Light creamed soup is a smooth, gently rich soup made with vegetables, broth, and a modest amount of milk rather than a heavy pour of cream. This flexible version uses cauliflower and potato for a naturally velvety texture, with a little butter and milk to round it out; serve it warm as a starter or a simple lunch.
Ingredients
- 1 tablespoon unsalted butter (14 g)
- 1 medium yellow onion, chopped (about 1 cup / 150 g)
- 2 garlic cloves, finely chopped (about 6 g)
- 1 medium head cauliflower, trimmed and cut into small florets (about 1½ lb / 680 g)
- 1 medium russet potato, peeled and diced (about 8 oz / 225 g)
- 4 cups low-sodium vegetable broth (960 ml), plus a little extra if needed
- ½ teaspoon fine salt (3 g), plus more to taste
- ¼ teaspoon freshly ground black pepper (about 0.5 g)
- ½ cup 2% milk (120 ml), warmed slightly; use whole milk for a richer soup
- 1 teaspoon fresh lemon juice (5 ml), or to taste
- 2 tablespoons chopped chives or parsley (about 6 g), for serving
Instructions
- Prepare the vegetables. Chop the onion and garlic, cut the cauliflower into evenly sized florets, and dice the potato. Keeping the pieces fairly small helps them soften at the same rate. Measure out the broth and milk before you begin cooking.
- Soften the aromatics. Melt the butter in a large heavy-bottomed pot or Dutch oven over medium heat. Add the onion and cook for 5 to 6 minutes, stirring occasionally, until soft and translucent but not browned. Add the garlic and stir for about 30 seconds, just until fragrant.
- Simmer until tender. Stir in the cauliflower, potato, broth, salt, and pepper. Bring the liquid to a gentle boil, then reduce the heat so it simmers steadily. Cover the pot with the lid slightly ajar and cook for 20 to 25 minutes, stirring once or twice, until the potato and cauliflower are very tender when pierced with a fork. If the liquid boils hard, lower the heat to prevent scorching.
- Blend until smooth. Remove the pot from the heat. Use an immersion blender to puree the soup until creamy, keeping the blender head submerged to reduce splashing. Alternatively, let the soup cool briefly and blend it in batches in a countertop blender; do not fill the blender more than halfway, and vent the lid according to the manufacturer’s directions because hot liquid expands. Return the blended soup to the pot.
- Add milk and finish. Stir in the warmed milk. Set the pot over low heat and warm the soup gently for 2 to 3 minutes, stirring often; do not let it boil, since boiling can cause milk to separate. Stir in the lemon juice, taste, and adjust the salt and pepper. If it seems thicker than you like, add broth a few tablespoons at a time until it reaches a spoonable consistency.
- Serve. Ladle into warm bowls and finish with chopped chives or parsley and a little black pepper. Serve promptly while hot.
Tips
- Cut vegetables evenly. Similar-sized cauliflower florets and potato pieces cook at roughly the same pace, making it easier to blend a uniformly smooth soup. The vegetables should be very tender before blending; firm pieces can leave a grainy texture.
- Blend with care. An immersion blender is the simplest choice. For a countertop blender, work in batches, leave room for steam to escape, and secure the lid with a folded kitchen towel only if the blender instructions permit it. Never seal hot soup in a standard blender jar without venting.
- Choose your milk thoughtfully. Two-percent milk keeps the soup light while still softening the vegetable flavor. Whole milk makes it richer; unsweetened, unflavored soy milk can replace it for a dairy-free option, though the flavor may be slightly different. Avoid sweetened or vanilla-flavored plant milk.
- Season in layers, then finish. Broths vary in saltiness, so begin with the listed amount and adjust after blending. Lemon juice brightens the soup without making it taste overtly lemony; add it gradually if your broth is already tangy.
Serving Suggestions
Serve this soup in small bowls as a first course, or make it a light meal with crusty bread, toast, or a simple green salad. For a more substantial lunch, pair it with a grilled cheese sandwich or a savory tart. A spoonful of plain yogurt, a few toasted pumpkin seeds, or a drizzle of olive oil adds contrast without overwhelming the mild cauliflower flavor. Add garnishes just before serving so herbs stay fresh and crisp toppings keep their texture.
Variations
Change the vegetables: Replace up to half the cauliflower with broccoli, peeled carrots, or peeled celery root. Carrots make the soup sweeter and more colorful; broccoli brings a stronger, greener flavor. Cut any substitute into small pieces and simmer until completely tender.
Make it dairy-free: Use 1 tablespoon olive oil instead of butter and replace the milk with unsweetened soy milk or a neutral-tasting oat milk. Check that the broth is also dairy-free. The soup will remain creamy because the pureed cauliflower and potato supply most of its body.
Add herbs or spice: Simmer a bay leaf with the vegetables and remove it before blending, or add ¼ teaspoon ground cumin or smoked paprika with the garlic. Fresh thyme also works; use 1 teaspoon leaves and remove any woody stems before pureeing.
Make it thicker or thinner: For a thicker bowl, use 3½ cups broth (840 ml); for a lighter, more pourable soup, add extra broth after blending. Avoid adding flour as a quick thickener: it can make the texture pasty and is unnecessary for this recipe.
Storage and Reheating
Cool leftovers promptly and refrigerate them within 2 hours in a shallow, covered container. The soup keeps for 3 to 4 days in the refrigerator. Reheat only the portion you need in a saucepan over medium-low heat, stirring frequently until steaming hot; for food safety, USDA guidance is to reheat leftovers to 165°F (74°C), checked with a food thermometer. Avoid a hard boil, which can make the milk separate. If using a microwave, cover loosely, heat in short intervals, and stir between intervals so the soup heats evenly.
For longer storage, freeze the soup in airtight, freezer-safe containers for up to 2 months for best quality. Leave a little space at the top for expansion. Thaw overnight in the refrigerator and reheat as described; the texture may be less silky after freezing, so whisk or briefly blend it again if needed. Do not leave soup at room temperature for extended storage.
Frequently Asked Questions
Can I make light creamed soup without cream?
Yes. This recipe contains no heavy cream: blended cauliflower and potato make it smooth, while a small amount of milk adds a gentle creamy finish. For a dairy-free soup, use olive oil and unsweetened plant milk.
Can I use frozen cauliflower?
Yes. Use about 1½ pounds (680 g) of frozen florets and add them directly to the pot. They may soften a little sooner than fresh cauliflower, so begin checking tenderness after about 15 minutes of simmering.
Why did my soup turn out grainy?
The vegetables may not have cooked until fully tender, or the soup may need more blending. Simmer it longer if the pieces are still firm, then blend again. A powerful blender usually makes the smoothest finish, but an immersion blender works well when the vegetables are very soft.
Can I make it ahead?
Yes. Prepare the soup, cool it promptly, and refrigerate it for up to 3 to 4 days. For the best texture, stir in the milk and lemon juice when reheating, though you can also make the full recipe ahead and rewarm it gently.
How can I make the soup more filling?
Serve it with bread, a sandwich, or a salad with beans. You can also top each bowl with toasted seeds or add rinsed white beans before blending; beans thicken the soup and make its flavor slightly earthier.
Can I use a different potato?
Yukon Gold potatoes work well and give a slightly buttery flavor. Waxy red potatoes can also be used, though they may blend less smoothly than russets. Peel the potato and simmer it until very tender before pureeing.
