3 tbsp of salted butter
8 oz of thick-cut bacon or pancetta, diced OR 1 ham bone or ham hock
1 yellow onion, diced
2 stalks of celery, diced
2-3 carrots, peeled and diced
1/2 cup of Sherry
5.5 cups of chicken, garlic and/or ham broth
1 tbsp of Worcestershire sauce
1 tsp of black pepper
1 tsp of dried thyme
1 tsp of oregano
1 lb of dry split green peas, rinsed
2 bay leaves
2 tbsp or 1/4 cup of Boursin or cream cheese, or sour cream (optional)
Add butter to the Instant Pot or Ninja Foodi and hit “Sauté.” Once the butter’s melted and bubbling, add the onions, celery and carrots. Sauté for 5 minutes, stirring occasionally. Add in the bacon, or pancetta, and cook for another 10 minutes.
Add in the Sherry and allow to simmer for another minute. Then, add in the broth, Worcestershire sauce, pepper, thyme, oregano bay leaves and split peas (if using a ham bone/hock, add that in now as well)
Secure the lid and hit “Keep Warm/Cancel” and then hit “Manual” or “Pressure Cook” and cook for 15 minutes at high pressure. Allow a 15 minute natural release when done, followed by a quick release
Stir all the contents in the pot from the bottom up as the split peas will have basically become a purée and will thicken the soup immediately once stirred up. If you want a slightly thinner soup, add in another cup of your choice of broth now.
Stir in the cheese, if using, until melded.
