Preparation

Chef’s notes

Use vegetables you love; options include mushrooms, fennel, peppers, zucchini, eggplant, or broccoli.
For a cheesier lasagna, increase mozzarella to 1 1/2 pounds.
Frozen lasagna is perfect for future meals, so consider making two batches.
If you dislike the texture of baked ricotta, consider mixing with heavy cream to keep it creamy.
