Heat a bottom heavy sauce pan to medium heat and add in the broth. Allow the stock to reduce by half.
While the broth reduces, pulse the chia seeds in a coffee grinder until ground. Set aside.
Remove reduced broth from heat and add in the ground up chia seeds, heavy cream, garlic powder, salt and pepper, and whisk to combine.
Let it sit for 5-10 minutes to allow it to thicken.
Add in the butter and Parmesan and whisk to combine. If the mixture is no longer hot, return to stove top over low heat and allow butter and cheese to melt down.
