Turn the Instant Pot on to Saute. Once it heats up, fry bacon until crisp, then remove to a plate. Drain all but a tablespoon of bacon grease.
Add onion to pot and cook for a few minutes, adding the garlic for another minute of cooking.
Next, add the sausage and brown it, crumbling as it cooks. If using my sausage recipe, now is the time to add the spice mix. Stir well one more time.
Sprinkle flour over onion and garlic in pot, then stir to combine.
Pour in chicken stock, then add in potatoes, and bacon. Put the lid on the instant pot. Seal, and cook on high pressure for 5 minutes.
After the cooking is complete, allow the pot to do a natural pressure release for 15 minutes.
Then carefully open the instant pot lid away from you.
Add in the kale and let it wilt for a couple minutes. Finally add in the half and half.
Taste and season with salt, pepper and red pepper flakes if desired.
