Zucchini Lasagna Recipe (2024)

You won’t miss the pasta with this comforting, satisfying Zucchini Lasagna Recipe! It includes layers of tender zucchini, Italian sausage marinara and plenty of cheese. It’s a low carb, gluten-free dinner that can be prepped in advance!

I’m craving all the comfort foods lately, and lasagna has been high on my list. While my skillet lasagna recipe is one of my favorite things to prepare, I try not to eat a lot of pasta in order to minimize my gluten intake.

This Zucchini Lasagna recipe is what I turn to when I crave lasagna but I don’t want the pasta. It’s a comforting, satisfying alternative that my entire family is on board with, even my college aged boys.

It’s packed with flavorful Italian sausage, my homemade marinara sauce and a layer of creamy ricotta cheese that takes it over the top.

I’ve always been a fan of zucchini noodles smothered in pasta sauce, but they are very costly and they cook up to almost nothing.

Purchasing whole zucchini and slicing it is so much more cost effective, and it really doesn’t take that much effort to prep.

This recipe will truly surprise you and I promise you won’t miss the pasta. 🙂

Recipe ingredients

There are just a few ingredients included in this keto lasagna recipe, but it can be customized a number of different ways based on your favorite protein source or sauce.

Ingredient notes

• Zucchini. You’ll need roughly 2 lbs. of zucchini, or about 3-4 depending on size. I like to use larger sized zucchini that will fit all the way across the baking dish, and I always make one extra to ensure that I have plenty….I typically don’t use the ends in the lasagna. If you have leftover grilled zucchini, it’s great in my grilled vegetable salad, orzo pasta salad or as a simple side dish!
• Italian sausage. The Italian sausage is the secret weapon in this zucchini lasagna recipe. It packs plenty of flavor and eliminates the need for additional onion and garlic (it’s already in the marinara sauce).
• Marinara sauce. I love having a batch of my homemade marinara sauce in the freezer for meals just like this. You will need 28 ounces, or about 2 1/2 cups. Feel free to substitute it with your favorite store bought sauce. This can be substituted with my homemade meat sauce if you prefer ground beef.
• Ricotta cheese. The ricotta cheese adds a creamy layer that sets this lasagna apart. You can add greens to it the way I did in my spinach and ricotta stuffed shells to add even more nutrition. The ricotta may also be substituted with cottage cheese if you prefer.
• Egg. The egg is used as a binder for the ricotta filling.
• Mozzarella cheese. For best results, do not use pre-grated mozzarella cheese as it includes preservatives to keep the cheese from clumping and sticking together. I grated a 12 ounce ball of fresh mozzarella, which took just a few minutes, and it can be done a few days in advance.
• Parmesan cheese. The parmesan adds plenty of umami flavor to the ricotta filling.
• Basil. Fresh basil is added to the ricotta filling for added flavor, and I love topping the lasagna with additional basil when serving it.

How to make keto zucchini lasagna

This keto zucchini lasagna recipe is extremely easy to prepare, and the zucchini and sauce may be prepared in advance to make it go even more quickly on busy nights.

Pro tip: Cut the zucchini in 1/4″ thick slices or even thinner using a mandoline if desired. While you don’t have to cook the zucchini before assembling the lasagna, I highly recommend doing so as it reduces the amount of water in the zucchini.

See the recipe card below for full instructions.

Cook the zucchini (optional but recommended)

Zucchini is about 94% water, so it’s important to cook it prior to assembling the lasagna. This won’t eliminate all of the water, but it significantly reduces it!

Prepping the zucchini for this zucchini lasagna recipe can be done up to a few days in advance to save time on busy weeknights.

I don’t own a mandoline, so I just do my best to cut the zucchini as thinly and evenly as possible. Using a mandoline will definitely allow you to slice it even thinner and will be much more consistent in thickeness.

1. Cut the zucchini into 1/4″ thick slices as evenly as possible.
2. Toss the zucchini in olive oil and salt and pepper to taste.
3. Grill over medium high heat for 2-3 minutes per side or until tender (not mushy). You can also bake the zucchini at 450 degrees for 2-3. minutes per side if you prefer, but grilling it is more effective in reducing water.
4. Blot the cooked zucchini dry to remove any excess water.
