Before you start

Before beginning, ensure all ingredients are ready for assembly. Chop the carrots into uniform slices to ensure they cook evenly. Check that the slow cooker is clean and positioned on a stable, heat-resistant surface.

Have the chicken broth measured and ready, and ensure the bacon lardons are cut into consistent sizes if they are not pre-cut.

Gathering all components beforehand allows for a quick and organized assembly process, ensuring the cooking cycle can start promptly without any unnecessary delays.

Ingredients at a glance (5)
  • 6 oz smoked bacon lardons
  • 1 cup green lentils
  • 2 medium carrots, sliced
  • 1 bay leaf
  • 4 cups chicken broth

Instructions

Initial Assembly

  1. Layer the ingredients
    Place the smoked bacon lardons into the bottom of the slow cooker. Add the green lentils and sliced carrots on top of the bacon. Carefully drop the bay leaf into the center of the mixture.
    Look for ensure the lentils and carrots are evenly distributed over the bacon layer
    Tip layering the bacon at the bottom allows the rendered fat to infuse the lentils as they cook

At the end of this phase, the ingredients should be neatly layered in the slow cooker with the bacon at the bottom and the vegetables on top. The bay leaf should be visible near the center. Everything is now ready for the addition of the broth and the start of the heating process.

Slow Cooking

  1. Add liquid and cook
    Pour the chicken broth over the ingredients in the slow cooker. Cover with the lid and set the slow cooker to low. Cook the soup for 4 hours until the lentils are tender and the vegetables are soft.
    Look for the liquid should be hot and bubbling gently
    Tip avoid lifting the lid during the cooking process to maintain a consistent temperature

During the cooking phase, the kitchen will begin to fill with the savory aroma of bacon and herbs. The lentils will gradually absorb the broth, and the carrots will soften. By the end of this phase, the liquid level may have reduced slightly, and the soup should appear thick and hearty.

Final Service

  1. Serve the soup
    Remove the bay leaf before serving. Ladle the hot, rustic lentil soup into bowls and serve immediately while steaming hot.
    Look for the soup should be thickened with a hearty, rustic texture
    Tip a fresh sprinkle of herbs can brighten the earthy flavors just before serving

The soup is ready when the bay leaf is removed and the mixture is well combined. It should look rustic, with the lentils and carrots suspended in a flavorful, slightly thickened broth. The final check ensures the lentils are perfectly cooked and the soup is hot enough to serve immediately.

Common mistakes

A common mistake is using lentils that are too old, which may take significantly longer to soften. Always check the freshness of the dried lentils. Another potential error is overcrowding the slow cooker; ensure there is enough space for the liquid to circulate.

Avoid adding too much salt at the beginning, as the bacon and broth contribute a significant amount of sodium; it is better to season to taste at the very end. Finally, do not lift the lid frequently, as this releases heat and moisture.

How to tell it’s done

The soup is done when the green lentils are tender to the bite but not mushy, and the carrots are easily pierced with a fork. The broth should be rich and slightly thickened from the starches released by the lentils.

There is no specific internal temperature to reach as this is a vegetarian-leaning legume soup, but ensure the contents are steaming hot throughout before serving. The overall texture should be rustic and cohesive, with the bacon pieces fully rendered and flavorful.
