Split Pea and Kale Soup (Instant Pot)
This protein-rich split pea soup combines green split peas’s earthiness with fresh kale’s nutritious benefits. Using just five ingredients, this minimalist approach delivers maximum flavor while keeping shopping and prep time to a minimum.
The Instant Pot method transforms what traditionally takes hours on the stovetop into a quick and efficient meal prep solution. Each serving provides 18g of protein, making it an excellent plant-based lunch option that will satisfy you throughout the afternoon.
- 2 cups green split peas
- 1 large onion, diced
- 4 cups vegetable broth
- 1 bunch of kale, stems removed and roughly chopped
- 2 teaspoons salt
Add split peas, diced onion, and vegetable broth to the Instant Pot. Close the lid and set valve to sealing position. Cook on high pressure for 15 minutes, then allow for natural pressure release for 10 minutes. After releasing the remaining pressure, open the lid and stir in chopped kale and salt. Let stand for 2-3 minutes until kale wilts, then serve.
For best results, rinse split peas thoroughly before cooking to remove any debris. If the soup becomes too thick after cooking, add warm water or additional broth to achieve the desired consistency. The soup can be stored in an airtight container in the refrigerator for up to 5 days or frozen for up to 3 months.

For best results, don’t skip rinsing the lentils as this removes excess starch and prevents the soup from becoming too thick. If the soup thickens too much upon standing, thin it with additional vegetable broth or water. For meal prep, portion the soup into individual containers without the cilantro garnish, which should be added fresh when serving. The soup can be reheated on the stovetop or in the microwave.
