Step 1: Prepping the Vegetable Filling
The heart of this lasagna lies in its flavorful vegetable filling. The combination of earthy mushrooms, vibrant spinach, and aromatic garlic creates a foundation that’s both hearty and fresh. Here’s how to bring it all together:
- Heat It Up: Start by warming 2 tablespoons of olive oil in a large skillet over medium heat. The gentle sizzle of olive oil will soon signal the magic to come.
- Sauté the Mushrooms: Add 2 cups of sliced mushrooms to the pan. Stir them around, letting them cook until they’re golden and tender—about 5 minutes. This step not only deepens their flavor but also releases their natural juices.
- Wilt the Spinach: Toss in 3 cups of roughly chopped fresh spinach and 3 minced garlic cloves. As the spinach wilts and the garlic aroma fills your kitchen, season everything with a generous pinch of salt and pepper.
- Set Aside: Once cooked, remove the skillet from the heat and let the filling cool slightly. Trust me, you’ll want to sneak a taste—it’s irresistible!

Step 2: Crafting the Perfect Béchamel Sauce
Now that the veggies are prepped, it’s time to whip up a luxurious béchamel sauce. This creamy white sauce is what elevates this lasagna into something truly special.
- Start the Roux: In a medium saucepan, melt 3 tablespoons of butter over medium heat. Once melted, stir in 3 tablespoons of all-purpose flour to create a smooth paste. Cook this mixture for 1-2 minutes, stirring constantly. This step ensures your sauce won’t taste floury.
- Add Milk Gradually: Slowly pour in 3 cups of warm milk, whisking continuously to avoid lumps. As the mixture heats, it will begin to thicken.
- Season to Perfection: Once the sauce has a smooth, creamy consistency, stir in ½ teaspoon of ground nutmeg, along with a pinch of salt and pepper. Remove it from the heat, and voilà—you’ve got a béchamel sauce that’s silky, flavorful, and ready to shine in your lasagna.
