Alfredo Sheet Pan Lasagna

Golden, crispy edges are the best part of any lasagna, and this Alfredo Sheet Pan Lasagna delivers them in every single bite. Layered with creamy alfredo sauce, pesto, seasoned ricotta, spicy Italian sausage, spinach, and plenty of melty mozzarella, this sheet pan lasagna combines the rich comfort of white lasagna with the fresh, herby flavor of pesto.

Behind This Sheet Pan Lasagna Recipe

If you’ve ever found yourself fighting over the crispy corner piece of lasagna, this recipe is for you.

I’ve always believed the golden, caramelized edges are the best part. They’re cheesy, slightly crisp, packed with flavor, and somehow taste even better than the soft center pieces. So instead of making a traditional deep casserole where only a few lucky slices get those coveted edges, I wanted to create a version where almost every bite has them.

The flavor combination is just as exciting. A base of rich alfredo sauce is finished with dollops of creamy pesto alfredo, giving every bite a balance of buttery richness and fresh basil flavor. A few shortcut ingredients like refrigerated alfredo sauce make it weeknight-friendly without sacrificing flavor, while seasoned ricotta, spicy Italian sausage, spinach, and plenty of mozzarella make it taste completely homemade.

Tips From My Kitchen

• Cut the noodles after boiling. It’s much easier to portion the lasagna when the noodles are cooked first and cut into roughly 3-inch squares.
• Dry the spinach well. Squeeze out as much liquid as possible so it doesn’t water down the alfredo sauce.
• Freshly shred your cheese. A block of mozzarella melts much more smoothly than pre-shredded cheese.
• Don’t skip the pesto. Mixing pesto into one layer of alfredo adds incredible flavor without overpowering the dish.
• Let it rest before slicing. Give the lasagna about 10 minutes after baking to let the layers set.
• Make it ahead. Assemble the entire lasagna up to a day in advance, cover tightly, and refrigerate until ready to bake.

Ingredients You’ll Need & Why

This creamy sheet pan lasagna uses a handful of shortcuts and flavorful ingredients to create a restaurant-worthy dinner without all the work of traditional lasagna.

Lasagna Noodles – Cooking the noodles first, then cutting them into small squares, makes layering incredibly easy while creating perfectly portioned bites throughout the pan.

Spicy Italian Sausage – Adds hearty flavor and just enough spice to balance the richness of the alfredo sauce.

Buitoni Alfredo Sauce – Using refrigerated alfredo sauce saves time while still creating a creamy, luxurious white lasagna.

Prepared Pesto – Mixed into one container of alfredo sauce, pesto adds brightness and depth, keeping the dish from feeling too heavy.

Seasoned Ricotta – Garlic powder and Italian seasoning transform plain ricotta into a flavorful, creamy layer that ties everything together.

Mozzarella & Parmesan – Freshly shredded mozzarella creates those irresistible cheese pulls while Parmesan finishes the top with salty, nutty flavor.

How to Make Alfredo Sheet Pan Lasagna

This sheet pan lasagna is all about building thin, cheesy layers so every piece gets plenty of sauce, filling, and crispy golden edges.

Prepare the Noodles and Fillings

Start by boiling the lasagna noodles until al dente, then cut them into smaller squares once they’re cool enough to handle. The pieces should be roughly portion-sized so they layer easily across the sheet pan.

Cook the spicy Italian sausage until browned and crumbled, then squeeze any excess moisture from the spinach so it doesn’t water down the alfredo sauce.

Mix the Ricotta and Pesto Alfredo

Stir the ricotta with garlic powder and Italian seasoning until it’s evenly seasoned.

In a separate bowl, mix one container of alfredo sauce with pesto. This gives you a creamy basil alfredo that gets dolloped throughout the lasagna.

Build the First Layer

Arrange the noodle squares across the bottom of the sheet pan.

Spread plain alfredo sauce over the noodles, then scatter on cooked sausage and spinach. Add dollops of seasoned ricotta across the top, followed by dollops of pesto-alfredo. Finish the first layer with shredded mozzarella.

Add the Second Layer

Add another layer of noodle squares over the cheese.

Spread on the remaining plain alfredo, then add more sausage and spinach. Dollop the remaining ricotta and pesto-alfredo over the top, then finish with the rest of the mozzarella.

Bake Until Golden

Sprinkle with Parmesan and dried parsley, then bake until the cheese is melted, bubbly, and golden around the edges.

Bake Until Golden and Bubbly

Bake the lasagna uncovered at 375°F until the cheese is melted, bubbling, and beginning to turn golden around the edges, about 25–30 minutes.

Allow the lasagna to rest for about 10 minutes before slicing. This gives the layers a chance to settle while still keeping those crispy, cheesy edges intact.

How to Serve & Store Leftovers

This sheet pan lasagna is delicious served with garlic bread, Caesar salad, roasted vegetables, or a simple green salad for a complete meal. The crispy cheesy edges make every serving feel like the best piece of the pan.

Store leftovers covered in the refrigerator for up to 4 days. Reheat individual portions in the microwave or warm larger portions in a 350°F oven until heated through. This lasagna also freezes well for up to 2 months.
