Ingredients You’ll Need
Sweet potatoes: You’ll need 1 pound of sweet potatoes, which is about 2 medium ones. Just give them a good scrub – no need to peel them since the skin gets deliciously crispy!
Olive oil: Just 1½ teaspoons of olive oil is all you need to get them perfectly golden. This small amount helps create that amazing crispy exterior we’re all after.
Kosher salt: A quarter teaspoon of kosher salt brings out all the natural sweetness. You can use regular table salt if that’s what you have on hand.
Ground pepper: Just an eighth teaspoon of ground pepper adds the perfect little kick. Freshly ground pepper tastes best, but pre-ground works great too!
How to Make Perfect Roasted Sweet Potatoes

Step 1: Preheat your oven to 425°F. Line a large rimmed baking sheet with foil and lightly coat it with cooking spray. Cut your unpeeled sweet potatoes into 1-inch cubes – try to keep them about the same size so they cook evenly.
Step 2: Toss those sweet potato cubes with the olive oil, kosher salt, and pepper in a large bowl. Make sure every piece gets coated with the oil and seasonings.
Step 3: Arrange the sweet potatoes in a single layer on your prepared baking sheet. Don’t overcrowd them – they need space to get crispy! Roast for 20 minutes, turning them once halfway through, until they’re lightly browned and tender inside.

Serving Ideas
These roasted sweet potatoes make an amazing side dish for so many meals! They’re perfect with crispy roast chicken, grilled salmon, or even mixed into a fresh spinach salad. You can also toss them into breakfast hash or add them to grain bowls for a complete meal.
Storage
Let your roasted sweet potatoes cool completely, then store them in an airtight container in the fridge for up to 5 days. To reheat, pop them in the microwave on medium power for 1-minute intervals, or better yet, reheat them in a 400°F oven for about 15 minutes to get them crispy again.
Substitutions
No olive oil? You can use avocado oil or melted coconut oil instead. If you don’t have kosher salt, regular table salt works fine – just use a little less since it’s more concentrated. You can also swap the black pepper for paprika or garlic powder if you want to change up the flavor.
Pro Tips
- Don’t skip the foil: It prevents over-browning and makes cleanup so much easier!
- Keep pieces uniform: Same-sized cubes cook at the same rate, so you won’t have some burnt and others undercooked.
- Don’t overcrowd: Give those sweet potatoes space to breathe for maximum crispiness.
- Turn once: Flipping them halfway through gives you crispy edges on multiple sides.
FAQs
What herbs go well with sweet potatoes?
You bet there are tons of options! This simple recipe uses just salt and pepper, but you can jazz it up however you like. Try adding dried spices like chili powder or smoked paprika before roasting. Fresh herbs like thyme, basil, or rosemary taste amazing when added after they’re done cooking. You can even toss in some chopped nuts or crumbled goat cheese while they’re still warm!
What should I serve with sweet potatoes?
Sure! These roasted sweet potatoes pair beautifully with so many main dishes. Try them with crispy roast chicken, steak, or lemon-garlic salmon for a delicious dinner. You can also mix them into egg casseroles, spinach salads, or breakfast hash for variety.
What is a prepared baking sheet?
Great question! We line a large rimmed baking sheet with foil, then coat it with cooking spray before adding the sweet potatoes. The foil acts like insulation at 425°F to prevent over-browning, plus it makes cleanup a breeze! The cooking spray helps prevent sticking when you flip them halfway through.
How should I store and reheat leftovers?
No worries – leftovers are easy! Once they’re completely cool, pop them in an airtight container in the fridge for up to 5 days. For reheating, use your microwave on medium power in 1-minute intervals, or for the crispiest results, reheat them in an air fryer, toaster oven, or regular oven at 400°F for about 15 minutes.
