Sweet Potato Soup Recipe (2024)

FAQs

Why not to boil sweet potatoes? ›

Bake, don't boil

It intensifies their flavor and creates a richer taste compared to boiling, which can result in a watered-down, bland flavor. As the oven temperature rises (when baking), the molecular structure of the sugar molecules in the sweet potatoes begins to change.

The theory is that soaking draws out starch from inside the potatoes, helping them crisp up. I've tested soaking sweet potato fries many times, and I've found that it doesn't make them much crispier, if at all.

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.

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.

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.

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.

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.

FYI – with potatoes, you want to blend only as much as necessary to get a smooth texture. Blending them too long can make them gummy. Once all the soup is pureed you can pour it back into the pot and rewarm, or simply scoop and serve!

It's important to note that cornstarch has twice the thickening power of flour. If you need to substitute cornstarch to thicken liquid in a recipe that calls for ¼ cup (four tablespoons) flour, you only need two tablespoons cornstarch.

Can I use instant potato flakes to thicken potato soup? ›

Yes. Incredibly effective? You bet. This trick works because the instant mashed potatoes are naturally starchy and therefore are similar in form to other commonly used thickeners, such as cornstarch, only without the clumps.

Cream cheese can be a delicious and tangy thickener for mashed potatoes so it stands to reason that it can also be used to add body to your favorite silky potato soup recipes — right? The answer is yes. It only works well if you do it carefully, though.

Sweet potatoes are rich in oxalate content and can result in the formation of kidney stones. Consuming sweet potatoes in excess can result in sweet potato side effects such as Vitamin A toxicity, which is manifested in skin rashes and headaches.

Sweet potatoes are nutritious, packing a good amount of vitamin A, vitamin C, and manganese into each serving. They also have anticancer properties and may promote immune function and other health benefits.

(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.

And, if you're worried about nutrients. Don't. All foods lose some of their nutritional value once they've been cooked. But, microwaved sweet potatoes actually retain more of their nutrients as opposed to boiled sweet potatoes.
