How to make the perfect zucchini noodles?

As you see, rather than lasagna noodles, i take advantage of zucchini noodles. So, how to make excellent zucchini noodles? Well primarily, you’ll be able to make them using a sharp kitchen knife, a mandolin slicer, or a vegetable peeler. I’ve created this Spinach and Zucchini Lasagna over and over and have made the zucchini noddles using all tools. But, my favorite kitchen tool for making zucchini noodles is that the mandolin slicer. Here’s why:

First, it’s the quickest way to slice zucchini. It’s an ideal way to save time while Also, it creates exceptionally even slices, that is extremely vital to bake the entire lasagna equally. If you’ve got thick and thin zucchini noodles, your lasagna might not cook evenly (some components are going to be cooked and other parts won’t). It’s simple and quick to clean, however after all, you have to be terribly careful since the blades are very sharp. I like to wear my cut-resistant gloves once I use my mandolin because it provides additional protection.

How to perfectly layer Keto Zucchini and Spinach Lasagna:

  • Firstly, spread one cup of the spinach-tomato sauce on the bottom of your casserole dish.
  • Add a second layer of 6 or 7 zucchini slices over the tomato sauce. The amount of zucchini slices you will use depends on the dimensions of the zucchini.
  • Next, place 1/2 cup to 3/4 cup of the ricotta mixture over the zucchini slices.
  • Top the ricotta mixture with mozzarella cheese. Use mozzarella cheese as much as you like, or as little as you like.
  • After that, add another layer of zucchini noodles and tomato sauce. Repeat the layers till all of the ingredients are used.
  • Top with additional mozzarella cheese to feature more flavor to this Spinach and Zucchini Lasagna recipe.
  • In the end, cover the casserole with aluminum foil, and bake the Spinach and Zucchini Lasagna for half-hour. Uncover the dish, and cook for 10-15 additional minutes.
  • After you bake it, take it away from the oven, and let it cool for about 8-10 minutes. Sprinkle with sliced parsley, and serve.
