Instructions

1. Cook the Lasagna Noodles

Bring a large pot of salted water to a boil. Cook lasagna noodles according to package instructions. Drain and set aside.

2. Prepare the Spinach

Heat olive oil in a skillet over medium heat. Add garlic and sauté for about 30 seconds. Add chopped spinach and cook until wilted. Season lightly with salt and pepper.

3. Make the White Sauce

In a saucepan, melt butter over medium heat. Whisk in flour and cook for about 1 minute to form a roux.

4. Add Milk

Slowly whisk in the milk, stirring constantly to prevent lumps. Continue cooking until the sauce thickens.

5. Season the Sauce

Add salt, nutmeg, and parmesan cheese. Stir until the cheese melts and the sauce becomes smooth and creamy.

6. Preheat the Oven

Preheat your oven to 375°F (190°C) and lightly grease a baking dish.

7. Begin Layering the Lasagna

Spread a thin layer of white sauce on the bottom of the dish. Add a layer of lasagna noodles.

8. Add the Filling

Spread ricotta cheese, sautéed spinach, and a drizzle of pesto over the noodles.

9. Add Cheese

Sprinkle mozzarella over the filling.

10. Repeat Layers

Continue layering noodles, white sauce, pesto, spinach mixture, and cheese until all ingredients are used.

11. Finish the Top Layer

Top with remaining white sauce, mozzarella, and parmesan.

12. Bake the Lasagna

Bake for 30–35 minutes until the cheese is melted and bubbly.

13. Let It Rest

Allow the lasagna to rest for about 10 minutes before slicing. This helps the layers set.

14. Serve

Slice and serve warm with fresh basil or extra parmesan.

Tips for Perfect Pesto Lasagna

Use Quality Pesto

Fresh homemade pesto provides the best flavor, but good store-bought pesto works well too.

Drain Spinach Well

Excess moisture can make the lasagna watery, so squeeze out extra liquid.

Let Lasagna Rest

Resting helps the layers firm up so slices hold their shape.

Don’t Skip the Nutmeg

A tiny pinch enhances the flavor of the white sauce beautifully.

Variations You Can Try

Add Mushrooms

• Grilled chicken
• Italian sausage
• White beans

Experiment with cheeses like:

• Fontina
• Gruyère
• Provolone
