If you’re soup tastes bland, adding something acidic will help bring out the flavors. Try adding a splash of apple cider vinegar or a squeeze of lemon juice. For a more rich flavored soup, add 2-3 tablespoons tomatoes paste or a sprinkle of parmesan cheese. Another option to enhance the flavor is to add additional herbs such as bay leaves, oregano, or basil and season with salt and pepper to taste.
