Rosemary Chicken Lasagna Layers Ingredients
Get ready to savor the deliciousness of Rosemary Chicken Lasagna Layers with this simple ingredient guide!
For the Béchamel Sauce
- Olive Oil – Adds moisture and flavor; substitute with vegetable oil if needed.
- Minced Garlic – Provides aromatic depth; fresh is preferred, but garlic powder can be used in a pinch.
- Unsalted Butter – Forms the base of the béchamel sauce; use salted butter if that’s what you have on hand.
- All-Purpose Flour – Used to create a roux for the béchamel; gluten-free flour can substitute for a gluten-free option.
- Whole Milk – Provides creaminess; can substitute with lower-fat or dairy-free alternatives, though consistency may vary.
- Nutmeg – Adds warmth to the béchamel; freshly grated is best, but ground nutmeg works well too.
- Parmesan Cheese – Enhances creaminess and flavor in the béchamel; Pecorino Romano can be a great alternative.
For the Lasagna Layers
- Shredded Chicken – Acts as the main protein source; rotisserie chicken is an excellent time-saver.
- Baby Spinach – Adds nutrition and color; feel free to substitute with any leafy green like kale or Swiss chard.
- No-Boil Lasagna Noodles – Save time and simplify the cooking process; regular noodles can be used if precooked.
- Mozzarella Cheese – Provides that melty goodness; low-fat mozzarella can be used for a lighter option.
Each ingredient plays a vital role in creating the comforting and satisfying layers of this lasagna. Let’s get cooking!
Step‑by‑Step Instructions for Rosemary Chicken Lasagna Layers
Step 1: Preheat the Oven
Start by preheating your oven to 375°F (190°C). This ensures that your Rosemary Chicken Lasagna Layers will bake evenly and achieve the perfect golden-brown top. While the oven heats up, gather your ingredients, including shredded chicken, béchamel sauce, and lasagna noodles, so you’ll be ready for assembly.
Step 2: Sauté Aromatics
In a skillet, heat 2 tablespoons of olive oil over medium heat. Once the oil is shimmering, add in 2 minced garlic cloves and 1 tablespoon of freshly chopped rosemary. Sauté for about 1 minute until fragrant, taking care not to let the garlic burn. This aromatic base will add depth to the layers of your lasagna.
Step 3: Make the Béchamel Sauce
In a saucepan, melt 4 tablespoons of unsalted butter over medium heat. Once melted, whisk in ¼ cup of all-purpose flour to create a roux, cooking for 1 minute until bubbly. Gradually whisk in 3 cups of whole milk, stirring constantly for 5–7 minutes until the mixture thickens and coats the back of a spoon, then season with a pinch of nutmeg and fold in ½ cup of grated Parmesan cheese until melted.
Step 4: Combine Chicken and Spinach
Remove the béchamel from heat, and carefully mix in 2 cups of shredded chicken and 2 cups of baby spinach. Stir gently until the spinach wilts and the chicken is well coated. This combination enriches your Rosemary Chicken Lasagna Layers by adding protein and vibrant greens.
Step 5: Layer the Ingredients
In a 9×13 inch baking dish, start by spreading a thin layer of the béchamel sauce across the bottom. Place a layer of no-boil lasagna noodles on top, followed by half of the chicken-spinach mixture. Pour another layer of béchamel sauce and sprinkle with mozzarella cheese. Repeat the layers until all ingredients are used, finishing with noodles, béchamel, and a generous topping of mozzarella and remaining Parmesan.
Step 6: Bake the Lasagna
Cover the baking dish tightly with aluminum foil to prevent excessive browning of the cheese. Bake the lasagna in the preheated oven for 30 minutes. After that, carefully remove the foil and continue baking for an additional 10-15 minutes until the top is gently golden and bubbly. The aroma should fill your kitchen with a sense of warmth!
Step 7: Allow to Rest
Once the Rosemary Chicken Lasagna Layers are baked to perfection, remove them from the oven. Let the lasagna rest for at least 10 minutes before slicing. This resting time will allow the layers to set nicely, making it easier to serve and enhancing the overall flavor as the ingredients meld together beautifully.

Rosemary Chicken Lasagna Layers Recipe FAQs
How do I choose the right chicken for my lasagna?
Absolutely! When selecting chicken, opt for cooked, shredded chicken, such as rotisserie chicken for convenience. If using raw chicken, ensure it’s cooked thoroughly before shredding it. Look for fresh, plump pieces without any dark spots; this indicates freshness and best flavor.
What is the best way to store leftover lasagna?
Leftovers can be stored in an airtight container in the refrigerator for up to 3-4 days. If you’re looking to enjoy it later, freeze your lasagna tightly wrapped in plastic wrap, then aluminum foil. This way, you can delight in your comforting Rosemary Chicken Lasagna Layers for up to 3 months!
Can I freeze lasagna before baking?
Very! To freeze your assembled lasagna, cover it tightly with plastic wrap and foil. It’s best to freeze before baking, so the layers maintain their texture. When you’re ready to enjoy, bake it directly from frozen, just add about 15-20 minutes to the cooking time for thorough heating.
What if my béchamel sauce is lumpy?
Don’t worry; it can happen! If you find lumps in your béchamel, use a whisk or an immersion blender to smooth it out. If it becomes too thick, whisk in a little more warm milk to reach your desired consistency. Remember, constant whisking while cooking helps prevent lumps in the first place!
Are there dietary considerations I should keep in mind for my guests?
Absolutely! This recipe can easily be tailored to be gluten-free by using gluten-free lasagna noodles and flour for the béchamel sauce.
