How to Make Mushroom and Spinach Lasagna (Step-by-Step)
1. Prepare the Mushroom and Spinach Filling
Heat olive oil in a large skillet over medium heat. Add chopped onions and cook for 3–4 minutes until translucent. Add garlic and cook for another minute. Toss in the mushrooms, season with salt, pepper, and herbs, and cook until they release their moisture and turn golden brown (about 10 minutes). Finally, stir in the spinach and cook until wilted. Set aside.
🔥 Pro Tip: Make sure all the moisture is cooked out of the spinach and mushrooms to avoid a soggy lasagna.
2. Make the Creamy Béchamel Sauce
In a saucepan, melt butter over medium heat. Whisk in flour to form a roux, and cook for 1–2 minutes. Slowly add milk while whisking continuously to prevent lumps. Bring to a gentle simmer, stir in nutmeg, and season with salt and pepper. Cook until thickened (about 5–7 minutes).
3. Assemble the Lasagna
Preheat oven to 375°F (190°C).
In a 9×13 inch baking dish, spread a thin layer of béchamel sauce. Layer noodles over it, followed by half the mushroom-spinach filling, a few dollops of ricotta, some béchamel sauce, and a sprinkle of mozzarella. Repeat layers, finishing with a top layer of noodles, béchamel, mozzarella, and Parmesan cheese.
4. Bake and Serve
Cover the lasagna with foil and bake for 25 minutes. Remove the foil and bake an additional 15–20 minutes until the top is golden and bubbling. Let it rest for 10 minutes before slicing.
🍽️ Serving Suggestion: Pair your Mushroom and Spinach Lasagna with a side salad and garlic bread for a complete Italian-inspired meal.
