Why You’ll Love this Eggplant Zucchini Lasagna:
If you’re like me and trying to figure out how to use an abundance of summer squash, this recipe is for you. This zucchini lasagna recipe features layers of creamy pesto ricotta, fresh mozzarella, and sweet cherry tomatoes. It’s really one of the most delicious uses of ALL peak-summer produce: zucchini, tomatoes, and basil.
And even though it’s vegetarian, it’s plenty hearty and satisfying. You can serve it as the main entree, or a side dish to complement just about any protein. For example, baked fish, meatballs, or balsamic tofu.
Both kids and adults will love this fresh summertime lasagna. Plus, it makes for some amazing leftovers, so you can enjoy it on repeat!
- Zucchini: You need two large (or 3 medium) zucchinis for this recipe. You want to slice the zucchini crosswise into 1/2-inch think slices.
- Eggplant: You need one large (or 2 small) globe eggplants for this recipe. Globe eggplants are larger, oblong shaped eggplants with the dark purple shiny skin.
- Tomatoes: One full pint of cherry tomatoes goes into this lasagna, which add a sweet burst of umami. Feel free to use red, golden, or multi-colored tomatoes–whatever looks best!
- Cheese: Whole-milk ricotta and mozzarella cheese make up the cheesy dynamic duo in this recipe. If you prefer, you can use part-skim ricotta, however the whole-milk variety is so much richer and creamier. Alternatively, you can use Kite Hill’s brand of ricotta cheese, which is dairy free.
- Pesto: You can either use homemade or jarred pesto for this recipe. If using jarred, I highly recommend DeLallo’s brand of pesto, which has the freshest flavor of any I’ve tried.
- Panko: This zucchini lasagna gets topped with a golden, garlicky panko topper, which adds lots of texture. While the panko topping is optional (especially if you’re gluten free), it does really round out the dish.
Step 1: Slice Eggplant and Zucchini
Start by trimming off and discarding the ends of the eggplant and zucchinis. Next, slice each vegetable crosswise into 1/2-inch thick slices.
Step 2: Bake Eggplant, Zucchini, and Tomatoes
Grease two baking sheets with about 1 Tbsp. olive oil. Arrange eggplant slices in a single layer on one of the baking sheets, then fit as many pieces of zucchini as possible on same baking sheet. Lightly spray eggplant and zucchini with cooking spray, and sprinkle lightly with salt.
On the other baking sheet, arrange remaining zucchini slices on one half, and the tomatoes on the other half. Lightly spray with cooking spray and sprinkle with salt.
Place sheet with eggplant on lower rack and sheet with tomatoes on upper rack and roast until eggplant is browned and tomatoes are blistered, about 25 to 30 minutes.
Step 3: Prepare Pesto Ricotta Mixture
In a medium bowl, combine ricotta cheese, pesto, and 1/2 tsp. red pepper flakes. Stir to combine, and set aside.
Step 4: Assemble Eggplant Zucchini Lasagna
Drizzle some olive oil into a shallow 2-qt. baking dish. Arrange one half of zucchini and eggplant slices in a single layer (it’s OK if there is some overlap), and scatter one half of blistered tomatoes overtop. Next, dollop half of ricotta mixture over tomatoes.
Repeat layering process one more time, using up remaining vegetables and ricotta mixture. Scatter mozzarella cheese overtop.
Lastly, in a small bowl, combine panko, garlic powder, and 1 Tbsp. olive oil; mix with your fingers to combine. Scatter panko mixture over the lasagna.
Step 5: Bake Zucchini Lasagana
Transfer the baking dish to the oven, and bake for about 20 to 22 minutes, until bubbly and golden. Remove from the oven, and let rest for 5 minutes before scattering fresh basil overtop and serving.
FAQs and Expert Tips
Should You Salt Zucchini Before Cooking?
Both the zucchini and eggplant are lightly salted before roasting, which helps draw out some of their moisture. However, you do NOT need to let the zucchini and eggplant rest after salting. Just pop them right in the hot oven, which will naturally evaporate some of their water content.
Is this Zucchini Lasagna Low Carb?
Since no noodles are used in this lasagna, it is naturally low in carbs and rich in fiber. The panko topping does add additional carbohydrates (and gluten), however you can leave it off if you’re limiting carbs.
How Long Does Eggplant Zucchini Lasagna Last?
Since this lasagna is meatless, it will last up to 4 days refrigerated. To reheat, either nook individual portions in the microwave, or transfer the whole pan back to the oven. If doing the latter, I suggest heating at 300ºF until warmed through.
