Ingredients
For the Vegetable Filling:
- 2 tablespoons olive oil or butter
- 1 medium onion, finely chopped
- 3 garlic cloves, minced
- 2 cups mushrooms, sliced (button, cremini, or portobello)
- 4 cups fresh spinach (or 1 package frozen spinach, thawed and drained)
- ½ teaspoon dried thyme or Italian seasoning
- Salt and pepper, to taste
For the Béchamel Sauce:
- 4 tablespoons butter
- 4 tablespoons all-purpose flour
- 4 cups milk (whole or 2%, warm)
- ¼ teaspoon nutmeg (optional)
- Salt and pepper, to taste
For the Lasagna:
- 12 lasagna noodles (regular or no-boil)
- 2 cups shredded mozzarella cheese
- 1 cup grated Parmesan cheese
- 1 cup ricotta or cottage cheese (optional)
- Fresh parsley or basil, chopped (for garnish)
Instructions
1. Prepare the Vegetable Filling
- Heat olive oil or butter in a large skillet over medium heat.
- Add the onion and sauté until translucent, about 3–5 minutes.
- Stir in the garlic and mushrooms, cooking until the mushrooms release their liquid and are lightly browned, about 5–7 minutes.
- Add the spinach and cook until wilted (if using fresh) or heated through (if using frozen).
- Season with thyme, salt, and pepper. Remove from heat and set aside.
2. Make the Béchamel Sauce
- In a medium saucepan, melt the butter over medium heat.
- Stir in the flour and cook for 1–2 minutes, whisking constantly, to create a roux.
- Gradually add the warm milk while whisking to avoid lumps. Bring to a simmer and cook until thickened, about 5–7 minutes.
- Season with nutmeg (if using), salt, and pepper. Remove from heat.
3. Cook the Lasagna Noodles
- If using regular lasagna noodles, cook them in boiling salted water according to package instructions. Drain and lay flat on a clean surface.
- If using no-boil noodles, ensure the sauce is slightly thinner to compensate for the noodles absorbing moisture during baking.
4. Assemble the Lasagna
- Preheat your oven to 375°F (190°C).
- Spread a thin layer of béchamel sauce on the bottom of a 9x13-inch baking dish.
- Add a layer of lasagna noodles, followed by:
- A layer of the vegetable filling.
- A drizzle of béchamel sauce.
- A sprinkle of mozzarella and Parmesan cheese.
- Repeat layers until all ingredients are used, finishing with a layer of noodles, béchamel sauce, and cheese.
5. Bake the Lasagna
- Cover the baking dish with foil and bake for 25 minutes.
- Remove the foil and bake for an additional 15 minutes, or until the cheese is bubbly and golden brown.
- Let the lasagna rest for 10–15 minutes before slicing to allow the layers to set.
Serving Suggestions
- Garnish with fresh parsley or basil for added freshness.
- Serve with a crisp green salad and garlic bread for a complete meal.
Tips for Perfect Lasagna
- Make It Ahead: Lasagna tastes even better the next day. Assemble it in advance and refrigerate or freeze before baking.
- Use High-Quality Cheese: Freshly grated cheese melts better and enhances the flavor.
- Balance the Layers: Ensure each layer is evenly distributed for consistent flavor in every bite.
Variations
- Add Protein: Stir in cooked shredded chicken or crumbled tofu for a heartier dish.
- Vegan Option: Use plant-based milk, butter, and cheese for a dairy-free version.
- Gluten-Free: Use gluten-free lasagna noodles and a gluten-free flour blend for the béchamel sauce.
Storage and Reheating
- Refrigerate: Store leftovers in an airtight container for up to 3 days.
- Freeze: Wrap individual portions or the whole dish tightly in foil and freeze for up to 3 months.
- Reheat: Warm in the oven at 350°F (175°C) or in the microwave until heated through.
