Instructions

  1. Preheat the oven to 400°F and grab a 9×12-inch baking dish.
  2. Begin by making the zucchini noodles. Using a sharp knife or mandoline, slice zucchini lengthwise into thin strips, about 1/8 inches in thickness. Once cut, place them on a large plate or sheet pan lined with paper towels, lightly salt each slice on each side, and set them aside while you prepare the other lasagna ingredients.
  3. In a large pot on medium-high heat, warm the olive oil, add the ground beef to the pot and cook, using a wooden spoon or spatula to break it up into small pieces, for 5-6 minutes or until lightly browned on all sides.
  4. Add the diced onion, stir to combine with the ground beef, and cook it for 2-3 minutes until it begins to soften.
  5. Add the diced bell pepper to the pan, stir to incorporate with the beef mixture, and cook for another 2-3 minutes until slightly tender.
  6. Add the minced garlic, dried oregano, salt, and pepper, stir to combine, and cook for 1-2 minutes until fragrant.
  7. Add the crushed tomatoes to the pot and stir to combine with the vegetables. Taste and adjust the seasoning with salt and pepper as needed. Then bring the sauce to a simmer, then reduce it to a simmer and allow it to continue cooking while you prepare the other ingredients.
  8. Next, prepare the ricotta mixture. In a medium bowl, add the ricotta cheese, thawed and chopped spinach, parmesan cheese, egg, nutmeg, salt, and black pepper, and stir until well combined.
  9. Once all of the components are ready, dab the zucchini noodles with a paper towel or tea towel to remove any excess moisture, and then begin to assemble the lasagna.
  10. Add ¼ cup of the meat sauce to the bottom of the baking dish, spreading it out evenly, then layer the bottom of the dish with zucchini noodles, trimming them to fit as needed.
  11. Spread the beef sauce over the first layer of zucchini noodles, reserving  1 ½ cups for the top layer, and spread it out evenly. Then top the sauce with a second layer of zucchini noodles.
  12. Dollop the ricotta mixture over the second layer of zucchini noodles, spreading it out evenly to ensure all of the noodles are covered. Then top the ricotta mixture with a third layer of zucchini noodles.
  13. Spread the reserved meat sauce over the third layer of zucchini noodles, spreading it out evenly across the noodles, and then sprinkle the top with shredded mozzarella cheese.
  14. Transfer the baking dish to the oven, uncovered, and bake for 35-40 minutes until the cheese is bubbly and the top is golden brown.
  15. Once cooked, remove the lasagna from the oven and allow it to cool for 10 minutes, then slice and serve with freshly grated parmesan cheese and basil and slice to serve.
  16. Any leftovers can be cooled and stored in an airtight container in the fridge for up to 5 days or the freezer for up to 3 months.
