The beauty of this Vegan White Lasagna with Cashew Ricotta, Spinach, and Peas Recipe lies in its straightforward, wholesome ingredients.

The simplicity of these ingredients allows the flavors to shine while creating a luscious, comforting dish.

Quick Tip

All ingredient amounts are listed in the recipe card below

Raw cashews: These are the secret to the creamy alfredo and ricotta textures without any dairy.
Veggie broth: Adds richness and depth to the alfredo sauce base.
Cornstarch: Helps thicken the alfredo sauce to a luscious consistency.
Black pepper & red pepper flakes: Provide a subtle spice kick that livens up the dish.
Olive oil: Used for both the ricotta and greasing the baking dish to add richness and help with texture.
No-boil lasagna noodles: Make assembly quick and mean no pre-cooking, creating perfect layers every time.
Frozen spinach and peas: Convenient, colorful, and full of vitamins for a vibrant filling.
Nutritional yeast: Sprinkled on top for a cheesy finish without any dairy.
Extra-firm tofu: Blended into the ricotta for creaminess and a protein boost.
Garlic cloves, lemon juice, Italian seasoning, basil, salt, and pepper: The aromatics and seasonings bring that classic Italian flavor and brighten every bite.

Directions

Step 1: Start by making the alfredo sauce. Add the raw cashews and vegetable broth to a blender, and blend for about one minute until completely smooth. Then, sprinkle in black pepper and, if you like a little heat, crushed red pepper flakes, and pulse briefly to mix.

Step 2: Pour the blended sauce into a small saucepan and place it over medium heat. Slowly whisk in the cornstarch and continue stirring for about 5 minutes as it thickens beautifully. Once thickened, take it off the heat and set aside.

Step 3: Next up is the tofu ricotta. Place the cashews, olive oil, water, whole garlic cloves, extra-firm tofu, lemon juice, Italian seasoning, red pepper flakes, fresh basil, salt, and black pepper into a food processor. Blend until silky smooth. Taste it and adjust the seasoning as you please. Set it aside for assembly.

Step 4: Grease the bottom and sides of a deep 9x13-inch baking dish generously with olive oil. Pour one cup of water into the dish to help hydrate the noodles as they cook.

Step 5: Lay down the first even layer of no-boil lasagna noodles over the water in your baking dish. Then spread one-third of your tofu ricotta over them. Add one bag of thawed and well-drained spinach evenly on top, along with half the peas. Pour over one cup of the creamy alfredo sauce.

Step 6: Repeat the layers: noodles, ricotta, the remaining bag of spinach, rest of the peas, and another cup of alfredo sauce.

Step 7: Add one final layer of noodles. Spread all remaining tofu ricotta on top, then pour over all remaining alfredo sauce. Finish by sprinkling the nutritional yeast evenly over the surface for a golden, cheesy touch.

Step 8: Cover the baking dish tightly with aluminum foil. This step helps the noodles hydrate and steam, ensuring tender layers. Let it rest while you preheat your oven to 350 degrees Fahrenheit.

Step 9: Bake covered for 45 minutes. Then carefully remove the foil and check the lasagna. If the top looks dry, splash a little water around the edges to keep it moist.

Step 10: Bake uncovered for an additional 10 to 15 minutes, allowing the top to develop a lightly browned, irresistible crust. Let it sit for 10 to 15 minutes after baking before slicing to let everything set perfectly.

Servings and Timing

This Vegan White Lasagna with Cashew Ricotta, Spinach, and Peas Recipe serves 6 generous portions, making it perfect for a family dinner or sharing with friends. Prep time is around 15 minutes, which includes making the sauces and assembling the layers. The total baking time is about 1 hour, comprised of 45 minutes covered baking and 10 to 15 minutes uncovered for that golden finish. Including resting time, plan for about 1 hour and 15 minutes from start to finish. The waiting is so worth it!

How to Serve This Vegan White Lasagna with Cashew Ricotta, Spinach, and Peas Recipe

The dish shows four long layers of golden-brown baked pasta sheets with a slightly rough texture, laid side by side in a white baking dish. Underneath the pasta sheets, a creamy white sauce mixed with visible green spinach leaves creates a thick base layer. The edges of the pasta have a wavy, slightly curled pattern, and the top surface has a crisp, browned finish. The scene is set on a white marbled surface with a white cloth and a white plate with two silver forks on the side. photo taken with an iphone --ar 4:5 --v 7

I love serving this creamy white lasagna with a simple yet crisp side salad—something with a lemony vinaigrette to balance the richness. Roasted vegetables like asparagus or a medley of root veggies work beautifully if you want something warm on the side. Fresh, crunchy bread is always a winner to scoop up any leftovers on the plate.

When plating, I like to scoop out generous portions from the lasagna so the beautiful layers of vibrant green spinach and peas peek through the creamy sauces. A garnish of fresh basil leaves or a sprinkle of extra nutritional yeast on top adds an elegant touch and enhances the flavors. This dish shines best served warm, right out of the oven, but it’s still delicious at room temperature if you’re setting it out for a casual gathering.

For drinks, I recommend pairing this lasagna with a chilled glass of crisp white wine like Sauvignon Blanc or a light, herbaceous gin cocktail. If you prefer non-alcoholic options, a sparkling water with fresh lemon or cucumber slices complements the dish perfectly. This recipe is fantastic for family dinners, holiday meals, or potlucks, and it’s always a crowd-pleaser that leaves everyone asking for seconds.

Variations

One of my favorite things about this recipe is how versatile it is. If you want to keep it gluten-free, simply swap out the no-boil lasagna noodles for gluten-free lasagna sheets—you may need to adjust the layering or hydration time slightly but it will still come together beautifully. For a lower-fat version, you can reduce the olive oil or substitute some cashews in the ricotta with silken tofu to lighten the texture.

If you want to switch up the veggies, I’ve found that sautéed mushrooms, artichoke hearts, or zucchini ribbons are fantastic additions or swaps for the peas and spinach. Sometimes I add roasted butternut squash for a touch of sweetness and color. Flavor-wise, experimenting with fresh herbs like thyme or oregano in the ricotta or sauce can bring a new dimension to the dish that feels pleasantly surprising.

I’ve also tried baking this lasagna in smaller, individual ramekins for a fun, personalized presentation—perfect for dinner parties. Alternatively, making it ahead and refrigerating overnight before baking actually enhances the layering flavors. Just be sure to let it come to room temperature before popping it in the oven for even baking.

Storage and Reheating

Storing Leftovers

If you have leftovers (which is a happy problem!), store them chilled in an airtight container. I usually use glass containers with tight-fitting lids because they keep the lasagna fresh and prevent it from absorbing other fridge odors. Stored properly, this vegan white lasagna will keep well for about 3 to 4 days, making it perfect for easy lunches or dinners during the week.

Freezing

This lasagna freezes wonderfully, which is great if you want to prepare it in advance or save portions for later. To freeze, let the lasagna cool completely, then wrap the baking dish tightly with plastic wrap followed by a layer of foil, or transfer portions into freezer-safe containers. It will keep in the freezer for up to 3 months. When you’re ready to enjoy, thaw it overnight in the fridge for best results.

Reheating

For reheating, I find the oven method works best to preserve the creamy texture and crispy top. Preheat your oven to 350 degrees Fahrenheit, cover the lasagna with foil to avoid drying out, and heat for about 20 to 30 minutes until warmed through. Avoid microwaving if possible, as it can sometimes make the layers soggy or unevenly heated. If you do use a microwave, heat on medium power in intervals and let it rest a minute between rounds to help even out the temperature.

FAQs

Can I use regular lasagna noodles instead of no-boil?

Absolutely! If you only have regular lasagna noodles, just cook them according to the package directions until al dente before layering. Be sure to drain and pat them dry to avoid excess water, then follow the rest of the recipe as usual.

Is the cashew ricotta very difficult to make?

Not at all! It’s simply a matter of blending all the ingredients until smooth. Having a good food processor helps, but even a strong blender can work. The cashews soften with soaking or blending, and the tofu adds creaminess and protein—anyone can master this with a few minutes of blending.

Can I prepare this vegan white lasagna ahead of time?

Yes! I often assemble it a day ahead, cover it tightly, and keep it in the refrigerator until baking time. This actually improves the flavors and helps the noodles soak up the sauce perfectly.

What if I don’t have nutritional yeast?

Nutritional yeast adds a lovely cheesy flavor and helps the top brown nicely, but if you don’t have it, you can simply omit it or sprinkle some finely chopped fresh herbs or a dash of smoked paprika for a different flavor boost.

Is this recipe suitable for gluten-free diets?

It can be easily modified! Just swap the no-boil lasagna noodles with gluten-free ones. Make sure they’re also no-boil or pre-cook them ahead. Everything else in the recipe is naturally gluten-free, so it’s a simple switch to make it suitable.
