley.
• Aluminum foil: Covers the lasagna during baking to prevent excessive browning.
• Spatula or large spoon: Useful for spreading the ricotta filling and Alfredo sauce evenly.

Recipe Variations

This chicken Alfredo lasagna is easy to customize depending on your preferences and what you have available. Here are a few delicious ideas to try.

1. Chicken and Mushroom Alfredo Lasagna

Add sautéed mushrooms to the chicken layers for a delicious earthy flavor. Cook the mushrooms in butter with a little minced garlic until tender and most of their moisture has evaporated before adding them to the lasagna.

2. Spicy Chicken Alfredo Lasagna

If you enjoy a little heat, increase the crushed red pepper flakes or add diced jalapeños to the chicken mixture. Pepper Jack cheese is another great option for adding extra spice.

3. Vegetarian Alfredo Lasagna

Skip the chicken and replace it with sautéed mushrooms, zucchini, spinach, bell peppers, and sun-dried tomatoes. Cook the vegetables first to remove excess moisture, then layer them with the ricotta mixture and Alfredo sauce.

4. Turkey Alfredo Lasagna

Replace the rotisserie chicken with leftover roasted or Thanksgiving turkey. It’s a wonderful way to transform leftover turkey into a completely different and satisfying family dinner.

5. Extra Cheesy Alfredo Lasagna

For an even richer version, add shredded Gruyère or extra mozzarella between the layers. You can also sprinkle a little additional Parmesan cheese over the top before broiling.

What to Serve with Chicken Alfredo Lasagna

Because this lasagna is rich, creamy, and filling, it pairs especially well with fresh vegetables, crisp salads, and light side dishes.

Here are some delicious serving suggestions:

• Garlic bread: Crispy garlic bread is perfect for soaking up every bit of the creamy Alfredo sauce.
• Caesar salad: Crisp romaine lettuce, Parmesan cheese, and creamy dressing provide a refreshing contrast to the rich lasagna.
• Roasted broccoli: Tender broccoli with crispy edges adds freshness and a little crunch.
• Green beans: Lightly sautéed green beans with garlic make a simple and flavorful side.
• Caprese salad: Fresh tomatoes, mozzarella, basil, and balsamic glaze add a bright Italian-inspired touch.
• Roasted asparagus: A simple side of asparagus with olive oil, salt, and black pepper complements the creamy cheese layers.
• Dinner rolls: Soft, warm rolls are wonderful for serving alongside this hearty casserole.

For a beautiful presentation, garnish each slice with fresh Italian parsley and a little extra Parmesan cheese.

Frequently Asked Questions

Can I make Chicken Alfredo Lasagna ahead of time?

Yes! This recipe is perfect for preparing ahead. Assemble the lasagna according to the instructions, cover it tightly, and refrigerate it until you’re ready to bake.

For the best results, prepare it no more than 24 hours in advance. Since the lasagna will be cold when it goes into the oven, allow additional baking time and check that the center is fully heated and the noodles are tender.

Can I use store-bought Alfredo sauce?

Absolutely! Homemade Alfredo sauce gives this chicken lasagna its rich flavor, but store-bought sauce is a convenient shortcut when you’re short on time.

You’ll need approximately 6 cups of prepared Alfredo sauce to replace the homemade version in this recipe.

Do I need to boil oven-ready lasagna noodles?

No. Oven-ready lasagna noodles are designed to cook directly in the casserole. The moisture from the Alfredo sauce helps soften them as the lasagna bakes.

Make sure the noodles are covered with sauce, especially around the edges, to help them cook evenly.

Can I use regular cooked chicken instead of rotisserie chicken?

Yes! Cooked chicken breasts, grilled chicken, poached chicken, or leftover roasted chicken all work well. Use approximately 4 cups of roughly chopped or shredded cooked chicken.

The important thing is to use fully cooked chicken before assembling the lasagna.

How do I store leftover Chicken Alfredo Lasagna?

Allow the lasagna to cool, then transfer leftovers to an airtight container or cover the baking dish tightly.

Refrigerate for up to 3–4 days. Reheat individual portions in the microwave or warm larger portions in a covered oven-safe dish until heated through.

Can I freeze Chicken Alfredo Lasagna?

Yes! You can freeze this lasagna either before or after baking.

For an unbaked lasagna, assemble it in a freezer-safe dish, cover it tightly, and freeze. Thaw overnight in the refrigerator before baking.

For baked leftovers, cool completely and divide into individual portions before freezing. Store in airtight freezer-safe containers for up to 2–3 months for the best quality.
