Nutrition Notes

Are Sweet Potatoes Healthy?

Sweet potatoes provide complex carbohydrates for energy, fiber to keep things moving through your gut and a little bit of plant protein. They're loaded with vitamin A and also offer a good amount of vitamin C and potassium. The type of fiber in sweet potatoes is resistant starch, which acts as a prebiotic, feeding your beneficial gut bacteria. Sweet potatoes have been associated with a healthy heart, gut and eyes.

Tips from the Test Kitchen

What Herbs Go Well with Sweet Potatoes?

This simple recipe calls for just salt and pepper, but you don't have to stop there. You can jazz up sweet potatoes with herbs, spices, nuts and even cheese after (or before) they're done roasting. Dried spices like chili powder or smoked paprika pair nicely with roasted sweet potatoes and are best added before they hit the oven. Fresh herbs like thyme, basil or rosemary lend the most flavor when they're added after the sweet potatoes are done roasting. Tossing chopped nuts or crumbled cheese like goat cheese or blue cheese with roasted sweet potatoes a few minutes after they leave the oven is a great way to add flavor and texture.

What Should I Serve with Sweet Potatoes?

This easy side dish can be prepared for a weeknight dinner and pairs well with many main dishes. Crispy Roast Chicken, Steak au Poivre, Skillet Lemon-Garlic Salmon and Lemon-Balsamic Chicken Thighs make a delicious accompaniment to these roasted sweet potatoes.

Roasted sweet potatoes can also be incorporated into other dishes, like Sweet Potato, Sausage and Goat Cheese Egg Casserole, Spinach Salad with Roasted Sweet Potatoes, White Beans & Basil, Kale & Roasted Sweet Potato Hash and Sweet Potato Hummus.

Frequently Asked Questions

What Is a Prepared Baking Sheet?

We line a large rimmed baking sheet with foil, then coat the foil with cooking spray before the sweet potatoes are added to the pan. Since the oven is on the hot side (425°F), the foil acts as a layer of insulation that will prevent over-browning. (Plus it will make cleanup a lot easier!) In order for the sweet potatoes to cook evenly, you'll have to turn them once halfway through cooking. A layer of cooking spray on the pan makes this a whole lot easier and prevents the potatoes from sticking.

Why Cook Potatoes with Skin On?

While you can peel your sweet potatoes, we prefer to leave the skin on. This saves time and also adds flavor and texture as well as a boost of fiber. If you're leaving the peel on, be sure to scrub the potatoes with a vegetable brush or clean scrubber sponge to remove any dirt and debris.

Nutrition information is calculated by a registered dietitian using an ingredient database but should be considered an estimate.

* Daily Values (DVs) are the recommended amounts of nutrients to consume each day. Percent Daily Value (%DV) found on nutrition labels tells you how much a serving of a particular food or recipe contributes to each of those total recommended amounts. Per the Food and Drug Administration (FDA), the daily value is based on a standard 2,000 calorie diet. Depending on your calorie needs or if you have a health condition, you may need more or less of particular nutrients. (For example, it’s recommended that people following a heart-healthy diet eat less sodium on a daily basis compared to those following a standard diet.)
