Drain sauerkraut in a colander placed in the sink. (If your sauerkraut doesn't seem that chopped up, I used kitchen shears to chop it up a bit more.

Cut up the corned beef into medium-sized cubes (or smaller if you prefer.)

Set Instant Pot to SAUTE, MEDIUM HEAT.

Heat the olive oil, then add the chopped onion and cook about 4-5 minutes; add minced garlic and cook 2-3 minutes more.

Then add chicken broth, beef broth, dried thyme, diced tomatoes with juice, drained sauerkraut, diced corned beef, Worcestershire Sauce, bay leaves, and chopped parsley.

Set Instant Pot to MANUAL, HIGH PRESSURE, 5 minutes.

When the cooking time is up, let the Instant Pot NATURAL RELEASE for 10 minutes; then release the rest of the pressure.

Stir in balsamic vinegar and Monkfruit sweetener, season to taste with lots of fresh ground black pepper and serve hot.

We ate it with coarsely-grated Parmesan Cheese sprinkled on top and a drizzle of extra balsamic vinegar.

You will need about one cup more beef broth to make this on the stove.

Chop one onion to make 1 cups chopped onion.

Heat olive oil in a heavy soup pot, add onion and saute 4-5 minutes, or until the onions are starting to get lightly browned.

Add minced garlic and saute 2-3 minutes more.

Add chicken broth, beef broth, diced tomatoes with juice, Worcestershire sauce, chopped parsley, and bay leaves and let soup simmer on low for 30 minutes.

While soup simmers, drain the sauerkraut in a colander placed in the sink.

Cut corned beef into medium-sized cubes

When sauerkraut is drained, coarsely chop with kitchen scissors or a large chef’s knife.

After 30 minutes, add sauerkraut, corned beef, and sweetener to the soup.

Stir soup to see if it’s getting too thick, and add a little water if needed. (You probably won't need the water if you add the extra cup of beef stock.)

Let soup simmer 15 minutes more.

After 15 minutes, stir in 1 T balsamic vinegar and season to taste with fresh ground black pepper.

Serve hot, sprinkled with coarsely-grated Parmesan or Swiss cheese and an extra drizzle of balsamic vinegar if desired.
