Before you start

Before starting, ensure all vegetables are washed and diced into uniform half-inch pieces. This uniformity is crucial for ensuring that the carrots and onions cook through at the same rate.

Have all dry seasonings measured out and ready, and ensure the chicken broth and canned tomatoes are at room temperature to avoid a drastic drop in the slow cooker's initial temperature.

Ingredients at a glance (8)
  • 1 lb smoked sausage, sliced into coins
  • 1 cup dry brown lentils, rinsed
  • 2 cups diced carrots
  • 1 cup diced onion
  • 1 tsp smoked paprika
  • 1 tsp garlic powder
  • 4 cups chicken broth
  • 1 can (14.5 oz) crushed tomatoes

Instructions

Assembly of ingredients

  1. Layering the ingredients
    Place the sliced smoked sausage coins into the bottom of the slow cooker. Scatter the dry brown lentils, diced carrots, and diced onion evenly over the sausage layer to ensure balanced cooking.
    Look for The bottom of the slow cooker should be covered with the sausage slices.
    Tip Ensure the vegetables are cut into uniform pieces for even cooking.

The slow cooker should be neatly layered with the sausage coins at the bottom, topped by the lentils and vegetables.

The colors should be vibrant, with the orange of the carrots and the deep brown of the lentils providing a clear visual contrast against the sausage.

Adding seasonings and liquid

  1. Seasoning and liquids
    Sprinkle the smoked paprika and garlic powder over the lentil and vegetable mixture. Pour the chicken broth and crushed tomatoes over the top, ensuring all ingredients are well moistened.
    Look for The liquid should just cover the top of the lentils and vegetables.
    Tip Adding the spices before the liquid helps distribute the flavor more evenly.

The broth and crushed tomatoes should submerge the solid ingredients, creating a consistent base. The spices should be distributed so they do not clump together, ensuring the flavors permeate the entire volume of the soup as it begins to heat up.

Slow cooking process

  1. Slow cooking
    Cover the slow cooker and cook on low for 4 hours until the lentils are tender and the flavors have melded. Once finished, check the internal temperature of the sausage to ensure it reaches at least 160°F (71°C) before serving.
    Look for The lentils should be soft and the soup thickened.
    Safe temperature 160°F (71°C) internal temperature (ground meat)
    Tip Stir the soup gently before serving to incorporate the tomato base.

The soup should emit a savory, smoky aroma, indicating that the sausage flavors have fully infused the broth. The lentils will have absorbed most of the liquid and expanded, creating a thick, hearty consistency that is uniform throughout the crock.

Common mistakes

A common mistake is adding salt too early, which can sometimes toughen the skins of the lentils, though this is less of an issue in a slow cooker.

Another error is neglecting to rinse the lentils, which can introduce grit or unwanted starchiness to the soup. Finally, avoid opening the slow cooker lid frequently, as each lift releases heat and extends the required cooking time significantly.

How to tell it’s done

The soup is ready when the lentils are tender and creamy to the bite, not mushy. The carrots should be soft enough to be easily pierced with a fork.

Since the smoked sausage is pre-cooked, the primary goal is to ensure it is heated through to an internal temperature of 160°F (71°C). The final consistency should be thick and stew-like, with the broth clinging to the lentils.
