Ingredients

  • 1 bag lentils (dry) Goya lentils you'll find in every supermarket, linked for reference
  • 12 ounces bacon (thick-cut) thick-cut bacon is preferable, but regular bacon works, too - see blog post for more details
  • cups onion diced, 1-2 small onions, or 1 medium onion
  • 1½-2 cups carrots diced, 1-2 carrots
  • 2 whole bay leaves recommended, but optional
  • 64 ounces beef stock beef broth works, too
  • ¼-½ cup white wine vinegar please refer to the notes section as to why I am giving a range
  • ⅛-⅓ cup sugar please refer to notes why I am giving a range
  • salt and pepper to taste
  • 4 links beef franks sliced, about 11-12 oz depending on the brand

Instructions

  • In a large soup pot, cook the bacon over medium heat.
  • Once the bacon starts to cook a bit, add a splash of beef broth and the diced onions. Sauté the onions for about 10 minutes.
  • Add the dry lentils to the pot. Stir them well so they mix with the bacon and onions.
  • Pour the rest of the beef stock into the pot. If you're using bay leaves, add them now. Cover the pot with a lid and bring everything to a boil.
  • Once the soup is boiling, turn the heat down to a simmer. Let it cook for 15 minutes.
  • After 15 minutes, add the diced carrots to the pot. Keep the soup simmering for another 15-20 minutes or until the carrots are tender.
  • Now it’s time to make it just how you like it! Add white wine vinegar, sugar, salt, and pepper to taste.
  • If you're using diced beef franks, add them now. Let them simmer until they're warm, which should take about 1 minute.
  • Serve your soup hot. If you like, you can add some fresh parsley on top for garnish.

Notes

 

VINEGAR & SUGAR

White wine vinegar is perfect for this recipe. Red wine works, too. The reason why I like to add vinegar is twofold. First, it's quite delicious, especially when well-balanced against sugar. Secondly, the vinegar's fermented acids help make lentils easier to digest. 
I am giving a range of how much vinegar and sugar to add. Quite frankly, it really depends on your preferences. However, I recommend adding at least ¼ cup of vinegar and 2 tablespoons of sugar to start. This amount will give the soup a lift but not overpower the soup. 
Stir, season with salt and pepper, and see if you like to add more.
In Germany, it's not uncommon that a family will serve lentil soup and vinegar and sugar as condiments so family members can season it to their own liking.
