How to Make Vegetarian White Sauce Lasagna

This creamy, cheesy, and vegetable-packed lasagna comes together easily with just a few steps. Follow this simple method for a perfectly layered, rich, and flavorful dish every time!

Prepare the White Sauce

Melt the butter. In a medium saucepan over medium heat, melt the butter until fully liquid.

Whisk in the flour. Add the flour and whisk continuously for about 1 minute, allowing it to cook slightly and remove any raw taste.

Add the milk gradually. Slowly pour in the milk, whisking constantly to prevent lumps. Let it simmer for 4-5 minutes, stirring frequently, until it thickens into a smooth, velvety sauce.

Season the sauce. Stir in the salt, black pepper, garlic powder, and nutmeg for flavor. Then, mix in the Parmesan cheese, allowing it to melt into the sauce. Remove from heat and set aside.

Prepare the Vegetable Filling

Sauté the aromatics. Heat olive oil in a large skillet over medium heat. Add the onion and garlic, sautéing until fragrant and softened.

Cook the vegetables. Stir in the mushrooms, zucchini, and bell pepper, cooking for about 5 minutes until tender.

Add the greens and seasoning. Toss in the spinach, oregano, and basil, cooking for another 1-2 minutes until the spinach wilts. Season with salt and pepper to taste. Remove from heat.

Assemble the Lasagna

Preheat the oven. Set your oven to 375°F (190°C) and lightly grease a 9×13-inch baking dish.

Layer the ingredients.

• Spread a thin layer of white sauce at the bottom of the dish.
• Place 3 cooked lasagna noodles on top.
• Spread ⅓ of the ricotta cheese, followed by ⅓ of the vegetable mixture.
• Drizzle with more white sauce, then sprinkle mozzarella and Parmesan cheese.
• Repeat the layers two more times, finishing with a generous topping of white sauce and cheese.

Bake the Lasagna

Cover and bake. Cover the dish loosely with foil and bake for 30 minutes.

Uncover and broil. Remove the foil and bake for an additional 10-15 minutes until the cheese on top is golden and bubbly.

Rest before serving. Let the lasagna sit for 10 minutes before slicing—this helps the layers set for easier cutting.

Garnish and Serve

Sprinkle with fresh basil or parsley and serve warm. Pair with a crisp side salad or garlic bread for a complete meal!

This Vegetarian White Sauce Lasagna is creamy, comforting, and bursting with flavor—perfect for a cozy weeknight dinner or special occasion!

Tips and Notes

To make your Vegetarian White Sauce Lasagna absolutely foolproof, here are some expert tips and tricks to ensure the best texture, flavor, and consistency every time.

Cooking Tips

Use oven-ready lasagna noodles. This saves time by skipping the boiling step, and they will cook perfectly in the sauce while baking.

Whisk the white sauce continuously. This prevents lumps and ensures a smooth, creamy béchamel with the perfect texture.

Let the lasagna rest before slicing. Allowing it to sit for 10-15 minutes after baking helps the layers set, making it easier to cut into clean slices.

Ingredient Substitutions

Make it gluten-free. Use gluten-free lasagna noodles and replace the all-purpose flour in the white sauce with gluten-free flour or cornstarch.

Dairy-free alternative. Swap regular milk for unsweetened almond milk or oat milk, use vegan butter, and replace cheese with dairy-free cheese alternatives.

Protein boost. Add cooked lentils or crumbled tofu to the vegetable mixture for extra protein without compromising the vegetarian base.

Storage and Make-Ahead Tips

Make ahead for convenience. Assemble the lasagna up to a day in advance, cover it tightly, and refrigerate until ready to bake.

How to store leftovers. Keep leftovers in an airtight container in the refrigerator for up to 4 days.

Reheat with care. Warm individual slices in the microwave for 1-2 minutes, or reheat the entire dish in the oven at 350°F (175°C) for 15-20 minutes until heated through.

Freezing instructions. Wrap the unbaked lasagna tightly in plastic wrap and aluminum foil, then freeze for up to 3 months. When ready to bake, thaw overnight in the refrigerator and bake as directed.

Advanced Tips for Flavor

Roast the vegetables. For extra depth of flavor, roast the zucchini, mushrooms, and bell peppers before layering them into the lasagna.

Add a hint of lemon zest. A sprinkle of fresh lemon zest in the white sauce brightens the flavors and complements the richness.

Pro Tip: For an extra crispy cheese topping, broil the lasagna for 2-3 minutes at the end of baking until golden and bubbly.

With these tips, your Vegetarian White Sauce Lasagna will turn out perfectly creamy, flavorful, and delicious every time!

• Use gluten-free lasagna noodles for an easy gluten-free adaptation without changing the flavor.
