These ingredients might sound simple, but each one is essential to build the perfect harmony of flavors and textures in this Springtime White Lasagna Recipe. From creamy cashews to fresh vegetables and fragrant herbs, every component plays a role in crafting this memorable dish.
- 1 whole head of garlic (reserve 2-3 cloves): Roasted for a mellow, sweet depth and reserved cloves provide a fresh garlic kick.
- 1 cup raw unsalted cashews (soaked for 2-3 hours): Creates a smooth, velvety sauce base with creamy texture.
- 2 cups vegetable or chicken broth (low-sodium): Adds savory flavor without overpowering the delicate veggies.
- 2 cups unsweetened almond milk: Lightens the sauce, making it silky and dairy-free.
- 3 tablespoons arrowroot starch: Thickens the sauce gently for a luscious consistency.
- 3 tablespoons nutritional yeast (optional): Brings a subtle cheesy flavor without dairy.
- 1 teaspoon kosher salt (more to taste): Balances and enhances all the flavors.
- Black peppercorn (to taste): Adds a mild, warming spice.
- 4 sprigs of fresh thyme: Infuses the sauce with an aromatic herbal note.
- 2-3 cloves garlic (from the reserved garlic): Provides fresh garlic aroma in the vegetable mixture.
- 2-3 leeks (adjust based on leek size): Adds a subtle oniony sweetness and soft texture.
- 2 bunches (~600g) asparagus: The star spring vegetable, crisp and tender.
- 1 box (283g) baby spinach: Adds mild earthy flavor and vibrant color.
- 1 box (~280g) no-boil lasagna sheets (gluten-free or regular): Makes layering effortless and soaks up the flavors beautifully.
- Avocado oil (or other high-heat oil for sautéing): Used for gentle cooking of veggies without burning.
- Kosher salt (to taste): Seasoning for sautéed vegetables and finishing.
How to Make Springtime White Lasagna Recipe
Step 1: Soak the Cashews
Start by soaking the cashews in water for 2-3 hours or overnight to soften them. This step is crucial to achieve that ultra-creamy texture in the sauce later. Once soaked, drain and set these aside — they’re going to transform into a luxurious garlic cream that holds this dish together.
Step 2: Roast the Garlic
Preheat your oven to 450°F (232°C). Take the whole head of garlic, slice off the tip to expose the cloves, sprinkle with a little salt, then wrap it tightly in foil. Roast for 45 minutes until the cloves are soft, fragrant, and golden. This roasted garlic will give the sauce its mellow, sweet richness that is simply irresistible.
Step 3: Prepare the Vegetables
While the garlic cools, prepare your veggies. Mince the 2-3 reserved garlic cloves. Trim the dark green tops off the leeks, keeping the tender white and pale green parts, then rinse to remove any grit; slice into half-inch rounds. Snap off woody ends of asparagus and chop the stalks into one to one-and-a-half-inch pieces — save a few whole stalks for garnish if you like. Wilted baby spinach is ready to join the party too, making this dish both nutritious and colorful.
Step 4: Make the Roasted Garlic Sauce
Squeeze the cooled roasted garlic cloves out of their skins and add them to a blender with the soaked cashews, vegetable broth, almond milk, arrowroot starch, optional nutritional yeast, kosher salt, black pepper, and fresh thyme sprigs. Blend these together until you get a silky, smooth sauce. Pour the sauce into a pot and gently simmer it over low heat for 5 minutes, stirring often until it thickens slightly and all the flavors meld wonderfully.
Step 5: Sauté the Vegetables
Heat avocado oil in a skillet on medium. Add the sliced leeks with a pinch of salt and sauté for 8-10 minutes until softened and fragrant. Toss the minced garlic in for another 2 minutes so it can bloom and add flavor. In a separate pan, wilt the spinach in batches, then squeeze out any excess moisture, ensuring your lasagna won’t turn watery. These tender veggies are ready to create layers that will shine through every forkful.
Step 6: Assemble the Lasagna
Turn your oven down to 375°F (190°C). Spread half a cup of the roasted garlic sauce on the bottom of your baking pan, then layer with no-boil noodles. Alternate the layers with more garlic sauce, sautéed leeks, wilted spinach, chopped asparagus, and noodles until you run out. Save any whole asparagus stalks to place on top as a pretty garnish. Finish by spreading the remaining sauce over the top and, if you like, sprinkle with a bit of nutritional yeast or dairy-free cheese for a subtle crust.
Step 7: Bake the Lasagna
Cover the lasagna with foil sprayed with cooking spray so it doesn’t stick to the foil during baking. Bake for 30-35 minutes, then remove the foil and bake uncovered for another 8-10 minutes until the top looks golden and starts bubbling. Let the lasagna rest for 10 minutes before digging in — this resting time lets the layers set so every slice holds perfectly together.
How to Serve Springtime White Lasagna Recipe
Garnishes
For a fresh and elegant touch, place whole roasted asparagus stalks on top of your lasagna before serving. A sprinkle of fresh thyme leaves or an extra dusting of nutritional yeast adds a lovely finish that elevates the dish’s springtime vibes.
Side Dishes
This white lasagna pairs beautifully with light spring salads such as a lemony arugula salad or a crisp cucumber and radish slaw. For something heartier, garlic roasted baby potatoes or crusty artisan bread make wonderful companions without overpowering the delicate flavors.
Creative Ways to Present
You can transform this recipe into individual servings using small ramekins or mini baking dishes — perfect for entertaining or meal prep. Alternatively, serve it family-style right from the baking dish, allowing the gorgeous layers and steaming sauce to impress your guests and spark conversation at the table.
Make Ahead and Storage
Storing Leftovers
Once completely cooled, store any leftover lasagna in an airtight container in the refrigerator. It will keep beautifully fresh for 3-4 days, maintaining its creamy texture and vibrant vegetable flavors.
Freezing
This Springtime White Lasagna Recipe also freezes well. Cover the cooled lasagna tightly with plastic wrap and foil, or use a freezer-safe container, and freeze for up to 2 months. When ready to enjoy, thaw overnight in the fridge for best results.
Reheating
Reheat individual portions gently in the microwave or reheat the entire dish covered with foil in a 350°F (175°C) oven until warmed through, about 20-30 minutes, to preserve the sauce’s creaminess and avoid drying out the vegetables.
FAQs
Can I use regular milk instead of almond milk?
Absolutely! Regular milk can be used in place of almond milk if you’re not avoiding dairy. It will still give you that creamy texture, just slightly richer. For a dairy-free version, almond milk is perfect.
Do I have to soak the cashews overnight?
Not necessarily. Soaking cashews for 2-3 hours softens them enough for blending, but soaking overnight is fine if you want to prep ahead or save time when you cook.
Can I substitute the asparagus for other vegetables?
Definitely! Spring vegetables like zucchini, peas, or green beans would work nicely and offer a new twist on this lasagna, but asparagus lends a classic fresh bite that pairs beautifully with the creamy sauce.
Is the nutritional yeast necessary?
It’s optional but highly recommended for a subtle cheesy flavor, especially if you’re aiming for a dairy-free, vegan-friendly lasagna. You can omit it if you want, and the sauce will still be delicious.
Can I prepare this lasagna ahead of time for a party?
Yes, you can assemble the lasagna up to a day in advance, cover it tightly, and refrigerate. Bake it fresh right before serving for the best bubbly, golden finish and fresh textures.

Ingredients
Roasted Garlic Sauce
- 1 whole head of garlic (reserve 2–3 cloves)
- 1 cup raw unsalted cashews (soaked for 2–3 hours)
- 2 cups vegetable or chicken broth (low-sodium)
- 2 cups unsweetened almond milk
- 3 tablespoons arrowroot starch
- 3 tablespoons nutritional yeast (optional)
- 1 teaspoon kosher salt (more to taste)
- Black peppercorn (to taste)
- 4 sprigs of fresh thyme
- 2–3 cloves garlic (from the reserved garlic)
Vegetables and Lasagna
- 2–3 leeks (adjust based on leek size)
- 2 bunches (~600g) asparagus
- 1 box (283g) baby spinach
- 1 box (~280g) no-boil lasagna sheets (gluten-free or regular)
- Avocado oil (or other high-heat oil for sautéing)
- Kosher salt (to taste)
Instructions
- Soak the Cashews: Begin by soaking the raw unsalted cashews in 2 cups of water for 2-3 hours, or overnight if you prefer. This softens them for blending into the creamy sauce. After soaking, drain and set them aside.
- Roast the Garlic: Preheat your oven to 450°F (232°C). Slice off the tip of the whole garlic head to expose the cloves, then sprinkle with a pinch of salt. Wrap the garlic head tightly in foil and roast in the oven for 45 minutes until the cloves are soft and fragrant. Remove and let cool.
- Prepare the Vegetables: Mince the reserved 2-3 garlic cloves. Trim the leeks by removing the dark green parts and keeping the white and pale green sections. Cut them in half lengthwise, rinse thoroughly, and slice crosswise into half-inch pieces. Snap the woody ends off the asparagus and chop the stalks into 1 to 1.5-inch pieces, setting aside 3 whole stalks for garnish if desired. For thicker stalks, cut them lengthwise in half.
- Make the Roasted Garlic Sauce: Once the roasted garlic has cooled, squeeze the softened cloves out of their skins into a blender. Add the soaked cashews, vegetable broth, almond milk, arrowroot starch, nutritional yeast (if using), kosher salt, black pepper, and thyme sprigs. Blend until completely smooth. Transfer the sauce to a medium pot and gently simmer over low heat for 5 minutes, stirring occasionally. Taste and adjust seasoning with additional salt or pepper as needed. Set aside.
- Sauté the Vegetables: Heat avocado oil in a skillet over medium heat. Add the sliced leeks and a pinch of kosher salt; sauté for 8-10 minutes until softened. Stir in the minced garlic and cook for another 2 minutes. In a separate pan, sauté baby spinach in batches until just wilted. Drain and squeeze out any excess moisture from the spinach. Keep set aside.
- Assemble the Lasagna: Preheat the oven to 375°F (190°C). In a lasagna pan, spread ½ cup of the roasted garlic sauce on the bottom. Lay down a layer of no-boil lasagna noodles, then add layers alternating between sauce, sautéed leeks, wilted spinach, raw chopped asparagus, and noodles. Repeat layering until ingredients are used up. Garnish with the reserved whole asparagus stalks on top, then cover with the remaining sauce. Optionally, sprinkle a little nutritional yeast or dairy-free cheese on top.
- Bake the Lasagna: Cover the assembled lasagna with aluminum foil sprayed with cooking spray to prevent sticking. Bake for 30-35 minutes covered. Remove the foil and bake uncovered for an additional 8-10 minutes until the top is golden and bubbly. Allow the lasagna to rest for 10 minutes before slicing and serving.
Notes
- Soaking cashews overnight softens them better for a creamier sauce but 2-3 hours is sufficient.
- Use no-boil lasagna noodles to save time and simplify assembly.
- If preferred, substitute almond milk with another unsweetened plant-based milk.
- Arrowroot starch helps thicken the sauce but cornstarch can be a substitute.
- Adjust seasoning to taste after simmering the sauce as flavors intensify with cooking.
- For a gluten-free option, ensure noodles and broth are gluten-free certified.
- Leftover lasagna can be refrigerated and reheated for up to 3 days.
