Make sure the stainless steel insert is in your Instant Pot. Press the "saute" setting and wait until the display shows HOT.
Add olive oil. Swirl to coat the bottom of the pot.
1 tablespoon olive oil
Add onion, pepper and garlic. Saute for 2 to 3 minutes.
1 medium yellow onion, 1 small green bell pepper, 3 garlic cloves
Add Italian seasoning and paprika. Stir in well and cook for 1 minute.
2 teaspoons Italian seasoning, ½ teaspoon ground paprika
Add ground beef and cook breaking it apart with a wooden spoon. If you are using fatty beef, you may need to drain the grease. The best way to do this is to push the beef onto one side in the pot and scoop out the grease with a ladle.
1 lb lean ground beef
Add salt and pepper and stir in.
½ teaspoon salt, ½ teaspoon black pepper
Press "cancel/off" button.
Add 1 cup of beef stock and deglaze the bottom of the pot, by scraping any cooked on bits with a wooden spoon.
2 cups beef stock
Add remaining beef stock and water.
3 cups water
Add corn, celery and carrots. Stir in.
2 medium carrots, 2 celery ribs, 1 cup whole kernel corn
Add tomato sauce and crushed tomatoes. Place the Bay leaf on top. Do not stir.
1 ½ cups crushed tomatoes, 8 oz can tomato sauce, 1 Bay leaf
Close the lid and set valve to sealing position (the newer IP models do it on their own).
Press the "manual" or "pressure cook" setting and make sure the Instant Pot is set to cook on HIGH pressure.
Set timer to 7 minutes.
The Instant Pot will beep and start coming to pressure. This can take 12 to 15 minutes. Remember, there is a lot of food in the Instant Pot.
Once the timer is done, press "cancel/off" button and wait 5 minutes. Then switch the valve to "venting" position to release any remaining pressure.
Carefully open the lid away from your face. The soup will be bubbling.
Stir in and let the soup sit for 10 minutes to cool.
Notes
Please note, that the nutrition value can vary depending on what product you use. The information below is an estimate.
use at least 80% lean ground beef; you won't have to drain the grease. You can also use ground turkey, that is known for very low fat content.
