Onions, celery, and carrots are sautéed together for a traditional mirepoix base, then seasoned with thyme and marjoram to flavor the hearty barley, kidney beans, and waxy potatoes. This is a soup that will warm you through winter, but if you get a craving any other time of year, just throw in some of spring, summer, or autumn’s bounty to easily adapt this classic. This recipe comes to us from Patrice of Circle B Kitchen.

Heat the olive oil in a medium to large soup pot over medium heat. Add the onion, celery, and carrots. Sauté until the vegetables begin to soften and become fragrant, about 3-5 minutes. Stir in the tomato paste. Season with the dried marjoram, thyme, salt, and pepper. Sauté for 3-5 minutes, stirring so the flavors meld and the spices are evenly distributed.
Add the barley, lentils, potatoes, and kidney beans and stir to combine. Pour in enough water to cover the soup contents by about 2 inches. Stir to combine, cover partially, and simmer for about 1 hour. Remove the soup from the heat and let sit a few minutes before serving. Top with the parsley and enjoy.
