Six to 12 hours before you want to make the soup, soak the split peas. Soaking helps reduces the phytic acid in the legume, making them easier on digestion. You’ll notice around the 10 hour mark that the peas will have the start of a little sprouted “tail.” Sprouting legumes allows the nutrients in the bean more readily available to absorb. Soak for at least 6 hours and no more than 12.
When you are ready to make the soup, turn your Instant Pot on to “Saute,” melt the cooking fat (ghee and bacon grease), and add the onion, carrots, and celery with a big pinch sea salt. Saute for about 10 minutes until the veggies are very soft and sweet. Slow down and don’t skip this step! This is flavor!
Add the garlic and smoked paprika and Saute for 1 minute, then turn the Instant Pot to “Off/Cancel.”
Drain and rinse your soaked split peas, add them into the Instant Pot along with the bone broth and bay leaf, and stir to combine.
Put the lid on your Instant Pot, turn the valve to closed, turn your Instant Pot on to “Soup,” and bring time down to 10 minutes. The Instant Pot will take about 10 minutes to come to pressure before counting down the 10 minutes. When the timer beeps that the 10 minutes of pressure cooking is done, turn the Instant Pot off, and leave the Instant Pot alone for 5 minutes. This naturally will let some of the pressure in the Instant Pot release and finishes the cooking process without overcooking the split peas. Release the rest of the pressure after 5 minutes, and take the lid off the Instant Pot. Remove the bay leaf.
Scoop out 2-3 cups of the soup to a small mixing bowl, and blend with an immersion blender (you could use a regular blender), and then return the blended portion of soup back into the pot with the rest of the soup (it makes the broth nice and creamy!). Stir to combine, and sea salt/pepper your soup to your taste. The split pea soup will thicken a bit more as the soup cools since the peas continue to absorb liquid. You could alternatively blend the entire soup – my toddlers enjoyed using a stainless steel straw to drink their soup this way!
Drizzle olive oil and/or splash raw cream or coconut cream into each bowl of split pea soup to garnish if you wish.
