Step-by-Step Instructions

Step 1: Cook the Lasagna Noodles

Boil lasagna noodles according to package instructions until al dente.

Drain and lay them flat on parchment paper to prevent sticking.

Tip: Add a little olive oil to the water to keep noodles from clumping.

Step 2: Sauté the Vegetables

Heat olive oil in a large skillet over medium heat.

Add:

onion
garlic

Cook for 2–3 minutes until fragrant.

Add mushrooms and cook for 5–6 minutes until softened.

Stir in spinach and cook until wilted.

Season with salt, pepper, and thyme.

Step 3: Prepare the Béchamel Sauce

In a saucepan melt butter over medium heat.

Whisk in flour and cook for 1 minute to form a roux.

Gradually add milk while whisking continuously.

Cook until the sauce thickens.

Add nutmeg and salt.

Pro Tip: Constant whisking prevents lumps and creates a smooth sauce.

Step 4: Assemble the Lasagna

In a baking dish layer:

A thin layer of béchamel sauce
Lasagna noodles
Mushroom-spinach mixture
Ricotta cheese
Mozzarella cheese

Repeat layers until ingredients are used.

Finish with béchamel and Parmesan on top.

Step 5: Bake the Lasagna

Preheat oven to 375°F (190°C).

Bake uncovered for 35–40 minutes until the top is golden and bubbly.

Step 6: Rest Before Serving

Let the lasagna rest for 10 minutes before slicing.

This helps the layers set and makes serving easier.
