Before you start

Before beginning the recipe, ensure you have washed and diced the carrots into uniform pieces, as this ensures even cooking. Check that your slow cooker insert is clean and placed on a stable, heat-resistant surface.

Rinse the split peas under cold running water in a fine-mesh colander until the water runs clear, which removes excess starch and helps prevent the soup from becoming overly foamy or gummy during the cooking process.

Ingredients at a glance (5)
  • 1 lb smoked sausage, sliced into rounds
  • 2 cups dried split peas, rinsed
  • 2 cups diced carrots
  • 2 bay leaves
  • 6 cups water

Instructions

Layering the ingredients

  1. Assemble the slow cooker
    Place the sliced smoked sausage rounds into the bottom of the slow cooker insert. Add the rinsed split peas and diced carrots on top of the sausage. Distribute the ingredients evenly to ensure consistent cooking throughout the process.
    Look for Ingredients are layered in the slow cooker.
    Tip Always rinse the split peas thoroughly in a colander until the water runs clear before adding them to the cooker.

The slow cooker should be neatly layered with the sausage on the bottom, followed by the peas and carrots.

This arrangement ensures that the ingredients that need the most heat are closest to the heating element while the aromatics and liquids are distributed correctly for optimal flavor extraction during the long cooking cycle.

Adding liquids and seasoning

  1. Add aromatics and liquid
    Tuck the bay leaves into the mixture of peas and carrots. Pour the water over the ingredients until they are fully submerged. Ensure the bay leaves are nestled near the center to infuse their flavor into the soup as it simmers.
    Look for Water covers the ingredients.
    Tip Do not overfill the slow cooker; leave at least an inch of space at the top to prevent it from bubbling over during the long cook time.

The water should completely submerge the dry ingredients, and the bay leaves should be tucked in securely. At this point, the soup will look like a mixture of raw vegetables and water, but the bay leaves will begin to release their subtle, herbal scent even before the heating process begins in earnest.

Simmering to perfection

  1. Cook and serve
    Cover the slow cooker and cook on high for 4 hours or on low for 7 to 8 hours. The soup is finished when the split peas have broken down and the sausage is heated through to at least 160°F (71°C). Remove the bay leaves before serving.
    Look for Soup is thickened and steaming.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip If the soup appears too thick after cooking, stir in an additional half cup of hot water or broth to reach the desired consistency.

The final phase is complete when the soup has transformed into a thick, cohesive mixture. The peas will have lost their shape and turned into a smooth base, the carrots will be soft, and the entire kitchen should be filled with the savory, smoky aroma of the sausage and bay leaves.

Common mistakes

A common mistake is failing to rinse the split peas thoroughly, which can lead to a cloudy or overly starchy soup. Another error is not cutting the carrots into small, uniform pieces, which can result in some carrots being mushy while others remain hard.

Additionally, avoid lifting the lid frequently during the cooking process; every time the lid is removed, heat escapes and the cooking time is extended, which can disrupt the delicate texture of the split peas.

How to tell it’s done

The soup is ready when the split peas have completely softened and thickened the liquid into a creamy, porridge-like consistency.

The carrots should be tender when pierced with a fork, and the smoked sausage should be heated through to an internal temperature of at least 160°F (71°C). If the peas still feel firm or the soup is too watery, continue to cook for another 30 to 60 minutes.
