This recipe for Grilled Zucchini Lasagna is for vegetable gardeners who might be wondering how to use those huge zucchinis that suddenly seem to appear overnight when the garden is winding down. For years I’ve been making “lasagna” using zucchini in place of the lasagna noodles, and this is one of my favorite uses for those monster zucchinis so I’m reminding you about it for Friday Favorites this week to entice you to try it!
Grilling the zucchini removes some of the liquid that might otherwise make the lasagna too watery, and if you don’t have an outdoor grill you could certainly do this step on a stove-top grill pan (affiliate link). Of course, using zucchini instead of pasta makes a delicious version of lasagna that’s low in carbs, gluten-free, and South Beach Diet friendly, and it can also be vegetarian if you don’t add sausage to the sauce!
How to Make Grilled Zucchini Lasagna:
(Scroll down for complete printable recipe plus nutritional information.)
- I use lengthwise slices of zucchini about 5/8 inch thick.
- Brush the zucchini slices on both sides with olive oil, adding a sprinkle of Italian Herb Blend if you’d like.
- Grill on the first side until you have nice grill marks, about 3-4 minutes. Then turn and cook a few minutes on the second side, until the zucchini is partially cooked but not completely soft.
- I used to make this with my Sausage and Basil Marinara Sauce, but now I’d use Rao’s Pasta Sauce (affiliate link) which has only 20 carbs in the whole jar. Use a sauce with meat or a meatless sauce, whichever you prefer. Simmer the sauce a few minutes to evaporate some of the water so you have a thick sauce.)
- Spread the cooked zucchini out on a large cutting board and use a paper towel to press down and remove as much liquid as you can.
- Beat the eggs and then mix in the cottage cheese. (Don’t skip the eggs; they help hold this together.)
- Spray the baking dish with olive oil or non-stick spray and then make a layer of the grilled zucchini.
- Cover that with half the sauce, about 1 cups of the thick sauce, or a little more if you didn’t simmer it.
- Then make a layer with half the cottage cheese mixture, followed by a layer with half the cheese.
- Repeat to make another layer each of grilled zucchini, sauce, cottage cheese-egg mixture, and cheese.
- Bake at 400F/200C for 30-40 minutes, or until the lasagna is bubbling and the top is starting to brown. I baked mine uncovered so water would evaporate, but you can cover with foil towards the end of the cooking time if it starts to look too brown.
- This will be juicier than regular lasagna, so let it sit at least 10-15 minutes before cutting.

Thick slices of barely-grilled zucchini replace the noodles in this Grilled Zucchini Low-Carb Lasagna. I've used my Sausage and Basil Marinara Sauce many times to make the sauce for this lasagna but now I'd probably use Rao's Pasta Sauce (affiliate link) for even less carbs. You can add cooked Italian Sausage and chopped fresh basil to the sauce when you simmer it if you prefer. (Nutritional information does not include optional sausage and is calculated using the low-carb sauce I recommend.) You need enough zucchini slices to make two layers, be careful not to cut the zucchini too thin. It’s important to use a dish that’s fairly deep for this recipe. I used my new lasagna pan that was 12.5″ x 10″ and 3″ deep, which worked perfectly. This recipe created by Kalyn. Nutrition information is automatically calculated by the Recipe Plug-In I am using.

Low-Carb Diet / Low-Glycemic Diet / South Beach Diet Suggestions:
Grilled Zucchini Lasagna will be much lower in carbs than traditional lasagna when it’s made with low-sugar pasta sauce like Rao’s Pasta Sauce (affiliate link). However even low-sugar sauce has some carbs and there are carbs in the cottage cheese, so this recipe is probably not Keto. For anyone who’s following the original South Beach Diet, this should be made with reduced fat dairy products for South Beach. This does have a fairly generous amount of cheese, so even though this would be okay for any phase of South Beach, it’s probably a personal choice treat for Phase One.

I would like to know if I can use ricotta cheese instead of cottage. It is less soupy. Do you think it would work out?
Yes, I think ricotta cheese will be great in this.
I have made this twice now using Ricotta and all I did was reduce the eggs by 1. It is a delicious recipe, thank you Kalyn.
Ed, so glad to hear you are enjoying it!
We made this last night and it was absolutely delicious! Pretty much followed your recipe exactly – no Rao’s (my favorite marinara), unfortunately, but the bought sauce we used was still delicious – except we lost electricity about half way through (our neighbor managed to mow down the electric lines. How? That’s anyone’s guess.). When the electricity came back on, we forgot that the oven heats up with both the bottom and top heat sources. We ended up with a very brown cheesy crust on top. And it was a happy mistake because it was absolutely delicious! This will be a regular, especially in summer when the garden bounty of zucchini is almost overwhelming. Thank you!
That sounds like quite an adventure! So glad it still worked out and that you enjoyed it!
I make this several times each summer. It’s a family favorite. ‘This year there were reasons I did not want to grill. I just seared the slices on my stove top flat grill. No grill marks, just browned, but who cares? No one sees the grill marks anyway. Definitely better 2nd day.
And I used chicken Italian sausage too. 1/2 hot and 1/2 mild.
So glad you’re enjoying the recipe! Thanks for sharing your tips!
Made this last night and it was SO delicious. My teenager daughter and husband loved it too. I made it with Italian chicken sausage and minced chicken (1/2 and 1/2). Will definitely be making this again, thanks!
So happy to hear you enjoyed it!
