The first time I made Alfredo Lasagna, my youngest looked at the pan and asked, "Is it white lasagna?" I nodded, and he took a bite so big I thought he'd need a nap right there at the table. If your family loves classic lasagna but you're craving something creamier, this is your dish.

I know a white sauce can feel intimidating, and that's completely okay. We'll take it slowly, whisking the butter and flour together until it smells nutty and looks like wet sand, then adding the milk in a steady stream. If it thickens faster than you expect, just lower the heat and breathe. You're doing fine.
This recipe is forgiving by design. You can boil the noodles or use no-boil sheets, make the sauce ahead, and assemble the whole thing the night before. Whether you're feeding a crowd of six or cooking for two with leftovers in mind, Alfredo Lasagna meets you where you are.
Why You'll Love This Recipe
About the Ingredients
12 lasagna noodles (about 12 ounces/340g)
Regular wavy-edged noodles work best; if you prefer, swap in 9 no-boil sheets and add 1/2 cup extra milk to the sauce. Look for noodles without cracks, since broken sheets tear during layering.
1/2 cup (113g) unsalted butter
Salted butter works too; just reduce the added salt in the sauce to 1/4 teaspoon. Buy butter in block form rather than tub spread for a cleaner melt.
1/2 cup (60g) all-purpose flour
This is the thickener, so don't skip it. For a gluten-free version, use a 1-to-1 gluten-free flour blend and whisk a little longer.
4 cups (960ml) whole milk, warmed
Whole milk gives the creamiest body; 2% works but the sauce will be thinner. Warm it in the microwave for 60 seconds so it blends without lumps.
3 cloves garlic, finely minced
Fresh garlic is far better here than powder. If you only have powder, use 3/4 teaspoon and add it with the flour.
2 cups (240g) shredded low-moisture mozzarella, divided
Low-moisture is key so the lasagna doesn't turn watery. Shred a block yourself for a better melt than pre-shredded, which is coated in starch.
1 1/2 cups (360g) whole-milk ricotta
If ricotta feels watery, drain it in a fine-mesh strainer for 15 minutes. Cottage cheese blended smooth is a fine substitute.
1 1/4 cups (125g) freshly grated parmesan, divided
Grate it fresh from a wedge for the best flavor; pre-grated parmesan is drier and saltier. Pecorino Romano is a sharper swap.
1 large egg
The egg binds the ricotta so it sets instead of sliding out. A flax egg (1 tablespoon ground flax + 3 tablespoons water) works for an egg-free version.
1/2 teaspoon salt, plus more for the pasta water
Add salt gradually and taste the sauce before layering. Kosher salt is less salty by volume than table salt, so adjust if needed.
1/4 teaspoon freshly ground black pepper
Fresh-cracked pepper blooms in the warm sauce. A pinch of nutmeg is a lovely classic addition if you have it.
2 tablespoons chopped fresh parsley, for garnish
Flat-leaf parsley is more flavorful than curly. Fresh basil or chives are great substitutes.
Tips & Tricks
- Warm the milk before whisking it into the roux. Cold milk hitting a hot roux is the number one cause of lumpy alfredo, so give it 60 seconds in the microwave and pour slowly while whisking.
- Cook the noodles 2 minutes shy of the package time. They finish cooking in the oven and absorb sauce, so slightly firm noodles keep the layers from turning mushy.
- Let the baked lasagna rest 15 minutes before slicing. This isn't in the bake time, but it's the difference between clean squares and a creamy puddle on the plate.
- Season the ricotta mixture, not just the sauce. A pinch of salt and pepper in the ricotta keeps every layer flavorful instead of bland in the middle.
Pro Tips
Step-by-Step Instructions
1. Preheat and prep
Heat your oven to 375°F (190°C) and butter a 9×13-inch baking dish. Bring a large pot of salted water to a boil while you gather everything.
2. Boil the noodles
Cook the lasagna noodles for 8 minutes, until pliable but still firm, then drain and lay them flat on a sheet pan. They should bend without snapping but resist a fork.
3. Make the alfredo
Melt the butter in a large saucepan over medium heat, whisk in the flour, and cook for 1 minute until it smells nutty and looks like wet sand. Slowly pour in the warm milk, whisking constantly for 5 to 7 minutes until the sauce coats the back of a spoon, then stir in the garlic, salt, pepper, and 1 cup of parmesan.
4. Mix the ricotta
In a medium bowl, stir together the ricotta, egg, remaining 1/4 cup parmesan, and a pinch of salt and pepper until smooth. Set it beside your noodles and sauce like a little assembly line.
5. Layer the lasagna
Spread 1 cup alfredo on the bottom of the dish, add 4 noodles, then half the ricotta, 1 cup mozzarella, and 1 cup alfredo. Repeat once more, then finish with the last 4 noodles and the reserved alfredo.
6. Top with cheese
Scatter the remaining 1 cup mozzarella and 1/4 cup parmesan over the top. The surface should look fully covered so every bite gets a golden cheese pull.
7. Bake covered
Cover with foil and bake at 375°F (190°C) for 30 minutes. The sauce should be bubbling at the edges when you peek underneath.
8. Brown and rest
Uncover and bake another 15 minutes, until the top is golden brown and an instant-read thermometer in the center reads 165°F (74°C). Rest for 15 minutes, garnish with parsley, and slice.
Delicious Variations
Chicken Alfredo Lasagna
fold 3 cups shredded rotisserie chicken into the ricotta layer for extra protein and a heartier bake.
Spinach Alfredo Lasagna
squeeze 10 ounces of thawed frozen spinach dry and stir it into the ricotta for a sneaky green boost.
Mushroom Alfredo Lasagna
saute 12 ounces sliced mushrooms in butter until golden and layer them over the alfredo for an earthy, meatless version.
How to Store Alfredo Lasagna
Refrigerator
Cover tightly or transfer to an airtight container and refrigerate for up to 4 days. Leftovers actually taste better on day two as the layers settle.
Freezer
Wrap individual portions tightly in plastic wrap, then foil, and freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Reheating
Reheat covered at 350°F (175°C) for 20 to 25 minutes, or microwave single slices for 90 seconds with a splash of milk to keep it creamy.
Frequently Asked Questions
Q: Can I make Alfredo lasagna ahead of time?
Yes, you can assemble it up to 24 hours ahead and refrigerate it covered. Add 10 extra minutes to the covered bake time since it starts cold, and don't freeze it before baking if you can help it.
Q: Can I use no-boil lasagna noodles?
Yes, no-boil noodles work well here, but increase the milk in the alfredo by 1/2 cup. Let the assembled dish sit 20 minutes before baking so the noodles soften, and expect a slightly firmer texture.
Q: Why is my alfredo sauce lumpy?
Lumpy alfredo almost always means cold milk hit a hot roux too fast. Warm the milk first and pour it in a slow stream while whisking constantly; if lumps form, whisk over low heat and they'll smooth out.
Q: How do I know when lasagna is done baking?
It's done when the edges bubble and the center reaches 165°F (74°C) on an instant-read thermometer. The top should be golden brown, and a knife inserted in the middle should slide through with little resistance.
Q: Is Alfredo lasagna the same as white lasagna?
Essentially yes, white lasagna is just lasagna made without tomato sauce, and alfredo is the creamy white sauce used here. Some versions add ricotta and mozzarella exactly like this one, so the names are often used interchangeably.
I hope this creamy Alfredo Lasagna becomes a cozy favorite in your kitchen, whether it's a Sunday dinner or a make-ahead weeknight win. Take your time with the sauce, trust your senses over the clock, and remember that a slightly imperfect slice still tastes wonderful. If you make it, I'd love to hear how your family reacted.
