Why is my pasta soggy?

I made a baked pasta dish but somehow there's some water pooling at the bottom, I think I didn't thicken the sauce enough but I also need to bulk it up?

Did you let it rest after baking?

nope oops but hopefully if it doesn't work I'll cook it on stovetop like lulu said

What pasta dish mate?

Also, what kind of pasta, how many minutes etc.

Give more details

I think several things went wrong:

Okay I think I overcooked the pasta at first, I should have left it more al dente, I did like 8 minutes because my sibling kept bothering me. I did like a stuffed shells recipe but instead of ricotta I had to use cottage cheese, and spinach + minced mushrooms.

The pasta started steaming as I cooked it and when I looked at the bottom, there was more sauce pooling but the cheese hadn't browned yet

I also didn't let it sit lol

Makes sense then. Al dente means it's hard but chewy.

Both spinach and mushrooms are water. Pure are simple water.

That's why, it was boiling and dropping water.

You should have broiled both spinach and mushrooms before, to drain the water.

Yep problem solved
