Zucchini Lasagna

Filled with layers of sliced summer squash, this zucchini lasagna is a great option for using summer produce. Zucchini slices replace the pasta in this simple vegetarian dish.

Zucchini is one of my favorite vegetables, and every summer I love coming up with different ways to use it.

Sure, there’s classic zucchini bread, but the mild flavor of zucchini works well with so many other things, especially in savory dishes.

This zucchini lasagna is a dish I love to make when I feel like I haven’t been eating enough vegetables.

It skips the layers of pasta noodles in favor of slices of tender zucchini, making this a lighter dish that’s ideal for summertime.

If you’ve got too much zucchini in your garden, give this recipe a try!

Ingredients for zucchini lasagna

You’ll need:

Zucchini – Look for zucchini that fits your baking pan well, but is not too large.

The zucchini should be firm with no soft spots. Scarring is OK!

Try different varieties of zucchini or use a mix of zucchini and yellow crookneck squash.

Ricotta cheese – I prefer to use regular-fat ricotta or make ricotta from scratch.

You can use lowfat ricotta if you prefer, or swap in cottage cheese for some or all of the ricotta.

Egg – Add 1 egg to the cheese mixture for the filling.

Parmesan cheese – I like to add parmesan to the ricotta filling for additional flavor. Buy a chunk and grate it at home — you’ll save money in the long run and your cheese will taste fresher!

Mozzarella cheese – More cheese! Add melty mozzarella in the layers and on top.

Herbs and spices – This recipe calls for salt, pepper, dried basil, dried oregano, and crushed red pepper flakes.

Pasta sauce – Use your favorite marinara sauce or flavored pasta sauce.

Tomato – This is optional, but I like to add a sliced tomato to the top of the lasagna for extra flavor and a nice presentation.

How to make this recipe

Preheat the oven to 350°F.

Trim off the ends of the zucchini, then slice thinly lengthwise. Salt the zucchini on both sides and place in a colander set in the sink.

Let rest for 10-15 minutes while you prepare the rest of the ingredients. You should start to see water droplets on the surface of the squash after a few minutes.

In a medium bowl, mix together the ricotta, parmesan, egg, basil, oregano, ½ teaspoon salt, black pepper, and red pepper flakes until evenly mixed.

Spread ½ cup of the pasta sauce on the bottom of an 11×7.5-inch casserole dish.

Rinse the drained squash and pat dry. Arrange in an even layer on top of the sauce, cutting slices as needed to fill any gaps. If you like, do a double layer of squash, alternating placement.

Spread on half of the ricotta mixture, then sprinkle on ¾ cup of the mozzarella. Top with ¾ cup pasta sauce.

Repeat layers with the squash, remaining cheese, mozzarella, and pasta sauce. You might not use all of the squash slices.

Top with sliced tomato and remaining mozzarella.

Bake for 45 minutes, until cheese is browned and sauce is bubbly.

Let cool for at least 10 minutes before serving.

Tips and tricks

To ensure the lasagna is not overly watery, make sure to salt the zucchini slices and let rest for at least 10 minutes. The salt will draw out excess moisture as it soaks into the zucchini.

Another way to reduce the liquid is to cook the zucchini ahead of assembling the lasagna. Grill, roast, or sear the zucchini until soft but not falling apart.

If you find the lasagna is too watery after baking, try this hack: Use a turkey baster in the corners of the pan to remove excess liquid.

Make this dish meaty by adding cooked Italian sausage to the pasta sauce.

  1. Brilliant! I love the flavor combinations of squash, tomatoes, and fresh herbs. I did try this with zucchini once, but used the huge as an arm zucchini I’d let get away from me in the garden and the results were less than stellar. (hard seeds! woody flesh! what was i thinking!?!) You’ve inspired me to give at another (better) go.

    1. @Cindy I didn’t have any issue with the moisture levels once I thawed it. It was a little crumbly at first but after letting it warm up and giving it a good stir it was back to its original texture.

  2. Ooh! Love new uses like this for using up a large-ish amount summer squash… and gf lasagna noodles are such a pain. Win win! Thanks for this.

  3. right, i totally think of lasagna as a winter dish. i basically only make it during the holiday season, so this is a cool idea, plus with it being gluten-free and all.

  4. Hi, Megan! I was led to your blog while looking for fellow foodies in Austin. Your blog is lovely, and I love your style of writing! So easy and entertaining to read. I’ve also been trying to teach my husband to just put together something on his own, but I end up taking over. His creations…well, they need help! I love this recipe! Perfect for our brutal summer months. Thank you!
