Set the instant pot to SAUTÉ and when hot, add the bacon. Cook until the bacon is crisp. Remove from the instant pot and set aside to cool. Once cool, break the crisp bacon into small pieces.
Leave a little bacon grease and add the diced onion. Saute for 2 minutes, then press OFF. Add the frozen broccoli, white beans, broth, sea salt, garlic granules, and pepper.
Place the lid on the instant pot. Cook on MANUAL high pressure for 2 minutes. Once the 2 minutes of high-pressure cooking is done, open the valve and allow a quick release.
Add the shredded cheese, and blend with an immersion blender, blender or food processor. You can serve this cheesy soup right topped with the crispy bacon bits!
