How do you prevent mushy frozen meals?

Hey everyone, I recently switched to a busier job and meal prep has become essential for easy dinners on hectic nights. My main problem is meals end up mushy after thawing and reheating.

I don’t think it’s my freezer it’s new. My storage setup is solid too. I bought some silicone bags in bulk from Alibaba a few months ago and I also grabbed some containers from Amazon last month. So the issue isn’t the packaging it’s probably my cooking and storage process itself.

A friend suggested slightly undercooking veggies and proteins before freezing so they don’t get soggy later. Curious if anyone has tips on portioning, freezing methods, or reheating hacks to keep meals tasting fresh.
