There’s something so comforting about a perfectly roasted sweet potato. It’s soft and fluffy inside with a little crisp on the outside. I like to serve it with a sprinkle of sea salt and a butter, or sometimes with a spoonful of Greek yogurt and herbs for a quick healthy side that goes with almost anything.

Two split roasted sweet potatoes are topped with mashed filling, a pat of butter, chopped green onion, and parsley on a plate.

It’s also family-friendly and pairs well with just about anything!

🛒 Ingredients

  • Sweet potatoes - I love using larger ones for a hearty portion. Smaller ones work too, but adjust baking time.
  • Olive oil - Gives the skin a lovely crispness. Any good-quality olive oil will do, and you can skip it if you don’t plan to eat the skin.
  • Salt - Don’t be shy with it, especially if you like flavor depth. Sea salt flakes are my favorite finish.
  • Black pepper - Freshly cracked for that extra flavor kick.
  • Butter - Totally optional but makes them irresistible.
  • If you like more healthy side recipes, try honey glazed carrots, roasted zucchini & squash, or braised korean potatoes next.

🥣 How To Make Roasted Sweet Potatoes

  1. Prepare the sweet potatoes: Give the sweet potatoes a good rinse under warm water, scrubbing them well to remove any dirt since you’ll be eating the skin. I usually use a vegetable brush for this. Once they’re clean, pat them completely dry with a kitchen towel so they roast instead of steaming in the oven.
  2. Pierce the potatoes: Use a fork or knife to pierce 4–5 holes all around each potato so they cook evenly and do not burst.
  3. Season the potatoes: Place them on a foil- or parchment-lined baking sheet, rub with olive oil, and season with salt and pepper.
  4. Bake the sweet potatoes: Place in a preheated oven at 425 F and bake for 30 minutes.

Rita's Tip: If you roast often, I recommend a heavy-duty nonstick sheet pan and a soft-bristle veggie brush—they make prep and cleanup so much easier.

  1. Flip and finish baking: Carefully flip the potatoes with tongs and bake for another 30 minutes until they are soft inside.
  2. Serve and garnish: Let the potatoes rest for 5 minutes, cut them open, and top with butter, salt, and pepper.

Rita's Tip

Always poke holes before baking to keep sweet potatoes from bursting and ensure even cooking.

👨‍🍳 Rita's Favorite Equipment

  • Baking sheet or casserole dish (13-inch) – Either works great! The baking sheet helps the skin crisp up, while a casserole dish keeps things a bit softer and cozier if you prefer that style.
  • Parchment paper or foil – Makes cleanup quick and prevents sticking.
  • Tongs – Handy for flipping the potatoes halfway through baking.
  • Vegetable brush or clean kitchen sponge – Perfect for scrubbing dirt off the skins before roasting.
  • Sharp knife or fork – I use and love this Henckels knife set, you can find it here.

📋 Tips

  • Massaging with oil isn’t required but makes potato skins delightfully crisp.
  • Use foil or parchment so cleanup is easier.
  • Sea salt flakes at the end give a nice flavor boost.
  • You can swap olive oil for avocado oil or skip oil if you prefer.
  • Piercing holes is worth it for perfect baking.
  • Cutting open right after resting keeps them fluffy.
  • Add cinnamon or brown sugar for a sweet twist.

🍱 Storage Instructions

  • 🍱To Store. Store cooled sweet potatoes in an airtight container in the fridge for up to 4 days.
  • 🥶Freezing. Wrap individually in foil and freeze for up to 3 months.
  • 🔥To Reheat. Microwave or reheat in a 350 F oven until warmed through.

What To Serve With Roasted Sweet Potatoes

  • Grilled chicken or salmon
  • A fresh green salad
  • Roasted vegetables
  • A simple bowl of soup

FAQ

Do I need to wrap the sweet potatoes in foil?

No, baking them unwrapped directly on the sheet gives the skin a better chance to crisp up, foil traps steam and makes the skin softer.

How do I know when they're done?

They're ready when a fork or knife slides easily into the center with no resistance, usually 45 minutes to an hour depending on size.

Can I roast different sized sweet potatoes together?

Yes, just check the smaller ones a little earlier since they'll cook faster than the larger ones.
