How To Dry Out Zucchini Noodles
- Begin by slicing 1 small zucchini into thin strips. You can do this either by hand with a sharp knife or by using a mandoline.
- Lay the zucchini strips on a long cutting board or a tray and lightly sprinkle salt over them. Zucchini contains a lot of water. When you salt the zucchini, the salt pulls the water out of the vegetable and also lightly seasons it at the same time.
- Let the zucchini strips sit undisturbed for about 10 minutes. After this time, dry the zucchini well with a paper towel.
How To Make Lasagna
- Heat the oven: Preheat the oven to 350 degrees F (177 C).
- Brown the meat: Cook the meat, onions, garlic, and seasonings in a medium sized skillet.
- Make the sauce: Add tomato sauce and simmer.
- Mix the cheeses: In a small bowl, mix together the ricotta and some of the parmesan cheese.
Pro Tip: Make this a vegetarian lasagna by leaving out the meat.
How To Assemble Zucchini Lasagna
- Spread a few spoonfuls of the meat sauce into the bottom of the dish. Then, line the bottom of the dish with zucchini noodles. Layer with 1/2 of the meat mixture, then 1/2 of the ricotta mixture, and top with shredded mozzarella cheese. Repeat by adding another layer of zucchini strips, and the remainder of the meat sauce, ricotta mixture, and mozzarella cheese. Finish with the final layer of zucchini strips and top with the remaining tomato sauce, mozzarella cheese and parmesan cheese.
- Place the baking dish on a baking sheet and bake in a 350 degree F oven for 30 minutes or until the top layer of cheese has melted.
- The size of your baking dish will determine how many layers you are able to add. For this zucchini lasagna recipe, I use a 5-inch baking dish and I can get one layer of filling between the zucchini noodles.
- The size of the baking dish I use holds 16-ounces. Its measurements are: 5-inches x 5-inches and is 1 3/4-inches tall.
- You can also use a 8 1/2 x 4 1/2-inch loaf pan for this recipe. With a loaf pan, you will be able to add an additional layer.
- This recipe makes one large serving or can be the perfect sized meal for two people if served with a salad or other side dish.
