This Vegan Lasagna packs layers of creamy tofu ricotta, earthy lentils, and rich marinara into one bubbling, golden-topped casserole that makes you forget all about dairy. I first made this on a rainy Sunday when my friend Lily stopped by asking if I had anything hearty and plant-based, and honestly, I wasn’t sure tofu could pull off that silky ricotta vibe until we cut into it.
It’s surprisingly simple to put together, and if you’re looking for more cozy plant-based comfort, you’ll love this Easy Vegan Lentil Loaf Recipe or a fresh Best Santa Fe Salad Recipe on the side.
Why You’ll Love This Vegan Lasagna
It tastes like the real thing, but without any dairy or meat. The tofu ricotta gets whipped smooth and creamy with cannellini beans, so every bite feels indulgent. Lentils add texture and protein, while sun-dried tomatoes and mushrooms bring umami depth. It’s hearty enough for a crowd and holds together beautifully when you slice it.
You can make it ahead and just pop it in the oven when you’re ready. Leftovers actually taste better the next day when all the flavors marry together. Plus, it’s packed with fiber and plant protein, so you can feel good about going back for seconds.

Vegan Lasagna Ingredients
Here’s what you need to build this hearty, plant-based Vegan Lasagna from the bottom up.
See Recipe Card Below This Post For Ingredient Quantities
Lentil Layer:
Water: Cooks the lentils until they’re tender and ready to absorb all the savory flavors.
Dried brown lentils: These add protein, texture, and an earthy base that mimics ground meat. Rinse them well before cooking.
Salt: Seasons the lentils as they cook and balances the overall flavor throughout the dish.
Sun-dried tomatoes (in oil): Bring concentrated sweetness and umami richness. Save the oil for cooking.
Walnuts: Add a meaty texture and subtle nuttiness when chopped with the mushrooms.
White mushrooms: Release moisture as they cook, creating a savory, umami-packed base.
Reserved sun-dried tomato oil (or olive oil): Adds flavor to the mushroom mixture and prevents sticking.
Italian seasoning: A blend of herbs that brings classic Italian warmth to the lentil filling.
Petite diced tomatoes (in juices): Add moisture and fresh tomato flavor to the lentil mixture.
Vegan Lasagna:
Lasagna noodles: The foundation of every layer. Cook them al dente so they don’t get mushy when baked.
Olive oil: Keeps the noodles from sticking together after draining.
Marinara sauce (of your choice): Choose a good-quality sauce you love. It’s the backbone of this meatless lasagna.
Fresh spinach (tightly packed): Adds color, nutrition, and a slight earthy flavor between the creamy layers.
Fresh basil (minced): Brings bright, aromatic freshness to the top of the Vegan Lasagna.
Fresh parsley (minced): Adds a pop of color and a mild herby finish.
Tofu Ricotta:
Extra firm tofu: The base of the vegan ricotta. Drain it well before blending for the best texture.
Lemon juice: Adds tanginess that mimics the slight acidity of dairy ricotta.
Italian seasoning: Infuses the ricotta with herby, Italian flavor.
Cannellini beans (with liquid): Make the ricotta extra creamy and smooth. The liquid helps with blending.
Garlic cloves: Add a punch of savory flavor that balances the richness of the tofu.
Black pepper (freshly cracked): Brings a little heat and depth to the ricotta mixture.
How To Make Vegan Lasagna
Follow these steps to layer and bake your way to the best vegan comfort food.
Preheat oven: Set your oven to 375°F (190°C) so it’s ready when your lasagna is assembled.
Cook the lentils: In a medium saucepan, combine 3 cups of water, ½ cup lentils, and 1 teaspoon salt. Bring it to a boil, then reduce the heat and let it simmer for 15-20 minutes until the lentils are tender but still hold their shape. Strain and set them aside.
Prepare the sun-dried tomato and mushroom mixture: In a food processor, combine the sun-dried tomatoes, walnuts, and white mushrooms. Pulse until everything is finely chopped and looks like a minced texture.
Cook the noodles: Boil the lasagna noodles according to the package directions, usually 8-10 minutes, until they’re al dente. Drain them, toss with 1 teaspoon olive oil to prevent sticking, and cover them so they stay warm.
Cook the mushroom mixture: Heat 1 tablespoon of sun-dried tomato oil (or olive oil) in a large pan over medium-low heat. Add the mushroom mixture and cook, stirring occasionally, until the mushrooms release their moisture and then reabsorb it, about 10 minutes. You’ll notice the texture gets drier and more concentrated.
Prepare tofu ricotta: In a food processor, combine the strained tofu, lemon juice, 1 tablespoon Italian seasoning, cannellini beans with their liquid, garlic, and black pepper. Blend until the mixture is completely smooth and creamy, like real ricotta.
Combine the lentil mixture: Add 1 tablespoon Italian seasoning, the cooked lentils, and petite diced tomatoes to the pan with the mushroom mixture. Stir everything together and cook for 5 minutes to heat through and let the flavors blend.
Assemble the lasagna: Spread a thin layer of marinara sauce in the bottom of a 9×13-inch baking dish. Add a layer of lasagna noodles, overlapping them slightly. Spread half of the tofu ricotta mixture evenly over the noodles. Layer the fresh spinach on top of the ricotta. Add another layer of noodles. Spread a generous amount of sauce, then add the lentil mixture on top. Add another layer of noodles. Spread the remaining tofu ricotta over this layer. Add one more layer of noodles, then top with the remaining marinara sauce. Sprinkle the freshly minced parsley and basil over everything.
Bake the lasagna: Cover the baking dish with tinfoil and bake for 40 minutes. Remove the foil and bake for an additional 10 minutes to let the top brown and the edges get crispy.
Substitutions and Variations
You can swap ingredients based on what you have or your dietary needs.
Lentils: Use green lentils if you can’t find brown. Red lentils will get too mushy, so avoid those.
Tofu ricotta: If you’re not a fan of tofu, try cashew cream blended with nutritional yeast instead. It’ll be richer and nuttier.
Noodles: Use gluten-free lasagna noodles to make this dish completely gluten-free. Just follow the package directions since cook times vary.
Marinara sauce: Make your own if you have time, or use any store-bought variety you love. A garlic or basil-heavy sauce works great here.
Spinach: Swap with kale or Swiss chard if you want something heartier. Just chop it finely so it fits between the layers.
Mushrooms: Use baby bella or cremini mushrooms for a deeper, earthier flavor.
Equipment For Vegan Lasagna
Having the right tools makes assembly easier and faster.
9×13-inch baking dish: The standard size for Vegan Lasagna. Make sure it’s deep enough to hold all the layers.
Food processor: Blends the tofu ricotta smooth and chops the mushroom mixture evenly.
Large sauté pan: Cooks the mushroom and lentil mixture without crowding.
Medium saucepan: Boils the lentils to tender perfection.
Strainer: Drains the lentils and noodles quickly.
Storage and Reheating Tips
This plant-based Vegan Lasagna keeps well and tastes even better the next day.
Refrigerator: Store leftovers in an airtight container for up to 5 days. The flavors deepen as it sits.
Freezer: Wrap individual portions or the whole Vegan Lasagna tightly in plastic wrap, then foil. Freeze for up to 3 months. Thaw overnight in the fridge before reheating.
Reheating: Warm slices in the microwave for 2-3 minutes, or reheat in a 350°F oven covered with foil for 15-20 minutes. Add a splash of marinara on top if it looks dry.
Serving Suggestions
Pair this hearty vegan casserole with simple, fresh sides that balance the richness.
Serve it with a crisp green salad dressed in lemon vinaigrette. The acidity cuts through the creamy tofu ricotta beautifully. Garlic bread or warm focaccia on the side is always a hit for mopping up extra sauce.
If you want something lighter, try it alongside roasted vegetables like zucchini, bell peppers, or cherry tomatoes. A simple Easy Chicken Cacciatore Recipe makes a great pairing if you’re feeding both vegans and meat-eaters at the same table.
For a full Italian spread, add a glass of red wine and finish with fresh fruit or sorbet.
Expert Tips
These small tricks make a big difference in flavor and texture.
Drain your tofu well. Press it between paper towels or use a tofu press to remove excess moisture before blending. This keeps the ricotta from getting watery.
Don’t skip the mushroom step. Cooking the mushrooms until they release and reabsorb their moisture concentrates their flavor and prevents a soggy Vegan Lasagna.
Let it rest before slicing. After baking, let the Vegan Lasagna sit for 10-15 minutes. This helps the layers set so you get clean, beautiful slices instead of a saucy mess.
Use fresh herbs on top. The minced basil and parsley add brightness and a pop of color that makes the dish look as good as it tastes.
Make it ahead. Assemble the lasagna up to a day in advance, cover it tightly, and refrigerate. Just add 10 extra minutes to the bake time if you’re putting it in the oven cold.
FAQ
What is the correct order to layer Vegan Lasagna?
Start with sauce on the bottom of the dish, then noodles, tofu ricotta, spinach, noodles, sauce, lentil mixture, noodles, ricotta, noodles, and final sauce on top. This keeps everything moist and prevents sticking. My tip: always start and end with sauce to protect the noodles.
How to make a basic Vegan Lasagna?
Start with cooked lasagna noodles, a good marinara sauce, and a creamy vegan ricotta made from blended tofu or cashews. Layer them like traditional lasagna, adding vegetables or lentils for protein. Bake covered, then uncovered to brown the top. It’s easier than you think once you get the rhythm down.
Is Vegan Lasagna healthy, yes or no?
Yes, this version is packed with plant protein from lentils, tofu, and beans, plus fiber from vegetables and whole grains. It’s lower in saturated fat than traditional lasagna and has no cholesterol. Just watch your portion size since it’s still rich and filling.
What is the secret to a good Vegan Lasagna?
The secret is a creamy, well-seasoned tofu ricotta and a flavorful filling that mimics the richness of meat. Don’t skimp on seasoning, and let the lasagna rest after baking so the layers hold together. Using quality marinara sauce makes a huge difference too.
