Sautéing the onion‚ carrot‚ and celery cooks them down for use as a flavoring in the lentil soup․ Toasting the thyme and cumin for 30 seconds builds flavor in the broth․ The aroma cooks into the broth as the lentils simmer in the pot․

Cook the vegetables in a large soup pot or Dutch oven over medium heat for 5-7 minutes․ Add garlic and cook for 1 more minute․ Stir the dried spices constantly for 30 seconds to release their flavors without burning․ By now‚ you should be able to smell the soup․
After boiling‚ simmer lentils with the lid on for 40 to 50 minutes or until tender when tested․ I take out the bay leaf and add salt and black pepper and fresh parsley as a garnish before serving hot lentils․ The lid helps keep soup from boiling off during lentil cooking․
A small amount of lemon juice or red wine vinegar can be served with the soup for extra flavor․ Do not overpower other flavors․ Red wine vinegar is suggested․ Bread or homemade biscuits with butter are good accompaniments to serve with the soup․ Fresh salad is a good cold accompaniment option․ Italian grinder sandwiches are another good option․
Why you'll love this recipe
- The 40- to 50-minute covered cooking time helps the lentils cook in the broth․
- One pot is used to make the vegetable soup․ There is no additional pot to wash after cooking․

- Fresh parsley is an ingredient in this soup‚ but you can eat the soup without fresh parsley․
- Partially blending lentils in the pot adds flavor to the dish․ Whole lentils are also served․
- The bay leaf is taken out before serving to make sure diners don't find it in a spoonful․
