When most people think of baked lasagna, their minds immediately jump to heavy, red-sauce marinara layered with ground beef. While a traditional Bolognese certainly has its place, there is something undeniably luxurious about shifting to a velvety, savory white sauce. This White Chicken Lasagna with Spinach offers a comforting alternative that turns classic comfort food into a lightened, Mediterranean-inspired masterpiece.
Looking at the freshly baked dish, the contrast of textures and colors is irresistible. A slice reveals perfectly structured, tall layers: juicy shredded chicken breast nestled alongside dark green spinach, all encased in a rich garlic parmesan white sauce. The top layer bakes into a deep, golden-brown crust with bubbling browned mozzarella and crispy edges that lock in all the moisture below.
To give this comforting classic an “Easy Mediterranean” twist, we have lightened up the traditional heavy cream roux. By substituting heart-healthy Extra Virgin Olive Oil (EVOO) as the fat base for our béchamel, infusing it with plenty of fresh minced garlic, and combining lean chicken breast with nutrient-packed spinach, you get all the rich, decadent flavor of an authentic white lasagna with a clean, vibrant Mediterranean profile.
4. Why This Mediterranean Twist Works
Traditional white lasagna recipes rely heavily on sticks of butter and heavy whipping cream, which can leave the dish feeling overly dense. Our Mediterranean approach reimagines the foundation while keeping every bit of its indulgent appeal:
- Lighter Béchamel: We replace heavy cream and pure butter with Extra Virgin Olive Oil, minced garlic, and warm milk. This creates a silkier sauce that coats every sheet of pasta without weighing down the palate.
- Time-Saving Shortcuts: By utilizing pre-cooked rotisserie chicken breast and no-boil (oven-ready) lasagna sheets, you shave off 30 minutes of prep work without sacrificing home-cooked quality.
- Nutrient-Dense Greens: Packing the dish with iron-rich spinach and fresh garlic elevates both the nutritional profile and the visual appeal.

5. Mediterranean Diet Swaps & Smart Ingredients
Achieving the ideal texture and taste in a white chicken spinach lasagna with ricotta comes down to balancing high-quality ingredients with smart prep techniques.
The Pasta
You can use traditional lasagna noodles or oven-ready (no-boil) sheets. For an added boost of fiber that fits seamlessly into a Mediterranean lifestyle, whole wheat lasagna sheets offer a nutty flavor profile that pairs exceptionally well with garlic and spinach.
The Protein & Greens
- Shredded Chicken: Skinned, cooked chicken breast or store-bought rotisserie chicken keeps prep effortless. Shredding the meat finely ensures every bite gets an even distribution of protein.
- Spinach Prep: You can use fresh baby spinach (sautéed down) or frozen chopped spinach. The golden rule for spinach is thorough moisture removal to protect your creamy layers.
The Cheese Blend
A classic spinach ricotta layer provides structural stability and creamy depth:
- Whole-Milk or Part-Skim Ricotta: Forms the fluffy, mild base of the filling.
- Low-Moisture Mozzarella: Essential for that iconic stringy cheese pull and golden top crust.
- Aged Parmesan: Adds a sharp, salty, umami bite to both the ricotta mixture and the sauce.
- Optional Greek Twist: Crumble in 1/4 cup of Greek feta into the ricotta filling to transform this dish into a signature greek white chicken lasagna.
The Olive Oil Béchamel
Our garlic parmesan white sauce uses a base of high-quality Extra Virgin Olive Oil, all-purpose flour, fragrant minced garlic, warm milk, a pinch of ground nutmeg, and freshly grated parmesan. The nutmeg is the secret ingredient—it brings out the warm, savory notes of the dairy and garlic.

Step 1: Preparation & Noodle Setup
Preheat your oven to 375°F (190°C) and lightly coat a standard 9×13-inch baking dish with EVOO or non-stick cooking spray. If you choose standard lasagna sheets over oven-ready noodles, boil them in generously salted water until just al dente. Drain immediately, rinse with cold water to stop the cooking process, and lay them flat on sheets of parchment paper so they do not stick together.
Step 2: Whipping Up the Herb & Ricotta Filling
In a large bowl, combine 15 oz of ricotta cheese, 1 large egg (which binds the filling during baking), 10 oz of fully thawed and dried spinach, 2.5 cups of shredded cooked chicken, 1/2 cup of grated parmesan, garlic powder, onion powder, salt, and black pepper. Stir thoroughly until the chicken and greens are uniformly blanketed in the creamy cheese mixture.
Step 3: Crafting the Garlic-Olive Oil Béchamel Sauce
Heat 4 tablespoons of Extra Virgin Olive Oil (or an EVOO-butter blend) in a heavy saucepan over medium heat. Add 4 cloves of finely minced garlic, sautéing for 60 seconds until fragrant—be careful not to brown or burn the garlic. Whisk in 1/4 cup of all-purpose flour to form a smooth paste (roux) and cook for 1 to 2 minutes to cook off the raw flour flavor.
Slowly stream in 3 cups of warm milk while continuously whisking to ensure a silk-smooth finish free of lumps. Bring to a gentle simmer for 5 to 7 minutes until the sauce coats the back of a spoon. Remove from heat, then whisk in 1 cup of grated parmesan cheese, 1/4 teaspoon of ground nutmeg, salt, and pepper until melted and smooth.
Step 4: Layering for Maximum Stability
- Base: Spread 1 cup of warm white sauce evenly over the bottom of your baking dish.
- Layer 1: Arrange 3 to 4 lasagna noodles over the sauce. Evenly spread 1/3 of the chicken-spinach-ricotta filling over the noodles. Drizzle with 1 cup of white sauce and sprinkle 3/4 cup of shredded mozzarella.
- Layers 2 & 3: Repeat the sequence (Noodles $\rightarrow$ Chicken-Ricotta Filling $\rightarrow$ White Sauce $\rightarrow$ Mozzarella) two more times.
- Top Layer: Place the final set of noodles on top. Pour over the remaining white sauce, ensuring all edges of the pasta are covered to prevent drying out. Generously top with the remaining mozzarella and parmesan cheese.
Step 5: Baking to Golden Perfection
Cover the baking dish tightly with aluminum foil sprayed with non-stick cooking spray (this prevents the melted top cheese layer from sticking to the foil). Bake covered at 375°F (190°C) for 25 minutes.
Carefully remove the foil and return the pan to the oven for an additional 20 to 25 minutes. Bake until the top cheese is bubbling vigorously and develops a deep, golden-brown crust.
7. Pro-Tips: How to Avoid a Watery Lasagna
Nothing ruins a beautiful baked pasta faster than a pool of liquid at the bottom of the dish. Here are two critical rules to keep your lasagna firm, neat, and sliceable:
- The Dish Towel Spinach Squeeze: Spinach contains over 90% water. Whether using fresh or frozen spinach, thaw or steam it completely, place it inside a clean kitchen towel or cheesecloth, and wring it forcefully over the sink until no more water droplets escape.
- The 20-Minute Rest Rule: When you pull your lasagna from the oven, the sauces and cheeses will be molten. If sliced immediately, the structure will collapse. Allow the lasagna to rest uncovered at room temperature for 15 to 20 minutes. As it cools slightly, the béchamel thickens and the ricotta sets, giving you clean, photo-worthy slices.

8. Storage, Meal Prep & Freezing Instructions
This lasagna is an ideal candidate for meal preparation and freeze-ahead dinners.
- Freezing Unbaked (Up to 3 Months): Assemble the lasagna in a freezer-safe dish, cover tightly with plastic wrap directly touching the top cheese, and wrap securely in heavy-duty aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before baking according to standard instructions (adding 10 extra minutes if still cold).
- Storing & Reheating Leftovers: Store cooked leftovers in an airtight container in the refrigerator for up to 4 days. To reheat without drying out the white sauce, place individual slices in a baking dish, add a splash of milk over the top, cover with foil, and warm in a 350°F (175°C) oven for 15–20 minutes.
9. What to Serve with White Chicken Lasagna
Because white lasagna is rich and savory, it pairs best with crisp, acidic, and fresh Mediterranean side dishes:
- Crisp Mediterranean Salads: Serve alongside our vibrant Greek Chopped Feta Salad dressed with lemon vinaigrette to cut through the richness of the cheese.
- Roasted Vegetables: Roasted broccolini, charred zucchini, or our roasted PARMESAN ASPARAGUS LEMON AIOLI make fantastic complementary side dishes.
- Crusty Bread: A warm loaf of garlic-rubbed sourdough or artisan bread dipped in Extra Virgin Olive Oil is perfect for soaking up leftover sauce.
10. Frequently Asked Questions
Can I use rotisserie chicken for white chicken lasagna?
Yes! Rotisserie chicken is the best shortcut for this recipe. It is tender, well-seasoned, and easy to shred, saving you considerable prep time while keeping the chicken moist.
What is white lasagna sauce made of?
White lasagna sauce (béchamel) is traditionally made from a roux of butter/olive oil and flour simmered with milk, garlic, parmesan cheese, and a pinch of nutmeg. Unlike red lasagna, it contains no tomatoes or marinara.
Can I make this white chicken lasagna ahead of time?
Absolutley. You can fully assemble the lasagna 24 hours in advance, cover it tightly, and keep it in the refrigerator. When ready to serve, bake it straight from the fridge, adding 5 to 10 minutes to the covered bake time.
How do I keep frozen spinach from ruining the sauce consistency?
Thaw frozen spinach completely and squeeze out all excess moisture using a clean tea towel or cheesecloth. Removing the liquid prevents water from diluting the garlic béchamel and ricotta mixture during baking.
