How Do You Season Sweet Potatoes?

Season sweet potatoes with salt, black pepper and garlic, a good coat of oil, and high heat. The sugar in a sweet potato does the rest: at 425°F the edges brown and caramelize, and salt is what keeps that sweetness from tasting flat. Toss cubes or wedges in about a tablespoon of oil and a teaspoon of seasoning per pound before roasting, then taste one and add a pinch more at the end. Go savory with garlic and pepper, smoky with paprika and a little brown sugar, or herby and salt-free if you would rather add the salt yourself; all three work because the potato brings its own sweetness.

That is the short answer. Below: why sweet potatoes need salt more than sugar, how much seasoning per pound, the three Flavor Seed blends that fit, and what to do for the holiday casserole crowd.

Why most sweet potatoes taste flat

A sweet potato is already sweet. Pile cinnamon and sugar on top and you get dessert, which is fine on Thanksgiving but not on a Tuesday. What a sweet potato is missing is salt, a little heat and something savory to push against the sugar.

The second problem is steam. Sweet potatoes hold a lot of water, and crowded on a pan at a low temperature they steam instead of roast. Spread them out, run the oven hot, and leave them alone long enough to brown. The browned edges are where the flavor lives.

How much seasoning per pound

For a pound of sweet potatoes (one large or two medium), use about one tablespoon of oil and one teaspoon of a salted blend. Toss them in a bowl, not on the pan, so every piece gets coated. If your blend has no salt in it, use a full teaspoon of the blend and finish with a squeeze of lime, which does some of the same job. Taste a piece when they come out of the oven; a last pinch on the hot pan is rarely wrong.

Cubes, wedges, whole or mashed

Cubes and wedges: 425°F, cut side down on a hot pan, 25 to 35 minutes, flipped once. Season before roasting so the oil carries the garlic and pepper into the potato.

Whole baked: 400°F for about an hour, until a knife slides in with no resistance. Season after: split it open, add butter, then salt, pepper and garlic. The flesh is too wet to hold seasoning before it bakes.

Mashed: season in two stages. Salt the cooking water lightly, then taste the mash and add garlic, pepper and a little more salt at the end.

The three Flavor Seed blends that fit sweet potatoes

For everyday roasting: The OG. Sea salt, organic garlic, organic black pepper. That is the whole label, and it is exactly what a sweet potato wants: salt to lift the sweetness, garlic and pepper to give it something savory to lean on. A teaspoon per pound before roasting, a pinch after. It is the same shake we use on every other roasted vegetable, so one pouch covers the whole pan.

For smoky, sweet-and-salty wedges or fries: Smoke 'Em If You Got 'Em. Sea salt and organic brown sugar lead, then garlic, paprika, onion and black pepper, with mustard seed, cayenne, ginger and ancho chile behind them. The brown sugar helps the edges caramelize and the paprika and ancho give that barbecue-side-dish taste. It comes in the resealable pouch only. If you are roasting sweet potatoes next to pulled pork or ribs, this is the one; the whole plate tastes like it was planned.

For a no-added-salt pan: Zilch. Nada. None. Fourteen organic herbs and spices and no salt: onion and garlic first, then turmeric, paprika, celery seed and coriander, with basil, oregano, dill, black pepper, parsley, thyme, cayenne and cumin behind them. The turmeric turns the cubes a deep gold and the onion and garlic do the savory work that salt usually does. Use a full teaspoon per pound and finish with lime. It is the blend that runs through our low-sodium Thanksgiving plate, and sweet potatoes are one of the places it shines.

What about the Thanksgiving casserole?

Sweet potato casserole is a dessert that sits next to the turkey, and we are not going to talk you out of it. Even so, a pinch of salt in the mash makes the brown sugar taste like more brown sugar. If your family is split between the marshmallow camp and the savory camp, roast a pan of garlic-and-pepper cubes alongside it. In our experience the cubes disappear first and nobody admits it.

Quick fixes

Bland: salt first, then a squeeze of lime, then taste again. Mushy and pale: the oven was too low or the pan too crowded; spread them out and go to 425°F. Burnt edges with a raw middle: cut them smaller and more evenly. Too sweet: more salt, more pepper, a pinch of cayenne. Stuck to the pan: let them sit two minutes; they release as they cool.

Quick answers

What spices go well with sweet potatoes?

Salt, black pepper and garlic are the base for savory sweet potatoes. Smoked paprika, cumin, cayenne and a little brown sugar take them toward barbecue. Cinnamon, nutmeg and ginger take them toward dessert. Salt belongs in every version, sweet or savory, because it is what keeps the natural sugar from tasting flat.

Do you season sweet potatoes before or after roasting?

Before, for cubes and wedges: toss them in oil and seasoning so the oil carries the flavor onto every surface and the salt helps the edges brown. Then taste one when they come out and add a final pinch if they need it. For whole baked sweet potatoes, season after, once they are split open and buttered.

How do you make sweet potatoes less sweet?

Add salt, pepper and something savory like garlic or onion, roast them hot so the edges brown rather than steam, and finish with acid, like lime juice or a splash of vinegar. A pinch of cayenne or smoked paprika also balances the sweetness without adding sugar.
