Vegan Lasagna Ingredients
• Gather ’round as we prepare to create this delicious Vegan French Onion Lasagna. Here’s what you’ll need!
For the Béchamel
- Vegan Butter or Olive Oil – Adds richness and helps caramelize onions. Use either; both provide flavor.
- Non-Dairy Milk (Oat Milk) – For ricotta and béchamel, providing creaminess. Almond milk or soy milk can be substituted.
- Fresh Thyme – Imparts herbal aroma to béchamel. Use ½ teaspoon of dried thyme as an alternative.
- Nutmeg – Adds warmth and depth to béchamel. Omit if unavailable; seasoning can be flexible based on taste.
For the Ricotta
- Extra Firm Tofu – Base for the ricotta, providing protein and texture. Silken tofu may create a smoother ricotta, but it will be less firm.
- Nutritional Yeast – Adds cheesy flavor to ricotta. Skip if using nutritional yeast-based cheese alternatives.
- Lemon Juice – Balances flavors in the ricotta. Vinegar can act as a substitute in a pinch.
For the Onions
- Sweet Onions – Main flavor component, caramelized for sweetness. Yellow onions can be a substitute.
- Agave Syrup – Enhances the sweetness of caramelized onions. Maple syrup can be used as an alternative.
For the Lasagna
- Vegan Mozzarella – Melts and adds creaminess to lasagna. Other dairy-free cheese options can work; use as per preference.
- Lasagna Sheets – The base of the dish. Regular or oven-ready sheets can be used.
Step‑by‑Step Instructions for Vegan French Onion Lasagna
Step 1: Caramelize the Onions
In a large skillet, melt 2 tablespoons of vegan butter or heat olive oil over medium heat. Add 3 sliced sweet onions, stirring occasionally for 25-30 minutes until they turn a rich golden brown. Near the end of cooking, drizzle in 1 tablespoon of agave syrup and a pinch of salt, allowing the onions to caramelize further. Their sweetness will be the heart of your Vegan French Onion Lasagna.
Step 2: Prepare the Ricotta
While the onions are caramelizing, blend 14 ounces of drained extra-firm tofu, 1/4 cup of nutritional yeast, and 2 tablespoons of lemon juice in a food processor. Gradually add 1/2 cup of non-dairy oat milk and blend until smooth and creamy. Taste the ricotta and adjust seasoning with salt as needed to ensure it’s flavorful, providing a delightful contrast to the caramelized onions.
Step 3: Create the Béchamel
In a medium saucepan, melt 2 tablespoons of vegan butter over medium heat. Whisk in 2 tablespoons of flour to form a roux, cooking for about 2-3 minutes until lightly golden. Gradually whisk in 2 cups of non-dairy milk, stirring constantly until the mixture thickens, this will take around 5-7 minutes. Finish by stirring in 1 teaspoon of fresh thyme, a pinch of nutmeg, and salt to taste, crafting a silky béchamel for your lasagna.
Step 4: Preheat the Oven
Preheat your oven to 375°F (190°C). This will ensure that your Vegan French Onion Lasagna bakes evenly and thoroughly, resulting in a bubbling, delicious centerpiece for any meal. While the oven is heating, gather your ingredients and set your workstation, making it easier to layer the lasagna.
Step 5: Layer the Lasagna
In a 9×13-inch baking dish, start by spreading a generous layer of the béchamel across the bottom. Place down your first layer of lasagna sheets, followed by half of the prepared ricotta, a layer of the caramelized onions, and a handful of vegan mozzarella. Repeat until you have filled the dish, finishing with a final layer of béchamel and a sprinkle of mozzarella on top, ensuring even coverage.
Step 6: Bake the Lasagna
Cover your baking dish with aluminum foil and place it in the preheated oven. Bake for 25-30 minutes or until hot and bubbly. Remove the foil during the last 10 minutes of baking to achieve a golden top. When finished, the Vegan French Onion Lasagna should be warm with a beautifully melted topping, making it an inviting dish to share.

Vegan French Onion Lasagna Recipe FAQs
How do I choose the right onions for the lasagna?
Absolutely! Sweet onions like Vidalia or Walla Walla are perfect as they caramelize beautifully, yielding a rich sweetness. If you can’t find sweet onions, yellow onions work well too; just be mindful they can be slightly sharper in flavor.
How should I store the leftovers?
For storage, place the leftover Vegan French Onion Lasagna in an airtight container and keep it in the fridge. It will stay fresh for up to 4 days. Make sure to let it cool completely before sealing to prevent moisture buildup.
Can I freeze Vegan French Onion Lasagna?
Yes, you can! For freezing, slice the lasagna into individual portions and wrap them tightly in plastic wrap before placing in an airtight container. It can stay frozen for up to 2 months. To reheat, thaw overnight in the fridge and warm in the oven at 350°F (175°C) for about 20-25 minutes.
Why is my ricotta too watery?
Very! If your ricotta ends up watery, it may be due to not pressing the tofu enough. Remember to wrap the tofu in a clean kitchen towel and place a weight (like a heavy pan) on top for at least 15-20 minutes. This helps remove excess moisture for a creamier consistency.
Are there any allergen considerations for this dish?
Certainly! This Vegan French Onion Lasagna is nut-free if you choose oat milk. However, be cautious with nutritional yeast, as some individuals may have sensitivities. To make it gluten-free, opt for gluten-free lasagna sheets. Always check package labels for allergens if you’re preparing for others.
