Turn on the sauté function on your Instant Pot. Add a little cooking spray or olive oil, then sauté the diced onion and minced garlic for about 2-3 minutes until they become fragrant.
Add the chopped cabbage, sliced carrots, chopped celery, diced tomatoes (with their juice), dried thyme, dried oregano, paprika, salt, and pepper to the Instant Pot. Stir well.
Pour in the vegetable broth and give everything one final stir.
Close the Instant Pot lid, set the valve to sealing, and cook on manual/high pressure for 5 minutes.
Once the cooking cycle is complete, allow for a natural release for about 10 minutes before carefully releasing any remaining pressure.
Taste the soup and adjust the seasonings as needed. Garnish with chopped fresh parsley if desired.
