If you’re one of the people who thinks chicken lasagna is somehow lesser than the classic, this recipe is about to change your mind.
There’s no ricotta, no complicated steps, and no unnecessary fuss — just juicy seasoned chicken, a spinach alfredo sauce that honestly deserves its own dedicated recipe post, and enough melted mozzarella to make the whole thing absolutely worth the effort.
Ingredients Required
For the chicken:
- 6 chicken tenders (or boneless breast, cut into strips)
- 1 tsp salt
- ½ tsp black pepper
- 1 tsp cayenne or chili powder
- 1 tsp garlic powder
- 1 tsp Italian seasoning
- 2 tablespoons olive oil
For the creamy spinach alfredo sauce:
- 5 tablespoons unsalted butter
- ½ medium onion, finely chopped
- 1 tablespoon minced garlic
- 1 tsp salt, ½ tsp pepper, 1 tsp chili flakes, 1 tsp Italian seasoning
- 5 tablespoons all-purpose flour
- 2 cups whole milk
- 1 cup heavy cream
- 1 cup freshly grated Parmesan
- 2 cups chopped spinach
For assembly:
- 14–15 lasagna sheets (almost 1 full box)
- 3–4 cups shredded mozzarella cheese
- Fresh parsley, for garnishing
Notes on the Ingredients
The chicken tenders are worth using over breast where possible — they cook faster, stay juicier, and have a little more natural flavor. Whatever cut you use, don’t skip the resting and tossing step after cooking. Those juices that pool on the chopping board are flavor you’d otherwise leave behind, and tossing the chopped chicken through them takes five seconds.
On the sauce: freshly grated Parmesan is genuinely worth the extra effort here. The pre-grated kind has a drier, powdery texture that doesn’t melt into the sauce the same way, and this sauce is the soul of the whole dish. As for the spinach — yes, you can skip it, but don’t.
It adds color, texture, and a mild earthiness that balances the richness of the cream beautifully. And the flour is non-negotiable; it’s what keeps the sauce from splitting in the oven.
For the lasagna sheets, boil them to al dente only — not all the way through. They’ll continue cooking in the oven, and fully cooked sheets will turn soft and lose their structure in the finished lasagna. Toss them in a little oil after draining to keep them from sticking together while you get everything else ready.
How to Make Chicken Alfredo Lasagna
Boil the lasagna sheets. Cook the sheets according to package instructions until just al dente. Drain, toss with a little oil to prevent sticking, and lay them out separately until needed.
Prepare the chicken. Coat the chicken tenders in all the seasonings and olive oil and rub for a full minute to make sure everything is evenly distributed. Heat a cast iron skillet or non-stick pan over medium-high and cook for about 4 to 6 minutes per side until cooked through and nicely seared on both sides.
Don’t overcook — if in doubt, slice the thickest tender in half; no pink means it’s done. Rest on a chopping board for 5 minutes, then chop into small chunks and toss through the resting juices to reclaim all that flavor. Set aside.
Make the creamy alfredo sauce. Have everything prepped and measured before you start — this sauce moves quickly and needs your attention. Melt the butter in a non-stick pan over medium-high heat and sauté the onion until softened, about 3 to 5 minutes. Add the garlic and cook for another 1 to 2 minutes until fragrant.
Stir in all the seasoning and cook for a minute, then add the flour and toast it for another minute — this step is what prevents a starchy, raw taste in the finished sauce. Add the milk and cream, drop the heat to medium-low, and stir constantly until the sauce thickens to a consistency that coats the back of a spoon.
Don’t take it too far; it will continue thickening in the oven. Turn off the heat and stir in the spinach and Parmesan. Taste and adjust seasoning.
Assemble the lasagna. Preheat the oven to 375°F (conventional, bottom burner only). Spread 2 to 3 tablespoons of sauce across the bottom of a 9×13 inch glass or ceramic baking dish — this prevents the bottom layer from sticking and drying out.
Lay down 3 lasagna sheets in a single layer, cover with a generous amount of sauce, scatter over one-third of the chicken, and finish with approximately ¾ cup of mozzarella. Repeat this process for the second and third layers. For the final layer, cover with the last of the lasagna sheets, spread the remaining sauce over the top, and finish with a full cup of mozzarella.
Bake the lasagna. Before you cover the dish, press 6 to 8 toothpicks into the lasagna at even intervals — these act as tent poles to keep the foil from touching the cheese and tearing off the top layer when you remove it. Cover tightly with foil and bake for 40 minutes.
Remove the foil and switch to the broiler for 2 to 3 minutes, keeping a close eye on it, until the cheese on top is golden and just catching in places. Remove from the oven and rest for 15 minutes before slicing. This rest period is what gives you clean, defined layers rather than a sliding pile of hot filling.
What to Serve With It
The lasagna is rich enough to carry a meal entirely on its own, so the sides just need to provide contrast rather than compete. A crisp green salad with a sharp lemon or red wine vinaigrette is the obvious choice — something clean and acidic that cuts through the cream between bites.
Garlic bread alongside is less a side dish and more a given; the sauce is too good not to have something to mop it up with. If you want a vegetable on the plate, roasted asparagus or broccolini both work beautifully without adding any more richness to an already generous meal.

Ingredients
Method
- Boil lasagna sheets to al dente per package instructions. Toss in oil, lay flat, and set aside.
- Coat chicken in all seasonings and olive oil. Cook in a cast iron or non-stick pan over medium-high heat for 4–6 minutes per side until cooked through and seared. Rest for 5 minutes, then chop into chunks and toss through the resting juices. Set aside.
- Melt butter in a non-stick pan over medium-high heat. Sauté onion until soft (3–5 minutes), then add garlic and cook for 1–2 minutes. Add seasoning and cook for 1 minute. Add flour and toast for 1 minute. Pour in milk and cream, reduce to medium-low, and stir until the sauce thickens enough to coat a spoon. Turn off heat and stir in spinach and Parmesan. Taste and adjust.
- Preheat oven to 375°F (conventional). Spread 2–3 tablespoons of sauce on the bottom of a 9×13 inch baking dish. Layer: 3 lasagna sheets, generous sauce, one-third of the chicken, ¾ cup mozzarella. Repeat for layers two and three. Finish with a final layer of lasagna sheets, remaining sauce, and 1 cup mozzarella.
- Press 6–8 toothpicks into the lasagna to tent the foil. Cover tightly and bake for 40 minutes. Remove foil and broil for 2–3 minutes until golden on top. Rest for 15 minutes before removing toothpicks, garnishing with parsley, and slicing.
Notes
Toothpick tent: Always use the toothpick method under the foil to prevent the cheese from peeling off with it.
