Ingredients

  • 1 1/2 cups dried green split peas, rinsed and sorted
  • 1 medium onion, finely chopped
  • 2 cloves garlic, minced
  • 2 medium carrots, diced
  • 2 celery stalks, diced
  • 1 medium potato, peeled and diced (optional for extra creaminess)
  • 6 cups vegetable broth (low sodium preferred)
  • 1 teaspoon dried thyme
  • 1 teaspoon smoked paprika
  • 1 bay leaf
  • Salt and black pepper, to taste
  • 2 tablespoons olive oil
  • Juice of 1/2 lemon (optional, to brighten flavors)
  • Fresh parsley, chopped for garnish

Equipment

  • Instant Pot or electric pressure cooker
  • Cutting board and knife
  • Measuring cups and spoons
  • Wooden spoon or heat-resistant spatula
  • Ladle for serving
  • Bowl or container for soaking and rinsing split peas

Instructions

  1. Prepare the split peas: Rinse the dried split peas under cold water, removing any debris. Set them aside to drain.
  2. Sauté the aromatics: Turn the Instant Pot to the “Sauté” setting. Add the olive oil, then sauté the chopped onion, garlic, carrots, and celery for about 4-5 minutes until they soften and become fragrant.
  3. Add the spices: Stir in the dried thyme, smoked paprika, and bay leaf. Cook for another minute to release their aroma.
  4. Add split peas and broth: Pour in the rinsed split peas, diced potato (if using), and vegetable broth. Stir well to combine all ingredients.
  5. Pressure cook: Cancel the sauté mode. Secure the Instant Pot lid, ensuring the steam valve is sealed. Set to “Pressure Cook” or “Manual” on high pressure for 15 minutes.
  6. Natural release: Once the cooking time is up, allow the pressure to release naturally for about 15 minutes. After that, carefully open the valve to release any remaining pressure.
  7. Blend or leave chunky: For a creamier soup, use an immersion blender to partially blend the soup directly in the pot. Alternatively, leave it chunky for more texture.
  8. Season and finish: Remove the bay leaf. Stir in lemon juice (if using), and season with salt and black pepper to taste.
  9. Serve: Ladle the soup into bowls, garnish with fresh parsley, and enjoy warm.

Tips & Variations

“For an even heartier meal, add diced tomatoes or chopped kale during the sauté step. A splash of coconut milk can add a lovely creaminess and subtle sweetness.”

  • Make it smoky: Add a teaspoon of liquid smoke or smoked paprika for a deeper flavor profile.
  • Spice it up: Toss in a pinch of cayenne pepper or red chili flakes for some heat.
  • Make it vegan and gluten-free: Use certified gluten-free vegetable broth to accommodate dietary restrictions.
  • Extra protein boost: Stir in cooked quinoa or brown rice before serving.
  • Meal prep friendly: Store leftovers in airtight containers for up to 4 days in the fridge or freeze for up to 3 months.
