There's science behind the diet tip to eat filling soup when the soup is a thick, blended puree. A study published in the Journal of Nutrition found that you'll feel fuller for an hour longer than you would if you ate the same ingredients in their whole form while sipping a glass of water. Think of a pureed soup as a savory smoothie, perfect for cool weather.
It's fast and easy to turn a cooked vegetable like squash, carrots, peas or sweet potatoes into a hearty meal with a traditional or immersion blender, or a food processor. Cauliflower is particularly versatile because, as a soup base, it will take on the taste of whatever herbs, spices or other ingredients you flavor it with.
If you're short on time, you can use frozen vegetables. If you want to start from scratch, bring out the most flavor by roasting the vegetables in the oven. Alternatively, you can sweat them on the stovetop in a small amount of oil to soften them before adding enough water to just barely cover them and simmering until tender before you puree. Try to always include onions, leeks or garlic with your other vegetables for extra flavor.
Try different vegetable variations to excite your taste buds, and consider adding lentils for even more fiber and thickness. Blend in a cooked pear or apple when you want extra sweetness.
Pureed soups are delicious and convenient for lunch at home, work or on the go, and for a no-fuss, do-ahead dinner that just needs reheating.
