Description

A crowd‑pleasing, vegetarian spinach ricotta lasagna layered with creamy cheese and tomato sauce—perfect for weeknight dinners or special gatherings.


Ingredients

  • 912 lasagna sheets
  • 4 cups frozen spinach (thawed, drained, squeezed dry)
  • 15 oz (425 g) ricotta cheese
  • 2 cups (200 g) shredded mozzarella cheese, divided
  • 1 cup (100 g) grated Parmesan cheese, divided
  • 3 cups (720 ml) marinara sauce (homemade or store‑bought)
  • Salt & pepper to taste
  • 1 tsp dried Italian seasoning (optional)


Instructions

  1. Preheat oven to 400 °F (200 °C).
  2. Prepare lasagna sheets according to package instructions (boil or use no‑boil sheets).
  3. In a bowl, combine drained spinach, ricotta, ¾ cup Parmesan, salt, pepper, and Italian seasoning.
  4. Spread ½ cup marinara along the bottom of a 9×13‑inch baking dish. Arrange a layer of lasagna sheets over sauce.
  5. Top noodles with ½ cup marinara, one‑quarter of the spinach‑ricotta mixture, and a sprinkle of mozzarella.
  6. Repeat layers (noodles → sauce → cheese mixture → mozzarella) two more times.
  7. Finish with a top layer of noodles, remaining sauce, mozzarella, and the rest of the Parmesan.
  8. Bake for 25–30 minutes until bubbly and the cheese is golden.
  9. Let rest for 10 minutes before slicing to help it set.

Notes

  • Ensure the spinach is well‑drained to avoid a watery lasagna.
  • For deeper flavor, use homemade marinara sauce.
  • You can assemble it ahead of time and refrigerate before baking.
  • If using fresh mozzarella, drain it on paper towels to remove extra moisture.
