Pound or tenderize the round steak if desired. This is not necessary when using the pressure cooker. Combine flour, salt, black pepper, onion & garlic powder. Dredge the steak
Prepare and measure all the other ingredients.
Turn the Ninja Foodi or Instant Pot on sear/sauté on high. Add 2 Tablespoons of olive oil or oil of choice.
When the oil is hot, add 3-4 of the flour coated round steak to the bottom to sear. Let it cook about 3 minutes and flip and cook an additional 2 minutes. If you are making 3 pounds of round steak you may need to cook in batches.
Deglaze the inner pot with the beef broth and make sure to scrape the bottom to loosen any brown bits that may be stuck on the bottom. Add the can of fire roasted tomatoes with the juice, the Worcestershire sauce and red wine vinegar. Add the steak back in if you removed it. Add the onion and 2 carrots. If you are only cooking the Swiss steak without potatoes and additional carrots, put the pressure lid on and set the time to 25 minutes. When the time is up, allow the pot to natural release for 10 minutes and then release the remaining pressure and remove the lid. Thicken the sauce with tomato paste if desired. Serve & Enjoy! If you are making the potatoes and extra carrots proceed to the next step.
Garlic Smashed Potatoes & Extra Carrots
Place the reversible rack on low or your trivet on top of the steak. Place the whole and unpeeled potatoes on the rack. Cut the top off of a bulb of garlic and set it on the rack. Put the pressure lid on and turn the valve to seal. Set the pressure on high for 13 minutes. When the time is up do an immediate release.
Open the lid and add in the extra carrots. Put the pressure lid on and turn the valve to seal. Set the pressure on high for 5-7 minutes. 7 minutes will be a softer carrot. When the time is up, allow the pot to natural release for 10 minutes. Release the remaining pressure and open the lid.
Remove the whole potatoes and place them in a bowl for mashing. Remove the garlic and carrots and set aside. Remove the rack and add in the tomato paste for thickening. Turn the sear/sauté on high if needed to reduce the sauce.
Squeeze the garlic cloves out of the bulb of garlic into the bowl of potatoes. Add the butter. Smash them and add cream if desired. Salt and pepper to taste.
