  • Instant Pot


  • 2 tablespoons avocado oil
  • 3 pound chuck roast
  • 1 cup beef broth
  • 2 tablespoons Worcestershire sauce
  • 1 teaspoon rosemary minced, fresh
  • 1 teaspoon salt
  • 1/2 teaspoon black pepper
  • 1 medium onion quartered
  • 4 cloves garlic crushed
  • 16 ounces radishes stem and root ends trimmed off and halved
  • 8 ounces button mushrooms
  • 1 tablespoon fresh minced parsley for garnish


  • Turn the pressure cooker on, press “Sauté”, and wait 2 minutes for the pot to heat up.
  • Add the avocado oil and roast and cook until browned, about 3 to 4 minutes per side, flipping once.
  • Press “Cancel” to stop sautéing.
  • Add the broth, Worcestershire, rosemary, salt, black pepper, onion, and garlic.
  • Turn the pot on Manual, High Pressure for 45 minutes and let it do a natural pressure release.
  • Add the radishes and mushrooms to the pot with the meat and liquid still in it.
  • Turn the pot on Manual, High Pressure for 1 minute and let it do a natural pressure release.
  • Remove the vegetables and roast, arrange them on a serving platter, and sprinkle the parsley on top.
  • Strain the liquid and serve it alongside the roast and vegetables for drizzling on top.


  • You will often have a lot of leftovers so plan to use those within a couple days. 
  • Substitute radishes with other non-starchy vegetables such as broccoli, cauliflower, or Brussels sprouts. You could also use a mix of in-season vegetables for your keto pot roast.
