Ingredients

  • 9 lasagna noodles (regular or no-boil)
  • 2 cups ricotta cheese (or cottage cheese as a budget alternative)
  • 2 cups shredded mozzarella cheese
  • 1/2 cup grated Parmesan cheese
  • 1 (24 oz) jar marinara sauce or homemade tomato sauce
  • 1 (10 oz) package frozen chopped spinach, thawed and drained
  • 1 medium zucchini, thinly sliced
  • 1 medium carrot, grated
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 1 tablespoon olive oil
  • 1 teaspoon dried Italian seasoning
  • Salt and pepper, to taste

Equipment

  • Large pot for boiling noodles
  • Large skillet or frying pan
  • 9×13 inch baking dish
  • Mixing bowls
  • Wooden spoon or spatula
  • Measuring cups and spoons
  • Aluminum foil

Instructions

  1. Preheat your oven to 375°F (190°C). Lightly grease your baking dish with a bit of olive oil or nonstick spray.
  2. Cook the lasagna noodles in a large pot of salted boiling water according to package instructions until al dente. Drain and lay them flat on a clean kitchen towel to prevent sticking.
  3. Sauté the vegetables: Heat olive oil in a skillet over medium heat. Add the chopped onion and garlic, cooking until translucent and fragrant, about 3-4 minutes.
  4. Add the shredded carrot and sliced zucchini to the skillet and cook for another 5 minutes until tender. Stir in the drained spinach and cook for 1-2 minutes more. Season with salt, pepper, and Italian seasoning. Remove from heat.
  5. Mix the cheese filling: In a bowl, combine the ricotta cheese with half of the Parmesan and a pinch of salt and pepper. Stir until smooth.
  6. Assemble the lasagna: Spread about 1/3 cup of marinara sauce on the bottom of the baking dish. Layer 3 noodles over the sauce. Spread half of the ricotta mixture over the noodles, followed by half of the sautéed vegetables, then 1/3 of the remaining sauce, and sprinkle 2/3 cup of mozzarella. Repeat these layers once more: noodles, ricotta, veggies, sauce, mozzarella.
  7. Finish with the last 3 noodles. Spread the remaining sauce over the top and sprinkle with the rest of the mozzarella and Parmesan cheese.
  8. Cover with foil and bake for 30 minutes. Remove the foil and bake uncovered for an additional 10-15 minutes, or until the cheese is bubbly and golden.
  9. Let it rest for 10 minutes before slicing. This helps the lasagna set and makes serving easier.

Tips & Variations

“For extra flavor, add a pinch of red pepper flakes to the tomato sauce or a dash of nutmeg to the ricotta mixture.”

  • Use no-boil noodles to save time—just increase the baking time by 10 minutes and check for tenderness.
  • Add mushrooms or bell peppers to the vegetable mix for more variety and nutrition.
  • Swap ricotta for cottage cheese to reduce cost without losing creaminess.
  • Try vegan cheese alternatives if you want a dairy-free version.
  • Make it gluten-free by using gluten-free lasagna noodles.
