What Is Chicken Rosemary Lasagna?
Chicken rosemary lasagna is a white lasagna made with tender chicken, sautéed mushrooms, spinach, and fresh rosemary, all layered between pasta sheets with a rich béchamel sauce, ricotta, mozzarella, and Parmesan. Instead of tomato sauce, you get a creamy, herb-infused sauce that clings to every bite.
It’s comforting without being heavy, and the rosemary gives it a sophistication that makes it feel special enough for company but easy enough for a Sunday dinner. You can prep it ahead, bake it when you’re ready, and everyone goes back for seconds.
Why You’ll Love This Creamy Chicken Lasagna Recipe
This recipe hits all the right notes. It’s creamy, savory, and packed with flavor without relying on marinara. The rosemary is the star here, and it doesn’t overpower—it just makes everything taste more alive.
The chicken stays tender, the mushrooms add earthiness, and the spinach sneaks in some greens without anyone complaining. The ricotta mixture with lemon zest brightens everything up, and the béchamel ties it all together in this silky, dreamy way.
It’s also flexible. You can make it vegetarian, swap the herbs, use rotisserie chicken for a shortcut, or even try egg roll wrappers instead of pasta for a lighter texture. And it reheats beautifully, so leftovers are actually exciting.

Instructions
- Preheat oven to 400F
- If using dry pasta start your salted water to a boil, and par-cook the lasagna noodles to aldente.
- Cut chicken into 1/2 inch, bite-size pieces and season with 1 teaspoon salt and cracked pepper to taste. Saute in a skillet, on medium heat, with 1-2 tablespoons olive oil until golden brown, and cooked through. Place chicken in a bowl and set aside. Wipe out the pan and add a little more oil. Add mushrooms and onion and saute until tender, on med heat, about 7 min. Add garlic and rosemary, and saute 2 more minutes. Season with salt and pepper and lower heat to med-low, and saute until mushrooms release their liquid. Add chopped spinach, stir until wilted and add this to the chicken. Set aside.
- In a medium saucepan melt butter on medium-low heat. Add flour and stir for 2-3 minutes on med heat until flour is golden. Whisk in milk one cup at a time. Add rosemary and stir constantly ( do not walk away) until it just comes to a simmer- this will thicken it. Add salt, nutmeg and white pepper. Stir until incorporated, set aside.

Ingredient Notes and Substitutions
Chicken: You can absolutely use rotisserie chicken here to save time. Just shred it and skip the browning step. For a vegetarian version, swap the chicken for more mushrooms, white beans, or even roasted butternut squash.
Rosemary: Fresh rosemary has a brighter, more vibrant flavor, but dried works in a pinch. If you’re not a rosemary fan, try thyme or sage instead—they both bring earthy, savory notes without the pine-like intensity.
Mushrooms: Baby bellas, cremini, or even shiitakes work beautifully here. If you’re not into mushrooms, just add more chicken or try zucchini or bell peppers for bulk and flavor.
Milk: Whole milk makes the creamiest béchamel, but you can use 2% or even plant-based milk like oat or almond. Just know that thinner milks might make a slightly less rich sauce, so you may need to simmer it a bit longer.
Lasagna noodles: Fresh lasagna sheets are incredible if you can find them, but par-boiled dry noodles work perfectly. The egg roll wrapper trick is real—it makes a lighter, more delicate lasagna that’s surprisingly good.
Cheese: The ricotta-mozzarella-Parmesan combo is classic, but you can sub in fontina, Gruyère, or even a little goat cheese for a tangy twist.
Step-by-Step Instructions for Chicken Rosemary Lasagna
This recipe has a few moving parts, but none of them are complicated. You’ll cook the chicken and veggies, make a quick béchamel, mix up the ricotta, and then layer everything together. It’s all about building flavor in each step.
- Preheat your oven to 400°F. This ensures it’s hot and ready when your lasagna is assembled.
- If using dry pasta, bring a large pot of salted water to a boil and par-cook the lasagna noodles until al dente. Drain and lay them flat on a clean kitchen towel so they don’t stick together. Fresh noodles don’t need this step.
- Cut the chicken into ½-inch bite-sized pieces and season with 1 teaspoon salt and cracked black pepper. Heat 1 to 2 tablespoons of olive oil in a large skillet over medium heat. Add the chicken in a single layer and sauté until golden brown and cooked through, about 6 to 8 minutes. Transfer the chicken to a bowl and set aside.
- Wipe out the pan and add a little more olive oil. Add the sliced mushrooms and diced onion. Sauté over medium heat until tender, about 7 minutes. The mushrooms will shrink and release their liquid—let that cook off.
- Add the chopped garlic and 1 tablespoon of fresh rosemary to the mushroom mixture. Sauté for 2 more minutes until fragrant. Season with salt and pepper to taste.
- Lower the heat to medium-low and add the chopped spinach. Stir until wilted, about 1 to 2 minutes. Add this veggie mixture to the bowl with the chicken and set aside.
- In a medium saucepan, melt 4 tablespoons of butter over medium-low heat. Add 4 tablespoons of flour and stir constantly for 2 to 3 minutes until the mixture is golden and smells nutty. This is your roux.
- Whisk in the milk one cup at a time, stirring constantly. Don’t walk away—this is where the sauce thickens. Add the second tablespoon of chopped rosemary and keep stirring until the sauce just comes to a simmer. It should coat the back of a spoon.
- Add 1 ¼ teaspoons kosher salt, ½ teaspoon nutmeg, and ¼ teaspoon white pepper to the béchamel. Stir until incorporated, then remove from heat and set aside.
- In a medium bowl, whisk together the ricotta, egg, lemon zest, a few cracks of black pepper, and ¼ teaspoon nutmeg. This mixture should be smooth and creamy.
- Butter or grease a 9×13-inch baking dish. Pour ¾ cup of béchamel sauce into the bottom and spread it out evenly. This prevents sticking and adds creaminess to the base.
- Place one layer of lasagna noodles over the sauce. Cover with half of the ricotta mixture, spreading it evenly with a spatula.
- Top the ricotta with half of the chicken and mushroom filling. Sprinkle with one-third of the Parmesan and one-third of the mozzarella. Drizzle with about 1 cup of béchamel sauce.
- Repeat the layers: another layer of noodles, the remaining ricotta, the remaining chicken and mushroom filling, another third of the mozzarella and Parmesan, and another cup of béchamel. Press down gently so everything settles. If you’re using truffle oil, drizzle a little here—it’s optional but amazing.
- Top with the final layer of lasagna noodles. Pour the remaining béchamel sauce over the top and spread it evenly. Sprinkle with the last of the mozzarella and Parmesan, and finish with a little chopped rosemary for color and flavor.
- Cover the dish tightly with parchment paper, then foil. The parchment prevents the foil from touching the cheese, which can leach aluminum and cause discoloration. Bake at 400°F for 40 minutes, or until the lasagna is hot and bubbly.
- Remove the parchment and foil and bake uncovered for another 10 to 15 minutes, until the top is golden and slightly crispy around the edges. Let the lasagna rest for 10 to 15 minutes before cutting so the layers set up and don’t slide apart.
Expert Tips for Perfect Chicken Rosemary Lasagna
Don’t skip the resting time. I know it’s tempting to dig in right away, but letting the lasagna sit for 10 to 15 minutes after baking makes all the difference. The layers firm up, the sauce thickens slightly, and you get clean, beautiful slices instead of a saucy mess.
Use parchment under the foil. This little trick prevents the foil from sticking to the cheese and keeps your top layer looking gorgeous. It also avoids any metallic taste or aluminum transfer.
Season each layer. Don’t rely on the béchamel to carry all the flavor. Season your chicken, your veggies, and your ricotta mixture separately. Layered seasoning builds depth.
Cook your béchamel just until it thickens. You want it to coat the back of a spoon, not turn into paste. If it gets too thick, whisk in a little more milk. If it’s too thin, simmer it a bit longer.
Fresh rosemary is worth it. Dried rosemary can be woody and sharp if you use too much. Fresh rosemary is more delicate and aromatic, and it blends into the sauce and filling beautifully. If you only have dried, use half the amount and crush it between your fingers first to release the oils.
Taste as you go. This is a simple rule, but it matters. Taste your chicken mixture, your béchamel, and your ricotta. Adjust salt, pepper, and herbs before you layer everything together, because once it’s baked, you can’t fix underseasoned filling.
Variations on This Creamy Chicken Lasagna Recipe
Vegetarian version: Replace the chicken with a mix of roasted vegetables like zucchini, bell peppers, and eggplant, or use white beans and extra mushrooms for protein and texture.
Lighter version: Swap the lasagna noodles for egg roll wrappers. It sounds weird, but it works—they’re thinner, lighter, and almost melt into the sauce. You can also use part-skim ricotta and mozzarella, and make the béchamel with olive oil instead of butter.
Add more greens: Toss in some chopped kale, Swiss chard, or arugula along with the spinach for extra nutrition and color.
Make it richer: Stir a few tablespoons of cream cheese or mascarpone into the ricotta mixture, or drizzle truffle oil between the layers. A little goes a long way.
Change the herbs: If rosemary isn’t your thing, try fresh thyme, sage, or even a mix of Italian herbs. Basil and parsley also work beautifully in white lasagna.
Add some heat: A pinch of red pepper flakes in the chicken mixture or a little fresh cracked black pepper in the béchamel can add a nice kick without overwhelming the dish.
Troubleshooting Common Issues
My béchamel is lumpy. This usually happens if you add the milk too fast or don’t whisk constantly. If it happens, pour the sauce through a fine-mesh strainer or blend it with an immersion blender to smooth it out.
The lasagna is watery. This can happen if your spinach or mushrooms release too much liquid. Make sure you cook the mushrooms until their liquid evaporates, and squeeze out excess moisture from the spinach before adding it. Also, let the lasagna rest after baking—this gives the sauce time to thicken and the layers time to set.
The noodles are too chewy. If you’re using dry noodles, make sure you par-cook them to al dente. They’ll finish cooking in the oven, but if they’re too raw going in, they’ll stay tough. If you’re using fresh noodles and they’re chewy, they might have dried out—cover them with a damp towel until you’re ready to layer.
The top is browning too fast. If the cheese is getting too dark before the lasagna is heated through, tent the dish with foil (parchment first) and continue baking. You can remove it at the end to finish browning.
The layers are sliding apart. This is usually a resting issue. Let the lasagna sit for at least 10 minutes after baking. If your béchamel was too thin, that can also cause sliding—next time, cook it a bit longer before layering.
Storage Instructions for Chicken Rosemary Lasagna
Leftovers are a gift with this recipe. The flavors deepen overnight, and reheating is easy. Store your lasagna properly, and you’ll have delicious meals ready to go all week.
| Storage Method | Duration | Instructions |
|---|---|---|
| Refrigerator | Up to 4 days | Cover tightly with foil or transfer to an airtight container. Reheat individual portions in the microwave or the whole dish in a 350°F oven until warmed through. |
| Freezer | Up to 3 months | Wrap tightly in plastic wrap, then foil, or use a freezer-safe container. Thaw overnight in the fridge before reheating. You can also bake it directly from frozen—just add 20 to 30 minutes to the baking time and keep it covered. |
| Make-ahead (unbaked) | Up to 1 day in fridge | Assemble the lasagna completely, cover tightly, and refrigerate. Bake as directed, adding 5 to 10 minutes if it’s very cold from the fridge. |
To reheat, cover the lasagna with foil and warm it in a 350°F oven for about 20 to 25 minutes, or until heated through. If you’re reheating a single portion, the microwave works fine—just cover it loosely and heat in 1-minute intervals, stirring between, until hot.
