Frequently Asked Questions
Can I use a different vegetable instead of zucchini?
Yes, thinly sliced eggplant works well, but it must be salted and drained, then roasted or grilled to remove moisture, just like the zucchini. Some people use thin slices of deli chicken or turkey as the “noodles” for a zero-carb option; this creates a very different, meatier dish but is delicious. Cabbage leaves, blanched until pliable, can also be used for a cabbage roll-style lasagna. The key with any vegetable substitute is to remove as much water as possible before layering.
Is this lasagna keto-friendly?
Yes, this recipe is very low in net carbohydrates, especially if you use a sugar-free marinara sauce. Each serving contains roughly 6–8 grams of net carbs, depending on the exact ingredients and portion size. It’s an excellent keto dinner option that’s high in protein and healthy fats. The zucchini, ricotta, and sauce all contribute small amounts of carbs, but they are well within keto guidelines when portioned appropriately.
Why is my lasagna watery despite roasting the zucchini?
This can happen if the sauce was too thin or too much sauce was used, if the zucchini slices were too thick and retained moisture, or if the lasagna was cut before it had rested. In the future, reduce your sauce on the stovetop before using, slice the zucchini very thin (⅛ inch), and always allow the full 10–15 minute resting time. You can also sprinkle a tablespoon of almond flour or grated Parmesan between the layers to absorb any excess moisture.
Can I make this dairy-free?
You can substitute the ricotta with a dairy-free ricotta alternative (made from almonds or tofu), use plant-based mozzarella shreds, and replace the Parmesan with a dairy-free version or nutritional yeast. The egg is still needed to bind the filling. The texture and flavor will be different, but it can still be a satisfying dish. The sauce should also be dairy-free (most marinara is).
Can I use ground chicken instead of shredded?
Yes. Brown 1 pound of ground chicken or turkey in a skillet with olive oil, garlic, and Italian seasoning until fully cooked. Drain any liquid and let it cool slightly before adding to the ricotta mixture. The texture will be a bit more crumbly, similar to a traditional meat lasagna. Both versions are delicious.

Servings:

Ingredients
- 3–4 medium zucchini, sliced lengthwise into ⅛–¼ inch planks
- Olive oil, for brushing
- Salt and black pepper
- 2 cups shredded cooked chicken (rotisserie works great)
- 15 oz whole-milk ricotta cheese
- 1 large egg
- ½ cup grated Parmesan cheese
- 2 garlic cloves, minced
- 1 teaspoon Italian seasoning
- 1½ cups low-carb marinara sauce (sugar-free)
- 2 cups shredded low-moisture mozzarella cheese
- Fresh basil or parsley, for garnish (optional)
Instructions
- Preheat oven to 400°F (200°C). Arrange zucchini planks on parchment-lined baking sheets. Brush lightly with olive oil, season with salt and pepper, and roast for 10–12 minutes, flipping once, until just tender and moisture has evaporated. Remove and reduce oven to 375°F (190°C).
- Make the filling: In a bowl, combine ricotta, egg, Parmesan, minced garlic, Italian seasoning, salt, and pepper. Stir until smooth. Fold in shredded chicken.
- Assemble in an 8×8-inch dish: Spread a thin layer of marinara on the bottom. Add a layer of roasted zucchini, half the chicken-ricotta mixture, a sprinkle of mozzarella, and some sauce. Repeat layers, ending with zucchini, remaining sauce, and a generous mozzarella top.
- Bake for 30–35 minutes, until bubbly and golden. Broil for 2–3 minutes at the end if a crispier top is desired.
- Rest for 10–15 minutes before slicing. Garnish with fresh basil or parsley and serve warm.
Notes
- Roasting the zucchini before layering is essential to remove moisture and avoid a watery lasagna.
- For a dairy-free version, use dairy-free ricotta, mozzarella, and Parmesan alternatives.
- Leftovers keep in the fridge for up to 4 days and freeze well for up to 3 months.
- To make it even heartier, add sautéed spinach, mushrooms, or browned ground turkey to the filling.
