Browning the Beef

  • Pat dry the beef with paper towel to remove excess moisture.
  • Turn the pot onto Sauté mode. When the display reads "Hot" add the oil followed by the meat in one layer (see note).
  • Allow the meat to brown for 5 minutes without disturbing it.
  • Flip the meat and brown the other side for 5 more minutes.
  • Remove to a plate and cover with foil. Reserve.

Pressure Cooking

  • Pour in the beef broth to the InstaPot and stir for a minutes or two to loosen browned bits.
  • Add the pepperoncini peppers, ranch mix, au jus mix and butter. Then add the meat back in.
  • Add the meat back into the pot.
  • Cover and seal. Turn off Sauté mode and set to Manual Pressure Cook for 60 minutes.


  • After the cooking cycle finishes, allow for a natural pressure release (about 15 minutes).
  • Manually release any remaining pressure and turn off the Instapot.
  • Remove the meat to a plate and cover with foil.
  • Turn the pot onto Sauté mode again.
  • Mix the cornstarch with 2 tbsp water to make a slurry and add to the pot. Simmer several minutes until thickened slightly.
  • Pull the meat into smaller chunks using two forks or a knife, and add back to the sauce. Serve and enjoy!


  • You’ll need to brown the meat in several batches if you want to double the recipe.
  • If you want to skip the browning steps, then add 10 more minutes to the pressure cooking time.
  • It's helpful to use a fat separator before serving, as the beef can release a lot of fat during cooking.
