Sweet Potato Soup With Feta and Za’atar Oil Recipe (2024)

FAQs

What is a good thickener for potato soup? ›

Combine cornstarch and a little bit of water—or the chicken stock from the soup—in a small bowl. With the soup simmering over medium-low heat, whisk in the slurry. The soup should start to thicken almost immediately.

Boiling may actually retain most of the antioxidant power of sweet potatoes, compared to roasting and steaming. If we compare baking to boiling microscopically, boiling helps thin out the cell walls and gelatinize the starch, which may enhance the bioavailability of nutrients.

The recommended method here is to press the potatoes through a ricer (instead of using a blender), which gives the soup a light and clean texture and eliminates the gluey consistency common in other recipes.

It's important not to chop them too finely before cooking. Keeping them in medium-ish sized chunks should work best. If the potatoes are chopped too finely, then too much starch will be released into the broth, resulting in a gummy-like texture.

Add Flour Or Cornstarch

You can thicken soup by adding flour, cornstarch, or another starchy substitute.

Starchy Vegetables

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.

Despite their sweet taste, these potatoes have an intermediate glycemic index (GI) level, meaning they are digested and absorbed fairly slowly, leading to a more gradual increase in blood sugar levels. But, a lot of these benefits, including nutrients and taste, can be lost by boiling sweet potatoes.

Boiling sweet potatoes retains more beta-carotene and makes the nutrient more absorbable than other cooking methods such as baking or frying. Up to 92% of the nutrient can be retained by limiting the cook time, such as boiling in a pot with a tightly covered lid for 20 minutes.

There is not much difference between boiling sweet potatoes with the skins on versus peeling them, but you will get a boost of fiber and potassium if you keep the skin on. The skin also adds a subtle texture to each bite. If you're looking for a smoother mash, peel the potatoes first before boiling.

Let's test her vichyssoise recipe to find out! Soup was one of Julia Child's favorite things to eat, and reportedly, her absolute favorite was vichyssoise.

Why is my potato soup bland? ›

Not Adding Acid. If a soup is tasting bland in the bowl, consider adding acid rather than salt. A squeeze of lemon or lime, or a dash of yogurt or sour cream can add brightness to the bowl.

To replace 1 cup (237 mL) of heavy cream in your recipe, add 2 tablespoons (19 grams) of cornstarch to 1 cup (237 mL) of milk and stir, allowing the mixture to thicken. You can use whole milk or opt for skim milk to help slash the calories and fat content of your recipe.

So what do you do if you've made the mistake of using starchy potatoes in your soup? 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.

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.

But when heat is introduced, the protein structure falls apart and the emulsion breaks—the fat globules come together into a greasy pool and the proteins congeal to form a stringy mess.

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.

Cornstarch, or corn flour, can be used to thicken soup through its high starch content. Cornstarch is a great thickener for soup because only a little bit is needed to significantly thicken a soup, and it will not affect the flavor profile of the soup.

Add a Thickening Agent

This is the most common way to thicken mashed potatoes. You can use what you have on hand: Flour, cornstarch, or powdered milk are all solid options that are probably already in your pantry.

Sear or roast your potatoes to prevent gummy soup

When you get your potatoes fired up in the oven or on the stovetop, you expose their starches to the Maillard reaction that creates a nice, darkened crust. This gives the starches a chance to break down without absorbing excess moisture.
