Remove beef from the fridge 2 hours before cooking to let it come to room temperature. This helps it cook evenly.
Preheat oven to 500° and line a small sheet tray with parchment paper.
In a small bowl, combine the salt, pepper, garlic powder, onion powder, thyme, rosemary and paprika.
Drizzle the avocado oil over the roast and then sprinkle the seasoning on top. Coat the meat well, covering all the sides well. Place on the sheet tray and bake for 15 minutes.
Reduce to 300° bake for 40 more minutes or until the internal temperature is 135°-145° or to desired temperature. Add time in 5-10 min increments as needed
Let the meat rest 20-30 minutes before slicing.
Store covered in the fridge for up to a week.
This is easy to slice when cold if you're using it for sandwiches.
