Zucchini lasagna gives you 30g protein per serving with just 15g carbs. Pretty solid nutrition. Naturally gluten-free too.
Here’s the thing – most zucchini lasagna turns out watery. You slice your zucchini, layer it up, and end up with soup. I’ve been there.
Zucchini releases tons of moisture when cooked. That’s just what it does.
Good news – you can fix this. Salt your zucchini first. Grill it or roast it. Simple steps that work.
The key is removing water before you build your lasagna. Do this right and you get firm layers that hold their shape.
I’ll show you exactly how to prep your zucchini, make the fillings, and put it all together. No more soggy mess.
Prep Your Zucchini Right

Zucchini is 94% water. That’s your enemy right there.
Pick the right zucchini
Look for dark green, firm zucchini with smooth skin. No soft spots or blemishes. Straight and long makes layering easier.
I use medium-sized ones – you’ll need about 4-5 medium or 2-3 large. Should feel heavy for the size. That means fresh.
Slice them thin and even
Get a mandolin if you don’t have one. Makes this so much easier. Slice lengthwise, about 1/8-inch thick, not 1/4-inch. Thinner slices release less water.
Sharp knife works too if that’s what you’ve got. Just harder to get them even. Don’t use a vegetable peeler – slices won’t hold up.
Salt and wait
Lay your slices on paper towels in a single layer. Sprinkle with kosher salt and let them sit 15-30 minutes. Salt pulls out the moisture.
Blot them every 5-10 minutes with fresh paper towels. Pat dry one more time before using.
Grill or roast for extra drying
Want really firm layers? Grill the salted slices on medium heat, 1-2 minutes per side. No oil needed.
Or roast at 400°F for 15-20 minutes until mostly dry. For broiling, put them on racks, light spray of oil, broil 5 inches from heat for 4-6 minutes.
This extra step makes all the difference.
Make the Meat Sauce and Cheese Filling
Good fillings make the difference. You want flavor without adding more water to your lasagna.
Cook ground beef or turkey with herbs and sauce
Heat a large skillet over medium-high heat. Add your ground beef or turkey. I use ground chuck – the fat keeps things from drying out.
Brown the meat completely. Break it up with a spatula until no pink shows. Takes about 10 minutes.
Drain the fat, then add minced garlic and onion if you want. I always do. Sauté for 3-5 minutes until soft.
Stir in 1½ cups marinara sauce. Pick a no-sugar-added brand for keto. Season with oregano, basil, and Italian seasoning – ½ teaspoon each. Let it simmer 5-10 minutes.
Mix ricotta, egg, and optional spinach
Mix ricotta cheese with one egg in a bowl. The egg helps everything hold together. Add ½ cup shredded mozzarella and ⅓ cup Parmesan. Season with salt, pepper, and more Italian herbs.
Some people use cottage cheese instead of ricotta. If you do, drain it first.
Want to add spinach? Thaw frozen spinach and squeeze out every drop of water. Seriously – squeeze it hard. Extra water ruins everything.
Skip low-fat cheese
Full-fat dairy only. Low-fat cheese has more water added to make up for missing fat. That water goes straight into your lasagna.
Fresh mozzarella tastes great but releases too much liquid. Stick with block or pre-shredded mozzarella instead.
Real Parmesan adds flavor without extra moisture. The shelf-stable stuff works fine too.
Putting It All Together

Time to build your lasagna. Assembly matters here.
Start with sauce on the bottom
Grease your 9×13 dish first. Spread a thin layer of meat sauce on the bottom. This prevents sticking.
Layer your zucchini slices next, slightly overlapping. Press them down gently to compact. Add about one-third of your ricotta mixture in dollops and spread it around. Top with one-third of your meat sauce and sprinkle with mozzarella.
Keep layering
Repeat the same pattern: zucchini, ricotta, meat sauce, mozzarella. Three layers total works well for most dishes.
For the final layer, place your last zucchini slices and load up with the remaining mozzarella. Don’t be stingy with that top cheese layer. It creates the golden crust.
Bake it right
Cover with foil first. This traps moisture so everything cooks evenly without burning the cheese.
Preheat to 375°F. Bake covered for 30-40 minutes, then remove the foil and continue for another 15-20 minutes until the cheese turns golden and bubbly.
Want extra browning? Broil for 1-2 minutes but watch it carefully.
Let it rest
Here’s the important part – let your lasagna sit for 10-15 minutes before cutting. This helps it hold its shape when you serve it.
Storing Your Zucchini Lasagna

Once you’ve made perfect zucchini lasagna, proper storage keeps it tasting great.
Fridge storage works for short term
Let your lasagna cool completely first. Wrap it tight with plastic wrap or foil. Keeps fresh for 3-5 days. Keep your fridge at 40°F or below.
I pre-slice mine before storing. Makes reheating single portions way easier.
Freezing extends the life considerably
Freeze it unbaked for best results. Wrap twice with plastic wrap, then add foil. Label with the date. Good for 3-6 months.
Already baked? Cut into portions first, then freeze in containers. Add extra cheese when reheating to freshen it up.
Reheating without drying out
Oven method works best. Heat to 350°F, add a splash of water or sauce, cover with foil. Bake 30-35 minutes. Remove foil the last 5-10 minutes for crispy top.
Microwave works for single portions. Add water, cover, medium power for 1-2 minutes.
Frozen lasagna needs overnight thawing in the fridge first. Let it sit at room temperature 15-30 minutes before reheating. Remove any liquid with a turkey baster.
Bottom Line
Moisture control makes the difference. Salt your zucchini, use full-fat cheese, let it rest before cutting.
You get 30g protein and just 15g carbs per serving. Pretty good deal.
Takes more prep than regular lasagna. Worth it though.
The techniques work. No more soggy mess.
FAQs
Q1. Is zucchini lasagna suitable for a keto diet?
Yes, zucchini lasagna is keto-friendly. It’s low in carbohydrates and high in fiber, making it an excellent alternative to traditional pasta-based lasagna. When prepared with low-carb sauce, full-fat cheeses, and keto-friendly meats, it fits well within a ketogenic diet plan.
Q2. How do you prevent zucchini lasagna from becoming watery?
To prevent watery zucchini lasagna, salt the zucchini slices and let them rest to draw out moisture. Pat them dry, then grill or roast them to further reduce water content. Use full-fat cheeses and avoid low-fat options that contain more moisture. Also, let the lasagna rest after baking to allow excess liquid to be reabsorbed.
Q3. Should zucchini be cooked before assembling the lasagna?
Yes, it’s recommended to pre-cook zucchini before using it in lasagna. Dehydrate the zucchini slices by cooking them for about 30 minutes until dry. This crucial step helps prevent your lasagna from becoming too soggy. Using a mandolin to slice the zucchini into thin, even planks is also beneficial for optimal texture.
Q4. How many carbs are typically in a serving of zucchini lasagna?
A serving of keto zucchini lasagna typically contains around 15g of carbohydrates. However, the exact carb count can vary depending on the specific recipe and ingredients used. It’s significantly lower in carbs compared to traditional lasagna, making it a great option for those following a low-carb or ketogenic diet.
Q5. Can zucchini lasagna be frozen for later use?
Yes, zucchini lasagna can be frozen. For best results, freeze it unbaked. Assemble the lasagna, wrap it tightly with plastic wrap and aluminum foil, then freeze for up to 3-6 months. When ready to eat, thaw in the refrigerator overnight before baking. Alternatively, you can freeze individual portions of baked lasagna for easy reheating.
