Oven Roasted Sweet Potatoes Recipe (2024)

FAQs

Why do you soak sweet potatoes before roasting? ›

The cold water bath helps rinse the starch off the sweet potatoes so they're a bit more crispy. That said, if you do not have the time, you can still get crispy baked sweet potato fries by using high heat and a little drizzle of olive oil.

Preheat the oven to 425°F and place a piece of foil on a baking sheet. Use a fork to poke holes into the sweet potatoes, set them on the baking sheet, and roast for 40 to 50 minutes, or until puffed up and soft inside when pierced with a fork.

I've found that sweet potatoes really need space for a truly roasted, crisped-edge result. Aim for about one inch of space between pieces. This leads to good, dry, hot airflow that will let the potato pieces' moisture evaporate while letting them dry and crisp up more.

Wrapping the sweet potatoes in foil ensures that they don't dry out too quickly, and allows you to add aromatics if desired. Unwrapping the sweet potatoes and increasing the oven temperature produces charred, roasted flavors and caramelizes converted sugars.

Yes! Soak the potatoes in cold water to remove the excess starch from the outside of the potato. There are a few reasons why you want to remove that starch (it makes the potatoes burn, it keeps them from crisping up, it turns to sugar) but all you really need to remember is to soak them at least one hour.

The choice between orange-fleshed or white-fleshed sweet potatoes is a matter of personal preference. Can I make this dish ahead of time for a holiday meal? Yes, you can absolutely prepare these sweet potatoes ahead of time by roasting them and making the butter.

Do you have to poke holes in sweet potatoes before baking? Typically holes are poked into a sweet potato to prevent a potato exploding in your oven. However, the chance of that happening is low, and according to Lifehacker, sweet potatoes will retain more flavor if you don't poke them.

Generally, diced sweet potatoes take 7 to 12 minutes; cubed sweet potatoes take 12 to 15 minutes; and whole potatoes take anywhere between 20 to 50 minutes, depending on size.

The longer and slower you cook a sweet potato, the more maltose is formed and the sweeter it will taste. So if you want a much less sweet potato try steaming it, or cut it into small pieces and roast on a higher heat.

One of the phenols, called chlorogenic acid, is the culprit that makes sweet potatoes, and sometimes, regular potatoes darken when they're cooked. The chlorogenic acid combines with iron ions in the potato and oxygen absorbed from the atmosphere and cooking water, creating the dark pigment.

Why are my roasted sweet potatoes mushy? ›

Typically when you roast sweet potatoes, they end up mushy, not crispy. That's because the high sugar content and moisture in the potato creates a softer result. In this case, they get their crispiness not by deep frying, but by sprinkling a secret ingredient over and baking them!

The salt and pepper accent the potatoes' sweetness, creating a delectable sweet and savory flavor. I also love how the cubes puff up as they bake, becoming lightly crisp and caramelized on the outside and tender in the middle. And third, they're just so versatile.

Trapping that spud in aluminum foil where the moisture cannot escape results in a wet potato. Over baking the potato in foil cannot be seen (or easy to smell that it is overcooked) so you can end up with dark brown skin on the bottom, tough to eat and giving off a slightly burnt taste.

As with boiling, calories, carbohydrate and fat were higher in the baked sweet potato per 100g, but protein was higher in the baked white potato (2.2 g vs 1.6g per 100g). Baked sweet potatoes contained more than double the fibre of the regular potato, with less starch but a lot more sugar.

They're dirty! Washing the sweet potatoes not only eliminates actual particles of dirt, but it also introduces some moisture to the skin, which prevents it from turning tough or leathery in the high heat of the oven.

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. Cold water is used because hot water would react with the starch activating it, making it harder to separate from the potatoes.

Why use salt water for soaking potatoes? There's moisture naturally found in potatoes, and moisture is drawn to higher concentrations of salt. (This is a process called osmosis.) So, if you put the potatoes in a salt water bath, that will help draw out some of their moisture, resulting in crispier fries.

Don't Overcrowd Your Baking Sheet

The secret to crispy (instead of soggy) sweet potato fries is to spread them out in an even layer with enough room so that they don't touch. This is especially important if you're making a big batch of fries.

Some recipes call for soaking the sweet potatoes in water before cooking them to help remove some of the starch and make them more crispy but have found that this step isn't necessary for sweet potatoes as they don't have as much starch as regular potatoes.
