Roasted Sweet Potatoes | The Modern Proper (2024)

FAQs

Why are my roasted sweet potatoes not crispy? ›

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.

Some recipes for homemade sweet potato fries ask you to soak the fries before cooking. The theory is that soaking draws out starch from inside the potatoes, helping them crisp up.

Recipe FAQ's

The main reasons for soggy sweet potato wedges are: overcrowding the baking sheet, not tossing in enough oil, having too thick sized wedges, and not roasting at a high enough heat.

Sweet potatoes are a warm-season, frost-sensitive crop that produces best when daily maximum air temperatures are between 85° and 95°F. Temperatures over 100°F are not harmful so long as the plants are adequately irrigated and temperatures drop to below 80°F at night, although growth may be slow above 100°F.

The acid in the vinegar can also help to slightly break down the surface of the potatoes, aiding in the development of a crispier texture during frying. Additionally, the vinegar can contribute to a golden-brown color on the exterior of the fries.

If the potato is still firm when squeezed, that means it needs to cook more. Baked sweet potatoes can be stored in an airtight container in the refrigerator for up to 5 days. Reheat for 2 minutes in the microwave, at 400°F in the air fryer for 5 minutes, or at 400°F in the oven for 10 minutes.

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.

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.

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.

Unfortunately, yes! If your sweet potatoes cook too long in the oven they can overbake and become dry. The insides will become mushy. Moving your sweet potato cubes around and checking them periodically can help avoid overcooking.

Why are roasted sweet potatoes so good? ›

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.

How Long to Roast Sweet Potatoes. This recipe produces perfectly roasted sweet potatoes after about 30 minutes in an oven preheated to 425 degrees F. If you like your roasted sweet potatoes very soft, you might want to cook them a tad longer.

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.

You can control the amount of maltose produced when cooking sweet potatoes by varying the cooking time. The longer and slower you cook a sweet potato, the more maltose is formed and the sweeter it will taste.

A good rule of thumb for whole baked sweet potatoes: 45 minutes to 1 hour at 400 degrees F; 1 hour to 1 hour 15 minutes at 350 degrees F; 1 and 1/2 hours at 325 degrees F. You'll know the sweet potatoes are done by piercing the center of the sweet potato with the tip of a sharp knife; the flesh should yield easily.

Preheat the fat. While the potatoes parboil, add the oil or butter to the roasting pan, transfer it to the warm oven, and heat it for about 5 minutes before adding the potatoes. This allows the outside of the potatoes to crisp up nicely and not just absorb the cold fat when you put them in the oven.

Roasted potatoes can become soggy if the water content in the potato isn't fully cooked. Different potatoes have different water content percentages. Also, be mindful of the oil. Potatoes can react like sponges; too much oil can make your potatoes appear to be soggy.

If you roast them at too high a temperature, you risk browning the outsides before the insides are cooked through. Cook them for too long at a lower temp, though, and they may dry out (telltale signs: leathery, tough) on their way to Tender Town.

How to tell if sweet potatoes have gone bad. If your sweet potato is soft in spots, smells rotten, or oozes a mysterious liquid, that potato should be discarded. Another sign that sweet potatoes have taken a turn for the worse is if they start growing stalky purplish sprouts.
