First, put your Instant Pot on Sauté (high) and add three tablespoons of vegetable or
olive oil.
Next, add your beef and 1 tbsp. seasoning of choice to your meat. Place all of your meat into the Instant Pot. Once your pot starts accumulating the juice from your meat proceed with the rest of the recipe. (No browning required) The 1 cup of "juice" that your pot accumulates in this step is the liquid that it will use to pressure cook your meat.
Then sprinkle your packets of Ranch and Au Jus on top of your meat. Place the Peperoncini Peppers and sliced butter on top of the meat.
Close the lid and turn the steam release valve to the “sealing” position.
Next, press the pressure cook button. Then press pressure level button until
high is selected. Set timer for 45 minutes. **Please note- If your Instant Pot is still on sauté mode you will need to press “Cancel” then “Pressure Cook”.
After the timer has completed allow your Instant Pot to naturally release the pressure. This should take about 20 minutes.
Finally, serve over rice or mashed potatoes and enjoy!
