Ingredients

  • 1 1/2 cups dried split green 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
  • 6 cups vegetable broth (preferably low sodium)
  • 1 bay leaf
  • 1/2 teaspoon dried thyme
  • Salt and black pepper, to taste
  • 2 tablespoons olive oil
  • Fresh parsley, chopped (for garnish)
  • Optional: 1/4 teaspoon smoked paprika or a pinch of cayenne pepper for a spicy kick

Equipment

  • Slow cooker (4-6 quart capacity recommended)
  • Cutting board and sharp knife
  • Measuring cups and spoons
  • Wooden spoon or spatula for stirring
  • Ladle for serving
  • Blender or immersion blender (optional, for creamy texture)

Instructions

  1. Prepare the vegetables: Chop the onion, garlic, carrots, celery, and potato into uniform pieces to ensure even cooking.
  2. Rinse the split peas: Place the dried peas in a colander and rinse thoroughly under cold water. Remove any debris or damaged peas.
  3. Sauté aromatics (optional): For enhanced flavor, heat olive oil in a skillet over medium heat and sauté the onion and garlic until translucent, about 3-4 minutes. This step is optional but recommended.
  4. Add ingredients to the slow cooker: Transfer the sautéed onion and garlic (or raw if skipping sauté) to the slow cooker. Add the rinsed peas, carrots, celery, potato, vegetable broth, bay leaf, dried thyme, and optional spices.
  5. Set the slow cooker: Cover and cook on low for 7-8 hours or on high for 3-4 hours. The peas should be tender and the vegetables cooked through.
  6. Blend the soup (optional): For a creamier consistency, use an immersion blender directly in the slow cooker or transfer a portion of the soup to a blender. Blend until smooth or to your desired texture.
  7. Season to taste: Remove the bay leaf, then add salt and pepper according to your preference. Stir well.
  8. Serve: Ladle the soup into bowls, garnish with fresh parsley, and drizzle with a bit of olive oil if desired.

Tips & Variations

“If you prefer a chunkier pea soup, skip blending and serve it as is. Adding a splash of lemon juice before serving brightens the flavors wonderfully!”

  • Make it smoky: Add smoked paprika or a dash of liquid smoke for a rich, smoky flavor without meat.
  • Boost protein: Stir in cooked quinoa or add a handful of chopped kale in the last 30 minutes of cooking for extra nutrients.
  • Use frozen peas: If you don’t have dried split peas, frozen green peas can be added in the last hour of cooking for a fresher taste.
  • Spice it up: Include a small diced jalapeño or cayenne pepper for some heat.
  • Make it creamy: Stir in a splash of coconut milk or a dollop of plain yogurt (vegan options available) just before serving.
