Ingredients

  • 2 cups dried green split peas, rinsed and sorted
  • 1 large yellow onion, diced
  • 3 medium carrots, peeled and diced
  • 3 celery stalks, diced
  • 4 cloves garlic, minced
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried thyme
  • 1 teaspoon dried oregano
  • 1 bay leaf
  • 8 cups vegetable broth
  • 2 tablespoons olive oil
  • Salt and freshly ground black pepper, to taste
  • Optional: 1 tablespoon lemon juice for brightness
  • Optional garnish: chopped fresh parsley or green onions

Equipment

  • 8 quart Instant Pot or any electric pressure cooker
  • Measuring cups and spoons
  • Sharp knife and cutting board
  • Wooden spoon or heat-resistant spatula
  • Ladle for serving
  • Blender or immersion blender (optional, for creamier texture)

Instructions

  1. Prepare the vegetables: Dice the onion, carrots, and celery into small, even pieces to ensure they cook evenly.
  2. Sauté the aromatics: Set your Instant Pot to the ‘Sauté’ function. Add the olive oil, then the diced onion, carrots, and celery. Cook for about 5 minutes until the onions become translucent and the vegetables soften slightly.
  3. Add garlic and spices: Stir in the minced garlic, smoked paprika, dried thyme, and oregano. Sauté for another minute until fragrant.
  4. Add split peas and broth: Pour in the rinsed split peas and vegetable broth. Add the bay leaf and stir to combine.
  5. Pressure cook: Secure the lid on the Instant Pot and set the valve to ‘Sealing.’ Cook on ‘Manual’ or ‘Pressure Cook’ high pressure for 15 minutes.
  6. Natural release: Once the cooking cycle is complete, allow the pressure to release naturally for about 15 minutes, then carefully switch the valve to ‘Venting’ to release any remaining pressure.
  7. Season and blend (optional): Remove the bay leaf. Taste the soup and add salt and pepper as needed. For a creamier texture, use an immersion blender to puree part or all of the soup, or transfer a few cups to a blender and blend until smooth.
  8. Add finishing touches: Stir in lemon juice if using, which adds a lovely brightness to the soup. Garnish with fresh parsley or green onions before serving.

Tips & Variations

“For extra depth of flavor, consider adding a smoked paprika powder or a splash of soy sauce during cooking. If you want a chunkier soup, skip blending and leave the peas whole.”

  • Make it vegan and allergy-friendly: This soup is naturally vegan and gluten-free. Just be sure your vegetable broth contains no animal products or gluten.
  • Add greens: Stir in a few handfuls of chopped kale or spinach during the last 5 minutes of cooking for added nutrition.
  • Boost protein: Add cubed firm tofu or cooked chickpeas after cooking for an extra protein boost.
  • Spice it up: For a little heat, add a pinch of cayenne pepper or a teaspoon of your favorite hot sauce.
  • Storage: This soup keeps well in the refrigerator for up to 5 days and freezes beautifully for up to 3 months.
