Step‑by‑Step Instructions for Pesto Zucchini Lasagna
Step 1: Prep Zucchini
Begin by slicing the zucchini into 1/4” rounds. Sprinkle the slices with salt and let them sit for about 20 minutes. This process draws out excess moisture, ensuring each layer remains flavorful and doesn’t release water while baking. Once time’s up, rinse the zucchini slices under cool water and pat them dry with paper towels to absorb any excess salt.
Step 2: Blanch Greens
Next, fill a pot with water and bring it to a rolling boil. Meanwhile, prepare an ice bath in a large bowl with cold water. Add the kale and basil to the boiling water and blanch for 60 seconds. Quickly transfer the greens to the ice bath to stop the cooking process and retain their vibrant color. Once cooled, remove them and squeeze out any excess water thoroughly.
Step 3: Make Pesto
In a blender or food processor, combine the blanched greens, toasted pumpkin seeds, garlic, olive oil, lemon juice, a pinch of salt, and a bit of water. Blend until you achieve a mostly smooth consistency, adjusting the water gradually to reach your desired thickness. This nutty, vibrant pesto will be used to bring your Pesto Zucchini Lasagna to life.
Step 4: Assemble Lasagna
Preheat your oven to 375°F (190°C). In a bowl, mix one-third of the prepared pesto with the ricotta cheese. Spoon one-third of the remaining pesto into the base of a baking dish, then layer one whole wheat lasagna noodle on top. Add a layer of the ricotta mixture, followed by zucchini slices and sliced scallions. Repeat the layering process until all ingredients are used, finishing with a final noodle.
Step 5: Top Lasagna
Spread the last portion of pesto over the top noodle layer, ensuring even coverage. Generously sprinkle mozzarella cheese on top, creating a deliciously melty topping for your Pesto Zucchini Lasagna. This rich layer will add a perfect finishing touch to your dish, readying it for the oven.
Step 6: Bake
Carefully place the assembled lasagna in the preheated oven and bake for approximately 30 minutes. Keep an eye on it; you’ll know it’s ready when the cheese is bubbling and has turned golden brown. This provides a beautiful texture and flavor balance to your lasagna.
Step 7: Rest & Serve
Once baking is complete, remove your Pesto Zucchini Lasagna from the oven and allow it to rest for about 5 minutes. This resting period helps the layers set, making it easier to slice. After resting, cut into squares and serve warm, relishing the comforting blend of flavors from this delightful dish.

Expert Tips for Pesto Zucchini Lasagna
-
Squeeze Greens Thoroughly: After blanching the kale and basil, be sure to squeeze out excess water. This prevents a watery pesto, ensuring rich flavor in your Pesto Zucchini Lasagna.
-
Uniform Zucchini Slices: Slice zucchinis evenly to ensure they cook at the same rate. This guarantees a uniformly tender texture throughout your lasagna.
-
Mind the Pesto Texture: Blend your pesto just until mostly smooth to keep a rustic consistency. Overblending can turn it too creamy, losing that delightful texture.
-
Rest Before Slicing: Let your lasagna cool for about 5 minutes after baking. This resting period helps the layers set, allowing for clean, beautiful slices.
-
Experiment with Ingredients: Don’t hesitate to swap out ingredients based on your preferences! Alternatives like roasted eggplant or different nuts for the pesto can give exciting new flavors.
