Sweet Potato Soup Recipe (Silky Smooth) - Real + Vibrant (2024)

FAQs

Why isn't my potato soup creamy? ›

One trick to make your potato soup a little less grainy is to add some form of dairy –- cream, milk, or even cheese. Because dairy is generally creamy in texture, that characteristic will carry over into your soup. Crisis averted.

This starch will bond with the broth, causing the body of the soup to become slimy. To guard against this, it is best to mash the potatoes into the soup with a potato masher or a large fork, or to run the soup solids through a food mill to crush them.

To thicken potato soup without creating lumps, you can use a roux made of equal parts butter and flour. Melt the butter in a separate pan, add the flour, and whisk until smooth. Slowly whisk the roux into the soup, and let it simmer until thickened.

Potatoes that are low-starch and high-moisture hold together better. Yukon Gold potatoes are on the medium-starch side and will hold their shape in soups. Red potatoes fall into the low-starch category, as do smaller, newer potatoes. Fingerling potatoes will do well in soups, as will long white potatoes.

Grate a starchy vegetable like squash, pumpkin, sweet potato, or white potato into the soup and let it simmer. It will release that starch and help to thicken the liquid as it cooks.

Your soup may become grainy if the cheese or dairy curdles. With a recipe like the one that follow you shouldn't have trouble because the cheese is added as a finishing component, off heat. But to avoid “breaking” the dairy while reheating (or with other dairy-rich soups), take it low and slow.

Possibilities include cream, coconut milk, yogurt, or even pureed avocado. If you choose coconut milk, be aware that it will impart a sweet, coconut flavor, which might not be right for every soup. Yogurt will add tanginess.

Perhaps the simplest approach is to flavor your soup with salt throughout the cooking process. Instead of waiting until the end of cooking to realize your soup lacks taste, you can add a bit of salt during each phase of cooking. Doing so will help bring out the flavors of each of the ingredients.

If your soup has too much onion, one effective way to balance the flavor is by diluting it with broth or water. Start by removing a portion of the soup and setting it aside. In a separate pot, heat up some vegetable or chicken broth, or simply water, and gradually add it to the soup while tasting along the way.

How to keep potato soup from getting gummy? ›

Sear or roast your potatoes to prevent gummy soup

Searing or roasting your potatoes does more than just add extra flavor to your soup. It can actually prevent your broth from becoming gluey.

Soup Thickening Method: Cornstarch Slurry

About this method: One of the most common ways to thicken sauces and soups is with a starch-based slurry, and cornstarch is a popular choice. Cornstarch is flavorless, easy to mix up, and versatile, which makes it a go-to pantry ingredient.

Cheese: I recommend a good sharp cheddar cheese here for maximum flavor. Greek yogurt or sour cream: To make the soup extra-creamy. Salt and pepper: Add in as much as you need at the end to season your soup well.

The most classic and surefire way to thicken a broth-based soup is with a cornstarch slurry. Whisk together equal parts cornstarch (or arrowroot) and water or broth, then whisk it into the pot of soup. A good ratio to get to a pleasant thickness without your soup tasting goopy or heavy is one tablespoon.

Cornstarch is a very effective thickener, and a little bit can go a long way. Add cornstarch to a small amount of cold water or other liquid (wine or stock) and whisk into a thick slurry.

Soaking potatoes in water helps remove excess starch. Excess starch can inhibit the potatoes from cooking evenly as well as creating a gummy or sticky texture on the outside of your potatoes.

Russets or all-purpose baking potatoes are high in starch and low in moisture. In soups, they will soak up the liquid and lose their shape. This makes them the ideal choice for making creamy soups or thickening a runny soup. Try using Russet potatoes to create the perfect Loaded Potato Soup.

Cut into eighths and place in a large pot. Add enough water to just cover the potatoes, and a pinch of salt. Boil sweet potatoes for 15 to 20 minutes, until they are tender when pierced with a fork. It will take less time if you cut the sweet potatoes into smaller pieces.

(Another hot tip if you're boiling your sweet potatoes: Don't overcook them! They tend to absorb water, which could make the filling watery.) So, say you do have some undercooked bits of sweet potato. You have two choices: Pick them out or bake your sweet potato casserole long enough to soften the underdone pieces.

I've also had soups turn out too sweet if I use too much onion. I second the white wine suggestion. Carrots, onions, turnips and cabbage can all add a sweetness to soups and sometimes more than others.

How to get soup silky smooth? ›

A common mistake is to not run the blender long enough. This results in a grainy-textured soup. The soup should be blended long enough to create a silky-smooth texture. Once the soup has been fully blended, it can also be strained through a fine mesh strainer to ensure any skins or tough fibers are removed.

How do you make soup smooth? For a soup with a smooth consistency, work with veggies that are soft but not mushy. Additionally, streaming oil or cream into the soup can better emulsify the ingredients for a silkier texture. Blender features can also play a major role in getting your soup to the right consistency.

Veloute soup traditionally is a pureed vegetable soup made with broth, thickened with a little flour and finished with cream and egg yolks. (Cream soups are made with milk as the liquid instead of broth.) But it's a flexible formula.

If you slice the potatoes too thin, or pulverize them in a food processor, the veggies release extra starch that gives your soup a gluey consistency. High-intensity mashing methods like using blenders, hand mixers, or food processors overwork the potatoes, which breaks down their cells.

When adding water to your pot of potatoes, use cold water. This ensures even cooking of your potatoes. When the soup comes to a boil, reduce heat a touch to maintain a gentle boil. Boiling at too high of a temperature will break down your potatoes and make your soup grainy.

Cut the potatoes into rissolettes and blanche them (i.e. cook them briefly, not to full doneness). Use the water you used in the soup and put the potatoes back in when you go to warm the soup again for serving. Since they're cut fairly small, they should be just about done without being mushy when you go to eat.

Don't Let It Boil

Boiling is a sure way to curdle milk. It's not just boiling. Heating milk too quickly, even if it never comes to a boil, can also curdle it. To prevent the dairy from curdling, heat the milk gently over medium-low heat.
