Ingredients
  

For the Lasagna

  • 12 Ronzoni no-boil lasagna noodles
  • 2 cups mozzarella cheese shredded
  • 1 cup Parmesan cheese grated
  • 1 cup ricotta cheese or substitute with cottage cheese for a lighter option
  • 1 teaspoon garlic powder
  • 1 teaspoon dried oregano
  • ½ teaspoon salt
  • ½ teaspoon black pepper

For the White Sauce (Béchamel Sauce)

  • 4 tablespoons unsalted butter
  • 4 tablespoons all-purpose flour
  • 3 cups whole milk warmed
  • ½ teaspoon nutmeg optional, for added depth
  • ½ teaspoon salt
  • ¼ teaspoon white pepper
  • ½ cup Parmesan cheese grated

Optional Add-Ins for Extra Flavor

  • 1 cup grilled chicken shredded
  • 1 cup sautéed spinach chopped
  • 1 cup mushrooms sautéed

Ingredient Tips for the Best White Sauce Lasagna

  • Use whole milk for a creamier béchamel sauce. If you prefer a richer version substitute half the milk with heavy cream.
  • Shred your own cheese instead of using pre-packaged shredded cheese. It melts more smoothly and enhances the texture.
  • Season each layer lightly to build depth of flavor in every bite.
  • Let the white sauce cool slightly before assembling. This allows it to thicken making layering easier and ensuring an even consistency.

Instructions
 

Step 1: Making the Creamy Béchamel Sauce

  • Start with this smooth, flavorful white sauce—it's the star that ties everything together!
  • Melt 4 tablespoons of butter in a medium saucepan over medium-low heat.
  • Whisk in 4 tablespoons all-purpose flour, stirring gently but constantly, cooking for 1-2 minutes until you have a smooth, golden paste (roux).
  • Gradually pour in 3 cups warm whole milk, whisking continuously to avoid lumps. Cook for about 5 minutes, until the sauce thickens beautifully.
  • Stir in ½ cup grated Parmesan cheese, along with salt, white pepper, and a pinch of nutmeg (optional, but recommended!).
  • Remove from heat, and allow to cool slightly—it'll thicken nicely as it rests.

Step 2: Preparing the Cheese Mixture

  • Blend the cheeses and herbs to create the rich, gooey layers you love:
  • In a bowl, mix together:
  • 1 cup ricotta cheese (or cottage cheese for lighter texture)
  • 1 teaspoon garlic powder
  • 1 teaspoon dried oregano
  • ½ teaspoon salt
  • ½ teaspoon black pepper
  • ½ cup shredded mozzarella cheese
  • Give it a good stir until everything is creamy and well combined.

Step 3: Assembling Your Lasagna Layers

  • Now comes the fun part—layering all that deliciousness into your baking dish.
  • Lightly coat the bottom of a 9x13-inch baking dish with some of your béchamel sauce (just a thin layer to prevent sticking).
  • Lay three Ronzoni no-boil lasagna noodles in the dish, slightly overlapping.
  • Spread an even layer of the ricotta cheese mixture over the noodles, then drizzle with béchamel sauce, and sprinkle generously with mozzarella and Parmesan cheese.
  • Repeat layering (noodles → ricotta mixture → béchamel sauce → cheeses) until all ingredients are used, ending with a top layer of noodles covered by béchamel sauce and topped generously with mozzarella and Parmesan cheese.

Step 4: Baking Your Lasagna to Golden Perfection

  • Cover your assembled lasagna loosely with foil and bake in a preheated oven at 375°F (190°C) for 25 minutes.
  • After 25 minutes, remove the foil and bake uncovered for another 15–20 minutes, or until bubbly and golden on top.
  • For a deliciously crisp finish, broil your lasagna for 2–3 minutes, watching carefully so it doesn't burn.

Step 5: Rest and Enjoy!

  • Allow your baked lasagna to rest for about 10–15 minutes before slicing. This helps it hold its shape beautifully when serving.
  • Finish it off with a sprinkle of freshly chopped parsley or basil, if you'd like an extra pop of freshness.
