Ingredients
Method
- Bring a large pot of salted water to a rolling boil. Add the spinach and cook for 2–3 minutes, stirring occasionally to ensure even cooking. Drain thoroughly in a fine-mesh sieve, then squeeze out excess water. Chop finely and set aside.
- Meanwhile, melt 1 tablespoon butter in a large skillet over medium-high heat. Add shallots and garlic, stirring for 1 minute until fragrant. Add mushrooms, ¼ teaspoon salt, and ¼ teaspoon pepper. Cook, stirring, until mushrooms release their liquid, about 5 minutes. Remove from heat and allow to cool.
- In a medium saucepan, melt the remaining 5 tablespoon butter over medium heat. Sprinkle in the flour and whisk continuously for 2 minutes to cook the flour. Gradually pour in the milk while whisking constantly. Bring to a simmer, whisking until thickened. Stir in ½ teaspoon salt, ¼ teaspoon pepper, nutmeg, and 1 cup Parmesan, stirring for 2 minutes until creamy. Remove from heat.
- In a medium bowl, combine ricotta and mozzarella with ¼ cup of the prepared sauce until evenly mixed.
- Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with cooking spray. Spoon ½ cup of sauce onto the bottom.
- Divide mushrooms and spinach into four portions. Sprinkle 1 portion of mushrooms and spinach over the sauce, then layer 4 noodles side by side.
- Spread slightly less than ½ cup of sauce over noodles. Top with ¼ of mushrooms and spinach, ⅓ of the ricotta mixture, and 6 provolone slices.
- Repeat the layering process twice more, finishing with a final layer of noodles. Cover noodles with the remaining sauce and sprinkle with the remaining 1 ¾ cups Parmesan.
- Cover tightly with aluminum foil. Bake for 30 minutes, then remove foil and bake an additional 10–15 minutes until bubbly and golden. Optionally broil for 1 minute to crisp the top.
- Allow lasagna to rest for 10–15 minutes before slicing and serving hot.
