Mushroom Lasagna Ingredients

For the Mushroom Filling
• Olive Oil – Adds richness and aids in sautéing; use vegetable oil if desired.
• Onions – Base flavor; cooking until translucent enhances sweetness.
• Garlic – Provides aromatic and pungent flavor; fresh or jarred minced garlic works well.
• Mushrooms (Cremini, Shiitake, Portobello) – Essential for umami flavor and texture; substitute with button or oyster mushrooms for different taste.
• Grape Tomatoes – Adds sweetness and freshness; cherry or sun-dried tomatoes can be good substitutes.
• Dried Thyme & Oregano – Seasoning for depth of flavor; swap for fresh herbs if available.
• White Wine – For deglazing and flavor; omit for a non-alcoholic version, or use vegetable broth instead.

For the Bechamel Sauce
• Butter – Base for the sauce; a vegan butter can be used for a dairy-free option.
• Flour – Thickens the Bechamel sauce; use gluten-free flour to make the dish gluten-free.
• Milk – Provides creaminess; plant-based milk is a great substitute for vegan versions.
• Nutmeg – Adds warmth and complexity to the sauce.

For the Lasagna Assembly
• Lasagna Noodles – Provides structural integrity; gluten-free noodles can be used for a gluten-free version.

Step‑by‑Step Instructions for Hearty Vegetarian Mushroom Lasagna with Grape Tomatoes

Step 1: Sauté the Aromatics
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add 1 finely chopped onion and sauté for about 5 minutes until it turns translucent and fragrant. This base will enhance the flavor of your Mushroom Lasagna. Stir occasionally to ensure even cooking and avoid burning.

Step 2: Add Garlic and Mushrooms
Incorporate 3 cloves of minced garlic into the skillet and cook for another minute until aromatic. Next, add 8 cups of sliced mushrooms (Cremini, Shiitake, or Portobello) and sauté for 8–10 minutes. Continue stirring until the mushrooms are browned and have released their moisture, bringing a rich umami flavor to your Mushroom Lasagna.

Step 3: Season the Mushroom Mixture
Sprinkle in 1 teaspoon of dried thyme and 1 teaspoon of dried oregano, along with salt and pepper to taste. Pour in ½ cup of white wine, stirring to deglaze the skillet. Cook for 2–3 minutes until the liquid is mostly evaporated, infusing the mushrooms with incredible depth of flavor before adding the grape tomatoes.

Step 4: Incorporate Grape Tomatoes
Stir in 2 cups of halved grape tomatoes to the skillet and cook for an additional 2–3 minutes until the tomatoes soften and release their juices. This step brightens the filling and adds delicious freshness to your Mushroom Lasagna. Once done, remove the skillet from heat and set aside.

Step 5: Prepare the Bechamel Sauce
In a medium saucepan, melt 4 tablespoons of butter over medium heat. Whisk in ¼ cup of all-purpose flour and cook for 2–3 minutes until golden and bubbling. This forms the base of your creamy Bechamel sauce, which brings a luscious element to your Mushroom Lasagna.

Step 6: Thicken the Bechamel
Gradually whisk in 3 cups of warmed milk, continuing to stir until the mixture thickens and bubbles, about 5–7 minutes. Season with a pinch of salt, pepper, and a dash of nutmeg for warmth and depth, perfectly complementing the Mushroom Lasagna’s flavors.

Step 7: Preheat the Oven and Cook Noodles
Preheat your oven to 375°F (190°C). Meanwhile, cook 10-12 lasagna noodles in boiling salted water according to package instructions until al dente, usually around 8–10 minutes. Drain and lay them on parchment paper to prevent sticking while you assemble the layers of your Mushroom Lasagna.

Step 8: Layer the Ingredients
In a 9×13 inch baking dish, spread a thin layer of Bechamel sauce on the bottom. Begin layering with lasagna noodles, then add half of your mushroom and tomato mixture, followed by a handful of fresh spinach and shredded mozzarella. Repeat this process, ensuring you end with a layer of noodles topped with Bechamel and a generous sprinkle of Parmesan cheese.

Step 9: Bake the Lasagna
Cover your assembled Mushroom Lasagna with aluminum foil and place it in the preheated oven. Bake for 25 minutes, allowing the flavors to meld beautifully. After 25 minutes, carefully remove the foil and bake for an additional 20 minutes until the top is golden and bubbly, creating an irresistible crust.

Step 10: Rest and Serve
Once out of the oven, allow the lasagna to rest for 10 minutes. This resting period helps the layers set, making it easier to cut. If desired, garnish with fresh basil before slicing. Your Hearty Vegetarian Mushroom Lasagna with Grape Tomatoes is now ready to serve and enjoy!

Make Ahead Options
