Tips:
- Drain the spinach thoroughly before using it in the filling.
- Use no-cook noodles or drain and dry boiled noodles before layering.
- Let the lasagna cool slightly before cutting to prevent it from becoming runny.
- For a browned top, broil the lasagna for a minute or two before removing it from the oven.
Variations:
- Add additional vegetables like mushrooms, squash, or broccoli.
- Make a spicy version by adding red pepper flakes.
- For a low-carb option, use eggplant or spaghetti squash as a base.
