There’s something about a gooey, cheesy vegan lasagna that feels like a warm hug after a long day. It’s a dish that taps into nostalgia, reminding me of family dinners and Sunday gatherings, but without any dairy or meat. I love how simple ingredients can come together into something rich, satisfying, and totally plant-based.
This recipe is my go-to when I want comfort food that doesn’t leave me feeling heavy or sluggish. It’s a forgiving dish, too—layers of tender pasta, flavorful tomato sauce, and a velvety cashew cheese that melts just right. Making it from scratch means I can tweak it to my taste, adding a little extra smoky paprika or fresh basil when I want that extra punch of flavor.
Focusing on how this vegan lasagna can serve as a comfort meal for those missing traditional cheesy dishes, emphasizing the rich, gooey, nostalgic qualities that make it feel indulgent despite being plant-based.
The inspiration behind this dish
- I first made this vegan lasagna after a long weekend of experimenting with dairy-free cheeses and layered sauces. Sitting down with a slice, I realized how much I missed the gooey, cheesy comfort of traditional lasagna—without the heaviness. It was a small victory, figuring out how to get that melt and stretch with cashews and nutritional yeast.
- This dish came from a need to satisfy that nostalgic craving while keeping it plant-based and approachable. It’s become a staple for dinner parties and cozy weekends, reminding me that comfort food doesn’t have to come from animal products. Plus, the smell of garlic and tomato bubbling in the oven is just irresistible—like a warm invitation to linger at the table.

Key Ingredients and Tips
- Cashews: I love how they turn silky and cheesy when blitzed—just soak them first to get that creamy texture. Feel free to swap for peeled almonds for a nuttier taste.
- Tomato sauce: I aim for a rich, thick sauce with a splash of red wine and herbs. If yours is too tangy, a pinch of sugar balances it out without losing that vibrant tomato brightness.
- Lasagna noodles: I prefer to use no-boil noodles for convenience, but if you go for regular, make sure they’re al dente—overcooked noodles turn mushy and lose their structure.
- Nutritional yeast: It gives that cheesy, umami kick. If you’re out, try a dash of smoked paprika and lemon zest for a similar depth, but it won’t replicate that nutty flavor exactly.
- Vegetables: Sauté mushrooms, spinach, and zucchini until just tender—watch for their aroma turning earthy and fragrant. Use fresh herbs to brighten the layers, or go wild with kale if you like some bitterness.
- Plant-based cheese: I swear by store-bought vegan mozzarella—melts nicely and stretches just like traditional cheese. To make it more decadent, sprinkle some extra nutritional yeast on top before baking.
- Olive oil: I use a good extra virgin for sautéing—feels rich and fragrant. Skip if you prefer a lighter touch; just keep an eye on your veggies to prevent burning and bitterness.

Step-by-step guide to vegan lasagna
- Gather all your equipment: a large ovenproof baking dish, a saucepan, a blender, and a sharp knife. Preheat your oven to 180°C (350°F).
- Prepare the vegan cheese: soak 1 cup of cashews in hot water for 15 minutes. Drain and blend with nutritional yeast, lemon juice, garlic, salt, and water until smooth. Set aside.
- Make the tomato sauce: in a saucepan, heat 2 tbsp olive oil over medium heat. Add chopped onion and minced garlic, sauté until fragrant, about 2-3 minutes. Stir in crushed tomatoes, basil, oregano, salt, and pepper. Simmer on low for 20 minutes, stirring occasionally. The sauce should thicken slightly and smell rich and herbal.
- Cook the veggies: in a skillet, heat 1 tbsp olive oil. Sauté sliced mushrooms, zucchini, and spinach until just tender, about 5 minutes. Season with a pinch of salt and pepper. The vegetables should be fragrant and slightly caramelized.
- Assemble the lasagna: spread a thin layer of tomato sauce at the bottom of your baking dish. Lay down a layer of no-boil lasagna noodles, slightly overlapping. Spread a layer of cashew cheese, then a handful of sautéed veggies. Repeat the layers, ending with a top layer of noodles covered with tomato sauce and a sprinkle of vegan mozzarella.
- Bake uncovered: place the assembled lasagna in the oven for 40-45 minutes. The top should be bubbling, golden, and smelling smoky with hints of garlic and herbs. If the cheese starts to brown too quickly, loosely cover with foil.
- Rest and serve: let the lasagna sit for at least 15 minutes after baking. This allows the layers to set and makes slicing easier. Garnish with fresh basil or oregano before serving.
Let the lasagna rest for 15 minutes to set the layers. Slice with a sharp knife, serve warm, and garnish with fresh herbs.

Method
- Drain the soaked cashews and place them into a blender along with nutritional yeast, lemon juice, minced garlic, a pinch of salt, and water. Blend until smooth and creamy, adjusting with more water if needed to reach a velvety consistency. Set aside.
- Heat olive oil in a saucepan over medium heat. Add chopped onion and sauté until translucent and fragrant, about 3 minutes. Stir in crushed tomatoes, salt, pepper, and a handful of fresh basil if desired. Let simmer gently for 20 minutes until the sauce thickens and develops rich aroma.
- While the sauce simmers, sauté your chosen vegetables—mushrooms, zucchini, and spinach—in a skillet with a splash of olive oil until just tender and fragrant, about 5 minutes. Season lightly with salt and pepper. Remove from heat and set aside.
- Spread a thin layer of tomato sauce at the bottom of your ovenproof baking dish. Place a layer of no-boil lasagna noodles over the sauce, slightly overlapping. Spread a layer of cashew cheese evenly over the noodles, then sprinkle with sautéed vegetables and a handful of shredded vegan mozzarella.
- Repeat the layering process—noodles, cashew cheese, vegetables, cheese—until all ingredients are used, ending with a top layer of noodles covered with tomato sauce and a generous sprinkle of vegan mozzarella.
- Bake the assembled lasagna in a preheated oven at 180°C (350°F) for 40–45 minutes, until bubbling around the edges and the top is golden brown. If the cheese begins to brown too quickly, tent the dish with foil to protect it.
- Remove the lasagna from the oven and let it rest for at least 15 minutes. This helps the layers set and makes slicing easier. Garnish with fresh basil or herbs if desired.

Common mistakes and how to fix them
- FORGOT to soak cashews → Soak for at least 15 minutes for creaminess.
- DUMPED sauce too early → Let it simmer until thick and fragrant.
- OVER-TORCHED top → Cover with foil if cheese browns too quickly.
- MISSED layer balance → Keep layers even for consistent texture.
Quick fixes and pantry swaps
- When sauce is too thick, splash in warm water and stir until smooth.
- If lasagna edges stick, line the dish with parchment paper before baking.
- Splash a little olive oil on top if cheese isn’t melting evenly.
- Patch over cracked noodles with extra sauce—keeps layers moist and flavorful.
- Shield bubbling cheese with foil if it shimmers too quickly, avoiding burnt spots.
Prepping, storing, and reheating tips
- Assemble the lasagna a day in advance; keep it covered in the fridge for up to 24 hours. The flavors meld overnight, and the cheese sets a bit more, making slicing easier.
- Store leftovers in an airtight container in the fridge for 3–4 days. Expect the lasagna to be slightly drier but still flavorful, with the cheese firming up.
- Freeze individual portions or the entire dish for up to 2 months. Wrap tightly in plastic wrap and foil to prevent freezer burn. Thaw overnight in the fridge before reheating.
- Reheat in the oven at 180°C (350°F) for 20–25 minutes, covered initially. The top should bubble gently, and the aroma of garlic and herbs will refresh. For quicker reheats, microwave in 1-minute bursts, checking for even warmth and a creamy texture.
