Lasagna noodles
Olive oil

Onion, diced
Butter
All-purpose flour
Milk
Heavy cream
Ricotta cheese
Mozzarella cheese, shredded
Parmesan cheese, grated
Salt
Black pepper
Italian seasoning
Fresh parsley for garnish

Directions

I preheat the oven to 375°F (190°C).

I cook the lasagna noodles according to the package instructions and set them aside.

I heat olive oil in a large skillet and sauté the onions until softened.

I add the mushrooms and cook until they release their moisture and become lightly golden.

I stir in the garlic and spinach, cooking until the spinach wilts.

I season the vegetable mixture with salt, pepper, and Italian seasoning.

I prepare the creamy sauce by melting butter in a saucepan and whisking in the flour until smooth.

I gradually add the milk and heavy cream, whisking continuously until the sauce thickens.

I stir in a portion of the Parmesan cheese and season to taste.

I spread a thin layer of sauce in the bottom of a baking dish.

I arrange a layer of lasagna noodles over the sauce.

I add some of the spinach and mushroom mixture, followed by dollops of ricotta cheese, sauce, and mozzarella.

I repeat the layers until all ingredients are used, finishing with sauce, mozzarella, and the remaining Parmesan cheese.

I cover the dish with foil and bake for 30 minutes.

I remove the foil and bake for an additional 15 to 20 minutes until bubbly and golden.

I let the lasagna rest for about 15 minutes before slicing and serving.

Variations

I sometimes add roasted zucchini for extra vegetables and flavor.

I like mixing a little fontina or provolone cheese with the mozzarella for a richer taste.

I occasionally include red pepper flakes for a gentle kick of heat.

I can substitute kale for spinach when I want a heartier texture.

I enjoy adding fresh herbs such as basil or thyme for additional freshness.

Storage/Reheating

I store leftover lasagna in an airtight container in the refrigerator for up to 4 days.

I cover individual portions and reheat them in the microwave until warmed through.

For larger portions, I reheat the lasagna in a 350°F (175°C) oven until hot.

I can freeze the baked lasagna for up to 3 months and thaw it overnight in the refrigerator before reheating.
