Rosemary Chicken Lasagna Layers Ingredients
For the Béchamel Sauce
- Olive Oil – Ideal for sautéing garlic and rosemary; substitute with avocado oil for a high smoke point.
- Minced Garlic – Adds savory depth and aroma; in a pinch, you can use garlic powder.
- Fresh Rosemary – Brings fragrant herbal notes; if unavailable, dried rosemary can be used (just a little less, as it’s more potent).
- Unsalted Butter – Essential for a rich roux; margarine or a butter alternative works as a substitute.
- All-Purpose Flour – Necessary for thickening the béchamel; for a gluten-free option, use a gluten-free flour blend.
- Whole Milk – Creates a creamy base for the sauce; almond or oat milk serves as a dairy-free substitute.
- Nutmeg – Adds warmth to the béchamel; omit if you don’t have it on hand.
- Grated Parmesan Cheese – Enhances richness in the sauce; Pecorino Romano offers a sharper flavor if desired.
For the Lasagna Layers
- Shredded Chicken – The main protein; opt for rotisserie chicken for convenience or use poached chicken breasts.
- Baby Spinach – Optional ingredient for nutrition and color; kale or Swiss chard can be substituted.
- No-Boil Lasagna Noodles – Structural component that absorbs moisture while baking; regular noodles can be used if pre-cooked.
- Mozzarella Cheese – For a gooey, melty topping; Provolone is a good alternative for a different flavor profile.

Step‑by‑Step Instructions for Rosemary Chicken Lasagna Layers
Step 1: Preheat the Oven
Begin by preheating your oven to 375°F (190°C). This step is crucial to ensure that your Rosemary Chicken Lasagna Layers bake evenly and develop that golden-brown, bubbling crust we all love. While the oven is heating up, gather your utensils, including a large skillet, a saucepan, and a 9×13-inch baking dish, to streamline the cooking process.
Step 2: Sauté Aromatics
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 2 minced garlic cloves and 1 tablespoon of chopped fresh rosemary, sautéing them for about 1 minute, until fragrant. This will infuse the oil with aromatic flavors that will shine throughout your lasagna. Keep an eye on the garlic to prevent burning, as burnt garlic can turn bitter.
Step 3: Prepare the Béchamel Sauce
In a medium saucepan over medium heat, melt 4 tablespoons of unsalted butter. Whisk in 1/4 cup of all-purpose flour to create a roux, cooking for 1-2 minutes until it turns a light golden color. Gradually pour in 2 cups of whole milk, stirring constantly for 5-7 minutes until the mixture thickens. Season it with a pinch of nutmeg and stir in 1 cup of grated Parmesan cheese for that creamy, dreamy béchamel sauce.
Step 4: Combine Chicken and Sauce
In a large bowl, mix the cooked shredded chicken (about 2 cups) and optional chopped baby spinach (1 cup) with the béchamel sauce. This combination not only adds moisture but also brings vibrant color and nutrition to your Rosemary Chicken Lasagna Layers. Ensure every piece of chicken is coated in the luscious sauce for maximum flavor.
Step 5: Layer the Ingredients
In your pre-greased 9×13-inch baking dish, begin layering the ingredients. Start with a thin layer of the béchamel sauce at the bottom, followed by a layer of no-boil lasagna noodles. Then, add one-third of the chicken mixture, followed by one-quarter of the remaining béchamel sauce and a sprinkle of mozzarella cheese. Repeat this layering process twice for a hearty, layered effect.
Step 6: Finish with Toppings
For the final assembly, top the last layer of noodles with the remaining béchamel sauce, an even spread of mozzarella, and an additional sprinkle of Parmesan cheese. This layer will create the deliciously gooey, cheesy crust that complements the flavors and makes your Rosemary Chicken Lasagna Layers irresistible.
Step 7: Bake Until Golden
Cover the baking dish with aluminum foil and place it in the preheated oven. Bake the lasagna for 30 minutes, then carefully remove the foil and continue baking for another 10-15 minutes. Look for a bubbling, golden top—a delicious signal that it’s time to take out your beautiful Rosemary Chicken Lasagna Layers from the oven.
Step 8: Rest Before Serving
Allow your lasagna to rest for 10 minutes after baking. This resting time helps the layers set and makes it easier to slice into perfect servings. As it cools, the wonderful aromas will fill your kitchen, inviting everyone to gather around the table for a comforting meal full of hearty flavors.

Expert Tips for Rosemary Chicken Lasagna Layers

Ingredient Substitution: Don’t be afraid to substitute ingredients. Use gluten-free noodles or alternative greens to cater to dietary needs without sacrificing flavor in your Rosemary Chicken Lasagna Layers.
Check for Bubbles: Keep an eye on the lasagna in the final baking stage; a bubbling, golden top signifies that it’s ready to be enjoyed, so don’t rush this moment!

Rosemary Chicken Lasagna Layers Recipe FAQs
How do I choose the best rosemary for my lasagna?
Absolutely! For the best flavor, opt for fresh rosemary with vibrant green leaves and a fragrant aroma. Avoid any that appears wilted or has dark spots, as these can indicate aging or spoilage. If fresh isn’t available, dried rosemary can work in a pinch—just use about one-third the amount since it’s more potent.
What is the best way to store leftover lasagna?
Leftovers can be stored in an airtight container in the fridge for up to 3-4 days. Make sure the lasagna has cooled completely before sealing to keep it fresh and prevent sogginess. You can also place a piece of parchment paper between the lid and the container to help moisture escape!
Can I freeze Rosemary Chicken Lasagna Layers?
Certainly! To freeze, first allow the lasagna to cool completely. Then, wrap it tightly in plastic wrap followed by aluminum foil to prevent freezer burn. It can be frozen for up to 3 months. When ready to enjoy, thaw it in the fridge overnight and reheat in a preheated oven at 350°F (175°C) for about 25-30 minutes until warmed thoroughly.
What should I do if my béchamel sauce is too thick?
If your béchamel sauce turns out too thick, don’t worry! Add a splash of milk gradually while whisking until you reach your desired consistency. Remember, the sauce should be smooth and pourable. If needed, you can also blend it briefly in a blender for an ultra-creamy finish.
Is this recipe safe for those with dairy allergies?
For those with dairy allergies, you can modify the recipe by using non-dairy alternatives. Replace whole milk with almond or oat milk and use dairy-free cheese options. For the béchamel sauce, consider a mix of dairy-free butter and a gluten-free flour blend for a delicious and safe alternative.
