Ingredients

  • 2 tablespoons (30 ml) olive oil
  • 2 small yellow onions about (200 grams) total, finely diced
  • 1 teaspoon fine sea salt
  • 4 cloves garlic minced
  • 1 teaspoon ground cumin
  • 1 tablespoon garam masala
  • 1 tablespoon sambal oelek
  • ¼ cup (60 grams) tomato paste
  • 2 28- ounce 793-gram cans diced tomatoes
  • 4 cups good vegetable broth
  • ½ cup (70 grams) uncooked red lentils, rinsed well and drained
  • 2 teaspoons sugar
  • ½ cup chopped fresh cilantro

Instructions

  • In a 5-quart heavy pot, heat the olive oil over medium heat.
  • Add the onions and salt and cook until softened, about 5 minutes.
  • Add the garlic, cumin, and garam masala and cook, stirring, one minute more.
  • Stir in the sambal oelek and tomato paste.
  • Add the diced tomatoes, broth, lentils, sugar, and cilantro, and stir to combine well.
  • Raise the heat to high to bring the soup to a boil.
  • Lower the heat to maintain a simmer. Cook until lentils are very tender and flavors have blended, about 30 minutes.

Notes

  1. The amount if sambal oelek used in this recipe contributes a gentle, cozy heat that's more of a background note than anything. You can easily add more if you prefer more spice, without changing anything else.
  2. Like many soups, this one gets even better as the flavors have a chance to blend. It keeps well in an airtight container in the fridge for a week or in the freezer for a year, so make it anytime you like.
  3. This recipe is adapted from The Australian Women's Weekly via a friend. I first shared it here in 2011 and have made a few tweaks over the years.
