Spinach Mushroom Lasagna this Recipe

Ingredients:

  • For the Spinach Mushroom Filling:
    • 2 tablespoons olive oil
    • 1 large onion, chopped
    • 2 cloves garlic, minced
    • 1 pound cremini mushrooms, sliced
    • 10 ounces fresh spinach, roughly chopped
    • 1/2 cup ricotta cheese
    • 1/4 cup grated Parmesan cheese
    • 1 large egg, lightly beaten
    • 1/4 teaspoon ground nutmeg
    • Salt and freshly ground black pepper to taste
  • For the Béchamel Sauce:
    • 4 tablespoons unsalted butter
    • 4 tablespoons all-purpose flour
    • 4 cups milk, warmed
    • 1/4 teaspoon ground nutmeg
    • Salt and freshly ground white pepper to taste
  • For the Lasagna Assembly:
    • 9 lasagna noodles, oven-ready (no-boil)
    • 1 1/2 cups shredded mozzarella cheese
    • 1/2 cup grated Parmesan cheese, for topping

Preparing the Spinach Mushroom Filling

  1. Sauté the Aromatics: Heat the olive oil in a large skillet over medium heat. Add the chopped onion and cook until softened and translucent, about 5-7 minutes. Add the minced garlic and cook for another minute until fragrant, being careful not to burn it. Burnt garlic can ruin the whole dish!
  2. Cook the Mushrooms: Add the sliced mushrooms to the skillet and cook until they release their moisture and become tender, about 8-10 minutes. Stir occasionally to ensure even cooking. You want them to be nicely browned for maximum flavor.
  3. Wilt the Spinach: Add the roughly chopped spinach to the skillet. Cook until the spinach wilts down significantly, about 2-3 minutes. Stir frequently to ensure even wilting. Don’t overcook the spinach, as it will become mushy.
  4. Combine and Season: Remove the skillet from the heat and let the mixture cool slightly. In a large bowl, combine the cooked spinach and mushroom mixture with the ricotta cheese, 1/4 cup of Parmesan cheese, and the lightly beaten egg. Season with nutmeg, salt, and pepper to taste. Be generous with the seasoning, as this is the heart of the lasagna! Taste and adjust as needed.

Making the Béchamel Sauce

  1. Melt the Butter: In a medium saucepan, melt the unsalted butter over medium heat. Make sure the butter doesn’t brown.
  2. Create the Roux: Add the all-purpose flour to the melted butter and whisk constantly until a smooth paste forms. This is called a roux. Cook the roux for about 1-2 minutes, stirring constantly, to cook out the raw flour taste. The roux should be pale and slightly bubbly.
  3. Add the Milk Gradually: Gradually pour in the warmed milk, about 1/2 cup at a time, whisking constantly to prevent lumps from forming. Make sure each addition of milk is fully incorporated before adding more. This is crucial for a smooth sauce.
  4. Simmer and Thicken: Continue to cook the sauce over medium-low heat, stirring constantly, until it thickens to a nappe consistency (it should coat the back of a spoon), about 8-10 minutes. Be patient and keep stirring!
  5. Season the Sauce: Remove the saucepan from the heat and season the béchamel sauce with nutmeg, salt, and white pepper to taste. White pepper is preferred for its subtle flavor and to avoid dark specks in the sauce. Taste and adjust the seasoning as needed.

Assembling the Lasagna

  1. Preheat the Oven: Preheat your oven to 375°F (190°C).
  2. Prepare the Baking Dish: Lightly grease a 9×13 inch baking dish.
  3. Layer 1: Sauce and Noodles: Spread a thin layer of béchamel sauce on the bottom of the baking dish. This will prevent the noodles from sticking. Arrange three lasagna noodles over the sauce, overlapping slightly if necessary.
  4. Layer 2: Spinach Mushroom Filling and Cheese: Spread half of the spinach mushroom filling evenly over the noodles. Sprinkle with 1/2 cup of shredded mozzarella cheese.
  5. Layer 3: Sauce and Noodles: Spread another layer of béchamel sauce over the mozzarella cheese. Arrange three more lasagna noodles over the sauce, overlapping slightly if necessary.
  6. Layer 4: Spinach Mushroom Filling and Cheese: Spread the remaining spinach mushroom filling evenly over the noodles. Sprinkle with another 1/2 cup of shredded mozzarella cheese.
  7. Layer 5: Sauce and Noodles: Spread the remaining béchamel sauce evenly over the mozzarella cheese. Arrange the final three lasagna noodles over the sauce, overlapping slightly if necessary.
  8. Top with Cheese: Sprinkle the remaining 1/2 cup of shredded mozzarella cheese and 1/2 cup of grated Parmesan cheese evenly over the top layer of noodles. This will create a beautiful golden-brown crust.
  9. Bake: Cover the baking dish with aluminum foil and bake for 30 minutes.
  10. Uncover and Bake Again: Remove the aluminum foil and bake for another 15-20 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Keep a close eye on it to prevent burning.
  11. Rest: Remove the lasagna from the oven and let it rest for at least 15-20 minutes before cutting and serving. This allows the lasagna to set and makes it easier to slice. Trust me, this step is important!

Tips for the Best Spinach Mushroom Lasagna

  • Don’t Overcook the Noodles: Even though you’re using no-boil noodles, they can still become mushy if overcooked. Make sure there’s enough sauce to hydrate them properly.
  • Use Fresh Spinach: Fresh spinach has a better flavor and texture than frozen spinach. If you must use frozen, be sure to thaw it completely and squeeze out all the excess moisture.
  • Quality Cheese Matters: Use good quality mozzarella and Parmesan cheese for the best flavor. Freshly grated Parmesan is always preferable.
  • Make Ahead: This lasagna can be assembled ahead of time and stored in the refrigerator for up to 24 hours before baking. Just add a few extra minutes to the baking time.
  • Freezing Instructions: You can also freeze the assembled lasagna before baking. Wrap it tightly in plastic wrap and then in aluminum foil. It can be stored in the freezer for up to 3 months. Thaw it in the refrigerator overnight before baking.
  • Variations: Feel free to add other vegetables to the filling, such as bell peppers, zucchini, or eggplant. You can also use different types of cheese, such as provolone or fontina.
  • Spice it Up: Add a pinch of red pepper flakes to the spinach mushroom filling for a little heat.
  • Herb it Up: Fresh herbs like basil, oregano, or thyme can add a lot of flavor to the lasagna. Add them to the spinach mushroom filling or sprinkle them on top before baking.
Serving Suggestions

This Spinach Mushroom Lasagna is delicious on its own, but it also pairs well with a variety of side dishes. Here are a few suggestions:

  • Garlic Bread: A classic pairing for lasagna.
  • Side Salad: A simple green salad with a vinaigrette dressing.
  • Roasted Vegetables: Roasted asparagus, broccoli, or Brussels sprouts.
  • Caprese Salad: Sliced tomatoes, mozzarella, and basil with a balsamic glaze.
