Ingredients
- 12 lasagna noodles
- 3½ cups tomato sauce
- 4-5 zucchini (sliced lengthwise into ¼” slices)
- 1⅓ cups grated parmesan cheese
- 1¾ cups shredded mozzarella cheese
- 1 cup ricotta cheese
- 7-8 slices fresh mozzarella cheese
Instructions
- Preheat your oven to 375°F (190°C). Cook the lasagna noodles according to package directions until al dente. Drain and set aside.
- While noodles cook, prepare the zucchini slices. Pat them dry with paper towels to remove excess moisture.
- In a medium bowl, mix the ricotta cheese with 1 cup of the grated parmesan cheese.
- Spread ½ cup of tomato sauce in the bottom of a 9×13 inch baking dish.
- Place a layer of 3 lasagna noodles over the sauce.
- Spread about ⅓ of the ricotta-parmesan mixture over the noodles.
- Arrange a single layer of zucchini slices over the ricotta mixture.
- Sprinkle ½ cup of shredded mozzarella over the zucchini, then spoon ¾ cup of tomato sauce over the cheese.
- Repeat the layering process (noodles, ricotta mixture, zucchini, shredded mozzarella, sauce) two more times.
- For the final top layer, place the last 3 noodles, cover with the remaining tomato sauce, and arrange the slices of fresh mozzarella cheese evenly on top. Sprinkle with the remaining ⅓ cup grated parmesan cheese.
- Cover the baking dish with aluminum foil and bake for 45 minutes.
- Remove the foil and bake for an additional 15 minutes, or until the cheese on top is golden and bubbly. Let the lasagna rest for 15 minutes before slicing and serving.
Variations
- Grilled Zucchini: Grill the zucchini slices before assembling for a smoky flavor.
- No-Boil Noodles: Use oven-ready lasagna noodles to skip the pre-cooking step.
- Layered Casserole: For a faster assembly, chop the zucchini into half-moons and mix all components together in the dish before baking.
- Individual Servings: Assemble the lasagna in smaller, personal-sized baking dishes for a fun presentation.
Tips for Success
- Salting and patting dry the zucchini slices is crucial to prevent a watery lasagna.
- Letting the lasagna rest after baking allows the layers to set, making it much easier to slice cleanly.
- Use a sharp knife or mandoline to ensure your zucchini slices are uniformly thin.
- For golden cheese, broil the lasagna for the final 2-3 minutes after baking.
Storage & Reheating
Leftovers can be stored in an airtight container in the refrigerator for up to 4 days. Reheat individual portions in the microwave or reheat larger portions, covered with foil, in a 350°F oven until warmed through.
FAQ
Can I make this lasagna ahead of time?
Yes, assemble it completely, cover tightly, and refrigerate for up to 24 hours before baking. You may need to add 5-10 minutes to the baking time.
Do I have to peel the zucchini?
No, the skin is tender and adds color and nutrients. Just wash them well.
My lasagna is watery, what went wrong?
This is usually from not removing enough moisture from the zucchini. Always pat the slices very dry with paper towels before assembling.
Can I freeze this lasagna?
Absolutely. Bake it, let it cool completely, then wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge and reheat covered in a 350°F oven.
Can I use only zucchini and no noodles?
For a strictly low-carb version, you can, but you will need to use more zucchini and layer them more densely to hold the structure.
What can I do if my ricotta mixture is too thick?
A splash of milk or a beaten egg can help loosen the ricotta mixture for easier spreading.
