Unfortunately when you bake freeze then cook again the crust will not be new and will sizzle like it would if it was only frozen and then baked once.

When you cook something, you fundamentally alter it. Proteins, fats, starches, and sugars change in one way or another. Starches like pasta absorb liquid. Proteins denature fats, they liquefy and sugars caramelize.

Giving someone a baked and then frozen lasagna is like giving them leftovers. Whereas giving them a raw lasagna is giving them a fresh meal. Your effort, baking it, is the same, but the result is very different!
