White Sauce Lasagna (Lasagna Bianca): A Comforting Italian Classic

I remember the first time I tasted Lasagna Bianca. It wasn’t in a fancy restaurant, but in the cozy, bustling kitchen of my friend Maria’s Nonna. The aroma of creamy béchamel mingling with savory sausage and earthy mushrooms filled the air, promising something special. Nonna Emilia, with flour dusting her apron and a mischievous twinkle in her eye, served a bubbling, golden-brown square. One bite, and I was transported. This wasn’t the tomato-sauce lasagna I knew; it was richer, more delicate, and utterly unforgettable.

Recipe Overview

• Prep Time: 30 minutes
• Cook Time: 25 minutes
• Total Time: 55 minutes
• Servings: 8
• Dietary Type: Not Gluten-Free

Ingredients

• 2 cups frozen peas
• 3 Italian sausages (skinned and broken into bits)
• 1 1/2 cups mushrooms, sliced
• 2 tablespoons olive oil
• 1/4 teaspoon oregano
• 1/4 teaspoon dried parsley
• 1/4 teaspoon salt
• 1/4 cup water
• 1 1/2 cups fresh mozzarella cheese, chopped
• 1 1/4 cups parmesan cheese, freshly grated
• 16 lasagna noodles (also referred to as strips)

For the Sauce:

• 3 1/2 cups milk
• 1/4 cup butter
• 1/4 cup flour
• 1/4 teaspoon salt

Equipment Needed

• Small pot
• Small frying pan
• Medium frying pan
• Large pot
• Medium baking pan (approximately 12×10 inches)

Instructions

1. First, cook the peas. In a small pot of boiling water, add the frozen peas and cook until tender, about 10 minutes. Drain thoroughly.
2. Next, prepare the Italian sausage. In a small frying pan, cook the sausage over medium heat, adding 1/4 cup of water. Cook until the sausage is browned and thoroughly cooked, and the water has evaporated. Be careful not to let it burn. Set aside.
3. Now, prepare the mushrooms. In a medium frying pan, add 2 tablespoons of olive oil. Add the sliced mushrooms, 1/4 teaspoon of oregano, 1/4 teaspoon of dried parsley, 1/4 teaspoon of salt, and 1/4 cup of water. Cook on medium heat until the mushrooms are tender and the water has evaporated, stirring occasionally to prevent burning.
4. Once the mushrooms are cooked, add the drained peas and cooked Italian sausage to the frying pan. Combine well and set aside.
5. It’s time to make the white sauce (béchamel). In a large pot, melt 1/4 cup of butter over medium heat.
6. Whisk in 1/4 cup of flour and 1/4 teaspoon of salt. Cook for 1-2 minutes, stirring constantly, to create a roux. This will thicken the sauce.
7. Gradually stir in 3 1/2 cups of milk, whisking continuously to prevent lumps.
8. Cook and stir over medium heat until the mixture begins to bubble and thicken. This will take about 5-7 minutes.
9. Once the sauce has thickened, remove the pot from the heat.
10. Assemble the lasagna. In a medium baking pan (approximately 12×10 inches), spread a ladle of white sauce (about 1/2 cup) on the bottom of the pan. This prevents the noodles from sticking.
11. Begin layering. Place lasagna noodles (or strips) on top of the sauce. You will need approximately 4 noodles for each layer, breaking one in half lengthwise to fit the pan if necessary.
12. Add 1 1/2 to 2 ladles of white sauce (spread so that it covers the noodles).
13. Spread 1/4 of the sausage, mushroom, and pea mixture on top of the sauce.
14. Sprinkle 1/4 of the chopped fresh mozzarella cheese and 1/4 of the grated parmesan cheese over the mixture.
15. Repeat the layers – noodles, sauce, vegetable/sausage mixture, mozzarella, and parmesan – for a total of 4 layers.
16. Bake in a preheated 350°F (175°C) oven for approximately 20-25 minutes, or until the lasagna is golden brown and bubbly.
17. Let the lasagna sit for 5 minutes before cutting and serving. This allows the cheese to set slightly.

Expert Tips & Tricks

• For a richer flavor, use homemade Italian sausage.
• Don’t overcook the peas, as they will continue to cook in the lasagna.
• If the top of the lasagna is browning too quickly, cover it loosely with aluminum foil during the last 10 minutes of baking.
• The white sauce should be smooth and creamy. If you encounter lumps, you can use an immersion blender to smooth it out.
• Consider using no-boil lasagna noodles to save time. However, ensure they are well covered with sauce to prevent them from drying out.
• To ensure the lasagna is thoroughly heated, insert a knife into the center. If it comes out hot to the touch, it’s ready.
• A little nutmeg added to the white sauce offers extra depth of flavor.
