Make the Gravy
Combine 3 tablespoons cornstarch with 3 tablespoons COLD water. Whisk until well-combined and smooth.
Bring the meat juices to a boil. Slowly add the cornstarch mixture to the boiling liquid, stirring continuously. Once it's all added, reduce to a simmer.
Simmer until desired thickness is reached, then transfer to a serving container and serve.

Instant Pot
Turn the Instant Pot to Sauté Mode.
Brown the roast in olive oil for 5 minutes on each side, remove and set aside.
Deglaze the pan with 1 cup of low sodium beef broth or water. Run a silicone spatula along the bottom to release any brown bits.
Add the Roast back and sprinkle with the Au Jus and Ranch Dressing Mix. Top with cubed butter and pepperoncini peppers.
Set to Meat Mode and cook for 45 minutes. (Ensure the pressure valve is closed.)
Let the pressure release naturally for 5-10 minutes, then flip the quick release valve.
Remove the roast and cover it with foil to keep it warm.
Set the Instant Pot to Sautee mode and make gravy as noted in recipe instructions.
