Creamy Red Lentil and Tomato Soup with Basil
Creamy Red Lentil and Tomato Soup with Basil is the ultimate comfort food for a cold winter day. This dish combines creamy texture, rich flavors, and satisfying depth. Red lentils serve as an excellent source of plant-based protein, helping you feel full. The combination of tomatoes, onions, garlic, and basil creates layers of complexity, elevating the flavor profile of this humble soup. Not only is this recipe budget-friendly, but it also tastes gourmet, making it a staple you’ll want to revisit often.
To transform this simple soup into an unforgettable meal, there are a few key culinary tricks. Meyer lemon juice acts as a secret ingredient, adding piquancy, zest, and sparkle. The more subtle orange-lemon flavor of Meyer lemons is recommended over the tartness of Eureka lemons, though either can be used successfully. The addition of lemon is essential. Omitting it will result in a bland, unremarkable soup.
Another clever technique involves adding one teaspoon of baking powder to the soup just before stirring in the heavy cream. This step creates a creamier mouthfeel and allows for a reduction in the amount of heavy cream, from the traditional 1 ½ cups to just 3 to 4 tablespoons. The baking powder also helps retain the bright, discernible flavor of the lemon, preventing it from fading during serving or reheating. This simple addition enhances texture and preserves flavor without relying on large amounts of saturated fat.
The chemical reaction from the baking powder is undetectable in the finished dish, ensuring no compromise in taste or texture. This little-known method, often used in Scandinavian cuisine, helps reduce saturated fat by minimizing the use of full-fat dairy in legume soups. It is important not to substitute baking soda, as it will impart an unpleasant metallic or soapy taste, ruining the soup.
Serve this soup with toasted, rustic artisanal bread or homemade open-faced grilled cheese sandwiches, perfect for dipping into the hot, flavorful broth.
Creamy Red Lentil and Tomato Soup with Basil
Serves: 4 as a main; 6 as a side
Ingredients
4 tablespoons extra virgin olive oil
1 large yellow or sweet onion, peeled and chopped
1/4 teaspoon kosher flake salt
6 large garlic cloves, peeled and roughly chopped
1/8 cup plus 1 heaping teaspoon double-concentrated tomato paste
1 1/2 cups red lentils, rinsed and drained
1 large hothouse tomato, chopped
1 large red heirloom tomato, chopped
2 large plum tomatoes, chopped
5 cups filtered water
1 tablespoon honey
1 teaspoon baking powder
3 tablespoons heavy cream
Juice of 1 large Meyer lemon, about 2 tablespoons
Garnish: 1/2 cup basil leaves, hand-torn or cut into a chiffonade
Preparation
In a medium Dutch oven, heat olive oil over medium heat until warm. Add onions and a pinch of salt, sautéing until golden and soft. Add the garlic and continue to sauté until fragrant, for about 1 minute.
Stir in the tomato paste with a wooden spoon and cook for 1 minute to remove the raw flavor. Add the chopped tomatoes, filtered water, and honey. Stir to combine. Bring the soup to a boil, then immediately reduce the heat to the lowest setting and cover with a lid. Simmer gently, stirring occasionally, for 1 hour. Remove the lid and continue to cook uncovered for 30 minutes, stirring occasionally to reduce the soup.
Add the baking powder, stirring to combine until fully incorporated. Stir in the heavy cream until blended. Add the Meyer lemon juice and stir until well combined. Serve the soup in bowls and garnish with basil leaves before serving.
