Lentil Soup Top Tips

  • Rinse the lentils: Rinse the lentils thoroughly before cooking to remove any debris or dirt.
  • Use high-quality stock: Use a high-quality vegetable stock for the best flavor. If you don’t have any on hand, you can use water and adjust the seasoning accordingly.
  • Sauté the vegetables: Sauté the onions, garlic, carrots, and celery in olive oil for a few minutes before adding the remaining ingredients. This step will add depth and complexity to the soup’s flavor.
  • Don’t overfill the pressure cooker: Don’t fill the pressure cooker more than 2/3 full to avoid any spillovers.
  • Adjust the cooking time: Adjust the cooking time based on the type of lentils you are using. Red lentils cook faster than green or brown lentils, so adjust the cooking time accordingly.
  • Natural release: Allow the pressure to release naturally for at least 10 minutes before releasing the remaining pressure manually. This will help ensure the lentils are fully cooked and prevent any soup from spilling out.
  • Adjust the seasoning: Taste the soup and adjust the seasoning accordingly before serving. You may need to add more salt or spices depending on your personal preference.
  • Serve hot: Serve the soup hot with your favorite toppings, such as fresh herbs or a squeeze of lemon juice.

Make ahead of instructions and storage

Make-ahead instructions: You can make this soup in advance and store it in the refrigerator for up to 3-4 days or in the freezer for up to 3 months. To reheat, simply warm it up on the stovetop or in the microwave.

Storage tips: Store the soup in an airtight container or freezer-safe bag. If storing in the freezer, make sure to leave some space at the top of the container or bag to allow for expansion as the soup freezes.

Reheat instructions: To reheat the soup, simply transfer it to a pot and heat it up over medium heat until it’s hot. You can also reheat it in the microwave in a microwave-safe bowl, stirring occasionally.

Adding liquid: If the soup thickens too much after being stored, you may need to add some additional vegetable stock or water to thin it out to your desired consistency.

Toppings: Wait to add any toppings, such as fresh herbs or lemon juice, until just before serving.

Serving suggestions for Lentil Soup

  • Bread: Serve the soup with a slice of crusty bread or a warm dinner roll. It’s perfect for dipping and soaking up the flavorful broth.
  • Salad: Pair the soup with a simple green salad or a chopped vegetable salad for a light and refreshing side dish.
  • Toppings: Add some toppings to the soup to give it some extra flavor and texture. Some delicious options include chopped fresh herbs, a drizzle of olive oil, a squeeze of lemon juice, or a dollop of vegan yogurt.
  • Croutons: Make some homemade croutons by toasting some bread cubes in olive oil and seasoning with salt and dried herbs. Sprinkle the croutons over the soup for some added crunch.
  • Sides: Serve the soup alongside some roasted vegetables, like Brussels sprouts or carrots, or some grilled tofu or tempeh for a complete and satisfying meal.
