Equipment

  • Medium saucepan
  • Wooden spoon
  • Large saucepan with lid
  • Rimmed baking sheet
  • Small bowl
  • Tongs or slotted spoon
  • Plate for serving

Ingredients

  • 2 tablespoons olive oil
  • 1 large onion chopped
  • 4 slices smoky bacon cut into small pieces
  • 1 medium carrot sliced
  • 1 celery stick sliced
  • 1 clove garlic crushed
  • 1 14 oz can crushed tomatoes
  • 1 cup red lentils rinsed (see note)
  • 1 bay leaf
  • ½ teaspoon dried thyme
  • 4 cups chicken stock 1 quart
  • Salt & pepper to taste

Instructions

  • Heat the Oil: Place a large saucepan over medium heat and add 2 tablespoons olive oil.
  • Cook the Onion: Add the chopped onion and sauté for about 2 minutes until golden brown.
  • Add the Bacon: Stir in the bacon pieces and cook for about 5 minutes, until the fat starts to render and the bacon is browned. Move the onions to one side for better browning, if needed.
  • Add Vegetables: Stir in the sliced carrot and celery, cooking for 3-5 minutes until softened. Add the crushed garlic and cook for another minute until fragrant.
  • Combine Ingredients: Add the can of crushed tomatoes, red lentils, bay leaf, and dried thyme. Pour in the chicken stock, ensuring all ingredients are well covered.
  • Simmer the Soup: Bring the mixture to a boil, then reduce the heat to a simmer. Cook for about 30 minutes until the lentils are soft and starting to collapse into the soup.
  • Season to Taste: Check the seasoning and add salt & pepper as needed, keeping in mind the saltiness of the bacon.
  • Serve: Ladle the soup into bowls and enjoy!

Notes

  • Red Lentils: These cook quickly and do not require soaking. However, it’s best to rinse them in a colander under cold water before using to remove any debris or excess starch.
  • Adjusting Thickness: The soup will thicken as it cools. When reheating, add a splash of water or chicken stock to loosen it.
  • Storage: Store leftovers in an airtight container in the fridge for up to 3 days or freeze for up to 4 months. If freezing, let the soup cool completely before transferring to freezer-safe containers.
