Update: 3.5 year old beef roast was delicious

This was a beef roast that was vacuum sealed and frozen for over 3.5 years, I asked the community and most people said it was totally fine as long as it didn't smell funky once thawed.

Roasted at 425 for 15 minutes then 325 for an hour was perfection. Would recommend dry brining as it wasn't that salty inside but still juicy and tender.
