  12. Finish with the remaining sauce and sprinkle mozzarella evenly on top.

  14. Remove the foil and bake for another 15–20 minutes until golden and bubbly.
  15. Let the lasagna rest for 15 minutes before slicing and serving.

Notes

  • Drain excess moisture from the mushrooms and spinach to prevent a watery lasagna.
  • Let the lasagna rest for at least 15 minutes before slicing for cleaner layers.
  • Freshly grated Parmesan and mozzarella provide the best flavor and melting texture.
